Unveiling belief and pedagogical content knowledge of prospective secondary mathematics teachers

Prospective teachers' beliefs have a beneficial effect on their knowledge and actions. Furthermore, teachers' pedagogical content knowledge is an essential contributor to teachers' impact on students' academic outcomes. However, examining how prospective teachers' beliefs influence their pedagogical content knowledge is still unclear. The current study investigates prospective mathematics teachers' beliefs and pedagogical content knowledge. We recruited three undergraduate students in the mathematics department consisting of one male and two female participants in this study. By assigning two interviews, a test, and observation, we examined three prospective mathematics teachers' pedagogical content knowledge and their beliefs about the nature of mathematics, mathematics learning, and mathematics teaching. Prospective mathematics teachers' test, interview, and observation results were analyzed in three stages: data condensation, presentation, and conclusion drawing and verification. The findings point out that traditional beliefs (instrumentalist and platonist views) are more dominant in prospective teachers' beliefs about the nature of mathematics. Moreover, the more sophisticated prospective teachers' beliefs about the nature of mathematics, mathematics learning, and mathematics teaching are, the higher one's content knowledge and pedagogical content knowledge levels are. Implications of this study, mathematics teacher educators should assist and foster prospective teachers in developing constructivist or problem-solving beliefs

HOW TO IMPROVE PROBLEM SOLVING ABILITY THROUGH LESSON STUDY?

The teacher frequently asks questions in the form of algorithms without challenging the student to think at a higher level and nearly never gives daily questions. As can be observed, some teachers have not done competency assessments and hence do not require pupils to accomplish specific competencies. The purpose of this project is to create school collaboration worksheets and examine student responses to these problems, with the goal of implementing learning through the Lesson Study for Learning Community (LSLC) method. This study employs a qualitative approach and a design research method. Design research is divided into two stages: development research and design research. The study's subjects were seventh-grade pupils from SMPN 1 Merauke. This investigation culminated in the development of worksheets on direct comparisons and integers. According to the results of the examination of students' responses to the LKS, some students were able to solve problems effectively, indicating that this LKS was legitimate and useful for us
