Mathematical Literacy of Students Who Have High Mathematical Disposition in Solving PISA-Like Mathematics Problems

Abstract

This research aims to describe the mathematical literacy skills of students who have a high mathematical disposition in solving problems similar to PISA. The research methods in this study use qualitative descriptions. The subject of the study was a student of class IX D junior high school IT Nur Hidayah Surakarta consisting of 29 students. Of the 29 students taken 2 students who had a high mathematical disposition which was then established as a research subject. The instruments used are mathematical disposition questionnaire instruments, literacy test instruments and interview guidelines. Data analysis using mathematical literacy indicators based on research results that have a high mathematical disposition is able to solve mathematical literacy problems up to level 5 with the right and correct procedures and strategies. The subject is able to mention the information in the problem and then connect it to the problems that occur in everyday life. The subject is also able to understand the concept so that the steps of the workmanship are based on mathematical reasoning. At level 6 the subject does not understand the meaning of the problem but at this level the subject already has a strong determination to complete so as to produce a final answer that is accompanied by reason although still not accurate. Subjects with a high mathematical disposition are able to communicate results as well as reasons very well and confidently.
