Learning device merupkan important factor in the learning process and directing students to acquire learning experience. The purpose of this study to produce a device-oriented high school physics learning Contextual Teaching and Learning (CTL) are valid, practical and effective. This type of research is the development of research (research and development) using the model proposed by Plomp (2010) which consists of the initial investigation phase (preliminary research), phases of design, realization (prototyping phase) and phase assessment (assessment phase). The research results are to be obtained that the learning device-oriented high school Contextual Teaching and Learning (CTL) that includes lesson plans, Hand outs, and the Student Activity Sheet are in the category of very valid. Value practicality based on the observation sheets and questionnaires practicality of the draft by the teacher at the high school Adabiah 2 Padang practical categorized can be seen from the results of cognitive learning with an average of 88 and psychomotor in SMA Adabiah 2 Padang with an average of 90. The results of the analysis of student activity observation shows that developed an effective learning tool. This research resulted in device physics learningoriented approach Contextual Teaching and Learning (CTL) on the material temperature and heat of class X SMA Adabiah 2 Padang extremely valid and practice.
