An instrument for measuring self-efficacy beliefs of secondary school physics teachers

This work presents the procedures and results of the validation process of a data collecting instrument to survey the self-efficacy beliefs of Secondary School Physics Teacher's. This instrument consists of a Likert scale questionnaire applied to a sample made up of 136 Physics Teacher's from Brazil. The collected data were submitted to the application of some statistical tests, as item-total correlation, reliability and factor analysis. We conclude by pointing out the congruity of our results with those of other investigations, we presented the validated version of the instrument. Among the main implications of this study we hope to contribute to the research on the self-efficacy beliefs of Physics Teachers so that we can better understand which elements influence the teacher-student relationship regarding motivational beliefs in the classroom
