Construct validity pedagogy competency instrument of teaching and learning practice program (TLPP) students: Unidimensional confirmatory factor analysis

Pedagogy competency instrument is a tool to measure the achievement of teacher candidate students' ability of the teaching and learning practice program (TLPP). Various studies state the importance of this competency in supporting students in learning to use knowledge and action when teaching practices in the classroom. But there is a gap in the assessment because the instruments have not been able to measure this competency. Therefore, it is necessary to prove the validity of the construct to the items in the instrument. By looking to the concept, there are 4 dimensions which are used in composing the instrument such as effective classroom management, effective teaching practices, effective assessment, and technical skill. This study aimed to test that construct instrument validity. This study model used in design and development model. The data obtained from the experiment of teaching trial students were 177 persons observed by 67 teachers. Technic of data analysis to prove construct validity was first order confirmatory factor analysis (CFA) with the help of LISREL 8.70 software. The results showed that from all items which were 43, there was 1 item stated as invalid and 42 items were valid or unidimensional with T-Value on the loading factor value > 1.96. This finding successfully proves that the unidimensional data parameter can measure the construct and give significant effects. It is expected that the finding of this research can complete the constructive knowledge of the items of pedagogical competency assessment of TLPP students and contribute to improving the quality of teaching into a good teacher in the present and future.
