The Students' Oral Mathematical Communication Skills in the Application of Peer Assessment Learning Model

摘要

Student communication ability is one of the fundamental abilities that must be had by students in doing mathematical activities. One of the ways to construct knowledge is through communication. It's through awareness during the process of expressing ideas verbally. This research was conducted with the aim of describing mathematical communication skills of Mathematics college students in a peer assessment cooperative learning models developed by Permadi [14]. The research method was descriptive qualitative by analyzing video and unstructured interview transcripts during the application of the model. The Participant was 61 students consisting of 2 classes, which were 34 students from class A and 27 students from class B who took calculus courses in the short semester of the 2018/2019 academic year. Class A was divided into 13 groups of three students and class B was divided into 9 groups of students randomly. Four group taken randomly as samples were recorded using a video camera during the application of the model. The research showed that applying peer assessment cooperative learning models promoted students' oral communication skills. The advantages are 1) getting a new mathematical vocabulary, 2) feeling free in expressing mathematical ideas logically and systematically. On the other hand, lack of student oral communication is constrained due to differences in terms of 1) experiences about content, 2) selection of mathematical vocabularies. Based on the questionnaire responses, 100% of students felt the meaning of the model in constructing knowledge about calculus, 88% of respondents said they had the opportunity to share the ideas, 88% of respondents said that it was easier to obtain learning experiences.
