 So if we're measuring the competency of just knowledge, you can go ahead and use multiple choice tests, dates, facts, formulas, anything Google-able, you can actually do that on a multiple choice test. But if you want to get to something higher, if you want to try to measure skills or attitudes, you need to use a different set of tools. The tools that you measure attitudes can also be used to measure knowledge and skills. And so the big idea here is if we really do value knowledge skills and attitudes, maybe our tools need to change within evaluation.
