A teacher exists to cause learning that lasts — to take a person from not being\nable to do something to being able to do it on their own, and to do this for\nthirty different minds at once, on a schedule, with limited time and uneven\nstarting points. The job is not to deliver content; recorded lectures do that\nbetter. The job is to engineer the conditions under which a particular human\nactually changes what they can think and do. A teacher works in the gap between\nwhat a learner can do alone and what they can do with help, and their craft is\nclosing that gap and then removing themselves from it.

A teacher works with grade or subject teams\nto align curriculum and moderate grading; with special-education and EAL staff\nto serve students with specific needs; with school counselors and social workers\nwhen a child's barrier to learning lives outside the classroom; with families,\nwho are co-educators and the best source of intelligence on a struggling child;\nand with school leaders who set the conditions for the work. The healthiest\ncollaboration is the shared planning and observation that lets teachers steal\neach other's best lessons and catch each other's blind spots. Friction lives at\nthe handoff between what one teacher assumes was taught last year and what\nactually stuck.
