To Whom It May Concern: Some advice for students seeking references

Reference writing takes time and effort, do your best to help your referee do the best they can for you

Reference writing takes time and effort, do your best to help your referee do the best they can for you

A number of recent events have prompted me to reflect again on the subject of reference writing.

Offering a letter of recommendation, or completing one of the myriad different online forms, is not a trivial task, either in terms of the labour involved or the potential significance of the resultant document. In this post I want to make some suggestions for any students seeking a reference from an academic, regardless of their discipline, which I hope will make the process more effective (and less fraught) for all parties.

1. Ask. Firstly, do ask a potential referee before you offer their name to the organisation seeking the reference. On one level this is common courtesy. However it also does two things to the benefit of the applicant: it forewarns the academic that they need to budget some time for writing a reference and gathering the relevant information (see 3, below); it also gives them the opportunity to suggest a more appropriate referee for the specific job. Unless there are exceptional circumstances, the first person you should ask for a reference is your personal tutor. For finalists or graduates requiring a second academic commendation the next person to ask is usually your project supervisor. Continue reading

Letting students know what we expect in essays

At a recent student-staff committee meeting, a first year student rep noted that it was difficult to know what sort of things markers would be looking for in an essay (especially since many people had no cause to write essays at all during their A level science courses).

I was able to point him to the generic guidance we offer in the Undergraduate Handbook, issues to all new students. However, I also wondered whether we ought really to give more information (particularly when we likely give *markers* of the work quite a thorough checklist). So this year I’ve decided to send an email overtly pointing out the kind of things that gain or lose marks (see below). Critics might argue either that (a) this is undue spoon-feeding or (b) that it will make it harder for us to find criteria on which to comment. I would counter this by saying that ironing out of some of these issue should make it clearer for us to actually get into the *content* of the essay we are assessing and not end up so focused on the *production and process* that we barely get into discussion of the substance of the essay proper.

Anyhow, we’ll see how it goes.

Criteria markers may be judging:

  • Has the essay got the correct title (not some vague approximation to it)?
  • Does the essay have a proper introduction and conclusion?
  • Are references cited in the text (using the Harvard system)? Is there a well-organised reference list at the end?
  • Does the essay answer the question posed in the title?
  • Is there a logical flow to what has been written (or is a random collection of points, albeit valid points)?
  • Is the sentence construction good? Are there issues with paragraphing? Is the story “well told”?
  • Has selective or partial coverage of the topic, inevitable in short essays, been justified in any way?
  • Have other instructions been followed e.g. is the essay double-spaced? page numbers? word limit?
  • Are there diagrams? Do they have: Figure number? Title? Legend (if applicable)? Are they referred to in the text? Are they neat and fit for purpose? If “imported” from a source are they cited?
  • Is the title and/or legend “widowed” (on a different page) from the image?
  • Is there inappropriate use of quotes?
  • Is the essay clearly too long (or too short)?

Finding research articles that are worth finding

An enormous amount of scientific literature is generated each month

The world is awash with scientific papers. Even if we restricted a survey to research within biological sciences, I guestimate that there are more papers published each month than your average academic could be expected to read in a lifetime. In these rich fields of information, how are students unfamiliar with the genre  to develop the ability to discern the wheat from the chaff (let alone the weeds)?

At the University of Leicester, we have a task for undergraduates, conducted towards the end of their second year, in which they produce a poster describing a particular research method (selected from a short list relevant to their chosen discipline). As part of the exercise, the students need to choose a primary research article which illustrates one application of that method.

It is fair to say that many of the students initially struggle to select an appropriate paper*. There are several reoccurring  problems:

  • Failure to distinguish between a research article and a review
  • Failure to recognise that all journals are not equal in terms of their academic quality and rigour of the work they publish
  • Selection of papers that do not really utilise the technique that should be the focus of their poster.

In truth, the ability to select the right kind of paper is one of the important learning outcomes from this exercise; these students will commence their final year dissertations immediately after they return from summer vacation and need to avoid wasting hours reading papers that are not worthy of their attention. However, since I frequently find myself making the same points in email correspondence with individual students, I felt it was worth using this forum to share some of my overarching reflections on the fine art of finding appropriate research articles.

Research Article or Review?

Most searches these days are conducted online

When we’ve been involved in academia for many years, knowing whether a paper is a primary research paper or a review comes as second nature. This is not necessarily true for inexperienced students. In their defence, the variation of the naming of research articles in different journals does not help. Cell and EMBO Journal call them “Articles”. Nature also has “Articles” but the majority of original research is labelled as “Letters” and in Science primary literature is mostly “Reports” .

Although it ought to be possible to spot a research article by the sub-sections it contains (i.e. Abstract, Introduction, Materials and Methods, etc…) these are not necessarily given the same names in all journals, and the order in which they included can be different. Of course, if the journal has the word “Review”, “Trends in…” or “Current opinions in…” then it is likely to include, almost exclusively, articles summarising the research of other scientists rather than containing original reports of new experiments . But in other journals a review might actually be called “Perspectives”, “Commentary” or “News and Views” to name but three.

Review articles as a mean to an end

For the specific activity we set our students (finding a primary research paper that demonstrates the use of a particular technique), reviews are not going to be a suitable destination. This does not mean, however, that review articles are of no merit in the search for good quality experimental data. In some senses, the authors of a review article have done crucial legwork for you. Already experts in the field, they have read broadly about the topic and will then have selected what they consider to be the most significant recent experiments for their reflections. Looking at the reference list in a review can therefore be an efficient way to shine a light on the best primary literature.

Is it a good paper?

If you are not familiar with a research technique or particular discipline, how can you know whether a paper is a “good” paper? There are three useful clues. The first is the one we have just described, namely do authors of reviews rate the work as worthy of their attention?

Secondly, where has it been published? Like it or not, there is a hierarchy of journals; some titles are in the Premier League, some are in the Championship, and some are non-league. Experienced heads know that research published in Nature, Science, Cell, Proceedings of the National Academy of Science and EMBO Journal is considered (usually with some justification) to be more worthy than papers coming out in the Journal of Knitting and Spectroscopy, but recognising this is, once again, an aspect of the maturing of undergraduates into fully-fledged scientists.

Thirdly, how many times has the work been cited by other researchers? If work has been in circulation for fifteen years but has only been quoted twice during that period, and both times by the author of the original paper, then it is fair to conclude that it did not contain ground-breaking discoveries. One of the useful features of Web of Knowledge is the citation count. If you don’t have access to Web of Knowledge, Google Scholar has a similar (though slightly less rigorous) feature.

Finally, if you want to refine a search so that it is restricted to only those “Premier league” journals name above,  then why not go to a journal’s own search engine rather than, or in addition to, a more generic search tool? (e.g. for Nature, for Science).

* Note, if you are wondering how this squares with my recent description of a  source evaluation exercise for first years, I need to point out that this is NOT the same cohort.

Making the best of “Bad Science” (Review)

Harper Perennial edition (2009)

Harper Perennial edition (2009)

If you have not yet read Ben Goldacre’s book Bad Science, then I thoroughly recommend that you do. As readers of his regular Guardian column or his website will already know, Goldacre has embarked on a campaign to root out example of pseudoscience and shoddy science whereever they may be found.

All the usual villians are present – homeopaths, nutritionists, slack journalists, pharmaceutical companies and AIDS dissenters. Some are mentioned by name, but given their alleged predilection for litigation, and since I do not have the time, the money or the inclination to do battle with them in the courts, I shall not repeat their identities here!

It would be wrong, however, to give the impression that Goldacre is merely on a crusade against high profile exponents of “bad science”. True, the author does sometimes betray a little too much glee as he places a bomb under the throne of a media “health expert” (in a way that I found disturbingly reminiscent of the Physiology lecturer, when I was a first year undergraduate, recalling his boyhood experiments on frogs). Nevertheless, Goldacre is keen to emphasise that his purpose is to “teach good science by examining the bad” (p165 in my copy), adding that “the aim of this book is that you should be future-proofed against new variants of bullshit” (p87).
