Searching the Literature
  • A literature search has three main purposes
  • to summarize prior research in a specific area,
  • to evaluate prior research,
  • to define/refine your research project.
  • Conducting a literature review helps you avoid
    naiveté, repetition or unnecessary work. Before
    you begin your own project, you must know
    something about what has been done in that area
    already.

Writing a Lit Review
  • Written literature reviews typically serve one of
    two purposes
  • Synthesize (and evaluate) research in an area for
    interested professionals (informative)
  • Demonstrate your credibility and the need for
    your proposed project to clients/funders
    (persuasive)
  • Think of a lit review as an orchestrated
    conversation with you as the conductor.

FOUR STEPS TO THE LITERATURE REVIEW
  • 1. Research Primary Sources
  • Focus on timeliness and comprehensiveness
  • 2. Analyze And Select Studies
  • Evaluate articles and locate major findings
  • 3. Synthesize And Integrate Findings
  • Group and cluster prior work to present trends
    and patterns across studies
  • 4. Discuss General Conclusions
  • Outline future implications and influences on
    field
  • Clear space for your own work

Tips for Literature Reviews
  • Brainstorm topics related to your project look
    at the edges of your project to determine what
    you need to know
  • Use academic/government databases, professional
    society web sites, and selective internet
    searches to examine the literature before you
    start to write. Focus on peer-reviewed, archival
    sources.
  • Assess work to determine research questions,
    methods, materials, and findings to get a feel
    for what you can say about the literature
  • Learn to skim (abstracts, introductions,
    conclusions)
  • Use other peoples bibliographies to lead to
    important prior work.

Tips for Literature Reviews
  • Dont get bogged down dont spend time with
    irrelevant articles and dont think that you can
    review every possible relevant source
  • Record all references with annotations begin a
    bibliography
  • Practice good note taking, abstracting skills
  • Thematize the literature into coherent
    subheadings based on your goals
  • Develop a working thesis what can you say about
    the state of the art?
  • Find an order for presenting the material based
    on your goals
  • Set a stopping point (then return to the review
    later)

7
Questions for Evaluating Sources
  • What problem/issue does the work address?
  • What methods does the author use?
  • What are the major findings?
  • What are the major gaps or next steps?
  • How does this work relate to your project? What
    can you use? What elements are important to build
    on?

Sticky-Note Lit Review
  • Brainstorm One topic per sticky note
  • Details related to your project
  • Information needed for the project
  • Consider Materials, Designs, Background,
    Mathematics, Mechanics, Prior research, Impact on
    society issues
  • Organize sticky notes into general themes
  • Organize themes into an outline
  • Plan your research tasks
