When students recognize this, then they understand why Standard English is important and do not resist learning the mechanics that society expects. If we value what students bring with them to the classroom, instead of making judgements about their background or upbringing, we may indeed reach a point where basic skills tests are no longer even a point for discussion. Project based learning, which allows children to write and exchange ideas over the internet for other classes, for other eyes, creates for many children a wish to have more than standard writing, that is expressive, that shares the ideas they wish to exchange, and that hopefully, will provoke replies that are equally as interesting. The work that children do to communicate beyond the classroom, is really motivational. Purposeful writing activities create a desire for better language expression .
