One question I often ask myself is, why is it that students will perform differently despite having the same teacher and sharing a classroom?

Considering the psychological requirements of efficient and effective communication I realize how the Zen saying applies: 'When the student is ready, the master appears'.

The classroom is like a burning tree, watered with fire, and 'its' fruit is 'its' food.

Like an eternally burning tree. Holy grounds.

The only thing these letters prove is that one is good in passing exams. A useful skill, yes, but not the fount of ability that we pretend it is.

Two of the smartest people I have ever known never went to school, never learned to read or write. Yet one of them taught me the basics of mathematics when I was very young.

maybe if they went to school they would have proven that they are 'good in passing exams'.

I am trying to imagine the typical class of 60 students, the sphere needed to hold all those student at 2 rows will surely be too big - thus driving the students further away from @tycho.

to increase access of the students to the teacher we would need a floating transparent writing board, accompanied by a rotating platform in the center of the class.
