Development of Atom Teaching Aids Made from Recycled Materials in Constructing Student Knowledge

Abstract

This study was conducted to develop teaching aids for atomic and molecular material. The use of teaching aids is expected to improve students' knowledge. This study used a research and development method. The development model used was the ADDIE model (Analyse, Design, Develop, Implementation, and Evaluate). The research was conducted from June to August at the Chemistry Education Laboratory, Indonesian Christian University. The teaching aids were implemented in the teaching of atomic structure at State Senior High School 48 in Jakarta. The results of the development show that the teaching aids received good to very good ratings from experts. In addition, testing on a small group showed that the teaching aids could be used effectively. Furthermore, implementation in the classroom showed an increase in student knowledge. Statistical analysis showed a significant difference, indicating that learning with the aid of teaching aids had a positive impact on student learning outcomes or knowledge (p<0.005). The conclusion of this study is that the teaching aids developed were rated good to very good, and that the teaching aids can help students construct knowledge about atomic structure, as indicated by the increase in student knowledge. Learning using teaching aids made from recycled materials can be an innovation for further research. The use of recycled materials will foster environmental awareness among students and teachers. Learning using recycled materials contributes to waste reduction and can facilitate schools with limited resources.
