Choose a developmental theory topic on which you want to write. Conduct preliminary research of developmental theories. Look up statistical studies that present findings contrary to the theory. Consider two or more theories against each other.
Develop a thesis statement. Tell the reader what point you will prove in your paper. Avoid telegraphing lead-ins such as "in this paper I will show." Trim your thesis statement down to approximately one sentence.
Introduce the theories that you will use in your paper. Assume that the reader has at most a passing familiarity with the theory or thinker.
Support your thesis statement by analyzing textual and statistical evidence from the works of the thinker, major commentators or peer-reviewed studies.
Conclude your paper by restating your thesis and summarizing your supporting arguments and evidence. Provide the reader with a sense of what implications your thesis has on the understanding and use of the developmental theory you examined.
Provide a list of citations. Follow the guidelines and style formats provided by the American Psychological Association. Review your paper to make sure you properly cited all references, quotes and statistics to avoid plagiarism.
