o Broad to narrow: Focus the Introduction around the hypothesis, specific questions, or aim of your
study. The Introduction can be represented as a cone: start with known information and narrow
down to your specific study.
Figure 1: Annesley TM. “It was a cold and rainy night.” Set the scene with a good introduction.” Clinical Chemistry 56 5 (May 2010): 708-713.
o What is known: First, provide context and background information about what is known on your
topic.
o What is NOT known: Then move from what is known to what is NOT known. Pinpoint the gaps
and limitations of previous studies. Include several citations in the Introduction, not just one or two.
What were the limitations of those studies that make the results uncertain?
o Hypothesis: Your Introduction should end with your hypothesis or specific question and explain
your approach to the research problem.
Methods
o Past tense: Write your Methods section in past tense (e.g. “We measured…”), as you’ve already
completed the research.
o Voice: The Methods section is the one place in your paper where you may opt to use passive voice.
(Remember: passive voice emphasizes the action and object: “The sample was placed under the
microscope.” Active voice emphasizes the subject: “We placed the sample under the microscope.”
o Recipe for replication: The Methods section should give a clear overview of how the research study
was conducted: it is the recipe for the study. It gives sufficient information so that someone else
could replicate the study.
o Narrative structure: This section should be written as a narrative, not as directives. For example,
instead of writing “Place the sample under the microscope,” say either “The sample was placed under
the microscope,” or “We placed the sample under the microscope.”
o Subsections: The Methods section should be written in paragraph form. You can break your
methods into smaller sections with subheadings (discuss related methods together) to help with
organization.
o Details: The Methods section should contain information about the following:
▪ Materials used to conduct the study (e.g. drugs, buffers, chemicals, gasses, reagents,
telescopes, microscopes, weighing scales, questionnaires, etc.)
▪ Experimental conditions (e.g. climate, pH, doses, replications, study subjects)
▪ Study subjects (if used) (e.g. type and sex of organism, weight, height, diet, etc.)
o Rationale: As you describe your actions during the experiment, explain your rationale for the any
protocol you developed. If you capped a test tube immediately after adding a solute to a solvent, why
did you do that? (That prompts two questions: why did you cap it, and why did you cap it
immediately?) Provide rationale as a way to explain your thinking to potential critics.
