Abstract

This research is motivated by the difficulties of elementary school students in understanding geometric concepts, especially geometrical materials, namely cubes and blocks. Based on the preliminary study, there are still many fifth grade elementary school students who still have difficulty in developing mathematical reasoning and creative thinking skills when studying the concept of geometric figures, so that geometry material is considered the most difficult material to learn. This study aims to analyze and explore learning obstacles on mathematical reasoning and creative thinking skills in understanding the concept of cubes and blocks in order to produce a didactic design in the form of a Hypothetical Learning Trajectory (HLT) based on Realistic Mathematics Education (RME). This research was a qualitative research with a Didactical Design Research (DDR). The sample of this study was 20 students of 5th in Two Elementary Schools in Tasikmalaya Regency. The data was collected by observing, mathematical reasoning and creative thinking skills test on the concept of cubes and blocks, interviews, and documentation. Based on the test of cube and block material, the test results obtained that the average percentage of 65% of students on concept difficulty, the average percentage of 80% of students on difficulty in using data, the average percentage of 70% of students on difficulty in interpreting data, and the average percentage of 100% of students on the difficulty of drawing conclusions. An alternative solution that can be applied is to make a didactical design for students^ mathematical reasoning and creative thinking skills on the concept of cubes and blocks in the form of a Hypothetical Learning Trajectory which will be investigated in further research.
