Final answer:
Sequencing is the learning factor that involves progressing through educational material in a logical order, which ensures a student understands each concept before advancing to more complex lessons.
Step-by-step explanation:
Ensuring a student understands a certain topic before proceeding to a new more complex lesson is an example of the learning factor known as sequencing. This educational concept involves the logical progression of learning where information is presented in an order that builds upon what has already been learned. By confirming understanding before moving on, students are more likely to construct a solid foundation of knowledge, which is essential for mastering more advanced materials.
