Exploring the Development, Dilemmas and Countermeasures of College English Teaching by Combining the Hierarchical Analysis Approach

College English teaching has formed a long-term historical persistent problem in the process of higher education expansion, and it is urgent to explore its development dilemma and corresponding countermeasures. This study uses hierarchical analysis to analyze the connection between relevant factors in English teaching activities, constructs a judgment matrix for teaching evaluation, establishes the index ordering through a consistency test, and applies intuitive fuzzy logic to establish the index weights. At the same time, a genetic algorithm was applied to the weight optimization process to iterate the better matrix indicator weights. After verifying the optimization effect through experiments, the comprehensive assessment method was applied to specific teaching cases and analyzed. The comprehensive evaluation results of students, teachers, and experts were obtained respectively, the latter being [0.3459 0.2961 0.1848 0.1086 0.0636]. The final evaluation result of the university English teaching case is [0.3358 0.2790 0.1874 0.1272 0.0695], which corresponds to the grade of “general”. Through the evaluation of university English teaching, the difficulties of current English teaching are fed back, which lays the foundation for the countermeasures to be put forward.
