The student’s scientific literacy is vital in improving students’ awareness of several issues. This study was intended to describe the effect of the SETS learning approach combined with Vee Diagram on students’ scientific literacy especially on Environmental Pollution Material. This study used a nonequivalent pretest-posttest control group design. The survey involved 60 students who were selected using cluster random sampling technique. The quantitative data, in terms of pretest, posttest, and N-gain scores were analyzed using Independent-sample t-test at the 5% significance level. The results showed that, based in the N-gain scores, the experiment class was classified in moderate category and the control class belonged to low category. This means that the SETS learning approach combined with Vee Diagram influence student’s scientific literacy on Environmental Pollution Material. Therefore, this combination is recommended to be implemented in class to enhance students' scientific literacy skills.

One of the factors of the low scientific literacy of students is influenced by the learning model used during the learning process. This study aims to determine the effect of the problem based learning (PBL) model using vee diagrams on environmental pollution material on students' scientific literacy skills. The sample consisted of 68 students, consisting of class VII 1 and VII 3 who were selected by purposive sampling technique. The research data were obtained from test questions and response questionnaires, the data were analyzed using the independent sample t-test. The results showed the average N-gain of science literacy abilities of students in the experimental class (0.48 ± 0.16) with "moderate" criteria and the control class (0.23 ± 0.13) with "low" criteria. This shows that learning using the PBL model using vee diagrams has a better effect on increasing students' scientific literacy skills. The results of the questionnaire response analysis had an average percentage was 88.8%.Keywords: Science literacy, problem based learning, vee diagram

This study aims to determine the effect of use of wet preservation Phylum of Molluscs and Echinoderms with Inquiry Learning on student learning outcomes. The method of this study was quasi-experimental with nonequivalent pretest-posttest control group design. The research samples were students of class X MIPA 1 and X MIPA 2 which were to 56 students that were selected by the Total Sampling technique. The type of data used were quantitative data and qualitative data. The instrument used in this study was in the form of multiple-choice questions, with the independent sample t-test SPSS 17.0 data processing technique. The results showed that the use of wet preservation Phylum of Molluscs and Echinoderms differed significantly on student learning outcomes in the experimental class with the control class. The average N-gain in the experimental class was 0.58, while the control class was 0.39, while the results of student responses to wet preservation Phylum of Molluscs and Echinoderms with Inquiry Learning have a good (78,57%) and very good (84,78%).

This study aims to produce a practical guidebook of human circulatory system with Argument-Driven Inquiry (ADI) model for students at junior high schools. The design of this research was R&D with 4-D model including define, design, develop, and disseminate. However, this research was only up to the develop step. The result of this study is in form of a practical guidebook of human circulatory system and using language that is easily understood and in accordance with EYD. Then, the practical worksheet consists of student identities, title of practices, basic theories, objectives, research questions, tools, materials, work steps, argumentation schemes, argumentation sessions, and reports. Next, the results of validation of experts and practitioners as well as the results of the readability test of the students obtain "Excellent" category. Moreover, the results of the implemented tests of all practices obtain "Almost All Activities Implemented" category. As a result, the practical guidebook of the human circulatory system with ADI model is valid and practical.
