By asking both kinds of questions, the teacher scaffolds the children’s learning, or creates a zone of proximal development, which we described in Chapter 2 as part of Vygotsky’s theory of learning. Note that this zone has two important features, both of which contribute to children’s thinking. One is that it stimulates students’ thinking (by asking them questions), and the other is that it creates a supportive and caring atmosphere (by honoring their personal experiences with real questions). The resulting mix of warmth and challenge can be especially motivating (Goldstein, 1999).
