The Integration of CPA Process and Mathigon Program to Enhance Mathematical Problem-solving competency on Ratio, Proportion and Percentage among Seventh-grade Students

Abstract

The skills and processes of mathematical problem-solving are important components of 21^st century skills that learners should be developed. Therefore, researchers aim to find ways to develop learners to have such skills. The research aimed to 1) study the integration of the CPA process and the Mathigon program and 2) study the results of the integration of the CPA process and the Mathigon program to promote the ability to solve mathematical problems on ratios, proportions and percentages of Mathayom 1 students. The target group was 20 Mathayom 1 students of a secondary school in Sukhothai Province, who is studying in the second semester of the 2023 academic year. The research instruments consisted of three learning management plans, a learning management reflection form, activity sheets, and a mathematics problem-solving ability test. Data was analyzed using content analysis and triangulation of data sources, and analysis using separate scoring criteria. The research results found that 1) The condition of the integration between CPA process and the Mathigon program started with using tangible media and changed to images to help illustrate concepts. It then developed into the presentation of abstract concepts including continuous assessment, creation of connections, and the use of technology. 2) The results of integrating CPA process and the Matrix program found that learners had increased ability to solve mathematical problems and were at a good level. The ability to understand problems was at the highest level, followed by problem-solving operations, problemsolving planning, and answer checking, respectively.
