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

Low reading interest in high school students and the use of information and communication technology (ICT) are still not well integrated into learning. This is due to the lack of interesting biology textbooks and students’ habits in using gadgets for entertainment such as social media and games. For this reason, a solution to these problems is the development of pop-up books and virtual reality (VR) videos. This research uses the Research and Development method adapted from Borg and Gall by involving media and content experts for feasibility testing. The pop-up book and VR video evaluation were then carried out, the results showed feasibility without revision of 67% and some product revision suggestions. The results also showed the product responses to habits of mind (HoM) which included in the excellent category (3.7) from 100 students and 30 teachers even though preliminary test with a sample of high school graduates was still in the good category (3.2). Also, aspects of creative thinking are best between self-regulation and critical thinking. So, the implications of this research are pop-up book and VR videos are suitable as learning media also very good for improving students’ ha bits of mind.

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.
