Ten years ago we started to develop a Collection of Fully Solved Problems aimed at introductory
undergraduate and high school level students. The collection is specially designed to encourage
students in an active approach to problem solving, e.g. to solve at least some parts of a problem on
their own. Nowadays the Collection contains about 800 fully solved problems in physics in Czech and
nearly 180 problems in English. It has several hundreds of unique visitors per school day. Based on
user feedback, the collection is used by students mainly for their home study and by teachers as a
supplementary material. The creation of the structured solution of the physics problems has proved
to be a beneficial activity for prospective physics teachers (students of our department).
