Ms Killian and Her Fourth Graders Have Been Growing Sunflowers

Ms. Killian and her fourth graders have been growing sunflowers under various conditions-they have grown sunflowers in different kinds of soil,with different amounts of water,and in varying degrees of sunlight. Below are four statements that Ms. Killian makes related to the sunflowers. Which one is most consistent with the idea of a cognitive apprenticeship?

A) "Who can tell me what photosynthesis is?"
B) "How many of you have grown sunflowers at home? How many of you have moms or dads who are gardeners?"
C) "This sunflower is taller than that sunflower over there. Let's consider what the growing conditions for the two flowers have been and try to figure out what might have led to the difference we see now."
D) "Elaine,please give each plant the same amount of water today that you gave it yesterday. Also,be sure that you keep each plant in the same location,so that the amount of sunlight it gets stays the same."
