Developing a Mathematics Homework Evaluation Scale (MHES) for Secondary School Mathematics Teachers

This study aims to develop a valid and reliable scale that shows the secondary school mathematics teachers' evaluations of mathematics homework. A literature review was conducted, and a pool of 41 articles have been prepared for this purpose. Five expert academicians in the field of mathematics education were consulted for the content, construct, and appearance validity of the prepared items. According to the opinions of the field experts, the number of items was reduced from 41 to 38 and applied to 492 mathematics teachers in total. The answers of 20 mathematics teachers were removed from the scope of this study since the answers were either incomplete or coded incorrectly. Therefore, scale forms collected from 472 mathematics teachers were included in this study. This form data was split, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were done. The construct validity was analyzed via EFA. The scale is a five-factor scale of the five-point Likert scale, which explains the 64.643% of the total variance with 21 items according to EFA results. The reliability of the scale was tested with Cronbach's Alpha coefficient, and the coefficient was calculated as 0.737. The subscales of the scale are titled "Parent Relationship", "Motivation", "Control and Evaluation", "Time" and "Source Use" respectively. CFA was carried out for the scale, and it was concluded that the fit indices are either acceptable or perfect. As a result, a reliable and valid "Teacher Approaches for Mathematics Homework Scale" has been added to the literature.
