ContentBrief overview of our cognitive architectureOrganized knowledge base and cognitive loadWhat instructional methods are best for whom? (Expertise reversal effect)Instructional implications and research problems ICLEPS 29 August 2005
Review of our cognitive architecture Cognitive studies of expertise: Knowledge base in LTM is central to cognitive processing ICLEPS 29 August 2005
Review of our cognitive architecture Knowledge base in LTM affects the way we process information in WM and solve problems: Novices: weak problem-solving methods Experts: retrieval and application of previously acquired LTM knowledge structures ICLEPS 29 August 2005
Organized knowledge base and cognitive load WM is very limited when dealing with novel information(novices) WM has no known limits when dealing with information that has been organized and stored in LTM(experts) ICLEPS 29 August 2005
Organized knowledge base and cognitive load Long-Term Working Memory (LTWM) Executive function of LTM knowledge structures ICLEPS 29 August 2005
What instruction is best for whom? (Expertise reversal effect) Instructional designs or procedures that are effective for novices may be ineffective for more expert learners Kalyuga, S., Ayres, P., Chandler, P., & Sweller, J. (2003).

What instruction is best for whom? (Expertise reversal effect) Instructional techniques and procedures need to change dynamically with alterations in expertise. Previous ideas (Aptitude-Treatment Interactions) and recent developments. EARLI 2005: P. Ayres; R. Atkinson; R. Bruenken; A. Renkl; N. Schwartz. Mk ICLEPS 29 August 2005
What instruction is best for whom? (Expertise reversal effect) Adaptive learning environments (tutors in algebra and kinematics) were compared to equivalent tutors without real-time adaptation of instruction to the level of learner knowledge Kalyuga, S., & Sweller, J.

Instructional implications and research problems • more efficient instructional design • decisions (micro- a macro- levels) • adaptive e-learning with optimized • cognitive load (learning without ‘headache’): • efficiency-based approach • overcoming the narrow view of expertise • and organized knowledge structures • role of constructive (germane) cognitive • load and motivation in expertise acquisition ICLEPS 29 August 2005
