Measurement of TPACK self-efficacy for pre-service science teachers

Abstract

This study aimed to measure the TPACK self-efficacy of prospective science teachers based on Koehler and Mishra’s technological pedagogical content knowledge (TPACK) theoretical framework. The instrument in this study was developed by Kiray, which consists of seven subscales; the total number of items was 55. To test the instrument, 158 students were used as respondents. Research respondents comprised 312 students in a senior year from the Faculty of Math and Science Universitas Negeri Semarang. Confirmatory factor analysis was performed for the construct validity of the scale. The analysis results showed that the number of items from 55 to 49 items and eight subscales. The Cronbach alpha internal reliability coefficient was calculated using SPSS 20.0 as 0.968; reliability composite 0.959, which means the scale developed was feasible to measure TPACK self-efficacy perception of pre-service science teachers. The results obtained indicate that the average TPACK self-efficacy was in the medium category.
