Explanation of the parts of a scientific research article, how to read scientific articles, books about the research process, how to do a literature review, forming hypotheses, research design, research instruments, finding statistics & survey results.
Articles in scientific journals are called "primary literature". They report the actual study or experiment, the results and conclusions from those results. In the sciences, they usually have been "peer reviewed" - that is deemed worthy of publication by a committee of scientists in the field.
You should approach reading an article in a science research journal with a purpose and a plan. This process is outlined in the, How to Read a Scientific Paper tutorial from Purdue University linked below.
