Raman spectroscopy based activities were developed and implemented into the first year
chemistry undergraduate curriculum. The implementation of these experiences and
experiments and the utility of Raman spectroscopy as a teaching tool to convey anchoring
chemistry concepts using a hands-on Raman spectroscopy based approach are discussed.
Fundamental principles of chemistry, such as the interaction of light with matter, molecular
bonding, equilibrium, and acid base reactions are facilitated through use of these Raman
spectroscopy based experiments and experiences. An assessment of student learning gains
as a result of participation in a Raman spectroscopy experience was also conducted and is
discussed.

An Organic Chemistry Lab experiment is being developed and adapted from work recently published by Maity and Lepore [1] investigating the cyclization of substituted β-alkynyl hydrazines to yield azaproline derivatives. The mechanism of this reaction is putatively driven by cation-π interaction of alkynyl hydrazine with a tetrabutylammonium ion. This experiment will present students with a cutting-edge research concept to explore the role of tetrabutylammonium in the cyclization of substituted β-alkynyl hydrazines. Reaction kinetics will be probed by thin-layer chromatography and azaproline derivative product(s) will be characterized by IR spectroscopy. Ultimately, our goal is to implement a modern research-based, cost-effective, and safe bioorganic experiment into Florida Atlantic University’s undergraduate Organic Chemistry Laboratory curriculum.

A web-based learning system for Organic Chemistry is being integrated into a Peer-Led Team Learning (PLTL) environment to restructure the existing Organic Chemistry I discussion (OrgoBOND) sections to enhance student learning, improve overall grades, and lower the Organic Chemistry I DFW rates. Students taking Organic Chemistry I are required to participate in a section of OrgoBOND utilizing the web-based learning system in a smaller classroom than in previous discussion sessions. Student performance will be compared to that of students in future semesters participating in the same small PLTL setting, but with traditional recitation format. The advantages of introducing a web-based learning system into PLTL discussion sessions are (1) providing “hints,” (2) offering multiple attempts per question, and (3) instant grading and feedback. The computer assignments are unique to each student and reflect the topic recently reviewed in lecture. We will report on the preliminary results from data being collected on student performance, satisfaction levels, and retention rate changes.

The navigational system at Florida Atlantic University Boca Raton campus does not provide efficient travel for visitors, students, and faculty. Results from a survey shows 8 out of 10 people are being misdirected around the Boca Raton campus causing delays, traffic, and frustration. The architectural design of the Boca Raton campus buildings makes navigating even more difficult because of their identical qualities. The directory maps on campus fail to inform current position, are visually overwhelming and are outdated. From the research collected, we will create a cohesive navigational system that makes travel easier for visitors, students, and faculty. The new navigational system will comprise of a redesigned directory, numeric building signage, route markers, and an instruction manual.
