Abstract: In order to solve the problems of inconsistent opinions of domain experts and ignorance of domain experts, preferences in the evaluation of physical language behavior effects of physical education teachers in primary and secondary schools, an evaluation method based on group decision-VIKOR is proposed. An evaluation system was constructed based on the actual use of physical language behaviors of physical education teachers in primary and secondary schools. Based on the group decision-making method, the weights of evaluation indicators that passed the consistency test and were highly authoritative were determined. The physical language behavior effect of physical education teachers in the open class was sorted by VIKOR method. The paper verified the proposed algorithm by analyzing and evaluating the PE open class organized by a central experimental primary school in a district of Taiyuan City from qualitative and quantitative perspectives.
