Master’s theses “Application Physics Practical Tasks and Reasoning Schemes in Teaching Mechanic Concepts“ consists of an introduction, 3 sections, conclusions, references to literature and 3 annexes. 8 tables and 18 pictures are presented in the work. The work comprises 72 pages (83 with annexes). Application physics practical task and reasoning schemes, teaching mechanic concept is examined in the theses.
