High School Students’ Perception to Teachers’ Knowledge
Abstract: We developed an instrument to assess high school students’ perceptions of teachers’ knowledge (SPTK). Confirmatory factor analysis were conducted to test the validity of the instrument and RMSEA and SRMR are calculated simultaneously (RMSEA=0.064, SRMR= 0.052). The four subscale reliabilities of SMK, TK, KSU, and TPACK are calculated as 0.91, 0.88., 0.90, and 0.91, and the total scale reliability is 0.96. Participants included 287 high school students of the 4 student English teachers who have been tracked through their practicum and internship with previous workshop training of CALL through TPACK framework. We then ran a stepwise regression where TPACK as the dependent variable was predicted by the remaining constructs of SPPETK. The final selected model (M3) was statistically significant (F = 172.63, p < .001) with an adjusted R² of 0.64 (see Table 2). Several findings are noted from the process of stepwise variable selection: first, TK alone explained 59% of the variance in TPACK sc
