Abstract

Penelitian ini dilatarbelakangi dengan rendahnya kemampuan pemecahan masalah matematis siswa serta strategi pembelajaran yang masih bertumpu pada guru. Salah satu alternatifnya yakni diterapkalah strategi pembelajaran Problem Based Learning, karena strategi ini diharapakan dapat meningkatkan kemampuan pemecahan masalah matematis siswa. Penelitian ini memiliki tujuan untuk mengetahui pencapaian akhir dan peningkatan kemampuan pemecahan masalah matematis siswa yang menggunakan strategi pembelajaran Problem Based Learning lebih baik dari pada siswa yang menggunakan strategi pembelajaran Inkuiri. Metode penelitian yang digunakan adalah quasi ekperiment dengan desain non-equivalent control group. Teknik sampel menggunakan teknik purposive sampling, dimana kelas IV-A sebagai kelas ekperimen dan kelas IV-B sebagai kelas kontrol. Hasil analisis data menunjukan rata-rata skor posttest kelas ekperimen 75,03 dan kelas kontrol 68,7. Rata-rata data Gain kelas ekperimen 0,59 dan kelas kontrol 0,51. Hasil analisis tersebut memberikan kesimpulan bahwa pencapaian akhir dan peningkatan kemampuan pemecahan masalah matematis siswa kelas ekperimen lebih baik daripada kelas kontrol. The research is motivated by the low mathematical problem solving abilities of students and learning strategies that are still based on the teacher. One of the alternative is to apply the learning strategies of Problem Based Learning, because this strategy is expected to improve students' mathematical problem solving abilities. This study has a goal whether the final achievement and improvement of students' mathematical problem solving abilities using Problem Based Learning learning strategies is better than students who use Inquiry learning strategies. The research method used was a quasi experiment with a non-equivalent control group design. The sample technique used purposive sampling technique, where class IV-A as the experimental class and class IV-B as the control class. The results of data analysis showed an average posttest score of experimental class 75.03 and control class 68.7. The average Gain data of the experimental class is 0.59 and the control class is 0.51. The results of the analysis provide the conclusion that the final achievement and improvement of experimental class mathematical problem solving abilities are better than the control class.

基于学习策略的应用问题学习能力,以提高四年级学生的数学问题筛选能力
本研究在解决学生数学问题的能力和教师仍然需要的学习策略方面还不成熟。一种选择是应用基于问题的学习策略,因为这种策略有望提高学生解决数学问题的能力。本研究的目的是找出使用基于问题的学习策略的学生比使用探究式学习策略的人在解决数学问题方面取得的最终成就和能力的提高。所用的研究方法是准实验的,采用非等效控制组设计。采样技术使用有目的的采样技术,其中IV-A类为实验类,IV-B类为对照类。数据分析显示,实验班75,03和对照班68,7的平均测试后得分。平均数据增益实验类0.59,对照类0.51。分析结果表明,实验班学生的数学问题最终成绩和解决能力的提高均优于对照班。这项研究的动机是学生解决数学问题的能力低下,学习策略仍然以教师为基础。其中一种选择是应用基于问题学习的学习策略,因为这种策略有望提高学生的数学问题解决能力。本研究的目标是,使用基于问题的学习策略的学生在数学问题解决能力的最终成绩和提高方面是否优于使用探究性学习策略的同学。所用的研究方法是非等效对照组设计的准实验。抽样技术采用目的性抽样技术,其中IV-A类为实验类,IV-B类为对照类。数据分析结果显示,实验班和对照班的平均后测得分分别为75.03和68.7。实验班的平均增益数据为0.59,对照班为0.51。分析结果表明,实验班数学问题解决能力的最终成绩和提高均优于对照班。
