Abstract

This research purposed to know the influence of using worksheet based on Guided Inquiry towards students CSP in junior high school on material of Global Warming. Research design was pretest-posttest of the nonequivalent group. Research sample were class VII.1 and VII.2 with purposive sampling technique. The students CSP data that were obtained from the score of pretest, posttest and N-gain were analyzed by t-test. The CSP qualitative data and the responses were analyzed descriptively. The research result was N-gain=76 17. The observation of students CSP was 83,2%. 81.45% of students gave the positive response to the use of the worksheet based on Guided Inquiry. Then, this worksheet based on Guided Inquiry had significant influence in increasing the students CSP on material of Global Warming.Penelitian ini bertujuan mengetahui pengaruh penggunaan LKS berbasis Inkuiri Terbimbing terhadap KPS siswa SMP pada materi Pemanasan Global.

Abstract

The purpose of this study is to determine the effect of the  laboratory-based learning toward   student  activitites and learning outcomes. The research  used  a pretest-posttest design. The samples in this study were student of class VIIIA and VIIIB   that  were randomly selected using cluster random sampling technique. The study collected quantitative data and qualitative data. Quantitative data  of  student learning outcomes obtained from pre test and posttest. Quantitative data  was analyzed using t-test at 5% confidence level. Qualitative data was  student activity  observed during laboratory-based learning.The results of this study showed that the  N-gain score of student  of experimental  class which using  laboratory-based learning was 60.51  higher than the average  N-gain  score of student of control class which  using discussion learning (49.71). Furthermore, the N-gain score of students' learning activities  of the experimental class reached 77.4 was higher than the control class that was 70.4. It can be concluded that the use of laboratory-based learning could improved student activities and learning outcomes of human digestive system concepts. Keywords: Lab-Based Learning, Student Activities, Learning Outcomes, Digestive System.

Abstract

The purpose of this research was to know the differences in learning outcomes of students cognitive and affective aspects between Guided Discovery Model with Guided Inquiry Model. The design of this research was the randomized pretest-posttest control group design. The quantitative data were obtained from pretest, posttest, N-gain that were analyzed by t test and U test. The qualitative data were affective aspect which obtained and analyzed descriptively using observation sheet. The result of this research showed that the average N-gain of experiment class II (71.21) with high criteria was better than the experiment class I (43.69) with medium criteria. Then, students result in affective aspect in experiment class II was 71.69 with good criteria, while the experiment class I was 68.75 with enough criteria. Thus, Guided Inquiry model is better than Guided Discovery Learning in improving student learning outcomes.Penelitian ini bertujuan mengetahui perbedaan hasil belajar aspek kognitif dan afektif siswa dalam menggunakan model Guided Discovery dengan Guided Inquiry. Desain penelitian ini menggunakan the randomized pretest-posttest control group design. Data kuantitatif, diperoleh dari pretest, posttest, N-gain yang dianalisis menggunakan Uji-t dan Uji U. Data kualitatif berupa hasil belajar aspek afektif yang diperoleh dari lembar observasi dan dianalisis secara deskriptif. Hasil penelitian menunjukkan rata-rata N-gain kelas eksperimen II (71,21) dengan kriteria tinggi lebih baik dibandingkan kelas eksperimen I (43,69) dengan kriteria sedang. Rata-rata hasil belajar aspek afektif kelas eksperimen II (71,69) berkriteria baik, sedangkan kelas eksperimen I (68,75) berkriteria cukup.
