Development of problem-based student worksheet with authentic assessment to improve student's physics problem solving ability

Abstract

Student problem solving abilities have not fully developed. Student motivation and activity has not been seen to increase in learning activities. One is the unavailability of teaching materials that allow students to grow and develop. This study aims to develop Student Worksheets based on valid authentic issues, practical, and effective. This type of research is development research. audits of the Revees model (2006), Mc Kenney (2001), Nieveen, et al. (2006) and Plomp (2013). In the early stages of the study is to perform needs analysis, learner analysis, curriculum analysis, concept analysis, and analysis of existing teaching materials. In the prototype phase, validity and practicality are carried out formative evaluations that include self-evaluation, and one-to-one. At the evaluation stage, a brief evaluation is conducted to determine the effectiveness of the product. However currently discussed at the beginning of preliminary research there is only preliminary research. From this research will be produced learning support devices based on problems with authentic assessment. These models and support systems meet the valid and practical criteria and are worthy of use.
