outline
Outline
  • “Augmented Classroom” project
    • System “AirTransNote”
  • What is “AirTransNote” ?
  • What was lacking for “learning support system”?
  • How we changed the system?
    • What’s the typical usage in lecture?
what is airtransnote
What is “AirTransNote”
  • Devices: Digital Pen and PDA(WLAN)
  • Capture student’s handwritten note on paper, and transmit to teacher’s PC immediately
  • Share by Projecting
  • Store, Analyze, and Review the note
  • Student can get feedback via PDA
atn mediator student

(4) PDA transmits the data via wavelan

(3) The data is sent to PDA via infrared connection

ATN Mediator (student)

(2) The sensors detect theultrasonic waves, and calculateposition data of the pen tip

(1) Tap the pen tip on the paper, ultrasonicwave is diffused

purpose of airtransnote
Purpose of AirTransNote
  • Basic Functions:
    • Capture students’ note and transmit
    • Teacher can show the note with projector
      • Reduce times to re-write on Blackboard
  • Purpose:
    • Facilitate communication between class members
    • Encourage active learning
    • A successor of response analyzer (ex. EduClick[Huang 2001])
our concept augmented classroom
Our concept: “Augmented Classroom”
  • Enhance the ability of classroom with calm technology
    • Based on ubiquitous/pervasive computing paradigm
    • KBD,Mouse→Paper and Pen, RFID
  • However, we should focus on “learning effects” of the system
re design of airtransnote with consideration of learning
Re-design of AirTransNotewith consideration of learning
  • Feedback/interaction is the key factor
    • Shift to “Collaborative learning”
  • Limitation of feedback with paper-centered approach
    • Make full use of PDA for giving feedback
    • Complementary use PDA and Paper
  • →Improve the system to cover the shortages

four learning effects enhanced by airtransnote1
Four learning effects enhanced by AirTransNote
  • Self reflection by student
    • Re-check note on PDA
  • Interaction b/w system⇔student
    • Feedback depends on student response
  • Interaction b/w teacher⇔student
    • Recognition of student’s progress and learning status
  • Interaction among students
    • Sharing/Browsing notes with PDA
      • Tagging/Annotating
system improvenents
System improvenents
  • Previewing with paper image context on PDA
    • Ease of checking
  • Connect with handwriting recognition engine
    • Support for various responces
  • Feedback editor for teacher
  • We attached web server to teacher’s system
    • For checking progress (by teacher)
    • For browsing student note images (by teacher/student)
advantages of digitized note
Advantages of Digitized note
  • △ Show idea with note drawing
      • We can use document camera
  • ○ Capture drawing alone
    • Flexiblity of showing (ex. overlap to compare)
  • ○ Capture time series of note
    • Reproducing note with writing order
      • Ex. Check order of Chinese character
      • Ex2. Show direction of electric current flow (電流方向)
    • Writing order may reflect thinking process
finding
Finding
  • Realtime feedback is accepted by student
  • Feedback may alleviate stress
    • Student can know whether his/her answer is correct or wrong before making public.
  • Further experiment is required
conclusion
Conclusion
  • Re-design of AirTransNote
    • System for facilitating communication in lecture
    • Improved to support “collaborative learning”
  • Future work:
    • Conduct experiment to check “active learning mind” with various conditions
