Problem-Based Learning Management with Electronic Media to Develop Academic Achievement and Promote the Ability to Relate Mathematically on Percentages and Ratios of Prathomsuksa 6 Students

Abstract

The purposes of this study were: 1) to develop plans for organization of mathematics Instruction Based on Problem-Based Learning Management with Electronic Media on Percentages and Ratios of Prathomsuksa 6 a require efficiency of 70/70. 2) to study the effectiveness index of plans for the organization of mathematics on Percentages and Ratios of Prathomsuksa 6 Instruction Based on Problem-Based Learning Management with Electronic Media. 3)to compare the mathematical achievement of student and mathematical associative abilities who study Instruction Based on Problem-Based Learning Management with Electronic Media on Percentages and Ratios of Prathomsuksa6 Students with 70 percent criteria. The population in Prathomsuksa 6 at Rattanaburi 4 School network group. The participants in this study were fifteen students who studied in Prathomsuksa 6 at Banchongyangchum School, Susin Province, 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 Problem-Based Learning Management with Electronic Media 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 0.38-0.75, the discrimination (B) of test was between 0.25-0.38 and the reliability of all the item was 0.70 (3) the mathematical associative abilities 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 0.57-0.63, the discrimination (B) of test was between 0.44-0.49 and the reliability of all the item was 0.65. The statistics are used for analyzing the data. It consists of percentage, mean, and standard deviation. Moreover, to examine 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 Problem-Based Learning Management with Electronic Media on Percentages and Ratios for Prathomsuksa 6 was 76.33/74.33, respectively. 2) The effectiveness index of 0.6786, It shows that students’ arithmetic potentials have relatively progressed for 67.86%, 3) Mathematical achievement of students who studied Instruction Based on Problem-Based Learning Management  with  Electronic Media on percentage and ratio of Prathomsuksa 6 at over 70 percent criteria at .01 and mathematical associative abilities of students accounted over 70 percent criteria at .01 level of significance.
