Can you help me with practice question? I do not fully understand the material and am using this to study. Can you define the terms and all of the materials so I can fully learn?

Two recent methods of education reform are voucher programs and charter schools.

a. Briefly describe how these two programs work, highlighting any similarities and differences.

b. Evidence on voucher programs generally show them being much more effective in foreign countries than they are in the U.S. Discuss potential explanations for this finding.

c. Many studies using lottery assignments have shown students winning the lotteries, and getting into charter schools, perform better on standardized tests, especially in Boston. Discuss any reasons why we should be cautious when extrapolating these results to claim that charter schools are more effective than standard public schools.
