CREATING AND USING VIRTUAL LABORATORY
TO ENHANCE STUDENTS THINKING
IN A CHEMISTRY LESSON AT SECONDARY SCHOOL
Abstract: this article discusses the features of the development of modern methods in teaching chemistry and laboratory work. A cross and comparative analysis of the influence of the choice of the direction of development of chemical education was carried out. Recommendations are given for the implementation of developments in the development of technologies.
Keywords: analysis, method, research, chemistry, education.
Glass equipment is often used in the experiments. Every time in a lesson, there is a risk that the test tube will break, harming the student. In the Virtual Laboratory "Inorganic Chemistry" the supply of test tubes is unlimited. But we should not forget that the laboratories are representative, the research results correspond to the real ones, which means that the test tubes can still “break” during the experiment if safety precautions are violated. However, you should not be afraid, virtual glass is not capable of harming a person.
The virtual laboratory allows you to plunge into the school curriculum of the course of inorganic chemistry. Using several dozen reagents, you will be able to conduct experiments included in the program of the 8th and 9th grades.
Work with reagents as you would in a lesson. A wide range of instruments will help you.
Virtual Chemistry Laboratory is a series of interactive practical works and experiments. The subjects of the experiments are fully consistent with the EXAMPLE PROGRAM OF BASIC GENERAL EDUCATION IN CHEMISTRY and are focused on chemistry textbooks recommended by the Ministry of Science and Education of the Russian Federation and used in most Russian schools. The manual presents works on the study of physical and chemical properties, the production and use of metals and non-metals, their compounds.
Experiments are proposed to familiarize with samples of simple and complex substances, minerals and ores, to study the physical and chemical properties of some of them. The information contained can be used in the study of the topics "ELEMENTARY FOUNDATIONS OF INORGANIC CHEMISTRY", "INITIAL CONCEPTS ABOUT ORGANIC SUBSTANCES", "CHEMISTRY AND LIFE".
Thus, a virtual chemical experiment is a kind of educational experiment in chemistry; its main difference from natural is the fact that computer technology serves as a means of demonstrating or modeling chemical processes and phenomena [1, p. 91], when performing it, the student operates with images of substances and equipment components that reproduce the appearance and functions of real objects, that is uses a virtual laboratory. We understand a virtual laboratory in teaching chemistry as a computer simulation of an educational chemical laboratory, realizing its main function - conducting a chemical experiment for educational purposes. Technically, the functioning of the virtual laboratory is provided by software and hardware of computer technology, a didactically - meaningfully and methodically substantiated system of assumptions about the course of the studied chemical process or manifestations of the properties of a chemical object, on the basis of which one of the possible options for the reaction of the virtual laboratory to the user's actions is developed. A virtual laboratory acts as an element of a high-tech information educational environment, being a means of creating and performing a virtual experiment. Virtual laboratory work in chemistry is a virtual chemical experiment in the form of a set of experiments united by the common goal of studying a chemical object or process.
The creation of a virtual laboratory work consists of the stages of setting goals for laboratory work, choosing a virtual laboratory, identifying the capabilities of a virtual simulator, correcting goals, determining meaningful and didactic tasks, writing a scenario, testing, evaluating and analyzing the reliability of the process and the result of a virtual experiment compared to a natural one, correction scenario and drawing up methodological recommendations.
The goal-setting stage implies the process of choosing the goals of the planned laboratory work with the establishment of the limits of permissible deviations to achieve the educational result by the most effective and acceptable means, taking into account the material, technical, time, human resources, as well as the personal and age characteristics of students. In our example, the goal was to prepare solutions and study their properties; the work is designed for independent extracurricular educational activities of students. The topic of solutions is covered in most university courses in chemistry, in addition, the skills of preparing and working with solutions are in demand in everyday life and in almost any professional activity.
