What is a Worked Example? A step – step demonstration of how to perform a task or solve problem (Clarke, Nguyen & Sweller, 2006) Reduce load in working memory Efficient for learning new task
Learning by Worked Example? Present A Problem Work Out The Solutions Explain why various steps are taken the rationale for the steps Attain the principles & steps in solving new problems Clarke, Nguyen & Sweller, 2006
Evidence Base- Advantages Theoretical – Worked examples • Aid Transfer (Meier, 2008) • Reduce Effort (Paas et al 1994) • Lessen Time (Lim & Moore,2002; Sweller et al 1985) • Reduce Cognitive Load (William, 1992;Geriet et al 2008) • Fewer errors (Lim & Moore,2002)
Amazing Result! Based on text Wollongong 3-year math course was completed in 2 years by emphasizing worked examples Zhu and Simon (1987)
Using a Tablet to Createworked examples • Some Strategies: • Instructor • Instructor Voice Over • Expert-novice • Peer-to-Peer (alternative perspectives) • Multiple Method • Think out loud • Review Before
Be careful --- Related theory: Cognitive load theory -Intrinsic cognitive load (ICL) is the mental work imposed by the complexity of the content” (Clark, Nguyen, & Sweller, 2006, p. 9). -extraneous cognitive load (ECL) resulting from poorly designed instructional material (Sweller et al. 1998)
Try to • Minimize cognitive load when you create worked examples by using Tablet How ???
Avoid • Redundancy Effect:
And • Split Attention:
My Supervisor Dr. Anne porter ALTC project Thank you
We still have lots to do…THANKYOUQuestions? • Ali Algarni • Contact ahsa736@uow.edu.au • http://www.math.uow.edu.au/subjects/summer/index.html
