Whitelock & Jelfs (2003) opened a journal special issue on this topic with three definitions:1. the integrated combination of traditional learning with web-based online approaches (drawingon the work of Harrison);2. the combination of media and tools employed in an e-learning environment; and3. the combination of a number of pedagogic approaches, irrespective of learning technology use(drawing on the work of Driscoll).

Another approach, however, can dramatically impact the effectiveness of blended learning professional development.

In any case, allowing students to express their opinions in the margins of the Web, and helping them become responsible and thoughtful in those expressions, is a huge part of what it means to be literate both on the Web and in democratic society more generally.
