The classroom

The room the tradition built for study before it built a desk, the academy on its axis with the master’s seat on the north wall and the library where the ground rises; the modern classroom read the same way, the windows on the pupils’ left, the teacher in command, the door at the front and the board across the light; what the classroom research found, the daylight study of twenty-one thousand pupils and the survey that put a sixth of a year’s progress down to the room; and the seat in the middle of the front rows that asks the questions.

The student’s desk guide gives one child at one desk, and this one gives the room with twenty-five in it. The tradition built rooms for study long before it wrote about desks: the academy, shuyuan, was a compound on an axis with the master’s seat on the north wall of the lecture hall and the library at the back where the ground rose, and its plan is the courtyard house of the houses essay with a school in it. The modern classroom, read the same way, has its windows along the pupils’ left, its teacher in the command position and its door at the front, and the classroom research, which has measured more rooms than any other branch of the field, finds the same plan from the other end. This guide gives both, the academy on its axis and the classroom on its plan, with what the research found and the one seat in the room that asks the questions.

The academy on its axis

1The gate on the axis, facing south, with the half-moon pool before it
2The first court, open, the students’ rooms along both sides
3The lecture hall across the axis, the master’s seat on its north wall
4The second court and the shrine to the master, or to Confucius, behind the hall
5The library at the back, two storeys, where the ground rises
6The kitchen and the stores off the axis, at the side

Plan 01 An academy on its axis A Confucian academy, shuyuan, of the kind founded from the Song to the Qing and surveyed by Knapp, drawn as a plan of relations and not of one place. Everything stands on one axis running north from the gate. The gate faces south with a half-moon pool before it, which the manuals prescribed for schools as for temples: still water at the front, the bright hall in a wall. The first court is open, with the students’ rooms in ranges along both sides, so that every room looks onto the court and none onto the outside. The lecture hall stands across the axis, its doors open to the court and the master’s seat on its north wall, which is the command position given to the teacher: the wall behind, the whole hall and the court in view, the students facing the master and the light from both sides. The second court holds the shrine to the academy’s founder or to Confucius, and the library stands at the back, two storeys, on the highest ground, which the tradition read as the tortoise behind the compound and the librarians read as the driest place for paper. The kitchen and the stores are off the axis, at the side, as in a house.

The academies were founded from the Song onward as places of study outside the state schools, and Knapp’s surveys of the ones that survive, from Yuelu at Changsha to the small county academies of the south, find one plan under all of them, the plan the drawing above gives as a diagram of relations. Everything stands on an axis running north from a gate that faces south. Before the gate a half-moon pool, which the manuals prescribed for a school as for a temple, still water at the front and the bright hall framed in a wall. Inside, a first court with the students’ rooms in ranges along both sides, every door onto the court and none onto the outside, which is the compound’s rule for its wings. Across the axis the lecture hall, its doors open to the court and the master’s seat on its north wall: the command position given to the teacher, the wall behind him, the whole hall and the court in view, the students facing north toward him and the light from the two sides, which is the arrangement Elman’s history of the examinations finds in the academies’ own regulations, where the seating was ranked and the master faced south as an emperor did. A second court holds the shrine, to Confucius or to the academy’s founder, and at the back, on the highest ground, the library, two storeys, which the tradition read as the compound’s tortoise and the librarians read as the driest place for paper. The kitchen and the stores stand off the axis at the side, as in a house. It is a house with a hall for teaching where the family’s hall would be, and a scholar who had grown up in a courtyard house found nothing in it he did not know.

The classroom, read

1The windows along the pupils’ left, high sills, blinds that cut the glare and not the light
2The teacher’s desk in the front corner, the wall behind, the door and every seat in view
3The door at the front on the corridor side, opening away from the board
4The board on the front wall, across the light; the wall around it plain
5The action zone, front and centre, where the questions are asked and answered; the seats rotated through it
6The pupils’ work on the back and side walls, the plants at the window

Plan 02 A classroom, read by both traditions A classroom of nine metres by seven for twenty-five pupils, drawn as the tradition and the classroom research would both have it. The windows run along the pupils’ left, so that a right-handed writer’s hand does not shadow the page, with sills high enough to keep the desks out of the street and blinds that cut the glare without cutting the light. The teacher’s desk stands in the front corner on the window side, the command position given to the one adult in the room: the wall behind, the door and every seat in view, the light from the side. The door is at the front on the corridor side and opens away from the board, so that a late pupil enters behind no one’s back but the teacher’s. The board is on the front wall, across the light and not against the window, where it would be a silhouette. The rows hold the action zone, front and centre, the seats that ask and answer most, which the classroom studies found and the site suggests rotating pupils through. The pupils’ own work goes on the back and side walls and the plants at the window; the front wall is kept plain, since the research finds the busy wall behind the board costs attention. Nothing on the plan is a cure; it is the students’ desk guide multiplied by twenty-five.

The classroom in the plan above is nine metres by seven for twenty-five pupils, and it is read by the tradition and the research at once, which is the guide’s method. The windows run along the pupils’ left, the tradition’s side light for the scholar and the schoolmaster’s rule for a right-handed writer whose hand would shadow the page from the right; the sills are high enough to keep the desks out of the street and the blinds cut the glare without cutting the light. The teacher’s desk stands in the front corner on the window side, in the command position: the wall behind, the door and every seat in view, the light from the side, which is the master’s seat on the north wall with the compass dropped. The door is at the front on the corridor side and opens away from the board, so that a pupil who comes in late comes in behind no one’s back but the teacher’s, which the doors inside guide would ask of any door onto a room of seated people. The board is on the front wall across the light, never on the window wall, where a teacher becomes a silhouette and a board a sheet of glare. The rows hold the action zone, the seats front and centre from which most of a lesson’s questions are asked and answered, which Adams and Biddle found on videotape in 1970 and later observation has largely borne out, and the site’s suggestion is the schoolmaster’s, to rotate the class through it. The pupils’ own work goes on the back and side walls, the plants at the window, and the front wall is kept plain, since the research finds the busy wall behind the board costs attention. The air guide’s rule closes the plan: twenty-five people in sixty square metres raise the carbon dioxide past the thousand parts per million at which Allen’s subjects thought worse within an hour, and a window opened at each break is the cheapest thing on the page.

Evidence · What the classroom research found

Two studies carry the plan. The Heschong Mahone daylighting study of 1999 followed twenty-one thousand pupils in three American districts for a year and found the children in the classrooms with the most daylight progressing faster in reading and mathematics than those in the least, by a margin the report put at fifteen to twenty per cent; the rooms that did best had daylight from the side and glare controlled, which is the plan above. The margin was largest in one of the three districts, and later work by the same group and in other districts did not reproduce it as cleanly, which is why the site treats a daylit classroom as well supported and not as settled. Barrett, Davies, Zhang and Barrett’s survey of 2015 measured a hundred and fifty-three classrooms in twenty-seven British schools against the progress of nearly four thousand pupils and found the room accounting, in their model, for about a sixth of the variation in a year’s learning, with light, air and temperature the largest part of it, the pupils’ sense of ownership of the room the next, and the room’s visual complexity the last, with the best rooms neither bare nor busy. Neither study is about feng shui and both are about the tradition’s scholar: the light from the side, the air, and a room that is the students’ own and not a gallery.

Design observation · Clusters, rows and the U

A designer choosing between rows, clusters and a U has the same research and a plain answer from it. Rows put the most pupils in the action zone and the fewest with their backs to the teacher, and suit instruction; clusters put a third of the class with its back to the board and suit group work; the U puts everyone in view and no one behind another, and suits discussion, at the cost of floor. The tradition’s reading is the command position multiplied: whatever the arrangement, no child should sit with the door behind them and the teacher out of sight, and a desk that faces the window faces the glare. The plan’s answer is rows that can be pushed into clusters in a minute, which is what Barrett’s survey called flexibility and found worth having.

The seat that asks the questions

The one finding of the classroom research that has no counterpart in the tradition is the action zone, and it deserves its own section because a teacher can act on it tomorrow. Adams and Biddle put cameras in classrooms in 1970 and counted who spoke: most of the exchanges between the teacher and the class came from the front rows and the centre column, a T-shape of seats in front of the desk, and the pupils outside it, at the back and along the sides, asked less, answered less and were called on less, whether or not they knew the answer. Observational work since has kept finding the zone, and the reasons are plain in the plan: the seats in it are the ones the teacher sees without turning, the ones close enough for an ordinary voice, the ones a glance reaches. The tradition would recognise the geometry, since the seats in the zone are the ones in the master’s field of view from the north wall, the near half of the sofa guide’s social band, and the pupils outside it are in the far band with a desk between. What the finding asks of a teacher is not a plan but a habit: to rotate the class through the zone by the week, so that every child spends a fifth of the term in the seats that speak; to walk, since a teacher who moves carries the zone with them; and to seat the child who never speaks in the zone and not at the back, where the quiet ones are usually put and stay quiet. A school that builds the plan above has put the light, the air and the sightlines where the research found them mattering; a teacher who rotates the seats has given every child the seat.

The classroom, in order

The windows. Along the pupils’ left, high sills, blinds against glare and not against light.
The teacher. In the front corner on the window side, the wall behind, the door and every seat in view.
The door. At the front on the corridor side, opening away from the board.
The board. On the front wall across the light; the wall around it plain.
The seats. Rows for instruction, clusters for work, the U for talk; the class rotated through the action zone.
The walls. The pupils’ work at the back and the sides; the room theirs, and neither bare nor busy.
The air. A window opened at every break; twenty-five people fill sixty square metres in an hour.
