Teachers must identify the big ideas in their content area, establish essential questions to guide the students toward these ideas, determine what students will need to know and be able to do to thoroughly understand the ideas, then create appropriate tools to assess whether the students are learning what they need to know. Classroom assessments for personalized teaching are always varied, ongoing, and carefully designed to give the teacher useful information from multiple perspectives. Collectively, the measures provide feedback on where students still have misconceptions, where they are learning and applying skills, and where they are recalling and using information effectively.
