Seyedahmad Rahimi, Ph.D., is an Assistant Professor of Educational Technology in the School of Teaching and Learning at the University of Florida. He is the director of Game-based Assessment & Measurement (GAME) Lab. Dr. Rahimi’s research focuses on assessing and fostering students’ 21st-century skills (e.g., creativity) and STEM-related knowledge acquisition (e.g., physics understanding). Toward that end, Dr. Rahimi designs, develops, and evaluates immersive learning environments (e.g., educational games) equipped with Stealth Assessment and Educational Data Mining, Learning Analytics, and Natural language Processing models. These learning environments can diagnostically assess students’ various competency levels, predict different outcomes, and act accordingly in real-time (e.g., adapt the game challenges to students’ level of competency or support students’ learning by triggering the appropriate learning supports). Dr. Rahimi is also actively researching various aspects of educational games (e.g., game mechanics, game difficulty, cognitive and affective supports, dashboard design, and incentive systems) and how they affect students’ motivation, performance, and learning.
