Learning Package Development of ‘SC 30211 Additional Chemistry 1’ Course to promote Analytical Thinking, Advanced Scientific Process Skills and Scientific Attitudes for 4th Level of Secondary Education Students, Scientific Genius Classroom Program, Nongsanhophittayakom School, Sam Ngam District, Phichit Province

Abstract

This research aims at developing a learning package to be meet 80/80 efficiency criterion, evaluating the index of effectiveness of learning package, comparing academic achievement, comparing critical thinking and advanced scientific process skills before and after adopting the learning package, and studying scientific attitudes after adopting the learning package for ‘SC 30211 Additional Chemistry 1’ course. The target group of 40 students under 4^th level of secondary education in Scientific Genius Classroom Program, Nongsanhophittayakom School, Sam Ngam District, Phichit Province who enrolled in 1^st semester of academic year 2019 is chosen from purposive sampling. Research instruments include a learning package, learning plan, academic achievement test, analytical thinking test, test of advanced scientific process skills and test of scientific attitudes. Statistics for data analysis include average, standard deviation and dependent t-test. Research findings are as follows. The learning package gains the efficiency score (E₁/E₂) of 83.54/81.41 and effectiveness index (E.I.) of 0.6119. Students who studied with the learning package have higher post-study academic achievement than before studying, at the statistically significant level of .05. Students who studied with the learning package have significantly higher post-study critical thinking and advanced scientific process skills than before studying, at the statistically significant level of .05. Students have overall scientific attitudes at the highest level ( = 4.68, S.D. = 0.50).
