Abstract: The effect of English graded teaching reform is still unclear. In order to study the practical application effect of English graded teaching reform, the evaluation method of English graded teaching reform effect in blended learning environment is proposed. Firstly, the characteristics of blended learning environment are analysed, and the time series analysis method is used to collect the data of English graded teaching reform. Secondly, through the optimal cluster analysis criterion, an index system for evaluating the effect of English graded teaching reform is constructed. Finally, the fuzzy comprehensive evaluation method is used to obtain different levels of the effectiveness of English graded teaching reform and complete the evaluation of the effectiveness of English graded teaching reform. The test results show that the highest evaluation accuracy of the proposed evaluation method is 99.03%, and the highest evaluation time is 0.5 hours.

Keywords: mixed learning environment; English level teaching; teaching reform; effect evaluation; fuzzy comprehensive evaluation.
