There are basic, fundamental equations that control things, including classroom activities, so here they are:
This can be proved, because if you give mild jip to a relatively minor teacher (for example, a Ped', a supply etc.), you don't get much in the way of teacher beats, but if you give the same jip to the headmaster, you'll end up with several hours of detention. Probably.
This is true, because control is inversely proportional to Dis, i.e. the more Dis, the less control, and the less Dis, the more control they have over you.
This means that the more control the teacher has, and the less Dis there is, the higher their teaching ability.
But what is Dis? Dis can be measured on a scale from -10 to +10, with negative numbers representing behaviour. This scale might give you some idea of what kind of Dis you are achieving in your lessons.
+10 Teacher gone/incapacitated. All out
anarchy. Serious injury/damage. Dis begins to spread to other
rooms/areas of the school.
+9 Teacher threatening severe punishment, damage
to basic infrastructure of room.
+8 Screams, damage to most objects. Environment
moderately dangerous. People ignore detentions and attempts to be
sent out.
+7 Loud shouting, heavy objects thrown. Organised
dis. Advanced acrobatics.
+6 Blatant dis to teacher's face and noise over
teacher's voice. Projectiles through air. Damage to chairs and
tables. Desk Stands
+5 Lots of loud noises, half the class out of
their seat. Damage to equipment.
+4 No work, regular loud noises, more than five
people out of their seat.
+3 Doing no work. Burts of loud noise. Teacher
getting angry.
+2 Doing very little work, a few people out of
their seats, teacher getting mildy annoyed at the noise
+1 Slight disruptions, some people not
concentrating on work. Idle chatter, few teacher insults.
0 Completely neutral lesson. People neither working or misbehaving, merely doing the minimum necessary to get by uneventfully.
-1 Concentrating on work, staying on
task.
-2 Working well, quiet working environment.
-3 Working co-operatively. Friendly to
teacher.
-4 Actively helping others and teacher.
-5 Offering to stay behind after school, or to
receive extra homework.
-6 Having meaningful and insightful conversation
with teacher - chatting in a friendly way. Working in
silence.
-7 Offering teacher gifts.
-8 Actively worshipping teacher, becoming
sickeningly sycophantic
-9 Actively worshipping teacher and education
system
-10 Co-planning the lesson and/or the rest of the
school.*
* A strange phenomenon occurs here. While co-planning the management of the school might seem the kind of thing that only the most anal retentive stuck up GC would even consider doing, it loops right back round to Level 10 Dis if you are running the school with subversive intent.
The rating are obviously very fuzzy, as you cannot give a proper mathematical definition of an activity, but they're generally pretty accurate. Fractional numbers are perfectly possible. So far, we've achieved about a level 9.5, but that was with a supply teacher, which is cheating a bit.
Science lessons are different, because it is significantly easier to damage objects, as you have access to a greater array of weapons of destruction. Fire can be involved more easily in science lessons, which helps the Dis level a great deal.
