This study examined students' perception between short research experiences (SRE) courses and full-semester course research experiences (CRE) using the Persistence in the Sciences (PITS) survey and the interview questionnaire. The study also aimed to correlate the influence of student's demographic as a predictive indicator for Project Ownership Scores (POS) and Quantitative Literacy (QL) score means. The three courses studied at the University of North Texas were Biology for Science Majors Laboratory (BIOL 1760 SRE), Microbiology with Tiny Earth (BIOL 2042 Tiny Earth SRE), and Introductory Biology Research Laboratory I (BIOL 1750 SEA-PHAGES CRE). The mean scores for the PITS categories leaned favorably towards the research component of each laboratory course assessed in this study. The interview questionnaire showed 66% of the students in the SRE courses and 90% of the students in the CRE course preferred the research component of the lab. Paired survey demographic analysis for BIOL 1760 SRE showed significance for the Science Community Values with associate/bachelor's degree. BIOL 1750 SEA-PHAGES CRE showed significance in three of the six categories when comparing means for Project Ownership Emotion, Self-Efficacy, and Science Identity with Gender. Binary logistics was used to build a regression model to predict demographics with approximately 65% …
