Abstract

Reasoning that is constructed from remembering is imitative reasoning, while the opposite is creative reasoning. This study aims to explore creative mathematical reasoning in solving geometric problems. Mathematical creative reasoning is reasoning that contains elements of novelty, plausibility, and mathematical foundation. This type of research is descriptive qualitative, which is explorative. The research subjects were the first-semester student in the mathematics education study program with 32 students. The results showed that from 32 students, there was only one student identified as having creative mathematical reasoning in solving geometry problems. Creative mathematical reasoning can be identified when the subject is able to reason algorithmically but is aware of problems so they cannot be resolved algorithmically so that they must form new reasoning, which consists of novelty, plausibility, and mathematical foundation. Creative mathematical reasoning arises after students make an algorithmic reasoning process, but find no solution. Novelty is the weakest indicator of creative mathematical reasoning, so it requires scaffolding to bring it up.

Abstract

This study aims to determine the feasibility of interactive learning media based on animation in learning of mathematics. This research and development consists of the initial investigation, design, construction, test, evaluation and revision, and implementation phase. This study only focused until the test, evaluation and revision phase. The results: 1) the animation-based interactive learning media expressed a very valid views of the results the average valuation of 89.05% media validator; 2) interactive learning media based on animation stated the practical results of the the average obtained from the student response sheet now reaching 87.95% gave a positive response; 3) interactive learning media based on animation effective which obtained from the percentage of the students who complete that is equal to 87.50%. Based on the results of the study, it can be concluded that interactive learning media based on animation appropriate to be used in mathematics learning in statistical material for 7th grade.
