Science Learning Management through Inquiry Method Supported with Graphic Organizers to Develop Analytical Thinking Ability of Grade 8 Students

Abstract

The purposes of this research were to 1. compare the analytical thinking ability of grade 8 students before and after using science learning management through inquiry method supported with graphic organizers, 2. compare the analytical thinking ability of grade 8 students after science learning management through inquiry method supported with graphic organizers compared with criteria of 70% and  3. evaluate the development of analytical thinking ability of Grade 8 Students after science learning management through inquiry method supported with graphic organizers. The sample of 45 students studied grade 8 of Thanyarat School, Pathum Thani Province in the second semester of the academic year 2020. The instruments used in this research consisted of Lesson Plans and the Analytical Thinking Ability Test. The quasi - experimental research method was used and the data were analyzed using means, standard deviation, relative gain score, and t – test for dependent sample. The researcher found that 1) students’ analytical thinking ability after science learning management through inquiry method supported with graphic organizers was significantly higher than before studying at the level of .05, 2) the score of students’ analytical thinking ability after science learning management through inquiry method supported with graphic organizers was significantly higher than the criteria of 70% at the level of .05 and 3) the overall results of evaluating the development of students’ analytical thinking ability after science learning management through inquiry method supported with graphic organizers with relative gain scores, the average was at the medium level.
