EDUCATIONAL AND COGNITIVE PROJECT “FROM A VACUUM DIODE TO A MICROWAVE OVEN MAGNETRON”, IMPLEMENTED WITHIN THE FRAMEWORK OF THE PROJECT-BASED LEARNING CONCEPT

Abstract

In the article, the authors offer a specific example of an educational and cognitive project developed for high school students and implemented while studying a physics course. The project combines a step-by-step study of theoretical material on the principle of “from simple to complex” and the application of the knowledge gained to explain the operation of various technical devices, from simple vacuum diodes to a magnetron of ultra-high-frequency cookers, commonly referred to as microwave ovens. The practical orientation of the project is due to the fact that students are able to explain the physical principles of the devices on the basis of knowledge gained in the school curriculum with a little additional information about the technical design of the devices obtained with the help of additional sources. The proposed approach helps to bridge the “gap” between the topics of school physics and the understanding of the principles of modern devices. The results of the study can be useful as methodological recommendations for teachers who practice the project method in teaching.
