Pengembangan Soal Matematika Berkarakteristik TIMSS Tipe Pemecahan Masalah pada Topik Geometri Pengukuran Volume Kubus dan Balok Kelas VIII

This research aims to produce a TIMSS characterized math problems that are valid and reliable. The method of this research is Design Research. The sample of this study were 31 students of SMP Negeri 1 Inderalaya. The procedure of this study through the stages of Preliminary Evaluation and Formative Evaluation. Based on the results obtained 7 of TIMSS characterized with characteristics (1) using real-life contexts, (2) using characteristics of TIMSS, and (3) the type of problem-solving that problem logically and empirically validxa0 and reliable. Valid logically be fulfilled from the results of the assessment validator, where the validator comment on the terms of the content, construct, andxa0 language. Valid empirically criteria for both internally for items validity and externally for the whole items validity. Items also expressed reliable with a high level of confidence as the test instrument through items with the analysis result reliability coefficient of 0,703.

IMPROVING INTUITION SKILLS WITH REALISTIC MATHEMATICS EDUCATION

The intention of the present study was to see the improvement of students’ intuitive skills. This improvement was seen by comparing the Realistic Mathematics Education (RME)-based instruction with the conventional mathematics instruction. The subject of this study was 164 fifth graders of elementary school in Palembang. The design of this study was a Pretest-Posttest Control Group Experiment. Data was analyzed with the help of SPSS. The result of this study showed that there was different improvement of students’ skills. The improvement was higher in the class using the RME-based instruction that in conventional mathematics class.
