Abstract:
This research aims to improve students' understanding of the Concept Group in instructions of Abstract Algebra through mathematical connection analysis. This research was conducted at the University of Papua for 32 student’s mathematics student who took the course of the algebraic structure in the academic year 2017/2018. Instruction was carried out using cooperative model, through the application of group investigation. Students were grouping based on the prerequisite lesson grades, especially introduction to mathematics. The results show that the connection between concepts provides better results on improving students' concept of understanding, compared to conventional teaching learning, where lecturers provide a formal definition, provide further examples of theorem and proof of theorem.
