ICLEPS 29 August 2005 Content Brief overview of our cognitive architecture Organized knowledge base and cognitive load What 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 A N switch coil light 1. The Starter consists of a start push button, a stop push button and a switch activated by the coil. 2. Pressing down the start push button closes the circuit and allows the current to flow through the coil.. 3. The energised coil closes the switch, which provides an alternative closed circuit for the coil to that provided by the start push button. This circuit acts as a holding one: the start push button now can be released without breaking the current flow through the coil. 4. The light is operational, as the closed switch provides a closed circuit for it. 5. To cease operation of the light the stop push button is pressed. The circuit in the Starter is now open, the coil is no longer energised and the switch returns to its normal open position. Start Stop
