ความสามารถในการแก้ปัญหาทางคณิตศาสตร์ของนักเรียนชั้นประถมศึกษาปีที่ 3 ที่เรียนคณิตศาสตร์แนวใหม่ / บุหงา วัฒนะ = Mathematical problem solving abilities of prathom suksa 3 students trained in modern mathematics / Bu-nga Watana
The purpose of this study is to compare the mathematical problem solving abilities of Prathom Suksa 3 students who are trained in modern mathematics and those who are not. The result of this study will be used for the improvement of modern mathematics program and traditional mathematics program. One hundred and thirty one of Prathom Suksa 3 students trained in modern mathematics at Payatai School, Piboolupatham School and Wat Vetawanthanmavas School were used as the experi- mental group. One hundred and thirty eight of Prathom Suksa 3 students not trained in modern mathematics at Wat Mahabuts School and Wat Chanasongkram were used as the control group. The random sampling in experimental group and control group were the same as in Miss Duangduen Onnaum's study in Academic Year 1970. Her thesis title was "A Comparative Study of the Mathematical Problem Solving Abilities of Second Graders with Training in Modern Mathematics and those without." She constructed the readiness and number concept test to measure the level of mathematical ability of students and to be used as the criterion for a comparison. The problem solving test was used for this study. The reliability coefficient of the test was 0.85. This was designed to measure the mathematical problem solving ability of students. All the problem solving test done by the students had been assessed in order to compare the mathematical problem solving abilities between two groups by using the significance of dif- ferences between means of each group which was found by computing the critical ratio at the level of significance .05. The result of this study showed that there were no signi- ficant differences in problem solving abilities, finding the process, analysing the problem and finding the solution between students who recerived modern mathematics teaching and traditional mathematics teaching, as well as between boys and girls. When each matched group had a qualified and experience teacher teaching them, the results of the study proved that the students trained in modern mathematics acquired CKOR VE more problem more problem solving abilities than the students not trained that way. The students trained in modern mathematics acquired more power in analysing the problems than the student not trained in modern mathematics but in finding the process and solution there was no significant difference between the two groups. The recommendation is that the students trained and not trained in modern mathematics should have the opportunity to solve mathematical problems by themselves. Teacher's role is to quide, correct, and foster the student's problem solving ability.
