Abstract

This research aimed to 1) develop problem-based learning activities combined with graphic organizer techniques to enhance problem-solving ability on the topic of pricing and wages for Matthayomsuksa 4 students to achieve an efficiency of 80/80, 2) compare the problem-solving ability before and after learning, 3) compare the learning achievement before and after learning on the topic of pricing and wages, and 4) examine students' satisfaction toward learning activities. The sample consisted of 24 Matthayomsuksa 4/1 students at Phanamtip Wittaya School, obtained through cluster random sampling. The instruments comprised lesson plans, a problem-solving ability assessment, a learning achievement test, and a satisfaction questionnaire. The statistics used for data analysis included percentage, mean, standard deviation, and hypothesis testing using the Dependent Samples t-test.

 The research findings revealed that:  1) the problem-based learning activities combined with graphic organizer techniques had an efficiency of 82.02/80.33, which was higher than the specified criteria.   2) the problem-solving ability of students was significantly higher than before learning at the .05 level.  3) the learning achievement of students on the topic of pricing and wages after learning was significantly higher than before learning at the .05 level. 4) the students' satisfaction toward learning activities was overall at a high level.
