PENGARUH MODEL PROBLEM BASED LEARNING TERHADAP KEMAMPUAN MENYELESAIKAN SOAL CERITA

Safitri Ngatiatun, Riyadi, Usada PGSD FKIP Universitas Sebelas Maret, Jalan Slamet Riyadi 449 Surakarta. e-mail: Abstract: The objective of research is to in investigate the learning model which contributes to the ability to solve the story questions better between the learning model of the problem based learning and the conventional one of the topic of discussions Least Common Multiple and Great Common Divisor of the students in grade V of state Primary Schools in kartini Cluster, Adipala sub district. This research used the experimental research method. In the learning process, the former used the learning model of Problem-Based Learning whereas the latter used the conventional one. The data of the research use test techniques. The data were then analyzed by using the t- test. Normality test using Lilliefors method, homogeneity test using Bartlett method, equilibrium test and hypothesis test using t test. Based on final data processing (post-test score) shows that the average score of the experiment group is 73,32, whereas that of the control group is 65,14. The result of the t test at the significance level of 0.05, the value of tcount = 2,536 is greater than that of ttable = 0,680, meaning that H0 is rejected, and H1 is verified. Based on the results of the research, a conclusion is drawn that the use of the Problem-Based Learning in the ability to solve the story questions on the topics of discussion of Least Common Multiple and Great Common Divisor is better than that of the conventional one. Abstrak: Tujuan penelitian ini adalah mengetahui model pembelajaran yang memberikan kemampuan menyelesaikan soal cerita yang lebih baik di antara model PBL (Problem Based Learning) atau model pembelajaran konvensional pada pokok bahasan KPK (Kelipatan Persekutuan Terkecil) dan FPB (Faktor Persekutuan Terbesar). Penelitian ini menggunakan metode penelitian eksperimen. Teknik pengambilan sampel dilakukan secara cluster random sampling. Dalam pembelajarannya, kelompok eksperimen menggunakan model pembelajaran Problem Based Learning, sedangkan kelompok kontrol menggunakan model pembelajaran konvensional. Pengumpulan data dalam penelitian menggunakan teknik tes. Uji normalitas menggunakan metode Lilliefors, uji homogenitas menggunakan metode Barlett, uji keseimbangan dan uji hipotesis dengan uji t. Berdasarkan hasil pengolahan data akhir (posttest) diperoleh nilai rata-rata kelompok eksperimen sebesar 73,32 dan rata-rata kelompok kontrol sebesar 65,14. Pada hasil uji dengan taraf signifikansi 0,05. nilai thitung (2,536) > ttabel (0,680), ini berarti H0 ditolak dan H1 diterima. Simpulan penelitian ini adalah kemampuan menyelesaikan soal cerita pada pokok bahasan KPK dan FPB dengan menggunakan model pembelajaran PBL lebih baik daripada menggunakan model pembelajaran konvensional. Kata kunci: soal cerita, problem based learning, konvensiona
