Construction of online teaching validity evaluation system based on technology acceptance

Based on the technology acceptance model (TAM), this paper constructs a set of online teaching validity evaluation system, and puts forward the corresponding construction strategy. The research shows that technology acceptance is the key factor affecting the effect of online teaching, and the evaluation system should cover the core indicators such as technology ease of use, technology usefulness, teaching quality and learning effect. The validity of online teaching can be comprehensively and objectively reflected through the comprehensive application of various evaluation methods such as questionnaire survey and learning behavior analysis, combined with scientific data processing technology. This paper also puts forward strategies such as improving teachers' technology application ability, enhancing students' technology acceptance, optimizing teaching resources and platform construction, etc., providing scientific basis and practical guidance for the improvement of online teaching quality.
