In the GCU library, locate four empirical studies you have not used before on a topic you are interested in researching (Use the Empirical Research Checklist to determine if a study is empirical). List the theoretical foundation and Permalink for each study, and add the studies to your RefWorks list. Then determine a theoretical foundation for a study that you might like to research for your dissertation. Why did you select this foundation? Finally, comment on other learners’ theoretical foundations and if/how they can be improved.
