Very well put together course: well researched, well prepared, well delivered. A course that can be trusted to yield results when applied in practice, and therefore a much needed and valuable tool to implement with learners who are in danger of failing to learn adequately.
Before the workshop I thought (that) I knew how to teach or introduce my lessons, but now I know that I was not doing justice to my learners. I took them for granted ... as if (they would) very easily understand my instructions.
