Abstract

This research aims to produce a learning trajectory and analyze the angle measurement material using the context of gymnastic movements. The method used in this study was a design research method with the type of validation studies with the PMRI (Pendidikan Matematika Realistik Indonesia) approach. The subjects in this study were pre-service elementary school teachers, totaling six people in the pilot experiment and 24 people in the teaching experiment. Data collection techniques using tests, observation, and documentation. Data were analyzed descriptively on test results, observations, and documentation obtained. The results of this study are in the form of material design, and the results of an analysis of angle measurements using the context of gymnastics in the angle measurement material about angle sizes, angle shapes, and types of angles form a learning trajectory. Gymnastic movements are viewed from the movements of the hands, feet, and limbs that form acute angles, right angles, half-full turns/straightened angles, one complete rotation angle, and reflex angles. The resulting angle varies from 200 to 3500.
