Mathematical Communication and Conceptual Understanding Student’s Ability in Math by the Approach of GeoGebra Substitution Eliciting Activities (MEAs)

Abstract

This study aims to determine whether the learning Model Eliciting Activities (MEAs) approach influences students' ability to understand concepts and mathematics communication. This research is an experiment with post-test only control group design in a population consisting of 132 students from junior high school which spread over 4 classes. Sampling used cluster random sampling and assigned classes VIIIA and VIIIC as the research sample. Data in the form of concept understanding data were collected by essay test and students' mathematics communication data were collected using a questionnaire respectively, then they analyzed using The Manova test with significance level of 5%. The analyzed result show that the value of Wilk Lambda’s F equal to 5, 6565 with the significance value of 0.023. It is lower than the significant value 5%. Thus, the H₀, is rejecting. The results of this experiment indicate that Model Eliciting Activities (MEAs) approach influences students' ability to understand concepts and mathematics communication.
