Abstract

Chemistry is a subject that until now difficult to understand, because many abstract chemistry learning concept. The chemistry lessons are closely related to the laboratory, so that the students can do experimental activities and can understand chemical theories easily. However, if the school does not have a laboratory, does not mean that students can not perform experimental activities such as students in other schools that have a laboratory. The solution of the problem is that teachers should be more creative to creating active and fun learning so that students can be interested and motivated to learn. The use of experimental students’ worksheet based on CTL approach by utilizing the objects in our life is one alternative that can be done so that students can perform simple experimental activities. The purpose of this study is to determine the effect of the use of experimental students’ worksheet based on CTL approach by utilizing objects in everyday life. This research used Pre-Experimental Design with one-group pretest-posttest design. The population in this study were students of grade XI science program in senior high school of Village Community Resilience Institute (LKMD) Laha with a sample of 18 students. school of Village Community Resilience Institute (LKMD) is a private high school so that only a small percentage of students are schooling here because every year there are students who do not pass the school exam. The results showed that the average of student learning outcomes was 76.6 and 18 students were able to achieve the minimum mastery criteria (KKM). Data analysis in this research used simple regression analysis with PASW statistics 18. Regression equation obtained is Y = 1,139x - 8,535 with correlation coefficient 0,986 and t = -2,362. The result of regression analysis shows that experimental students’ worksheet based on CTL approach very influential on student learning outcomes and there are significant differences to pretest and posttest result, posttest was higher than pretest. Thus, Experimental students’ worksheet based CTL approach by utilizing objectsin everyday life can be used as one of alternative for school that do not have laboratory.
