Development of Science Process Skill and Learning Achievement of Mathayomsuksa 3 Students on The Topic of Genetic Inheritance by Using Stad Technique and Sufficiency Economy Philosophy

Abstract

The purposes of this research were to: 1) develop lesson plan by using STAD technique combined with the philosophy of sufficiency economy on the topic of genetic inheritance to follow the criterion efficiency 80/80, 2) study and compare science process skills of students before and after learning, 3) study and compare learning achievements before and after learning, and 4) study satisfaction of students toward the proposed lesson plans by using STAD technique combined with the philosophy of sufficiency economy. The samples were 41 Mathayomsuksa 3 students at Ban Makkaeng School of the first semester of the academic year 2021, selected by using cluster random sampling. The research instruments included: the lesson plans based on STAD technique combined with the philosophy of sufficiency economy, a science process skills test, a learning achievements test, and a satisfaction questionnaire. The statistics used in the data analysis were percentage, mean, standard deviation, and t-test for dependent sample.

            The results revealed that. 1) The lesson plan by using STAD technique and sufficiency economy philosophy of Mathayomsuksa 3 students on the topic of genetic inheritance had their efficiency of 80.20/80.52, which met the criterion set at 80/80. 2) The students’ science process skills who learned by using STAD technique and sufficiency economy philosophy of Mathayomsuksa 3 students on the topic of genetic inheritance, had the pretest mean score 13.46 points or 44.87 percent and the posttest mean score 24.73 points or 82.43 percent. The students’ science process skills were significantly higher than before at .01 level. 3) The students’ science learning achievement who learned by using STAD technique and sufficiency economy philosophy of Mathayomsuksa 3 students on the topic of genetic inheritance, had the pretest mean score 14.71 points or 48.37 percent and the posttest mean score 23.59 points or 78.61 percent. The students’ science learning achievements were significantly higher than before at .01 level. and 4) The students’ satisfaction toward learning by using STAD technique and sufficiency economy philosophy was at the high level of satisfaction.
