  1. AirTransNote:An Instant Note Sharing and Reproducing System to Support Students Learning Motoki MIURASusumu KUNIFUJI Japan Advanced Institute of Science and Technology Yasuyuki SAKAMOTO Senior High School at Sakado, Univercity of Tsukuba

  2. Contents of this talk • Developed a system “AirTransNote” • Realizing our “Augmented Classroom” concept with advanced technologies • Applied for Geometry lecture • Dynamic reproducing of student note will faciliate retrospective and reflective thinking

  3. Conventional Classrooms How to fluidly introduce interactive learning environment into conventional classrooms?

  4. Our solution : Using Paper and Digital Pen

  5. AirTransNote • A computer-mediated collaboration system for conventional classroom • provides real-time note sharing • Note written by students on a paper is transmitted to teacher’s computer • Teacher can browse, show, store and analyze the notes immediately

  6. (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

  7. ATN Browser (Shared View)

  8. Outline 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])

  9. Key Functions of AirTransNote • (1) Dynamic Reproducing of student’s note • (2) Handwritten note recognition and feedback on Students’ PDA • (3) Dynamic note rearrangement by answer

  10. (1) Dynamic Reproducing of note

  11. (2) Handwritten note recognition and Feedback on Students’ PDA

  12. (3) Dynamic note rearrangement by answer

  13. Experimental Lecture • Purpose • Investigate effect of immediate handwriting sharing & reproducing on students learning • Topic of Course • Trigonometric functions (sin,cos,tan) • Introduce the definition over 90 degrees • Participants • 40 Highschool students (15-16 years old) • 23 with ATN / 17 without ATN

  14. Topic of Course • Introduce definition of trigonometric functions over 90 degrees • Students had learned for 0-90 degrees θ> 90 θ<90

  15. Procedures • Students were asked to try to draw a triangle of 120 degrees (with right angle) • Teacher introduced definition of trigonometric func. over 90 degrees. • Students were asked to draw lines which make angles of 225, 510, -1000 degrees respectively • Teacher showed the students’ responces (with animated reproducing)

  16. 実践授業の様子 • 510度の角をとるときに，180度毎にペンを止め，あと何度回せばよいのか考えながら角度を書いている様子がみられた • それを受け，別の生徒の筆記を再生しているあいだに「自分は先に線を引いて，それから角を書いたんだ」という発話があった • 自分と他人の回答プロセスを比べていた • 再生された筆記を見ることで，自己の回答プロセスに対する内省（リフレクション）が起きていた可能性がある

  17. Findings from Observation • Two notable phenomena • (1)Detailed process could be recognized • Some pen movements briefly stopped every 180 degrees (on x-axis) • (2) A Student focused on other students’ process, andcompared with their activities • “I first drew the angle line, thenconvolutions”

  18. Questionnaire result • **Q3: Satisfaction（χ2(3)=11.91, p<.01 ） • * Q5: Activeness （χ2(3)=9.09, p<.05 ） were significantly differed in distributions of ratings (4-point scale)

  19. Comments and Feelings from Pen-Used Students • 80% of students rated positive value • The lecture with pen was fun. • I could actively participate than usual. • I want to take the lecture with pen again. • “Anonymity in publicizing note was controversial • Uneasy/ashamed for wrong answers • Depends on atmosphere of class?

  20. Conclusion • Introduced system for instant sharing of student note in Geometry Lecture • Dynamic reproducing of student note will facilitate • Recall their thinking process • Reflection based on objective view • Comparison their own process with others

  21. System Improvement • Ultrasonic pen ⇒ Anoto pen • Stable transmission of 40 students note via Bluetooth connection • (Digital Pen Gateway System by NTT Comware Corp.)
