Relations of didactics of physics and projects of education in physics

Deepening interest in didactical problems of teaching physics can be from the beginning associated with the creation of the subject of physics, especially at secondary schools. In the 20^th century it was no longer possible to ignore the rapid development of physical science and application of its results in practice. The subject of physics required the definition of its content, development of textbooks and, amongst others, new ways of teaching in comparison with the past. The interest of teachers focused mainly on increasing the clarity of explanation - the creation of experiments and teaching aids. Since 1926 Association of Mathematicians and Physicists in the first Czechoslovak Republic issued a didactic-methodological annex to the Journal of Mathematics and Physics, as a discussion in order to increase the quality of teaching. However, this action was spontaneous and subjective. In the second half of the 20^th century didactics of physics became a study discipline, part of the training of future secondary school teachers and the development of scientific work in the field of Theory of teaching physics started.
