This study examines the reliability of student evaluations of summer undergraduate research experiences using the SURE (Survey of Undergraduate Research Experiences) and a follow-up survey conducted 9 months later. The study investigates whether undergraduate research enhances the educational experience of science undergraduates, attracts and retains talented students to science careers, and serves as a pathway for minority students into science careers. Undergraduates participated in an online survey assessing the benefits of research experiences and their career plans. Most students began or continued planning for postgraduate education in the sciences. A small group who discontinued their plans reported significantly lower gains than continuing students. Women and men reported similar levels of benefits and career plans. Undergraduate researchers from underrepresented groups reported higher learning gains than comparison students. The results replicated previously reported data from this survey. The follow-up survey indicated that students reported gains in independence, intrinsic motivation to learn, and active participation in courses taken after the summer research experience. The study found that students who continued their education in science reported higher learning gains than those who discontinued their plans. The results also showed that students who worked at an institution other than their regularly enrolled institution reported higher gains in several areas. The study highlights the importance of undergraduate research experiences in enhancing student learning and career decisions. The findings suggest that undergraduate research experiences have a lasting impact on students' academic and career paths. The study also emphasizes the importance of mentorship in undergraduate research experiences. The results indicate that students who had positive research experiences were more likely to continue in science. The study concludes that undergraduate research experiences are valuable for students and contribute to their academic and career success. The study also highlights the importance of addressing the needs of underrepresented groups in science education. The findings suggest that undergraduate research experiences can help retain minority students in science careers. The study also notes that the influence of undergraduate research experiences on student learning and behavior persists over time. The study concludes that undergraduate research experiences are an important component of science education and contribute to student success. The study also emphasizes the importance of continued research and evaluation of undergraduate research experiences to improve science education.This study examines the reliability of student evaluations of summer undergraduate research experiences using the SURE (Survey of Undergraduate Research Experiences) and a follow-up survey conducted 9 months later.
