Abstract

Critical thinking skills in students XI Grade Science of Senior High School 7 Bandar Lampung not developed. This is because learning process dominated by teacher. One alternative that can be used to make students active in critical thinking is PBL models. The purpose of this study were to determine the effect of PBL models to the students' critical thinking skills. The design was a pretest-posttest non-equivalent. The samples in this study was students of XI Grade Science 2 and 3 where selected with clusster random sampling technique. The data of this study is in quantitative and qualitative data. Quantitative data obtained from the average value of the pretest, posttest, and N-gain statistically analyzed using t-test. Qualitative data taken from student learning activities observation sheet, and then analyzed descriptively.The results showed that the use of PBL models improve students' critical thinking skills with the average pretest score (24.11), posttest (68.95), and N-gain (59.86).Student learning activities that use the models PBL also increased from meeting I with an average of 55.09 to meeting II increased with an average of 69.91, and rise again on third meeting with the average of 80.32. Thus, application of the model PBL influential in improving critical thinking skills by students.Keywords: PBL Models, critical thinking skills, learning activities, and circulatory system.

Abstract

One effort to improve the learning outcomes of natural science subjects, the researchers are interested in examining the effectiveness of cooperative learning. According to the theory of constructivism, learning is a construct knowledge based on prior knowledge. Thus, the ability to beginning students could be expected to affect the learning outcomes. Researchers applying two cooperative learning model type is the type Student Achievment Team Division (STAD) and Group Investigaton (GI) and the two classes. The technique used in this study is proces sampling techniques, and data collection and processing be conducted to obtain data on knowledge and attitudes. The instrument used was a test sheet and questionnaire. To analyze the data the normality test, homogeneity test, t test, and N-gain.Result of different of average from pretest and postest score get 60 percents for experiment class (STAD type) and 40 percents for control class (GI tipe). Result from average scores of questionnare get 70 percents for experiment class (STAD type) and 40 percent for control class (GI type). From the result of count above show that there is significant different and positive influence between knowledge result and student attitude which using coopertative learning model of STAD and cooperative learning model of GI.Keywords: Conservation, STAD learning model, GI, students' Knowledge, Attitudes of students, Mangrove Conservation
