Comparison of Science Process Skills and Learning Achievement of Grade 9 Students on the Topic of Life and Environment and Natural Resources by Using the Principles of Sufficiency Economy and Conventional methods

Abstract

The purposes of this research included the following: 1) to compare the science process skills, 2) to compare the learning achievements, and 3) to compare the satisfaction of students who learn by using the principles of sufficiency economy and conventional methods. The sampling groups were 2 classes from grade 9 students who studied in the second semester of 2018 academic year at Kudbongpitthayakan School. Cluster random sampling was used for dividing experimental and control groups. There are five assessment instruments used in this study: 1) the lesson plans of sufficiency economy principles, 2) the lesson plans of conventional methods, 3) the science process skill test, 4) the academic achievement’s test, and 5) the satisfaction questionnaire with learning activity. The mean, standard deviation, and t-test for independent samples were used for data analysis. The results found that 1) the scores of science process skills were not statistically significant different between the experimental and the controlled groups. 2) the academic achievements of the experimental group was statistically significant higher than the controlled group at .05 level, and 3) the satisfaction of the experimental group was statistically significant higher than the controlled group at .05 level.
