The Effect of Contextual Teaching and Learning (CTL) Model With Outdoor Approach Towards the Students’ Ability of Mathematical Representation

This study aimed to determine the effect of implementation Contextual Teaching and Learning (CTL) model with outdoor approach towards students’ ability in mathematical representation. It was quasi-experimental research consisting two experimental classes one control group. used a pretest-posttest group design. The population this students SUPM Tegal. Sampling conducted using cluster random three classes. first carried out by implementing learning CTL approach. second CTL, while conventional model. instrument 7-point representation test form an essay. results were 1) affected improvement achievement higher than learning; 2) groups approach, respectively high, medium, low category.
