Abstract

Video presentations, also referred to as mini-lectures, micro-lectures, or simply video lectures, are becoming more prominent among the strategies used in hybrid or fully online teaching. Either interested in imitating a Khan Academy style of presenting content or responding to other pedagogical or administrative needs, there are more instructors now considering the creation of short video lectures for their courses than before. This chapter examines the use of video lectures in online and hybrid courses, describes the design and application of them in graduate and undergraduate courses, and analyzes primary and secondary data results to expose strengths, weaknesses, opportunities, and challenges experienced in the development and implementation of this technique. The use of short video lectures is a regular practice in MOOCs and has the potential of becoming a successful practice, especially with the expansion of new approaches such as the flipped classroom.

Background

Mini-lectures are short videos purposefully fragmented, and grounded on cognitive principles such as the strategy of ‘chunking’ content into meaningful pieces, a practice that increases the probability of recall (Miller, 1956). Mini-lectures have the potential of becoming a successful practice especially in large enrollment campus courses as well as in fully online courses, especially with the expansion of new approaches such as the flipped classroom and MOOCs. They used to be commonly associated with online instruction, but in reality mini-lectures have become part of any mode of instruction, including fully face-to-face courses that use flipped learning approach. While some authors have described them as “60-second presentations” (Shieh, 2009), there are some that are 1-3 minutes long and they are called “micro-lectures”, and there are some that are a longer like 4-8 minutes long and they are also known as “mini-lectures.” They are shorter than a traditional +30-minute lecture in a face-to-face meeting, therefore the names “mini” or “micro” suits the concept well. Micro or Mini-lectures are short, to the point and focused on one topic at time. They probably started as an attempt to include instructor’s presence in online learning (Shea & Bidjerano, 2009) by imitating the “long standing educational tradition of lecturing” (Morris, 2009). The concept of mini-lecturing captured global attention in a Chronicle of Higher Education article (Shieh, 2009) titled “These Lectures are gone in 60 seconds.” Sheih described mini-lectures as one- to three-minute videos specifically formatted to online and mobile learning courses. The author credited the design of the format to David Penrose for San Juan College, Farmington, NM, although other instructors have also advocated a similar lecture model (McGrew, 1993; Shieh, 2009).

Key Terms in this Chapter

Video Lecture: A video recording of a lecture, conference or presentation by a professor.

Chunking: A term used in instructional design to refer to cropping or cutting content to meaningful short pieces.

Lecture capture: Refers to the technique used for video recording of complete class in session. The technique consists of using a camera in one end of the classroom that will capture everything that happens in a class, from beginning to end.

Micro-Lecture: A 60 seconds video lecture that focus on key concept/s.

YouTube: (a) Online platform publicly available to host video recordings from any source. (b) The company that owns the platform.

Mini-Lecture: A short video lecture that does not exceed 8 minutes.

Screen-Capture: The technique used to capture a computer screen in image or video, and the software that does that.

Khan’s Academy: The company and online software that produces and hosts publicly available online classes and tutorials on different subjects.

Screencasting: The act of capturing action on a computer screen while the action is being narrated. The result is a video recording.
