A MODEL TEACHING METHOD BASED ON COMPUTATIONAL THINKING IN COLLEGE PHYSICS TEACHING—TAKING THE MOLECULAR SPEED DISTRIBUTION LAW OF IDEAL GAS AS AN EXAMPLE

The goal of this paper is to explore a model teaching method of introducing computational thinking into college physics teaching. Taking the teaching of ideal gas molecular speed distribution law as an example: assuming that the velocities of some ideal gas molecules are obtained by random sampling from a thermodynamic equilibrium system, this paper discusses how to analyze and obtain the distribution of molecular speed in the system by numerical calculation, and introduces the definition of speed distribution function. By comparing with Maxwell's speed distribution law, the temperature of the system is fitted with Matlab calculation tool, which is highly consistent with that obtained by the average translational kinetic energy of the ideal gas. It is concluded that the cultivation and training of computational thinking in college physics teaching is of great significance. Similar thinking training can better improve students' ability to deal with physical problems with computers. Some teaching suggestions of the author are put forward.
