classroom curiousity...

In class you always have a variety of characters. Students who are as different as they are many. you might find in your class a student who like to frown. Yes to frown. For no good reason they just push their brows together and stare at the board, you would be forgiven for thinking that aliens are growing from the wall. When i ask then what seems to be the problem is they just go silent for a while then an ohh I got it now is given.

however i prefer those  any day over the curious bunch. Last week while we were discussing rotation, a point on direction of rotation came up and clockwise was given as the negative direction and vise versa. There was a murmur among the curious bunch... then hand up so why is anticlockwise positive and clockwise negative ? my first instinct was to ask them why is '+' addition and '-' subtraction...but that would have been in bad taste, therefore i took a protractor and explained that the degrees increase from 0 to 180 in the anticlockwise direction hence positive direction..
