Don't "over- ICe your T" ( you'll dilute it)

That was supposed to be a pun - if you put too much ice into your tea - you will dilute it; and the tea will lose its essence.
I've begun going out into the field - and this is one of the problems I've been encountering:
teachers are making extravagant PowerPoint Presentations; or finding exciting (and long!) YouTubes....or other interesting sites...but in all this creativity - and I am definitely for creativity - teachers are losing the essence of their lesson objectives.
The essence of an English lesson is English.
It's simple.
Ask yourself:
Does the ICT I chose promote language acquisiton?
Does it help practice the productive side of language - speaking or writing (communication)?
Is what I'm doing worth the effort put into preparing it?
Is the language in the chosen ICT appropriate to my audience - and if not - have I taken the right steps to enable this application to be useful?
