Abstract

This research aimed to 1) Develop and determine the effectiveness of a supplementary curriculum based on a problem-based learning approach, and 2) Study the effects of implementing the supplementary curriculum. The study employed research and development methodology. The sample consisted of 30 upper secondary school students enrolled in the second semester of the 2023 academic year from two upper secondary schools in Mae Moh District, Lampang Province. The sample was selected through proportional stratified random sampling with 15 students from each school, followed by simple random sampling through lottery drawing from the complete list of upper secondary students in each school. The research instruments included: 1) A supplementary curriculum based on problem-based learning approach, 2) A curriculum implementation manual, and 3) A financial literacy assessment tool. Statistical analyses employed were mean, standard deviation, and t-test. The research findings revealed that: 1) The problem-based learning supplementary curriculum, comprising background and significance, curriculum principles, curriculum objectives, content structure, learning activity arrangements, media and learning resources, and learning assessment and evaluation, demonstrated appropriateness at the highest level (mean = 4.55) with an efficiency rating of 84.73/82.44. The curriculum implementation manual, consisting of curriculum usage instructions, guidelines for instructors, guidelines for learners, curriculum implementation plans, learning units, curriculum content structure, and lesson plans, showed appropriateness at the highest level (mean = 4.51). 2) The results of the supplementary curriculum implementation indicated that students' post-instruction financial literacy scores were significantly higher than pre-instruction scores at the .05 statistical significance level.
