Scientific Writing Conventions


The IMRaD Structure


Most scientific papers follow IMRaD format:



  • Introduction: What is the question? Why does it matter?

  • Methods: How did you investigate? (Reproducibility is key)

  • Results: What did you find? (Data and observations, minimal interpretation)

  • Discussion: What do the results mean? How do they relate to existing research?


Scientific Writing Style



  • Precise, unambiguous language

  • Third person, passive voice (though active is increasingly accepted)

  • Present tense for established facts, past tense for specific experiments

  • Quantitative: specific numbers, not "many" or "significant" without data
