Chapter 11 ~ Extra Credit: Screencasting

Starting Jan 2020:

To earn up to 12 points of extra credit as well as help future students, record a screen-cast (in your native language) of you teaching one of the lessons in this textbook.

Students who find that they are coordinated enough to talk and compute at the same time (dare I say talented enough) should put the skill of screen-casting on their résumés!

Teach a lesson.

Print these instructions.

The following procedure has many steps, which are perhaps easier to follow when you print and check them off as you go. Hide/close + the previous section to avoid printing too many pages.

11.1. Choose a lesson to teach.

Which lesson was easiest for you? Or which one did you struggle with but managed anyway? Think about technical skills you learned during the course and pick one set of blue, numbered procedural steps from chapters 1 through 10 to record. Pick a skill that does not already have a sceencast for your platform. Or pick one of those skills to cast in your native language (not English).

The recording of a computer screen while following procedures is called a screen-cast, the result of which is a video with sound that can be shared via YouTube or embedded in web pages and email messages. Most platforms have some form of built-in screen capturing function, but other applications make this task easier and provide trimming, cropping, labeling, and various output options.

If your resulting screen-cast is well produced, it will be added to this textbook (with your permission).

  1. Once you pick the lesson to teach, set up your screen so that only the lesson instructions and your resulting file are visible on the screen. For example:
    Set up the orientation of tabs in two windows.
  2. Zoom in with Ctrl+ or + so that menus, functions, and panes are larger.
  3. Read the steps to practice (but don't read it for your final recording). Do you find it difficult to read and do the tasks at the same time, or do you find it simple enough?
  4. Practice doing the procedure a few times to get comfortable.

11.2 Set up screen-casting software.

  1. Launch Chrome browser.
  2. Navigate to Screencastify. If prompted to purchase, go to the Pricing page to choose the $0 free option.
    Other options include:
    • MacOS: Screenshot app. Learn more...
    • Windows: Use the search bar to locate the Game bar (Win-G). Choose Game capturing. Learn more...
  3. Click the Add to Chrome button. Allow all permissions.
    Screencastify permissions Screencastify permissions
  4. Click the Screencastify arrow Screencastify next to the address bar in the Chrome browser Extension bar.
  5. Login with your OSU Google account so you can save the file on your Google Drive.
  6. View tutorials to see an example and learn how to proceed. Start with this introduction:
    Captioned.
  7. Read the 24 Tips for Creating High Quality Screencasts article to ensure you are ready.
  8. The four most important qualities of your recording are:
    • They follow this textbook's instructions. The goal is to supplement one set of blue-headlined textbook steps.
    • Sufficient volume and tone: a quiet and/or gravely voice is irritating. Speak clearly.
    • Sufficient size: all elements you point to on the screen must be legible. Use the 1920x1080 or smaller screen size. Don't use an entire Retina display screen; it is too big.
    • Sufficient time: Keep the lesson short...under 1 minute is preferable and no more than 2 minutes.

11.3. Cast the lesson.

After you have practiced the skill while speaking the instructions outloud, record it:

  1. Click the Screencastify Screencastify Chrome Extension next to the address bar.
  2. The default settings are fine. Do not turn on the webcam.
    Screencastify options
    If you have an external microphone that works better than your computer's built-in microphone, choose it from the list of microphone options.
  3. If the microphone doesn't work, try plugging in a set of earphones.
  4. Click the Record button and state your name and the name of the lesson.
  5. State which platform and application you are using for this demonstration.
  6. Show how to do each step with your mouse and keyboard while you describe it with your voice. Do not read the textbook...tell viewers what to do in your own words.
  7. Feel free to use the Zoom and other screen tools, as noted in the tutorials.
  8. Mention recommendations as needed (as long as they do not stray from the existing instructions).
  9. Pause and stop the recording as needed to complete the cast.
  10. Save the recording to your OSU Google Drive.

11.4. Review your work.

  1. Listen to your recording to confirm it captured all the necessary steps, was loud and clear, and each menu item you selected was visible.
  2. Redo the cast as often as needed to meet these requirements noted in the Criteria at the bottom of this chapter.
  3. Trim or crop the recording to improve legibility, if necessary.
    Screencastify editing options
  4. Rename the screen-cast file with the step number, step title, your last name, and your first name, like this: 1.2-learn-about-canvas-menu-vanlonden-pam. Use lowercase letters and hyphens instead of uppercase and spaces (an HTML standard for file names).
  5. Save the file to your Google Drive.

11.5. Share and submit the screen-cast.

  1. Select the screen-cast from your list of casts, or click on the single cast you want to share with the instructor.
  2. Click the icon on the toolbar.
  3. Share the file with your OSU YouTube account.
    Screencastify  sharing to YouTube
  4. Click the Get Link link to copy the YouTube sharing URL.
  5. Submit the sharing URL in the Chapter 11 extra credit Assignment or Commenting box.
  6. Note whether you grant permission or not to add it to the textbook.

11.6 Edit the automatic captioning.

  1. Login to your OSU Youtube account.
  2. Locate the screencast you uploaded from Screencastify.
  3. Click the Close Captioning icon.
  4. Edit the English subtitles/captioning that was automatically added to improve the English:
    • Spelling.
    • Capitalization.
    • Punctuation.
    Save the work.

Back up to multiple sources

Earlier, you saved a copy of your work with a new name. Now, copy that backup to a different location, such as:

  1. Cloud drive such as Google Drive, Microsoft OneDrive, or Apple iCloud.
  2. A USB stick drive.
  3. Zip archive file.
  4. Turn on automatic backups.
    • Windows 10
      Learn to use the Windows File History feature to backup files to a new location.
    • MacOS
      Learn to use Time Machine for backup up automatically to external hard drive devices.

Because bad things happen to good people and their computers, you must back up every time you work on a project. Losing your work because of a technical glitch and lack of a backup will not provide you with a due date extension; it will only provide you with empathy.

Criteria to meet by the end of chapter 11

By the end of chapter 11, these items must be completed to earn full points:

  1. Cast starts with student's name.
  2. Cast states the number and name of the lesson.
  3. Cast states the platform and software used for the lesson.
  4. Content of the recording correlates with the textbook lesson.
  5. Textbook instructions are on the left one-third of the screen.
  6. Working file is on the right two-thirds of the screen.
  7. Volume of the voice is loud and clear.
  8. Dimensions of the cast are 1920px by 1080px or smaller.
  9. Mouse actions are legible.
  10. Cast does not have wasted space at the beginning or end.
  11. Cast is under 2 minutes.
  12. Automatic subtitles/closed-captioning was edited for proper grammar and puctuation.

If you have questions about how to use any of the required technologies for this lesson or what the following criteria mean, please reread the relevant lessons, view the Zoom recordings, then ask the Instructor via the Canvas Inbox.

Check Canvas Home, Assignments, and Calendar for the most current Due date and time. The Available Until date and time constitutes a grace period, which can be used in an emergency, or if you are ill.
