Abstract
The aims of this study is to develop an observation instrument and test the validity and reliability used to measure the performance of biology teachers to apply TPACK in the learning process. This research is included in the DDR. The steps to develop TPACK observation instruments are, (1) analysis of products to be developed; (2) initial product development; (3) product validation; (4) field trials; and (5) product revisions. TPACK observation instrument was trialed on 11 biology teachers in two provinces, Yogyakarta and Central Java in August 2018, involving 4 rater. Face validity and empirical validity were carried out. Instrument face validity involves 2 expert judgements and empirical validity is determined by looking for Biserial Correlation value. Intraclass correlation coefficient (ICC) is used to test reliability. Empirical validity based on the value of Biserial Correlation shows that all items are valid with R count> 0.602. The reliability value of the TPACK instrument disclosed by the ICC is 1,000, which means that the instrument has a high reliability level. In addition, the development of both reliable and valid scale related to the technological pedagogical content knowledge of biology teachers’ would be promote further studies.
