When students are asked to compare and contrast, they open their mind to more firmly defining each topic. They come to understand what the topic is and is not in comparison or contrast with another topic. They engage in higher level thinking.
I watched students list the similarities and differences between two stories they had just read. By looking at their circles I could not see the corresponding differences. When there are two overlapping circles such as for butterfly/moth, students do not identify what is the topic of each difference. I would suggest that students do not use circle Venn diagrams.
I prefer that students use block Venn Diagrams in which differences are clearly contrasted. You can easily make this in Word or Inspiration.
You might even want add a final line on the chart that says “Conclusion or Interpretation.”
Do you have another form of a compare and contrast chart that clearly helps learners to develop in-depth learning?
