BASIC MODEL OF LEARNING
In systems thinking mapping, we use a stock (rectangle) to represent the accumulation of skills and content mastery. Think of this as a bathtub of mastery. The bathtub is filled by an inflow of learning that occurs via curriculum delivered through courses (Figure 1). Every day a student attends school (attendance is an absolute precondition for learning and for many schools absenteeism is a serious problem), presumably she will learn some skills and content that fill up her bathtub of content and skill mastery. But if the student does not have opportunities to apply the skill within a certain period of time after learning it, the likelihood that she will eventually forget the content or skill is high. The outflow in the image below represents the process of content and skill mastery “atrophying” (or being lost) over time (Figure 1).
