Abstract

This study aims to: 1) develop an interactive book learning media based on a realistic mathematical approach to the valid, practical, and effective flat-sided geometry material (cubes and blocks) so as to improve students' mathematical spatial abilities; 2) improve students' mathematical spatial abilities by using interactive book media based on a realistic mathematical approach to the material of flat side shapes (cubes and blocks). This research is a development research. The development model used in this study is the ADDIE model with 15 students in class VIII-1 and 15 students in class VIII-2 at SMP IT Ikhwanul Muslimin as the research subject. 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 mastery of the students' mathematical spatial ability in the second trial was 86.67% (13 students). The average percentage of students' achievement in the ideal time of activity in the second trial for three meetings was 24.07%, 28.70%, 26.39%, 11.11%, 6.48%, and 3.24%. The average student response in the second trial was 3.74 (category "Interested"). Keywords: Interactive Digital Book, Realistic Mathematics Approach, Spatial Ability, Development of Mathematics Learning Media, Cubes and Blocks.

Highlights

PRELIMINARY Mathematics is one of the basic sciences that has a very important influence in life, because it can prepare and develop students' ability to think logically, kindly, and appropriately to solve problems that occur in their daily lives (Noviani, Syahputra, and Murad, 2007). 2017)
Asih (2018: 2) which states that geometry is one of the branches of mathematics that must be mastered by students because geometry supports many topics in order to solve problems in mathematics that will be useful in the process of solving mathematical problems
That students will be easier to understand, not just understanding routine problems. It is stated in the research of Arifin, Pujiastuti, and Sudiana (2020: 71) that learning media can improve mathematical spatial abilities caused by several things, namely: (1) By using this learning media students can manipulate real objects, namely manipulating objects that are physical and can be a learning experience for students; (2) the learning steps contained in the guidebook www.iiste.org use the STEM approach so that learning is linked between each STEM element so that it becomes more meaningful; and (3) the learning media developed in their activities do not provide information about the material directly, but require students to seek knowledge by exploring their learning media and building students' knowledge independently

Introduction

PRELIMINARY Mathematics is one of the basic sciences that has a very important influence in life, because it can prepare and develop students' ability to think logically, kindly, and appropriately to solve problems that occur in their daily lives (Noviani, Syahputra, and Murad, 2007). 2017). That students will be easier to understand, not just understanding routine problems Likewise, it is stated in the research of Arifin, Pujiastuti, and Sudiana (2020: 71) that learning media can improve mathematical spatial abilities caused by several things, namely: (1) By using this learning media students can manipulate real objects, namely manipulating objects that are physical and can be a learning experience for students; (2) the learning steps contained in the guidebook www.iiste.org use the STEM approach so that learning is linked between each STEM element so that it becomes more meaningful; and (3) the learning media developed in their activities do not provide information about the material directly, but require students to seek knowledge by exploring their learning media and building students' knowledge independently. Based on the description above, the authors are interested in conducting research related to learning media, realistic mathematics learning approaches, and students' spatial abilities entitled "Development of Interactive Digital Book Learning Media Based on Realistic Mathematics Approaches to Improve Students' Spatial Ability at SMP IT Ikhwanul Muslimin"
