This research method is Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research result is learning media in quiz and educational game using Word Wall for quadratic inequality, rational, and irrational material. The feasibility test of materials and media on quiz and educational game resulted in a percentage of 77% and 79,1% with a decent category. The attractiveness of quiz and educational game resulted in a percentage of 81% in the limited trial and 82,2% in the field trial, both of which were in the very interesting category. The results of the correlation test obtained a positive and significant correlation between student responses and student learning outcomes. The implication is that this development product can be used as a student learning tool, and it is recommended that teachers can develop Quiz and educational game using Word Wall on other materials.

This virus is growing very fast and spreading widely throughout the world. The country cannot be separated from this virus attack. More and more people have been exposed to the Covid-19 virus since the virus first entered Indonesia in early March 2020 (World Health Organization, 2020). This virus is getting worse and causing many sectors to be affected. One of them is the education sector, so the learning system that was initially implemented face-to-face becomes online learning. This change occurred due to recommendations from the government to stay at home, physical and social distancing, and always comply with health protocols (Kemendikbud, 2020).
