Most of us are researchers AND teachers. As teachers or instructors we constantly create current and state-of-the-art instructional materials for our students to keep pace with the development within our subjects. There many Websites that aim at supporting teachers of all grades and educational levels by letting them share such materials as slideshows, videos, animations, posters, collections of links, and quizzes.
It usually takes less time to adapt existing materials to own needs than to create those materials from scratch; therefore, it would be useful to have a collection of items (lectures, rubrics, test banks, etc.) at hand from which one can choose the best candidate for adaptation.
We should use a topic for this kind of material, e.g. 'Instructional material' (added on Jan. 18, 2016: the better term 'Open Educational Resources' already exists as a topic; let's take this term instead).
