THE EFFECT OF INQUIRY-BASED LEARNING MANAGEMENT THROUGH GRAPHIC ORGANIZER ON ANALYTICAL THINKINGABILITY AND LEARNING ACHIEVEMENT IN EARTH SCIENCE AND ASTRONOMY SUBJECT OF GRADE 10 STUDENTS

Abstract

               The purposes of this research were to compare 1) analytical thinking ability before and after learning of using inquiry-based learning management through graphic organizer, 2) analytical thinking ability of using inquiry-based learning management through graphic organizer with 70 percent of full score, 3) academic achievement before and after learning of using inquiry-based learning management through graphic organizer and 4) academic achievement of using inquiry-based learning management through graphic organizer with 70 percent of full score. The sample was 12 grade 10 students, they were selected by cluster random sampling. The research instrument were 1) the 6 lesson plans, 2) the analytical thinking ability test 18 items of 6 situation subjective tests and 3) the achievement test 30 items in 4 multiple choices. The data were analyzed by the mean, standard deviation, dependent samples t - test and one sample t–test.
The research findings were as follows:

               1) The students had analytical thinking ability post-test was higher than the pre-test score of analytical thinking ability with statistical significance at the .05 level. 2) The students had the post-test had more analytical thinking ability with 70 percent of full score with statistical significance at the .05 level. 3) The students had academic achievement post-test was higher than the pre-test score of academic achievement with statistical significance at the .05 level, and 4) The students had the post-test had more academic achievement with 70 percent of full score with statistical significance at the .05 level.
