Summary: Interactive lectures include lecture material interspersed with short activities that call upon students to review or develop their knowledge of the lecture topic. This module describes some of the benefits of using interactive lectures. Descriptions and examples of selected interactive lecture strategies are also given.
Interactive lectures can increase student engagement with course material and facilitate learning. In traditional lectures, the majority of class time is devoted to the instructor’s delivery of information. During interactive lectures, the instructor interrupts the lecture to allow time for short activities. These activities can take on many forms as discussed later, but they are important in that they allow students to use material learned in class and contribute to their own learning.
During lecture breaks, the instructor poses a question or problem that promotes students to actively work with the concepts learned in class. Because learners tend to retain information based on their involvement in the learning process, transforming students from passive receivers of information into active users of information leads to increases in student retention of material.
The idea of incorporating activities within lecture time is often met with the criticism that it wastes time that could be used to cover additional course material. However, sustained lectures that exceed the typical attention span of 10-20 minutes do not ensure that the material is actually reaching students. In fact, students record in their notes a greater percentage of material from short lecture segments than they do from longer lectures. Many of the activities described below take only a few minutes to implement, but still provide important learning opportunities for students.
Another benefit of using activities within lectures is that it can create a feedback loop for instructors to get information about student learning earlier than the exam or major assignment date. Seeing students struggle with an activity can be the stimulus for the instructor to review important concepts related to that activity.
Any activity in which students work individually, in pairs, or as teams to answer questions or infer information about class material could be implemented in an interactive lecture. A number of interactive lecture strategies have been developed; some are listed below with short descriptions. For additional ideas to help develop your activities, see the resources listed at the end.
While discussion is best suited for small groups, it can also be effective in large classes separated into groups of students. Another way to use discussion in large groups is to divide the room into quadrants and ask for answers from each quadrant. This prevents receiving answers from only the eager students in the front row. Topics that have more than one correct answer are essential to promote involvement of all group members. Example: Ask students to compare or relate topics from class to events in their own lives.
Students are broken into small groups that each work on a different aspect of the same problem, question, or issue. At the conclusion of small group discussions, the class rejoins for synthesis of the results and discussion of the problem as a whole. Example: Assign groups to act as lobbyists acting in behalf of individuals that would be affected by a new piece of legislation. Give each group time to formulate their arguments and then have the group rejoin to modify the legislation so that it is approved by all parties.
Pause the lecture and ask for questions from the class. Rephrasing the question if necessary, encourage other students to provide the answer. Example: After receiving a question, write it on the board and ask the class, “What information would we need to know to answer that question?”
Students vote for answers to multiple-choice questions. This gives the instructor an opportunity to examine student knowledge before proceeding. This strategy can be facilitated by the use of audience response systems that collect student responses using handheld devices and automatically tally results. Example: Quiz students over new lecture material or review important concepts.
Assign a question or problem and have students work individually to write down their answer. The time spent working alone is important for students to develop their own answers. Then, have students pair with a neighbor to discuss answers. Depending on the type of prompt, students may draw comparisons between the two answers, provide support for their answer, or rationalize differences in their solutions. After allowing students to discuss with each other, call on a few pairs to share their answers with the class. Example: Have students describe and interpret information displayed on a graph.
Participatory demonstrations could involve students acting out a process or making predictions about a process or action occurring in front of them. Example: Students act as the components of a biochemical pathway including mimicking misfunctions of pathway components.
Have students write for one minute about a topic selected by the instructor. Students turn in their writing, thereby helping the instructor to evaluate depth of student knowledge about the assigned topic.
This differs from the “One Minute Paper” in that after writing, students often engage in discussion about the topic. The “Question of the Day” should be assigned during each class or at least once each week and must relate to important course concepts. To keep student motivation high, note at the beginning of the course that these questions serve as a guide for studying.
At the conclusion of a lecture or lecture section, have students identify the most important topic of the lecture by writing it on a piece of paper and handing it in. After the lecture, compare their perception of the key idea to your learning objective. Do they match? This is readily combined with the next strategy, “Muddiest Point.”
This is similar to “Key Point” with the difference being that you ask students to identify the most confusing portion of the lecture. This strategy is an exemplary method to assess student learning in advance of exams or assignments. Students may have questions that require review or questions that anticipate planned lecture topics. Reserve time at the beginning of the next lecture to review important concepts and provide handouts or sources of information for topics that you won’t cover. Take care to address student questions about or confusion with topics so that they also value the activity.
