The final part of the course involved some micro teaching and a discussion/reflection on the experience.
The students did well and I learned a great deal about their subjects from this, which suggests their communication and teaching skills were effective. However, one of the students told me how worried she was that some of her students would judge her English skills unfavourably compared to the English teachers in her university. It seems that perhaps she is too perfectionist and her teaching of the content in an effective way should be the priority (but perhaps it is easier for me to say this than it is for her to feel this).
Thinking about these teachers, they are under a great deal of pressure. Like most other lecturers, they are expected to be research active and publish, teach their content effectively and do this in a second language. They will need great qualities and strengths but I think and hope they have those qualities.
