Pengembangan media pembelajaran berbantuan komputer berbasis RME untuk siswa SMP kelas VII pada materi perbandingan

This research and development is motivated by student’s difficulties in learning proportion material especially in determining the direct and inverse proportion material. The students are difficult to distinguish problem about direct and inverse proportion material. Moreover, at this time there has been no development of computer assisted learning media based RME on direct and inverse proportion material. This development aims to produce a computer assisted learning media on direct and inverse proportion material which are valid, practical, and effective. The result of research and development is “GO!MATH” courseware in the form of executable file in CD that can be use independently by students both in classroom or at home. This research and development is done by adapting Thiagarajan development model which only up to the third stage, because the stage develope due only for limited testing stage. The limited testing in this research involved nine student of SMP Brawijaya Smart School Malang which has heterogeneous ability. The results show that “GO!MATH” are valid, practical, and effective.

Computer Assisted Learning Media and Decimal Board: How it Impact on Elementary Students’ Concept Mastery?

The lack of students' mastery of decimal fractions has become a current issue among researchers. The comparisin of decimal fraction values was still an obstacle for students. The use of learning media in this study is the Computer Assisted Learning Media and Decimal Board can be a solution to these problems. This study aimed to describe the increase of elementary students’ concept mastery on decimal fractions subject matter. Descriptive-quantitative method with pre-test and post-test was carried out to achieve the research objectives. The subjects in this study were the 4th grade students (22 students) in the East Lombok area. The students' concept mastery was measured using a multiple-choice test instrument of 10 items. The research data were analyzed descriptively and statistically using paired sample t-test. The results showed that students' concept mastery increased after learning (pre-test: 54.5%; post-test: 77.27%). The results of statistical tests using the paired sample t-test also showed that students' concept mastery had increased significantly after learning (p < 0.05). Based on the results of the study, it can be concluded that learning using Computer Assisted Learning Media and Decimal Boards can improve elementary school students' concept mastery on decimal fractions subject matter.
