Abstract

The study involved 12 undergraduate teacher trainees who embarked on several 3-step sequenced laboratory activities to assess how it would affect their conceptual understanding of some analytical chemistry concepts in a conceptual laboratory. A quasi-experimental approach was adopted. Results from the study showed that majority of the trainees preferred engaging in virtual activities more than, and before physical activities. There were improved gains in conception with trainees’ engagement in sequenced experimentation with a Hake’s gain of 0.58.
