Abstract
Technological developments will affect the world of education in terms of institutions, materials, teachers, methods, infrastructure and so on. This is a challenge that must be answered by the world of education, in the 2013 Curriculum where learning is required to be able to balance three student competencies including attitude, skills and knowledge competencies. To support the learning process, teaching materials in the form of e-modules are needed. This research aims to produce a product in the form of a physics e-module on global warming material for class XI high school. This research is included in research and development research with the Plomp development research model. Preliminary research data was obtained from needs analysis through interviews with teachers and distribution of questionnaires to high school students in the city of Padang and legitimacy information was gotten from 5 material science instructors. The instruments in this exploration were educator interview sheets, self-assessment sheets and master legitimacy sheets. Data were analyzed descriptively. This research produces a physics e-module with a contextual teaching and learning model with REACT learning strategies on global warming material. The self-evaluation results show that the e-module is in the good category. The validity test results obtained an average value of 0.81 which is in the valid category. Based on this data, the physics e-module with the contextual teaching and learning model with the REACT learning strategy has met the requirements in terms of validity so that it can be used in schools.
