Kenney & Fisher (2017), (www.learntechlib.org/primary/p/178394/) reported preliminary research on their use of embedded questions in online presentations in a hybrid flipped classroom teaching scenario. In response to students seeming lack of attention in class and concerns about examination performance the idea was to pretest during the video presentation. This technique serves to make students to be more aware and present, being more active learners, and also to show students what the instructor thinks the important message is. In fact, Kenny & Fisher received feedback that 92% of students found that questions embedded in the presentation was helpful to them learning the materials. Active learning has been shown to be a more effective form of learning (Eggen & Kauchak, 2016).
The technology Kenney & Fisher utilized was PowerPoint videos with Camtasia Studio questions (https://elearningbrothers.com/blog/create-elearning-quiz-camtasia-studio/). A flexible and quick way for teachers to add questions to PowerPoint presentations is PollEveryWhere (https://www.polleverywhere.com/). This PowerPoint add-in allows several different question types and may be used by the instructor to see if the students are involved and understanding the materials.
Zang, et.al. (2016) found that video alone in online presentations did not improve student performance. As such, adding questions to the online videos is certainly worth testing for various classes and students to try to help their learning.
