How many sources do you need in a literature review?

February 19, 2014

Students often ask me how many sources they need in their literature review. The short answer is, “It depends.” It depends on your topic, the nature of your research project, your level of scholarship, and a number of other factors.

An article from Canberra University (http://www.canberra.edu.au/studyskills/writing/literature) suggests:

  • Undergraduate review: 5-20 titles depending on level
  • Honours dissertation: 20+ titles
  • Master’s thesis: 40+ titles
  • Doctoral thesis: 50+ titles

Another strategy I learned somewhere along the way that I now share with my students is this:

If your literature review is one section of a larger research paper, thesis or dissertation

Minimum number of sources = number of pages in the body of your entire paper (exclusive of title page, abstract, appendices and references)

Example: A paper that has 10 pages of content (the body of the paper) needs at least 10 sources in its literature review. 

A thesis of 100 pages (in the body) includes at least 100 sources.

If your literature review is a stand-alone document

Minimum number of sources =  3 times the number of pages in the body of your paper (exclusive of title page, abstract, appendices and references)

Example: A stand-alone literature review that has 10 pages of content (the body of the paper) should examine at least 30 sources.

These are not hard and fast rules by any means. Also, it is worth mentioning that as students and scholars who care about the quality of our work, we want to aim to raise the bar, not simply meet a minimum suggested standard. What these guidelines are suggesting is that you don’t aim for any less. If you do, your search for relevant literature in your field may be incomplete and you need to keep digging. Of course, your sources have to be relevant to your topic, too.

Not every scholar or academic supervisor would agree with the guidelines I offer here, criticizing them as being too reductionist or simplistic. My point isn’t to offer a black and white rule or to open a theoretical debate for which there can be no clear solution, but rather to offer a straight forward and practical answer to a question that academics often respond to in an ambiguous way, leaving students frustrated, exasperated, and anxious about how to go conduct their literature review. 

When in doubt, talk with your own instructor or supervisor, asking them what their expectations are. (Don’t be surprised though, if you get an answer that is vague, like, “It depends…”)

Remember: Aim for quality over quality… and to do a quality literature review, you need to have a substantive quantity of sources.

Why APA formatting matters

January 15, 2014

Imagine you are buying a new home. You tour around a number of properties. You see one that is messy, distasteful and uninviting. The sales agent says, “Oh, don’t worry, the foundation is strong!” The trained eye may be able to see beyond the bad presentation, but it takes a lot of mental energy to get past it.

Now imagine you are taken into a home that is clean, neat and perfectly staged. You immediately feel welcome. You are instantly engaged psychologically and emotionally. You want to see more.

APA formatting is to research papers what presenting a clean, neat and well presented home is to selling a property.

Your prof may be able to look past a messy presentation, but it takes more mental energy. You want to be able to say, “Oh, but the foundation of the work is just fine!”  and you want that be enough.

Well, it’s not enough. It sends a message that you don’t care about presentation. You send a message that you don’t give a flying leap that your work is less appealing to read. You may be brilliant, but if the essence of what you show to others messy and disorganized,  it’s less inviting to enter your world and spend time there. Sometimes, students insist that APA formatting inhibits their creativity or individuality. My reply to that is, fine, go be as bizarre and unique as you like in your own writing space — your blog, your journal or whatever.

There’s an element of persuasion involved in writing a research paper. I won’t say sales, because that will undoubtedly offend some of you. But let’s face it. You are trying to “pitch” your ideas. Follow standard practices for presentation and your work is likely to be accepted a whole lot faster than if you insist on doing it your own way. When you are writing a research paper you are trying to persuade someone to read it, like it and possibly judge its value (e.g. accept it for publication or award a grade for it). 

Sometimes I find that drawing comparisons between reality TV and academia helps students make sense the expectations of life in higher education. Over the past few months, I’ve been watching Income Property. I don’t own any income properties and I probably never will, but I find the show fascinating. I see patterns in how projects are completed so they consistently meet the objectives.

Host Scott McGillivray helps home owners turn unfinished or unacceptable suites into beautiful rental properties. He and his crew completely renovate the space. They focus on doing excellent quality construction, electrical and plumbing work that is up to code. The work is inspected and they get feedback from city officials and inspectors before they start working on the finishes.

To me, that’s the the content of research. It needs to be solid, high quality and done well. Getting feedback along the way is important, too.

Once they get the necessary approvals that the job has been done right, they move on to the finishes. They pay attention to the details and ensure the look of the place is consistent with sound design principles that are timeless and impressive. After watching a few episodes of Income Property I noticed that they use very similar approaches for each project.

http://www.sxc.hu/photo/670220That’s the presentation of the work. The design principles are outlined by APA, MLA or whatever style guide you use. The format is timeless and paying attention to the details makes it impressive. They follow presentation design principles systematically. Each project is unique, yet they follow standards in a consistent way. It’s almost like there’s a template and yet, every project is individual.

McGillivray consistently points out that doing the construction work properly is non-negotiable. Just like doing high quality research is non-negotiable.

But what gets people to say, “Wow, this is impressive!” are the finishes. Following accepted practices for presentation (which might be interior design for a house, or formatting for a paper) and paying attention to the details are what makes you stand out and be impressive.

For an exemplary end product you need both: quality construction and beautiful finishes. If you have only done only one or the other, you are being sloppy. To do the job right, you need solid construction and a beautiful presentation.

50 Adverbs to avoid in academic writing

July 2, 2013

Most academic writing is strengthened by eliminating adverbs. To emphasize a point, provide more evidence to support it. Avoid unnecessary words and in particular, adverbs. Instead, choose more precise verbs.

An adverb modifies or describes:

  • A verb (e.g. He runs quickly.)
  • An adjective (e.g. His writing is extraordinarily descriptive.)
  • Another adverb (e.g. He runs extraordinarily quickly.)

Often, but not always, adverbs in English end in –ly. Here are 50 adverbs that I have seen in academic papers that you can eliminate and your writing will be better for it:

  1. Adroitly
  2. Amazingly
  3. Awesomely
  4. Badly
  5. Basically
  6. Carefully
  7. Clearly
  8. Completely
  9. Convincingly
  10. Deftly
  11. Desperately
  12. Dexterously
  13. Effortlessly
  14. Extremely
  15. Faithfully
  16. Fundamentally
  17. Generally
  18. Goodly
  19. Honestly
  20. Inherently
  21. Instantly
  22. Interestingly
  23. Narrowly
  24. Naturally
  25. Nearly
  26. Necessarily
  27. Obviously
  28. Precisely
  29. Previously
  30. Preposterously
  31. Quite
  32. Really
  33. Relentlessly
  34. Simply
  35. Spectacularly
  36. Successfully
  37. Suddenly
  38. Surely
  39. Truthfully
  40. Ubiquitously
  41. Unequivocally
  42. Ungodly
  43. Unnecessarily
  44. Unquestionably
  45. Utterly
  46. Unwittingly
  47. Usually
  48. Very
  49. Widely
  50. Zealously

Often, when writers make a conscious choice to eliminate adverbs and instead find stronger and more precise verbs, the result is writing that is clearer and more powerful.

Why “as cited in” should be avoided in academic writing

May 21, 2013

For my graduate students… and other readers:

When you are referencing others’ work in our course, whether it is on the discussion board, in your presentation or in your final paper, I urge you to find the primary sources for your citations.

I will be upfront about this and say that I am not at all a fan of citing a work that someone else has cited. Please find the original reference yourself and cite that instead.

The reason for this is three-fold:

  1. You want to be sure that the “original” author actually exists. As heinous as it may seem, people have been known to fabricate references.
  2. More common is that a researcher will mis-quote an author or take someone’s work out of context. By going back to the original source, you have the opportunity to verify for yourself what the original author was trying to say.
  3. “As cited in…” can be an indicator of either a lazy or disinterested scholar who does not care enough to find and cite original authors. I do not think this is the case with anyone in our course, but it is not uncommon for other scholars to dismiss the credibility of a researcher who does not take the time to find primary sources.

Earlier this year, I conducted an informal in-class experiment with a Master’s level class at the U of C. I challenged them to find the original version of Maslow’s “Hierarchy of Needs”. To their surprise, they found that the pyramid that has become an iconic representation of Maslow’s hierarchy is nowhere to be found in his original work. (You can read about it here: Maslow’s hierarchy of needs: Is the pyramid a hoax?  http://wp.me/pNAh3-1rU)

I tell my students, “My point to you is this: Please cite only primary sources in our course. Avoid using ‘as cited in…’ or similar strategies. If you can’t find an original source, don’t cite it.”

The only exception to this would be original works of extreme rarity which are almost impossible to source without physically visiting historical archives.
