I introduce mitosis with an inductive lesson using an overhead
projector. I draw a diagram of a cell in prophase at the top and two
cells in prophase at the bottom and challenge the students to figure
out what "must" happen to get from start to finish. With a little
guidance and some false starts they can induce that the chromosomes
must first double, then organize themselves before separating. After
that I give them the stages sequentially. Later I do the same lesson
for meiosis and after figuring out the essentials themselves, there
is much less confusion between the two processes

For a hands on reinforcement, I give pairs of students
