Research Literature Reviews: Why?

Why conduct a Literature Review?

A proper literature review is the INTIAL STEP in conducting STEM research.  They serve these purposes:

  • build or refine new hypotheses
  • inform the design of new experiments 
  • provide context for experimental findings

Proficiency in conducting and dissecting literature reviews leads to the following outcomes:

  1. Broadens perspectives by learning the evolution of the research topic and identifying unanswered questions. 
  2. Connects to the core scientific process by making evidence-based claims followed up through a literature review.
  3. Gains experiential learning that research is collaborative in nature across disciplinary boundaries.
  4. Develops skills in retrieving information through effective reading and analysis.
  5. Hones skills in effective writing and communication to share knowledge.

Scenarios for Lit Review Writing

According to Fink (2020),  literature reviews are conducted for the following reasons:

  1. Write proposals/grants for funding
  2. Write proposals for academic degrees
  3. Describe & explain current knowledge to guide professional practice
  4. Identify effective research & development methods
  5. Identify experts to help interpret existing literature & identify unpublished sources of information
  6. Identify funding sources & works in progress
  7. Satisfy personal curiosity (p 8-12).
