摘要：Penelitian ini bertujuan untuk mengetahui (1) ketuntasan belajar peserta didik yang diajar dengan model experiential learning dengan strategi REACT,(2) rata-rata kemampuan komunikasi matematis peserta didik yang diajar dengan model experiential learning dengan strategi REACT. Populasi penelitian ini adalah semua peserta didik kelas VII SMPN 6 Purworejo tahun pelajaran 2012/2013. Sampel diambil dengan teknik cluster random sampling. Terpilih kelas VIID sebagai kelas kontrol dan kelas VIIE sebagai kelas eksperimen. Data hasil penelitian dianalisis dengan uji proporsi dan uji t. Pada uji proporsi kelas kontrol diperoleh zhitung(-1,633) < ztabel(1,64) dan kelas eksperimen diperoleh zhitung(2,042) > ztabel(1,64). Pada uji t diperoleh thitung(3,396) > ttabel(1,667). Berdasarkan hasil penelitian dan pembahasan disimpulkan (1) peserta didik yang diajar dengan model experiential learning dengan strategi REACT sudah mencapai kriteria ketuntasan minimal,(2) rata-rata kemampuan komunikasi matematis peserta didik yang diajar dengan model experiential learning dengan strategi REACT lebih baik dibanding yang diajar dengan model ekspositori.
其他摘要：The purposes of this research were examining (1) whether students by using experiential learning with REACT strategy were able to achieve mastery of learning or not,(2) the average of students’ mathematics communication ability by using experiential learning with REACT. The population in this research was all of the seventh graders student of SMPN 6 Purworejo in the academic year 2012/2013. The sampling technique which was used in this research was cluster random sampling. VIID was chosen as control class and the class experimental was VIIE. Data of the research is analyzed by using proportion test and independent samples T test. The result of proportion test in control and experimental class was z (1,633) < ztable (1,64) and z (2,042) > ztable (1,64). The result of independent samples Ttest was t (3,396) > ttable (1,667). Based on the result,it could be concluded that (1) the students by using experiential learning with REACT strategy was able to achieve the mastery of learning,(2) the average of students’ mathematics communication ability by using experiential learning with REACT strategy was better than expository learning.
