ABSTRAK

The purposes of this research are (1) to create teaching material of tangent to a circle with specific approach in the form of students’ activity sheet which is valid, practical and potential effect as well as explaining its process of development. In developing teaching material, the researcher applies through preliminary and prototyping steps with formative evaluation. There are 39 students of SMPN 9 Palembang involved in prototyping steps. The technique of data collection used is documentation, walk trough, observation sheet, and the test result. This research will result in teaching material of tangent to a circle with scientific approach in the form of students’ activity sheet which is valid, practical, and potential effect. The validity of teaching material is viewed from the result of expert validity in the expert review steps and prototype test is in the small group step. On the other hand, practicability of teaching material is gained from the revision result test one-to-one and small group. The potential effect of this teaching material is known from the result of field test and the final evaluation of student test result. The final test result shows score category 48.15% (very good), 33.33% (good), 11.11% (moderate), and 7.41% (poor). From observation done, it is gained the percentage of students activity is above 75% which is categorized ‘very good’ and ‘good’. The analysis result also shows the difficulty of students in learning activity, especially in negotiation activity.
