When reading the research on Curiosity, Involuntary Curiosity is of particular interest to us teachers.
Defined by Loewenstein (1994) as curiosity that "...arises spontaneously as a result of a curiosity inducing stimuli", it isn't difficult see how honing the art of curating such moments is a powerful lesson planning tool.
Specifically, editing a video to reveal only a specific portion of a clip is a useful technique.
Often times a powerful video, if showed in its entirety, can simultaneously engage AND demotivate students by "inducing" curiosity, while also explaining the content that underlies the phenomena.
Rather than showing the entire video, the goal is to strategically curate the perfect portion of a video clip to tunnel students into asking the question you want them to ask.
To intentionally withhold the perfect amount of information.
