Virtual Teaching: Lessons in Shifting From Standup Classes to Online and Distance Learning. Why this work is important Schools and teachers are just now beginning to adapt to what students already know: Learning from afar or relaxing the time and place of learning profoundly enlarges the teaching and classroom environment. Definition of Virtual Teaching: (1) providing interactions of Students and Course material online (via E-mail, Telnet, and the World Wide Web) [different time and different place] (2) providing non-interactive presentations of Course materials via Television and/or Videotape [Same time, different place] when live broadcasts, and [different time, different place] when relayed via Videotape (3) providing interactive presentations of Course materials via Closed circuit, interactive Television and multiple receive sites. [Same time, different places] Online Classes Advantages and Disadvantages compared with Standup classes: € No classroom € Interruptability € No Travel; access at home via Computer € Shift from Centralized equipment/facilities administration to distributed student facilities/administration € Follows the VCR model: student convenience in rescheduling time and increased efficiency written [visual] emphasized over oral presentation [Auditory] € Student articulation [response improvements] € Adjusted cost in time for instructor (Course material preparation, update, maintenance) increased € Student interaction dispersed and increased; € travel time decreased; rescheduling of time flexibility increased Non-Interactive Television/Videotape Courses Advantages and Disadvantages € Recordable TV presentations for subsequent study €No direct Student-teacher interaction (after the fact only) € Harder to pinpoint/reference Instructor inaccuracies or Student misinterpretations of information € Harder to teach non-linearly [TV/Videotape time seen as more precious than in person time] Interactive Distance Learning Advantages and Disadvantages € Teacher can't see [remote] students € Students can talk to Teacher € Students can be identified by teacher both by voice and by system login € Teacher can bring to bear a variety of presentation modes: Prepared presention on Laserdisc or Computer, Ad hoc hand annotated paper and pen, classical Stand up lecture, Computer demonstrations € Teacher orchestrates the sequence of modes for the Interactive TV Broadcast. Traditional Standup Classes Advantages and Disadvantages € Immediacy of Students and Teacher € Natural Interaction among Students/Teacher € Variety of presentation/Teaching Styles € Less dependence on equipment € Scheduled Time and place € Centralized School resources dependence As can be seen from the consequences of these teaching modalities, moving from traditional Standup classrooms to Virtual classrooms requires planning and forethought to surmount the challenges and to exploit the opportunities for teachers, students, administrators and Course developers. Therefore, the discussion topic: How to transition to Virtual Teaching is proposed. Discussion topic: How to transition to Virtual Teaching Topics for discussion would include: (1) Mapping how the school registration, Instructor, and Support staff currently work to deliver Courses to Students. This is an important starting point, particularly if a school has no experience with Virtual Classrooms. (2) Diagramming multiple viewpoints, (of the Student, Instructor, Registrar, Computer system administrator). Virtual Classroom solutions can then begin to overlay the essentials of the course delivery. Questions like the following need to be resolved: € How can the Student register if not in person? € How does the Instructor contact the Student and inform them of how they connect to the Virtual (online) class (by the time the class starts)? € How does the Instructor know the student is who they say they are (throughout the course)? € How can the Student connect to the class using their own resources? € Should the class be on-demand or scheduled? € What is an optimal class size on-line? € What is the instructor/student class ratio? € Can multiple instructors serve much larger classes? € What are the requirements of the Computer Servers to handle multiple students in a class and multiple classes online? € What are the prerequisites of Students in terms of accessibility, Computer literacy (keyboard skills), Knowledge and use of Computer tools that will be Course implementing mechanisms, personality characteristics (sense of adventure, flexibility, independent, self-starting)? € What are the prerequisites of the instructor in terms of multiple kinds of accessibility, writing skills, knowledge and use of the underlying computer system and implementing mechanisms as well as the course content? € Dealing with unexpected situations (forgotten passwords, URLs, Client or Server Computer down times) (3) The transition continues with Developing the Course which requires new guideposts for the student, for whom this may be a brand new experience, and "how is it going?" mechanisms for the instructor to gauge whether communication and learning are taking place. Examples may include: € Extra tutorials (directed procedures for the students to follow) € Scheduled times for Students and Instructors to be online and converse € Instructor surveys of who is or isn't participating (who has not logged on to the server, how many and which URLs are being accessed) € Simply asking the student about the speed of the instructional delivery (Too fast? Too slow? just right?) € Getting feedback by giving a Course in Dress Rehearsal form or as "prevues" and making appropriate Course corrections (4) Conducting the Course requires concentration and a shifting viewpoint. Because of the heavy dependence on lots of computer and phone equipment, flexibility is essential. The facilities of the Computer system should be exploited. € Using mailinglists to deliver E-mail to the entire class membership at once. € Using Schedulers to send out tests to the class at a specific date and time. € Having multiple ways to be connected to the server using multiple windows (sessions) to accomodate real time conversations with multiple students concurrently. € Producing a diary of Instructor activity/happenings so the course can be faithfully replicated and/or repeated in the future. € Upgrading of Computing Systems, Network Downtimes are normal events € Remaining cognizant of student activity or inactivity, and abuse or denial of service. € Programs to determine last login or last E-mail they sent. € Contacting student also by phone or letter, in case of questions or problems. € Rehearsing commands/actions before doing them for real. € Creation of a Frequently Asked Questions File accessible by the students (5) Considering Open Issues in Virtual Teaching € Copyright/Duplication of Instructional materials € Adjusted time to develop and deliver instruction online € Course workload for Online classes greater than for Standup (Daily availability vs reduced travel time) € Designing Courses for minimal computer technology (That means E-mail only) provides the greatest accessibility for students, geographic, and multi-school participation. More sophisticated technology (e.g. audio/visual Web based) will scope the class and may exclude potential students. € What is the proper compensation for Virtual Teachers based on course size, and workload? € How to further verify real students? (6) Absorbing Lessons learned from [1] Standup to Online, [2] Non-Interactive Television/Video Tape and [3] Interactive Television: Standup to Online € Use online counterparts to standup classes (e.g. class questions and discussion = mailinglist; Individual question and answer=E-mail messages, Hand annotated grading of homework and tests=Computer quotation of annotations in Email to ease the Training effect on your Students and allow them to more quickly adapt. € Time lag to return graded material severely reduced € Standup Classes can benefit from providing Course materials on the Web and teaching from them. Non-Interactive Television/Videotape € Not purely one mode of presentation; also used Express mail, Web site, mailing list among students, E-mail to Grading assistants, professor, proctor; € Frustrating Time lag between when homework, tests handed in and graded work returned € Frustrating Time lag between when questions were asked of Teaching assistants or instructor and when they were answered Interactive Television € Can't See Students, This affects visual presentation of instructor, who must face the camera and make believe it's human to come across as talking directly to the viewer. € Teaching in an empty Studio. Audience is totally remote. The energy expenditure is much greater than when face to face where an energizing exchange can occur. € Teacher must use Commerical TV-like gimmicks to maintain the attention of the student. (i.e. Outrageous statements, visual gags, (i.e. disembodied (3rd) hand as pointer to chart) I envision that the roundtable would talk about the virtual classroom models in turn where participants can discuss what techniques worked or didn't work to overcome the limitations or exploit the inherent opportunities made available by the medium.
