This study aims to investigate whether the ability to understand mathematical concepts of students who get cooperative learning think pair square type is higher than students who get conventional learning. The research method used is a quasi-experimental method with a research design that is nonequivalent control group design. In this study sample selection using the Convenience Sampling technique is students of class VIII.5 as the control class and students of class VIII.6 as the experimental class. Experimental class students get learning using the think pair square learning model, while students in the control class get conventional learning. The instruments in this study were in the form of pretest and posttest questions in the form of questions describing the ability to understand students' mathematical concepts. In the research that has been done, the significance (sig.) 0,000 is smaller than the significance level α = 0.05. The research hypothesis testing was carried out by the Mann-Whitney test using SPSS and a significance level of 5% (α = 0.05).. In this study it was found that the ability to understand mathematical concepts of students who received think pair square learning was higher than students who obtained conventional learning.

AbstrakMasalah dalam penelitian ini adalah rendahnya Kemampuan Koneksi Matematis (KKnM) siswa dan pembelajaran terlaksana cenderung bersifat konvensional. Suatu alternatif mengoptimalkan kemampuan bermatematika siswa dan perbaikan proses pembelajaran yaitu mempertimbangkan penerapan pendekatan pembelajaran dengan pendekatan open-ended. Penelitian ini bertujuan untuk mendeskripsikan apakah terdapat interaksi Kemampuan Awal Matematika (KAM) dan gender dengan pendekatan pembelajaran dalam membelajarkan KKnM siswa. Penelitian merupakan penelitian eksperimen semu dengan rancangan Nonequivalent Control Group Design. Instrumen yang digunakan adalah essay test KKnM siswa. Populasi penelitian adalah siswa kelas VII SMP Negeri 5 Padangsidimpuan sebanyak 9 rombongan belajar dan sampel penelitian adalah siswa kelas VII-5 dan VII-6 yang masing-masing kelas berjumlah 28 siswa. Hasil penelitian melalui uji hipotesis dengan anava dua jalur menunjukkan tidak terdapat interaksi antara KAM dengan pendekatan pembelajaran dalam membelajarkan KKnM siswa dan tidak terdapat interaksi antara gender dengan pendekatan pembelajaran dalam membelajarkan KKnM siswa.Kata Kunci: Open-ended, KKnM, Pendekatan Pembelajaran, KAM, Gender. The Open-Ended Approach in Learning Mathematical Connection Ability of Middle School StudentsAbstractThe problem in this study was the low of students' Mathematical Connection Ability (MCA) and learning that tends to be conventional. An alternative to optimizing students' mathematical abilities and improving the learning process is to consider the applying of a learning approach to the open-ended approach. This study aims to describe is there any interaction between the Mathematical Prior Ability (MPA) and gender with the learning approach in teaching the students’ MCA. The research was quasi-experimental research with Nonequivalent Control Group Design. The used instrument was the students’ mathematical connection ability essay test. The population of the research was 7th-grade students of SMP Negeri 5 Padangsidimpuan with 9 groups study and the sample of the research were students of grades VII-5 and VII-6, where the number of each class was 28 students. The research results by hypothesis testing with two-way Anava showed that there was no interaction between the MPA with the learning approach in teaching the students’ MCA and there was no interaction between gender with the learning approach in teaching the student’ MCA.Keyword: Open-ended, MCA, Learning Approach, MPA, Gender.
