Fuzzy cluster correlation mapping for online evaluation of teaching efficacy towards IoT study

This research investigates the TPACK structure and its technology integration self-efficacy situation of 150 foreign language teachers, adopts cluster classification mapping fuzzy correlation clustering structure equation model to conduct route analysis on the relationship between them. The research shows that the foreign language teachers have insufficient preparation on TPACK and have low level of technology knowledge; their technology integration self-efficacy and various dimension levels are moderate, but they have insufficient confidence in integrating teaching through technology to enhance learning quality; The TPACK presents positive relation with the technology integration self-efficacy, and TPACK had positive prediction and significant influence on technology integration self-efficacy, namely the knowledge structure of teachers (TPACK) is the motivation to their confidence in technology and teaching integration.
