The Development Mathematics Instruction Based on Constructivist Theory Cooperative with Electronic Media to Promote Problem Solving Skill on Percentages and Ratios for Prathomsuksa 6 Students

Abstract

The purposes of this study were: 1) to develop plans for organization of mathematics Instruction Based on Constructivist Theory Cooperative with Electronic Media on Promote Problem Solving Skill on Percentages and Ratios of Prathomsuksa 6 a require efficiency of 70/70. 2) out the effectiveness index of plans for the organization of mathematics on Percentages and Ratios of Prathomsuksa 6 Instruction Based on Constructivist Theory Cooperative with Electronic Media on Promote Problem Solving Skill. 3)to compare the mathematical achievement of student and mathematical problemn-solving ability who study Instruction Based on Constructivist Theory Cooperative with Electronic Media to Promote Problem Solving Skill on Percentages and Ratios of Prathomsuksa6 Students with 70 percent criteria. The participants in this study were sixteen students who studied in grade 6 at Bankrajai School, Yasothon Province, in the second semester of academic 2022. However, they were selected by using the cluster random sampling technique. The instruments are used in the study were (1) Mathematics learning activities Instruction Based on Constructivist Theory Cooperative with Electronic Media to Promote Problem Solving Skill on Percentages and Ratios for Prathomsuksa 6 Students plan for 18 plans (2) the learning achievement test on percentage and ratio of Prathomsuksa 6 were 20 questions for multiple choices, item-objective congruence index (IOC) of test was 0.80-1.00, the difficult (p) of test was between 0.39-0.78, the discrimination (B) of test was between 0.28-0.80 and the reliability of all the item was 0.88;
(3) the mathetical problem-solving ability test on percentage and ratio of Prathomsuksa 6 were 4 questions for a subjective way of thinking, item-objective congruence index (IOC) of test was 0.80 - 1.00, the difficult (p) of test was between 0.61 - 0.66, the discrimination (B) of test was between 0.61 - 0.68 and the reliability of all the item was 0.76.
The statistics are used for analyzing the data. It consists of percentage, mean, and standard deviation. Moreover, toexamine the hypothesis by using a Hoteling's T²

          The results of the study were as follows: 1) The lesson plans for organization of mathematics learning activities of Instruction Based on Constructivist Theory Cooperative with Electronic Media to Promote Problem Solving Skill on Percentages and Ratios for Prathomsuksa 6 was 77.83/77.50, respectively. 2) The effectiveness index of 0.696, It shows that students’ arithmetic potentials have relatively progressed for 69.66%, 3) Mathematical achievement of students who studied Instruction Based on Constructivist Theory Cooperative with Electronic Media to Promote Problem Solving Skill on percentage and ratio of Prathomsuksa 6 at over 70 percent criteria at .05 and mathematical problem-solving ability of students accounted not over 70 percent criteria at .05 level of significance.
