Abstract

This study aims to analyze the learning process of introverted students on algebraic operating materials and determine the results of treatment with Problem Based Learning on students' mathematical reasoning abilities. This type of research is an experiment with a single subject or Single Subject Research. The design used is A-B. Data collection techniques through observation, tests, interviews, and documentation. Data analysis uses analysis in conditions and analysis between conditions. Based on the results of the study, the introverted student learning process on algebraic operating material is the subject preparing needs, making designs, identifying, finding and delivering solutions, and conducting evaluations. While the treatment results in the form of Problem Based Learning showed a significant increase, the mean level of test results increased from 48.75 to 92.75 and the percentage of overlap was 0. It was concluded that the use of PBL models had a positive influence on the mathematical reasoning ability of introverted students. It is hoped that the Problem Based Learning model can be used as an alternative learning model to improve the mathematical reasoning ability of introverted students and learning when at school.

Abstract

The purpose of this study was to find out that Think Pair Share with mathematical comics is more effective than Think Pair Share learning without using comics. The research method used is an experiment with the design of Post-test-Only Control Design. The sample size was 64 students taken using cluster random sampling technique. The instrument used in this study is the Mathematical Problem Solving Test. Data analysis techniques were used using the Wilcoxon Signed Rank Test non-parametric statistical test. The results of the study showed that the learning of Think Pair Share models by using mathematical comics was no more effective than learning Think Pair Share without using comics. Although this study shows the opposite results from existing theoretical studies, in general, the use of learning media such as mathematical comics collaborated with any model can make mathematics learning more effective.

Abstract

Mental retardation is a condition of someone who has intellectual skills below average. For this reason, the learning process for mentally disabled students requires a different strategy when compared to learning for regular students. Mathematics has the characteristics of an abstract concept. Learning requires media so that the message conveyed by the teacher to students can be adequately achieved. For this reason, learning mathematics requires media such as pictures. In this regard, the purpose of this study was to determine the increase in the creativity of mentally disabled students in solving mathematical problems using media images. This study used one subject with mental retardation characteristics selected by purposive sampling. This single-subject research uses an ABA design. The instrument used in this study was a mathematical creativity test given to subjects in each session. Data analysis techniques use visual techniques, including analysis within and between conditions. The results showed that the subjects were in stable condition at the first baseline, with an average of 66.63. The issues were stable at the intervention, with an average of 79.18. in the retrieval or the second baseline phase, the subjects were in an unstable situation with an average of 62.72. Apart from that, in between conditions, it was found that between the first conditions had increased. Between the second condition, it decreased because media images were not used in learning mathematics. These results indicate that using media images can improve the creative mathematical abilities of mentally disabled students.
