Knowledge Synthesis: Systematic & Scoping Reviews

Planning a review

Successful knowledge syntheses start with a strong foundation. Before diving in, take time to clarify your research question, explore whether similar reviews already exist, and decide which synthesis method best suits your needs. Consider who should be involved in the process — from subject experts to librarians — and outline a protocol that clearly defines your objectives, methods, and criteria. Thoughtful planning at the outset helps ensure your review is efficient, transparent, and produces meaningful, reliable results.

 

Choosing Your Path: Coursework, Thesis/Dissertation, or Publication

Here’s a breakdown of how a knowledge synthesis aligns with different academic contexts:

 

1. Coursework
  • Defined broadly as assignments performed to support learning in academic settings—ranging from essays and term papers to literature reviews and possibly even systematic reviews 

  • For coursework, knowledge synthesis might be part of a graded assignment but isn't typically meant to contribute new knowledge—it’s more about demonstrating understanding and analytical skills.

 
2. Thesis or Dissertation
  • A thesis (often for Master’s) or dissertation (often for PhD) is a substantial academic document involving original research or comprehensive synthesis to satisfy degree requirements

  • While knowledge synthesis (like systematic reviews or meta-analyses) can be included within these works, relying solely on synthesis may not meet the requirement for original contribution, especially at the doctoral level

  • Doctoral programs sometimes permit a "thesis by publication", where original, peer-reviewed articles are compiled alongside an integrative narrative

 
3. Planning to Publish

 

Common Mistakes in Systematic Reviews

Common problems in approaches to systematic review methods include:

  • Searches that fail to use appropriate keywords and controlled vocabulary
  • Searches that omit key databases
  • Poorly documented searches that are not replicable
  • Failure to develop a robust protocol in advance of beginning searches or abstract review
  • Failure to engage librarian experts in search development
  • Lack of peer review for search strategies
  • Lack of dual review and an adjudication plan for title/abstract and full-text review
  • Lack of justification for limits used in searching
  • Lack of an advance plan for data extraction and review of articles for quality/bias
  • Insufficient team member expertise on the topic of the review (such as when assigned to students)
  • Unrealistic project timelines
  • General failure to follow standards in methods and reporting
