In most classes I get told I don't participate because the "discussion" is just answering the teacher's questions, which I find very boring and not worth putting my hand up for.
But in classes such as RE, History, English, etc, where they want your opinions and stuff, I tend to participate too much. I'm one of the only 5 people saying things in that kind of discussion, because I tend to have a lot of opinions on world issues and the like. There are some people in my classes who don't know even who the current president of the USA is.
Sometimes I put my hand up in class just to come out with some typically pedantic point that nobody really wanted to hear, I've only recently learnt to decide if anyone will seriously care about what I have to say. Like in math class today when one of those word problems involved a commercial jet which had six passengers on it on one flight, I was just unfolding my arms to put my hand up and say that that is a shocking waste of fuel, especially as you can clearly see the effects of global warming on the polar ice caps and glaciers around the world, only then I realised that nobody cares about some logical flaw in a word question, and that I would just make myself sound like a nerd, which, as a new student at this school, I am trying to avoid.
