بناء أداة لتقويم محتوى كتاب الفيزياء للمرحلة الثانوية بمملكة البحرين وفق المعايير الوطنية للتربية العلمية

Abstract

Abstract : The purpose of this study was to develop a tool to assess the content of the physics textbook for secondary schools in the Kingdom of Bahrain based on the National Science Education Standards (NSES) and to investigate the relationship between teachers' ratings of the physics textbook content and some variables of interest. The final version of the measure included 30 items that conform to validity standards and cover four domains related to the content of the physics textbook: Scientific concepts and processes; Scientific inquiry skills; Physics for the individual and society; and Modern technology in physics. After that, the developed tool was administered to 57 randomly selected physics teachers in secondary schools in Bahrain, and its psychometric properties were adequately investigated. As a result, high validity and reliability indices were obtained, where the reliability value for the whole measure was .93, indicating the applicability of the developed tool to the measurement of physics content in secondary schools Moreover, the study revealed statistically significant differences in the mean teachers' rating of the content of the physics book that can be attributed to gender, in favor of males. No statistically significant differences, however, were found in the mean teachers' rating of the content of the targeted physics book that can be attributed to the level of educational and scientific qualifications, teachers' professional experience, and teachers' training in the field of assessment. Based on the results, using the developed tool to pinpoint the strengths and weaknesses of the content of the physics book assigned for secondary school and to enhance it in view of scientific developments is recommended. The findings also serve as a profound basis for designing valid tools to measure the content of other scientific subjects in secondary school based on the National Science Education Standards.
