Setting and maintaining expectations are key to professional and productive relationships with students. The expectations must be real and only become vital and meaningful through consequences. These consequences must be proportionate and logical. For example:
A student turns in work that is obviously disorganized and put together at the last minute. An inappropriate response might be to not accept the homework at all. An appropriate response could be a requirement that the student rewrites the assignment neatly, dedicating the time to a quality product.
A teacher should expect the submission of a neat product which is based on sufficient, focus, effort and time. There is no better learning experience than redoing the assignment until the finished product meets these expectations. The student then learns why the expectations are in place and can become proud of their achievement. More to come.
