Guiding students to reimagine their relationship to mathematics
Clinical Professor of Mathematical Studies, Division of Applied Undergraduate Studies at NYU SPS
Nexus: What do you teach?
Donatella: This semester (Spring 2025), I am teaching Linear Algebra, Precalculus, and Mathematical Reasoning. I have also taught Calculus with Applications to Business and Economics in the Division of Applied Undergraduate Studies at NYU SPS, where I have been teaching since 2003.
Nexus: What teaching practice, activity, or technology do your students benefit from the most?
Donatella: During my synchronous online class sessions, one of the most effective tools I've implemented is structured participation through the Zoom chat feature. I review chat transcripts weekly using a clear grading rubric to track student engagement.
My tip for faculty is to set clear expectations for chat contributions and encourage thoughtful, relevant input. This approach has proven particularly valuable given that my class sessions are 2.5-hours long. Through continuous questioning, each session generates over 200 chat responses in a class of 25 students, demonstrating consistent engagement. One student from my Fall 2024 course noted:
“The fact that everyone has to participate everyday makes it easier to stay focused since the class is on Zoom.'”
This feedback reflects how structured participation helps maintain engagement during remote sessions.
Additionally, I use exit tickets at the end of each class session, which provide immediate feedback on lesson effectiveness and student comprehension.
Nexus: Do you have any testimonials or feedback from your students about their learning experiences that you can share with us?
Donatella: My students' feedback often reflects a transformation in their relationship with mathematics. Here are some comments from my Fall 2024 and Spring 2024 courses:
"Thank you so much, Professor, for a great semester! Truth be told, I have never been good at math, but your lessons helped break down that mental barrier for me."
"I'm much better at math than I imagined."
"Professor Delfino was very helpful, offering resources and thorough explanations with thought-out lesson plans, making sure each student is on track with interactive questions. The quizzes and exit tickets served as a great help in mastering the formulas."
Nexus: What best practices in teaching do you recommend to faculty?
Donatella: I recommend strategic planning and creating a culture of connection with students:
Course Design and Assessment Planning: Spend time developing assessment plans and grading rubrics. Structure assignments to ensure timely grading.
Frequent Low-Stakes Assessments: Regular, small assessments help students stay engaged and provide ongoing feedback opportunities.
Personal Connection: Show up before class starts and talk with students. These informal interactions create a more welcoming learning environment. You might also consider a "Getting to Know You" pre-course survey on Brightspace before the first meeting. Share summary results during the initial class to help students understand their peer group's characteristics.
In-Class Participation: Require substantive participation during class sessions to enhance engagement.
Nexus: What’s next in your field/industry?
Donatella: I am eager to explore how to use Generative AI as both a tutor and a teachable agent in my math classes. Having students teach concepts to AI will deepen their understanding of math, while AI tutoring can provide them with personalized support when they need it. This hands-on experience with AI tools will give our students a valuable edge in the workforce, where AI literacy is becoming essential across industries.
Nexus: Who has influenced your work as an educator?
Donatella: My teaching philosophy is grounded in mathematician Federico Ardila's principles of educational equity and accessibility. I believe that mathematical talent transcends geographical, demographic, and economic boundaries and am committed to creating empowering mathematical experiences.
Nexus: Do you have any hobbies or interests outside of your work that you'd like to share?
Donatella: I'm an avid sewist and plant enthusiast. I enjoy how creating home accessories and clothing combines the artistry of fabric and color selection with the precision of pattern-making and construction. I also care for about 20 houseplants, including an avocado plant I sprouted from seed.
