摘要

This study aims to validate a Pedagogical Content Knowledge (PCK) scale that consists of 56 items. The instrument was distributed to 301 (16 years old) secondary science students. These students were required to respond to a 5 point Likert scale instrument. Using factorial analysis, 16 items were established which was divided into three components of PCK namely i) Knowledge of science pedagogy, ii) knowledge of students and iii) knowledge of concept representational. The final model of PCK was significant (p = 0.000) (RMSEA = 0.075; CFI = 0.910; and TLI = 0.892). This validated survey instrument serves as an evaluation tool for analyzing science teachers PCK that is less laborious and time-consuming.
