Two Parts of Reflective abstraction: For New Problem Solving and Mathematical Concept

Abstract

This research aimed to describe the reflective abstraction exhibited by each of part of reflective abstraction. The research question was about How is students'reflective abstraction in reflecting their prior knowledge into higher thought and reorganizing the new mathematical concept. We performed a qualitative research approach with a study case design as the research method. This study involved 36 11th grade students and 36 12thgrade students. The data was analyzed qualitatively by using hyperRESEARCH application. The first part of the students' reflective abstraction could be seen from how the students developed the concept of mathematical problem solving on the mathematical problem testing, while the second part of the reflective abstraction could be seen on the process of developing core concepts of mathematics learning.
