The article deals with the use of situational tasks while studying chemistry at the basic school and their role in modern education. Notes the value of situational tasks in the development of analytical, intellectual and communicative skills of the students, the ability to find the necessary information in different sources. Analizes the definitions of situational tasks on the basis of which highlights their essential features, shows the structure and describes the requirements for the content of the tasks. The components of the situational tasks are the title, the text, the questions and the tasks. Formulates the requirements for the content of the tasks: description of a real life situation, the availability of the text for the understanding of the students, the presence of inter-subject relationship, the wording of questions of everyday, valeological, environmental and safety regulations. The answers to the questions can be oral or written, containing the formulas of the compounds, the equations of chemical reactions, tables, charts, and suggesting various mental acts – the explanation, analysis, synthesis, generalization, determination of cause-effect relationships. Examples of situational tasks in chemistry for grades 8–9 have been proposed.

CRITERIAL APPROACH TO QUALITY ESTIMATION OF THE SITUATIONAL TASKS IMPLEMENTATION // Pedagogical Review. 2018. Issue 2 (20). P. 131-138

The importance of situational tasks in modern pedagogical education and their role in mastering the content of methodical disciplines is considered. Specific features of the exercises of the first, second and third levels of complexity to the situational tasks in the methodology of chemistry teaching are singled out. The reproductive nature of the activity of the students prevails in the tasks of the first level. They are aimed at the formation of practical skills and abilities in the compilation of didactic materials. Tasks of the second level of complexity have a part-search character of students’ cognitive activity and develop practical skills and abilities in developing methodological materials.

STRUCTURING OF EDUCATIONAL INFORMATION IN THE PRACTICUM ON INORGANIC CHEMISTRY FOR UNIVERSITIES // Pedagogical Review. 2019. Issue 5 (27). P. 19-29

Introduction. In the context of a continuously increasing flow of educational information, there is a contradiction between its large volume and limited time to study. Accordingly, the question arises about the structuring of educational information for laboratory work on inorganic chemistry based on the characteristics of its perception by students. Material and methods. The study was conducted on the basis of determining the effectiveness of the developed instructions for laboratory work in chemistry. It included the results of students’ questioning, determining the difficulty of their perception of instructions in textual and structured forms, estimating the time spent on preparation, execution of work and drawing up a report for them in the experimental and control groups. The groups had the same working conditions and level of training, but their difference was the use of different teaching materials. The results of the input and output control of students’ knowledge in order to identify the quality of the assimilation of chemical information in laboratory classes are given. Results and discussion. The features of the developed instructions for laboratory studies at the university are described, including: presenting them in a table containing individual blocks, algorithmizing the description of actions performed during the experiment, highlighting questions and tasks for experiments. The construction of proposals in the algorithm of the course of the chemical experiment is proposed. An example of the description of the content of experience to the laboratory work is given. The results of the pedagogical experiment are presented, which includes an analysis of the assessment of the difficulty of perceiving instructions of various forms, the cost of study time for preparing and conducting chemical ex periments at work, and testing students in the control and experimental groups. A survey of teachers of chemistry and biology was conducted, the results of which testify to the universality of the presented materials and the possibility of their use in school practice of teaching natural science subjects. Conclusion. The use of structured instructive and methodological materials in conducting laboratory studies in inorganic chemistry helps save study time for preparing and carrying out experiments, on the basis of which the methods of carrying out laboratory work are improved, which allows learners to assimilate chemical information more consciously and qualitatively.
