Abstract :

Higher education plays a strategic role in developing the intellectual life of the nation and is part of the national education system. Chemistry learning should not only focus on mastering concepts but also on students’ ability to apply these concepts in real-world contexts through problem-solving skills to meet the challenges of the 21st century. This research aims to develop a case-based learning-oriented textbook that can train prospective teacher students’ chemistry problem-solving skills. This research method used Research and Development (R&D) as proposed by Borg and Gall, limited to the development stage. Data collection used non-test techniques, seeking validation from three subject matter and pedagogical experts. Quantitative descriptive statistics were used for data analysis. The validity test results showed that the case-based learning-oriented textbook was valid, with an Aiken validity index of 0.87 (high validity). Furthermore, the textbook can be used as a means to facilitate student learning activities in case-based learning to train prospective teacher students’ chemistry problem-solving skills, so that the function of this textbook can be maximized.
