Mathematical problem solving skills using IDEAL model based on personality type

Abstract

Personality is one of the factors that influence the ability to solve. There are differences in problem solving abilities between students with extroverted personality and students with introverted personality. This research aims to describe mathematical problem-solving abilities using modification IDEAL model based on personality type. This research used descriptive qualitative method. The subjects of the study consisted of eight students of junior high school in Klaten. The subjects selected by purposive sampling. The instrument used to explore the ability of mathematical problem solving is a description test, followed by an interview. Based on the results of this research, it can be concluded that student's mathematical problem solving with extroverts personality is is 53% greater than students with introvert personality only 47%. Another interesting finding from this research, extrovertes students are better at planning and choosing the right solution strategy, implementing the chosen solution strategy, and intepreting the results of solutions in the form of conclusions from students with introverted personality. Meanwhile, the advantages of introverted students are in identification of problems and writing down the objectives of the problem given.
