Include specific things you have learned about anthropology, such as the theoretical biological origins of humans or about religions around the world.
Discuss ideas or theories that you had difficulty understanding or mastering. This can give your teacher a better idea of how to help you and other students with the same problems in the class.
Talk about how your perception of the cultural and biological development of human beings has changed as a result of the course. You might express an appreciation of the new insights into world cultures you have developed from the course.
Keep your letter about one page in length. Follow the specific guidelines your teacher gives you for writing the letter. She may ask to you to discuss your ideas on specific topics covered in class or talk about how you feel you did on certain assignments. This would be the case if you were writing a cover letter for a portfolio of assignments for the class. One purpose behind reflective letters is to give students a voice in their assessment in a class. (See Reference 1.) So take the assignment seriously, and connect what you have learned or what you feel you did not learn to the topics covered in your anthropology class.
