How do we teach these things?

For whom does this work best?

So how shall we teach?

“The best way to create interest in a subject is to render it worth knowing, which means to make the knowledge gained usable in one’s thinking beyond the situation in which the learning has occurred.” - Jerome Bruner, 1961

Assimilate? Accommodate? Ignore?

Quantitative tools: Tape Measures, Thermometers and Stop Watches!

Of course, yours will look more like these:

What do we want?

What is the point of math / science education?

• conceptual understanding • fluent skills• problem solving orientation• positive dispositions

What do we want?

We want people who can and will use mathematics and science effectively as tools in their efforts to make sense of the world.

What do we want?

We want people who are equipped and inclined to wonder.
