Abstract

This student worksheet is designed with the aim of training students’ mathematical reasoning skills. This research is a type of Research and Development (R&D). The development model uses 4D namely, define, design, development, disseminate, but it is only limited to the development stage. The data in the study were collected by using a questionnaire and documentation. The research instrument used was the media expert validation sheet, the material expert validation, and the linguist validation using the Method of Successive Ratings (MSR) followed by the calculation of the index number to measure the validity of the student worksheets. The validation result from 6 validators show valid and feasible criteria to be tested in the field.
