Abstract:
This research aims to generate learning and assessment character instruments which appropriate to use in teaching junior high school Physics. This type of research is R and D,covering the development of a preliminary study, design, development, validation, and testthe practicalities with revisions as necessary, learning devices that researcher develop such assyllabi, lesson plans, worksheets, tests of learning outcomes and instrument rating characters.Research has demonstrated the validity of learning characterized by high category, while the validity of the assessment instrument is also a high category, empirical test results obtained Cronbach alpha values for character assessment instruments 0.966, larger than the table r 0.433, meaning that the instrument is reliable. Thus it can be interpreted that the learning and assessment instruments character valid and appropiate to use in junior high school physics lessons.
