Online Learning Today: Not Ready for Prime Time In May 1997 Robert Marshall, a professor at an urban East Coast University, was submitting his grades for his course, Introduction to Cybermedia. It was the third time he had taught this course he created in 1996, in response to the growing influence of the Internet and World Wide Web in his mass communications discipline. But most of what was on his mind was how to evaluate and describe the experiment he had just concluded. For this semester, Introduction to Cybermedia was taught totally online. There was one class meeting. All the interaction between him and his students was electronic. The only formal contact students had with each other was also online. How did the students feel about this approach to education? Were they well served by the online format? How did he feel about this pioneering journey? Was it satisfying? Would he recommend the technique be expanded at the University? What worked, what was missing? Robert Marshall was not a computer expert.. But over the years he had found that various computer applications had helped him in his research and writing at the universities where he worked and taught. In early 1995 he had his first experience with the World Wide Web. His first, second and third impressions: this medium is not a fad. It had substance and depth. The subject of the course was the the process that was employed for conducting it -- the Internet and the World Wide Web. The course was officially in the School of Communications at the University. Dr. Marshall created the course and first taught it in a conventional class room setting in the Spring 1996 semester. It was repeated again as a classroom course in Fall 1996. This time it was held in one of the University's new "Smart Classrooms," which included multiple network-connected PCs and a large projection display. In the first iteration, only about one third of the readings were available online. For Fall 1996 Marshall was able to find more material online. By the time of the online course the only two books that the students used were Nicholas Negroponte's Being Digital and Learning to Use the World Wide Web, by Ernest Ackermann. At the end of the course, both students and instructor had some very firm opinions and observations on the pros and cons of teaching and learning online. From Marshall's perspective, the negatives outweighed the positives. But, as described below, for some students anything lost by going online was more than compensated for by what they gained. For some students, half a loaf was better than none. First, some background on how an online course came to be offered at a traditional university. Then some detail on how the students evaluated their experience. Finally, Marshall's take on the "virtual classroom." Information technologies have been changing education since the development of written
language. Writing and books replaced the oral tradition in most societies. The printing
press made books and periodicals more widely available. The stream driven press and trains
helped make free, mass education a reality. Sunrise Semester notwithstanding, television has proven be to be niche player in formal
education, even 50 years after its commercial introduction. Then came the Internet. Essentially this brought together the personal computer, less than 20 years old as a viable product, with the telecommunications network, well over 100 years old, but never closely associated with the education process. The glitzy part of the Internet is the World Wide Web. Although its genesis dates back all the way to 1991, its popularization can be traced to the commercialization of the graphic browser by Netscape in 1994. There are three characteristics that made the Web such a promising development that earlier uses of the computer missed.
What has so far been the "killer application" of the Internet -- the reason
more people initially set-up and log-on -- appears to be electronic mail and the related
forms of communication, such as distribution lists and UseNet groups. Although information
providers like to believe that the Internet is about content -- and it may be some day --
the content most people claim to desire for now is that which they create and receive in
the form of personal and targeted messages. Online Course vs Distance Education Distance Education (sometimes Distance Learning) is a phrase that applies to any number of techniques that evoke the notion of students and teacher being in different places. The original distance education format was a correspondence course, using the mail service. Telephony and broadcasting added another possibilities for conducting at-a-distance courses. Most popular has been various video approaches. Some early versions, such as Sunrise Semester in the 1950s, involved using one-way broadcasting for the instructor to reach the students, then mail for submission and return of materials. Video conferencing has been the latest iteration of distance education. Using satellite or terrestrial links, an instructor in one location can meet with a class in a distant location. The return path from students to teacher might be a simply telephone-based audio hook-up. But with increasing capability of computers and telephony, systems such as Intel's ProShare and elaborate networks, such as LearnLinc, are making two way video between instructors and multiple remote sites feasible. Distance education courses using video conferencing, however, are like traditional classes in that that are synchronous, or real time. That is, students have to be in the remote classroom or at the connected PC at the appointed day and hour for the class. An online course, on the other hand, is asynchronous. Like a correspondence course, students can work whenever it is most convenient. The instructor need not be at a specific place at a designated time. This has the advantage of allowing students to participate whose work or personal schedules did not allow them to attend a fixed-time day class. It also means that students need not travel to the site of a video conference, opening up the course to an infinite range of locations. Introduction to Cybermedia Marshall's personal aspiration for the course was that it would be a vehicle to attract a true distance insensitive class. For him, the value of an online format was to provide the wherewithal for those who could not come to a classroom at the University at an arbitrarily fixed time several times a week to take the course. The University did little marketing for the course. Marshall put out some news of the course on a Listserv of journalists, and others involved in online news and had several responses, from as far away as Seattle and Toronto. In the end, most of the students, however, turned out to be matriculated undergraduate students. One student lived in another state and was trying to finish his degree without having to be on campus. As it happened, he was also blind. Another student, Marshall learned, took courses on campus but was confined to a wheel-chair. For him, the online format reduced the days he had to be on campus. Several other members of the class made it clear that because of their daytime jobs, they could not have taken this course. For the most part, those enrolled did so because they wanted or needed this course and they learned incidentally that it was being conducted online. They didn't seek out this format. The Hazards of Being a Pioneer The seven Online Learning (OLL) courses the University offered in Spring 1997 were the start of the OLL program. A few previous forays involved several course that mixed regular class meeting with online elements or were established from the start as continuing education courses. This meant that the OLL office, staffed by a part-time faculty member and several
graduate student assistants, did not really have all the contingencies and policies in
place for organizing online courses.
Based on some reading he had done about online conferences and literature about the benefits of personal contacts making later telephone conversations more effective, Marshall decided very early that he would schedule one class session the first week of classes. Months before registration, Marshall included on the homepage for the course-to-be that there was a required three hour class on the first Saturday morning of the semester for anyone living within 150 miles of the University. The first hint of the problems Marshall would face came during the semester break that stretched from early December through mid-January. He wanted to make sure that all those who were registered know about the Saturday meeting. Marshall contacted the University, asking for the e-mail addresses of those who were registered. He learned they didn't have them. After several weeks, the University faxed him a list with email addresses of most of the students, with postal addresses for those who did not have e-mail. He signed them on to a Listserv he had set up and started a series of email messages. Marshall told them about the class meeting and asked that they e-mail me confirmation of receipt. Not much happened. Marshall eventually learned that the list of -mail addresses was not from self-reported addresses. Instead, the computer people simply "fingered" each student and copied the e-mail address they had been assigned by the University. There were several problems with this.
Thus, it was not until the first several days of classes that Marshall began getting
e-mail in response to his Listserv and e-mail messages of weeks earlier. In other cases,
students heard nothing (they were not checking their long-forgotten University accounts)
and called or came by his office. Prof. Marshall had five goals for the one class meeting:
Ultimately, the session was well attended, though not everyone in the class got word of it, for reasons already explained. By and large Marshall believed the goals he set were achieved.
Skills Students Had vs. Skills Needed In the year between the first offering of Introduction to Cybermedia and the online course changes in technology lowered the skills needed to create the course materials. Foremost this included HTML-creation software that largely eliminated the need to learn and write the code to create Web pages. From the students' perspective, the cost of personal computers continued to drop, while capabilities increased. Modems capable of 28.8 kps became standard and inexpensive, replacing the 14.4 modems still common a year earlier. PCs with sound cards and speakers, capable of playing the sound transmission offered on many Web site, also were more widespread. What did not seem to change in that year was the overall familiarity with computers and the Internet that students brought with them to the course. The baseline survey Marshall conducted in both 1996 and 1997 found that while most students claimed to have a reasonable comfort level with PCs, they greatly overestimated their capacity to use the WWW. For example, most students claimed to use e-mail at least weekly prior to the course. But for many of these, this meant accessing their university accounts using the primitive UNIX-based ELM or PINE software, in ASCII mode. This is what the university offered on most of its student-accessible computers. Few students had learned how to use graphical e-mail programs that allowed them to cut and paste into and out of the mailer. Few had ever sent or received an attachment or set up filters. Students who had initially claimed familiarity with the Web came to realize that they did not really know how to use it beyond the very basics. For example, they had little experience with searching capabilities or techniques. Moreover, in the end of semester student survey (and only then) did many students complain of how uncomfortable it had been to read so much from a screen. Some students, as well as the instructor, routinely printed hard copies of most readings. Print not only has higher resolution than the screen, but it offers portability and accessibility for later review. As it turned out, many students who used the university computer labs could not (or did know think) they had the capability to print out the many pages of readings that they were assigned online. Instructors of new online courses also need a set of skills that go well beyond the subject expertise they presumably have. Regardless of the course content, instructors need to be able to create Web pages using HTML or application programs that add the coding. They must understand and then learn still nascent elements of Web site design: when and how to use tables as a formatting device, using frames, adding graphics, perhaps audio as well, and creating hotlinks. They must learn the arcane commands for uploading files to the server housing their site. (If available, they could also employ a knowledgeable student assistant to handle this. Of course, it adds to both the financial and logistical cost). And they must master the subtleties of e-mail systems using filters, signatures and auto-reply messages to be able to efficiently deal with the onslaught of e-mail generated by an online course. Student Evaluation of the Course
Community. One of the most frequently heard criticisms of the Internet (mostly it seems from those who have spent little or no time using it), is that it will "isolate" us. People will stay in front of the computers for their entertainment, shopping, information gathering. Although many students lamented the lack of classroom time, they also found that the extensive use of e-mail and the Listserv made them feel closer to their classmates than in a traditional physically-based class. Here is how some of them expressed this sense.
The things students liked least: Desire for classroom: Despite the feeling among some students that they were able to get much from the interaction online, there was at least as great a feeling that they missed the characteristics of the classroom experience. It was expressed in different ways:
Lessons Learned Bearing in mind that some of Marshall's observations may be the result of these types of artifacts, he distilled some of the lessons to be learned from this pioneering venture. Some, as he notes, should become less salient as the procedures for offering such courses get ironed out. Others will improve as the technologies involved are honed and become more widespread. But other variables are likely to be need permanent attention in any move to online formal education. 1. E-mail management is critical. This is a weightier issue than it may seem to those who have not used e-mail often. But it may also surprise those who are experienced with e-mail. A class of 25 students is likely to generate in excess of 50 pieces of e-mail per week -- occasionally far in excess. The e-mail comes in at least three flavors:
Assuming that the instructor is already receiving e-mail from colleagues, friends, and other Listservs, the need to filter and file e-mail from the students becomes critical. The instructor needs to be able to respond to questions from students, keep Listserv discussions on track or add his or her own comments, and most of all to make sure that required assignments are accounted for. Employing e-mail software that allows setting up of multiple level filters is a a
minimum requirement. Then it is crucial that students be instructed how to send mail. For
example, if an assignment is about looking at online newspapers, the instructor must
require students to use as the subject something like "Subject: Online
newspapers." Left on their own, they might use any subject and the e-mail will either
get buried or will require the instructor to manually transfer dozens of messages into the
appropriate mailbox folders.
As with any course, subsequent presentations of the course will take less effort. But unlike changing some notes in a lecture by crossing out and inserting, any change in a Web site may involve new files and uploads, new hot links, or discovery of links that no longer work.
In an asynchronous online class, each student's queries must be addressed one on one. Netiquette says one must not answer individual questions on the Listserv. Of course, sometimes it is appropriate to "broadcast" a response that may be in response to an e-mail that has broader application than to one student. To a great extent, however, everything is one-on-one. See also the first point. Typing out responses to these written notes is generally more labor intensive than a few sentences in class.
It is presumably possible to inform students that the instructor will respond to e-mail only on weekdays during some "virtual office hours." But this approach goes against the grain of the Internet. It is analogous to a newspaper with a Website edition continuing to update content only on the same 24 hour cycle that was acceptable for the old print newspaper. The technology allows for greater currency. This does translate into a higher level of user expectation. Marshall found e-mail from students waiting for him at all hours and days. Even when traveling he checked in with his notebook computer. 4. Frequent feedback needed to and from students. College students usually have quite a full plate. Given the demands on their time, they tend to concentrate on that which is most urgent, not necessarily on what is most important. With no set class to attend, no traditional need to show up to listen to the pearls of wisdom from the instructor, they can easily put off dealing with a nearly invisible course. As one student wrote in the course evaluation:
Thus, instructors who are used to assigning a few papers, a term paper, a midterm and final will find a need to be more concrete in their assignments. Students should be expected to "raise their hand" at least once a week. Using the Listserv or other discussion group programs can further replace the "class participation" component of a traditional class. Students also need feedback from the instructor. This may be in the form of comments to posts in the discussion groups. Marshall was unsure of how often or substantively he should jump in to the class' online discussions, usually on the subjects he initiated as assignments. He received an answer from one student's evaluation comment:
Needed Developments for Online Education Online courses have a place in university education. The technologies will continue getting easier to use, cheaper to provide, and both students and teachers will become more comfortable with the process. The Web -- and its users -- have come a long way in a short time. It would be a mistake to write off online education based on the limitations of today. Still, several developments will need to come together before the Internet will likely be able to go much beyond a vehicle for serving education niches. 1. The addition of audio and video. Both, of course, are available today. Audio exists as downloadable files, as well as the more convenient format of "streaming" audio and video such as that provided by Progressive Networks' RealPlayer. But the server software is not as widespread as the client software for displaying the output. Moreover, although new PC's include sound cards and video cards with the two mb or more that are needed for decent video, there are many computers still on desktops, including in university labs, that are not sufficiently equipped. Furthermore many instructors do not have the skills needed to create audio files, yet alone video files. Finally, audio and especially video files, even with the strides made so far in compression, still take up large chunks of disk space. One minute of video typically requires about 3 mb while a similar length of audio is about 640 kb (this can vary depending on the compression used and the resolution and fidelity required). Even with the falling price of mass storage, storing extensive audio and video files can quickly mount up. 2. Widespread broadband. Audio, video and even more use of graphics will not accomplish much at 28.8 kps access. Even at 56kps, both video and audio are unreliable. Video is displayed in a jerky two inch window. Streaming audio can stop and start. Students using a university's network have some advantage. But the point of online learning is that it should be accessible from remote sites. Thus, until some broadband pathway or pathways become economical and widely available, the audio and video needed to help make online education comprehensive will have very limited application. There are indications that broadband is happening. Several cable TV companies and consortia are finally moving forward with cable modem service. These included TCI-lead @Home, Time Warner Cable's Roadrunner, and MediaOne Express. Hughes Electronics, largely responsible for the DirectTV satellite TV service, also offered an Internet service called DirectPC. It had announced the availability for 1997 of a single dish that would combine both services. And the telephone companies, having botched their potential of 128kps ISDN service, were experimenting with ADSL, a broadband technology using existing copper wires to the end user. 3. Expectation of access from each dorm/home. By 1997 most colleges and universities had extensive Internet access. Initially it was from clustered sites in libraries or "labs." Many were completing wiring to dorms as well. But it is access from the home that gives online education its fuller potential. In 1997, somewhat over 40% of U.S. households had personal computers. But more than 50% of households with school age children had PCs. Although that includes older PCs without modems, virtually every PC sold by major vendors for the past several years have included modems. And at $200 or less for a 56 kbs modem, it is a small expense compared to the PC and the Internet access service. Moreover, PC prices continue to fall, with the cost of Internet-capable PCs available for under $1000. WebTV, the label for a set-top box to turn any TV into a Web-capable station, is under $400. These trends suggest that there should be a growing expectation that the universe of online learning capable homes will continue to grow over the coming decade. The Future of Online Education Reflecting on his foray into online learning course, Prof. Marshall came away from the experience convinced that online education had place in the quiver of delivery alternative for higher education. But he also felt strongly that it was as a supplement to traditional class, except for some niches, where it could complement campus-centered education. High cost option. Administrators should disabuse themselves of any illusions that online courses will be labor saving. Quite the contrary. The almost tutorial nature of this format actually supports a position that faculty should be responsible for fewer online students than in-class student in the same course.. Figures from instructors who have been through the experience have proposed that the optimum number of students for an online course today be in a range from 15 to 20 students. Marshall agreed that beyond this number teaching assistants would be needed to assure that communication with students is maintained. Online may create new possibilities for what used to be known as extension courses. To the extent that students who otherwise could not attend a local campus could enroll in an online course, universities can expand their enrollment. As an adjunct to traditional classes. Many of the techniques and tools used in an online course are also useful, of course, as an adjunct to traditional classes. Many instructors are employing Listservs and other discussion groups. E-mail is becoming routine. Providing assignments using the Internet for research and for links to readings can supplement and enhance many courses. Marshall felt that instructors who continued to resist using the Internet and Web would be short-changing their students. There was no subject where a Listserv, discussion groups, or links to resources could not be used to enhance communication and learning. Indeed, it is far more likely that in the foreseeable future online will do for a traditional in-class experience what other technologies, such as the steam driven rotary press, wood pulp paper, graphite pencils, paperback books, and film and audio tape did in earlier generations. They are among the tools that teachers can use to enhance the learning of subject matter. While the Internet may have a greater impact than than many of these (and at least comparable to the press), it appears unlikely that it is poised to replace the classroom as the primary teaching and learning environment. As a substitute for class only when distance is truly impediment. Marshall's University initially offered its online classes as a substitute for offering a traditional class. That surprised Marshall, who had expected the classes to be marketed more widely as a way of attracting nontraditional students: those who wanted or needed a course but because of distance or physical limitations could not come to campus. As it turned out, only one of his students truly fit that category, a blind student who lived in another state. Several others were matriculated students who had full time day employment and previously had been taking courses offered only in the evening. As a course only offered during the day, they were able to take it due to its online incarnation. For these students, the limitations imposed by an online course were likely outweighed by its benefits: a half a loaf is better than none equation. But the bulk of the class, many of whom claim to have enjoyed the experience, were otherwise candidates for the in-class version of the course, as offered in previous semesters and scheduled for future semesters. They could still have had their assignments on a Web pages and used hotlinks to the readings. They could have submitted assignments by e-mail and participated on the Listserv. Exams could have been offered online, with a flexible deadline. Moreover, they would have queried Marshall and he could have responded, in real time, to the class. No amount of asynchronous broadband capability can substitute for the spontaneity and serendipity available in the interaction of a group time people reacting in real time. At least, thats where Prof. Marshall came out of his experience. University Policy Issues College and universities that want to offer online courses will have to address a range of policy issues. Among them are:
Although Dr. Marshall says he will certainly employ many of the techniques he used in the online course in his conventional courses, he will wait until these and other issues are ironed out before he will teach an online course again. |
