Mathematics Learning Tools Development Based on Problem Based Learning (PBL) to Increase Students Problem Solving Ability in Senior High School

摘要

This research is a development research using Plomp model which consists of three phases that are initial investigation phase, development and assessment. Devices developed RPP and LKPD based Problem Based Learning (PBL) to improve problem solving skills. Learning devices are tested in high school class XI students. Based on the results of the analysis, it can be concluded that the learning device of mathematics are valid, practical and effective.
