Abstract

Mathematics can be represented by many forms such as symbolical, verbal, graphical, or tabular representations. To understand mathematics concepts is by connecting or translating all kind of mathematics representations. Therefore, mathematics teachers should facilitate students to translation all kind of mathematics representations. This article discusses the research results which investigated how mathematics teachers implement their teaching which facilitate students to translation mathematics representations. Data were collected by questionnaire, documentation, and observation. Sample of the research were 91 mathematics teachers of junior and senior high schools from some regions of South Sumatera and Bangka Belitung. The research results show that mathematics teachers have already implemented mathematics representation properly, however representations used by the teachers were not variably, which means translations between representations were not implemented yet. By comparing all mathematics representations, the symbolical representation was the most frequently used in teaching and learning. Mathematics teachers whom did not or poorly implemented mathematics representations in their teaching considered the national examination not requiring variation of the representations.

Abstract

The development of the PISA framework from year to year is increasingly focused on problem solving. This indicates that problem-solving ability is crucial. Considerable studies at the international level on the influence of PISA implies that the world also indirectly focuses on problem-solving abilities. The National Council of Teachers of Mathematics (NCTM) mentions five basic mathematical skills, one of which is problem solving. Mathematical modeling is one of the stages of mathematical problem solving. For that, mathematical modeling problems are chosen so that student can train problem solving ability. This study aims to describe problem solving ability of junior high school students in solving mathematical modeling problems. The result of mathematics problem solving test in grade VII students at SMP Negeri 1 Palembang has three categories, that is students with problem solving ability of mathematical well, enough, and less. The lowest occurrence of the problem solving indicator is the first indicator that is to explore and understand mathematics problems.
