Contents of this talk

Developed a system “AirTransNote”Realizing our “Augmented Classroom” concept

with advanced technologies

Applied for Geometry lectureDynamic reproducing of student note will facili

ate retrospective and reflective thinking

Conventional Classrooms

How to fluidly introduce interactive learning environment into conventional classrooms?

Our solution : Using Paper and Digital Pen

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

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

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

(4) PDA transmits the data via wavelan

　ATN Browser (Shared View)

Outline of AirTransNoteBasic Functions ：

Capture students’ note and transmitTeacher can show the note with projector

• Reduce times to re-write on BlackboardPurpose ：

Facilitate communication between class members

Encourage active learning

A successor of response analyzer (ex. EduClick[Huang 2001])

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

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

Experimental LecturePurpose

Investigate effect of immediate handwriting sharing & reproducing on students learning

Topic of CourseTrigonometric functions (sin,cos,tan) Introduce the definition over 90 degrees

Participants40 Highschool students (15-16 years old)23 with ATN / 17 without ATN

Topic of Course Introduce definition of trigonometric functio

ns over 90 degreesStudents had learned for 0-90 degrees

θ<90θ> 90

Procedures1. Students were asked to try to draw a triangl

e of 120 degrees (with right angle)2. Teacher introduced definition of trigonometri

c func. over 90 degrees.3. Students were asked to draw lines which m

ake angles of 225, 510, -1000 degrees respectively

4. Teacher showed the students’ responces (with animated reproducing)

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

Findings from ObservationTwo notable phenomena

(1) Detailed process could be recognizedSome pen movements briefly stopped every 180

degrees (on x-axis)

(2) A Student focused on other students’ process, and compared with their activities“I first drew the angle line, then

convolutions”

Comments and Feelings from Pen-Used Students80% 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 controversialUneasy/ashamed for wrong answersDepends on atmosphere of class?

Conclusion

Introduced system for instant sharing of student note in Geometry Lecture

Dynamic reproducing of student note will facilitateRecall their thinking processReflection based on objective viewComparison their own process with others

System ImprovementUltrasonic pen ⇒ Anoto pen

Stable transmission of 40 students note via Bluetooth connection
