Teaching materials that support future needs in the learning process require students to understand scientific concepts more contextually. Synergy is needed from the less-than-optimal learning system, teacher competence, student motivation, facilities and infrastructure, and the learning atmosphere which is built. It is essential to describe the need for teaching materials that are able to build problem-based learning concepts to see the readiness of teachers in providing representative teaching materials. The research method is a case study by collaborating qualitative and quantitative research in order to measure the absorption of information in the classroom. This study used a sample of teachers and prospective teachers in the fields of science, humanities, and social affairs. The results showed that case study as a learning approach and teaching material development was able to increase student sensitivity in responding to learning conflicts that occurred in the classroom. Furthermore, students are also trained in critical and analytical thinking skills to find solutions to learning problems found through the development of problem-based teaching materials. The sensitivity of prospective teachers is needed to optimize the four skills of teachers, especially pedagogy, which is the ability of prospective teachers to manage a learning process or teaching and learning interactions with students.
