SqSquare - a
collaboration environment for children
|
|
７．テーマ概要
|
|
SqSquare is a
lightweight collaboration environment, which supports various interactive
learning activities in network.
Users are able to
share a broad virtual desktop through the network. In that super desktop,
users freely write texts, draw pictures, import sounds, and develop
scripted morphs. The system also supports printing of the developed
contents in a (real) big poster. For helping interactions, users are able
to use voice-chat interfaces. We suppose up to about 20 users can
simultaneously access the system. It is the typical number of children in a
classroom.
In a classroom,
children are often grouped into small teams for learning activities. In the
group, children discuss ideas, reach some agreements, and express them to
large papers for presentation. And then they are merged again in order to
compare their works and discuss the ideas as a whole. SqSquare strongly
supports this style of learning.
General e-learning
classes assign one PC to one person, and each pupil does the e-learning
individually. It often causes a loss of opportunities that could be great
skill and knowledge development if done in collaboration.
SqSquare will
eliminate the barrier and realize an effective computer-aided learning
environment in a classroom.

This propsal offers a lightweight
collaborative environment for Squeak Etoys that could work very well for
the $100 Laptop Project.

１２．プロジェクト評価
|
|
This is an excellent
piece of work, and required quite a bit of design and technical
construction to make it work. It builds on long held ideas about the need
for fully collaborative constructive environments on the Internet, but
getting most of the details designed, invented and implemented is an
important part of this technology area.
Another
strong point of this research is that the implementation was done strongly
enough to be released for testing with children and for experimentation by
other researchers: it is finished off well enough to be used “out of the
box”, and this use immediately suggests further desirable features. Some of
these are mentioned in the Future Work section of the report.

１３．今後の課題
|
|
The two things that
most need to be done next are to test the design with real-users, especially
children and teachers, and to think more widely about desirable scaling
properties. For example, the $100 laptop will be using a "nearby
village" metaphor to organize collaboration through its mesh network.
If the "village" is not too large then the current SqSquare UI
will probably work. If the village is larger then it is likely that this
design will have to be modified somewhat.
It will
almost certainly be necessary for SqSquare to move to a peer-peer
architecture, especially for the needs of the $100 laptop.
