  2. Internet Connectivity Speeds • T1 – Trunk Level 1 • Digital transmission link • 1.544 Mbps • 24 voice quality lines (POTS – plain old telephone service) • Fractional T1 – Channelized T1 • Some of the channels turned on • 384kbps • 512kbps • 768kbps • T3 line – DS3 • 45 Mbps • comprised of 28 T1 lines • fast enough to transmit full-motion, real-time video • typically installed as a major networking artery for large corporations and universities • DSL – Digital Subscriber Line • Variable speeds – sold in terms of download and upload • 786kbps / 384 kbps • 512kbps / 128 kpbs • 1 DSL line = 2 analog telephone line EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  3. Distance Education Technologies • Correspondence Courses • Snail mail • E-mail • Web-based course • Audio / Video tape • Asynchronous • Teleconference • Synchronous • Videoconference • Synchronous EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  4. What are the models? • Supplement existing classes • Language • Science • Math • Replace existing classes • Virtual school EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  5. Issues • Curriculum • Who is in control? • Access • Advanced Placement courses only? • Science courses only? • Only during 3rd period? • Technology • Local academic support EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  6. Issues… • Who are the teachers? • Teachers from other districts? • Teachers from other states? • Parents? • Subject Matter Experts? • Are the teacher’s licensed? • In the state? • In the subject area? • Funding… EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  7. “As stipulated by the Florida K-20 Education Code (s.1002.20), parents have the right to choose educational options such as Florida Virtual School for their children. A student’s full-time school may not deny access to courses offered by FLVS assuming that the desired online course(s) is an appropriate course placement based on the student’s academic history, grade level, and age.–” http://www.flvs.net/_students/index_st.htm EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  8. Any time, any place, any path, any pace • But is this true? • Time • server maintenance • 9th grader online at 4am? • Place • As long as there is electricity and internet connectivity • Path • Allowing students to take courses out of sequence? • Pace • School quarter / semester / year EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  9. Maryland Virtual High School of Science and Mathematics “Preparing students to “do” science in the real world of the future means guiding them in “doing” science now. The Maryland Virtual High School of Science and Mathematics entails bringing to the classroom the same team problem solving, technology rich approaches currently used in research and business.” http://mvhs1.mbhs.edu/mvhsproj/bground.html EDUC W220 - Technical Issies in Educational Computing - Riad S. Twal

  10. Maryland Virtual High School of Science and Mathematics • October 1995, Montgomery Blair High School • Three year grant • $1,500,000 • National Science Foundation • computational science studies • Internet use for science resources, mentoring and collaboration EDUC W220 - Technical Issies in Educational Computing - Riad S.
