Subclaims¶

q2 i? The review reports, citing Sugar, Brown, and Luterbach (2010), that screencasts vary in screen movement (static or dynamic, following the cursor) and narrative type (explicit action description or implicit activity description). → Chorianopoulos 2018 q2 i? The review reports, citing Cross et al. (2013), that learners preferred handwriting over typefaces but considered typefaces more legible, motivating a hybrid that fades handwriting into typeface once a word is complete. → Chorianopoulos 2018 (2)

Evidence¶

Chorianopoulos 2018¶

Chorianopoulos, K. (2018). A Taxonomy of Asynchronous Instructional Video Styles. International Review of Research in Open and Distributed Learning, 19(1). https://www.irrodl.org/

q2 · i? · theoretical · r2

Narrative review attributing to Sugar, Brown, and Luterbach (2010) an analysis of instructional videos based on the screencasting style, i.e., recording of screen. The review presents these two typologies as that study's findings about low-level instructional-media elements.

"They found that there are two types of screen movement: static or dynamic (follows the cursor). They also found that there are two types of narrative: explicit that describes the exact actions on the screen and implicit, which describes the type of activity on the screen"

Chorianopoulos 2018 (2)¶

Chorianopoulos, K. (2018). A Taxonomy of Asynchronous Instructional Video Styles. International Review of Research in Open and Distributed Learning, 19(1). https://www.irrodl.org/

q2 · i? · theoretical · r2

Narrative review attributing to Cross, Bayyapunedi, Cutrell, Agarwal, and Thies (2013) a comparison of hand writing to typefaces in digital-writing instructional videos. The hybrid fade approach is that study's own proposal, reported by the review.

"They found that learners preferred handwriting, but they considered the typefaces more legible, so they proposed a middle of the road approach that fades hand-writing into a typeface as soon as a word is complete"
