Have students prepare individual concept maps on a given reading or idea from the reading to bring to class. Allow students to generate exam possible exam questions from the readings. Be willing to actually edit and use some of these on the exam. Help students form study pairs or groups.
Students can read together, quiz each other on readings and so on.
Have students share their individual concept maps in groups and write a group concept map. Give students a complex question to consider. Have each write on this question for 5-15 minutes. Then discuss in small groups or with the whole class. Divide the material among students or groups of students.
