Abstract

Rigid object equilibrium is a material that needs well rule and process aplication viewed from tranlation and rotation concept. This phenomenon related to material aplication was much found in daily life. This material instruction requires the development of Saintific Process Skills (SPS). Based on the observation result in MAN Cisewu, this material was considered difficult for the student. The teacher taught the material with mathematical formulas wihthout practicing the saintific process. One of the efforts to solve the problem by using model Context Based Learning (CBL). CBL connects content and contex. It helps the students to be more creative informing concept individually and improves the saintific process skills. Through one grup pretest-posttest design in pre experiment method, the research aims finding out the use of CBL model by using observation sheet and improving students’ saintific process skills measured by multiple choices. The result shows percentage of teacher activity 87,00% (good) and students 85,22% (good). The improvement of students’ saintific process skills showed 0,58% (medium) for N-gain means. The indicator of saintific process skills communicate of the lowest N-Gain (0,06) and the highest N-Gain (0,73) apperead on the indicator of interpretation. Hyphothetical test showed by Wilcoxon match pairs, it is found that Zcount (5,70) > Ztable (1,69). It can be concluded that Context Based Learning can improve saintific process skills of students in material rigid object equilibrium.
