Episode 250

In this episode, we’re joined by Margaret McKeown, a leading researcher in vocabulary and language development, to explore what effective vocabulary instruction really looks like in practice.

Margaret helps us unpack common misconceptions about vocabulary teaching, including the pressure to ensure students “master” every word and the belief that vocabulary instruction must always be formal and pre-planned. She explains the power of informal instruction words “running through the classroom” and why repeated exposure over time supports deep word learning.

We also dive into:

• What learning words in context actually means (and what it doesn’t)
• How to think about vocabulary tiers without treating them like a rulebook
• When vocabulary should be taught (before, during, or after reading)
• The connection between vocabulary knowledge and comprehension
• Better ways to assess vocabulary beyond traditional tests

Margaret reminds us that vocabulary learning is more like climbing a ladder than crossing a finish line. Not every word requires deep instruction, but thoughtful, strategic choices can make a meaningful impact on comprehension.

If vocabulary instruction has ever felt overwhelming, this conversation offers clarity, reassurance, and practical insight for making it manageable and effective.
