Abstract

This study aims to analyze the effectiveness of the PQ4R learning method on learning outcomes of students' knowledge and reading skills. The design in this study used posttest only control group with 2 classes taking techniques. Class X-1 as a control class and X-2 as an experimental class using the PQ4R learning method. Data analysis techniques used descriptive analysis to determine the completeness of the learning outcomes of the experimental class. Test the improvement of student learning outcomes with N-gain values. Comparative hypothesis testing with paired t-test samples and reading skills with a questionnaire and observation. The results of students' mastery learning showed that only 10 students out of 35 students reached KKM. Tests for improving student learning outcomes indicate a medium category. The comparative hypothesis test shows the asymp.sig value of 0.001, which means that there are differences in the learning outcomes of the control class and the experimental class. And students' reading skills show the distribution of questionnaires that agree and the observation sheets are categorized as good. The conclusion of this study is that the PQ4R learning method is better than the class that does not use the PQ4R learning method on student learning outcomes and reading skills on ecosystem material.

Abstract

Natural Science is the study of the phenomenon that occurs in the student environment. Directly oriented learning in the student environment makes learning meaningful because students can see the real object being studied. Based on the observations in SMP Negeri 5 Pekalongan, learning activity has not utilized the environment as a learning source. Whereas the location of the school near the appropriate learning sources to study environmental pollution material. Student learning outcomes are less than optimal and students tend to be passive. Therefore, variations are made in the learning by utilizing the Kalibanger River as a source of learning environmental about environment pollution. The method used in this research is quasi experimental design type nonequivalent control group design. Determination of the sample is done by purposive sampling technique and used as experimental class is class VII F and control class is class VII D. Student retrieval data using test instrument, while student activity is taken from observation sheet and questionnaire. Learning result data obtained by posttest value is higher than pretest. Increased learning results occur due to learning activities undertaken by students. Recapitulation of experimental class student activity is 87,9% which belong to very active criteria. Based on the results of t-test calculation obtained t-count = 3.323> 2.040 so H1 accepted, it can be concluded learning Kalibanger river utilization as a source of learning about environmental pollution can increase the activity and learning outcomes of students of SMP Negeri 5 Pekalongan.
