Resource MetaData 2

• Class-by-class summaries of information on test
  questions (here PHY183, SS02)

5
One more ..

• Detailed feedback on where students experience
  difficulties
• Opportunity for selective interventions
  individual branching points
• Guy Albertelli, Berhouz Minaei-Bigdoli, William

Open Problem Library

• Large library of problems (we are almost there)
• MetaData record degree of difficulty and
  discrimination for each class, for each problem
• Open to all students for practice
• Let computer pick problems for exams
• No more question Is this on the exam?
• Prof and student are on the same side
• Measure teachers and learners more objectively
• Provides a more reliable measure to evaluate
  teaching innovation
• More objective data for faculty teaching
  evaluation than student response forms

Different Students Learn in Different Ways

• Beyond obvious
• But no significant difference phenomenon
• attempt to measure learning innovation in
  one-size-fits-all mode
• Goal Let students optimize their own learning
  environment by selecting resources that help them
  understand best (talking head, animated
  blackboard, movie of lecture demo, interactive
  applet, series of equations, text and pictures,
  )
• Train computer to recognize choices and tailor
  first offering to perceived needs
• Adaptive learning(Compare Amazon web site)
