Abstract:
The purposes of this research were to study the effectiveness of inquiry-based learning using a computer assisted instruction on achievement in chemistry and to study satisfaction level of students after studying through the computer assisted instruction. The participants of this research were grade 11th students who studied in the second semester of academic year 2016 at Saensuk School. They were selected by the cluster random sampling. These students were divided into 42 students were put in an experimental group and 41 students were in a control group. The research instruments were computer assisted instruction, lesson plans using the inquiry-based learning with computer assisted instruction, lesson plans using the inquiry-based learning,
a chemistry achievement test, and a satisfaction questionnaire. The data was analyzed by using mean, standard deviation, and two-way repeated measure ANOVA.
The results of this research showed that:
1. The computer assisted instruction on the topic of elements and inorganic compounds in industry had an efficiency of 82.98/ 81.90 which was in accordance with the criterion standard of 80/ 80.
2. The posttest of the learning achievement after learning using inquiry-based learning with CAI was statistically significant higher than the pretest at the .05 level.
3. The posttest of the learning achievement after learning with inquiry-based learning with CAI was statistically significant higher than the posttest of learning with inquiry-based learning at the .05 level.
4. Students were satisfied with the inquiry-based learning with CAI at a high level
