The Cognition & E-Learning Lab (CELL) is led by Dr. Meng-Jung Tsai who is currently a Professor in the Program of Learning Sciences, National Taiwan Normal University. Prof. Tsai's research centered at how students learn in various digital learning environments, especially in online inquiry learning, game-based learning and robotics-based learning environments. Her research domains cover from computer and information literacy education to technology-enhanced science learning. Most of her research topics involve online information searching and problem solving in relation to social scientific issues. She is also interested in social cultural issues such as gender difference and digital divide in technology society. Recently, Prof. Tsai has been using eye-tracking techniques to examine learners' cognitive process and cognitive strategies involved in digital learning environments. Her research team has developed the real-time eye-fixation data collection system, RealGaze (RG), and the Web-based Eye-tracking Data Analyzer, WEDA, to deeply analzye and visualize eye-tracking data. She is interested in using the new tools to bridge the relationships between students' visual behavior patterns and their learning outcomes, which further contribute to develop adapted learning environments. Another research line is focused on developing robotics-based interdisciplinary STEAM curricula rooted in computational thinking and design thinking frameworks to enhance all students' 21st century literacy. She has also made efforts in promoting K-12 teachers' professional development in robotics STEAM curriculum design.
