This type of research is qualitative research, the method used in this ...research is descriptive qualitative. The data used in this study was written data in the form of poems text document by 2019 PGSD students with environment themes. The results showed that in general these poems have the same theme that is telling the state of the environment. For the tone of the poem pinned in the poem indicates about the condition of the surrounding environment that is exposed to water, soil and air pollution which is a result of the results of fires, floods, landslides and others. This can also be observed from the poems that have been identified that generally have almost the same taste about disappointment and sadness. Other reviews made about the taste in the poem are gratitude, joy, disappointment, sadness, and anger. The last part of the analysis of the inner structure of poem is the mandate. The general mandate of the poem that has been analyzed is the mandate that human beings are obliged to maintain and preserve the surrounding environment for further survival.
This study aims to improve the learning outcomes of elementary school science students by using interactive multimedia on human skeleton material. This interactive multimedia is a learning media ...product in the form of an interactive CD. Based on information obtained by researchers that the lack of enthusiasm of students in science subjects, because students do not have a real picture of how the material process is explained. Therefore, this media is very important to support the learning process of science. The method used in this study uses the Research and Development (R&D) method with the 4D model which has 4 stages of development namely define, design, development, and disseminate. The results of the use of interactive multimedia on students showed that the average pretest score was 57.33 while the average posttest score was 84.17. Based on N-Gain of 0.60 in the medium category and it can be said that the effectiveness of interactive multimedia as a learning medium is classified as effective. Based on these results, it can be concluded that there is an increase in science learning outcomes for students of SDN 034 Taraibangun class IV using interactive multimedia on human skeleton material.
This study develops a learning trajectory with the Realistic Mathematics Education (RME) approach which is assisted by interactive multimedia that are valid, practical, and effective for learning KPK ...topics on PGSD UNRI students in low-grade mathematics subjects. The research method used is design research (design research), which is characterized by a cyclical process of preparing for the experiment, conducting the experiment, and retrospective analysis. This research is focused on designing the learning flow, validating it, and then testing it one-to-one and in small groups. The revised learning flow is then implemented in the classroom. Research data were collected through observation, interviews, checklist, video taping, analysis of student work, and tests. The collected data is analyzed by quantitatively and qualitatively. From the research that has been carried out, the KPK learning flow has been generated in the valid students of PGSD UNRI in terms of RME state-of-the art, content and construction. In its implementation, the learning flow that is designed can work in accordance with what was hypothesized, so students can rediscover concepts in the KPK topic through horizontal and vertical processes of mathematical process. The resulting learning flow is also effective in improving students' mathematical reasoning abilities.
