Concept Mapping the Alternation of Generations in Angiosperms

Written by Kelly A. Hogan, University of North Carolina at Chapel Hill

Learning Outcomes:

– To use the words associated with angiosperm reproduction and connect their meaning

– To collaborate with peers on concept mapping

Activity Description: Students are given a list of words they can concept map in small groups. Depending on class size, the concept map can be done in a variety of ways (sticky notes on whiteboards or drawn on paper). After constructing their own concept map, they should examine at least one other group’s map and provide feedback.

Time Needed: 15 minutes

Materials Needed: Blank paper or whiteboards and sticky notes

Activity Instructions: Provide students with the list of words below. Customize the list to fit your teaching. If teaching in a large lecture hall, have the students draw a concept map (in pencil to allow for changes). If in a smaller room with several whiteboards, consider having groups come to the whiteboards with the words on sticky notes. Let them stick the notes and write words too.

If you are not familiar with concept maps, you can read more at:

I suggest allowing your students the freedom to connect the words in ways that allow them to think and not get bogged down with rules. You might want to show them one or two examples of concept maps first to show them the idea. See the attached example.

For an online course or a high technology way of constructing concept maps, you might try an online collaboration concept mapping tool, such as http://cmap.ihmc.us/.

Give students this list of words:

Mature sporophyte

Microspores

Female gametophyte

Haploid

Megaspores

Eggs

Fertilization

Diploid

Meiosis in anther

Sperm

Meiosis in ovary

Zygote

Mitosis

The concept map illustrated here is one example of what a student might produce.
