Abstract

Tujuan penelitian ini adalah untuk mengidentifikasi jenis dan faktor penyebab kesulitan mahasiswa dalam memecahkan masalah matematika berbasis open ended materi nilai mutlak berbentuk persamaan dan pertidaksamaan, serta memberikan saran untuk dosen. Subjek penelitian terdiri dari 138 mahasiswa PGSD UMSIDA pada matakuliah konsep dasar matematika tahun ajaran 2016-2017. Metode penelitian yang digunakan adalah kualitatif deskriptif. Instrumen penelitian terdiri dari Lembar Tes Pengetahun Nilai Mutlak dan pedoman wawancara. Berdasarkan data, jenis-jenis kesulitan mahasiswa meliputi tidak dapat sepenuhnya mengaplikasikan konsep jarak dan definisi nilai mutlak sehingga langkah penyelesaian tidak tuntas; mengalami misunderstanding syarat nilai mutlak; mengalami miskonsepsi berupa anggapan nilai mutlak selalu bernilai positif; mengalami kesulitan dalam hal konseptual, prosedural, dan algoritma. Faktor-faktor penyebab kesulitan diantaranya mahasiswa menghafal rumus dan teorema tanpa memahami konsep dasar jarak dan definisi nilai mutlak; mahasiswa terbiasa menggunakan rumus cepat sebagai bekal untuk masuk perguruan tinggi. Saran penelitian yakni dosen yang akan mengajarkan nilai mutlak harus menanamkan pentingnya konsep dasar dan melakukan pembiasaan pembelajaran konstruktivistik.

Abstract

Cooperative learning is the type of Teams Games Tournament (TGT) which is a learning model in which there are stages such as games which can make the students communicate mathematically, more creative, have a positive attitude towards mathematics, and appropriate in solving mathematical problems. But in fact, communication skills and problem solving that should be owned by the students as a result of the learning process of mathematics meet the minimum completeness criteria (KKM). This study aims to describe the effectiveness of Cooperative learning of TGT type at mathematics learning in terms of communication skills and problem solving in class VIII SMP N 1 Seyegan the school year 2016/2017.  This research is a quasi ekspreriment research with pre-posttest nonequivalent control group design. This study uses two groups: the experimental group and the control group. The population study includes all students of class VIII which consists of four classes. From the existing population, it is drawn randomly two classes, namely VIII A and VIII C as samples. Mathematics Learning in class VIII A (experimental group) uses TGT type Cooperative learning and mathematics learning in class VIII C (control group) uses direct instruction. The instrument of this study is testing the communication and problem solving capability. To test the effectiveness of the study, it is used the analysis of one sample t-test. Whereas the T2 test hotteling is foolowed by univariate t-test which is used to determine more effective model. The result of research indicates that: (1) Cooperative learning of TGT-type and direct instruction in mathematics is effective in terms of communication skills and problem-solving; and (2) Cooperative learning of TGT type is more effective than direct instruction type in term of communication skill in class VIII SMPN 1 Seyegan. Keywords: TGT, mathematical communication, problem solving

Abstract

The purpose of this research is to describe: (1) the achievement and the interest in mathematics learning of the students taught using the CTL method and that of those taught using the Open-Ended method in the material on probability, (2) the effect of students’ mathematics learning styles on their achievement of mathematics on probability material, (3) the effect of students’ mathematics learning styles on their learning interest in mathematics on probability material, (4) the effect of teaching method and  students’ mathematics learning styles on their achievement and interest in learning mathematics on the probability material. This research used a quasi-experimental research design by two experimental groups. The analysis of the data used normality and homogeneity testing, the multivariate analysis, and the post-hoc test involving the Bonferroni procedure.The results of the research are as follows: (1) In the probability material, the group of students taught by the CTL method has better achievement and mathematics learning interest than that of those who are taught using the Open-Ended learning method. (2) There is an learning style effect (auditory, visual, and kinesthetic) on their achievement of mathematics in the probability material.(3) There is an effect of learning style (auditory, visual, and kinesthetic) on their learning interest in mathematics probability material. (4) There is no effect of teaching method and students’ mathematics learning styles on their  achievement and learning interest in mathematics in the probability material. Keywords: CTL, Open-Ended, learning styles, achievement, learning interest
