This is an activity I do with my high school students during a unit on the Civil Rights Movement. Included in this resource is a general lesson plan, Structured Academic Controversy and Coming to a Consensus handouts, handouts with 10 biographies of different female activists from the Civil Rights Movement. Also included is a chart to organize info. about the activists if you would prefer to structure the activity as a scaffolding activity instead.
To start the activity, I divide the students into groups of 4 and then each group is divided into 2 teams. Each group gets copies of a handout with short biographies of two female activists. One team studies the first activist and the other team studies the second activist. After a period of time passes, each team in the group teaches the other team about their activist so that everyone in the group learns about both of the female activists.
Next, both "teams" come together with the entire group of 4 students to come to a consensus about which of the 2 female activists they studied was more effective in making change. This involves a mini debate among the group members in which they will have to use evidence from the sources to convince the other members of the group to agree with one of the two female activists.
