Comparing Examples: WebAssign versus Textbook*

Research shows students can learn from worked examples.$^{1}$ This pilot study compared two groups of students' performance (10 each) in solving physics problems. One group had access to interactive examples$^{2 }$released in WebAssign$^{3}$, while the other group had access to the counterpart textbook examples. Verbal data from students in problem solving sessions was collected using a think aloud protocol$^{4}$ and the data was analyzed using Chi's procedures.$^{5}$ An explanation of the methodology and results will be presented. Future phases of this pilot study based upon these results will also be discussed. $^{1}$Atkinson, R.K., Derry, S.J., Renkl A., Wortham, D.
