PENGARUH PENDEKATAN OPEN ENDED BERBASIS PRODUCTIVE STRUGGLE TERHADAP LITERASI MATEMATIS SISWA DI SEKOLAH DASAR
Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan open ended berbasis productive struggle terhadap kemampuan literasi matematis siswa sekolah dasar pada materi perkalian bilangan cacah. Penelitian ini menggunakan metode kuasi eksperimen dengan desain nonequivalent control group design. Penelitian dilaksanakan di dua sekolah dasar di Kecamatan Mangkubumi, Kota Tasikmalaya, yaitu SDN Sambongpari sebagai kelas eksperimen dan SDN Pasirjaya, Kecamatan Purbaratu, Kota Tasikmalaya sebagai kelas kontrol. Subjek penelitian terdiri dari dua kelas IV yang terdiri dari 23 kelas eksperimen dan 25 siswa kelas kontrol. Instrumen yang digunakan berupa empat soal uraian literasi matematis yang disusun berdasarkan indikator merumuskan, menggunakan, dan menafsirkan matematika. Tahapan kegiatan penelitian meliputi pemberian pretest, pelaksanaan pembelajaran selama empat pertemuan, dan diakhiri dengan pemberian posttest. Hasil analisis data menunjukkan bahwa nilai rata-rata posttest siswa di kelas eksperimen adalah 75, sedangkan kelas kontrol memperoleh rata-rata 57,28. Nilai ratarata N-Gain kelas eksperimen sebesar 53% yang berada pada kategori kurang efektif karena berada pada rentang 40-55%, sedangkan kelas kontrol sebesar 19% yang berada pada kategori tidak efektif (Rentang < 40%). Uji Wilcoxon menunjukkan 0,000 < 0,05 dengan H0 ditolak dan Ha diterima yang berarti pengaruh pendekatan open ended berbasis productive struggle terhadap kemampuan literasi matematis siswa lebih baik daripada pengaruh pendekatan konvensional yang diberikan pada kelas kontrol. Uji Mann Whitney menunjukkan nilai signifikansi sebesar 0,001 < 0,05, yang berarti kemampuan literasi matematis siswa dengan pendekatan open ended berbasis productive struggle lebih baik dibandingkan dengan penerapan pendekatan konvensional pada kelas kontrol. Uji hipotesis tersebut menunjukkan bahwa pendekatan open ended berbasis productive struggle memiliki pengaruh yang signifikan terhadap peningkatan kemampuan literasi matematis siswa. This study aims to determine the effect of an open-ended approach based on productive struggle on elementary school students' mathematical literacy skills in the multiplication of whole numbers. This study used a quasi-experimental method with a nonequivalent control group design. The study was conducted in two elementary schools in Mangkubumi District, Tasikmalaya City, namely SDN Sambongpari as the experimental class and SDN Pasirjaya, Purbaratu District, Tasikmalaya City as the control class. The research subjects consisted of two fourth grade classes consisting of 23 students in the experimental class and 25 students in the control class. The instrument used was four mathematical literacy essay questions arranged based on indicators of formulating, using, and interpreting mathematics. The stages of the research activities included administering a pretest, implementing learning for four meetings, and ending with a posttest. The results of data analysis showed that the average posttest score of students in the experimental class was 75, while the control class obtained an average of 57.28. The average N-Gain value of the experimental class was 53% which was in the less effective category because it was in the range of 40-55%, while the control class was 19% which was in the ineffective category (Range <40%). The Wilcoxon test showed 0.000 <0.05 with H0 rejected and Ha accepted which means the effect of the open-ended approach based on productive struggle on students' mathematical literacy skills is better than the effect of the conventional approach given to the control class. The Mann Whitney test showed a significance value of 0.001 <0.05, which means that students' mathematical literacy skills with the open-ended approach based on productive struggle were better than those with the application of the conventional approach in the control class. The hypothesis test shows that the open-ended approach based on productive struggle has a significant effect on improving students' mathematical literacy skills.
