问题     66)In a telephone survey of more than 2, 000 adults, 21% said they believed the sun revolved(旋转)around the earth. An additional 7% did not know which revolved around which. 67)I have no doubt that virtually all of these people were taught in school that the earth revolves around the sun; they may even have written it at test. 68)But they never altered their incorrect mental models of planetary(行星的)motion because their everyday observations didn’t support what their teachers told them; People see the sun moving across the sky as morning turns to night, and the earth seems stationary(静止的)while that is happening.
    Students can learn the right answers by heart in class,and yet never combined them with their working models of the world. 69)The objectively correct answer the professor accepts and the students’ personal understanding of the world can exist side by side, each unaffected by the other.
    70)Outside of class, the student continues to use the personal model because it has always worked well in that circumstance. Unless professors address specific errors in students’personal models of the world, students are not likely to replace them with the correct one.
