Metrics that confuse me
Recently I was involved in a conversation where the number of faculty and students that used a specific tool came up.
It was noted that a fairly low percentage of both used, campus wide.
Everyone in the room nodded wisely (I think I even pulled on my beard in a thoughtful way) and we all agreed (or almost all of us) that this was an issue (or a problem).
Then, as often happens with me, I wondered off and had a proper think on this.
In my mind educational theory, technology and blended learning are all like a buffet.
One takes what one likes, what’s appropriate for the time of day or your dietary restrictions and one moves on.
The goal of the buffet is that everyone gets fed with something that they like and works for them, not that everyone eats each and every dish.
Shouldn’t learning technologies be the same?

Another metaphor would be the toolbox: we learn to use as many tools as our job may need, carry most tools around us as we do our job, and fish out the tool we need at the appropriate time/context. And it’s only natural that some tools are used once a month (since the job didn’t demand its use).
That’s a good metaphor as well. I guess I was hungry when I wrote this.
