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 hippocampus.org (Approved: helpingnorth), produced by University of California
 
The origins of slavery can be traced back much further than the eighteenth- and nineteenth-century plantations in the southern United States. By the time the English had begun to settle permanent colonies in North America, the Spanish and Portuguese had developed a model of slavery to provide labor for commercial agriculture. This model was critical for the development of slavery in Anglo-America.
The development of the slave trade began with the Portuguese exploration of West Africa, primarily from Senegal to Angola, in the fifteenth century. With funding from Prince Henry, a patron of sciences who devoted his life to sponsoring innovation, the Portuguese sent expeditions to West Africa in hopes of finding gold and, later, an eastern water passage to facilitate trade with Asia. (Video is  of high quality with slides and narration.)

  • 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.
