Problem
• Programming by non-programmers– Psychology students build computer-based models
of cognitive psychology theories (typically in Prolog or Lisp)

Proposed Solution
• HANK - A visual programming language designed for psychologists based on principles taken from:– End-user programming– Software visualization– Psychology of programming
(Mulholland and Watt, 1998)

HANK Language
• Fact cards represent factual knowledge
• Questions query knowledge
• Instruction cards represent procedural knowledge

Research Questions
• Does cognitive modelling improve peoples understanding of cognitive psychology?
• Does HANK facilitate non-programmers to build cognitive models?
• Derive a set of guiding principles to support the design of programming tools for non-programmers

Approach
• Programming and Educational Walkthroughs– HANK and educational supporting materials
(Bell et al., 1991) (Lewis et al., 1998)
• Cognitive Dimensions– HANK (Green and Petre, 1996)
• Empirical Studies– Students’ understanding of a cognitive theory, attitudes
toward modelling and confidence in their understanding
