Abstract
The purpose of this research was to enhance a mathematical representation of Mathayomsuksa 4 students through learning activities based on five practices. The participants were 37 students in Mathayomsuksa 4, Semester 2, the academic year 2020, at an large particular school in Nakhon sawan province. It took 11 hours for learning activities. The tools used in the research were four lesson plans, activity sheets, and a test on a mathematic representation. All research tools were checked for appropriateness by three experts. The data obtained were analyzed using analytic scoring. Mathematical representation was separated into three processes including 1) representation for understanding the problem, 2) representation for problem solving processes, and 3) representation for concluding the problem. The basic statistic tools used in this study were frequency and percentage.
The findings revealed that most of the students for 64.57 percent were at a good level of mathematical representation. In other words, they can draw and mark to understand the problem, identify the information and asked question, represent their idea through mathematical symbolism before problem solving processes, and use graph and equation to support their explicit and reasonable answers.
