Abstract

The purpose of this study is to evaluate the effectiveness of the application of inquiry modules with cognitive conflict strategies in chemical bonding material in improving students' critical thinking skills. This research is a quantitative descriptive study that was carried out with the design of one group pretest posttest. The sample used was 26 students who took general chemistry courses with a purposive sampling technique. Data were analyzed by normalized N-gain method and paired samples t-test. The result of this study showed that average N-gain of student critical thinking skill after application of inquiry modules with cognitive conflict strategies is 0.6 with medium category. Average score of student critical thinking skill after treatment (74,12) is significantly higher than before (35,77) that proved by t statistic (41,09) higher than t critic (1,71) with df = 25 and p = 0,000 on one tail t-test. Therefore, it was concluded that the application of inquiry modules with cognitive conflict strategies enhance student critical thinking skill on chemical bonding material learning effectively.

Abstract

Studying hydrocarbon material requires ability in problem solving so students are able to identify, analyze, and describe abstract chemical concepts and principles into concrete. The purpose of this study was to the improving of students' hydrocarbon problem solving abilities through the SAVI learning model assisted by puzzle media. The research design used in this study was pre-experimental with a research design namely One Group Pretest-Posttest Design.The study was conducted at SMAN 7 Mataram, Jl. Adi Sucipto, Ampenan Utara, Kec. Ampenan, Mataram City, West Nusa Tenggara. The subjects of this study were students of class XI Science. The research instrument include syllabus, lesson plans, worksheets, and multiple choice test items. Data were analyzed using the N-Gain test to find out the increased ability to solve hydrocarbon problems. The results showed that the level of N-Gain was in the range of 0.33 with a moderate category which meant an increase in students' problem solving abilities after using the SAVI model assisted by puzzle media. Thus, it can be concluded that students' problem solving abilities can be improved through the application of SAVI learning models assisted by puzzle media.
