It's hard to say whats good and bad when it comes to teaching...I know that we all hated the way out Modern History teacher taught us in year 11 and 12, because she didn't follow the syllabus and spoon-feed us information like all our other teachers did. She taught us heaps of different aspects that weren't a part of the syllabus, and just expected us to actually use some initiative and prepare for exams ourselves, through our own research, and we never really knew if we were doing things "the right way", or not. We were always miles behind, and there was heaps of things that we simply did not get around to in class.
Had she actually had gone through the syllabus points and told us exactly we needed to know and left it at that, we probably all could have done a lot better in the HSC. But I think I would also understand and appreciate what we learned a lot less. So-was she a good teacher, or a bad teacher? At first I couldn't stand her teaching the way she did, and maybe it really wasn't up to her to decide to go off on tangents like that, but I think she was the best high school teacher I had, even if I didn't do too crash-hot in history.
