Sometimes it helps to create an outline before you attempt to write as a template to your completed project. Resumes often work in that manner, and that method could very well help you with your writing needs.
One thing to consider is to look from the perspective of a finished project like what the teacher or editor would expect out of your work. Include anything defined by the assignment, and any expectations you have for yourself. You may be in the position to plan basic context (or answers to basic questions) and play around with how you intend on introducing the concepts.
The beginning of academic papers should have some eye catching, attention grabbing first line. It should then summarize the paper asking the research question(s) your paper intends to answer. In addition, this is a great place to include the relevance of the topic, the scope of your research, and any introductory information the reader should know before reading your paper.
For articles such as news articles and blogs, the beginning should answer all the questions of who, what, when, where, why, etc., in the first paragraph. In addition, the most important information should go first. Try to make it eye catching, awesome, fun read to engage interest, but that’s more important to do in the headline than your first paragraph.
Information has to be organized in a way the reader can quickly, easily comprehend. Headings are a great way to organize information so that readers can find specifically what they are looking for, and it helps focus their mind on what to expect. In addition, paragraphs should be thought of as “Main Topic” followed by “Supporting Details.” You are free to decide where the main topic goes in the paragraph.
Academic papers generally require a summary answering whatever research question was found in your introduction. Articles and blogs usually end with places to find more information.
