Classroom Strategy

Have your students spend the majority of time completing a script (eg. classroom ideas: http://langwitches.org/blog/2009/10/19/we-podcasted-today-so-did-you-learn-anything/), which can be split up amongst a group. The teacher can then mark this script instead of the podcast itself to generate an individual mark.
