Definition
Roger Schank (born July 7, 1942) is an American artificial intelligence (AI) researcher, cognitive psychologist, learning scientist, and entrepreneur. He is noted for his work on case‑based reasoning, script theory, and the development of educational technologies that emphasize experiential learning.
Overview
Schank earned his Ph.D. in cognitive psychology from the University of Michigan in 1972. His early academic career included positions at the University of Pennsylvania and Yale University, where he conducted research on natural language processing and the representation of knowledge. In the 1980s, he founded the Institute for the Learning Sciences (ILS) at Northwestern University and later the Knowledge Systems Laboratory (KSL) at the University of Texas at Austin. Schank’s interdisciplinary work bridges AI, psychology, and education, influencing both theoretical research and commercial ventures. He has authored numerous books, including Teaching Writing: A Psycholinguistic Approach (1972) and Dynamic Memory: A Theory of Learning in Computers and People (1990).
Etymology/Origin
The surname “Schank” is of Germanic origin, derived from the Middle High German word schanc meaning “drawer” or “cabinet,” historically indicating an occupational name for someone who worked with storage furniture. “Roger” is a given name of Germanic origin, composed of the elements hrod (“fame”) and ger (“spear”).
Characteristics
-
Case‑Based Reasoning (CBR): Schank pioneered CBR, a problem‑solving methodology that uses specific past cases to inform the solution of new problems. This approach contrasts with rule‑based systems and has been applied in domains such as legal reasoning, medical diagnosis, and customer support.
-
Script Theory: Introduced in the 1970s, script theory proposes that human knowledge is organized into structured sequences of events (“scripts”) that guide understanding and expectation in everyday situations. Scripts have been influential in natural language understanding and narrative generation.
-
Experiential Learning: Schank advocated for learning environments that simulate real‑world tasks, arguing that knowledge is best acquired through active engagement rather than passive instruction. His work led to the creation of educational software such as the “Intelligent Tutoring System” and the “Mindspark” platform.
-
Entrepreneurial Ventures: He founded several companies, including Cognitive Systems, Inc., which developed AI products for industry, and Socratic Arts, a firm focused on immersive learning experiences. Schank’s entrepreneurial activities aim to commercialize his research on AI and learning science.
-
Publications and Influence: Schank has published over 150 scholarly articles and multiple books. His concepts have been cited extensively in AI literature, cognitive psychology, and instructional design. He has also been a vocal critic of traditional schooling models, promoting alternative approaches that emphasize problem‑based learning.
