Advantages Approach allows designing
teaching units that place the child in the role of a scientist
Eliminates delay between theory and practice
Teaching unit takes on the role of a guide
Enables topics to be introduced to a younger age group

Learnings Performance does not seem be
affected by background gender previous experience exposure to computers
Transferred learning mass seems high

NIIT IWALT 2000 14
Learnings Quick creation of lessons
possible Can be integrated with non-
formal curricula Computer will have to be placed
in the lab or vice versa New methodology for lesson
design

Future Lessons designed by
children/teachers New experiments conceived by
children New instruments conceived by
children
