The ability to break a concept into its similar and dissimilar characteristics

allows students to understand (and often solve) complex problems by

analyzing them in a more simple way. Teachers can either directly present

similarities and differences, accompanied by deep discussion and inquiry, or

simply ask students to identify similarities and differences on their own.

While teacher-directed activities focus on identifying specific items, student directed

activities encourage variation and broaden understanding, research

shows. Research also notes that graphic forms are a good way to represent

similarities and differences.

Applications:

* Use Venn diagrams or charts to compare and classify items.

* Engage students in comparing, classifying, and creating

metaphors and analogies.
