Are Electronic Textbooks As Effective as Printed?
Daniel, D. B., and Woody, W. D. (2013). "E-textbooks at What Cost? Performance and Use of Electronic vs. Print Texts." Computers & Education, 62(0), 18-23.
• No significant difference in learning • Electronic formats take longer to read

What Happens to Proximity in Engineering E-Textbooks?
Printed Spread

• These results can be used to infer proximity in PDF versions viewed one page, rather than one spread, at a time.
• Flowable-text versions have much lower proximity with some approaching 0%.

Returning to the Ideal
“… page after page of Leonardo’s manuscripts have a gentle but thorough integration of text and figure, a quality rarely seen in modern work.” Edward Tufte

Conclusions and Recommendations
• Proximity matters in scientific texts.• Electronic textbooks have poor proximity
(50% or worse).• Current-generation e-textbooks in science
and engineering should not be pushed.
