Abstract

The objective of this research was knowing the influence of  using group investigation learning model toword students activity and students learning result. The research designs were non equivalent pretest – posttest. The research sample were students in X1 and X3 class that was selected by purposive sampling technique. Data of the research were qualitative and quantitative. The qualitative data was gotten by students learning activity and questionnaire that was analyzed descriptively. The quantitative data were the average score of test, that was analyzed by t-test and U-test. The result showed that the students learning activity improve, they were teamwork (78.16), observation result presentation/group discussing (80.46), asking question (65.52), and creating conclusion (77.01). The students learning outcomes also develop, with N-gain average score was 56.91. It was mean, that using group investigation as the learning model influenced the improvement of students learning activity and students learning result in contamination and preservation of environment material.Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran group investigation terhadap aktivitas dan hasil belajar siswa. Desain penelitian adalah pretes-postes tak ekuivalen. Sampel penelitian adalah siswa kelas X1 dan X3  yang dipilih secara purposive sampling. Data penelitian berupa data kualitatif dan kuantitatif. Data kualitatif diperoleh dari aktivitas belajar siswa dan angket tanggapan siswa yang dianalisis secara deskriptif. Data kuantitatif diperoleh dari rata-rata nilai tes yang dianalisis menggunakan uji-t dan uji-U.

Abstract

 This research was aimed to know the effect of  problem based learning (PBL) teaching model towards student critical thinking skills and student responses about PBL teaching model. This research design was pretest-posttest non-equivalent. Samples were VIID and VIIE that was chosen by cluster random sampling. The quantitative data was obtained from student critical thinking skills (pretest, posttest, N-gain) and analyzed by using t-test and U-test. The qualitative data was obtained from questionnaire of student responses were analyzed descriptively. The results showed that PBL teaching model increased the average of  student critical thinking skills significantly (39,4 increased to 68,9 with N-gain 48,6). Majority of students (95,83%) feel happy to use PBL teaching model in environmental management material. Thus,  PBL teaching model was influenced significantly towards student critical thinking skills and influenced towards student responses about PBL teaching model. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran berbasis masalah (PBM) terhadap kemampuan berpikir kritis dan tanggapan siswa tentang penggunaan model pembelajaran PBM. Desain penelitian adalah pretes-postes non-equivalent. Sampel yaitu siswa kelas VIID dan VIIE yang dipilih secara  cluster random sampling. Data kuantitatif berupa kemampuan berpikir kritis siswa (pretes, postes, N-gain) yang dianalisis menggunakan uji-t dan uji-U. Data kualitatif berupa angket tanggapan siswa yang dianalisis secara deskriptif. Hasil penelitian menunjukkan model pembelajaran PBM dapat  meningkatkan rata-rata kemampuan berpikir kritis siswa secara signifikan (39,4 meningkat menjadi 68,9, dengan N-gain 48,6).

Abstract

The problems in the learning process at Junior High School 13 Bandar Lampung is still dominating the teacher in the classroom. This results in low student concept mastery. cooperative learning model of STAD type to enable the students to learn so that students can increase mastery of concepts. The purpose of this study was to determine (1) the use of cooperative learning model type STAD significantly affect students mastery of concepts in the subject matter of the respiratory system in humans. (2) the average students mastery concepts using cooperative learning model STAD type of subject matter in the human respiratory system is higher.  (3) students learning activities using cooperative learning model STAD type of subject matter in the human respiratory system is higher. The sample in this study was VIIIC and VIIIE graders who were randomly selected by cluster random sampling technique. The results showed an average N-gain of the experiment class is 50.74 higher than the control class is 32.05. Test t1 to N-gains obtained on the tcount(-5.224) ttable(2.000) so that H0 is rejected. That is an average of N-gain in the experimental class significantly different from the average N-gain the control class. Then t2 test results show that tcount(19.343) ttable(2.042) so that H0 is rejected. That is an average of N-gain in the experimental class higher than the average N-gain the control class, so that students mastery of concepts can be expressed on the subject matter of the respiratory system in humans using cooperative learning model of STAD type is higher than the model of learning directly. Keywords: STAD, students mastery of concepts, the respiratory system.
