Microlectures

You may have heard some buzz recently about microlectures or mini-lectures. Here’s The Innovative Instructor’s scoop on the topic.

Microlectures are just what they sound like – short, focused discourses on specific topics. If you’ve ever watched a TED talk, you’ve experienced a microlecture. The classic TED talk is 18 minutes or shorter, and the speaker concentrates on developing a single big idea.  Another example of the microlecture can be found in the Khan Academy model. The Khan Academy website boasts a library of videos covering “…K-12 math, science topics such as biology, chemistry, and physics, and …humanities with playlists on finance and history. Each video is a digestible chunk, approximately 10 minutes long, and especially purposed for viewing on the computer.”

What does this have to do with you and your teaching approach? Research has shown that a student’s attention span during lectures decreases after fifteen minutes [Wankat, P., The Effective Efficient Professor: Teaching, Scholarship and Service, Allyn and Bacon: Boston, MA, 2002]. Once you lecture past that time, students retain significantly less information. [Hartley, J., and Davies, I., “Note Taking: A Critical Review,” Programmed Learning and Educational Technology, 1978, Vol. 15, pp. 207–224.] Hartley and Davies suggested that breaking up a lecture into smaller segments could help keep students engaged.

One way to integrate microlectures into your face-to-face teaching is to intersperse short periods of lecturing  with active learning activities. These exercises will reinforce the material you’ve just presented.

Even if you have a large enrollment for your course, it is possible to implement active learning strategies. A quick method is “Pair-Share.” After presenting in a microlecture format, have your students pair off and discuss a question you pose to test their comprehension of the material just covered. Eric Mazur, Professor of Physics and Applied Physics, School of Engineering and Applied Sciences, Harvard University, has written and presented (see his talk, Confessions of a Converted Lecturer, from the JHU Gateway Sciences Initiative 2012 Symposium on Teaching Excellence in the Sciences) on using active learning, and pair-share exercises, in large courses.

The Educause Learning Initiative recently published a short tip sheet on microlectures that are recorded for students to use outside of the classroom: 7 Things You Should Know about Microlectures.  This two page PDF document addresses recording microlectures for hybrid or “flipped” class settings (where the recorded lecture is viewed by students outside of regular class time), but contains advice that will be useful in fully face-to-face learning environments as well.

If you are interested in learning more about active learning strategies and how you can integrate these into your teaching, perhaps in conjunction with microlectures, you can get a jump start by reading the article, Active Learning: An Introduction [Felder, R.M. and Brent, R., 2009, ASQ Higher Education Brief, 2(4), 1-5].  This is an introduction to active learning that includes frequently asked questions about what you can do and what you can get your students to do.

What’s New with Clickers?

There’s a new clicker on the quad this fall.  Clicker is the popular term for the devices used for in-class voting systems. The Homewood campus is now using the i>Clicker Classroom Response System; students can use the same clicker device in multiple courses. One of the benefits of the i>Clicker system is that it is integrated with the Blackboard course management system.

Faculty need a computer, either their own laptop or the podium computer in a smart classroom, to use clickers during class. Students simply purchase and register an i>Clicker voting unit. For the Krieger School of Arts & Sciences and the Whiting School of Engineering, the Center for Educational Resources (CER) will provide the i>Clicker software and an RF receiver if needed. Interested faculty can borrow a loaner i>Clicker system to try out in a class up to 50 students. For other JHU schools, contact your divisional instructional support center for information.

In-class voting technologies were first piloted in classes on the Homewood campus in spring 2003. Since then in-class voting has become ubiquitous in large enrollment classes at Homewood; over 2500 students per semester use the system. Clickers are used in courses such as biology, chemistry, civil engineering, earth and planetary sciences, history of science and technology, materials science, physics, and psychological and brain sciences.

Clickers allow faculty to engage students quickly and easily. They enable faculty to:

  • Give and grade objective pop quizzes on readings or other assignments
  • Conduct in-class polls in real time
  • Stimulate class discussion by posing subjective questions, using either ad-hoc or previously developed questions
  • Manage, record and run reports on all aspects of students’ performance using the system
  • Take attendance

In a typical example, an instructor poses a question, often multiple-choice, to the class. Then students think about the question and submit their responses using their handheld wireless transmitters (clickers). Responses are beamed to a receiver plugged into the instructor’s computer. Software on the computer processes the information quickly and displays a bar chart showing the distribution of student responses. Instructors can then use these responses to decide how to proceed in the class.

Opinions vary on whether or not to use clickers for grading class attendance. Some instructors simply use clicker votes to count as participation points, just as they might grade students in discussions. For instructors who would like to monitor attendance over time, clickers can record attendance.

Instructors have found that using clickers has dramatically increased attendance in class, enhanced just-in-time teaching capabilities, increased classroom participation and simplified the deployment and grading of quizzes and exams. Data collected over several years in several courses show a direct correlation between clicker participation and final grades. Clickers are generally considered to be one of the foundations of an active learning classroom.

Faculty who are interested in learning more about the in-class voting system should
contact Brian Cole (bcole@jhu.edu, 410-516-5418) or drop in to the Center for Educational Resources on Q Level in the Milton S.Eisenhower Library.
