assessment, diagnosis, and evaluation
Data driven instruction plays a crucial role in effective teaching. An assessment that has no effect on instruction is useless. Assessment can be a valuable tool in deciphering students' proficiencies and difficulties. Educators can use this information to plan, evaluate, and revise instruction that meets the needs of all students. It is important to select an array of formal and informal assessments that directly relate to student learning and can guide instruction. One assessment will not fit all students' learning styles and stages of development. Assessment data can also be valuable in communicating student progress to parents and collaborating with colleagues.
