Table 1_Quality education from the perspective of landsenses ecology: research on performance evaluation of L2 teaching materials based on Importance-Performance Analysis.pdf

Based on a questionnaire survey of L2 learners, this study aims to construct a dual mechanism: firstly, Importance-Performance Analysis is applied to identify the dimensions that need to be prioritized for improvement in the target teaching materials, and then mediation analysis is conducted to reveal the psychological pathways through which teaching materials influence learning outcomes.

The results show that the perceived performance of landsense indicators is significantly lower than their importance, revealing a systematic performance gap that traditional unidimensional evaluation fails to capture. Furthermore, teaching material performance is positively correlated with foreign language enjoyment, and foreign language enjoyment is positively correlated with learning engagement. Learning engagement is further positively correlated with learning efficiency.
