 The lecture is disappearing. Pictured here is a surgeon's lecture (ca.1900)
A paradigm shift, according to Thomas Kuhn, is a change in the basic assumptions or ruling paradigms within a scientific discourse. At first, anomalies begin to appear and accumulate until a crisis occurs and the ideas of old begin collapsing under the weight of unresolvable contradictions. I want to argue that a kind of paradigm shift is currently underway in regards to the usual pedagogies employed in college courses. Fissures have begun to appear in the longstanding pedagogical substructure, but in contrast to Kuhn's model for scientific revolutions, a pedagogical revolution is being hastened, not by anomalous observations, but by the emergence of online education.
Still this revolutionary transformation eludes many of those who work in higher education. After all, the experience of students who take online classes appears to be similar to that of their 20th century counterparts. Students must still read, they are still tested, and they still encounter course material that has been organized by an instructor. But the lecture, that standard fixture of higher education since at least the 12th century, is quietly slipping into history, and its unintended demise is the result of the suite of new online technological capabilities coupled with a growing demand for flexible course schedules. The Life of the Lecture Before elaborating on my claim that the lecture is in decline, and before I propose what to do about it, I want to be clear that I think lectures can be incredibly useful features of any course. While the notion of a lecture often calls to mind a static presentation, for me lectures are quintessentially dynamic, live gatherings of students and instructors that take place at particular times and in particular places. Because they are live gatherings, they can facilitate student cooperation, and at the very least, they provide students with a sense that they are a part of something bigger than themselves. While the structure of the lecture promotes a situation where students can openly support and even depend on each other, lectures also provide instructors with the means of pushing back against, say, one student's reductionist views, while paraphrasing another student's insights. And the lecture allows instructors to respond to individual students in real time and in full view of other students, so that each interaction might become a teaching moment for an entire class. Just as laughter and applause are contagious in packed theaters, so too is student engagement, and like any stage performance, the lecture is a format that allows instructors the ability to dynamically react to their live audience and cultivate this contagious engagement. Articles have been written about how lectures are outdated relics that do not account for the cognitive limitations of students, Others have written that lectures are ill-equipped to compete with smart phones, which are far more entertaining. Whether lectures are too cognitively demanding or not entertaining enough depends on how the lecture is structured and what happens at the live gathering. People often forget that lectures are unique among course components in that they allow instructors the ability to react to this infiltration of distracting gadgets. In few places but the live lecture, can instructors effectively monitor and regulate the use of cell phones among students, and only in the lecture can instructors modify their presentations once it becomes apparent that too many of their students are smiling into the LCD displays in their laps.  The end of the college lecture looms
The Death of the Lecture
Online education is hastening the demise of the live lecture. For some time now online course technologies have allowed students to take classes from the comfort of their homes, and crucially, to do course work at times that do not conflict with their other commitments. Attending a class that meets regularly is a fundamentally different experience than logging in to an online class. It is of course possible to replicate the simultaneity associated with live gatherings by arranging a live video conference with students, but by and large, this strategy undermines much of the scheduling flexibility that has been driving the growth of online education in the first place. If students must be at their computers at particular times each week, then they might just as well agree to meet in a physical classroom. It should be noted that the demand for flexible hours is not simply due to clever marketing campaigns from entities like Coursera or the University of Phoenix, but in all likelihood the demand stems from a widespread economic reality: lower paying jobs, longer working hours, and greater debt. Students are coming to need the flexible hours offered by online education because they are filling their schedules with internships and other activities in a struggle to gain qualifications in an increasingly competitive job market, and they are working longer hours in low paying jobs in order to deal with the rising cost of their education.
The Promise of a Video Pedagogy Perhaps more college instructors should follow in the footsteps of Princeton University professor Mitchell Duneier, who turned his back on the MOOC (massive open online course), refusing to support a trend that might lead to state legislators cutting funding to state universities. Perhaps there should be more resistance to online forms of education, but at this juncture, my aim is not to incite a rebellion against online courses or even forestall their development (as if I could!). Instead, I want to conclude by discussing how video can be used to fill the void left by the disappearing lecture, and how it will be an important component in the pedagogies which emerge to address this new online paradigm. When designing online courses, many instructors take a kind of skeuomorphic approach and set about crafting digital duplications of the classes they once taught in physical classrooms. Physical documents can be replaced by electronic documents, so it is easy to fall victim to the idea that lectures can be handled in a similar manner. Examples abound of instructors who have produced digital videos of themselves delivering their lectures, but this approach transforms what was once an interaction between instructors and students—and students with each other—into a unidirectional data dump (see Michael Burawoy, Mitchell Duneier, and Ann Swidler). Few other arrangements than a video of a person standing at the front of a room talking will have as much trouble stirring interest and engagement among students. Digital videos have an important place in online education, but video is capable of so much more than simply recording a person talking. The lecture after all is a live event, so by definition, a recording of it will not suffice anyway. How then should video be used in the online course? How will it fill the void left by the lecture? It only makes sense that instructors who use video capitalize on its unique strengths. In what follows, I conclude by pointing to four key strengths of video, which can be leveraged to facilitate learning among students: 1. Video Can Illustrate Complex and Abstract Ideas It is no mystery that in any field there are particular concepts and theories students typically struggle to understand. Videos can be incredibly useful for providing students with illustrations and suggesting idioms to aid in making sense of otherwise intangible ideas. For example, rather then simply explaining to the camera the Marxist idea of Capitalism's internal contradictions, it is far more engaging and memorable to show a video that combines an explanation of Marxist theory with an illustration that unfolds across the properties of a Monopoly game board.  Hollywood films can promote affective learning
2. Video Helps Visualize Big Data
Sometimes the challenge facing instructors has less to do with explaining abstract concepts and is more about making the findings from big data comprehensible. In many classes, students are bombarded with statistics that often make little sense. Videos can be useful for showing graphs and figures, which place statistics in context by offering comparisons across categories (e.g., race, gender). Videos are particularly useful for contextualizing a number by illustrating how the number has changed over time. Thus rather than simply telling students that life expectancy has increased dramatically in the last 200 years, it is far more effective to show a video that shows how life expectancy has changed in multiple countries, and rather than showing snapshots from different points in time, video allows instructors to graph these changes as one fluid transformation in global health. 3. Video Can Be Persuasive and Enhance an Instructor's Credibility Particularly in the humanities and social sciences, instructors sometimes confront students who believe that many of the evidenced-based conclusions presented in the readings and discussed on the message board are little more than academic fantasies. In an age where people have opinions, as well as blogs from where they can publish those opinions, information in textbooks is often regarded with suspicion. Whether this creeping distrust of course information and the way in which it is presented should be welcomed or scorned by instructors, most would agree that gaining the trust of students is important. Video affords instructors the ability to transport expert testimony into a course, thereby giving students the opportunity to hear about a particular phenomenon from someone who has witnessed it first hand, or has at least spent an entire career trying to understand it. For instance, when discussing the torture of detainees who have been indefinitely held at the Guantanamo Bay detention camps, watching a video that features the testimony of a former detainee is of course informative, but it is also more credible, and in my experience, students will almost instinctively pay closer attention. 4. Video Can Promote Affective Learning I see the question of how to engage students in course material as really a question about how to tap into students' emotions, and on this score, video can be very useful. Hollywood feature films, television shows, and documentaries can be incredibly entertaining, and one reason is because they are the bearers of highly evolved narrative formulas, each specifically designed and tested to captivate audiences. Movies are adept at engaging people's emotions, so it is not surprising that people are often consumed by the characters, costumes, and trivia of their favorite movies. Tying together scenes from popular films and class content can be a very reliable way to increase student engagement. For example, rather than speaking an elegant explanation of culture into a camera, a sociology instructor might do better to assign a three-minute excerpt from the 2006 film The Devil Wears Prada, which lures the audience into feeling embarrassed for a fashion intern who fails to appreciate how the cultural logic of the fashion industry shaped her own decision to wear a frumpy blue sweater. Depending on the course and the way an instructor situates a video, one could undoubtedly list other strengths of video. My aim here is not to provide an exhaustive account of video's strengths but to simply point out that the usual way college classes are taught is undergoing a fundamental shift—far more consequential than most are aware. Like it or not, the train appears to be leaving the station, and online education is building an inertia that cannot be simply rolled back. Among the issues left to be debated is what to do about the loss of the lecture. As I have argued, even though video can never hope to replace the lecture, it will play a prominent role in online education. Lester Andrist I am very grateful for the many insights I have gleaned from conversations with Valerie Chepp, Paul Dean, and Michael V. Miller, regarding the strengths of video as a pedagogical tool.
