In online learning every gradable interaction between students and instructors occurs through writing. Recognizing that all students do not show up with either the same, or even adequate writing skills prompted the Academy to institute an online writing “lab.” This lab consists of numerous tutorials in various categories.
Students can use the lab at any time but the significant connection occurs between the course work produced by the student and the tutorials the course instructor suggests after grading the work.
It's easy to understand the continuity built into our educational system. Students learn the alphabet and simple math in their early years and progress through the complexity and depth of these skills as they move through the system. Each stage of the process lays the groundwork for the next. To anyone who thinks about this it seems like a natural progression.
The same type of progression though is not really understood in physical education.
