Solutions: Does experimentation contributes to meaningful learning?
We present a didactic strategy designed in order to investigate if the achievement of a simple laboratory practice, next to the daily reality of the pupil, might help to diminish the difficulties presented by pupils of a first university course of chemistry in the comprehension of the concepts assoc...
