Mathematical justification is the process through which one's claim is validated to be true based on proper and trustworthy data. But it serves as a catalyst to facilitate mathematical discussions and communicative interactions among students in mathematics classrooms. This study is designed to investigate the effects of mathematical justification on students' problem-solving and communicative processes occurred in a mathematics classroom. In order to fulfill the purpose of this study, mathematical problem-solving classes were conducted. Mathematical justification processes and communicative interactions recorded in problem understanding activity, individual student inquiry, small and whole group discussions are analyzed. Based on the analysis outcomes, the students who participated in mathematical justification activities are more likely to find out various problem-solving strategies, to develop efficient communicative skills, and to use effective representations. In addition, mathematical justification can be used as an evaluation method to test a student's mathematical understanding as well as a teaching method to help develop constructive social interactions and positive classroom atmosphere among students. The results of this study would contribute to strengthening a body of research studying the importance of teaching students mathematical justification in mathematics classrooms.

The purpose of this study was to investigate the interaction of science PCK between two elementary school teachers by the teacher collaboration within the school. We chose the case that two teachers collaborated spontaneously in the 5th-grade science classes. Even though they had similar teaching experiences, one of them had the science PCK while the other did not. As a result of this study, two teachers began to collaborate to avoid comparisons of science classes between them. They shared the same teaching plan but practiced science teaching individually. During they taught science, they usually collaborated on the instructional sequences, student's activities, and the content of assessments. They had an in-depth collaboration when the teacher who lacked the science PCK asked help to teach problem-centered learning by science inquiry. During the collaboration, their science PCK components, especially the knowledge of instructional strategies for teaching science, shared and it affected the teacher's science practices who lacked the science PCK. However, they did not usually share the knowledge of teaching for their everyday science classes because two teachers had the perception of noninterference about their science classes. This case has the limitation that it is hard to generalize the results but teacher collaboration shows the possibility to develop the elementary school teachers' science professionalism by having peers in the school who can help them in science classes.
