This research is motivated by the large number of elementary school classrooms that do not offer quality science experiences to students so that it has an impact on students' low understanding of the science concept. The RADEC (Read-Answer-Discuss-Explain And Create) learning model seems suitable for increasing students' understanding of science concepts. This learning model has scientific stages that encourage the cons-truction of students' knowledge. This study aims to analyze the increased understanding of the concept of electrical phenomena through the application of the RADEC learning model. The study involved twenty-eight grade 5 students in the 2019-2020 academic year. Quasi-experimental method with one-group pretest-postest design was used in this study. To find out the understanding of students' concepts about electrical phenomena, tests were carried out before and after the implementation. This study uses descriptive analysis to analyze data collected before and after implementation. From the results of the analysis, it is known that students' understanding of the concept of electrical phenomena after the implementation of the RADEC learning model is higher than before. Thus, it can be concluded that the application of the RADEC learning model can improve students' conceptual understanding of electrical phenomena.

This study aims to determine the differences in critical thinking skills and environmental care attitudes among learners using an integrated environment-based learning model with which using conventional learning model. The method used in this research is quasi experimentwith Nonequivalent Control Group Design. The population in this study were all fifthgrader students of Dayeuhkolot 07 State Elementary School, Bandung Regency with the sample used were 40 students. The experimental group were given a treatment using an environment-based learning model, while the control group were given a conventional learning model. The instrument used in this study was a test to get insights into the critical thinking skills and questionnaires to get insights into the attitude of environmental care. Data analysis used in this study was independent sample t-test. The results demonstrated that (1) There was a difference in critical thinking skills among learners using an integrated environment-based learning model compared to those using a conventional learning model. (2) There was a difference of environmental care attitude among learners using an integrated environment-based learning model compared to those using conventional learning model. Therefore, it can be concluded that the application of integrated learning model based on environment can improve critical thinking skill and environmental attitude of learners.

Environmental care attitude is an important factor in protecting the environment. The Adiwiyata Award is presented as the highest recognition for implementing an environmental care attitude. The aims of this study are to (1) evaluate the execution of the environmental curriculum in Adiwiyata schools; (2) to analyze the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency using the new ecological paradigm (NEP) scale; and (3) to examine the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency related to gender differences. Based on the criteria of Adiwiyata schools, they were used as research subjects. The research subjects were chosen using a purposive sampling technique. A questionnaire was utilized as a data collection instrument. The new ecological paradigm (NEP) scale was used to assess environmental care attitudes. This study used a Likert scale to assess environmental care attitudes. The Mann-Whitney test was used to identify gender differences in environmental care attitudes. The results found that (1) Adiwiyata schools in the Pati Regency supported the implementation of environmental education in the curriculum, as well as participation in environmental activity programs and the use of greenhouses; (2) the environmental care attitudes of students from the SMA Negeri Pati Regency were in the moderate category; and (3) there was a gender difference based on environmental care attitudes, which found that female students have a higher environmental care attitude than the male students. Environmental education plays an important role in gender differences because the Adiwiyata school has integrated learning activities with the environmental education curriculum, and participatory-based environmental activities can improve students’ environmental care attitudes. The potential implication for policy and practice in the field is that humans will consciously prevent environmental problems from occurring.

A Japanese method in teaching at classroom show good result by implementing Kamishibai. On the other hand, technology is inseparable from daily life. Computer-based learning media innovations are fast and diverse, ranging from 2D animation to 3D environments. The hologram is one example of 3D object visualization to deliver the learning material. Based on Kamishibai's opportunity and hologram multimedia utilization to enhance the environmental education teaching activity, research about the adaptation of 3D pyramid hologram for teaching environmental education in elementary school is proposed. Firstly, the kamishibai model for teaching environmental education from Japan is explored and modified to fit Indonesia's condition. The kamishibai and hologram multimedia utilization in teaching environmental education has been experimented with in class. The results of learning kamishibai and multimedia holograms show that students will improve their abilities in environmental problems. The students lead the literacy and caring attitudes were following their level of knowledge and skills as well as their attitudes about caring about disposing of garbage in its place, learning to clean sewerage at school, learning to farm in the yard of schools, and understand how plants exist in school gardens.

Environmental education for sustainable development in Japanhas developed rapidly in recent years. Focusing on formaleducation, schools called “UNESCO School” play a leadingrole in environmental education for sustainable development.The school network approved by UNESCO was for promotinginternational understanding education, but it is currentlypositioned as an association of schools promoting ESD. Thispaper describes the establishment and development of theUNESCO School and focuses on the practices of the schoolswhich focuses on environmental education as ESD.
