Research on Teaching Quality Evaluation of Engineering Cost Major Courses in Universities Based on GRA Algorithm

Teaching quality assessment is an important part of curriculum education and teaching management in universities. The assessment results can provide support for optimizing and innovating curriculum teaching plans, and help improve the quality of teaching work in universities. This article takes the engineering cost major courses in universities as an example to construct a teaching quality evaluation index system, and based on the GRA algorithm, establishes a teaching quality evaluation model for engineering cost major courses in universities. Through data verification, it is found that the evaluation model established in this article has a quality level evaluation accuracy of 93.3% compared to the comprehensive evaluation results of school expert groups and teacher mutual evaluation of teaching quality, while the average error of scores is 2.96%, respectively. This indicates that the model constructed in this article is usable. At the same time, through comparison and verification with commonly used linear models and fuzzy comprehensive evaluation models, it is found that the evaluation performance of the model constructed in this article is better and suitable for teaching quality evaluation of engineering cost major courses in universities.
