Which of the following is a lengthy component of teacher failed instruction?

The correct choice highlights the anticipatory set and instructional sequence as a lengthy component of teacher failed instruction. This aspect is crucial because it involves how a teacher engages students in the lesson and the steps taken during instruction to guide them through learning.

The anticipatory set serves as a way to activate prior knowledge and capture students' interest, setting the stage for new content. The instructional sequence consists of the specific steps a teacher takes to deliver the lesson content, which can include modeling, guided practice, independent practice, and feedback. If these components are poorly designed or executed, they can significantly impact the effectiveness of the instruction.

In contrast, the other options do not encompass such comprehensive elements of failed instruction. Focusing solely on assessment methods does not address the broader instructional practices that may contribute to student misunderstanding. Likewise, closure of the lesson is important for reinforcing learning, but it is often shorter and less complex than the full instructional sequence. Finally, while types of resources are necessary for teaching, they do not inherently affect the instructional strategy's effectiveness in the same way that the planning and implementation of lessons do.
