Ah... good question...
Biology, chemistry, environmental science up to degree level and basic IT. But since I haven't seriously taught sciences as yet I will probably look for a position at GCSE level at first. The subjects matter and curriculum are set so it will be easier starting at that level - it's also a shortage subject in both secondary (high school) and adult education.
I can also teach any leisure subject I'm good at and have a reasonable amount of experience in... eg. upgrading or building your own computer and designing and building your own webpage at entry level. Both quite popular subjects over here.
Basically, I have been taught to design and implement a course of teaching based on whatever my subject is, using different teaching methods ie. lecture, discussion, role-play, group work, individual work, practical sessions, demonstrations and assignments, setting homework, etc. that are appropriate to the subject. eg, the course outline, scheme of work and individual lesson plans stating the specific aims and objectives of each, and where it is accredited to ensure that it complies with the requirements set by the internal/external examination board.
To assess the suitability of students for the course and their learning needs (learner support ie dyslexia) by various means, assess their learning style and progress by a variety of methods both accredited and non-accredited. To be able to continuously assess the effectiveness of my own teaching and the effectiveness of the course content, materials and resources. etc, etc, etc.... The teaching course is the same regardless of your subject.
This is the first stage certificate. The second stage cerficate is more of the same over a year with more observed teaching sessions, and is really designed for those without a degree but occupational skills teaching in industrial settings. But since I do have a degree and I'm already teaching I can bypass it and go straight to the Cert. Ed. But I need a lot more teaching time to do it. I really did this one to see if it was for me and if I was any good at it. And I'm pleased to reply in the affirmative on both counts. I scored the highest possible marks I could get in my observed teaching sessions.
For my own personal assessment, I'm a much more effective teacher now... I've been teaching other people since I was in my early twenties in on the job skills, but I'm now much more organised in my approach and can actively see that the aims and objectives of my teaching are being met.
I think I've finally found my true vocation... teaching adults is quite different in many ways to teaching children and I much prefer it and I'm definately going ahead with the Cert. Ed.
