DEVELOPMENT OF LEARNING ACTIVITIES BY USING PROBLEM-BASED LEARNING APPROACH COMBINED WITH HIGHER-ORDER QUESTIONS TO PROMOTE THE PROBLEM-SOLVING ABILITY OF GRADE 10 STUDENTS

Abstract

       The objectives of this research were 1) to develop learning activities by using problem-based learning approach combined with higher-order questions. To meet the standard criterion set at 75/75, and 2) to compare problem-solving abilities before and after learning activities by using  problem-based learning approach combined with higher-order questions. The sample used in this research consisted of 42 grade ten students in the second semester of the academic year 2023, Phonthongpattanawittaya School obtained by the cluster random sampling technique. The research instruments were             1) problem-based learning approach combined with high-order questions lesson plans, and 2) Problem solving ability tests. Using a quasi-experimental research format with a single sample group (One-Group Pretest-Posttest Design). The statistics used for data analysis were mean, percentage, standard deviation, and t-test.

           The results showed that 1) learning activities by using problem-based learning approach combined with higher-order questions to promote problem-solving abilities of grade ten students was 82.13/79.08, which means it was higher than the 75/75 set criteria, and 2) The post-test average score of grade ten students after using problem-based learning approach combined with higher-order questions was higher than the pre-test average score at a significant level of .05.
