Table 4 Examples of verbatim positive and negative usability comments related to intrinsic, germane and extraneous cognitive load (CL) types
Positive /negative | ICL-related | GCL-related | ECL-related |
|---|---|---|---|
Positive | “I really liked that whenever I forgot the definition of something, I could just click on the word and be reminded of the definition. That saved me a hell of a lot of time while reading […]” | “The connection of concepts really helps put main ideas together” | “the immense amount of graphs/figures provided” |
“I like that the vocabulary is underlined and if you forget a word, you can click on it and be reminded” | “I also really like the feature where you can ask the AI-book to compare topics. This was really helpful […] when I got confused on the similar terminology” | “Media hyperlinks are easier than having to go to a separate device to watch videos” | |
“Being able to click on various terms while reading to get definitions, explanations, etc. was really helpful” | “Connections of concepts to other chapters to build (or review) understanding to maintain learning foundation” | “Easy to use” | |
Negative | “Not enough inline [dotted] definitions” | “The AI is not good enough at answering basic questions related to the content” | “The search is [sic] works in a poor and frustrating manner: forcing me to use complete sentences […] (my habit is for words over sentences as this is the convention of all internet search nowadays […])” |
“Memorizability is still worse with this compared to a paper book due to lack of sense of location when reading” | “I think the search engine, while amazing, could be further tweaked to really break down the topics, specifically with the comparison feature” | “It seemed to take a long time for the answers to load after i [sic] submitted a query” | |
“Too many things to remember while using the AI-book” | “Connections between concepts not always made apparent. More depth would be useful” | “Only available on iPads and not online/Android” |
