The Research of the Knowledge Structure Optimization for the Virtual Reality Teaching Based on Genetic Algorithm

According to the teaching and learning with virtual reality system, it is a problem that to have extensive and professional knowledge is needed. This paper has proposed a new method of knowledge structure optimization based on the genetic algorithm. Through analyzing the relationship between the correct rate of student answer, correct score rate and total score rate, the mathematical model of student knowledge structure has been constructed. The selection operator has dynamically been adjusted by genetic algorithm, which is used to optimize the structure of knowledge. Through the experiment it has been proved that the method is the feasibility and effectiveness.
