Abstract:

The aim of this study is to evaluate the effectiveness of the instructional design developed to increase the knowledge and awareness of third-grade students about what garbage/ waste is, the importance of throwing the garbage/ waste to the right place, and the recycling processes of waste. In this study, which was designed as a pilot study, the effect of the developed instructional design on students was tested using a single-group post-test design. There are 54 teachers and three 371 students in the study group. The data were collected through student worksheets and teacher opinion form prepared by the researchers.The results of the research showed that after the training, the students became aware of the waste and garbage separation and frequently used the importance of reducing the garbage in their answers. It was determined that the students stated that the waste and garbage, which are unconsciously thrown into the environment without being separated, cause environmental pollution, and they emphasized individual precautions in their solution proposals. The majority of teachers' views on instructional design are positive. As a result, it has been determined that the developed instructional design serves the purpose, the activities are appropriate and applicable to the class level, and the time allocated to the activities is sufficient.
