DEVELOPMENT OF ABSTRACT ALGEBRA TEACHING MATERIALS BASED ON ABDUCTIVE-DEDUCTIVE STRATEGY

Abstract

This paper presents the results of research and development on abstract algebra teaching materials based on abductive-deductive strategy that applied in three steps. The first stepsare literature study, designing and developing teaching materials, expert validation, and revision. The second step is limited tests of eight students randomly selected. This test used the single-shot case study experimental design. The third step, product testing, conducted on a group of samples consisting of twentysix students. The method used in the third step is before-after experimental design. The instruments used are validation sheet, mathematical proof test, and performance effectiveness sheet. The data are analyzed using Wilcoxon Sign-Rank Test at 5% significance level and descriptive analysis. The results showed that the abstract algebra teaching materials based on the abductive-deductive strategy already meet the valid, effective, and practical criteria. It can be used in abstract algebracourses.
