I organize most of the material I collect into subject-specific "Scoops" (a kind of blogging tool) When I have about ten new items I mail these to the relevant teachers in the form of a newsletter. You can check out all my Scoops here
I would be happy to add you to the mailing list for any one of these. You can mail me at
avanzyl@phs.org.za
I try to focus on items I believe will make the teaching process more interesting and enjoyable and relevant! There is no cost involved and I can easily unsubscribe you if you are no longer interested. I send out about three subject-specific newsletters per month.
Happy teaching, Andrew
