introduction
Introduction
  • Two widely used distance learning methods are:
  • IRI (Interactive Remote Instruction) combines key features of both methods. It has been used for the past 4 years in regular credit classes.

degree of interaction
Degree of Interaction
  • “In its most fundamental form education is interaction among teacher, student, and subject content.”
  • Increasing the degree of interaction increases effectiveness and satisfaction.
  • When comparing traditional environments (2-way audio, one-way video and traditional classrooms) with IRI, the perception of classroom interaction of the IRI group is consistently higher.
recording architecture
Recording Architecture
  • Recording is based on a passive “participant” that records the session.
  • Playback is based on an active “participant” that plays back on demand.
  • The architecture allows us to mix live with recorded sessions.
  • Storage: anywhere from 300MB to 1GB/h.
recording and review
Recording and Review
  • IRI session recording and review are completely controlled through Java applets.

status and future work
Status and Future Work
  • IRI has evolved into a reliable system.
  • We plan to continue use of this UNIX version for classes over the next year.
  • We are currently designing a platform independent version, Java based, with an emphasis on supporting at-home class members.
