amongst
Computer-Based Training
Packages - access to only
theory
 Data-logging units - no access

to theory
 Lab equipment


IWALT 2000

Advantages








NIIT

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
IWALT 2000

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?
Yes

Refer to Current
Theory
