Thank you to Alice Ayel for getting me to look at slideshare groups. Alice's group, teaching-languages, is definitely worth joining as it already has many good slideshows designed to teach different French topics and items of grammar.
I also subscribe to E T Albert's web 2.0 tools for effective teaching but there may be a lot more to discover on slideshare groups...
Following in Alice's steps, I decided to upload my "preaching to the converted" presentation (IOW conference Show and Tell) and a "Blogging for all" presentation I did for an introduction to blogging during our termly joint Faculty meeting with Humanities.
I also tried to blog these direct from slideshare but it sent them to my student blog!!
