Check the meaning of the word reliable. I don’t think that is the one you want to use. Reliable means, in this context, that your teacher comes to class on time each day. That’s pretty much a given, and not something that is commendable.

It’s great that your teacher is likable, but most teachers would like to think that they are more than just a buddy to the kids in the class. They would like to think that the kids actually learned something while they were in that class.

I like your intro, that your teacher came to the class with a smile and an interesting fact that captured a quick response from the students – but how about comments on what happened after that? Did that interesting fact lead in to a memorable lesson? Did you actually learn something? The bit about asking questions of each other sounds more like a ‘getting to know you’ process. This would be far more meaningful to the teacher if you commented on her teaching style and perhaps alluded to one particular thing you learned, especially if it was something that you had been having difficulty with – and what led to the ‘aha!’ moment when you broke through.

Did she leave you with a thirst for learning? Something that you will carry forward to your next year’s class?

This isn’t meant as a putdown, but your question and your paragraph read as though you are seriously looking for help, and if your paragraph had turned up on my desk, those are the comments I would append to it.
