Cathy Moore runs a well-received blog on elearning. In this post she offers both tips (nothing too revelatory) & gotchas (where she has decided NOT to use certain tools, eg public chat, 'meaningless' polls & breakout rooms). She discusses webinars in general, not Collaborate specifically.

7 checklists to consider when building or before releasing a elearning course. Some questions are bleeding obvious, but others are quite deep.

A great, simple website that lets you trim a YouTube video to just the part you want. Simply drag the entry & exit sliders to the relevant part of the video ... & press Chop It. It then gives it a new URL &/or Embed Code. Great for plucking out pertinent snippets from a long lecture.

Some interesting options for online presentations. (One of them, of course, is Prezi.)

Listing with a brief description of smart phone use in the classroom. Some well known; some lesser known ideas.

Most of the tips are relevant to higher ed, and each contains a decent paragraph description.

Nicely breaks up elearning interactivity into 4 levels - from Level 1: Passive (no interaction) up to Level 4: Simulation and game-based learning. Provdies examples of activites in each level.

Neat visual summary of how teachers are using social media. Comprises mainly one long graphic.

Discusses 'learning measurement'. It includes a Course Review Template aimed at measuring how performance focussed the course is. Also, his link to a previous article (The Five failures) is worth a read.
