Abstract

ABSTRACT: The mathematical communication is the basic ability which must be possessed by mathematics practitioners and users during teaching-learning process and assessing mathematics. By using Jigsaw technique as a part of cooperative learning, this technique considers students to work interdependently in a group of four to six but at the same time have individual responsibility. Every group is responsible for the mastery of the learning material. The aim of this research, however, was to examine the quality of mathematical communication ability between students who were treated with cooperative learning model and those with conventional model. The population of this study were second grade students of SMUN Banyumas in the academic year 2005/2006. Two classes were taken as sample, each of them had thirty students. Data were collected by means of communication ability test that had satistactory face and content validity and had reliability of 0.5335 (high reliability). Based on analisys result using t-test, it was concluded that the cooperative learning model gave better result to the students communication ability than the conventional one.KEY WORDS: jigsaw, cooperative learning model, conventional learning model, mathematical communication ability.  About the Authors: Drs.

Abstract

ABSTRACT: The development of science and technology stimulates the rise of effort to make use of all facilities in all fields. One of the results is increasing number of computer use in Indonesia. This condition encourages educational practitioners to develop several models of learning media by using computers with purposes of tutorial, exercises, simulations, and games. Meanwhile, learning process which applies some media of simulation provides some benefits as they are realistic, secure, and simple. This simulation will lead students into a visualization of real life condition. Without media, students will usually imagine what they learn. It later exposes them with some problems that influence their abstractions. If a lecturer only explains about Transformation Geometry without using simulation, there is a big opportunity that students will yield misconception or they will only remember it with little understanding. This research aims to develop a valid and practical the Transformation Geometry simulation. The method in this research is a design research from a technology perspective that uses a preliminary stage and evaluation stage. The result presented the simulation of the definition of reflection, rotation, rotation half-round, and translations that have been made are in accordance with the curriculum and the existing concepts. Try-out result shows that the simulation can help students find their own concepts of reflection, rotation, rotation half-round, and translation; and sets up students to communicate. The conclusion of this research is that the result of simulation design that has been created has to be valid and practical.KEY WORDS: Development of Science and Technology; Computer Use; Transformation Geometry; Learning Process; Understanding of Concepts.  About the Authors: Ahmad and Anton Jaelani are the Lecturers at the Department of Mathematics Education, Faculty of Education and Teacher Training UMP (Muhammadiyah University of Purwokerto), Jalan Raya Dukuhwaluh, Purwokerto, Central Java, Indonesia.
