Modern education should be personally significant for a child, helping to self-determine in life, solve emerging life problems, navigate the huge flow of information that is falling from all sides?

School education should go beyond the solution of standard, typical tasks, where the answers to all questions are already known in advance. It is necessary to introduce modern pedagogical technologies, in which the activity of students in the classroom comes first, when the teacher and student are in a “subject-subject” relationship.

Federal state standards of the second generation are aimed at developing the "ability to learn" among students and the development of universal learning activities (ULA) in classroom and extracurricular activities.

The formation of UUD is an important task of educational relations and an integral part of the fundamental core of general education. The development of UUD is the psychological basis for the success of students in mastering the subject content of physics.

To date, in the practice of teaching physics, work on the development of UUD is carried out spontaneously. The spontaneous and random nature of the development of UUD is reflected in the acute problems of teaching physics:

- low level of educational motivation and cognitive initiative of students;

- the ability to regulate their educational and cognitive activities;

- insufficient formation of general cognitive and logical actions.

The teacher needs modern tools: modern methods and forms of education and upbringing, effective pedagogical technologies of a system-activity orientation. One of such pedagogical technologies is the theory of inventive problem solving - TRIZ technology, the author of which is G.S. Altshuller.

At the end of the 20th - beginning of the 21st century, TRIZ pedagogy is increasingly being introduced into education, techniques and methods that help teach schoolchildren to search, analyze, process and use the "missing" information, can significantly increase the activity of students and consider new forms of conducting a lesson as part of the introduction GEF.

N.N. Khomenko, based on TRIZ technology, developed the General Theory of Strong Thinking (OTSM-TRIZ), in which he proposed the use of OTSM-TRIZ models.

Models are studied today in school subjects, including physics lessons (material point, ideal gas, Brownian motion, atomic models, mathematical pendulum, etc.).

In our pedagogical activity at physics lessons, at the level of basic general education, we use one of the OTSM-TRIZ models - the model "Element - Feature Name - Feature Value" ("EIZ").

"EIS" is a tool that allows you to describe the objects of the surrounding world through their features (purpose, shape, color, etc.). Distinctive features of the model are the separation of the concepts of "feature name" and "feature value", the selection of features that are significant in a given situation.

How is the EIS model structured? This is a table in which the exclamation mark indicates the given part, and the question mark the part to be found (see table 1).

Table 1.

General view of the EIZ model

With the help of the EIS model, any physical elements can be considered: bodies, substances, phenomena, quantities, formulas, laws, theories, etc.

So, based on the model "Element - feature names - feature values" tools are built:

– to describe and study objects;

– to describe and study objects as systems;

– to describe and study problems that arise in systems.

Working with the EHI model becomes more difficult from grade 7 to grade 9. In grade 7, models are given to students with missing elements, and in grade 9, students independently form models in the course of learning activities.

When working with the EIS model, the following levels were identified:

1. Elementary level aimed at the formation of skills:

– describe changes in the values ​​of the attributes of the element and the relationship between them;

– track changes in the model depending on the change in the values ​​of features;

– move from specific descriptions to more general ones and vice versa.

1. Sufficient level aimed at the formation of skills:

- build a description of the object based on the function of the object;

- describe the element by common features;

– predict changes in the system of the object.

Let's consider examples of assignments for the formation of the concept of mass among students of the 7th grade using the "EIZ" model.

1. I was asked questions about a physical quantity - mass. I answered the first question: m. For the second question: kg. For the third question: scalar. To the fourth question: m=Vρ. To the fifth question: scales. What questions did they ask me?

Table 2 shows the type of task.

Table 2.

Task execution result:

1st question: What letter represents the value?

2nd question: In what units is the value in SI measured?

3rd question: Which quantity is vector or scalar?

Question 4: How can the value be calculated?

5th question: How can the value be measured?

1. Make up a story about the mass using the EIZ constructor according to the plan:

1) What letter represents the quantity?

2) In what units is the value in SI measured?

3) What quantity is vector or scalar?

4) How can the value be calculated?

5) What instrument can be used to measure the value?

Table 3 shows an option for solving the task.

Table 3

Task execution result

1. Write a riddle using the EIS model.

Task execution result:

This physical quantity is measured in SI in kg. Scalar value and it can be calculated by the formula = Vρ. It can be measured with a scale. What is this physical quantity?

1. Question of the teacher to the class: Guess what I guessed? Fill in the gaps in the EIS model. A sample task is presented in table 4.

Table 4

Thus, from the practice of applying the system of tasks for working with the "EIS" model in the process of teaching physics, we can conclude that the use of OTSM-TRIZ models contributes to the formation and development of cognitive UUD in students such as recognition, comparison, feature extraction, generalization, classification , seriation, modeling and others.

The formation and development of cognitive UUD ensures the development of the child's personality in the system of physical education and can be achieved using a system of tasks developed using the techniques and methods of OTSM-TRIZ.

Tasks based on models should not be applied from time to time, since in the aggregate they form a system of tasks, according to which it is possible to trace the degree of formation and development of cognitive UUD. By learning how to create a system of their tasks, the teacher will be able to form students' ability to learn.

SUMMARY OF LESSONS TRIZ-seminar “ TRIZ and Chemistry” (2007)

1. Overview lecture " TRIZ in the XXI century in Russia and the world" 2 hours

1946 - mechanical engineer and employee of the patent department Heinrich Altshuller began to look for a method for solving inventive problems by studying the patent fund; (while still at school, he received an A.S. for a diver's breathing device with H 2 O 2, he made a rocket boat with H 2 O 2), after 3 years he established that the hallmark of a good patent is the resolution of a technical contradiction (one of the first decisions according to a new method - a tracking device for a traceless torpedo: the device should be small, but give a trace, noticeable both at night and during the day - he proposed the reaction of calcium phosphide with sea water supplied by a dropper; a thousand times more gas volume is formed from a drop of water - mixtures of phosphine with polyphosphines, the latter ignite phosphine in air: the flame is clearly visible at night, and the smoke-"fog" formed by phosphorus oxide is visible during the day; such a device was quickly made and classified from the author of the proposal, who did not have permission.). Ca 3 P 2 + H 2 O ==> Ca (OH) 2 + PH 3 / P 2 H 4 / P 3 H 5

P 3 H 5 + O 2 => P 2 O 5 + H 2 O + Q1; Q1 + PH 3 + O 2 => P 2 O 5 + Q2(hv); => +H 2 O => (H 3 PO 4 )(smoke)

Together with a colleague, they wrote an open letter to I. Stalin about the shortcomings in the development of inventions in the USSR and the proposed methodology, which was assessed by the NKVD as a denigration of Soviet power by a sentence of 25 years in the camp in Vorkuta. He and his co-author had previously taken part in a competition for the development of a gas rescue suit (in particular, a breathing device with liquid oxygen, the vapor of which cools the suit at the same time - according to the principle associations) - their 3 proposals for the competition took the first three places among a thousand participating inventors. They learned this decision in the camp. After 5 years, G. Altshuller was released "for lack of corpus delicti", but after the camp no one hired him - he began to be published under the name of G. Altov as a science fiction writer. And all the years he continued to work on the method of invention. In 1956 he published an article on the psychology of invention and the role of contradictions.

1961 - his first book "How to learn to invent" was published in Tambov, in 1964 - the second book "Fundamentals of Invention" was published in Voronezh, in those years I read articles in the journals R&D and Knowledge-Power by G. Altshuller and R. Bakhtamov (R. Shapiro). I remember that I ordered 10 copies of the book from Voronezh and distributed it to the Central Library of Leningrad. From the Society of Knowledge lectured Science to invent. I thought then that if I know a useful thing, I need to talk about it. tell others.

1968 in the publishing house Mosk. The worker published the book "Algorithm of Invention", in 1971 - the first two-year institute for the training of inventors began to work in Baku. In 1972, in Dubna, the Department of Invention of the MSM held a seminar by G. Altshuller for employees of enterprises, to which I was sent by the leadership of the Mayak p/o. Then I held a seminar at the Central Laboratory, which was completed by 5 people, and two soon became inventors and one became a TRIZ teacher when I left for Cheboksary, and one graduate of the seminar on the rule of dialectics became his "enemy". Now the TRIZ expert lives in Ozyorsk and is not in demand by the management.

In 1979 Sov.radio published "Creativity as an exact science" - the main book about TRIZ, which is now translated into many languages ​​of the world, and in 2004 and 2006 was republished in Petrozavodsk by the official G. Altshuller Foundation. In the 1980s, systematic TRIZ seminars began in Petrozavodsk; more than 10 books about TRIZ were published there and in Chisinau, up to 100 schools of young inventors and public universities worked in the USSR - now there is only 1 in St. (A. Kudryavtsev and V. Buentsov).

In the 70-80s, NILIM began working in Minsk, developing the Inventing Machine project and in 1989 released the programs IM-1.3 (network) and IM-1.5 (combined complex of three TRIZ methods); at the same time, she began to develop an English version of the intellectual support program based on TRIZ, in 1991 the company IMCorp, created by them, started working in Boston, releasing versions of IM - TechnoOptimizerProfi (TOP) on CD and DVD disks (for the latest version they requested 17 thousand US dollars), but as a rule, the TOP is not sold individually, but in corporate packages of 1000-1500 copies. discs and subject to training of employees of firms-buyers - the largest more than 500 global multinationals in the USA, South Korea, etc. So, today half a million engineers abroad in the Russian Federation work with the TOP program based on TRIZ, in addition, there are 3 medium-sized firms for 50-200 TRIZ experts who help customers solve their problems of development and forecasting of production based on ZRTS, there are also hundreds of small firms of TRIZ consultants, both from former inventors from the USSR and from Americans who attended the TRIZ course for 1 day. There is a package TOP-2.5 (1997) on two CDs (with V/F).

At a meeting in Petrozavodsk in 1989, it was decided to create the TRIZ Association, which has now become international: it includes 20 TRIZ PAs from the Russian Federation (for example, Karelia, St. Petersburg, Krasnoyarsk, Moscow, Cheboksary, etc.), several associations of Belarus, Ukraine, USA, EuroTRIZ, France, associations are being created in Peru, Italy, Spain, South Korea, China, etc. TRIZ conferences and MATRIZ congresses are held every 2 years in the Russian Federation; conferences in AITRIZ in the USA and in EuroTRIZ annually. In 2006, TRIZ conferences in Spanish began to be held in Mexico. Abroad, both the application of the elementary foundations of TRIZ by engineers of firms and the deep knowledge of the foundations of TRIZ specialists from the former USSR are being developed. Thus, LZh and Samsung engage TRIZ specialists under a contract for 1-3 years. In the USA, on the basis of TRIZ, firms such as Investment Machine Corporation (IMCorp., Boston), Ideation International Incorporation (III, Detroit), Pragmatic Vision (Boston) and about 100 small firms of TRIZ consultants solve problems for corporations, many TRIZ specialists work in other countries : Germany, France, Austria, etc. In particular, TRIZ-specialists help companies working on new types of fuels for internal combustion engines (ethanol, bio-fuel, hydrogen, etc.).

In the Russian Federation, the development of TRIZ pedagogy for kindergartens, schools and universities continues - MSIU has an MNTsNKO, in Inteko (Moscow) and Nord Service (Irkutsk) there are TRIZ-profi groups on the application of TRIZ in practice and on the development of TRIZ pedagogy, Children's Art Centers work with children on the basis of TRIZ in St. Petersburg, Petrozavodsk, Sosnovy Bor, Ulyanovsk, Norilsk, Novosibirsk, Chelyabinsk, Angarsk, Krasnoyarsk and other places in the Russian Federation, in Minsk and Gomel, Belarus, Odessa, Dnepropetrovsk, Ukraine.

For 30 years in the Chuvash State University, 500 copies have been collected in the library. 25 titles of books about TRIZ for students (published in 1968 - 2005), 1000 copies. 11 textbooks published at ChuvGU (1976 - 2005), about 17 thousand patents were collected for the database on the applications of chemistry in TRIZ with the participation of 1000 students, a fragment of 1550 abstracts was exhibited in en/(including also 400 abstracts from the 17th Mendeleev Congress (Kazan, 2003) and 300 abstracts from the 18th Mendeleev Congress dedicated to nanotechnologies). More than 80 textbooks about TRIZ (ChuvGU, TolGU, SPbMUNTTR, etc.) and materials on TRIZ and chemistry have been collected on a CD-ROM, 9 video films about TRIZ on DVD-ROMs.

I am looking for people who want to cooperate on the classification of about 10,000 patents based on applications of chemistry and in ecology (environmental protection).

2. Modern methods of problem solving. 6 o'clock

Examples of the use of TRIZ in creative solutions at Mayak (in the 70s): precipitation of metal hydroxides from kerosene solutions of their complexes (based on the principle homogeneity), electrodeposition of metals from solutions in kerosene (2 a.s. V. Mikhailova et al.: 75785, 1973; 79860, 1974 - based on the principle associations); cleaning the soles of workshop shoes (energy resource), repairing the blueprint machine (principle homogeneity), automatic effluent sampler (a.c. 559 151, 1977; A.N. Orlov - energy resource), block alignment in a pipe (A.G. Mokov), pressure transfer of hot harmful solution (A. Zakirov, 1973 - resource supersystems), polluting the air with vapours. In p / o Uralhalogen: obtaining aluminum bromide (V. Fomin, ac 316654, 1970; 387932, 1973 - according to the principles crushing, mediating and combining).

One of the 40 techniques for resolving technical contradictions in tasks - local quality principle used in many inventions, such as: chemical metallization - acceleration by heating the reaction NiSO 4 + NaH 2 PO 2 \u003d (t) => Ni (h) + NaH 2 PO 4

In a cold solution flow - (a.s. 186246); obtaining PtF 6 - (US Pat. RF 1419069), MoF 5 - (US Pat. RF 1760642, 1999) by the action of cold fluorine gas on hot metals; reagent- intermediary(synthesis of pentafluorochlorine from trifluorochlorine, cesium fluoride and fluorine - (US Pat. 290530, 1970)

Emulsification of milk (contradiction: the pipe with milk must be long and short, and the contact of milk with air must be excluded - allowed division in time and space), peeling tomatoes - the difficulties of such cleaning are resolved with the help of physical effect(dip tomatoes in a gelatin solution of a ferromagnetic colloid, dry with steam, pass through a magnet, which will remove the shell using a ferromagnet, clean the magnet with a scraper), polymer tape (dries poorly in an air dryer - dry with a melt according to the principle changes in the state of aggregation; the semi-liquid polymer has time to flow to the bottom side during the hardening of the horizontal tape - to withstand vertically until hardening - based on the principle transition to another dimension) (Inteko, 2006).

3. TRIZ based creative search methods: 4 p.m.

A) The system of 40 techniques for resolving technical contradictions ( TP) and Altshuller’s HS table (the main tool for finding solutions in Western countries, firms and universities [Algorithm of invention - M.: 1973; 40 Principles TRIZ Keys - Worcester, MA, 1997]) - a selection of examples in technical solutions for ecology and environmental protection - [ AT. Mikhailov Vestnik TO REA - Kazan, 2005, 3, p.19-20; 2006, 3, pp. 17-18]), etc.);

B) combinations of techniques for resolving technical contradictions using physical, chemical and geometric effects in solving problems - system 76 standards solving inventive problems [G. Altshuller // Sat. A thread in a labyrinth - 1988, p.165-230] - taking into account the laws of technology development (ZRTS);

D) GS Altshuller bequeathed to us invention algorithm ARIZ-85v for solving complex, non-standard problems [Find an idea - 1986, 1991 and 2003, p.186-206; 2007, pp.237-274; Sat. Rules of the game without rules - 1989, pp. 11-50, etc.], using all the means of TRIZ: 10 RTS laws (structure and completeness of the TS parts, energy conductivity in the TS, coordination-mismatch of the actions of the TS elements; development of the TS towards the ideal TS - by optimizing the use of resources, the heterogeneity of the development of parts of the TS and the emergence of technical contradictions (TC), identifying the physical causes of contradictions as a FP (macro- and micro-FP); the transition of the TS from development in S to changes in the NS; changes in the TS through changes to micro -level - by changing and applying physical and/or chemical effects, increasing the degree of "su-field" of the TS [Coll. DFT - 1987, p.67-74; Thread in the labyrinth-1988, p.95-163, etc.].

Examples of ARIZ-85v applications: lightning rod for a radio telescope antenna (contradiction: the antenna is necessary and harmful); the task of transporting liquid slag (MI Sharapov, MMK. A.S. 400621 - a cover is necessary and harmful); model in a water stream (YuT-1981, 11, p.12) - for long-term observations, a lot of paint is needed, in order not to distort observations, little paint should be applied to the model; electrodeposition Me(OH)n from kerosene- according to principle associations(RUZPOTRIZ-1992, p.56-58) to simplify the hydroxide isolation scheme:

(Me(TBPh)n)(sint) + HCl/NH 4 Cl + K - (katod) =(Pel)=> (Me(OH)n)(oc)/Katod + H 2,

Auto sampler– use of energy resource (RUZ according to TRIZ-1992, pp. 51-54) to resolve TP: sampler hole e.b. small (to select a given aliquot) and large (so as not to be clogged with precipitation); obtaining ethylene oxide - according to the principle of dynamism, in order to resolve the contradiction: at a high rate of supply of reagents, the system overheats: 2 C 2 H 4 + O 2 = (kataliz) => C 2 H 4 O + Q (superthermal kataliz);

Broadcast hot solution- use of the supersystem resource (p.82-83) - displacement of water vapor pressure instead of air.

Database on the use of physical and chemical effects in IM-1.5 (30 chemical effects and 300 patents), IM-Phenomenon, TOP-2.5 (60 chemical effects and 175 chemical patents).

E) forecasting development of technical systems (TS lifeline, 8 RTS Laws, lines of fragmentation, dynamism, controllability; activation of reactions); forecasts of possible emergencies and ways to prevent them (“sabotage” method of B. Zlotin - now in the USA; and also instead of how to explain - “how to do”); combining alternative systems (S. Litvin (USA), V. Gerasimov) and the best properties of such systems (A. Pinyaev, USA).

The line of development of the activation of chemical reactions: heating and the principle of local quality (temperature), the principle of an intermediary, activation at low temperatures by an electric field or UV light, catalysis, resonance activation of reagents (including enzymatic catalysis).

G) functional-cost analysis (L. Miles, Yu. Sobolev; N. Moiseeva; S. Litvin and V. Gerasimov), Issikava-Sibiryakov diagram - as a means and means of identifying tasks and problems that need to be resolved; algorithm for selecting a problem from an inventive situation (G.I. Ivanova) - before solving a technical problem, it is necessary to accurately identify the source, the place of its occurrence.

H) About finding solutions scientific tasks (explaining the Russell effect - the effect of a polished silicon surface on a photographic plate; and overvoltages during hydrogen evolution on cathodes made of different materials by V.V. Mitrofanov, St. Petersburg); replacing the explanation of the phenomenon with the search for an answer to the question: “how to do this?”.

A database on the use of more than 100 varieties of chemical effects has been proposed. identified in solving creative problems in 1200 patents and creative solutions in chemistry and ecology. Further development and expansion of the database of patents in chemistry and ecology will lead to the expansion of the currently proposed list of types of chemical effects, which will make it possible to take into account in more detail and more fully to every engineer achieve world experience inventors. Material is also being prepared for a more detailed description of the proposed chemical effects with an illustration of their actions in specific technical solutions. It is necessary to expand the capabilities of the search system to select the required chemical effect in connection with the identified physical contradiction of the technical system or task, since while the transition from contradiction to choice, the search for the effect occurs either by chance or on the basis of the limitations of the psychological inertia of specialists.

7. prospects TRIZ in theory and practice, testament of G. Altshuller 2 hours.

Shall we wait for the EVIDENCE of the benefits of TRIZ for Russian enterprises from abroad (the last 15-17 years have already shown the widespread use of TRIZ there, even if so far mainly in the form of applications by most engineers of G. Altshuller's table - we have had such an approach in 70 years of the 20th century)? Or will the management of our p/o decide that it is necessary to involve their engineers in solving creative problems based on the full use of the entire arsenal of problem solving tools accumulated in TRIZ? To this end, it is necessary to constantly acquaint software engineers with both the world experience in applying TRIZ in production, and with the accumulated experience in this software. One should not expect an immediate result from the knowledge of TRIZ by engineers, because they have been taught all their lives not to be creative, but to be only executors of the instructions of the leaders - life and practice show that the instructions of the most active and creative bosses are not always indisputable - they are not always based on knowledge of the laws of development of technical systems, on which TRIZ is based.

You can also involve specialists from TRIZ-professional groups, such as GI Ivanova from Angarsk, AV Podkatilina from Moscow (both have extensive experience in solving creative problems in the defense and chemical industries). I regret that at one time the leadership of the Mayak p / o did not respond to my call: to involve my best student of the Academy of Sciences Orlov (a resident of Ozersk) in solving creative problems in the p / o.

It is also necessary to acquaint teachers of secondary schools and Houses of children's creativity with the experience of using TRIZ, accumulated in secondary schools and Houses of creativity in different cities of Russia - this experience is known in Chelyabinsk, where pedagogical conferences on TRIZ pedagogy are held annually, as well as in Saratov, Ulyanovsk and at conferences MA TRIZ. Somehow, introductory classes on TRIZ were held at the Ozersk TI (a branch of MEPhI) in the 70-80s, I think it is necessary to resume and conduct such classes on a regular basis.

The total amount of classes: lectures 16 hours, practice 24 hours,

Home training 100 hours, counseling 8 - 16 hours, defense 6 hours.

TOTAL: 56 (or 64) hours

TRIZ method (theory of inventive problem solving) in teaching chemistry

Currently, there are a lot of different technologies in pedagogy that help to present material to students in a more accessible form. For the development of cognitive activity in the field of chemistry, TRIZ technology (Theory of Inventive Problem Solving) can be used. This technology is aimed at developing children's natural abilities, and also provides an opportunity to prove themselves, to win the respect of classmates.

There is a Russian proverb “Everything new is a well-forgotten old”. This applies to TRIZ technology, since work on TRIZ was started by G. S. Altshuller and his colleagues as early as 1946. The first publication - in 1956 - is a technology of creativity based on the idea that "inventive creativity is associated with a change in technology that develops according to certain laws" and that "the creation of new means of labor must, regardless of the subjective attitude to this, obey objective laws ".

The main functions and areas of application of TRIZ are: Solving inventive problems of any complexity and direction; Awakening, training and competent use of a person's natural abilities in inventive activity (primarily figurative imagination and system thinking).

The purpose of this technology: "Knows, understands, applies"

TRIZ breaks the material into fragments. The process becomes modular. There are three basic principles of TRIZ: - The principle of objective laws. All systems develop according to certain laws. They can be known and used to transform the world around. - The principle of contradiction. All systems develop through overcoming contradictions. - The principle of specificity. The specific solution to the problem depends on the specific resources that are available.

Didactic possibilities of TRIZ: - solution of creative problems of any complexity and orientation; - solution of scientific and research problems; - systematization of knowledge in any field of activity; - development of creative imagination and thinking; - development of the qualities of a creative personality and the formation of key competencies of students: cognitive, creative, communicative, worldview; - development of creative teams.

As examples, several tasks can be presented, as well as several techniques of this technology. 1. At the beginning of the last century, the German chemist Christian Schönbein invented a new sympathetic ink, which is a solution of manganese sulfate. After drying, the text written by them on pink paper becomes completely invisible. Proud of his fiction, Schoenbein wrote a letter in his own ink to the English physicist and chemist Michael Faraday. History is silent about whether Faraday managed to read the message of his German colleague. Question. Think about how you could show what was written?

2. Why do houseplants planted in a metal can often grow better than the same plants in clay pots?

3. To increase the octane number of gasoline, an antiknock additive is used - tetraethyl lead. This is a very toxic substance that can be present in gasoline vapors, which means it can get into the air. This is especially dangerous in motor transport enterprises. Suggest a method for detecting tetraethyl lead vapors in the air.

Fairy tale An alchemist sits by a candle, his daughter comes up to him and asks: “Dad, what are you doing?” "I want to get a jewel, daughter." - "From this candle?" “No, from a candlestick,” the father replies. He waited until the black scale appeared on the candlestick, scraped it off and threw it into the acid - a blue solution became; threw a pinch of soda - a greenish precipitate fell out; added caustic alkali - and the sediment inside became completely blue. He dried this mixture, and a paint of wondrous beauty came out. Why not a gem?

2. Why do stars burn? Stars and our Sun consist of a mixture of two gases, the transformation of one of them into another occurs with the release of light and heat. What are these gases? The elements included in the composition are neighbors on the periodic table; the first of the gases is twice as light as the second, the molecules of the first gas are diatomic, the second are monatomic, moreover, the second gas is inert. Name these gases.

Cases, riddles, etc. can be used as techniques of this technology. 1. Explain the chemical processes mentioned in the lines of A. Akhmatova's poem. “On my washstand Copper turned green. But the ray plays on him so much, What fun to look at.

2. Trees, bushes, wires seem to be dressed in lace. And it seems like a fairy tale, But in essence - only .......

Who and when was the first to synthesize water? Which air is heavier - dry or humid? -- Which human organ contains the largest amount of water, and which contains the least? -- Name eight names of the state of water accepted in meteorology. How many water molecules are in the ocean? - What are snowflakes? - Do its own molecules break up into ions in water? - Can water burn? - Can water flow upwards? -- List the chemical and physical properties of water. - The role of water in human life.

Riddles about chemical elements. It has long been known to man: it is viscous and red, Even in the Bronze Age It is familiar to everyone in alloys. Explain its properties in terms of chemistry.

As you inhale the green gas, you will be poisoned now. Who discovered chlorine? Where is it applied? How does it affect the body?

I am a luminiferous element, I will light a match for you at the moment. They will burn me - and under water my oxide will become acid. What are the properties of phosphorus? Where is it applied? What allotropy modifications do you know? Explain the mechanism of luminescence.

Modern enterprises, institutions, firms are looking for creative people who are able to give non-standard solutions to various problems, who are able to solve creative problems. In front of a modern school, within the framework of the “Concept for the Modernization of Russian Education”, the main goal of a general education school is formulated - to form an integral system of universal knowledge and skills, the experience of independent activity and personal responsibility of students ... at the same time, it is important to ensure the right of each student to individual development.

"Of course, scientific truth
will always find its way into life,
but make this way faster and more
directly depends on people, and not on the truth ”(P. L. Kapitsa)

The modern world is dynamic. We often see how a new, barely managed to appear, turns into history.
Even in ancient times, it was known that mental activity contributes to both better memorization and deeper insight into the essence of processes, objects and phenomena. So a characteristic feature of Socrates was the formulation of problematic questions to the interlocutor. The same technique was known in the Pythagorean school.
In modern history, the desire for active learning goes back to the philosophical views of F. Bacon, who was critical of the truths of verbal origin and demanded the truth obtained through the study of reality. In the future, the idea of ​​active learning was developed by such teachers and philosophers as Ya. A. Komensky, J.-J. Rousseau.
In our country, the idea of ​​developmental education was first put forward by L. S. Vygotsky.
According to L. S. Vygotsky, creativity is the norm of child development, a tendency to creativity is generally inherent in any child.
The internal need for creative activity is considered by psychologists and educators as an objective pattern of personality development.
According to the research of I. Ya. Sukhomlinsky, teaching creativity is equipping students with the ability to recognize the problem outlined by the teacher, and later to formulate it themselves. This is the development of the ability to put forward hypotheses and correlate them with the conditions of the problem, to carry out a phased or final verification of the solution in several ways; abilities to transfer knowledge and actions to a non-standard situation or create a new way of acting.
The Theory of Inventive Problem Solving (hereinafter: TRIZ) - pedagogy, as a scientific and pedagogical direction, was formed in our country in the late 80s. It was based on the theory of inventive problem solving (TRIZ) of the national school
G.S. Altshuler. TRIZ is a certain sequence of actions and various methods of the educational process, such as brainstorming, synectics, morphological analysis, the method of focal objects, used taking into account active thinking and educating a creative person, to solve complex problems in various fields of activity.
Initially, TRIZ was used only to solve engineering and technical problems, but has long since become a universal technology for analyzing and solving problems in various areas of human activity.
In the lessons using TRIZ, knowledge, skills and abilities are not transmitted from the teacher to the children, but are formed as a result of independent work with information.
“It must be admitted that learning based on the assimilation of specific facts has become obsolete in principle, because the facts quickly become obsolete, and their volume tends to infinity.” These words of A. Gin made me look for new methods of work.
So I got acquainted with TRIZ - Technology for Inventive Problem Solving.
In the lessons using TRIZ, knowledge, skills and abilities are not transmitted from the teacher to the children, but are formed as a result of independent work with information.
In my lessons I use different types of creative tasks.
The creative challenge is:
- with fuzzy conditions;
- containing a contradiction;
- allowing different solutions;
- having multiple answers.
The most interesting among creative tasks are inventive and research tasks.
Inventive problem - contains a problem that needs to be solved, and obvious solutions are not applicable under the given conditions. Before the decisive question is: "How to be?"
For example: cubs do not see well and do not immediately recognize their mother returning from hunting. Waiting for it to approach is dangerous, but what if it is someone else's adult bear. He can offend. How to be cubs?
Research task - includes a certain phenomenon that needs to be explained, to identify the causes or to predict the result. The decisive question is: “Why? How is it happening?
For example: when going hunting, a she-bear leaves her cubs alone. And when she returns, the cubs behave very strangely: as soon as they see the approaching mother, they climb thin trees. Why?
Children need to be taught how to solve creative problems. It is necessary to introduce students to the TRIZ tools: contradiction, system operator, ideal end result, resources, techniques, solution algorithm, etc. It is advisable to do this in optional classes. If this is not possible, then on specific tasks it is necessary to gradually introduce the children to the “thinking tools” of TRIZ during the lessons. You can, of course, solve problems by trial and error, but this is ineffective. Knowledge of TRIZ tools allows solving problems consciously and quickly.
Students solve problems in brainstorming mode. You can use different modifications of this technology: "free swimming", "blind attack", "visual assault". This active form of work allows you to develop a creative style of thinking in children. The search for answers arouses great cognitive interest and positive emotions in the children.
I solve problems with students of different age groups. It is interesting when high school and middle school students solve the same problem. Their solutions and answers are often different.
Triz tasks can be applied at different stages of the lesson, it depends on the purpose of the lesson.
The children really like to come up with tasks for their classmates on their own. Moreover, the problem can be made from any interesting fact. First, the guys and I learn how to prepare small messages on the topic “Did you know that ...”, and then we turn these messages into tasks.
TEXT. Amphibians are common on all continents except Antarctica, and, as a rule, live in close proximity to water bodies or in very humid tropical habitats.
Task. Although amphibians live in a variety of environmental conditions, their distribution is always associated with specific living conditions - this is warmth, presence, and significant air humidity. Why are frogs not found in deserts, but "attached" to water bodies? The hint is contained in the textbook (Sonin N.I., Zakharov V.B. Biology. Diversity of living organisms. M .: Drofa, 2000. S. 188, 190.)
Text. Everyone has probably seen this forest blacksmith, and if you haven’t seen it, then you must have heard it. The sound of a woodpecker is heard almost in any forest. And if a woodpecker knocks, it means that the trees heal ... The woodpecker knocks, drumming all day, but what about the head? Doesn't it hurt?
Task. American scientists are interested in how he manages to beat his head against a tree without harming his health all his life?
In the section "Metals of the main subgroups of 1-3 groups of the Periodic Table of chemical elements of D. I. Mendeleev" when studying the topic: Aluminum, I propose to solve the problem of the following content:
A certain craftsman brought the Roman emperor Tiberius (42 BC) a bowl made of metal resembling silver. The gift cost the inventor his life: Tiberius ordered to execute him and destroy the workshop, because he was afraid that the new metal would devalue the silver of the imperial treasury.
You can use this technology when working with gifted children, with children who are passionate about biology and just in the classroom to make them more interesting, dynamic, and cognitive.
In one of his works, Yu. G. Tamberg said: “If a person knows how to solve problems well, then he thinks well.”
It is difficult, but interesting, to teach to think outside the box, to overcome the stereotyped mind, to manage the process of thinking.
The teacher, having "in his hands" an interesting factual example, can construct from it creative task necessary complexity in accordance with the goals and objectives of the lesson. The source for constructing problems in chemistry is the book by Lyudmila Alikberova "Entertaining tasks in chemistry." Here are some interesting questions that you can ask students and then build creative research tasks:
1. On the doors of some chemical laboratories there is an inscription: “Do not extinguish with water!” How can you extinguish a fire in such laboratories?
2. Why does a person become addicted to this substance already from the second or third dose of heroin?
From these cognitive questions, with using TRIZ technology to design a number of creative tasks. For construction research tasks we use the following algorithm:
- initial fact;
- task formulation;
- detection of contradiction;
- search for resources.
- the formulation of the ideal end result.
Example 1 Initial fact: in India, there is a column on the square, which was made about 1500 years ago from iron. For many years it has not been subject to corrosion, despite the humid and warm climate.
Let's compose the text of the research problem: As you know, the climate in India is warm and humid. On the square in the courtyard of the mosque in Delhi are the famous iron column - one of the wonders of the world. Why is the iron column in India standing for almost 16 centuries without collapsing? How did the ancient masters manage to create chemically pure iron, which is difficult to obtain even in modern electrolytic furnaces?
Reveal contradiction between knowing that iron can break down (rust) and not knowing how to protect against corrosion.
Hypotheses:
If an anti-corrosion agent is introduced into the iron composition of the column, the column will not rust;
If the column is absolutely smooth, then moisture does not settle on it and no galvanic couple is formed that contributes to destruction;
If the alloy of the column contains substances that, reacting with iron, water and oxygen, created a protective layer.
Search for Resources with the help of additional literature and the Internet.
Result: the column contains an unexpectedly large amount of phosphorus, which, reacting with iron, water, oxygen, created a kind of protective anti-corrosion surface layer.
Social creativity is impossible without such a method of activating creative thinking as brainstorming. The brainstorming method is an operational method of solving a problem based on stimulating creative activity, in which the participants in the discussion are asked to express as many solutions as possible, including the most fantastic ones. Then, from the total number of ideas expressed, the most successful ones are selected that can be used in practice. Alex Osborne (USA) is considered to be the inventor of the brainstorming method.
Brainstorming includes three required steps
- Formulation of the problem. Preliminary stage. At the beginning of this stage, the problem should be clearly formulated. There is a selection of participants in the assault, the definition of a leader and the distribution of other roles of participants depending on the problem posed and the chosen method of conducting the assault.
- Generation of ideas. The main stage, on which the success of the entire brainstorming largely depends. Therefore, it is very important to follow the rules for this stage:
- the main thing is the number of ideas, do not make any restrictions;
- a complete ban on criticism and any assessment of the ideas expressed, since the assessment distracts from the main task and knocks down the creative mood;
- unusual ideas are welcome;
- combine and improve any ideas.
- Grouping, selection and evaluation of ideas. This stage allows you to highlight the most valuable ideas and give the final result of the brainstorming. At this stage, unlike the second, the assessment is not limited, but, on the contrary, is welcomed. Methods for analyzing and evaluating ideas can be very different. The success of this stage directly depends on how “equally” the participants understand the criteria for selecting and evaluating ideas.
Example 2: Statement of the problem: Previously, fruit was packed into boxes and boxes by hand, but now it is done by a machine. The conveyor brings the empty box to the table. Fruit rolls down the tray. An electric motor makes the table vibrate so that the fruits fit more tightly. A wonderful car, but ... It has a drawback: falling into a box, fruits hit each other and deteriorate from this.
Generation of ideas:
- You can lower the fruit-rolling tray directly to the bottom of the box.
- You can stack different fruits according to their softness. For example, oranges and peaches.
- There should be something soft between the fruits.
- You can put soft balls between the fruits, they will soften the blows.
- And what about the balloons when the box is full? Why not transfer them manually?
- Insert magnets into the balls!
Selection of ideas. When stacking fruit, you must use the principle of "intermediary". This will be a soft ball. Embed a magnet in them, and when the box with fruits and balls is full, turn on the electromagnet, which is located above the box, the balls “jump” out of the box
The next step is to analyze the solutions i.e. write out in a table those information of school subjects that were useful for solving, and then write out in another table all the inventive techniques used to solve these problems.
To analyze the emergence of new techniques for children "principle of crushing" and "principle of mediator".

inventive techniques
Formulation in solving the problem, including the use of the technique	Name of admission to TRIZ	His essence (formulation in TRIZ)
"Fruit stacking" (...between two colliding fruits there must be a third substance that looks like a fruit)	Principle of homogeneity	Objects interacting with this object must be made of the same material (or similar properties)
“Packing fruits” (... a magnetic plate is built into the ball. An electromagnet is placed above the box. When the box is full, turn on the electric light, and the balls “jump” out of the box	Replacing the mechanical circuit	A) replace the mechanical circuit with optical, acoustic, etc.4 B) use to interact with field objects; C) use fields in combination with ferromagnetic particles
“Laying fruit” (... between two colliding fruits there should be a third substance similar to a fruit. Let's throw two dozen balls into the box, for example, from polyurethane, they will soften the blows)	The "intermediary" principle	A) use an intermediate object that transfers or transfers an action; B) temporarily attach another (easily removed) object to the object

Applying TRIZ technology during lessons, I get an increase in learning motivation, the development of non-standard thinking of students, and the socialization of the individual.

MBOU secondary school No. 47, chemistry teacher

Modern enterprises, institutions, firms are looking for creative people who are able to give non-standard solutions to various problems, who are able to solve creative problems. Therefore, in front of a modern school, within the framework of the "Concept for the Modernization of Russian Education", the main goal of a general education school is formulated - to form an integral system of universal knowledge and skills, the experience of independent activity and personal responsibility of students ... at the same time, it is important to ensure the right of each student to individual development, which does not contradicts his natural abilities, inclinations, interests and create good conditions for learning, development, health of a student with different abilities.

To solve the problem in my lessons, I use elements of an adaptive learning system and the TRIZ method (the theory of inventive problem solving, author G.S. Altshuller). Let's consider these. The structure of a creative lesson differs from the traditional one and includes the following blocks:

1. 
   Motivation
2. 
   Content
3. 
   Puzzle
4. 
   Reflection

All teachers have one goal - to teach, develop, educate. But we often encounter that children have no desire to learn. The question arises how to overcome this contradiction. Let's turn to human psychology. The child is born an explorer. Bogoyavlenskaya D.B. on the basis of experimental data, she concluded that the formation of creative abilities does not go linearly, but has two peaks in its development: the most striking burst of their manifestation is noted by the 3rd grade (age 10 years), and the second falls on adolescence. It is at the age of 14-15 (grade 8) that students first begin to study chemistry, therefore, properly organized activities of students in the chemistry lesson and after school hours will contribute to the development of creativity at this age.

A person enjoys any action if he performs it on his own. In this part of the lesson, he encounters something that strikes his imagination and arouses curiosity. For this, TRIZ methods can be used: two step puzzle

Riddle answer (aluminum)

What does it look like?

What is the difference?

sodium

Not coated with an oxide film, active

magnesium

Reacts with oxygen at room temperature
Metal, 3rd period

A white, silvery metal, but not sodium, burns with a dazzling flame, but not magnesium, an element of group 3, but not boron, interacts with alkalis, but not acid. A similar task can be given at the beginning of the lesson, to determine the topic of the lesson, or as homework, in
