Abstract

The aim of this study is to develop an Android-based learning application which is named worked example mechanics. This application was made for learning classical mechanics class IX Natural Sciences Program in Indonesia. This application is specifically designed to train and improve students' ability to draw and interprete Free Body Diagram (FBD). This application contains classic mechanic material content, animated learning of classical mechanics, drawing exercises and interpreting FBD  and a self-evaluation system. This application has passed the feasibility test of both the material and the media by Yogyakarta Negeri University physics learning experts. The app is also useful in enhancing the ability to interpret FBD, in trials at Sekolah Menengah Atas 2 Kupang/SMAN 2 Kupang (State Senior High School 2 Kupang), SMAN 3 Kupang, SMA TIMPOLMAS Kupang and State Alyah Madrasah (MAN) 1 Yogyakarta

Abstract

This research aims to diagnose the difficulties learning mathematics reviewed from numerical ability of extraordinary junior high school Karya Murni Manggaraistudents. This research was qualitative research andthe sampling technique used was purposive sampling, so the subjects were 4 of students. Data were collected using test and interview. Test was used to know the types of learning difficulties in mathematics and interview was used to know factors that cause difficulties to learn mathematics. Data were analyzed by using descriptive data analysis techniques with stages : reducing data, presentation of data, conclusion, and verification.The results of this research indicate that students are still having difficulties regarding mathematics calculations, connecting concepts in accordance with existing situation, and solve the problems. These difficulties are caused by weak memory, the material being taught is not related to the student’s daily life, and the lack of procedural, conseptual, and factual abilities. Therefore, it is necessary to find a strategy that can reduce student’s difficulties learning mathematics students and can improve student’s numerical ability.
