The purpose of an evaluation research paper is to determine the worth or significance of the subject you are evaluating. You should begin by introducing the subject that you are evaluating. You should then state your evaluation or opinion of the subject. This is similar to the thesis in an essay because you will be supporting this point throughout the paper.
The body of the paper should contain supporting evidence to show why your evaluation is correct. Try to use strong resources to support your evaluation.
Next, you should acknowledge the opposing viewpoints to your evaluation. You will use evidence to prove that these viewpoints are incorrect.
Finally, end the paper by restating you evaluation and summarizing why your view is correct.
