Synthesis is about taking the information you've gathered and figuring out what you can do with it. Can it be used to answer a research question? Fix a problem? Bring new understanding of an issue? Offer a solution? Pursuade an listener/reader? Entertain? Motivate?
The chart pictured below includes thinking questions and "stems." Choose the questions and stems that are appropriate for your research purpose.
About this chart: It is a general chart, so not all sections, questions or stems apply to every research type or purpose or they may apply differently. For example, the question, about conditions, restrictions, limitations or obstacles would be answered differently if the research were a stylistic analysis of a particular author's work, as opposed to research on the benefits of different ways of treating a particular illness:
Stylistic research:
the question about conditions may not apply, however, there may be:
restrictions: in the sense that the analysis only applies to the author's early works
limitations: in the sense that some of the author's early works no longer exist
obstacles: in that there is a question about the authorship of some of the works attributed to the author
So, conclusions about the author's early style would have to be presented with this contextual information so that the reader understands that the findings are somewhat tentative: reasonable, but based on mimimal evidence.
Treatment options:
conditions: some of the available treatments are still experimental
restrictions: some may only be available to patients with a very specific set of symptoms and medical history
limitations: some of the studies of the treatments will be ending within the next 6 months so the treatment may no longer be available or may become quite costly
obstacles: the cost of the non-experimental treatments is quite significant
So, conclusions about what course of action to pursue would need to take these issues into account.
