摘要：This research aims at finding out the effectiveness of guided-inquiry learning model with Natural Environment Exploration (JAS) approach on students’ learning result of environmental pollution material.This recent study was conducted in MAN 1 Pati in the odd semester in academic year 2017/2018.The research design applied is non-equivalent control group design.The population for this research is the whole students in X MIA MAN 1 Pati which is divided into 5 classes,while the sample taken for this research was X MIA 1 and X MIA 4 selected by using purposive sampling technique.The result of this study showed that 86.96% of students in experimental class achieved score > 75 and there was a difference of mean in the posttest for experimental class and control class i.e consecutively 85 and 75.19.The result of t-test showed t count 0.000<0.05 which means there is a significant difference between control and experimental class.It also achieved N-Gain > 0.3 with the mean by 0.54.For the class control,65.38% of students accomplished > 75 and N-Gain 0.14.Based on the research result,it can be inferred that guided-inquiry learning with JAS approach is effective to improve students’ learning result for the subject material of environmental pollution.
