Writing a Scientific Paper - Introduction and Methods Sections


Introduction

The introduction is the part of the scientific paper, where you explain the background information, how it relates to your topic and why your topic is important. You do this so that your readers will understand the background and are able to put your work and results into the context of the literature related to the subject.

The introduction should:

  • Be relatively short
  • Explain why the paper is interesting
  • Give any background information needed to interpret the results

The introduction should define the problem, link the work to previously published work and define any specialized terms.

The introduction will cite all the relevant literature, in the format specified in the journals style guide. The full references will be included in the reference section.


Aim

The aim should tell the reader specifically what you want to achieve. It's where you state what you'll do.

The aim should be stated clearly. If needed, the aim can be split into several parts. You can have several aims within one paper. They however should be linked together.

The aim should be included as the last paragraph of the introduction.



Materials and Methods

The methods section is where you explain what you did. You need to give enough detail for another scientist to be able to repeat your experiments from reading your paper and any references you give to methods you followed.

The methods section should be subdivided, especially in larger papers, so that the methods used for each part of the work are easily identifiable.

The methods section should include:

  • The design of the experiment
  • Exact descriptions of any organisms used in the study (full scientific names)
  • The materials used (e.g. chemicals) including the source and technical specifications
  • The exact methods used, with as much detail as is needed to repeat them, include references to previously published methods note any modifications you make
  • The methods you use for data analysis

You should use standard units and make sure that any abbreviations used are defined. Include the number of replications used in your experimental design.
