Tujuan Â penelitian Â ini adalahÂ  untuk mengetahui Â keefektifan pembelajaran matematika Â dengan Â Model Â Knisley Â dan Â mendeskripsikan Â kemampuan komunikasi Â matematis Â siswa berdasarkan Â self Â efficacy. Jenis penelitianÂ  ini adalah penelitianÂ  mixed methods denganÂ  explanatory sequential design. Populasinya adalah siswa Â kelasÂ  VII SMP Â N Â 13 Magelang. Â Pengambilan sampel Â dilakukan Â dengan teknik random sampling, diperolehÂ  kelas VII B sebagai kelas eksperimenÂ  dan kelas VII A sebagai Â kelas kontrol. Â Subjek penelitian Â 2 siswa self Â efficacy Â tinggi dan Â 2 siswa self Â efficacy rendah. Pengumpulan data meliputiÂ  skala, tes, dan wawancara. Data Â dianalisis Â dengan uji proporsi, Â uji perbedaan Â rata-rata, Â uji bedaÂ  rata-rata berpasangan, dan deskriptif Â kualitatif. Â Hasil penelitian Â menunjukkan bahwa Â (1) proporsi kemampuan komunikasi Â matematis Â siswa Â kelasÂ  eksperimen Â mencapai ketuntasan Â belajar klasikal 75%, (2) rata-rataÂ  kemampuan komunikasi matematis siswaÂ  Â kelasÂ Â  eksperimenÂ  Â lebihÂ  Â baikÂ  Â dariÂ  Â rata-rata kemampuan Â komunikasi matematis Â siswa Â kelasÂ  kontrol, Â (3) terdapat peningkatan rata-rata Â kemampuan komunikasi Â matematis Â siswa kelas eksperimen dalam kategori tinggi yaitu sebesar 0,72, Â (4) siswa Â dengan Â self efficacy Â tinggiÂ  memenuhi empat Â aspek Â kemampuan komunikasi Â matematis, danÂ  (5) siswa dengan Â self Â efficacy Â rendah Â memenuhi tiga aspek kemampuan komunikasi Â matematis.The Â purpose of this research was to determine Â the effectiveness of mathematics Â learning using Knisley's Models and describe students' mathematical communication skills based on self Â efficacy. Â The method Â used in this Â research is Â a mixed Â methods with explanatory sequential design. The populationÂ  is the seventhÂ­grade students of SMP N 13 Magelang. Sampling was conducted by random sampling Â technique, Â is obtained as an experimental class in seventhÂ  grade B and the seventh grade A as a control class. The subject of this research is 2 high self efficacy students Â and 2 low self efficacy students. The data collection includes Â scale, tests and interviews. Data were analyzedÂ  by proportion test, the average differenceÂ  test, Â different Â average Â in pairs Â test, and a descriptive qualitative. Â The results showed Â that Â (1) the Â proportion of student's Â mathematical Â communication Â skills Â in experimentalÂ  Â class can reach Â 75% classicalÂ  completeness, Â (2) the Â average of Â student's mathematical communication skils experimental Â class is better than the average of student's mathematical communication skils control class, (3) there is an average increase in students' mathematical communication skills experimental Â class in high category amounts 0,72, (4) students with high self efficacy meet Â four aspects of mathematical communication skills, and (5) students with low self efficacy meet three aspects of mathematical communication skills.
