My work focuses on facilitating positive interactions among students in contexts of Computer-Supported Collaborative Learning (CSCL) and designing effective instructions for computational thinking (CT). My research accomplishments and interests emphasize innovative uses of instructional technologies to establish learning communities and enhance learning performances. Overall, my research impacts understanding learners’ collaborative learning processes, designing effective learning environments, fostering productive learning communities, and enhancing problem-solving performances in various contexts. I have contributed to knowledge in this area by conducting empirical studies that observed learning processes and evaluated students’ mental models, which provided insights to design more effective, efficient, and engaging instructions.
