the student experience in schools around the world? How do we know?

Read the Prologue (“The Mystery”) and Appendix II (“AFS Student Experience Survey”) from The Smartest Kids in the World. Then, respond to the following questions:
1) Ripley states that the chart on page 3 “blew her mind.” Why does she state this? And, does it blow your mind, too? Explain briefly why or why not. [2 paragraphs]
2) In the Appendix II, Ripley enumerates the findings of their student surveys, focusing on five areas of broadest agreement. Choose one of these five that you find the most surprising – and another one that you find the least surprising; explain why for each. [4 paragraphs]
3) What additional questions would you have added to this survey? Please briefly explain why you would add them. [At least two questions with a short rationale for each]
