• Background• Introduction to VPB• Why VPB?• Methodology• Results & Analysis• Conclusion• Q & A

3

Problems Faced by Teachers

• Tutorial time is limited.• There is a constant need to re-explain previous

concepts during tutorial.• There is a need to address the learning pace of

students with different learning abilities.

4

Problems Faced by Students

• Students need to hone their question analysis skills.

• Some students need to remember the process of arriving at the final solution.

• Mathematical examples.

5

Introduction to Video Paper Builder (VPB)• Video Paper Builder is a multimedia creation

software▫ Java-based and runs in Mac or Windows

environment.▫ Accepts inputs such as HTML documents, video

and image files.▫ Generates the final published document in HTML

form which can be uploaded to the Internet easily.

6

Why VPB?

• Web-based. Students will be able to access the material anywhere.

• Allows for video-capturing in published product.• Text and slides alongside video aids in

explaining and the understanding of the process flow.

• Sample of a Analytical Skills\index.htm

7

Problems solved by using VPB

• Video recorded is a close substitute of the actual explanation covered during tutorial.

• Student can replay the video repeatedly to help in his understanding.

• Thinking process and analytical skills are demonstrated.

• Thus the process of arriving at the solution is presented to the students.

8

Other technologies involved

• CamStudio – free video capturing software that allows us to capture the video in .avi format

• Delicious.com ▫ a social bookmarking web service for storing,

sharing and discovering web bookmarks.▫ through delicious.com, we believe it will be easier

for students to get access to the links and spread the word.

9

Combining the various technologies

• VPB provides the template for videos and notes.• Cam Studio allows easy capturing of videos from

tablet PCs.• Delicious.com stores the bookmark for easy

access and sharing.

10

Methodology• 9 classes (total of 180 students)• H2 Mathematics topics selected

▫ Binomial Expansion▫ Arithmetic and Geometric Progression▫ Series and Sequences (Method of Differences)

• Rationale for selection of topics

11

Methodology

• Non-randomized pretest-posttest design.• Pre-test is given.• Viewing of video-papers via internet. • Post-test is conducted with questions of similar

standard.• Pre-test and post-test scores are collected and

analyzed.• A survey was also conducted after the whole

exercise.

Conclusion

• More time is spent on explaining difficult concepts during tutorial.

• Tutors did not have to re-explain previous concepts during tutorial but refer students to the videos.

• Students with different learning abilities are able to follow the concepts during the next tutorial.

22

Conclusion

• VPB is effective in helping students to improve their analytical skills.

• Students take responsibility for their own learning.

• Face-to-face interactions with tutors are still important.

23

Areas of Improvements & Applications

• To include subtitles in the videos.

• VPB can be used in other areas of disciplines like Economics and History.

• VPB can be used to collate and compile interesting & useful concepts for future references for students.

24

Areas of Improvements & Applications

• Quality of voice recording can be improved on. • To collect topics of interest selected by the

students for more effective learning.
