The use of Videos clips technology during instruction is growing and is thought to be one of the most effective way for supporting instruction. Videos, for example, engage both the sense of sight and hearing of the learner simultaneously. This in turn reduces the cognitive load on the learner during the learning process. However, numerous research have shown that a poorly designed video can sometimes become a barrier to learning rather than promoting it. This implies that educational videos ought to comply with 'video pedagogy' to enhance learning. A question therefore emerges: How can we design an effective instructional video that support and enhance learning?
To answer the question, i suggest five essential design guidelines to observe when designing such a video:
1. Objective- this simplifies the learning process and draws learner attention and interest.
2. KISS (Keep It Short and Simple)- "less is more, more is less". If content is long, do mini-videos.
3. Use Voice-over- they support learning for the blind or those busy with other physical activities
4.Captions- they are effective attention signals and can support learning for those with hearing impairment
5. Interactive videos- they engage the learner e.g. you may use Vizia to add quizzes as video plays
In the near future i will post a sample of video that aligns with these guidelines. Remember, just bringing technology in front of your students will not guarantee their engagement in your lesson.
