ABSTRACT

Material and time angle measurements are generally difficult for some students because it is abstract. While students more easil y learn from something that is concrete. Therefore, in designing learning angle measurements made learning media. The method of research used is the design research is consisting of three stages: preliminary design, design of experiment, and retrospective analysis. This study develops instructional media used on the subject of measurement of the angle and time through a series of activities, procedures, and strategies for students in the training of creative thinking ability mathematically. The results of t his research are mathematics learning media in the form of mechano clock and learning trajectory for each activity, consist of three activities. First activity, students were able to measure kinds of angle with mechano. Second activity, the students were a ble to recognize the kinds of angles with hand shape game. Third activity, students were able to understand the relationship between measurement angle and time with mechano clock. Overall activity aimed to develop students' mathematical ability of creative thinking in solving various problems associated with the subject and time of angle measurement.
