Facilitating information-seeking activity in instructional videos: The combined effects of micro- and macroscaffolding

作者：

Highlights：

• We studied the effects of scaffolding level on searching for information in videos.

• Micro and macro levels have specific effects on navigation and semantic searches.

• Combining the two levels of scaffolding facilitates the search activity.

• Results are discussed in terms of mental model building with or without scaffolding.
