Chemistry is an interesting, but at the same time very complex experimental science. And its role in school, as an experimental science, is to train school children through various forms of work with natural substances and materials. Such experimental activity contributes to the motivation of students to study this subject. The chemical experiment is a specific method of teaching, since it is he who distinguishes the process of learning from the science given to other subjects in the natural science cycle. The use of this form of work makes it possible to better remember the properties of the substances studied, as well as to clarify the essence of the processes that are occurring. But because of the lack of a laboratory, lack of reagents and instruments, laboratory work is very rare. An alternative to these works is the use of a virtual laboratory. Learning activities, in which students can transform their theoretical knowledge into practical ones, can be simulated using a virtual laboratory. Using a virtual lab enables students to repeat any wrong experiment and study it in more detail. The virtual laboratory, in our opinion, has a number of advantages in comparison with traditional laboratory experiments.
1. Experiments using a virtual laboratory are safer (the absence of direct contact with chemical reagents and products of their interaction, this is due to the fact that recently there has been an increase in the number of students with various allergic diseases, very susceptible to various smells).
2. Students can perform experiments that can not be carried out in a real laboratory due to the lack of both chemical reagents and equipment for carrying them out. Also, the use of the CBR allows virtually to study the properties of any substances, including explosive poisonous ones, and to demonstrate the chemical experiment for which reagents are required that are prohibited for use in the school chemical laboratory.
3. Many laboratory experiments require a large amount of time to be spent, and the use of the RDC can solve this problem.
4. One of the problems of the school is the utilization of used chemical reagents, so the virtual laboratory can solve this problem.
5. The CRR allows each student to engage in experimental activities. Virtually conducted experiments allow students, in comparison with the traditional method, to study the process in more detail. The CBR can be used at different stages of the lessons:
- So, at the stage of explaining the new material, as an illustration to the theory;
- at the stage of fixing the material - this is the use of both training tests and simulator programs;
- These resources allow students to work on modeling molecules of inorganic and organic substances.
The use of a virtual laboratory helps the teacher to form the most important chemical concepts, to understand the structure of the atom, molecules, chemical bond.
The virtual laboratory encourages students to experiment and get satisfaction from their own discoveries.
