Development model learning device problem solving material arithmetic sequence learners SMA State Kakas

Abstract

This study aims to produce mathematics learning instruments on the Arithmetic Sequence lesson using problem-solving learning with a realistic mathematics approach to the 11th graders at SMA Negeri 1 Kakas that meets the criteria of validity, practicality, and effectiveness. The method of this study applies a modified 4-D model of research and development to design a lesson plan, student worksheet, and learning outcome test. Results find out that at the design phase, the lesson plan, student worksheets, and evaluation of learning outcomes were modified and revised. The results of field trials show that some aspects of learning are effective, and revisions are carried out by revising learning tools to produce final tools, the evaluation of learning outcomes seen from the index of validity and reliability is feasible without any significant revisions. The developed learning instrument by using problem-solving learning with a realistic mathematics approach was effective in teaching the Arithmetic Sequence lesson.
