In architectural and environmental design education, motivating students and improving learning outcomes are essential for developing necessary skills and creativity. Traditional teaching methods often fail to engage students effectively. Role-playing activities, showing benefits like increased engagement and critical thinking in various contexts, can simulate real-world scenarios, enhancing learning through experimentation. The study aims to provide data-driven insights into how different role-playing activities influence student motivation and identify the most effective methods for enhancing learning outcomes in architectural and environmental design education. This study employs a quantitative post-implementation research design to evaluate the impact of role-playing on learning outcomes and student engagement within the Department of Architecture and Environmental Design. The primary objectives are to assess how role-playing activities influence students' understanding of architectural and environmental design concepts, as well as their engagement and motivation. Data is collected through a structured questionnaire administered to students after participating in various role-playing activities within their courses. The variables include the type of role-playing activity, the students' understanding of concepts and their engagement and motivation, and the overall learning experience of the students. The post-implementation questionnaire utilises 10-point linear scale items to measure students' engagement, motivation, and perceived understanding, as well as multiple-choice and short-answer questions to assess specific learning outcomes. To achieve reliable results, a sample size of 157 students from a population of 244 is utilized, providing a 95% confidence level with a 5% margin of error. Data analysis involves descriptive statistics to summarize demographic data and questionnaire responses, and inferential statistics, including correlation analysis, to explore the relationships between the types of role-playing activities and changes in engagement, motivation, and understanding. The outcomes indicate the positive impact of role-playing on students' understanding of architectural and environmental design concepts and their engagement.
