SLNSynchronous Learning Networks

• Same-time, Same Place
• Kindergarten Show and Tell
• Learn by discovery in groups
• In-class discussions coordinated by Instructor
• Student-student, student-instructor Interaction,
  Interactive Demos, Simulations?
• Same Time, at a Distance
• Streaming Video/Video Conferencing
• PC-based ISDN, H.32x, ATM Solution
• 2-way audio, 1-way video, 2-way audio
• Interactivity?

6
What is ALN?

• Asynchronous
• Not at the same time
• Not at the same place
• Distance Education (Teaching,Learning)
• (real-time or delayed TV, 2/w Audio Video)
• Some early examples
• Correspondence courses, books, audio tapes, Video
  Tapes via snail mail or courier
• Not new...but now information (not physical
  media) delivered via the Internet.

7
What is ALN?

• Learning
• Cognition - How do people learn best
• Teaching and Learning Styles matched?
• Synchronous Learning
• Central Institution of Learning - The University
• Professor and student in same time and space
• Benefits of physical presence Interactivity
• Our aim in Lectures on Demand in ALN
• Construct a learning environment using
  information technology which enhances and mimics
  effective interactive and collaborative
  synchronous learning networks

8
What is ALN?

• Networks
• of computers?

9
What is ALN?

• From the ALN Web http//www.aln.org
• ALN is a network of people facilitating learning
  that is largely asynchronous. It combines
  self-study with substantial, rapid, asynchronous
  interactivity with others.
• Frank Mayadas http//www.sloan.org
• Learning Outside the Classroom - ALN
• On-campus, Near-to-campus Far-from-campus
• Sloan Funding single course, degrees, system-wide

Some major issues in ALN

• Quality of ALN courses, Accreditation
• What has made the great institutions of learning?
• Greatest resource and asset World class faculty-
  combined scholarship, teaching and research.
• Instructors must add value!
• System of education, high standards of
  excellence.
• Make better traditional in-class teachers
• Synchronous Learning Networks.
• Collaborative, Active Learning.
• Learn it best by teaching it
• Questions-participation-exploit the physical
  presence.

Quality of ALN courses

• Will Good ALN Courses make the professor
  redundant? Self-obsolescence?
• Those who are worried that they will be replaced
  by a computer - should perhaps be!
• Must add value - updating ALN courses regularly.
• Traditional non-interactive lectures do a very
  bad job at teaching!
• Poor quality teaching of any type does not work!!!

Lecture vs Teacher

• The teacher has not taught if the student has not
  learned..
• Value added by Instructor by what the Instructor
  says and does
• Facilitator or learning-motivate, excite, provide
  insight, practical realism, research perspective
  personal enthusiasm infections
• interactive class sessions, mini group activities
• sensitivity to different learning styles
• The mechanics of learning, cognition-all senses
• Need for instructional Designer, Peer Review in
  ALN

University of Florida ICEE99
22
Another Issue Time and effort to develop ALN
courses

• Many good instructors teach in a prepared,
  structured but spontaneous and adaptive manner.
• Resistance to canned lectures
• Demand on faculty to change their mode of
  teaching-suppress spontaneity
• Make it easy, reliable and proven-not left to
  chance

23
Time and Effort to Develop and Offer ALN Courses

• Lectures on Demand-Ease of Development of ALN
  materials
• Direct incorporation of the spoken, written and
  other facets of natural communication of the
  instructor into the ALN mix
• Post-production of supporting ALN
  materials-possibly with student assistance
• Students teach each other-less instructor
  intervention(e.g. E-mail slave.)

Careful and Effective Use of IT

• Johannes Gutenbeg-Printing press
• Color printing with images
• Sound, video communications
• Interactive graphics - simulations - virtual
  reality
• MediaPrint, Video, Audio
• Information-digital information(IT)
• Incorporate all of these in ALN Lectures on
  Demand
• New electronic interactive multimedia books
• or learning resources, simulations, etc.

How it All Works

• Web page reference URL to content
• Server sends metafile to browser
• Browser sends metafile contents to player
• Player reads contents and requests it directly
  from server
• Server streams the presentation
• Player plays the presentation
