Abstract:
The objectives of this research were to establish and explore the effectiveness of a curriculum for solving mathematical problems by using the concept of DAPIC problem-solving process for sixth-grade students and study the results of using the enrichment curriculum for the sixth grade students. The samples were 17 sixth-grade students, studying in 2nd semester, Academic Year 2020 at Ban Nong Pla Sawai School were obtained by cluster random sampling. The research instruments were the enrichment curriculum for solving mathematical problems , its manual, and a test of measuring mathematical problem solving skills. The data were statistically analyzed by applying means, standard deviation, and t-test dependent.
The results of the research were as follows:
1. The enrichment curriculum on Mathematical problem-solving skills using the concept of DAPIC problem-solving process for the sixth-grade students included 7 elements: 1) background and significances2) principles 3) aims 4) content structure 5) learning activities 6) learning materials and resources and 7) assessment. The results of the curriculum quality examination by expert panel found that the enrichment curriculum on mathematical problem-solving skills using the concept of DAPIC problem-solving process for sixth grade students obtained a high overall suitability ( = 4.48, S.D. = 0.52). The effectiveness of the enrichment curriculum on mathematical problem-solving skills using the concept of DAPIC problem-solving process for sixth grade students was 0.7322 which indicated that the students learning progress post-studying was higher than pre-studying at a percentage of 73.22.
2. Students who studied with the enrichment curriculum on mathematical problems-solving using the concept of DAPIC problem-solving process had significantly higher Mathematical problem-solving skills of post-study than pre-study at a statistically level of .05
