Evaluating the Content Validity of Grade 10 Mathematics Model Examinations in Oromia National Regional State, Ethiopia
This article purports to analyze the content validity of model examinations for grade 10 mathematics. The study looked at the model tests to evaluate if they were indicative of the course content and emphasized on the syllabus’ learning outcomes. A survey design with six years of mathematics model exam, syllabi, and textbooks served as the key data sources was considered in the study. Kendall’s coefficient of concordance and chi-square test of statistical treatment were used to analyze the quantitative data obtained. In addition, the qualitative data were evaluated using narration and description. The study’s statistical findings revealed that there was no relationship between test items and learning outcomes in cognitive domain categories or main textbook content. As a result, the exam items did not correspond to the syllabus’s objectives and content. Furthermore, the qualitative data revealed that the test items were unclear, poorly laid out, and multidimensional, as well as having low content validity.
