Abstract

This descriptive study aims to describe how reflective students solving the linear programming related problems. The data were gathered from cognitive style test called Matching Familiar Figure Test (MFFT), linear programming problem solving test and interview. The participants were 22 students in a senior high school located in Pangkalan Banteng, Indonesia. From the MFFT test, it was found that 7 students were having reflective cognitive style, 8 students were having impulsive cognitive style, 4 students were having fast accurate cognitive style and 3 students were having slow inaccurate cognitive style. From those, two students with reflective cognitive styles were chosen as the subject of the study. The data were analyzed qualitatively using descriptive method. The results showed that the reflective students start to solve the problem in Understanding the Problem step by gathering information served in table. Devising a Plan step was done by explaining the steps will be executed, translating problem to the mathematical models and identify the problems to determine the objective function. Carrying Out the Plan step was done by selecting points to draw the graph, area of solution, calculating the intersection point, testing the objective function in each vertex and concluding the optimum value. Looking back was done by checking each step they performed previously.
