Developing an observation instrument to measure technological pedagogical knowledge (tpk) of biology teacher in learning process

Abstract

Technological Pedagogical Knowledge (TPK) was a knowledge that must be mastered by the teacher for measuring a suitable technology for supporting the strategic application of teaching. TPK was important to be studied because it was the most influencing aspect for teacher's TPACK. Basically, there was no observation instrument that discovers the TPK of biology teacher. The aim of this research was to develop an observation instrument for measuring TPK of biology teacher in learning process. The method used is design and development research (DDR) by Richey and Klein model. The instrument framework was developed based on educational standard for teacher in Indonesia, and then it was used to develop the items. Instrument will be tested for face validity by evaluation and education experts. Instruments that pass the face validity check were tried out on 11 teachers from six schools in DIY and Central Java region. The result showed that 11 items pass the empirical validity based on point biserial correlation and interater reliability was 0.968 based on intraclass correlation coefficient (ICC)-that means all items in the category were reliable. Thus, the observation instrument is qualified to measure the TPK of biology teacher in learning process.
