Project 5: Worked Example
This worked example combines video, narration, and text in the form of multiple-choice comprehension and self-explanation questions to present a step-by-step demonstration of how to set up the grade center in the learning management system Blackboard. The applications I used were Loom and PlayPosit. This worked example is a redesign of my static multimedia tutorial from this post. The worked example is available on YouTube without the questions or below via PlayPosit.
Audience and Description of Topic:
The intended audience of this worked example is new-hire adjunct instructors in higher education. The worked example tasks them with setting up their own Blackboard grade centers for their respective courses. The worked example video covers the four initial steps in setting up the grade center, including removing unwanted columns, adding categories, creating a weighted column, and creating a grade column.
As these new hires typically do not have prior experience with learning management systems, their learning should not be negatively impacted by the expertise reversal effect from the worked example (Clark & Mayer, 2016, p. 247).
Creation Challenges:
I have previously used screen recorders and did not experience any technical issues using Loom to record the video. However, I have less experience using PlayPosit, and I had difficulties in changing the settings of the video, or "bulb," so that it could be viewed or embedded without users having to create an account to log in to the PlayPosit website. Initially, I created a sharable link, but the link expired and was no longer accessible after 24 hours. As PlayPosit is a freemium platform, that might explain some of my difficulty.
Analysis of Multimedia Principles:
This worked example represents a modeling example that provides a video-recorded narration accompanying the demonstration (Clark & Mayer, 2016, p. 242). To ensure that the viewers do not skip through the demonstration, this worked example includes multiple-choice self-explanation questions inserted through the platform PlayPosit that engage viewers and guide them to think about the practical application of the steps to their grading needs (p. 249). The PlayPosit platform allows learners to receive feedback about their answers and gives them the option to rewatch the video as needed when they submit an incorrect answer. In addition, the feedback is provided in the same window as the questions in order to apply the Contiguity Principle of keeping related content together (p. 96).

| Self-Explanation Question in PlayPosit |
This worked example demonstrates multimedia principles by adhering to the Contiguity, Modality, Redundancy, Multimedia, and Coherence Principles. It demonstrates the Modality and Redundancy Principles through utilizing audio narration over text to explain the steps of the demonstration. When no audio is playing, text is used to present the comprehension and self-explanation questions (Clark & Mayer, 2016, pp. 254-255). The worked example also demonstrates the Multimedia Principle by using video as a dynamic graphic accompanied by the spoken narration to help the viewers make sense of the steps and the purpose behind them at the same time (pp. 70-71). The example respects the Coherence Principle, as all audio communicates only the steps of the task to be accomplished and does not contain background music that could distract viewers away from the learning goal (p. 155; p. 168). The incorporation of these multimedia principles removes barriers from learning and keeps the viewer focused on duplicating the steps from the worked example as they accomplish the independent task of setting up their own grade center.
