Design of Internet Integrated Students Worksheet for Developing the Ability of Mathematical Reasoning

The learning process is the availability of adequate learning resources to support student learning activities. Learning resources that are often used in lecture activities so far are textbooks of publishers that were also used in the course of Introduction to Probability. However, the use of the book is less supportive in the lecture activities. Therefore this research intends to develop student’s worksheet (LKM) which can optimally develop the ability of mathematical reasoning and can be accessed by internet. The research model used in this study was Research and development / R & D. The subjects of this study were the students of mathematics education study program. The data collection techniques used was Walk through to determine the validity of LKM highlighted on the content, constructs, and languages. The tests and interviews were also used to know the practicality of the potential effects of LKM of internet integrated toward the ability of mathematical reasoning of the students. The results of this study were 7 problems of the ability of valid and practical mathematical. In addition to a good worksheet, students can develop thinking patterns to maximize mathematical reasoning skills so that human resources with high competitiveness are created in the face of advances in science and technology.
