Problem: You're teaching the concept of "arthropod" (insects, spiders, lobsters, crabs, shrimp, etc.) to your fourth-grade students. Using your understanding of DAP as a basis for your decision, decide what the best way to introduce this topic would be - bring in a lobster from a fish store, show a movie showing a "crabber" catching crabs in a crab plot, provide a color picture of a shrimp swimming in the water, or hand out a picture showing insects and their body parts. Justify your choice using your advanced understandings of constructivism and cognitive theory and theorists.
