Analysis of Eight Grade Students Performance in Solving Mathematical Representation Problems

摘要

This research is conducted to contribute in improving students' achievement in Mathematical Representation Ability (MRA) and their performance in solving MRA problems. Those involved as samples are 316 students from Public Junior High School (PJHS) 1, PJHS 2, and PJHS 4 District Deli Serdang, and PJHS 17, PJHS 19 Medan City. Joyful Problem-based Learning (JPBL) is implemented to attain the purpose of the research. Students' achievement in MRA is measured through MRA test scores. The scores is analyzed through Student-t test at 0.05 significant level. Students' performance in solving MRA problems is analyzed descriptively. Results of the research: (1) Students in JPBL class get better MRA achievement than their counterpart in conventional one, (2) The students' performance in solving MRA problems is better in JPBL class than that of their counterpart in Conventional one. The students faced the difficulties in two aspect of MRA: Present the problem in figures and give explanation, especially related to graph and table. Meanwhile, the students' performance is best at the aspect of present the problems in mathematical equation, (3) MRA of the students in JPBL class significantly improved.
