Summary
Improvement and improvement of the quality of education cannot be separated from various efforts. One of the government's efforts is to implement and develop a competency-based curriculum in 2004 and 2006 into a 2013 curriculum with three domains of competence, namely: knowledge, attitudes, and skills. The implementation phase of the 2013 curriculum focuses on active student activities through a scientific process with the aim that learning will create students who have knowledge competencies, but are able to create students who are good in attitudes and skills (Istijabatun, 2008). The learning process must be changed from teacher centered to student centered, the method which was originally dominated by expository has changed to participatory and the approach which was originally more textual has turned into contextual with a balance of knowledge, skills, and attitudes. Thought, action and association and the extent to which the teacher changes the environment, presentation and teaching design (Depoter, 2007)
