Abstract
Two Czech high schools participated in a survey focused on solving physics tasks in mechanics. First and second year students (students at the age of 15 to 17) solved two physics tasks called “Passing of trains” (physicstasks.eu – tasks number 228 and 229).
At first, students solved the tasks independently as a homework; afterwards, they solved the same tasks in a class (group work) and in the last stage, they compared their solutions with the electronic collection of solved tasks (physicstasks.eu). After this part of the study, students filled out a short questionnaire with open format questions, where they described the main advantages and disadvantages of each of the three stages in the solving process.
They also compared this style of solving tasks with the conventional method of teaching.
