This research consists of three stages, namely Self Evaluation, Prototyping, and Field Test. The initial step of the research is to use various sources in the field and literature review. Product design is done by preparing student worksheets and student character observation sheets. Products that have been designed are then developed by means of judgment, trials and revisions. From the results of the development then a student worksheets hypothetical product is obtained and will be tested for its effectiveness. Effectiveness testing is carried out in the use of trial activities through the implementation of student worksheets hypothetical product.
