What is your chemical creation to overcome environmental pollution? Students’ creative ideas on the RADEC learning model

This study aims to increase student creativity on environmental issues such as pollution by implementing the RADEC learning model. The study used a one-shot case study method with 25 7th-grade participants. Student worksheets, observation sheets, and interviews served as tools. Those instruments were used to track the development of their creative ideas during science classes. This data was triangulated for representative results. The results show that the RADEC learning model promotes student creativity. Students have come up with many ideas related to pollution solutions. Before and after the implementation of RADEC, students presented a considerable number of ideas. Most of these were dominated by posters that persuaded readers to keep the environment clean and use alternative energy. Some of them produced water purifiers, natural fertilizers, and solar ovens. Some of them showed the chemical concept of solidification of impurities. Although these ideas were not originally born and did not show many of the chemistry concepts, students were able to create solutions directly and showed fluency in reasoning
