Educational experiment in the structure of blended learning technologies

Abstract

In the article, based on the material of physics, the significance of an educational experiment in teaching natural sciences is actualized. The data of the analysis of the evolution of an educational experiment in teaching a school course in physics are presented. A decrease in the share of demonstration and laboratory experiments in educational programs has been noted. The conclusion is made about reducing the requirements for teachers to put an educational experiment at the forefront of all teaching of the subject. The data of the conducted micro-research among future physics teachers revealed their unwillingness to build the teaching of the subject on an experimental basis. The reason for the low level of experimental training of students is the formal approach on the part of teachers and regulatory bodies to the setting of demonstration and laboratory experiments. Optimistic judgments were expressed regarding the demonstration experiments, which, without prejudice to the level of teaching physics, can be replaced by corresponding video recordings. The article presents three options for solving the problem of setting up a laboratory experiment in the implementation of distance and blended physics teaching technologies at school and university. The first option involves conducting experiments on simple home-made equipment. According to the second and third options, in the remote learning mode for conducting educational research, students receive instructions and video recordings of the experiments, as well as materials for processing the measurement results. In the second version, experiments are carried out using software and hardware systems. In the third version, traditional measuring instruments are used. The article provides information on access to experimental materials prepared by the authors of the ongoing pedagogical research.
