Background: Previous research has indicated positive changes in student perceptions of primary literature using the CREATE primary literature approach (a collection of guide tools for reading primary literature). Objective: The objective of this research was to examine how a modification of the CREATE approach relates to student perceptions of primary literature and STEM career interest in psychological sciences courses. Method: The CREATE approach was modified for use as a one-time project and assessed in (1) two course levels (introductory-level and senior level) and (2) two course deliveries (face-to-face and online). Participants filled out a survey with six factor perceptions of primary literature and STEM careers before and after project administration. Results: After project completion, there was a significant increase in perceptions of primary literature (five of the six factors), but not STEM career interest. Conclusion: There were significant increases over time (pre- to post-survey) in five of the six factors of perceptions of primary literature, but there was no change in the "thinking like a scientist" factor or STEM career interest. Teaching Implications: This one-time project can concurrently be administered with textbook-based curriculum in online or face-to-face psychological sciences courses to introduce students to primary literature.
