The Improvement of Student Communication and Mathematical Disposition Ability Through Problem Based Learning Model at UNIMED FMIPA Students

Abstract

The active involvement of students in learning must be supported by providing special activities that are student-centered so that they can do "doing math" to find and build mathematics facilitated by lecturers. One aspect of "doing math" is to improve mathematical communication skills. The existence of communication skills will certainly bring students to a deep mathematical understanding of mathematical concepts.In addition to mathematical communication skills, an attitude that must be possessed by students is needed, including appreciating the beauty of mathematics, having high curiosity and learning mathematics. With such an attitude, students are expected to develop mathematical abilities, use mathematics to solve problems faced in their lives, and can develop mathematical dispositions.This research conducted on students of FMIPA with the aim of: (1) knowing students' mathematical communication skills taught by using problem based learning learning model and talking learning model; (2) knowing the differences in students' mathematical disposition abilities taught using Problem Based Learning model and talking learning model; (3) produce a mathematical learning device in the form of an appropriate LAS used to improve students' mathematical communication; (4) produce teaching materials in the form of textbooks with appropriate problem-based learning model used to improve students' mathematical communication
