Nada Dabbagh is an assistant professor in the Instructional Technology program at George Mason University. She teaches graduate courses in instructional design, Web-based instruction, applied psychology, and technology integration. Her main research interests are the design and evaluation of Web-based instruction (WBI), problem generation and representation in problem-based learning (PBL), and the contextualizing of instruction through constructivist learning environments (CLE).

Nada received her doctorate in Instructional Systems Design (INSYS) from Pennsylvania State University in August of 1996. During her doctoral program she worked for the Applied Research Laboratory at Penn State as a senior training specialist, developing interactive, multimedia-based training modules (CBT) for the Warner Robins air force base. Prior to enrolling in the INSYS doctorate program, she was an instructor in computer science at Pennsylvania State University for six years. She taught courses in fundamentals of computing, programming, and algorithm development to liberal arts, business, and engineering students.

Prior to joining the faculty at George Mason University, Nada was awarded a technology fellowship in the Center of Instructional Advancement and Technology (CIAT) at Towson University. As a result of this fellowship she designed and developed a problem-based learning environment that exposes students to the contextual and problem-solving nature of instructional design. This research effort is ongoing with the goal of building a Web-enabled database of problem-based case scenarios to support the teaching and learning of instructional design through authentic contexts. A learning objects systems architecture will be used to develop this knowledge base. Currently, she is also working on evaluating the pedagogical effects of redesigning traditional courses for online delivery using Web-based course authoring tools. She recently published an article and a book chapter that articulate her findings on this issue. She is also writing a book entitled Online Learning and Web-Based Course Authoring Tools: Concepts, Strategies, and Application.
