Abstract
The purposes of this research were 1) to study the guidelines for case-based learning activities to enhance analytical thinking ability and 2) to study the effects of case-based learning activities on analytical thinking ability in the topic of ratio, proportion, and percentage of students in grade-7, Academic Year 2020. The participants consisted of 12 students in an opportunity expansion school, Nakhon Sawan Province. This research applied classroom action research for 3 cycles which was 10 hours. The research instruments consisted of lesson plans based on case-based learning activities, learning reflection form, worksheets, and analytical thinking ability test. There are 3 subcomponents of analytical thinking ability: critical analysis, correlation analysis, and principles analysis. The data from learning reflection form were analyzed by content analysis and checking for trustworthiness by resource triangulation. While the data from worksheets and analytical thinking ability test were analyzed by rubric scoring in five levels: excellent, good, acceptable, marginal, and poor. Consequently, the case-based learning activities to enhance analytical thinking abilities should emphasize that the teachers should present real-life situations for students which help students to improve critical analysis ability. Moreover, teachers should focus on complete writing in problem solving processes which help students to improve correlation analysis and principles analysis ability. The analytical thinking ability of students proceed with increasing development in principles analysis, correlation analysis, and critical analysis, respectively.
