Dive deeper into mastery with me and my friend Yoda because everything sounds better when Yoda says it! To translate for those that don't speak Yoda: The mind of a child is a truly wonderful thing. This resonates with mastery in the classroom because while each child's mind is truly wonderful, not every mind operates the same, moves at the same pace, understands the same content or processes information the same way. Differentiation comes to mind as we need to meet each student where they are at and meet their individual needs. However, this ideology falls apart when we look at our current system of education.
In the TED Talk, "Let's Teach for Mastery, Not Test Scores," Sal Khan (My 2nd favorite behind Yoda) offers an amazing analogy at building a house in reference to mastery. You would not move to the first floor of building a house if the foundation wasn't fully set. You certainly would not move on to the second story if the foundation wasn't set AND the first floor was only 80% finished.
So why do we move students along when they have not fully mastered the material? I see this very often in our math classes. We lecture, give homework, go over homework the next day, lecture some more, more homework and so on for a few weeks until the assessment is given. If a student has earned an 80% they kind of celebrate - hey I got a B. What about that 20% of material they didn't show mastery on? This is going to rear it's head again. Even the 95% test earner still shows that 5% is unlearned. We are creating educational gaps that will bite these students hard, later on in their schooling. We need to be patient and wait out the curricular demands and pacing schedules and help students master the information before introducing something new.
Sal was speaking directly to me, as he normally does, when he mentions students who experienced learning gaps and attributed them to the "I don't have the math gene" and "I can't learn this" as excuses. This WAS me as a student and then as an adult it all changed when I matured and persevered. I loved mastering math and teaching math to students who feel like they just don't get it!
Now I just wish it wasn't a race the to the finish line!
Patience, you must have. - Yoda
