Mathematics Learning Device Development Based On Constructivism Approach To Improve Mathematical Reasoning Skill Of Class X Students In Vocational High School (SMK)

摘要

The purpose of mathematics learning is to have the students think logically in order to allow them to achieve knowledge. Logical thinking may help the students to conclude the knowledge. In order to do so, students should possess reasoning skill. Constructivism approach can actually trigger students? mathematical reasoning skill in the learning process. This is due to the constructivism itself is enabling the students to build or to explore their own knowledge. Moreover, the students also provided with opportunity to take initiative in comprehending their knowledge as to facilitate them in learning, so that they would have an optimal opportunity to allow them to train to develop their competence. Among the developed reasoning skill indicators are performing mathematics manipulation, arranging or providing evidence toward solution validity, and drawing conclusion as well as assuring the validity of an argument. The development model employed is plomp model, which consists of three stages; first, preliminary research stage; second, development or prototyping stage; and third, the assessment stage.
