Abstract

Combinatoric ability allows the process of connecting several patterns and principles in formula discovery activities through generalizations to help students see the application of mathematics in real life. The model given can help in making broad rough estimates in developing their insights. The purpose of this study was to find out how combinatoric thinking skills are and whether combinatoric thinking skills contribute to mathematical statistics courses. This research belongs to the field of social sciences and can use this type of qualitative descriptive approach. The data were collected using a descriptive test which consisted of four items related to combinatoric problems. The data from the research results were processed using the SPSS program to get the contribution value of combinatoric thinking skills during the mid-test and final-test. with 23 students. The results of the analysis showed that the students' combinatoric thinking skills were quite good, where the mean and standard deviation were 71.27 and 6.09 during the middle exam and 72.00 and 5.88 at the time of the final exam. The problem that students have in combinatoric skills is the problem of mathematical modelling. The test results show that combinatoric thinking skills have a significant contribution to the mathematics-statistics course.

Abstract

Kemampuan seseorang dalam memaknai suatu konsep pengetahuan satu dengan yang lain berbeda-beda, tergantung pada kemampuannya dalam menalar. Dalam pembelajaran matematika, kemampuan penalaran merupakan salah satu kompetensi yang menjadi tujuan. Perbedaan penalaran seseorang dapat dilihat dari kemampuan siswa dalam memecahkan masalah non-rutin. Hasil observasi awal, terlihat bahwa siswa masih cenderung menyelesaikan masalah berdasarkan contoh solusi yang diberikan oleh guru, ketika diberikan masalah yang menuntut pengembangan ide, siswa mengalami kesulitan. Lemahnya siswa dalam mengembangkan ide dapat terjadi karena kurangnya pelatihan yang diberikan kepada siswa dalam mengembangkan kemampuan penalaran terhadap materi yang dipelajari. Oleh karena itu tujuan dari penelitian ini adalah untuk melihat perbedaan kedua model pembelajaran ditinjau dari kemampuan penalaran matematis siswa. Penelitian ini merupakan penelitian eksperimen dengan memberikan perlakuan yang berbeda terhadap dua kelompok sampel penelitian. Data yang dikumpulkan terdiri atas dua data, yaitu data hasil pretes kemampuan penalaran yang kemudian dijadikan dasar penggolongan siswa berupa kemampuan awal matematika serta data hasil postes kemampuan penalaran yang akan digunakan untuk melihat perbedaan kemampuan penalaran matematis siswa. Adapun analisis data yang dilakukan menggunakan ANAVA. Hasil penelitian menunjukkan bahwa terdapat perbedaan tingkat kemampuan penalaran matematis siswa tetapi tidak terdapat interaksi antara kemampuan awal matematis siswa melalui model-model kemampuan penalaran matematis siswa.
