Physics in Pocket: Learning Physics is Easy and Fun

Technology in the 21st century produces diverse teaching materials in support of a quality learning process. Pocket books become one of the simple teaching materials and are widely used in supporting independent learning. The addition of technology to display multi-media in a printed pocket book will improve the quality of its use. This article will describe the results of research that produces physics pocket books equipped with multi-media based on QR-Code technology. The pocket book was developed for high school physics class X material. This research and development method uses the Dick and Carey model. The feasibility of the resulting pocket book was tested material and media by experts using a valid and reliable Likertz-scale questionnaire instrument. This research succeeded in producing a product in the form of a physics pocket book equipped with media-based QR-Code technology that is feasible as a practical teaching material and can be used as a source of independent teaching material by high school students in grade X.
