Abstract

This quasi-experimental study aimed to develop and examine the effectiveness of microlearning media (MLM) on the topic “Using Basic Chemical Instruments in Agriculture” for first-year undergraduate students in the Department of Agricultural Education, School of Industrial Education and Technology, King Mongkut’s Institute of Technology Ladkrabang, during the first semester of the 2025 academic year. The sample consisted of 50 students selected through purposive sampling and taught using the one-group pretest–posttest research design. The research instruments included the developed MLM, a media quality evaluation form, a media efficiency evaluation form (E1/E2), and pretest–posttest achievement tests. The overall quality of the MLM was rated at a very good level ( $\bar{x}$ = 4.60, SD = 0.39), with the content quality receiving a very good rating ( $\bar{x}$ = 4.76, SD = 0.43) and the technical quality also rated at a very good level ( $\bar{x}$ = 4.44, SD = 0.31). The media efficiency score was 96.80/84.40, surpassing the standard criterion of 80/80. The comparison of learning achievement before and after using the MLM revealed that the posttest mean score ( $\bar{x}$ = 16.88, SD = 2.92) was significantly higher than the pretest mean score ( $\bar{x}$ = 6.90, SD = 1.38) at the .05 level of significance (t = 25.24, p < .001). These findings indicate that the developed microlearning media met quality and efficiency standards and effectively enhanced students’ understanding and practical knowledge regarding the use of basic chemical instruments in agricultural contexts, demonstrating its potential as a suitable instructional tool for improving learning outcomes in agricultural education.
