THE RELIABILITY OF AN INSTRUMENT TO MEASURE TEACHER KNOWLEDGE FROM THE PERSPECTIVE OF LEARNERS IN THE CONTEXT OF PIBID

Summary/Abstract: This research sought to analyze the reliability of an instrument to measure teacher knowledge of a group of pre-service chemistry teachers participating in the Institutional Program for Scholarships for Beginner Teachers in Brazil (PIBID).. Thus, it was analyzed the evaluation of a group of students about the Pedagogical Content Knowledge (PCK) of five pre-service chemistry teachers from the program. Accordingly, an instrument containing 28 statements and an open question was applied to a group of 70 students from a public school to whom the pre-service teachers had applied their didactic proposals. The purpose of the instrument was to measure the perception of the students' about the components of the teacher knowledge (Subject Matter Knowledge - SMK, Instructional Representation and Strategies - IRS, Instructional Objective and Context - IOC and Knowledge of Students’ Understanding - KSU) of the pre-service teachers. The results of the analysis revealed that the instrument about teacher’s knowledge has a high reliability based on the alpha Cronbach values. The results of the alpha coefficient for the pre-service teachers were all above 0.9 suggesting that the instrument is reliable and has consistent measurements. Regarding to the exploratory analysis, the main scale in the PCK evaluation of the undergraduates was four which means that the students consider that the aspects related to the SMK, IRS, IOC and KSU are frequently present in the classes of the future teachers.
