The Development of Mathematics Learning Activities by Using The STAR Strategy Steps with using Electronic Media to Enhance Mathematics Problem Solving Ability in Problem of Percentage of Prathomsuksa 5 Students

Abstract

The purposes of this study were 1) to development of Mathematics Learning Activities by Using The STAR Strategy Steps with using Electronic Media to Enhance Mathematics Problem Solving Ability in Problem of Percentage of Prathomsuksa 5 Students efficiency of 75/75; 2) to study an effectiveness index of plans; 3) to compare the mathematical achievement of students with 75 percent criteria; 4) to compare the mathematical problem solving with 75 percent criteria; 5) to explore the satisfaction of students on their learning activities. The participants in this study were thirteen students who studied in grade 5 at Ban Pansri School, Surin Province. However, they were selected by using the cluster random sampling technique. The instruments are used in the study were: mathematics learning activities using The STAR Strategy Steps with using Electronic Media plan for 18 plans; the learning achievement test were 20 questions for multiple choices; item-objective congruence index of test was between 0.80-1.00,        the difficult of test was between 0.25-0.80, the discrimination of test was between 0.21-0.92 and the reliability of all the item was 0.51 the mathematical creativity ability test were 5 questions for a subjective way of thinking, item-objective congruence index was 1.00, the difficult of test was between 0.30-0.42, the discrimination of test was between 0.28-0.50 and the reliability of all the item was 0.87; and the satisfaction of students’ tests on their learning activities were 5 levels, 10 items, they were rating scales which had the content validity was 1.00. The statistics are used for analyzing the data.          It consists of percentage, mean, and standard deviation. Moreover, to examine the hypothesis by using a t-test for One Sample.

       The results of the study were as follows: the lesson plans for organization of mathematics learning activities using The STAR Strategy Steps with using Electronic Media and content knowledge consists of 4 steps had an efficiency of was 93.31/85.00. The effectiveness index of plans was 0.8098, or 80.98 percent, respectively. Mathematical achievement accounted for 85 percent at over 75 percent criteria at 0.05 level of significance.Mathematical creativity of students who studied The STAR Strategy Steps with using Electronic Media to Enhance Mathematics Problem Solving Ability in Problem of Percentage of Prathomsuksa 5 Students  accounted for 84.62 percent at over 75 percent criteria at 0.05 level of significance. Moreover, the satisfaction of the students with learning was satisfied total at a high level ( =4.70 and S.D.=0.46)
