Students’ gesture of naive, routine, and shopisticated behavior oriented on mathematical problem solving

摘要

Gesture aims to see students understanding when such understanding is not visible in writing. This research is a qualitative research with descriptive method that aims to examine the gesture of three students whose orientations are different in solving the problem. Based on literature, there are three kind of behavior problem solving, there are naive, routine, and sophisticated. To reveal the gesture of the students of the three behaviors, six issues related to geometry were given to two junior high school students of equal ability. Data collection was done through mathematical problem solving test, recording of student presentation and interview between researcher and student after doing the problem. Based on the result of the research, sophisticated-gesture students tended to show a profound way of thinking. Routine-gesture students were more relaxed and occasionally showed doubt and unconfidence. Naive gesture students did not tended to behave that look thoughtful. These Gestures were shown consistently for each given question.
