Egan et al. Study
Results:
- Subjective ratings:
- Superbook users rated it easier than paper (5.8 vs. 3.1 out of 7)
- Superbook users gave higher ratings on the stat system
- Incidental learning:
- Superbook users recalled more chapter headings
- maybe because these were continually displayed
- No other differences were significant
Problems with study:
- Did not compare against non-hypertext computerized version
- Did not show if/how hyperlinks affected results
