DEVELOPMENT OF PROBLEM-SOLVING ABILITIES AND LEARNING ACHIEVEMENT OF MATHAYOMSUKSA 5 STUDENTS ON THE TOPIC OF ELECTRICITY USING STEM EDUCATION LEARNING MANAGEMENT AND MIND MAPPING

Abstract

The purposes of this research were: 1) to develop the lesson plans on the topic of electricity based on STEM education learning management and mind mapping to meet the efficiency of 80/80, 2) to compare students’ problem-solving abilities before and after the intervention, 3) to compare students’ learning achievement before and after the intervention, and 4) examine the student satisfaction with the developed learning management based on STEM education and mind mapping. The sample, obtained through cluster random sampling, consisted of 30 Mathayomsuksa 5 students studying at Phonngamsuksa School under the Secondary Educational Service Area Office Sakon Nakhon in the first semester of 2023 academic year. The instruments included five lesson plans, a problem-solving abilities test, a learning achievement test, and a satisfaction questionnaire. The statistic for data analysis were mean, standard deviation, percentage, and t-test for Dependent Samples.

The results of this study were as follows: 1) The developed lesson plans based on STEM education and mind mapping on the topic of electricity achieved an efficiency of 80.58/83.05, which was higher than the set criteria of 80/80. 2) The students’ problem-solving abilities after the intervention were higher than those before the intervention at the .01 statistical significance level. 3) The students’ learning achievement after the intervention was higher than that before the intervention at the .01 statistical significance level. and 4) The student satisfaction with the developed learning management was rated at the highest level of mean score of 4.61.
