Assignment 1 – Create a Multimedia Enhanced Lesson

Hi Everyone,

My presentation can be found here with the corresponding explanation below.

 

For my multimedia lesson I chose to use a variety of multimedia tools including graphics, sound and video that I believe is pedagogically sound and informed by the principles of both Mayer (2014) and Clark and Lyons (2010)

For my overall presentation, I elected to use Prezi to create a multimedia presentation that can be easily shared with a link and opened in a variety of web browsers.  I liked Prezi because it was similar to a PowerPoint presentation however because it was web based, it was easier to upload sounds, videos and graphics and have them retain their functionality.  I also liked that Prezi allowed the learner to advance the slides at their own pace and the learner could easily move backwards and forwards in the presentation as needed.  This would correspond with Mayer’s (2014) segmenting principle in which “people learn better when a complex lesson is presented in manageable parts.  Learners can fully digest one segment of the lesson before moving on to the next segment.” (p. 393). 

 

For the graphics (slides 3 and 4) I used static illustrations that followed the principles of interpretive graphics that “help learners build understanding of events or processes that are invisible, abstract or both” (Clark & Lyons, 2010, pg. 19).  As it’s very difficult to visualize the inside of the mouth, throat and airway by just using words, I felt a graphic would lend to better understanding and visualization than just using words alone.  The two images I was using also served to explain the differences between and obstructed airway and an airway where CPAP therapy is being employed.  I elected to use two images that were exactly the same and then edited them to suit the information that I needed to present.  By using two visually identical images I feel as though it’s easier for the learner to discern the differences between them.  The graphics also have their corresponding explanations on the same slide as the graphic itself which according to the spatial contiguity principle (Mayer, 2014) will also assist with learning.

 

For the audio clips that I used (slides 7 and 8) I minimized the details and text on the slide to only what was absolutely necessary which correlates with Mayer’s (2014) coherence principle that recommends all extraneous material be excluded as it does not contribute to enhanced understanding.

For my video, I attempted to use the voice principle and the personalization principle, wherein I used my own voice instead of a computer generated voice and I tried to use a conversational style rather than a formal style of speaking (Mayer, 2014). The content in the video could have probably been presented in a variety of other ways; however I felt that the personal aspect of actually seeing the presenter try on masks and speak about them would lead to a better connection and better retention of material although seems like more research needs to be done before conclusions can be made. 

 

The Behind the Scenes

The two pictures for my presentation (slide 3 and slide 4) were found doing a google search for airway images that were not copyright protected.  The images were then edited using Sumo Paint (www.sumopaint.com/home/) to suit my educational needs, saved locally to my computer and uploaded into Prezi. 

The two sound clips in my presentation were created in two different ways.  The first sound clip (slide 7) was found on the internet and edited in Audacity to duplicate it (make it longer) and to fade the two duplicated clips together to make it more seamless.  The second sound clip (slide 8) I created by wearing a CPAP machine and recording the sound of me breathing on it.  I used an application on my phone to do this (Audio Recording, Google Play Store) and then uploaded it to Google Drive, downloaded it to my computer and imported it into Audacity to edit it further.  For this clip, I had to edit a bit of background noise out and then amplified the clip by 10 decibels as it was very quiet.  Once the clips were saved to my computer, they were easily uploaded into my Prezi. 

The video was recorded on my cell phone as the webcam in my laptop wasn’t cooperating with me.  Once the video clips were uploaded to Google Drive, I was able to transfer them to my computer and edit them in Windows Movie Maker.  The only editing I attempted was editing the start and stop points of the videos to remove extraneous noise.  The video could be embedded into the Prezi two different ways – either by uploading it to YouTube and embedding it or by embedding the video directly into Prezi.  I elected to embed the video directly into Prezi as I found using the YouTube link interfered with the functionality of the presentation and on some public computers YouTube could potentially be a blocked site which would not allow my video to play at all.

    Hi Kelly,

    Your multimedia assignment is highly professional and looks amazing. I learned a ton about a topic I don’t know much about and thoroughly enjoyed the Prezi presentation – again, another tool that I might explore at some point with my students! Your graphics and text are easy to understand and the personalized touch of your video is lovely. I hope to keep your work in mind as I dream up lessons for my students and think it is a great example of ways to use multimedia to support learning.
