If you find this difficult to do,
then a useful approach is to write the report as if it would be read by someone you know who is intelligent but unknowledgeable about your subject.
A friend of yours, say. Write it as if this person were going to have to read and understand it.
Indeed, it is a good idea, if you can, to get just such a person to read your report before handing it in.
The demands and expectations placed upon you will of course, vary with your experience of report writing.
Early on in your study, as an author of experimental reports, less will be expected of you than later.
At this early stage, you will be expected mainly to show that you understand what you did in your report and its implications,
together with evidence that you have, at least a basic grasp of the demands of the report's format.
Later on, however, you will be expected to pay more attention to this research significance of what you did.
The "why you did it" part will become more important because in being responsible for the choice of topic and design, you will be expected to be able to justify this choice.
So you must be able to tell us why it is, that given the options available to you, you decided to conduct your particular study.
You will need, therefore, to develop the habit of thinking about how the ideas that you're entertaining for your experiment or study will look in the report,
paying particular attention to how they will fit into the part of introduction.
Specific dangers that you must watch out for here are, first, a lack of adequate material to put in the section;
and second, the undertaking of a project that lacks any research justification, because it is based on assumptions that are contradicted by existing findings in the area.
Thinking clearly in advance will help you to avoid making these mistakes.
OK. Today we've had a brief look at the format of an experimental report, what each section is about and some of the basic issues like reader awareness, so on and so forth.
Next time, we will discuss how to write up the introduction section.
