I had a discussion with a fellow colleague on the meaning of rigour in classroom teaching last week. He argued that he is striving to have rigour in his teaching by teaching many examples for a single science concept. My point is at the end of the day what has the students understood? Will they recall the specifics or just the overarching principles? Were the students given time to internalise the underlying principles/concept that can explain the many examples given to them? Are we merely teaching to our tests and examinations while students know that they can only play along in order to score good grades?

The post here may enlighten us.
