This study was aimed at describing the studentâ learning progress on decimals addition by a set of learning activitis based on Indonesian Realistic Mathematics Education. This research  method is design research which contain three stages, namely: preliminary design, design experiment and retrospective analysis. Hypothetical Learning Trajectory (HLT) has been designed to play an important role as learning design and research instrument. HLT was tested to 30 fourth grade students. The data were collected through interview, observation, and field notes. The findings of the research  showed that this instructional design could stimulate students  in the introduction of one digit decimal through the result of weight measurement, the use of the model that the students make themselves (model of) to describe the measurement results at the second level, and marking the result of the measurement to the number line and continued by describing the process of decimals addition from the measurement activity to the number line in the more formal level. Furthermore at the formal level, students are able to solve the problem of the decimals addition using the correct procedure that is the place value rule.

Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh pendekatan pemodelan matematika terhadap kemampuan koneksi matematis. Penelitian ini dilakukan di kelas VIII.A dan VIII.B MTs Aisyiyah Palembang. Metode penelitian yang digunakan adalah kuasi eksperimen dengan desain Nonequivalent Control Group Design dan teknik pengambilan sampel dengan random intact group. Instrumen yang digunakan adalah instrumen tes berupa soal kemampuan koneksi matematis. Hasil penelitian menunjukkan bahwa terdapat perbedaan peningkatan yang signifikan antara kemampuan koneksi matematis siswa yang belajar menggunakan pembelajaran pendekatan pemodelan matematika dan siswa yang belajar menggunakan pembelajaran konvensional. Hal ini terlihat dari hasil analisis uji-t menggunakan SPSS yang telah dilakukan, diperoleh t = 3,605 dengan tingkatÃ‚Â signifikansi (Sig-2-tailed) adalah 0,001. Dari hasilÃ‚Â perhitungan tersebut, signifikansi (Sig-2-tailed) yang diperoleh kurang dari taraf signifikansi = 0,05 sehingga berdasarkan kriteria pengujian maka Ã‚Â ditolak. Dari analisis data yang dilakukan dapat disimpulkan bahwa pembelajaran dengan pendekatan pemodelan matematika berpengaruh terhadap kemampuan koneksi matematis siswa.This research aimed to determine whether there is influence of mathematical modeling approach to mathematical connection ability. This research was conducted inÃ‚Â class VIII.A and VIII.B MTs Aisyiyah Palembang. The method used a quasi-experimental design with Nonequivalent control group design and random sampling technique with intact group. The instrument is used a test of mathematical connection ability. The results showed there is significant differences in improvement between mathematical connectionability of students who learn using mathematical modeling approach learning and student learning using conventional learning. This evident from the results of test analysis t test SPSS, obtained t = 3,605 with a significance level (Sig-2-tailed) was 0,001. The results of these calculations, the significance (Sig-2-tailed) were also less than the significance level of = 0.05 so that based on testing criteria then Ã‚Â was rejected. The conclusion of this research is that learning with mathematical modeling approaches affect the students' mathematical connectionability.
