Designing a reasonable combined teaching scheme is not only the need to achieve teaching optimization, but also a reasonable choice to improve the overall level of teaching efficiency. The existing researches lack an evaluation system to judge the rationality of their designs. Therefore, this paper takes music teaching as an example to carry out the research on the construction of combinatorial teaching evaluation system based on STATA analysis. Firstly, the implementation process of the combined teaching strategy is provided here, and the construction of the combined teaching evaluation system is carried out from seven aspects, namely teaching in fun, emotional experience, student engagement, elicitation and induction, teaching according to students’ aptitude, creative development and vividness and intuitiveness. The entropy weight method is adopted to assign the weight of the combined teaching evaluation index of music major courses. Based on stata15.1 software tool, regression analysis is carried out on the main factors that affect the effect of combined teaching, and the relevant regression analysis model is constructed to realize the effect prediction of short-term combined teaching scheme in the case of small samples. The experimental results verify the effectiveness of the evaluation system and analysis model.
