Abstract

This article aims to: 1) Develop a science learning kits on the topic "Substances Around Us" for Grade 6 students based on the 80/80 efficiency criterion; 2) Compare the learning achievement before and after learning between the groups that used and did not use the learning kits; 3) Compare the learning achievement between the groups that used and did not use the learning kits; and 4) Examine students satisfaction with the learning kits. The population consisted of Grade 6 students from the BannangSta Network Center, while the sample group included Grade 6 students from BannangSta Intharachat Mittrapap 200 Memorial School, selected through multi-stage sampling. Research instruments included the learning kits, which was validated for accuracy and appropriateness at the highest level; lesson plans incorporating the learning kits, which were also validated at the highest level; lesson plans without the learning kits, validated at the highest level; an achievement test with an item-objective congruence (IOC) range of 0.67 - 1.00 and a reliability coefficient of 0.85; and a satisfaction questionnaire with an IOC range of 0.67 - 1.00. Data were analyzed using mean, standard deviation, dependent t-test, and independent t-test. The findings revealed that: 1) The learning kits had an efficiency of 80.82/81.03; 2) Students in both groups those using and not using the learning kits showed significantly higher post-test scores than pre-test scores at the .05 level; 3) Students who used the learning kits achieved significantly higher learning outcomes than those who did not at the .05 level; and 4) Students satisfaction with the learning kits was at a high level.
