<![CDATA[Abstract: Powerpoint assisted problem posing versus STAD model: A comparison study in improving mathematical connection ability. Objectives: The purpose of this study were to determine the differences and the effectivity between Powerpoint Assisted Problem Posing and Student Team Achievement Divisions (STAD) on mathematical connection ability. Methods: The population of this study were 289 students of SMPN 1 Talang year of 2017/2018 class VII semester II. Data of mathematical connection ability were collected by using documentation, tests and observations. Results: There were significant differences in mathematical connection ability between Powerpoint Assisted Problem Posing and the STAD model (tcalc=5.287 ttable=1.960). Conclusions: Powerpoint Assisted Problem Posing Model is more effective than STAD model (tcalc=5.287 ttable=1.645 and sig. 0.000) in improving mathematical connection ability.Keyword: Powerpoint-assisted problem posing, STAD model, mathematical connection ability. Abstrak: Model problem posing berbantuan powerpoint dan model STAD: Studi perbandingan dalam meningkatkan keterampilan koneksi matematis. Tujuan: Mengetahui perbedaan dan efektivitas antara model Powerpoint berbantuan Problem Posing dan model pembelajaran STAD terhadap kemampuan koneksi matematis. Metode: Populasi penelitian ini adalah 289 peserta didik kelas VII semester II SMP Negeri 1 Talang tahun ajaran 2017/2018. Temuan: Terdapat perbedaan kemampuan koneksi matematis yang diajar menggunakan model pembelajaran Problem Posing berbantuan Powerpoint dengan model pembelajaran STAD (tcalc=5.287ttable=1.960). Kesimpulan: Model pembelajaran Problem Posing berbantuan Powerpoint lebih efektif dibandingkan model pembelajaran STAD dalam meningkatkan kemampuan koneksi matematis.Kata Kunci: Model problem posing berbantuan powerpoint, model STAD, keterampilan koneksi matematis.
