Abstract


This study aims to develop geometry media in Contextual Teaching and Learning to improve students' mathematical literacy. This study was motivated by the low mathematical literacy of grade IV SDN Danguk which can be seen from the results of observations, initial tests showed that students tended to be passive, did not understand the material and learning was not yet able to relate to real life. The learning process took place with lectures, already using concrete media but plain and not colored so it was not attractive. This development research used the R&D method and the ADDIE model. Geometry media was designed to be visually attractive, interactive and easily accessible. Data collection techniques used observation, questionnaires, tests and documentation. The results of the material expert validation showed that the geometry media was valid with a score of 83%, the Mendi validation got a score of 84% and the language validation was 87%. The students' response to the product got an average score of 86% and the teacher's response was 93%, both of which were in the very feasible category. Based on these results, geometry media was declared feasible to be used as teaching materials to increase motivation and support independent learning.
