Designing, construction and validating a tool to measure the effectiveness of the teaching process of student teachers in the internship course for intern professors

The purpose of this research was to develop and validate a tool to measure the effectiveness of the teaching process of student teachers in the 4th internship course.Content analysis was used to design the tool.First, the existing rubrics and textbooks of internship 4 in Farhangian University were analyzed and the semantic codes that included the concept of teaching effectiveness in its various fields(design, implementation, evaluation) were selected.66 semantic codes were extracted and after obtaining experts' opinions and making corrections, 66 items were reduced to 56 items.In the pilot implementation, the intended tool was implemented among a sample of 42 student teachers and the questions that needed to be revised were modified and finally, in the next step, 384 student teachers completed the questionnaire.The content validity of the research was confirmed by ten expert professors and its construct validity was investigated by factor analysis. Based on exploratory factor analysis with Varimax rotation, 56 items were placed in 4 factors, and these four factors in total explain 61.574% of the variance of the total scores. the results of the first and second confirmatory factor analysis and Cronbach's alpha coefficients supported the 4-factor structure of 56 items and confirmed its validity and reliability.
