Open Approach Learning Activity Affecting Science Argumentation Skills of Mathayomsuksa 5 Students

Abstract

The purposes of this research were 1) to develop an open approach learning activity that affects science argumentation skills with a required efficiency of 70/70 2) to develop science argumentation skills of Mathayomsuksa 5 students through the open approach to pass the good level 3) to compare learning achievement on sound wave of Mathayomsuksa 5 students through open approach learning activity with 70 percent criterion. The sample in this study was a group of 40 students of Mathayomsuksa 5 in the 2^nd semester of the 2021 academic year at Wapipathum school. The research instruments included 1) the lesson plans on sound wave 2) the argumentation ability test 3) the achievement test. Statistics used in this study consist of percentage, mean, standard deviation, and one sample t-test.

            The results were as follows: 1) The open approach learning activity that affects science argumentation skills had the efficiency (E₁/E₂) of 79.63/78.74, higher than the predetermined criterion of 70/70. 2) 36 students which were 90.00 percent of students who had learned science argumentation skills through the open approach learning activity passed at the good level. 3) Students who had learned through the open approach learning activity had learning achievement of more than 70 percent criterion with the statistical significance of .01 level.
