There were three Purposes of the study: 1) to development and identify educational quality of science activity packages learning on “The Basic Household Wastewater Management Methods” for Mathayomsuksa 1. (Grade 7) students to attain the efficiency index of 80/80.
2) to study learning outcomes; knowledge and science process skills of MS 1. Students by science activity packages learning. 3) to study attitude toward water resources of MS. 1. Students by science activity packages learning. and 4) to study the MS. 1 students’ toward satisfaction in the science activity packages learning. The study was accomplished through two stages of operation; 1) development and quality evaluation of science activity packages learning by the experts and conducting a teaching experimentation with a group of three students nine students and thirty students successively. 2) performing experimental teaching by employing the science activity packages learning with the sampling coming up with a group in one class (from 4 class of 40 MS.1 in the first semester of 2025 academic year of Sriboonyanon school ) for 16 periods (50 minutes a period)for the experimental teaching.
The results were as follows:
1.The science activity packages learning were at higher educational quality and efficiency index 82.65/83.84.
2. Learning outcomes of students exposed to instruction utilizing the developed science activity packages learning were found to be positive: 1) students’ post-test scores on knowledge were significantly higher than their pre-test scores, 2) The students’ posttest scores on science process skills were significantly higher than their pre-test scores (p<.05). 3. Students’ post-test scores on attitude toward water resources designated as "good” level". 4. Students’ toward satisfaction in science activity packages learning were of a “highly” level.
