Method

By Xiaochi Liu in Scientific Writing

Why is a detailed description of your research method necessary?

  • to explain HOW you did your study

  • Also to give information about WHAT, WHEN, WHO, WHY

  • to enable the study to be replicated

  • to provide credibility for the results

Links with other sections (connecting the content)

  • with Introduction section (How do the subheadings in Method relate to the end of Introduction?)

  • with Results section (How do the subheadings in Method relate to the subheadings in Result?)

Types of Methods sections

  • Condensed: assumes background knowledge

  • Extended: provides full descriptions

Methods: Style & Format

Divide into subsections with subheadings

Use combination of passive and active sentences

Avoid monotony use transition phrases

Order of presenting experimental procedures

  • Chronological order

  • Most to least important

Include tables/figures only if they reduce a large amount of text

Passive Voice

Advice often given to avoid passive

  • be more direct & less wordy

  • Avoid very long subjects and a passive verb at the end of the sentence

    Wheat and barley, collected from the Virginia field site, as well as sorghum and millet, collected at Loxton were used.

  • Place subject and verb within the first 9 words of the sentence

  • Place any list of items at the end of the sentence

    Four cereals were used: wheat and barley, collected from the Virginia field site; and sorghum and millet, collected at Loxton.

Use passive

  • when the identity of the agent (experimenter) is less important than the action (experiment)

    We drew blood samples.

    Blood samples were drawn.

  • for variety (when the same agent is carrying out all the actions)

  • for modesty

  • by convention (e.g., first person pronouns I, my, me are rare in scientific papers)

  • to improve cohesion and coherence: information flow (Old -> New information)

Use both Passive and Active Sentences
