This research comes from an idea that algebraic
thinking is one of the important things in learning mathematics for elementary
school students. Algebraic thinking ability is a transitional process from
arithmetic learning to algebraic learning. Students in elementary school must
have aquired this ability as some prerequisite for advanced mathematics (at the
level of junior high school). Aside from
that, the Algebraic Thinking ability requires students to solve mathematical
problems. The main purpose of this research is to describe students’ algebraic
thinking ability based upon algebraic-thinking characteristics, knowing the
learning trajectory of learning barriers to overcome these obstacles.
Therefore, the researcher conducted the research by utilizing a descriptive
research method. The data were collected by means of test, interview and
questionnaire on students in upper grades of elementary school located in urban
areas, mid areas, also transitional regions.
Based on the analysis of the results of algebraic thinking ability
instrument test from 78 students, and having compared with the indicators of
algebraic thinking in upper grades of elementary school in Indonesia, it shows
that algebraic thinking skills of upper elementary grades in Indonesia are seemingly
less good. In addition, researchers classify the barriers of algebraic thinking
into three types, namely ontogenic obstacle, didactic obstacle, and
epistemological obstacle, therefore with the data, the researcher generates hypothetical
learning trajectory to cope with the obstacles of algebraic thinking. Learning
trajectory as a result of this study will be developed as algebraic thinking
design learning.
