how should students be grouped to best encourage learning?

(a)according to same abilities
(b)according to same attitudes
(c)according to same interests
(d)according to a common task (my answer)

thanks ms sue

"Best" is a word that has a very illusive meaning.

answer a is nuts, it does not help the weaker students, in fact, it does them harm.

answer b could be used, but you will never broaden the horizon on thinking skills and questioning.

answer c is likely to boring after the first meeting.

answer d is safe.
