What One Resource Would You Refer to for Teaching and Learning?

I was asked this question, in so many words, by a guest touring my school today. My response was, "Uhh, well, uhmm...". I obviously didn't have an immediate answer. There are too many great resources out there to make an easy selection.

I threw this question out on Twitter.

I was asked today what professional resource I would refer to that would support best practices in the classroom. What would you have said?

As you can see, there were a wide variety of responses. If this were an election, Twitter would be the winner. Several online resources were also mentioned. I was a little surprised that more actual books were not suggested. For me, I referenced Visible Learning by Dr. John Hattie (Routledge, 2009). What's great about education is that learning is complex enough to allow for a variety of responses with this type of inquiry.

So what is your go-to resource for teaching and learning? Please share in the comments.
