Abstract

Penelitian ini bertujuan untuk menguji keekfetivan model pembelajaran blended-learning terhadap kemampuan pemecahan masalah matematika. Penelitian ini merupakan penelitian kuantitaf eksperimen one group pretest-posttest design dengan lokasi penelitian di SMPN 16 Kab. Sorong. Teknik pengumpulan data menggunakan teknik tes dengan isntrumen soal uraina, dan teknik Observasi dengan instrument Lembar Observasi Keterlaksanaan Pembelajaran. Selanjutnya data dianalisis menggunakan uji normalitas, uji paired sample t-test dan Uji N – gain score. Hasil penelitian bahwa nilai rata – rata post – test sebesar 3,055 dan pre – test sebesar 3,198. Dengan demikian nilai post – test > pre – test. Berdasarkan kualifikasi kemapuan pemecahan masalah matematika, maka tingkat kemampuan pemecahan masalah peserta didik tergolong rendah karena mean 24,83 < 54,99. Selanjutnya hasiln N-gain score adalah 0,14 dan niliai minimumnya adalah 0,03. Sedangkan nilai maximum dari n – gain persen adalah 14,29 dan nilai minimumnya adalah 2,50. Selain itu diketahui juga bahwa nilai rata – rata N – gain score adalah sebesar 0,0824 yang masuk dalam kategori rendah karena nilai g < 0,3 dan N- gain persen sebesar 8,2442 atau 8,24% yang masuk pada kategori tafsiran tidak efektif karena nilai persentase yang dihasilkan < 40%. Dari hasil uji hipotesis dapat disimpulkan bahwa model pembelajaran blended – learning tidak efektif terhadap kemapuan pemecahan masalah matematika pada peserta didik kelas VII di SMPN 16 Kab. Sorong.

Abstract

The purpose of this study is to see the influence of the role playing method on student learning outcomes. The research used is qualitative research with the type of experimental research with Pre-Exsperimental Design. The sample in this study is grade IV students of SD Inpres 48 Sorong Regency which totals 23 students. This study uses posttest and pretest test techniques. The data results obtained used the results of statistical descriptions of pretest and posttest. From the data analysis, the Shapiro wilk normality test was obtained, which was 0.231 for the pretest and 0.253 for the posttest. If the significant value > 0.05, the data is declared to be normally distributed. The results of the N-Gain test data showed that the percentage of the mean value of the N-Gain score was 0.539 and the value was in the range of 0.30<N-Gain<0.70, included in the medium value criteria. The results of the data of one t-test sample showed that the T value was 87,241 with df which was 22. From this explanation, the p-value is 0.001 < a(0.05), then HO is rejected and H1 is accepted. Thus, it can be concluded that there is an influence of the role playing method on student learning outcomes.
