oa Mosenodi - Content Evaluation of Physics Textbooks used in Botswana Secondary Schools



The paper evaluates the content of four physics textbooks used in Botswana senior secondary schools. Emereole's extension of Nworgu's Quantitative Approach for the Content Evaluation of Science Textbooks (QACEST), was used to evaluate the subject content. The Flesch Read Ease formula and the Cloze Test were used to evaluate the readability and comprehensibility of the books for the learners. A 10-point Likert-type questionnaire was used to estimate physics teachers' views on the books' ability to provide instructional support in various areas.
