L’insegnamento della meccanica al biennio della scuola media superiore. Prima parte: la proposta

We propose an unconventional teaching approach to newtonian mechanics at high school level (age 14-15). Force and energy concepts are simultaneously introduced from the very beginning and then developed through the teaching sequence, with increasing levels of differentiation and formalization. First we sketch basic lines of our proposal and then we suggest some experimental works to perform in classroom setting.
