Biography

David has been involved in development and assessment of new learning technologies for over two decades. He is primary author of the Open Learning Initiative (OLI) general chemistry course, which is designed for use in blended course environments that smoothly integrate online and in-person learning. He also heads the ChemCollective. which makes virtual laboratory activities freely available to classrooms around the world. His current research on learning examines the ways students learn chemistry and the degree to which blended course environments help close performance gaps for underserved populations. He also considers the use of machine learning in chemistry.

Universities Partner To Make Chemistry More Equitable

Carnegie Mellon University  online

2022-06-08

David Yaron(opens in new window), professor of chemistry at CMU, has been developing chemistry courseware for decades.

"Our courseware supports new kinds of synchronous learning activities, especially improving instructor interactions with students and supporting better peer-to-peer learning opportunities. Ongoing research and partner feedback show that these kinds of interactions can be a powerful force for advancing more equitable outcomes, and I’m excited at this chance to accelerate that work," Yaron said.

Learning Engineering in Action

Carnegie Mellon University  online

David Yaron, a professor of chemistry in the Mellon College of Science, also talked about his use of the OLI platform in his courses. Before the pandemic, he created a virtual lab environment so that students could practice designing and conducting experiments without having to go to lab. This semester, it has become invaluable. In particular, it helps students prepare for the time they have together in class.

“What we’re aiming for is an experience for the student, where they get to spend their own time coming up to speed on what we’re going to do in person. This is a technique called flipping the classroom, where students do things online that prepare them for class,” Yaron said. “With OLI, we’ve created materials that everyone can use online.”

The Open-Response Chemistry Cognitive Assistance Tutor System: Development and Implementation

Journal of Chemical Education

2022

This report showcases a new type of online homework system that provides students with a free-form interface and dynamic feedback. The ORCCA Tutor (Open-Response Chemistry Cognitive Assistance Tutor) is a production rules-based online tutoring system utilizing the Cognitive Tutoring Authoring Tools (CTAT) developed by Carnegie Mellon University. In this report, we discuss the interface design and the production rules that allow for a multitude of chemistry calculations to be solved in a wide variety of ways by students. We discuss improvements of the software, already implemented or planned for the future, based on think aloud/interviews with students.

Design, synthesis, and properties of a six-membered oligofuran macrocycle

Organic Chemistry Frontiers

2021

Herein, we present the synthesis and properties of an ester-functionalized macrocyclic sexifuran (C6FE). This molecule was prepared in a single step from a furan-3-carboxylate dimer using a commercially available palladium catalyst (SPhos-Pd-G3) and isolated in 34% yield. DFT calculations predict the macrocyclic ring is planar, with minimal ring strain. The macrocycle is partially crystalline, as evidenced by powder X-ray diffraction patterns. Furthermore, the solid-state organization can be altered by modification of the ester side-chain. C6FE can also undergo two electron oxidation and reduction in solution as evidenced by cyclic voltammetry. Quantum chemical investigations revealed how aromaticity along the entire sexifuran macrocycle may play a role in the reversible electrochemistry.

Making Lemonade out of Lemons: Supporting Adoption of Evidence-Based Practices in Response to Educational Disruptions

Journal of Chemical Education

2020

Effective diffusion of educational innovations is essential for evidence-based practices to have broad impacts on student learning. One of the barriers to such diffusion is the large inertia associated with changing one’s teaching practices. Educational disruptions, such as COVID-19, may lower this barrier by making business-as-usual no longer feasible. Here, we reflect on the ways in which an online community, designed to promote diffusion of educational innovation, supported Advanced Placement (AP) Chemistry teachers in the rapid transition to online instruction necessitated by the pandemic. The lessons learned from supporting teachers as they responded to the pandemic may provide insights into how to better promote and support adoption of reformed teaching strategies.
