P789: Teaching the mole concept with your mouth shut!
Henry Bent wrote “Should the mole concept be X-rated?” He answered, “Yes! It is annihilating interest in chemistry.” Most chemistry students would agree! The high attrition in first year chemistry courses may partly be attributed to students’ challenges with the mole concept. Those who grasp the mole concept can progress better in chemistry. The literature is ripe with approaches to teaching the mole concept so as not to frustrate the learner. Clearly teaching the mole concept is a daunting task! Who among us have not tried multiple approaches and even been frustrated with the results? Should the mole concept be X-rated? Or could it be taught effectively with our mouths shut? Yes! Provided that students could connect the mole concept with knowledge from everyday experiences. Is there such a connection? I will share my experience of teaching the mole concept with my mouth shut and possible evidence for its effectiveness.
