Abstract
This research purposes to represent the validity, effectiveness and practicality of student worksheets according to the realistic mathematics learning approach and to build students' self-efficacy and potential for solving mathematical problems. The Tessmer model is employed in the research development model. The topics covered in this research were eighth grade students of SMP Gajah Mada Medan. The results showed that: 1) Worksheets for students that were created using a realistic mathematical method to enhance their problem-solving skills and self-efficacy satisfied valid, practical and effective; 2) An upsurge in the N-gain value from 0.35 in trial I to 0.39 in trial II indicates an improvement in problem solving skills achieved by the use of worksheets designed using a realistic mathematics learning procedure and then 3) Trial I's N-gain value of 0.31 indicates that students' self-efficacy has improved through developed realistic mathematics instruction; in trial II, this value increases to 0.40.
