Teachers continually assess as they teach—observing and reflecting on learners’ responses to determine whether the students are reaching the learning objectives. If students struggle or are not challenged enough, teachers consider the possible reasons and adjust their lessons.

Some Practices for Principle 4:

Teachers check student comprehension frequently and adjust instruction according to learner responses.
To teach effectively, teachers need to evaluate what students know and what they do not know, in real time. We do not want to wait until the end of a lesson or the end of a unit to discover that our students have misunderstood a key concept or have incorrectly learned critical vocabulary.

Teachers adjust their talk, the task, or the materials according to learner responses.
If teachers notice student confusion or misunderstanding during a lesson, they make adjustments so that all learners can meet the learning goals. They may vary their oral language input, use home language or alternative texts, present visual aids, or arrange peer support. They might adapt a task by adding more time, finding supplemental resources, or pulling a small group of students together for reteaching.
