Abstract
Chemistry learning that has been going on all this time is still monotonous, where the teacher explains the materials which are then followed by giving assignments. This learning has not been able to improve students^ learning outcomes effectively. The loading of case studies into chemistry textbooks is one of the efforts to improve students^ learning outcomes. This study aimed to describe the effectiveness of the case study-based chemistry learning textbook in improving students^ learning outcomes. The type of research carried out is a quasi-experiment. The population of this study was the eleventh-grade students of Natural Sciences at SMAN 6 Denpasar Bali. The samples were selected by cluster sampling technique to obtain a control group and an experimental group. Students in the control class were taught with the conventional chemistry learning textbook, while students in the experimental group were taught with the case study-based chemistry learning textbook. Data of students^ learning outcomes were collected by a test. Data were then analyzed by using statistics of analysis of covariance. The results of this study indicated that the case study-based chemistry learning textbook was more effective in improving the students^ learning outcomes than the conventional chemistry learning textbook.
