One of the assigned readings this semester is “How to ask questions the smart way“, which provides important tips on how to utilize the online community efficiently and effectively. This page provides tips on how to watch screencasts the smart way.
This issue is important, because ICS 613 uses a “flipped” pedagogy, in which lectures are not provided face-to-face but rather online through YouTube videos. Two primary benefits of the “flipped” approach are:
- Precious class time can be spent on group work activities where face-to-face interaction is most valuable.
- Screencasts can be viewed by students at the times and places of their choosing. Sections of screencasts can be re-viewed as many times as each student desires.
After several years using this approach, student reaction is generally positive. At the same time, this new format does create certain challenges for efficient and effective learning. Here are some heuristics we’ve discovered for addressing these challenges.
#1: Don’t multi-task
Since you can watch the screencasts at a time and place of your own choosing, it is tempting to watch them while also doing other activities: watching TV, texting, talking to friends, playing online games, reading FaceBook. However, since your goal is not to simply have watched the material, but to have actually learned the material, and since mounting scientific evidence shows that multi-tasking impairs learning ability, it is in your best interest to block all other activities while watching the screencast. Since most screencasts are only 15 – 20 minutes long, this is not a huge imposition.
#2: Take notes
In a traditional classroom, the lecture is ephemeral and thus written notes provides a necessary means to capture the information. (Other mechanisms include recording the lecture on your phone, or even videotaping the lecture with your phone.) When the lecture is already recorded and available at any time as a screencast, it might seem reasonable to not take notes because the material is always accessible online. However, to maximize the efficiency with which you learn the material, you should take notes on the screencast, because note taking stabilizes information for retrieval at a later date.
Put another way, your ultimate goal is to not have to re-watch the lecture every time you need the information, and note-taking helps you achieve that goal more quickly and efficiently. Since you are not multi-tasking, you will have the time and space necessary to take notes on the lecture. Finally, by recording the elapsed time into the lecture associated with the material represented in the note, you can use your notes to later rewatch portions of the material quickly and efficiently as needed. A final, important role of notes is to record questions you have about the material for later discussion, as presented next.
#3: Use the mailing list to ask questions and discuss the material
One of the most significant pedagogical drawbacks associated with the “flipped” classroom is the inability of the instructor and students to engage in real-time, interactive conversation about the material as it is introduced, and the inability of the instructor to modify the presentation in real-time to adapt to student reaction. Screencasts can further inhibit conversation about the material if students conclude that their questions could be resolved simply by re-watching the screencast at some future date. To learn most efficiently, you should record questions you have as you watch the screencast, then post those questions to the discussion group.
#4: Watch in full screen, high definition
Many of the screencasts involve demonstrations of user interface tools or other technologies. You should watch those lectures in full screen mode in the highest resolution possible. That way, you will clearly see all user interface elements and be able to understand the procedures most easily. Watching in full screen mode also prevents you from seeing other windows, thus helping to minimize multi-tasking.
