My comment about this is that this is now the nail in the coffin for traditional teaching (just telling kids stuff)

I made this investigation to look at various circle theorems. However, I made two versions. One that requires much more construction and one that has far less (so it takes less time). Get them both at the link below:

Do you want a reason to look at the distance formula on the coordinate plane? Then look no further

Sadly, there are no longer Toys 'R Us stores, but the context remains. How does a computer know how far away a store is away from you? It's similar to finding distance on a coordinate plane. https://t.co/t0jmdqBNzL pic.twitter.com/5U8gSszzs8

I am rewriting and tightening up all my algebra notes and thoughts into one tome. I think I properly tightened up making sense of the AREA MODEL for arithmetic… pic.twitter.com/eMnp2N3n39

Perfect if you are dealing with your students learning about finding sidelengths with trig ratios.

The thing I like most about this is the fact that it shows that, for the most part, effective teaching has bits of all the researched based ideas in proportions based on you. And those proportions vary from person to person when it comes to what is effective. But regardless I like @Jason_To's even keel treatment of this.

Many pro-direct instruction folks are using a recent article from BNN as evidence against inquiry-based learning, thinking classrooms, etc.

I respect these people as educators who, like me, want what's best for students.

But, let's dig into what this study actually tells us. https://t.co/m9EY14Rbw0

We don't always have to rely on "two negatives make a positive" when subtracting negatives. Here's another way to think about it. pic.twitter.com/FU84rlO4RO

Even if you didn't make a slow reveal graph out of this, I think it would still be a good discussion with students about how long they take their showers.
