At the end of my cells unit (after teaching organelles, membranes, and cellular energy) I would teach mitosis. The more I thought about it, the more sense it made. When we got to the cells unit one of my colleagues suggested only teaching mitosis, and waiting to teach meiosis until we got to the genetics unit. I needed to do something differently.Īfter teaching middle school for 5 years, I switched to a high school near my house. But when I would give the unit test, it was clear the students still confused the two. I would begin by teaching them both separately, and then had worksheets and activities that compared the two. During my cells unit I would teach both mitosis and meiosis. One comment I frequently hear from biology teachers is “My students keep mixing up mitosis and meiosis.” I had this problem for many years (the first 5 years of teaching to be exact).
