Objective: The purpose of these experiments was to examine the effects of user characteristics on learning from scrolling interfaces.
Background: Although scrolling Web pages are now common, few studies have explored the effects of scrolling on understanding the content that is being conveyed.
Method: This set of studies investigated whether presenting text in two particular formats has an effect on comprehension for readers who differ in working memory capacity.
Results: Results from both studies indicated that a scrolling format reduced understanding of complex topics from Web pages, especially for readers who were lower in working memory capacity.
Conclusion: These findings show that the way text is presented can interact with learner abilities to affect learning outcomes.
Application: These results have implications for both educational technology and human interfaces that present information using displays that can vary in size and construction.
