Abstract

ABSTRAK Penelitian ini bertujuan untuk melihat bahwa kemampuan pemecahan masalah matematika menggunakan model pembelajaran TTW lebih tinggi daripada model pembelajaran TPS pada materi Bangun Datar di kelas VII SMP Negeri 1 Tanjung Morawa. Jenis penelitian ini adalah eksperimen semu. Populasi dalam penelitian ini adalah seluruh siswa kelas VII yang terdiri dari 7 kelas dengan jumlah keseluruhan siswa 201 orang. Pengambilan sampel dilakukan dengan cara cluster random sampling dengan mengambil 2 kelas dari 7 kelas secara acak yaitu kelas eksperimen A yang berjumlah 25 orang dan kelas eksperimen 2 yang berjumlah 26 orang. Instrumen yang digunakan untuk mengetahui kemampuan pemecahan masalah matematika siswa adalah tes kemampuan pemecahan masalah yang telah divalidasi dalam bentuk uraian. Dari hasil penelitian yang diberikan perlakuan yang berbeda, kelas eksperimen A dengan model pembelajaran TTW dan kelas eksperimen B dengan model pembelajaran TPS diperoleh nilai rata-rata kelas eksperimen A sebesar 28,20 dan nilai rata-rata kelas eksperimen B sebesar 25,27. Hasil uji t  pihak kanan dengan dk = 49 dan a = 0,05, diperoleh thitung = 3,66 dan ttabel = 1,6655 sehingga thitung > ttabel yaitu 3,66 > 1,6655 maka Ha diterima, dengan demikian  diperoleh kesimpulan bahwa kemampuan pemecahan masalah matematika menggunakan model pembelajaran TTW lebih tinggi dari model pembelajaran TPS pada materi bangun datar.Kata Kunci : Model pembelajaran Think Talk Write dan Think Pair Share, Pemecahan Masalah Matematika ABSTRACTThis study aims to see that the ability to solve mathematical problems using the TTW learning model is higher than the model of TPS learning in Building materials in Class VII SMP Negeri 1 Tanjung Morawa. This type of research is a quasi experiment. The population in this study is all students of class VII  consisting of 7 classes with total students 201 people. Sampling was done by cluster random sampling by taking 2 classes from 7 classes randomly that is experiment class A which amounted to 25 people and experiment class 2 which amounted to 26 people. The instrument used to determine students' mathematical problem solving abilities is a validated problem-solving test in the form of a description. From the result of the research given different treatment, experiment class A with TTW learning model and experiment class B with TPS learning model obtained the average value of experiment class A of 28.20 and the average value of experimental class B is 25.27. The result of right side t test with dk = 49 and  = 0,05, obtained tcount = 3,66 and ttable = 1,6655 so thitung> table that is 3,66> 1,6655 then Ha accepted, thus obtained conclusion that ability Mathematical problem solving using TTW learning model is higher than the model of TPS learning in flat matter.Keywords: Think Talk Write and Think Pair Share Learning Model, Mathematical Problem Solving

Abstract

AbstractThe aim of this research is to study if pupils’ mathematical problem solving ability in the classroom that taught using Problem Based Learning (PBL) higher than in the classroom that  taught using Project Based Learning (PjBL). The population of this research is all pupils in class VII SMP Negeri 2 Panai Tengah. The sample of this research consists of twoclasses, namely, VII – 1 as the experiment class taught using PBL (30 pupils), VII – 2 as the comparison class taught using PjBL (31 pupils). The design of this research is posttestonly comparison group. The result of the research shows that the mean score are 54.07in experiment class and 41.32 in the comparison class; and tcalculation ≤ t­table­, that is,1.327 ≤ 1.671 with significance level of 0.05 one tailed. It means that the pupils’ mathematical problem solving ability in the classroom taught using PBL model is not higher than in the class taught using PjBLmodel.Keywords: Mathematical Problem Solving Ability, Problem Based Learning, Project Based Learning
