NEW WAYS OF HETEROCYCLIC CHEMISTRY TEACHING

Interest of students in natural sciences shows a declining tendency all over the world. Chemistry along with physics belongs to the least popular subjects. Research shows that one of the main causes of this state is the way chemistry is taught at schools. The students´ style of learning is currently changing due to the influence of information and communication technologies. It is thus necessary to seek innovative approaches to teaching chemistry. Using a digital classroom and laboratories is one of such approaches. The present paper describes an interactive relationship of heterocyclic chemistry for lower secondary schools.

Heterocyclic compounds are basic components of both living matter and chemistry of other materials around us. Teaching of heterocyclic compounds is difficult for students on primary and secondary schools. The general educational program of Ministry of Education appeals interdisciplinary approach to chemistry studies. The topic of this paper is heterocyclic chemistry composition in educational process for primary and secondary schools. The goal of the process is barrier elimination among computer, classroom, laboratories and reality. We would like to describe these compounds not only as chemical species, but characterize heterocyclic compounds as biologic components of the live around, laying emphasis on their physiology activity. Next connection indicated the scheme (cooperation of chemistry, physics, mathematics, biology, etc.).

Photosynthesis (for example) is a chain of chemical reactions occurring in chloroplasts (chlorophylls are a typical heterocyclic compounds composed from pyrrole), the microscopic organelles inside the green plant tissue. In the course of the photosynthesis, a plant uses the energy of sunlight and, from the molecules of carbon dioxide and water; it synthesizes glucose (heterocycle), with oxygen being produced as a by-product. Photosynthesis is paramount importance for the life on the Earth because it releases oxygen and produces sugar which, either directly or indirectly, serve as food for the majority of animals. All described processes in computational field (including laboratory) are founding.
