My teaching style is primarily centred on class engagement. I adapt my teaching style in order to cater for everyone and make the material as interesting as possible.
I like to use group exercises, colorful PowerPoint slides and even videos where possible to demonstrate my learning points. I believe this is something which increases student interest significantly, and from my experience, leads to a better learning experience overall.
I fully understand the pressures that are placed on teachers. And I also understand the pressures placed on you, the school. These pressures need to be managed effectively so that we all work together to achieve the aims of the school and meet the needs of the students we are teaching.
