System for Testing Physics Knowledge

Abstract

The model of the physics knowledge testing system is described. The paper presents an approach to building a system for testing procedural physics knowledge, i.e. knowledge of basic physics laws and the ability to use them. This approach consists of constructing mathematical models for each academic module in a physics course. The main constructive objects are test templates, which are mathematical models of test tasks, based on physics models of systems, processes and phenomena. A template of a class of physical tests for testing knowledge of the laws of physics and the abilities of transformations of a physical system is represented by a set of elements of various formats. This set consists of geometric drawings, diagrams, graphs of functional dependencies, a system of formulas for converting physical quantities, patterns of scenarios for changing states of a physical system, and a response pattern. Each such template can be used both in generating similarity algorithms for specific multiple tests, and in algorithms for automatically checking the correctness of answers. The proposed method allows describing a relatively simple class of specific tests. An important characteristic of the system is the ability to automatically check both the final answer and the parameters of the intermediate states of the physical system. The implementation of a procedural physics knowledge testing system can be performed by creating software interactive multimedia objects using the methods of computer mathematics and algebraic programming technology. The model for the testing knowledge system in physics was implemented in the software module for the distance learning system. A model for testing the knowledge system in physics was implemented in the software module for the distance learning system.
