The Development of Sciences Learning Activities Based on Constructivist Theory to Enhance Science Process Skills, Scientific Mind and Learning Achievement on Momentum and Collisions Learning Unit of Grade 10th Students

Abstract

This research aimed to 1)  study of learning achievement on Momentum and Collisions Learning unit, Science Process Skills and Scientific Mind of the students in grade 10^th on Constructivist Theory 2)  compare learning achievement on Momentum and Collisions Learning unit and Science Process Skills of the students in grade 10^th  before and after the lessons on Constructivist Theory 3)  compare learning achievement on Momentum and Collisions Learning unit after the lessons on Constructivist Theory against a 70 percent criterion. Sample group in this research were 40 students of grade 10^th from a science-math program in Packchong 2 School, Packchong, Nakhon Ratchasima Province in the academic year 2016 from Research cluster random sampling. Research tools were 5 Constructivist Theory plans, 15 hours. Data was collected by 1)  a test on learning achievement 2)  a test on Science Process Skills and 3)  a test on Scientific Mind. Statistics used for data analysis was percentage, mean, standard deviation and t-test. Research findings showed that  1)  Result of learning achievement on Momentum and Collisions learning unit before the lessons Constructivist Theory of the students in grade 10^th was 8.23, that was counted at 32.90 percent and standard deviation was 2.08, ranging 4-14. After learning unit, the average score was 18.35, that was counted at 73.40 percent and standard deviation was 2.35, ranging 12-23. Their average improvement were 10.13 that was counted at 40.50 percent and Learning achievement after the lessons on Constructivist Theory was higher than before the lessons and higher than the 70 percent criterion with statistical significance at the .05 level. 2)  Result of Science Process Skills before the lessons on Constructivist Theory of the students in grade 10^th was 25.03, that was counted at 36.80 percent and standard deviation was 3.30, ranging 19-37. After learning unit, the average score was 42.68, that was counted at 62.76 percent and standard deviation was 6.90, ranging 27-59. Their average improvement were 17.65, that was counted at 25.96 percent and Science Process Skills after the lessons on Constructivist Theory of the students in grade 10 response was higher than before the lessons with statistical significance at the .05 level.   3)  Result of Scientific Mind after the lessons on Constructivist Theory of the students  in grade 10^th was 91.52,      that was counted at 76.25 percent and standard deviation was 0.71, ranging 72-112.
