The best way to beat that anxiety is to have a rock-solid plan that will take you to a successful result.
When you’re taking actionable steps towards tangible goals, the research paper challenge seems possible to tackle.
Once the first sentence has introduced the broad field, the next sentence can point to the specific area within that broad field.
As you may have noticed, the papers in the examples mentioned above introduced the subfield by mentioning 1) remission of some types cancer following accidental infection by Streptococcus pyogenes, 2) organic matter in soil as a source of nutrients for plants and of energy for microorganisms, and 3) imaging techniques to visualize the 3-dimensional structure of the materials and components of batteries on nanoscale.
If, for example, your research was about finding the right proportions of two metals in an alloy and you tested ten different proportions, you do not have to list all the ten proportions: it is enough to say that the proportions varied from to .
Compared to two other sections of a typical research paper, namely Methods and Results, Introduction and Discussion are more difficult to write.
It's also not efficient to do too much research before you really know what you're looking for.
Try it our way--develop that research question first--to cut out a lot of research paper mess.
You can also think of the Introduction as the section that points out the gap in knowledge that the rest of the paper will fill, or the section in which you define and claim your territory within the broad area of research.
The other job the Introduction should do is to give some background information and set the context.
