- Abstract
This study aims to: (1) Determine whether Think Pair Share (TPS) learning tools developed in grade VII of SMP Negeri 11 Medan are valid, practical, and effective. (2) Knowing whether students' mathematical representation ability through the use of learning tools can be improved. This type of research is a research development using the 4D model. The subject in this study was a Learning Kit that was developed consisting of student books, lesson plans, Student Activity Sheets, mathematical representation tests. The research subject is class VII. Data was collected in the form of instruments, namely validity sheets, questionnaire sheets, and tests. The results of the study obtained a valid, practical and effective learning device. (1) validation indicate that the device developed is suitable for use. Practicality can be seen from the response of the expert team or validator who stated that the learning tools can be used with minor revisions. The effectiveness seen from the classical completeness has met the minimum completeness criteria; (2) The trial shows that the mathematical representation ability increases as indicated by the n-Gain value.
