<![CDATA[This quasi experimental research aimed to find out the influence of cooperative learning model types think pair share towards learner’s mathematical concept comprehension. The population of this research was learners of grade VIII of Junior High School of Tri Sukses Natar in academic year of 2018/2019 as much as 85 learners that were distributed into four classes, that are VIII A until VIII D. The sampling was done by cluster random sampling technique and it was chosen learners of VIII C and VIII D as samples. The design which was used in this research was the non equivalent control group design. Research data were obtained through test of mathematical concept comprehension. The data analysis which was used was . The result of this research show that mathematical concept comprehension of learner who follow learning with cooperative learning model types TPS higher than mathematical concept comprehension of learner who follow learning with non-TPS model. Based on the results and dicussion, the conclusion of the research is the cooperative learning model types TPS model was influence to learner’s mathematical concept comprehension. Penelitian eksperimen semu ini bertujuan untuk mengkaji pengaruh model kooperatif tipe think pair share (TPS) terhadap pemahaman konsep matematis peserta didik. Populasi pada penelitian ini adalah peserta didik kelas VIII SMP Tri Sukses Natar tahun pelajaran 2018/2019 sebanyak 85 peserta didik yang terdistribusi dalam empat kelas, mulai dari VIII A hingga VIII D. Pengambilan sampel dilakukan dengan teknik cluster random sampling dan terpilih peserta didik pada kelas VIII C dan VIII D sebagai sampel. Desain penelitian ini menggunakan non equivalent control group design. Data penelitian diperoleh menggunakan instrumen tes pemahaman konsep matematis. Pengujian hipotesis menggunakan uji . Hasil dari penelitian ini menunjukkan bahwa pemahaman konsep matematis peserta didik yang mengikuti pembelajaran dengan model kooperatif tipe TPS lebih tinggi dari pemahaman konsep matematis peserta didik yang mengikuti pembelajaran dengan model pembelajaran non-TPS. Berdasarkan hasil dan pembahasan, diperoleh simpulan bahwa model kooperatif tipe TPS berpengaruh terhadap pemahaman konsep matematis peserta didik.Kata kunci: model kooperatif, pemahaman konsep, think pair share]]>
