The Study of Scientific Computational Skills and Learning Achievement by Using a Set of Learning Activities on Work and Energy for Grade 8 Students at Mathayom Wat Makutkasat School

Abstract

The purposes of this research were 1) ) to test the efficiency of a set of learning activities on the topic of work and energy to be effective following the criteria of 80/80, to compare the grade 8th students’ the scientific computational skills before and after using a set of learning activities on the topic of work and energy, 3) to compare the grade 8th students’ learning achievement before and after using a set of learning activities on the topic of work and energy, and 4) to study the students’ satisfaction toward a set of learning activities. The target group for this research was 30 students in grade 8 at Mathayom Wat Makutkasat School, selected by using a purposive selection. The research tools consisted of a set of learning activities on work and energy topic, the lesson plans, the learning achievement test, scientific computational skill test, and questionnaires. The data were analyzed by the applications of mean (), standard deviation (S.D.), paired-sample t-test, and efficiency (E1 / E2). The results showed that 1) The learning achievement of students was at 94.93 / 80.15 for efficiency rate higher than standard criteria of 80/80. 2) The students had significantly higher scientific computational skills after learning through a set of learning activities at the significant of .05. 3) The students had significantly higher learning achievement after learning through a set of learning activities at the significant of .05. 4) The students were satisfied toward using a set of learning activities on the topic of work and energy with the overall average (  = 4.50, S.D. = 0.55), which were at a high level.
