Learning outcome:

After reviewing the short video, students will be able to outline the major functions of skeletal muscles.

Activity 1 – Video

Watch the YouTube video Skeletal Muscle and write a summary paragraph to describe the major functions of skeletal muscle.

 

Processes

I used Screencast-O-Matic (free version) to record my screencast. Below are the steps I followed:

  1. Download Screencast-O-Matic.
  2. Open Screencast-O-Matic and set it to full screen.
  3. Click the red circle button on the top right corner to lunch Recorder, a frame would appear on the screen. Set the frame size so it captures your whole slide.
  4. Open your PowerPoint presentation slide, make sure the slide is inside the frame.
  5. Click on the Narration button at the lower left corner, select your microphone, wait for the countdown then start doing your voiceover.
  6. You can always stop and delete the recording to start all over again if you are not happy with the quality.
  7. When finish, press done and save it to your folder.
  8. I uploaded the video to Canvas to add some background music to go along with the narration. The free version of Screencast-O-Matic does not allow you to add audio to your slides.

The video incorporated the following readings and theories I learned in this course:

 Captions: Captions describing the content on the screen is available for the students.  Students are also able o play the video repeatedly, pause, and rewind. They are able to note time-stamps for portions they want to review it again.

 Mayer’s Personalization principle: The audio narration of the video is done by a real person and not generated by the machine. Students learn better when the narration is spoken in human voice than a machine voice.

 Mayer’s Signaling Principle: A pointer is used in the video to bring the students’ attention to a specific bullet point. People learn better when cues are added that highlight the main ideas and the organization of presentation

Mayer’s Modality Principle: Deeper learning when words are presented as narration rather than as on screen text.

Generative activity principle: People learn better from a video lecture when they are asked to engage in generative learning activities during learning. Students are asked to write a summary paragraph after watching the video
