Development of Problem-Solving Skills and Learning Achievement in the Legal Issues of Everyday Life through Phenomenon-Based Learning with R-C-A Questioning Technique for Grade 10 Students

Abstract

The purpose of this research was to develop problem-solving abilities and learning achievement in the topic of "Law in Daily Life" for Mathayomsuksa 4/3 students at Khon Kaen University Demonstration School (Secondary Division, Faculty of Education) in the first semester of the 2024 academic year using the Phenomenon-Based Learning model combined with R-C-A questioning technique. The criterion was set that no less than 70 percent of students must achieve scores of 70 percent or higher. The sample group consisted of 36 students selected by purposive sampling. The research was conducted using an Action Research methodology with the following research instruments: 1) six lesson plans using the Phenomenon-Based Learning model combined with R-C-A questioning technique, 2) problem-solving ability tests, and 3) learning achievement tests. Quantitative data were analyzed using basic statistics, including mean and percentage, while qualitative data were analyzed through content analysis and summarized in narrative form. The research results revealed that 73.04 percent of students demonstrated problem-solving abilities meeting the specified criteria, and 76.30 percent achieved learning outcomes meeting the specified criteria. This reflects that the Phenomenon-Based Learning approach combined with R-C-A questioning techniques encourages students to develop participatory thinking processes as global citizens through problem analysis, knowledge inquiry, and presentation of diverse problem-solving approaches, while also resulting in higher learning achievement.
