Pengembangan Instrumen Tes Kemampuan Representasi Matematis dalam Materi Persamaan Garis Lurus di SMP

Abstract

The purpose of research is to develop test instrument to measure the ability of mathematical representation in equations with two variables in Junior High School. The methodology that use is a research and development. The first phase in this research is self-evaluation, in the next phase is one-to-one pilot which run in parallel with experts review. Then pilot field in the small group phase and the last is field test phase. Qualitative data analisys is used in the beginning phase (one-to-one and experts review), while quantitave data analisys is used in the pilot field (small group and field test). The research results in the form of a set the test instrument that decent used to measure the ability of mathematical representation based on the result of experts review, included the ability of translation and transformation. While the test instrument quality about the ability of translation is not good because doesn't satisfy the criteria have been set, and the test instrument about the ablity of transformation has a good quality
