Additional information "Vikladannya chemistry in technikum according to professional programs"
Chemistry, which is one of the most important disciplines of the natural sciences and science cycle, is of great importance for the development and education of high-quality robots and faculties of the middle Lanka.
The role of chemistry in the system professional education is twofold. From one side, won є one of the main disciplines, scho lay the basis home coverage, From the side, the chemistry in the meaning of the world is pouring into professional training Maybutnyh robots and fahivtsiv.
When training scientists for the professional "Veterinary paramedic", "Kuhar - confectioner", for the specialty "Mechanism Silskoy government»In the technical course of the chemistry course.
When developing robotic programs, the best in a rational way profіluvannya є combinations. Yogo the essence of the field is in the fact that, with the introduction of these conditions, it is important to understand the importance of maybutnoy profession abo specialties. There is no need to discuss the food in detail, the professionally significant material is seen in the "modular" distribution, which will complete the course of chemistry, and when the child is invited to complete the report, look at the nutrition of the chemistry professionals, With a seryozna uvaga, come to vivchennya in pour tsikh spoluk on navkolishnє centerі organism of people і creatures.
In the case of the vivchenny block "Chemistry in the Silskoy Gospodarstva", during the preparation of students for the specialty "Mechanization of the Silskoy Gospodarstva" short characteristic a special section of chemistry - agrochemistry, filed with information about good chemistry and roles chemical elements in the life of roslin and tvarin.
When preparing veterinary paramedics, there is a great respect for the role of chemistry in creation. A characteristic is given of deyakyh z'єdnan, which allow to improve the productivity of the product, such as bіlkovo-vitamins additives. It is possible to give a general characteristic of the way, how to enter the feed store for silky-diversified creatures, to see and see feeds, as well as the characteristics of additives, which to increase the quality of feeds.
When vivchenny blocks "Fundamentals organic chemistry"І" Zagalna chemistry "in addition to those included professionally meaningful food, which illustrates the history of outlandish chemistry laws for understanding the foundations of this profession and specialty.
So, with the introduction of themes from the home chemistry "Dispersion systems", "Rozchini", from the organic chemistry of such topics as "monoatomic and rich in alcohol", "Phenols", "Aldegidi", "Carboxylic acids", "Carbohydrates", "Bilky to take into account the value of the material in the preparation and preparation of medicinal preparations.
The science of pharmacology is still closely tied to chemistry. Have your pedagogical practice vicorist conduct of binar lessons (chemistry-pharmacology). Basic principles of a binary lesson:
Professional straightness - zmist initial material I can professionally direct it on the basis of interconnection of pre-dietary nutrition (chemistry and pharmacology);
Polytechnic - learning to focus on the acquisition of theoretical knowledge in the field of virtue.
When preparing biennial lessons, it is necessary to know how the structure of the lesson is guilty of representing the logical message of the beginning, the role of the lesson in zagaln_y systems... Required tight connection mіzh structural elements lesson. As an application to serve as carrying out a binary lesson on the topic: "Glucose".
For robots who are engaged in the field of food production and processing of chemical spoluks and grubs in the United States, it is of great importance for food, tied with chemicals in carbohydrates, fat, bilkiv. The stench is the basis of the їzhі, as well as inorganic spoluks If you go in to the warehouse, or to know the food when processing the food, you can cook it or eat it for polishing the quality of food products.
The whole module can be stored in 5 topics: chemistry warehouse"," The role of bolsheviks, fats, carbohydrates in the consumption of people "," Organizational speeches, how to become stagnant for the development of the living authorities of the people "," inorganic speeches, Vikoristovuvani in the food industry for polishing the quality of food products "," Kharchova industry and problems of ecology ".
In my pedagogical practice, I give great respect to the revolt of the young people with the professional wizard. As a matter of fact, the solution of tasks is price practical sucking theoretical material, supplements of scientific knowledge in practice. In another way, solving problems is an excellent way of communicating between subject and course links, as well as connecting chemistry science with life. The model of the problematic situation, the development of certain needs, based on the knowledge of laws, theory and methods of chemistry, based on knowledge, development
when folded robotic programs profiled course chemistry obov'yazkovo vrakhovoy conducting laboratory-practical robots, integrated with robots for the professional cycle. The application is to serve as a test of laboratory robots for preparing designs. The topic is to be taught at the lessons of "Pharmacology" at the veterinary education.
Development of professional chemistry courses for professionals chief pledges In the absence of any (middle) foreign education in the field of positive motivations in the process of living chemistry, as such courses visibly and reliably show the role and knowledge of chemistry knowledge in the future of practical learning
