Development of Learning Materials Based on Problem Based Learning to Improve Students Problem Solving Ability

Problem Based Learning is a set of teaching
models that use problems as a focus for developing problem
solving skill. The purpose of this study is the produce qualified
learning materials which is developed based on Problem Based
Learning and analyze the improvement of students mathematic
problem solving ability which is learned using Problem Based
Learning materials. This research is a development research
using the Thiagarajan 4-D development model. Trials of
learning materials based on Problem Based Learning were
conducted three times to obtain quality devices. Based on the
analysis, Problem Based Learning based learning materials that
are taught have good quality at the stage of dissemination and
the ability to solve mathematical problems learned by using
Problem Based Learning devices is increased during the
disseminate stage. The results of the analysis of the data
obtained indicate that Problem based Learning materials can
improve mathematical problem solving ability.
