Development of Flip Book Learning Media Based on a Scientific Approach to Improve Reasoning and Understanding Ability Student Mathematics Concepts

Abstract

This study aims to: 1) see the quality (valid, practical and effective) of flip book learning media that was developed to improve students' reasoning abilities and understanding of mathematical concepts; 2) improve students' reasoning abilities and understanding of mathematical concepts through flip book learning media developed. This research is a development research. The development model used in this study is the ADDIE model with 29 students in class VII-A and 23 students in class VII-B at SMP Harapan 1 Medan. The validity of the learning media developed was reviewed from the analysis of the results of the validity of the learning media by the validators with a total average value of 3.73 ("Valid" category). Meanwhile, The practicality of learning media is seen from the observation score of the implementation of learning in the second trial, which is 3.73 (category "Well Implemented"). The effectiveness of learning media in terms of four aspects, namely classical completeness, student activity observation scores, and student responses. The classical completeness of students' reasoning abilities and understanding of mathematical concepts in the second trial was 87% (23 students). The average percentage of students' achievement in the ideal time of activity in the second trial for three meetings was 21.8%, 19.2%, 21.5%, 26.0%, 9.8%, and 1.8%. The average student response in the second trial was 91.6% (category "Interested"). Based on the normalized gain index, it was found that in the second trial there was an increase in the score with a score of 0.4 (the "medium" criterion). The effectiveness of learning media in terms of four aspects, namely classical completeness, student activity observation scores, and student responses. The classical completeness of students' reasoning abilities and understanding of mathematical concepts in the second trial was 87% (23 students). The average percentage of students' achievement in the ideal time of activity in the second trial for three meetings was 21.8%, 19.2%, 21.5%, 26.0%, 9.8%, and 1.8%.
