Development of Geogebra Assisted Learning Modules to Improve Mathematical Representation Abilities and Self Regulated Learning of Senior High School

This research aims to analyze: 1) Validity of the geogebra-assisted learning module developed; 2) Practicality of the geogebra-assisted learning module developed; 3) Effectiveness of the geogebra-assisted learning module developed; 4) Increasing mathematical representation abilities by using the geogebra-assisted learning modules that were developed; 5) Increasing self regulated learning by using the geogebra-assisted learning modules that were developed. This research is development research using the ADDIE development model. This development model consists of 5 development stages, namely analysis, design, development, implementation and evaluation. From the results of trial I and trial II it was obtained: 1) The geogebra-assisted learning module developed meets the valid criteria; 2) The geogebra-assisted learning module developed meets the practical criteria; 3) The geogebra-assisted learning module developed meets the effective criteria; 4) The mathematical representation ability using the geogebra-assisted learning module that has been developed has increased as seen from the N-gain value of 0,45, meaning it is in the "medium" category; and 5) Self regulated learning using the geogebra-assisted learning module that has been developed has increased as seen from the N-gain value of 0,42, meaning it is in the "medium" category.
