Abstract

This study aims to determine whether there are differences in problem solving skills of mathematics students through a resource-based learning approach with a realistic approach mathematics on the material system of linear equations two variables in class VIII SMP Swasta Muhammadiyah. The population in this study is all students of class VIII SMP Swasta Muhammadiyah 2 Medan consists of 3 classes. From 3 class, two classes were chosen in class VIII-B as experiment class I with RBL approach and class VIII-C as experiment class II with RM approach which amounted to 30 students. This research includes the kind of quasi-experimental research. The instrument used to determine students' mathematical problem solving abilities is a validated problem-solving test in the form of a description. The results showed that from the results of the research given different treatment, the average of the experimental class I with the RBL approach and the experimental class II with RM approach obtained pretest average value of 52.7 and post-test of 78.75 experimental class I while the average value of pretest experiment class II of 47.08 and post-test of 72.17. From the normality test results obtained that the two data derived from the normal distributed population with Lhitung in the experimental class I (RBL) in pretest is 0.1253 and post-test of 0.1268 and in the experimental class II (RM) on pretest is 0, 1204 and the post-test is 0.1315 because Lcount is smaller than Ltable (0.161) then both data are normally distributed. In addition, from homogeneity test results in pretest obtained Fcount is 1.3818 and at post-test obtained 1.2041 smaller than Ftable (1.858) which means that both data have the same variance. After it is known that the data of both classes are normal and homogeneous distribution, then hypothesis testing is done. From result of hypothesis test obtained tcount at pretest is 2,164 and at post-test is 2,099 bigger than ttable (1,671) which mean that H0 is rejected and Ha accepted. Thus it can be concluded that the problem-solving ability of mathematics students taught by approach of learning-based learning differs from the problem solving ability of mathematics students taught with realistic mathematics approach on SPLDV material in class VIII SMP Private Muhammadiyah 2 Medan.

Abstract

Tujuan dari penelitian ini adalah untuk melihat apakah terdapat perbedaan signifikan antara kemampuan penalaran siswa dengan menggunakan program geogebra dan kemampuan penalaran siswa tanpa menggunakan program geogebra. Penelitian eksperimen adalah salah satu penelitian kuantitatif dimana peneliti memanipulasi satu atau lebih variable bebas, mengontrol variabel lain yang relevan, dan mengamati efek dari manipulasi pada variabel terikat. Siswa dalam penelitian ini adalah siswa kelas X-IPA1 (kelas eksperimen) dan X-IPA2 (kelas kontrol) yang berjumlah masing-masing 36 siswa. Lembar tes kemampuan penalaran digunakan untuk mengumpulkan data. Tes kemampuan penalaran dilaksanakan dua kali yaitu sebelum dan sesudah pembelajaran menggunakan program geogebra yang sering disebut dengan PreTest dan PostTest. Temuan penelitian ini menunjukkan bahwa penggunaan program geogebra  berpengaruh terhadap penalaran siswa, hal ini disebabkan program geogebra mempermudah siswa membayangkan bentuk ruang dimensi tiga secara nyata, diperkuat dengan hasil nilai signifikasi lebih kecil dari nilai alpha (0,05). Selain itu, terdapat perbedaan secara signifikan antara kemampuan penalaran siswa dengan menggunakan program Geogebra dan kemampuan penalaran siswa tanpa menggunakan program Geogebra, hal ini dapat dilihat dari hasil nilai signifikansi (2 tailed) sebesar 0,001 yang berarti nilai tersebut lebih kecil dari 0,05 maka H0 ditolak dan Ha diterima. Penggunaan program geogebra berpengaruh terhadap penalaran siswa dalam materi menentukan jarak titik ke garis pada ruang dimensi tiga untuk siswa kelas X MAN 2 Tapanuli Tengah, sesuai dengan temuan penelitian. Kata Kunci : Penalaran Siswa, Program Geogebra, Ruang Dimensi Tiga  AbstractThe purpose of this study was to see whether there was a significant difference between students' reasoning abilities using the geogebra program and students' reasoning abilities without using the geogebra program. Experimental research is a quantitative research in which the researcher manipulates one or more independent variables, controls for other relevant variables, and observes the effect of the manipulation on the dependent variable. The students in this study were students of class X-IPA1 (experimental class) and X-IPA2 (control class) with a total of 36 students each. The reasoning ability test sheet was used to collect data. The reasoning ability test is carried out twice, namely before and after learning using the Geogebra program which is often called PreTest and PostTest. The findings of this study indicate that the use of the geogebra program affects students' reasoning, this is because the geogebra program makes it easier for students to imagine the shape of a three-dimensional space in real terms, reinforced by the results of a significance value smaller than the alpha value (0.05). In addition, there is a significant difference between students' reasoning abilities using the Geogebra program and students' reasoning abilities without using the Geogebra program, this can be seen from the results of a significance value (2 tailed) of 0.001 which means the value is smaller than 0.05 then H0 rejected and Ha accepted. The use of the geogebra program affects students' reasoning in determining the distance from a point to a line in three-dimensional space for class X students of MAN 2 Tapanuli Tengah, according to research findings.
