Use headphones and face away from any distractions that may remain
Understand that there is value in the video and your job is to find it
As you begin, check yourself: Are you fully engaged?
If not, identify and remove obstacles.
Take notes
Take notes, even notes you may throw away.
Keep in mind that notes taken digitally usually allow for keyword searches
Writing down keywords, concepts, and drawing shapes, diagrams like flowcharts, and even doodling can help you maintain focus and retain information.
Writing with a pencil, pen, or stylus may be more beneficial than typing.
Be mindful of definitions, theorems, and vocabulary that may be valuable additions to your "official" note cards
Check your own understanding
Pause, rewind, and seek clarification as often as needed.
Know your resources for clarification:
Google
Peers
Your notes
WolframAlpha
Teachers
If the video provides checks for understanding (like when Sal Khan recommends that you pause a video and work it out on your own or EDpuzzle provides questions), carefully consider and complete the item. Don’t rush.
Let the check for understanding dictate whether you are ready to move on.
If you struggle, rewind, re-watch, seek clarification before moving on.
Know that math is sequential. Most topics are based upon previous material, so it is extra important to understand before moving on.
Not doing so sets yourself up for added frustration and failure in subsequent content.
Wrapping up
Consider watching all or some of the video through once more
Consider earmarking the video to re-watch before the upcoming assessment
