Our teachers work according these golden rules:
Don't spend time on activities that students can do by themselves at home.
Be committed and encouraging
Ensure that each student learns as much as possible.
Ensure that each student speaks as much as possible.
Provide individual feedback to each student, identifying specific strengths and weaknesses.
Ensure that individual learners are not held back by the group.
Be clear about what is done in class and what should be done at home.
