The Development of Scientific Problem-solving Ability on Separation Method of Matthayomsuksa 1 Students of the Demonstration School of Nakhon Pathom Rajabhat University Using the Learning Model TGT Combined with Think-Pair-Square-Share Technique

Abstract

The research objectives are to: 1) compare the learning achievements before and after learning by the learning model TGT combined with Think-Pair-Square-Share technique 2) compare the learning achievements after learning by the learning model TGT combined with Think-Pair-Square-Share technique with 70 percent criterion 3) compare the scientific problem-solving abilities after learning by the learning model TGT combined with Think-Pair-Square-Share technique with 70 percent criterion and 4) study the satisfaction of the students towards the learning model TGT combined with Think-Pair-Square-Share technique. This research is a quantitative study of the quasi-experimental type. The sample group is the 45 seventh-grade students at the Demonstration School of Nakhon Pathom Rajabhat University, derived by simple random sampling. The research instruments are: 1) lesson plans 2) an ability test on scientific problem-solving ability 3) an achievement test and 4) a satisfaction form. The statistics used for analyzing data are: t-test for one sample, t-test for dependent samples, mean, percentage and standard deviation. The results revealed that 1) the learning achievement after learning was higher than before 2) the learning achievement after learning was higher than 70 percent criterion with statistical significance at .05 3) the scientific problem-solving ability after learning was higher than 70 percent criterion with statistical significance at .05 and 4) Overall, students expressed a high level of satisfaction with the TGT learning approach combined with the Think-Pair-Square-Share technique.
