Effective teachers I’ve worked with—including me after a couple years (and DEFINITELY excluding me before that!!)—have understood that students learn more when they are reading or writing or doing math than when we are reading or writing or doing math. Provided, that is, we are right there beside them to assess and assist them (and/or facilitate assistance through other resources including each other). And since we can’t be beside students when they’re doing homework, class time must involve less whole-group instruction, and more practice.
