How is Reasoning Ability in Learning Real Analysis?

摘要

Each Mathematics Education students take Real Analysis subject must have reasoning ability. However most of them have a low reasoning ability. Reasoning ability is a drawing conclusion process by linking facts in problem solving which includes deductive thinking. The reasoning ability is able to explore their ideas and knowledge in Real Analysis subject. This research aims to describe students' reasoning ability achievement in Real Analysis subject. This research uses qualitative data. The subjects of the research are students who take the Real Analysis subject chosen by using purposive sampling. The research result reveals most of the students answer incorrectly in solving Real Analysis questions which the error is a common mistake, however the other mistakes such as misconception, careless, or just write the question are also revealed in this research.
