Abstract

Mathematical modeling is a bridge between mathematics and real problems that occur in students' lives. The introduction of mathematical modeling is an important agenda that must be given to high school students to optimize mathematical literacy and get used to solving problems with contextual problems. The selection of material contexts and relevant real-world problems is the initial key in teaching modeling. The selection of matrix material in the application of determining university criteria is an important consideration in introducing mathematical modeling in this study. This study used a qualitative approach involving a sample of 31 students of grade 11, MAN 1 Kota Bandung, West Java. Based on Galbraith & Holton's framework, this study evaluated the seven stages of modeling and found that students were able to understand and formulate the problem well, reaching an average score of 77.8%, but had difficulty in the interpretation and evaluation stages of the model with scores decreasing to around 60%. The use of decision-making matrices shows students' good ability to apply mathematical concepts to real-world contexts, although assistance is still needed to improve modeling skills.

Abstract

The purpose of this research is to explore the impact of using the Problem Based Learning (PBL) learning method on increasing the learning concentration of madrasah tsanawiyah students in mathematics subjects, based on their learning outcomes. This research uses a Quasi Experimental Research design with Non Equivalent Control Group Design. Experimental methods were used in this research. The study results showed that the average posttest score for the experimental class was 76.80%, while for the control class it was 81.80%. The gain index (g) for the experimental class is 0.67, while for the control class it is 0.54. The results of the t test show that tcount (4.307) > Ttable (2.014), with a significance value (2-tailed) < 0.05 (0.014), indicating that the use of the PBL method has a positive and significant effect in increasing students' learning concentration at Madrsah Tsanawiyah Miftahul Hasan Wangkal, Probolinggo, East Java, in Mathematics Learning.
