Synthesising: self-assessment

Have you ever received feedback on your writing that says things like:

Your written work reads like a list of studies.
How do the findings by X relate to the findings by Y?
The connections between the different studies you cited are not clear.
You summarised several studies in this paragraph, but what are you trying to say?
You need to synthesise all this data.

If that is the case, then you will find this lesson on synthesising very useful.
