Mathematics communication is one of important abilities about conveying ideas in writing and orally which measured by providing open-ended questions to solve. One of factors which influenced it is reflective-impulsive cognitive style. The purpose of this study describes the mathematics communication of a reflective and an impulsive junior high school student in solving open-ended questions. This research is a descriptive study with a qualitative approach. Data collected through test and interview. Subject was selected using purposive sampling. The results showed reflective students did written mathematics communication fluently, completely and tend to be accurate, but her oral communication tends to be influent, inaccurate and incomplete. Meanwhile, impulsive students did written communication fluently, completely but inaccurately, but her oral communication is fluent, complete, tends to be inaccurate.
Developing mathematics communication, especially in writing is needed considering that communication is one of the objectives of learning mathematics which can describe students understanding so that effective strategies are needed to develop it. One of problem solving strategies that can measures written mathematics communication is solving the analogous problem. This research aims to describe the analogous problem in developing mathematics communication especially in written communication. This research was a qualitative type through a student-written test about solving target problem using analogous problems and interview. The result showed solving analogous problems gave students understanding to be able to do the target question correctly also easier than before and it effected students could communicate the correct solutions accurately, effectively and completely in writing. So it can be said that solving analogous problems develops written mathematics communication ability of student effectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
