The inclusion of audio/video/podcasts into courses are used to increase student engagement. Blooms taxonomy of learning domains provides theoretical base to support the addition of audio and video into courses (Oomen-Early, et al, 2011). This theory proposed three types of learning: cognitive, psychomotor and affective. The affective domain involves feelings and attitudes and "learning, retention and intrinsic motivation is positively impacted when learners are emotionally engaged"(Oomen-Early et al, 2011, p.54). The other theory that supports the use of video/audio in courses is social presence. Social presence states that social engagement connects instructor to learner and learner to learner. The use of audio/video in a course allows the instructor to provide verbal feedback which gives a perception of social presence (Oomen -Early, 2011, p. 54).
There are several pros and cons to the use of audio/video/podcasts in courses. Some of the pros include:
- Cater to different learning styles (King, 2011, p. 36).
- Students with hearing or attention deficits can play back recordings for review (King,2011, p.37).
- Content is accessible 24/7
- Students take initiative for their learning and become independent learners (King, 2011, p.39).
There are also several cons for the use of audio/video/podcasts and they include:
- Learners gain nothing except review of content (King, 2011, p.37).
- Podcasts could just be lecture webcasting (King,2011, p.37).
- Quality of education could be compromised (Oomen-Early,2011, p.51).
- Not all students have access to internet and software.
I have used different podcasts for both education and pleasure for many years. There was a radio personality located in Chicago who I listened to for many years. When he was fired from the radio station, he provided daily podcasts of his show which I downloaded to my iPod. I would then listen to them every afternoon. I do believe he still has them available. Another podcast that I use and recommend for my students is Kahn academy. They provide excellent short clips that can explain concepts for students. The site is especially helpful for math concepts.
I think the pros far outweigh the cons when it comes to adding audio and video to courses and presentations. I have been attending a conference this week and have paid close attention to the presentations and all of them had some type of audio or video clip. The engagement of the audience was evident.
