Development of Mathematics Mobile Learning Application on Android-based Smartphone Using Social Aritmetics

Abstract Great interest in the use of mobile phones, especially types of smartphones can be utilized in the field of education and given that most internet users are students, the development of applications to help implement learning or known as mobile learning will be a good prospect. The aim of this research is to describe the development process and produce the Mathematics Mobile Learning application on Android-based Smartphones with Social Arithmetic material in good quality. This study refers to the development model according to Plomp (2013) which consists of three stages, namely (1) preliminary research, (2) prototyping phase, (3) assessment phase. The application developed is tested in a limited way to six seventh grade students with different schools. The application developed is in the good category, because it fulfills the criteria of valid, practical, and effective. The results of the application validation developed were declared valid because it obtained a total average score of 2.96. The application developed fulfill theoretically practical criteria because the application is declared valid from the validators and empirically practical because the response questionnaire filled in by the research subject is 81.5% where based on the practicality criteria of the media, it can be stated that the application as learning media can be used without revision. In addition, the application developed also fulfills the effective criteria because all students who are subjects receive score minimum 78 so that it can be stated that the application developed is very effective.
