Student-led discussion groups in large lecture courses prepare students to take part in the daily conversations that will be part of their future lives, first as students in advanced courses and, later, as physicians, researchers, engineers, lawyers, managers, or citizens. After graduation, students will be expected to participate in meetings and discussions, contributing insights and conclusions based on personal experience and scientific knowledge they learned here. In advanced classes, students will engage in discussions of the material presented both in class and in peer study groups and project teams. When they propose solutions to problems, they will be expected to explain processes and technical concepts for non-specialists as well as other professionals. And in many interdisciplinary situations, they will need to reconcile different perspectives and definitions in order to reach a consensus about how to approach a complex problem.
In student-led discussions, students participate positively in group discussions, leading and managing discussions toward productive conclusions, and reaching consensus on topics. Because the discussions are student led, group leaders refrain from participating in the discussion and instead observe the discussion to evaluate the accuracy and effectiveness of the presentation, the quality of the discussion, and the process of discussion. A student’s grade for the day will reflect the number and quality of contributions made and the thoroughness with which the Preparation Form was completed before class.
We all learn by acquiring information from our environment (through visual and auditory systems). We map the information in the brain in a unique and personal way that reflects how we relate to it. We use these mental maps to structure and code knowledge, store it, decode it, and recall it. As students learn about a topic, their minds creatively construct unique maps that place the new information in the context of their existing maps. Students will have myriad of unique experiences, learning styles, perceptions of their needs, and even perceptions of shared experiences. Although two students may read the same passage from a textbook, they will come to the discussion with different mental maps of the information. For example, a student who grew up near a beach may relate a biological process to the movement of water in the tides. Another student who worked in a laboratory may relate a process to a similar process in his/her research area. In the discussion session, students will bring their own mental maps to the group. By sharing understandings of the material and questions about it, the entire group will come to a consensus on the topic—a group mental map—that will be richer than the mental map of any individual. The multiple connections will enable participants to solve problems and apply the concepts in multiple ways, increasing their mastery of their knowledge. Students will then apply their extended knowledge on exam questions based on the discussion topics.
Each discussion group typically consists of 12–14 students and one group leader. In Introductory Biology at Rice University, the discussion groups meet on pre-determined dates during the semester. Meetings should occur in locations that foster face-to-face communication (not rows of chairs facing a lecturer’s podium).
During each discussion session, students discuss two pre-assigned topics. Topics are assigned in class and by email or posting on the course website. Students have one week to research the topics and complete a Preparation Form for each topic. Completed Preparation Forms will be brought to each session and handed in to the group leader at the end of the session.
Before the session begins, the group leader prepares a list showing who will fill each role. Only at the beginning of the session, the group leader announces the roles for particular students. To motivate students to prepare, group roles are kept secret until the session begins. The roles are as follows:
- The presenter gives a short presentation (under six minutes) on one of the assigned topics, using his/her Preparation Form as notes. A legal pad or whiteboard will be available if the presenter wishes to draw a visual aid for the rest of the group.
- The discussion leader moderates the discussion. He/she keeps the discussion going, turns to the group for questions or comments, notices who wishes to speak, and ensures that everyone has a chance to contribute to the discussion. If the group seems confused or becomes deadlocked in disagreement, the discussion leader should ask the group leader for clarification.
- The writer takes notes during the presentation. After the presentation, the writer prepares a short (1/2- to 1-page) written summary of the topic. The writer also lists any questions that were unanswered during the discussion; these questions will be answered by the course instructors on the course website. The course instructor or some designated person will collect the summary at a specified time by following the discussion. The best written summaries on each topic will be posted on-line for students to use in preparing for exams.
- The summarizer/synthesizer pulls together the most important points made during the discussion and presents the group these points to conclude the discussion.
Each of the two topics is discussed for approximately 20 minutes:
- 5–6 minutes for presentation
- 10 minutes for discussion
- 3 minutes for summary/synthesis.
When discussion of a topic concludes, the group leader then comments on the group’s discussion for 1–2 minutes.
