CALCULATIONS IN CHEMISTRY: PERMANENT PROBLEM OF STUDENTS AND THEIR TEACHERS

Problems requiring calculation at chemistry lessons cause a peculiar difficulty to students. The bibliography concerning the methods of solving calculus problems is very extensive. Several propositions ((visualisation of an algorithm, teamwork with students-experts and addition of context to text of exercises) verified in practice are described there. They can make easier the teacher work in developing students' skills in solving calculus assignments in chemistry, particularly in classes where chemistry is taught at basic level. But the most important issue is to reflect not “how” but “why” a teacher includes calculus problem in her/his own chemistry lessons.
