Every rubric in the country lists some form of “Well-Structured Lesson” as an element of successful teaching. But what does that mean? The core is four elements that actually need one another for the lesson to achieve the results we want. That is why in the diagram attached we show them as four intersecting circles. There are intimate connections between these four elements of well-structured lessons as well as the alignment of the activity with the objective.   Therefore it can be futile to study any one of them in isolation without integrating what we learn about all five. What we present in this article and accompanying video is the meaning of each of the five and then the way in which they affect each other to create that “well-structured lesson”.
