Development of Science Process Skills of Prathomsuksa 6 Using Experimental Activities Package on Separation of Substances

Abstract

The four objectives of this study were: 1) to develop an experimental activities package on the separation of substances of Prathomsuksa 6 on the efficiency of the process and overall result at the established criteria of 70/70; 2) to compare scientific process skills before and after learning; 3) to compare student’s achievement on similarity before and after learning; and 4) to investigate the students’ satisfaction on experimental activities package. The research sample was Prathomsuksa 6 students consisting of 138 people in the 1^st semester of the academic year 2022 at an educational service area in Kamphaengphet province. They were selected by Simple random sampling. The research tools consisted of an experimental activities package on the separation of substances; the lesson plans; an achievement test; a test for measuring scientific process skills; and a questionnaire on students’ satisfaction. The collected data were analyzed by using percentage, mean, standard deviation, and t-test (dependent sample). The research results were as follows:

1. The experimental activities package on the separation of substances had efficiency values of 79.75/77.75, which meets the 70/70 criteria.


2. The students’ science process skills after learning through the experimental activities package were significantly higher than before learning at the level of .05.


3. The learning achievement after learning through the experimental activities package was significantly higher than that before learning at the level of .05.

       4. The students’ overall satisfaction with the experimental activities package on the separation of substances was at a high level.
