The job is not to deliver content; recorded lectures do that better. The job is to engineer the conditions under which a particular human actually changes what they can think and do. A teacher works in the gap between what a learner can do alone and what they can do with help, and their craft is closing that gap and then removing themselves from it. - heading: Core Mission markdown: >- Move every student in the room from where they are to a meaningful next step, making the invisible work of thinking visible enough that learning can be guided, checked, and owned by the learner. - heading: Primary Responsibilities markdown: >- The visible work is standing in front of a class; the actual work is design and diagnosis. A teacher plans sequences of lessons that build one idea on the last; writes and runs daily lessons that hold attention and produce evidence of understanding; checks for understanding continuously, not just on the test; gives feedback that a student can act on; manages the social system of a room so learning can happen at all; differentiates so the fast and the struggling both move; assesses fairly and reports honestly; and builds relationships with students and families, because a child who doesn't trust you won't risk being wrong in front of you. Underneath all of it is relentless decision-making: a teacher makes hundreds of micro-decisions an hour about whom to call on, when to wait, what to reteach, and when to move on. - heading: Guiding Principles markdown: >- - **Every student can learn, but not on the same day in the same way.** High expectations are non-negotiable; the path to them is individual. - **You teach students, not subjects.** The content is the vehicle; the child is the destination. - **No learning without retrieval.** Understanding that is only recognized, not recalled, is an illusion. Make them pull it from memory. - **Behavior is communication.** A disruption is data about an unmet need, a gap in skill, or a task pitched wrong — diagnose before you discipline. - **Make the thinking visible.** If you can't see how a student is reasoning, you are teaching blind. - **Relationships are the precondition, not the reward.** Rules work because the relationship makes them matter. - **Plan for the wrong answers.** The misconceptions are more instructive than the right answers; anticipate them. - heading: Mental Models markdown: >- - **The Zone of Proximal Development (Vygotsky).** Teach at the edge of what a student can do with support — too easy bores, too hard defeats. Scaffold, then fade the scaffold. - **Gradual release of responsibility ("I do, we do, you do").** Model it, practice it together, then hand it over. The goal of every scaffold is its own removal. - **Cognitive Load Theory.** Working memory is tiny; novices overload fast. Strip extraneous load, sequence so each step has room, and use worked examples before open problems. - **The forgetting curve and spaced practice.** Memory decays predictably; revisit material at spacing intervals rather than cramming. Interleave topics so retrieval stays effortful. - **Formative vs. summative assessment.** Assessment *for* learning steers the next lesson; assessment *of* learning measures the result. Most checking should be formative and cheap. - **Bloom's taxonomy as a ladder.** Remembering and understanding sit beneath applying, analyzing, evaluating, creating. Don't ask a student to evaluate what they can't yet recall. - **Wait time.** The three seconds of silence after a question is where thinking happens; rushing to fill it teaches students that speed beats depth. - heading: First Principles markdown: >- - Learning is a change in long-term memory; if nothing changed there, nothing was learned. - You cannot pour understanding into a head; the learner has to do the cognitive work themselves. - Attention is the bottleneck — you can only learn what you attend to. - A class is thirty individual trajectories that happen to share a room. - Trust is the currency that buys the risk-taking learning requires. - heading: Questions Experts Constantly Ask markdown: >- - What exactly do I want them to know or be able to do by the end — and how will I know they can? - What does a student have to already understand for this to make sense, and have I checked they do? - What's the most likely misconception here, and how will I surface it? - Who in this room is lost right now, and what's my evidence? - Am I doing the thinking that the students should be doing? - Is this activity producing learning, or just producing busyness? - What's the smallest next step for the student who's stuck? - heading: Decision Frameworks markdown: |- - **Reteach, move on, or differentiate?** If most of the class missed it, reteach differently — the first explanation failed, not the students. If a few missed it, small-group or targeted support. If all got it, move on; over-review is a tax on the ready. - **Backward design (Wiggins & McTighe).** Start from the end: what's the desired understanding, then what evidence proves it, then what learning gets them there. Activities chosen first, goals retrofitted, is how lessons drift. - **The pitch decision.** Set a task hard enough to require thought but accessible enough to start. Aim for roughly an 80% success rate on first practice — high enough to sustain effort, low enough to be worth doing. - **Correct vs. coach.** For a factual slip, correct fast and move. For a reasoning error, slow down and make them find it; the struggle is the lesson. - heading: Workflow markdown: >- 1. **Plan the unit backward.** Define the end goal and the assessment first, then sequence lessons so each builds the prerequisite for the next. 2. **Plan the lesson around an objective.** One clear, checkable goal per lesson; choose the task, anticipate misconceptions, decide the checks for understanding. 3. **Open with retrieval.** Begin by pulling yesterday's and last week's material from memory — a do-now, a quick quiz — to strengthen it and to see who's behind. 4. **Teach in the release cycle.** Model, guided practice, independent practice, checking at each handoff before letting go. 5. **Check continuously.** Cold-call, mini-whiteboards, exit tickets — gather evidence of who understands, not just whether the room nods. 6. **Respond in real time.** Reteach on the spot when the checks say so; the plan serves the learning, not the reverse. 7. **Mark to inform.** Read student work for the patterns, not just the scores; tomorrow's lesson is written by today's errors. 8. **Reflect.** What worked, who's still stuck, what to reteach — adjust the next lesson accordingly. - heading: Common Tradeoffs markdown: >- - **Coverage vs. mastery.** The curriculum is too long for the year; racing to cover it all leaves a class that has heard everything and learned little. Choose the threshold concepts and teach them to depth. - **Whole-class pace vs. individual need.** Teach to the middle and you lose both tails; the craft is structuring the room so you can pull the tails toward the middle. - **Structure vs. autonomy.** Tight structure helps novices and confines experts; release control as competence grows. - **Engagement vs. learning.** A fun activity that produces no retrieval is entertainment. Engagement is necessary but not sufficient. - **Praise vs. honest feedback.** Empty praise feels kind and teaches nothing; specific feedback on the work, not the person, is the kindness that helps. - **Standardization vs. responsiveness.** A scripted lesson is reliable; a responsive one is better when you can read the room well enough to adapt. - heading: Rules of Thumb markdown: >- - If the teacher is working harder than the students, the lesson is backward. - Cold-call, don't take volunteers — volunteers tell you who already knows. - Never ask "Does everyone understand?" — they'll say yes. Ask them to show you. - Show a worked example before you ask for independent work. - Praise the effort and the strategy, not the intelligence. - When the room is loud, lower your voice; when it's restless, change the task. - Name the behavior you want, not the one you're seeing. - One new thing at a time; novices can't juggle. - The student who never causes trouble can be the one you're losing. - heading: Failure Modes markdown: >- - **Teaching the lesson, not the learner.** Marching through the plan while half the room is lost because the plan, not the students, is in charge. - **Mistaking coverage for learning.** "I taught it" is not "they learned it." - **The illusion of fluency.** A class that follows your worked example feels expert; tested cold a week later, they've retained little. Confusing performance during instruction with durable learning. - **Praising compliance over thinking.** Rewarding neat, quiet, on-task behavior and accidentally suppressing the productive struggle that learning requires. - **Reactive discipline.** Escalating with the student instead of de-escalating; winning the battle and losing the relationship. - **Death by worksheet.** Filling time with low-cognitive-load busywork that generates compliance and no learning. - heading: Anti-patterns markdown: >- - **The sage on the stage** — talking for the whole period while students passively receive, then wondering why nothing stuck. - **Round-robin reading / popcorn** — public, anxiety-inducing, low-learning. - **Asking only the hands that go up** — teaching the kids who least need it. - **Grading everything** — drowning in marking that students never read. - **"Any questions?"** as the only check — silence means nothing. - **One-and-done teaching** — covering a topic once and never returning to it. - **Mood-based classroom management** — rules that change with the teacher's day. - heading: Vocabulary markdown: >- - **Scaffolding** — temporary support that lets a learner do what they can't yet do alone, removed as competence grows. - **Formative assessment** — low-stakes checking used to steer instruction. - **Differentiation** — adjusting content, process, or product to student need. - **Retrieval practice** — recalling information from memory to strengthen it. - **Pedagogical content knowledge** — knowing not just the subject but how it's best taught and where learners stumble. - **Misconception** — a coherent but wrong mental model that resists correction. - **Exit ticket** — a quick end-of-lesson check of what was learned. - **Cold call** — naming a student to answer without their volunteering. - **Wait time** — the deliberate pause after a question before taking answers. - heading: Tools markdown: >- - **The lesson plan and the curriculum map** — the architecture of where each lesson sits in a year of learning. - **Mini-whiteboards / response systems** — to make every student's thinking visible at once. - **Visualizers, the board, worked examples** — for modeling thinking step by step. - **Formative checks** — exit tickets, quizzes, hinge questions that decide whether to move on. - **A learning management system / gradebook** — to track progress and communicate with families. - **Seating charts and routines** — the quiet infrastructure that makes a room predictable enough to learn in. - heading: Collaboration markdown: >- Teaching looks solitary and isn't. A teacher works with grade or subject teams to align curriculum and moderate grading; with special-education and EAL staff to serve students with specific needs; with school counselors and social workers when a child's barrier to learning lives outside the classroom; with families, who are co-educators and the best source of intelligence on a struggling child; and with school leaders who set the conditions for the work. The healthiest collaboration is the shared planning and observation that lets teachers steal each other's best lessons and catch each other's blind spots. Friction lives at the handoff between what one teacher assumes was taught last year and what actually stuck. - heading: Ethics markdown: >- A teacher holds a captive audience of minors during the years their habits of mind are forming, which is real power. The duties: hold high expectations for every student regardless of background, because low expectations are a self-fulfilling prophecy; grade by the work, not by the student you like; protect children's safety and report harm; respect family and cultural difference without lowering the bar; keep what students disclose confidential except where safety overrides it; and teach students to think, not what to think — especially on contested questions. The gray zones — how much to push a fragile student, when a family's wishes conflict with a child's interest, how to grade effort against attainment — rarely have clean answers and deserve to be weighed openly. - heading: Scenarios markdown: >- **Half the class bombs the exit ticket.** The lesson on fractions felt smooth — students nodded, the worked example landed, the room was on task. Then the exit ticket comes back and fourteen of twenty-eight got it wrong, all making the same error: adding denominators. The novice reaction is to reteach the same way, louder. The expert reads the error as a misconception — the students are treating denominators like whole numbers — and knows the original explanation reinforced it. Tomorrow opens not with the procedure but with a concrete model (folding paper, area diagrams) that makes "thirds and quarters aren't the same size piece" undeniable, then rebuilds the procedure on top of the corrected mental model. **The disruptive student.** A boy talks over the lesson, distracts his neighbors, and refuses a redirect. The reactive move is to escalate publicly and win. The expert reads behavior as communication: a quiet private check reveals he can't read the board text and is covering embarrassment with noise. The "behavior problem" was an undiagnosed access problem. The fix is a front seat, a printed copy, and a discreet word — and the disruption evaporates because the need behind it was met. **The bored top student.** A girl finishes every task in half the time and has started reading under the desk. Punishing her for being ahead teaches her that school punishes competence. The expert differentiates upward: she gets an extension task that demands genuine analysis, not just more of the same, and is occasionally asked to explain her reasoning aloud, which both stretches her and models thinking for the class. Stretching the top is as much the job as catching the bottom. - heading: Related Occupations markdown: >- A teacher shares the developmental focus of many roles but is defined by causing learning in groups, on a schedule. Special-education teachers do the same work with individualized intensity for students whose learning differs. School counselors handle the social and emotional barriers that block learning. Professors teach but at the frontier of a discipline, to adults who chose the subject. Instructional designers engineer learning without the live room. School principals were usually teachers first and now set the conditions for teaching. Mentors do one-to-one developmental teaching outside any institution. - heading: References markdown: |- - *Understanding by Design* — Wiggins & McTighe - *Make It Stick* — Brown, Roediger & McDaniel - *Teach Like a Champion* — Doug Lemov - *Visible Learning* — John Hattie - *Mind in Society* — Lev Vygotsky - *Why Don't Students Like School?* — Daniel Willingham
