I believe that the Understanding by Design framework marks a significant shift in the teaching mentality. During Elementary School, my teachers would all too often focus on smaller concepts, often testing objective facts, instead of encouraging students to think about greater concepts to generate more significant understanding. I personally believe that teachers must be mindful that testing of facts does not necessarily equate to knowledge acquisition. Today, teachers have a responsibility to encourage students to think for themselves, and formulate their own meaningful understandings, which can be achieved via: creating flexible, positive learning environments, extensive planning, providing rich opportunities to learn in a variety of ways, and focusing on the big ideas in the curriculum.
