The role of research tasks in teaching physics

The aim of the study is to prove the relevance of research tasks in teaching physics on the example of the "black box". The ability to use basic formulas, to know the units of measure and their ability to influence logical and abstract thinking is improving students' knowledge during the Physics Olympiad. Algorithms and necessary instructions are used to calculate the tasks. The period of application of knowledge in practice has a leading place in the learning process because comprehensive activities of pupils in the execution of tasks are carried out through a great mental work. The Olympiad tasks allow to use creativity and thus expand the scope of their application. It is necessary to take into account that students cannot do without realistic mental activities on the basis of the analysis of the theoretical and practical skills required for the release of the Olympiad tasks. Solving the experimental tasks it is necessary to choose the theoretical proof, the method of its solution and evaluate the process of measurements, estimate the errors and analysis of received results.
