ab: Summary: 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.
