The Centers Mission

• The Intelligent Systems Application Center (ISAC)
  creates software applications and hardware
  prototypes that will be used to enhance
  educational delivery.
• The applications combine interactive multimedia
  and artificial intelligence technologies.
• Software is evaluated for usability and
  effectiveness.

Areas of Focus

• Engineering and Science Education
• ITS
• Virtual Laboratories
• Virtual Experiences
• Health Education
• Cancer Treatment Alternatives
• Virtual Patients
• General Education
• Virtual Teams solving Real Problems

Interactive Multimedia Intelligent Tutoring
System (IMITS)

IMITS Content

• Covers a two-semester course in introductory
  electric circuits
• DC Circuits
• AC Circuits
• Transient Analysis
• Laplace Transforms
• 80-100 hours of material
• Eighteen Projects

IMITS Scenario
8
What Makes It Different From Other ITSs ?

• Project Centered
• Student Controlled
• Teaches Concepts and Encourages Critical Thinking
• Extremely Rich in Material
• Emphasizes Understanding
• Stresses Communications

9
Effectiveness Study

• Two major questions guided the evaluation of the
  softwares effectiveness on learning
• 1) Did students who used IMITS (experimental
  condition) learn more (e.g., score higher on
  achievement measures) than their counterparts in
  the control condition?
• 2)Did performance on the IMITS embedded
  learning objective questions improve the more the
  software was used?

10
Effectiveness Study

• Two universities (Rowan and Temple)
• 127 students R (78), T (49)
• Results
• There was support for the effectiveness of IMITS
  using classroom measures. For each cohort, the
  software group outperformed the control group (at
  a statistically significant level) on two
  classroom achievement measures Labs 4 and 5
  (DC 5 problem) (Cohort 1) Lab 4 and Exam 3
  (Cohort 2), and DC assignments 3 and 4 (Cohort
  3).
• There was very strong evidence that IMITS works
  to improve learning engineering concepts in
  introductory circuits courses. The more students
  used the software, the better they performed.
  All things being equal, that is, taking into
  account grade point average, race, and school,
  for 10 learning objectives, the number of
  questions encountered predicted learning gain on
  that objective.

Prostate Interactive Education System(PIES)
12
Specific Aims of PIES

• To develop a computer-based intelligent system
  that provides patients with up-to-date
  information about prostate cancer, its treatment
  options, and its side effects.
• To evaluate the usability of PIES and to assess
  with early-stage prostate cancer patients the
  programs effect on prostate cancer knowledge and
  on treatment decision making

INVISSIBLE

• Develops an innovative curricular approach for
  scientific literacy in biology that is driven by
  national standards.
• Develops an intelligent tutoring system that has
  the capacity to (a) create authentic multimedia
  scenarios for self-directed, hands-on learning
  and (b) monitor a students performance and
  modify pedagogical strategies based on a dynamic
  assessment of the learner.
• Disseminates results to science and educational
  communities.

19
The Modules

• Crime Investigation
• Origins of Man

This entry triggers placement of suspects
picture on the whiteboard and also brings
related evidence collected up to that time onto
white board and time line

Scientific Reasoning Tool
23
Evidence Gathering and Interpretation Tools

• Data collection notebook on students virtual PDA
• Lab submission forms for analysis
• of evidence in lab (forms located on
  students virtual PDA)
• Students identification of potential subject
• puts relevant information on White Board
  and
• Time Line.

Things We Consider

• Audience
• Advisory Committee
• Content
• Scenario
• Effectiveness
• How to Push the Envelope

25
In Conclusion

• We develop intelligent, interactive, multimedia
  software for educational purposes.
• We make use of advisory committees, focus groups
  and consultants.
• We test and evaluate the software.
