Abstract:
The purpose of this research was to develop CAI in chemical equilibrium lessons for
matthayomsuksa 6 students in order to have efficiency which reaches the standard 80/80 and to compare
students’ learning achievement before learning by CAI in chemical equilibrium lessons and after learning
at Srinakharinwirot prasarnmit demonstration school.
The sample consisted of 39 matthayomsuksa 6 students at Srinakharinwirot Prasarnmit
Demonstration school (secondary) in the academic year 2019. One Group Pretest-Posttest was employed
in this study. The data was analysed by t-test for dependent sample.
The results of this study indicated that:
1. CAI in chemical equilibrium lessons for matthayomsuksa 6 has efficiency at 82.57/88.10 which is
in accordance with the standard 80/80.
2. Students’ learning achievement after learning by CAI in chemical equilibrium lessons was
higher than students’ learning achievement before learning by CAI in chemical equilibrium lessons with
significant difference at .01 level.
3. Students’ attitude towards the subject of science after learning by CAI in chemical equilibrium
lessons was higher than the one before learning by CAI in Chemical Equilibrium lessons with significant
difference at .01 level.
