Experimental method is a method of learning in which students conduct their own experiments to prove theories that have been acquired in the classroom. Nevertheless unavailability of equipment and materials in the lab is sometimes used as an excuse vacuum laboratory activities. One effort to overcome this is to utilize the tools or chemicals that exist in the environment as a replacement of equipment and chemicals normally found in the laboratory. This method is known by the experimental method based environments.
The purpose of this study is to investigate the effect of the use of experimental methods based on chemical environment on learning outcomes of students SMA N 1 Wonosobo on the subject matter concept of oxidation and reduction reactions. All students of class X SMA N 1 Wonosobo 2009/2010 school year is a population study. The samples with cluster random sampling technique to produce the class as experimental group and X4 X5 class as the control group. Data collection was carried out in various ways ie, documentation, test, questionnaire, and observation.
The results obtained by an average of 79.76 experimental classroom learning outcomes, while the control class 73.01. The results of data analysis shows the effect of the use of environment-based experimental method to the redox chemistry student learning outcomes as indicated by the number of correlation 0.492. Conclusion of this research is the application of methods based ekeperimen learning environment influence the redox chemistry subject matter concepts class X SMA Negeri 1 Wonosobo with 24.23% contribution. Suggestions of this research is expected teachers to apply this method as a variation of learning dala, other than that teachers should also give a demonstration or explanation of what if the experiment is done by using existing materials in the laboratory
