The Collection of Solved Problems in Physics and the Collection of Physics Experiments have been developed at the Department of Physics Education, Faculty of Mathematics and Physics, Charles University for more than a decade. Both collections serve as support materials for the students of our department - future physics teachers.
However, their use is much wider. The Collection of Physics Problems is used by not only university students of other study programs and universities, but also by lower and upper secondary school students and their teachers.
The Collection of Physics Experiments is massively used by in-service teachers of both levels of secondary education. Both collections have extensive content (nearly one thousand fully solved problems and more than 160 experiments described in great detail).
Besides the above-mentioned Czech part, both Collections have an English section as well, so they are used internationally. The paper presents not only the methodological approach and content of both collections, but focuses on changes in the use of both collections during distance learning as well.
