A lesson study to foster prospective teachers' disposition in STEM education

Fostering students' dispositions may start with their interest to the topic then spread to another indicator such as persistence, contextual applications, etc. In many conditions, technology can attract students' interest and turning complexity into a lot easier problem. Therefore, prospective teachers must first be equipped in the use of the latest technology. However, the use of technology in learning must be designed appropriately. Since excess use of technology may negate someone thinking process, even though thinking is every learning main porpose. This research aim to design the apropriate integration between the learning and technology to foster prospective teachers' mathematical disposition. POM-QM represents technology embedded for the Science, Technology, Engineering, and Mathematics (STEM) learning process. In the conduct, this lesson study starts with planning the chapter design to integrate the technology into learning. Inside the learning implementations, several observers assigned for each group of students to record every activity. From both cycles reflection phase, the chapter design is able to foster students' interests, contextual awareness, and their appreciation into the topic. Continuous treatment is needed until the dispositions occurs frequently.
