Assessment is not just about measuring what students know; it is about helping them learn more effectively. |
Essential Elements of Well-Structured Lessons
We have treated each element and its skill set separately in other chapters so that we could go into detail here about how they work together. The point we want to make here is that these four elements need one another for a lesson to be seen as complete—to be excellent. And if all four are present in some way, each one needs to be executed well, not superficially or partially.

The primary purpose of assessment is to increase student achievement, not simply to measure it. |
Good assessment practices involve students as partners in their own learning. |
