Abstract
Husnuz Zaimah zaimah335@gmail.comMathematics teacher of MTsN 2 Mojokerto, East JavaAbstract: Social Arithmetic discusses buying and selling material. To achieve the description of the practice of buying and selling can be easily understood by students through the use of comic media. The purpose of this research is to develop learning media in the form of comics about buying and selling practices on MTsN 2 Mojokerto Social Arithmetic material. The development procedure was adapted from the theory developed by Borg & Gall (1983) through 9 stages, namely (1) conducting research and information gathering, (2) conducting planning, (3) developing initial product formats, (4) design validation, (5) ) revising design validation, (6) major field trials, (7) revising products, (8) conducting operational field tests, (9) conducting product effectiveness tests; (10) Revision of the final product. The results of the comic media analysis of learning buying and selling practices show the validation score of the material expert is 96% and the media expert is 93.6%. Trial of 17 students 82.30% and 34 students 92.31%. From the effectiveness test the average value of the control class is 48.5 while the trial class is 76.91. T-test significance test showed 0.01. The data above shows that the learning comics media of buying and selling practices is said to be feasible to be used in the learning process of Social Arithmetic material Keywords: development, comic media, buying and selling practices
Highlights
Formulation of mathematical discussion is not limited to determining relations, patterns, shapes and assemblies as targets
This study is a type of research and development (R&D)
There are 7 stages performed in this study namely: (1) initial study and gathering information, (2) planning, (3) developing the initial product, (4) limited field trial, (5) revising the initial product, (6) field trials, and (7) revision of the final product
Summary
Formulation of mathematical discussion is not limited to determining relations, patterns, shapes and assemblies as targets. These four goals only emphasize that mathematics involves abstract ideas. Hudoyo (2013) stated that learning mathematics is a high mental activity. It should be noted that the activities or things students learn must be something interesting and challenging. As stated as one of the principles in school mathematics in the National Council of Mathematics Teachers, when learning is challenging, students will be confident to solve math problems and to understand new knowledge (NCTM, 2000). Learning media is one thing that can challenge and attract students' attention in learning mathematics
