Student work

Students across a range of specializations work with Dr. Barbieri on a variety of research projects. Student bios and project descriptions are listed below. Dr. Barbieri is currently accepting PhD advisees in either Learning Sciences or Educational Statistics and Research Methods. Please contact Dr. Barbieri directly at barbieri@udel.edu if you have additional questions about her research program. If you have interest in being Dr. Barbieri’s advisee, please note this in your application letter and explain how your interests align.  Applications to both programs are due December 15 for enrollment in the 2021-2022 academic year. UDSOE doctoral students receive funding for 4+ years.

If you are a current undergraduate student in the College of Education and Human Development and are interested in a part-time research apprenticeship (8-10 hrs/week) with Dr. Barbieri, please submit an application here to be considered. This is a paid apprenticeship through the CEHD’s Undergraduate Research Apprenticeship Program (URAP).

Dr. Barbieri also works with University of Delaware Research Apprenticeship Work-study (UDRAW) undergraduate students. This is a University-wide program (not restricted to CEHD). To participate in research as part of work study, please refer to the UDRAW website.

Dr. Barbieri also mentors undergraduate students from other universities who participate in UD’s summer Undergraduate Research Scholars (URS) program. To apply, contact Dr. Barbieri about your potential interest and see the URS website for application information.

Doctoral student collaborators

Kamal Chawla

Kamal Chawla is a PhD student in Educational Statistics and Research Methods (ESRM). He is from New Delhi, India. He graduated from the Indian Institute of Technology (IIT), Roorkee, India, with a Master’s degree in Industrial Mathematics & Informatics. Before that, he finished his Bachelor of Science (Honors degree in Mathematics) from the University of Delhi, India. He has been interested in integrating applied mathematics with research problems in various disciplines. Throughout his studies, his inclination grew towards statistics and numerical analysis tremendously. The use of statistical sampling and hypothesis approach and numerical methods such as ‘Lagrange Interpolation’ and ‘Newton forward and backward interpolation’ has helped him to develop his understanding and analyze different real-life situations. He later joined The Princeton Review, Noida,India as a Quantitative Aptitude Trainer. This position acted as a catalyst in his decision to opt for education as a career. He has gained a much-needed vantage point regarding the profession of teaching and its significance after closely working with students and peers alike that helped him to build valuable relationships with them. His research interests are Mathematics Education and Evaluation of Mathematical Competencies.

Sarah Clerjuste

Sarah Clerjuste was born in Haiti and raised in Pompano Beach, Florida. She received her B.A. in Mathematics at the University of Florida where she also tutored mathematics and participated in various research projects.

Sarah is a PhD student in the Education Statistics and Research Methods (ESRM) program within the School of Education. Her research interests include mathematical cognition, mathematical comprehension, and program evaluation.

Aneysha (AJ) de Coteau

AJ is a PhD student in the Sociocultural and Community-Based Approaches to Research and Education (SCA) specialization in the School of Education. She is from the twin island nation of Trinidad and Tobago. She received her Bachelor’s degree with honors in Musical Arts from the University of the West Indies, St. Augustine campus. She went on to earn her Master of Music in Teaching in 2018 from the University of Delaware, where her thesis explored the influence of past music making experiences on LGBTQ+ students’ identity construction. Her current research interests include race and diversity in education, queer theory in education, equity in education, and teacher preparation for diversity.

AJ’s work with Dr. Barbieri focuses on examining the effects of various instructional materials on Preservice Teachers’ metacognitive monitoring processes when explaining how to solve fraction magnitude comparison tasks. AJ’s work was accepted for presentation at the 2020 American Educational Research Association (AERA) meeting. AJ is also examining the relationship between mathematics and music education.

Brianna Devlin

Brianna Devlin is a PhD student in the Learning Sciences specialization in the School of Education. Her research interests include the development of mathematical cognition in children and factors that affect young children’s acquisition of early numerical concepts and skills, especially in children at-risk for later mathematics learning difficulties.

Bri’s work with Dr. Barbieri focuses on examining the various forms of children’s magnitude reasoning evoked by number line representations of fractions and how this relates to their learning of fraction concepts. Bri presented this work at the Cognitive Development Society 2019 Biennial meeting in Louisville, KY.

Kelly-Ann Gesuelli

Kelly-Ann Gesuelli is a Ph.D. candidate in School Psychology at the University of Delaware. She has long been interested in investigating the aspects of learning disabilities, which she initially studied from a molecular standpoint while completing her M.S. in Physiology with a specialization in neuroscience at SUNY Upstate Medical University.  Her transition from science to the fields of psychology and education was fueled by her desire to help advocate for special education students, as well as her personal experiences mentoring special needs students and as an intern at the University Medical Center of Princeton at Plainsboro’s Eating Disorder Care. Her current research interests include the development of math RtI programs for students with disabilities and the use of student error reflection in such programs.

Kelly-Ann’s work with Dr. Barbieri focuses on preservice teachers’ ability to successfully detect and address students’ mathematical errors and how that varies by student strategy use. Kelly presented this work at the Cognitive Development Society 2019 Biennial meeting in Louisville, KY.

Gerilyn Slicker

Gerilyn is currently a Ph.D Student in the Department of Human Development and Family Sciences (HDFS) at the University of Delaware and a Research Assistant at the Delaware Institute for Excellence in Early Childhood. Gerilyn’s research interests include school readiness, the transition to kindergarten, and young children’s access to culturally diverse, high-quality early care and education, with an emphasis on the evaluation and development of state- and federal-level early childhood policies. Gerilyn comes to the University of Delaware with a Bachelor of Arts degree from the University of California, San Diego in both Sociology and History, a Master of Arts degree in Sociology from the George Washington University, and a Master of Education degree in Early Childhood from The University of Nevada, Las Vegas. Previously, Gerilyn taught pre-kindergarten in the Head Start and charter school setting and served as a Head Start center director, instructional coach, and education leader. Gerilyn hopes to attain a career in academia, where she will continue to conduct research and deliver instruction at the university level.

Geri is working with Dr. Barbieri using a secondary dataset (ECLS-K) and mixture modeling to examine the role that parent expectations about kindergarten readiness and parent-child home activities have on children’s early mathematics and reading skills. Gerilyn’s work was accepted for presentation at the 2020 American Educational Research Association (AERA) Annual Meeting and has a manuscript on this project under review at a peer-reviewed journal.
