Not Right For WatchKnowLearn
WatchKnowLearn ratings are intentionally harsher than what you might find on YouTube, for example. Most of our videos have been imported by people who want to use them with kids, not by the creators of the videos. We take a hard-nosed attitude toward quality. Four and five stars should be reserved for really excellent quality. Three stars isn't bad. Two is often watchable and shouldn't be ruled out.

  • 5 stars = Exemplary.
    Unusually helpful and well produced. Do not overuse this, please; it is not the standard rating for decent work, as it is elsewhere.
  • 4 stars = Very Good.
    Very helpful but not among the very best; adequately produced, at least.
  • 3 stars = Usable.
    Reasonably helpful, perhaps a bit amateurish in production or has some other problem; there is nothing wrong with a 3-star rating for amateur work!
  • 2 stars = Some Merit.
    Minimally helpful; not completely worthless or inappropriate; you can see how it might be useful to some people.
  • 1 star = Not Right for WatchKnowLearn.
    Not at all helpful, not educational, poorest quality, etc.; you can't see it being useful to anyone.

From YouTube (Approved: Mrs Jefferies), produced by CBS
 
Scientists estimate that there are currently 50,000 invasive plant and animal species in America - and that number's sure to rise. Mark Strassmann reports in this CBS news special.  Some animals discussed are Asian Silver Carp, African Killer Honey Bees, a South American Rodent, and the Burmese Python.  One plant discussed includes Kudzu, also insects, mussels, and giant slugs.  The video talks about the pros and cons of bringing animals and plants from other parts of the world into America, including the expensive monetary concerns involved with control of some invasive species.

  • Unless changed, the Finder is the person who uploaded the video to WatchKnowLearn.
  • The Finder is allowed to "lock" information about the Owner and Producer (so other accounts cannot edit this information). The Finder field should match the Owner field when a video is entered in a contest.
  • As owner of a video, you can have finder rights transferred to you.
Simply click "Request Finder Rights" and an e-mail will be sent to the current Finder of the video. The Finder may then transfer rights to you. If he or she does not, bear in mind that an Administrator will see the refusal of your request and will be able to review it.
