As far as the number of slides you should include, there is no magic number since the content you’ll have and how you talk will vary. But if you have more than 15 slides, then there better be a big reason. Don’t take us through every twist and turn of your beautifully crafted paper. What is the main story you are trying to tell with this paper? Seven-eight minutes works better for communicating an example of your theory than a lecture of the theory itself. Assume everyone has actually read everything I assigned and go from there. Use proper APA in-text citations and include reference slide at the end. The final paper that this presentation is based off can be found in additional materials.
