Promoting understanding ability of semigroup concept through learning model of concept attainment

Abstract

This study aimed to improve the ability of the understanding of semigroup concept through Concept Attainment Model. The method of this study is quasi experiment. The design of this study is using one group pre-test & post-test design. Sample of the study is 34 students of mathematics pre-service teacher at Abstract Algebra course. Instrument used in this study is a test about semigroup concept which contain 4 items. Data were analysed qualitatively and quantitatively. This study found that the improvement of students' ability of the understanding of semigroup concept was 0.68, (medium category) and the achievement of of the concept understanding ability of semigroup was 75.44 (high category). Thus, concept attainment learning model was effective in developing the ability of the understanding of the students about semigroup concept.
