Abstract
Design research aims to help students' understanding of the concept of angle measurement by using measurement units. This study, using PMRI approach that produces two series of activities that support students to understand the concept of measurement in determining the angle of the angle. Implementation of these activities are designed through three stages: preliminary design, design of experiments and retrospective analysis. The resulting activity includes two activities, ie activities of students by comparing two different angles aims to determine the unit of measurement and using measurement unit for measuring large angles. The study involved 6bstudents in the experimental teaching at SDN 182 Palembang. The results showed that both activities have been carried out in stages, from the informal to the formal stages which help the students to understand the concept of measurement in determining the angle of the angle. From these results, it looks way answers the students understand the concepts used in the measurement of different angles. Students compare two different angles between large angle with a small angle to obtain a measurement unit and a large angle through a small angle as the unit of measurement. Students also conduct measurements using the size of the unit by way of laying several units large units that meet the measured angle. Keywords: angle measurements, measurement units, design research
