The Problem
No seamless connection
amongst
Computer-Based Training Packages - access to only theory
Data-logging units - no access to theory
Lab equipment The Problem

The Solution
Integrate lessons, data loggers
and lab equipment
NIIT IWALT 2000 4
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
NIIT IWALT 2000 5
Lesson Design
Observe phenomenon using the Sensor-enabled system
Postulate appropriate Law/Hypothesis
Do more experiments to verify/validate proposed
Law/Hypothesis
Is Law/Hypothesis postulated correct?
Refer to Current Theory

Learnings
Performance does not seem be
affected by
background
gender
previous experience
exposure to computers
Transferred learning mass
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
NIIT IWALT 2000 15
Future
Lessons designed by
children/teachers
New experiments conceived by
children
New instruments conceived by
