Engaging Lecture Capture: Lights, Camera… Interaction!Engaging Lecture Capture: Lights, Camera… Interaction!
It might sound strange to use the word “interaction” when talking about course lecture capture, but interaction is the key to engaging students. Lecture capture is “a solution that captures classroom-based activities in a digital format that is then available for download or consumption over the internet.”1 In the College of Computing and Digital Media (CDM) at DePaul University in Chicago, this technology began 10 years ago with the development of their proprietary Course OnLine system. This system captures video of the instructor, two whiteboards, and whatever is displayed on the instructor’s PC, including PowerPoint presentations, Excel spreadsheets, or other software (see Figure 1). Lecture capture serves both in-class students, by augmenting the classroom sessions, and online students, by replacing the classroom lecture. Faculty members are recorded as they teach the in-class section, while the online section watches the recording during the following week. The sections share the same learning outcomes, assignments, and exams.
Figure 1. Lecture Capture Screenshot from Course OnLine In addition to Course OnLine, a variety of solutions are on the market from Accordant, Echo360, Elluminate, Panopto, Sonic Foundry, Techsmith, and Tegrity. A few key players dominate the market, with Sonic Foundry holding a hefty 40 percent-plus market share (including the education, government, corporate, and health care sectors). Just a handful of vendors provide the lecture capture systems in use at most major universities.2 The recent partnership between Blackboard and Echo360, which the companies claim offers a seamless solution for Blackboard users, will certainly increase the use of this technology in the future. Lecture capture has found an important and permanent place in education.3 According to Ramaswani4:
Is the cost and time outlay in these systems worth the investment? Does lecture capture engage students and help them learn? The research to date has found a perception by students that it does; however, there is limited preliminary research on how it might impact actual learning outcomes. In a study of 29,078 in-class students at the University of Wisconsin–Madison,5 which used lecture capture to augment their classroom experience, 82 percent of the students would prefer a course in which lecture content is recorded, and 60 percent were willing to pay extra to have this technology available to them. Students cited the benefits of:
One student noted:
At Temple University,7 faculty and students perceived that lecture capture improved student learning and helped with exam preparation. Lecture capture had very high approval rates by both faculty and students, and 95 percent of the students said they preferred taking a course supplemented by lecture capture. At Coppin State,8 using course capture to augment the class increased retention.
There is very little research on using lecture capture for online-only students. When the systems are used by online students without the benefit of the in-class experience, the results may differ. In a focus group of in-class students using lecture capture:
Online students don’t have the benefit of meeting the faculty and other students first, and then using the lecture recordings as an additional resource. The classes are recorded, and the online students view them later. They rely on the lecture recordings as the primary mechanism to interact with faculty. Although the research supports that students perceive webcasts to be a helpful learning tool, the impact on grades, test scores, and learning is not clear. While existing studies do not demonstrate that lecture webcasting has a positive impact on learning outcomes, they do seem to indicate that the availability of archived lectures improves the student experience.11 A report from University of Texas at Austin indicates that “exam scores did not differ in a statistically significant way between the webcast and no-webcast sections.”12 A small study at Coppin State University13 that compared face-to-face classes both with and without course capture found that students in face-to-face classes that used course capture received slightly better grades than those in classes without. To improve actual learning outcomes, pedagogy should include interactive discussions and activities.14 Successful course lecture capture requires a well-defined strategy. Developing the knowledge, skills, and attitudes necessary for delivery needs to be systematically achieved. Just as in the pyramid of Maslow’s Hierarchy of Needs,15 where the physiological and then safety needs must be met before higher level needs are met, the same holds true for lecture capture. Faculty must learn how to use the lecture capture system and then the technical fundamentals before advancing to integrating interactivity and improved learning outcomes. (See Figure 2.) For example, it is impossible to explain the complexities of network security when you forget to turn on your microphone!
Figure 2. Lecture Capture Developmental Hierarchy Lecture Capture System Polices and TrainingLaying a solid foundation for successful lecture capture requires the institution to address three areas:
Lecture Capture SystemsIt is important to purchase or develop a system that accommodates a variety of teaching styles and does not require faculty intervention. For example, MScribe, the pilot developed by the ATLAS Collaboratory Project at the University of Michigan, utilizes a robotics tracking system that follows the lecturer as he or she walks about the lecture space wearing an infrared-emitting necklace. Purdue University is putting standard lecture capture technology in classrooms, yet David Eisert, manager of emerging technologies at Purdue University, indicated that faculty members said they would not even be willing to press a button at the beginning of class to initiate the recording. As a result, Purdue found a workaround that would require minimal cooperation form professors.16 Faculty are educators and need to concentrate on the content and presentation — they should not be expected to become technical experts as well. Technical support staff should implement, test, and maintain the equipment (including back-up supplies like extra whiteboards and cameras) as needed. GuidelinesDevelop clear guidelines regarding the use of lectures and communicate them to faculty before a course begins. While some lecture recordings from past classes (with a guest speaker, for example) may be used again, most lectures should be fresh every class to incorporate new information, trends, and current events. A policy for missed lectures, make-up lectures, and so forth should be communicated to faculty so that they are clear on how and when the lectures will be recorded. In addition, a procedure should be instituted for faculty to request that a certain class or entire course not be recorded. While lecture recordings are beneficial for the majority of courses, class discussions in courses that address personal topics or controversial subject matter might be adversely affected if recorded. TrainingEducate faculty on the best practices and limitations of lecture capture. Ensure that faculty members are trained to explore methods to integrate their pedagogy with lecture capture. (See this sample course lecture capture that instructs faculty on the topic.) Figure 3 shows the opening screen for the Course OnLine documentation web page on lecture capture, which has many recordings and tips from faculty on best practices.
Figure 3. Course OnLine Lecture Capture Resources According to Traphagan:
Technical FundamentalsLecture captures should be approached as an iterative process. Faculty should practice the technical fundamentals required before, during, and after the class session. After going through this iteration, the learning from watching the captured class will lead to changes that can be implemented before and during the next class. Below is a checklist of practices that faculty should address for each recorded class session. Before Class
During Class
After Class
Integrating InteractivityAlthough mastering the technical fundamentals is a critical step, more should be done. A survey of 1,117 online learning students at CDM in the spring of 2009 demonstrates this point. Of the 373 students who responded (33 percent), many had positive feedback about the technical fundamentals. (See Table 1.) However, a closer look at their comments shows that in order for them to be fully engaged, faculty need to integrate interactivity. (See "Interactivity" for specific student comments.) Table 1. Survey Results about Lecture Capture Technical Fundamentals
Faculty members should create opportunities for students to participate after the class lecture by asking questions to be answered later, and then following the lecture with asynchronous discussion boards, synchronous chat, or blogs. Some lecture capture systems allow synchronous virtual classrooms to run in tandem with the lecture capture. CDM students in the survey view this as an attractive option. Remote students crave the interaction that in-class students get by attending class. The interaction works to motivate both the strong students and those who are struggling.
Applying the seven principles for good practice22 will help faculty reach all students though integrating interactivity. Significant changes in teaching and learning are possible, particularly when interactive technologies are involved. These changes promise to better engage the Net Generation and the adult learner.23 Table 2 relates Chickering and Gamson’s principles to specific practices for adding interactivity to lecture capture. Table 2. Seven Principles for Good Practice Applied to Lecture Recordings
Improved Learning OutcomesThe research to date has focused on student perception of value rather than actual learning outcomes. Continuing to improve lecture capture technology, while important, simply builds the foundation of the pyramid. The greatest increase in the effectiveness of lecture capture systems will come from the application of pedagogical techniques that integrate interactivity. Once some instructors have successfully integrated interactivity, we can measure the effect on actual learning outcomes. Given the magnitude of positive perceptions surrounding the effectiveness of lecture capture systems, the impact on learning outcomes might be significant and warrants further investigation. The College of Computing and Digital Media plans to continue research in this area as more instructors adopt changes in pedagogy while recording their lectures. Data that demonstrates significant increases in student learning will be the motivating factor for instructors to move beyond the technical fundamentals and toward integrating interaction in their own courses.
