TABLE 1. Practices to maximize student learning from educational videos

Finally, the utility of video lessons can be maximized by matching modality to content. By using both the audio/verbal channel and the visual/pictorial channel to convey new infor-mation, and by fitting the particular type of information to the most appropriate channel, instructors can enhance the germane cognitive load of a learning experience.

Weeding, or the elimination of interesting but extraneous information that does not contribute to the learning goal, can provide further benefits. For example, music, complex back-grounds, or extra features within an animation require the learner to judge whether he or she should be paying attention to them, which increases extraneous load and can reduce learn-ing.

The benefits of signaling are complemented by segmenting, or the chunking of information in a video lesson. Segmenting allows learners to engage with small pieces of new information and gives them control over the flow of new information.

Signaling, which is also known as cueing (deKoning et al., 2009), is the use of on-screen text or symbols to highlight important information. For example, signaling may be provided by the appearance of two or three key words (Mayer and John-son, 2008; Ibrahim et al., 2012), a change in color or contrast (deKoning et al., 2009), or a symbol that draws attention to a region of a screen (e.g., an arrow; deKoning et al., 2009).

Now one feels blithe as a swimmer calmly borne by celestial waters, and then, as a diver into a secret world, lost in subterranean currents. Arduously sought expressions, hitherto evasive, hidden, will be like stray fishes out of the ocean bottom to emerge on the angler’s hook;
