Abstract
This research aimed to examine the effect of guided discovery learning model against Junior High School students mathematical problem solving ability and the difficulties experienced by students in solving mathematical problem solving test. Quasi-experimental research was conducted in SMP Negeri 6 Karawang Barat by taking two classes as the research samples. First class is VIII B amounted to 32 respondents as the control class and VIII E amounted to 34 respondents as the experimental class. Researcher provided treatment that guided discovery learning for the experimental class and conventional learning for the control class. After being given the treatment, then researcher conducted posttest for mathematical problem solving ability in both classes. This research quantitative data analysis using Microsoft Excel aid. The results showed that there are significant effect of guided discovery learning model against Junior High School students mathematical problem solving ability, it is seen from the average of students mathematical problem solving ability who learned with guided discovery learning is higher than the average of students mathematical problem solving ability who learned with conventional learning and the results of effect size test in high category.
Keywords: Guided Discovery Learning, Mathematical Problem Solving Ability
