Project Grant 2517612

The National Science Foundation Division of Undergraduate Education awarded the University of Texas Rio Grande Valley $182,858 on October 1, 2026, through the STEM Education program (CFDA 47.076) to design, test, and refine inquiry-oriented classroom lessons on sequences and series for second-semester calculus paired with Universal Design for Learning principles. The project will develop instructional materials freely available to educators and produce online instructor support resources that make lesson reasoning visible and adaptable to diverse classroom settings. The recipient will also establish a professional development workshop to prepare instructors to enact the lessons in their own courses. Work is performed in Edinburg, Texas, with a period of performance through September 30, 2029. The project targets the national interest by improving undergraduate calculus instruction so more students experience mathematics as a creative endeavor, with particular focus on the sequences and series unit as an opportunity for creative reasoning. Expected outcomes include freely distributed instructional materials and a growing network of calculus instructors prepared to teach using the developed approach.
