In today’s rapidly changing world, computers are a popular means of transmitting information to students. Since this is so, the microworld Super Point was developed to teach coordinate geometry to tenth-grade and older students including pre-service elementary school teachers. This microworld enables the learner to plot points, draw lines, line segments, rays and circles. In the section on points, the student learns about the four quadrants. In the line section, the student is introduced to parallel and perpendicular lines. Within the line segment section, the learner explores the concepts of midpoint and length of a line segment. The joining of two rays is shown to form a line in the section on rays. Concentric circles are taught within the circle section. The students are given an opportunity to create procedures of their own. These procedures are to identify which quadrant an inputted point lies in, to determine the slope of a given line, or to graph a line using a different equation than the microworld’s line command uses. It was found that students had a favorable attitude towards using the microworld and working on a computer. During subsequent evaluation, it appeared that the concepts taught within the Super Point microworld were acquired by the students.
