Abstract

          The objectives of this research were to: 1) develop the problem-based learning management plan on problem of natural resources and environment to be effective according to the 80/80 criteria, 2) compare the critical thinking ability before and after the problem-based learning management and 3) study student’s satisfaction on problem-based learning management. The sample were 35 students from Faculty of Liberal Arts, majoring in Aviation Business in North Bangkok University. They were selected by purposive sampling of registered students in SCI102: Man and Environment subject of the second semester in 2022 academic year. The research instruments were problem-based learning management plans on problem of natural resources and environment, a critical thinking ability test and a questionnaire on student satisfaction towards problem-based learning management. The data analysis statistics were percentage, mean, standard deviation, efficiency E₁/E₂ and t-test.
          The research results were as follows: 1) The efficiency of problem-based learning management plans on problem of natural resources and environment (E1/E2) was 82.86/80.93, 2) the critical thinking ability after the problem-based learning management was higher than before the learning management with statistical significance at the .01 level and 3) The students’ satisfaction on the problem-based learning management was at a high level (x̅=4.37, S.D.=0.52).
