Your assignment asks you to find "scholarly videos from a credible source." To determine whether or not you can use a video you've found, consider:
Click on the videos tab to limit your results to videos.
Then, use the site: search command to limit your search to just 1 website.
|Site:ubc.ca cognition||Searches UBC's entire website for the word cognition|
|site:psych.ubc.ca cognition||Searches only within psych.ubc.ca (UBC's Department of Psychology) for the word cognition|
|site:stanford.edu happiness||Searches Stanford's entire website for the word happiness|
You will need to find the first part of a website's address to use this command. Not sure? Google an education institution to find them first.
These are a just a few - you should feel free to explore videos from other Universities as well!
Aman suggests TED. You can also check to see if you have access to the sites listed here.
Or, search the CapU Library using the Discovery search, then limit your search to Videos using the filters on the left-hand side of your results screen.
