Looking up the word 'rapport', I come across the following:
noun [S or U]
a good understanding of someone and an ability to communicate well with them:e.g.
We'd worked together for years and developed a close/good rapport.She has an excellent rapport with her staff.(Cambridge Advanced Learner's Dictionary)
But somehow, this doesn't always seem to work out in the classroom. Dealing with students over roughly eleven years, and based on experiences that other teacher have shared with me, we have to be really quick to understand what makes our students tick and how to bring out the best, not the worst in them.
