A common problem I observe in student papers the use of source material in a sequential as opposed to an integrated fashion.
For example, the first paragraph will be based on source 1, the second paragraph based on source 2, third paragraph on source 3, etc...
I am having a hard time helping them develop their writing to the point that they integrate their sources into a more fully synthesized argument that is supported by their sources.
To date, I have highlighted the problem in drafts and given them examples of papers where the sources were used effectively but I find that they have a hard time transferring the skill from the examples.
What other approaches would be effective to help the students develop more sophisticated use of source material?
(I teach in biology so the students are most often writing review papers where they use existing biological literature to support a hypothesis.)
