Objective: To measure academic achievement of the multiple intelligence-based learning medium via a tablet device.
Material and Method: This is a quasi-experimental research study (non-randomized control group pretest-posttest design)
in 62 grade 1 elementary students (33 males and 29 females). Thirty-one students were included in an experimental group
using purposive sampling by choosing a student who had highest multiple intelligence test scores in logical-mathematic. Then, this group learned by the new learning medium via a tablet which the application matched to logical-mathematic multiple intelligence. Another 31 students were included in a control group using simple random sampling and then learning by recitation. Both groups did pre-test and post-test vocabulary.
Results: Thirty students in the experimental group and 24 students in the control group increased post-test scores (odds ratio = 8.75). Both groups made significant increasing in post-test scores. The experimental group increased 9.07 marks (95% CI 8.20-9.93) significantly higher than the control group which increased 4.39 marks (95% CI 3.06-5.72) (t = -6.032, df =
51.481, p<0.001).
Conclusion: Although learning from either multiple intelligence-based learning medium via a tablet or recitation can contribute academic achievement, learning from the new medium contributed more achievement than recitation. The new learning medium group had higher post-test scores 8.75 times than the recitation group. Therefore, the new learning medium is more effective than the traditional recitation in terms of academic achievement. This study has limitations because samples
came from the same school. However, the previous study in Thailand did not find a logical-mathematical multiple intelligence
difference among schools. In the future, long-term research to find how the new learning medium affects knowledge retention
will support the advantage for life-long learning.
