Abstract

This study is aimed at producing a learning tool for statistics of junior high school using realistic mathematics education approach which includes valid and practical lesson plans (RPP) and students worksheets (LKS) to develop mathematical literacy skills. This development research refers to the 4-D development model from Thiagarajan which consists of define, design, development, and disseminate stages. The test subjects were seventh grader students of SMP Negeri 8 Pekanbaru. The data ware obtained using validation sheets by experts and students' response questionnaire sheets.
