Writing Guide

Scientific Writing Guide for Non-PhDStudents

This guide is meant to be a general introduction to scientific writing for non-PhD students. It is meant to be starting point for getting to know the structure and to provide practical advice on the most important aspects (in my opinion).

Sections

This is a general guide to the typical sections of a scientific paper and their purposes. Not all papers will have all of these sections, and some papers may have additional sections. The specific structure of a paper can vary depending on the field, the journal, and the nature of the research. However, this guide provides a common framework for understanding the typical components of a scientific paper.

Abstract

  • Purpose: To provide a standalone, high-level summary of the entire paper. To help readers quickly decide if the full paper is relevant to their research or interests. This is the most-read part of the paper, so it should be the most polished section.
  • What it includes: The core problem (what challenge are we addressing and why is it relevant?), the approach/methods used (how are we addressing the problem?), the most important findings (what did we discover or how did we evaluate our approach?), and the main conclusion (what are the implications on the real world).
  • Tips: Write the abstract last, after the rest of the paper is complete. Keep it concise (typically 150-250 words). In most cases the abstract is a combination of a shortened introduction and a shortened conclusion.

Introduction

  • Purpose: To establish the context and explain why the research was conducted. To hook the reader and clearly define the scope and importance of the study. This section usually takes the most amount of effort to re-phrase, because every sentence counts and every word should be chosen well.
  • What it includes: Background information on the topic, the specific problem or knowledge gap being addressed, the key idea behind the approach or hypothesis being tested, and a brief outline of the paper's contributions (ideally an itemized list).
  • Notes: It is fine to overlap with the abstract. A good introduction is written so that the first sentence of each paragraph mirrors the abstract.
  • Tips on Structure: A good introduction should start from very abstract and general ideas and become more specific as it progresses The first paragraph can be written by a very wide audience. Then it becomes more concrete and might be written for a more targetted audience. Then in the end, it goes back to a general audience and broadens up to the implications of the research on the more general field.

Related Work (or Literature Review)

  • Purpose: To situate the new research within the existing body of knowledge and to prove the authors understand the field and to explicitly show how their new work is different, better, or builds upon what has already been done.
  • What it includes: A summary of previous studies relevant to the topic, highlighting their strengths and limitations. A comparison of how our work is different from theirs or how our work is based on theirs.

Approach (or Methods / Methodology)

  • Purpose: To explain how the research was conducted. To provide enough precise detail so that another qualified researcher could replicate the study and verify the findings.
  • What it includes: Detailed descriptions of the experimental design, materials, equipment, algorithms, datasets, or theoretical frameworks used.

Results

  • Purpose: To objectively present the data and findings. To state what was found without bias or subjective interpretation.
  • What it includes: The raw facts, statistics, graphs, tables, and charts resulting from the approach.

Discussion

  • Purpose: To interpret the results and explain their significance (the "so what?"). To give meaning to the data and demonstrate the broader implications of the findings.
  • What it includes: An analysis of whether the results answered the research question, how they compare to the "Related Work," and an honest acknowledgment of the study's limitations.

Conclusions & Future Work

  • Purpose: To provide a final, memorable takeaway. To wrap up the narrative and point to the next steps for the scientific community.
  • What it includes: A brief restatement of the primary finding, the overall impact of the work on the field, and suggestions for future research directions.
  • Notes: The conclusions section is NOT supposed to be a summary. The abstract is the summary. A conclusions section should synthesize the findings rather than repeat them and contextualize them.

Style

This is a general guide to the style and tone of a scientific paper.
  • Clarity: Use clear and concise language. Avoid jargon and complex sentences.
  • Hypothesis vs. Fact vs. Opinion: Clearly distinguish between hypotheses (predictions that we plan to test in the paper), facts (observations shown by other cited work or in the data), and options (subjective recommendations or interpretations that we make) throughout the paper.
  • Objectivity: Present information and arguments fairly, without bias.
  • Precision: Be specific in your descriptions and avoid vague statements. The more concrete you can be with your words and phrases (while still being correct) the better!
  • Consistency: Use consistent terminology, structure, and punctuation throughout the paper.
