<p><strong>Abstract: </strong>The aim of this research was to reveal the effect of TGT cooperative learning model with talking chips technique, TGT cooperative learning model, and direct learning model to the mathematics achievement in polyhedron subject viewed from mathematics communication ability. The type of this research was a quasi-experimental by 3x3 factorial design. The population was the eighth grade of Junior High School students at Wonogiri regency on academic year 2013/2014. The sample was taken by using stratified cluster random sampling technique. The instruments used for collecting data were mathematics achievement test and mathematics communication ability test. Analysis of the data used was unbalanced two-way analysis of variance. The conclusion of this research shows that TGT cooperative learning model with talking chips technique gives the same achievement as TGT cooperative learning model, but gives better achievement than direct instruction model, and TGT cooperative learning model gives better achievement than direct instruction model. It shows the same result in each categories of mathematics communication ability. Another conclusion shows that students with high mathematics communication ability have the same achievement as students with middle mathematics communication ability but they have better achievement than students with low mathematics communication ability, and students with middle mathematics communication ability have better achievement than students with low mathematics communication ability. It shows the same result in each learning model.<strong></strong></p><strong>Key words</strong>: TGT, Talking Chips, and mathematics communication ability

Penelitian ini bertujuan untuk mengetahui penerapan model pembelajaran  discovery learning terhadap hasil belajar matematika ditinjau dari minat belajar siswa. Metode penelitian ini merupakan penelitian eksperimen semu dengan desain 2x2 faktorial. Tempat penelitian dilakukan di SMP Negeri di Kota Rantepao, tahun pelajaran 2014/2015. Populasi penelitian adalah semua siswa kelas tujuh SMP Negeri Rantepao dan sampel diperoleh dengan menggunakan teknik cluster random sampling dengan jumlah anggota sampel sebanyak 78 siswa.  Model pembelajaran sebagai variabel bebas, minat belajar sebagai variabel intervening, dan hasil belajar matematika siswa sebagai variabel respon. Model pembelajaran discovery learning digunakan pada kelompok perlakuan, dan model pembelajaran langsung digunakan pada kelompok pembanding. Data dikumpulkan dengan menggunakan instrumen tes hasil belajar matematika dan skala minat belajar dan digunakan ANAVA dua jalan. Hasil penelitian menunjukkan bahwa: (1) model pembelajaran dan minat belajar mempunyai pengaruh terhadap hasil belajar matematika siswa, dan (2) model pembelajaran discovery learning lebih baik daripada model pembelajaran langsung. Kata kunci: model discovery learning, model langsung, minat belajar, hasil belajar matematika siswa. ABSTRACT The major objective of this research was to investigate the effects of applying discovery learning on mathematics achievement in terms of student's learning interest. The research methodology was a quasi-experimental and the design of the research was a 2x2 factorial. The research was conducted in SMP Negeri in Rantepao City in academic year 2014/2015. The population of research was made up of all seventh grade students of SMP Negeri Rantepao from where a sample of 78 students was obtained by using cluster random sampling technique. Learning model as the independent variable, student's learning interest as intervening variable, and mathematics achievement of student as response variable. The treatment class group taught by using Discovery learning model. While the comparison group was taught by Direct Instruction. The data were collected using the mathematics learning test instrument and learning interest scale. The data collected were analyzed with two way ANOVA. The findings showed that: (1) learning model and interest in learning have an effect on student learning outcomes, and (2) Discovery learning model is better than Direct Instruction. Keywords: discovery learning model, direct instruction, student interest, matemathics acievement.

<p>Tujuan penelitian ini untuk mengetahui keefektivan pembelajaran <em>Team Accelerated Instruction</em> terhadap kemampuan pemecahan dan prestasi belajar matematika siswa. Jenis Penelitian ini adalah eksperimen semu. Populasi dalam penelitian ini adalah seluruh siswa SMP kelas VIII se-kota Jogjakarta dengan ukuran sampel 369 siswa yang diambil dengan menggunakan teknik <em>cluster random sampling</em>. Variabel penelitian adalah kemampuan memecahkan masalah, prestasi belajar matematika dan model pembelajaran. Data diperoleh dengan tes untuk menentukan kemampuan awal siswa, kemampuan memecahkan masalah dan prestasi belajar yang kemudian diuji dengan analisis variansi multivariat<em> </em>(MANOVA). Hasil penelitian menunjukkan bahwa model pembelajaran <em>Team Accelerated Instruction</em> lebih efektif digunakan jika dibandingkan dengan model pembelajaran langsung.</p><p><em>The purpose of this research was to determine the effectiveness of teams Accelerated Instruction to the problem solving and mathematics achievement. This research kind was the quasi experiment. The population in this research was all the VIII class student of more than Jogjakarta with the sample totally 369 students was taken with cluster random sampling. Variably the research was the problem solving, mathematics achievement and learning models.  Data obtained by test methods for the stage of student, problem solving, and </em><em>achievement are then analyzed to the </em><em>multivariate analisis of variance (</em><em>MANOVA). The results of this research are team accelerated instruction more effectiveness with direct instruction</em></p>
