Study Problem Solving Mathematical Skill According Concept Mayer of Matayomsuksa 3 Students

Abstract

This research aims to study problem solving mathematical skill According concept Mayer of Matayomsuksa 3 Students, Thawat Buri Thawat Buri Roi - ed in the second semester of the academic year 2556, the target group was 28 students. The researcher gave the study problem solving mathematical skill according concept Mayer test. And interview data analysis The case study method was used by 4 students (the researcher studied mathematics problem solving skills based on the 4-Meyer concept). Bring interview interviews about study problem solving mathematical skill according concept Mayer to analyze the problem solving skills of each student. The tools used in the research were the problem solving mathematical skill according concept Mayer test 3 items. The results showed that problem solving mathematical according concept Mayer of Mathayomsuksa 3. Students use problem solving mathematical skills. Behavioral level from the test Students have the highest level of behavior in problem translation skills, followed by the problem integration skills , Solution execution skills , And the level of behavior that students use least in Solution planning and monitoring skill , And find the frequency and percentage. In the whole of the solution to all three problems, students have solved math problems. Each of the four skills are ranked in descending order Problem translation skill , Problem integration skill , Solution execution skill and Solution planning and monitoring skill. The results students of the solution analysis of the problem solving mathematical skill according concept Mayer of Mathayomsuksa 3. The results of the interview Students with weak skills The students have different skills to find out that the students are weak Problem translation skill Can explain what the proposition wants to know. And what the problem is told. But students also explained and did not complete the details. Problem integration skill students with weak skills build up a mental representation of the problem to only partially relate the data relationships. Can’t fully explain what knowledge to solve the problem. Solution planning and monitoring skill students with weak skills can translate into inequalities. But do not explain the problem solving. And do not set variables to find the answer, for example, do not set variables to solve the problem of inequality. And final skills Solution execution skill students with weak skills use basic knowledge to solve math problems. But wrong, students write numbers to multiply wrong inequalities. This makes it a mistake to solve inequalities.
