The development of problem-based learning management of the learning unit on the process of weather change for Matthayomsuksa 1 students.

Abstract

          This research aimed 1) to develop problem-based learning management of the learning unit on the process of  weather change for Matthayomsuksa 1 students to achieve the efficiency criteria of 75/75, 2) to compare learning achievement in the learning unit on the process of weather change for Matthayomsuksa 1 students between before and after learning, based on problem-based learning management, 3) to compare critical thinking of Matthayomsuksa 1 students between before and after learning, based on problem-based learning management. The sample is 20 Matthayomsuksa 1 students of the academic year 2022, selected from Cluster random sampling technique. The research instruments are 1) problem-based learning management plan, 2) critical thinking measurement, 3) learning achievement measurement. Basic statistics for data analysis are arithmetic mean, standard deviation, and dependent t-test. The research results revealed as follows:

1. The efficiency / of the developed problem-based learning management plan of the learning unit on the process of weather change for Matthayomsuksa 1 students was 77.38/76.5 which met the set criteria of 75/75.
2. The learning achievement in the learning unit on the process of weather change for Matthayomsuksa 1 students after learning was higher than before leaning with the statistical significance level of 0.05.
3. Critical thinking of students based on the problem-based learning management plan for Matthayomsuksa 1 students after learning was higher than before learning with the statistical significance level of 0.05.
