208 undergraduate students studying in fourth semester of
Graduation in science were divided in two groups based on
their previous achievement marks in previous semester and
their achievement was evaluated by administered Pre test
through an Achievement Test”. For both groups were
allowed to perform the same experiment on photoelectric
effect.
Participants in the First group, designated as control group,
were allowed to conduct experiment under real lab
situations. This group used real apparatus and materials
about “Photoelectric effect” (for example photocell,
rheostat, power supply, ammeter, and voltmeter) in a
conventional physics laboratory
