“…The development of CUREs has been successful, but adoption has been greater in the life sciences than in the physical sciences. , There are an increasing number of CUREs in the chemical literature, − but within chemistry, there is still limited awareness of many instructional practices, CUREs among them. Examples of both protocols as well as published data will improve awareness and thereby foster adoption of this practice .…”

An Inorganic Chemistry Laboratory Course as Research

A research-based inorganic chemistry laboratory course is described. Using the defined protocol of a course-based undergraduate research experience (CURE), students undertake a self-designed research project to identify new catalysts for the dehydrogenation of ammonia borane. Students select ligands and metals, prepare and characterize catalysts precursors, develop protocols for catalysts, and screen catalyst precursors. These activities are designed to align with the five components of a CURE (research activities, discovery, relevance, collaboration, and iteration), and this course is presented as one model from which individuals can develop CUREs at their own institutions. The students were assessed with the CURE survey, which showed gains in both research activities and understanding the nature of science.

“…In wet chemistry, students employ Schlenk techniques to prepare a ferricenium complex, cyclic voltammetry to evaluate redox properties of related compounds, and NMR spectroscopy to follow kinetics of exchange in a cobalt amine complex . Students also design a three-step synthesis of an organic compound and spend several laboratory periods working on the synthesis …”

Laboratory Curriculum for a Structure, Reactivity, and Quantitation Sequence in Chemistry

A novel laboratory curriculum is presented, developed around some common tasks of a laboratory researcher in chemistry: purification, synthesis, and measurement. The capstone of the sequence is an integrated laboratory, leading to a more independent research experience. Students who have completed this laboratory curriculum appear to perform comparably to previous students who completed a more traditional curriculum, based on their handling of American Chemical Society Exam questions and career placement. Introduction of the new curriculum has coincided with increased numbers of majors as well as increased participation in research, but attributing causation is complicated by the coincidental introduction of a new scholarship program.

“…This format of detailed instructions and known outcomes does not best model the work of practicing STEM scientists. While openended chemical synthesis activities have been developed for the undergraduate classroom, 12 these experiences are not yet widely available to younger students. However, there is a trend in K−12 schools toward student-centered learning.…”

Design of a Guided Inquiry Classroom Activity to Investigate Effects of Chemistry on Physical Properties of Elastomers

et al. 2021

Typical organization of science and mathematics K12 education divides subjects into discrete courses. However, science and engineering are highly interdisciplinary fields. To better equip students to engage in the interdisciplinary nature of real-world STEM research and practice, projects can be used to highlight the interconnectivity of core subjects. Here, we present an exploratory, guided inquiry classroom research project. This work details student-led experiments combining physics and chemistry principles to fabricate silicone bouncy balls and analyze resulting mechanochemical relationships in these elastomeric materials. In this project, students embodied researchers to uncover foundational relationships among chemistry, physics, and mathematics. To do this, students used silicone kits to design an array of polymer formulations resulting in bouncy balls of varying stiffnesses. Students aimed to answer a physics-based research question using chemistry and mathematics. The resulting data was used to discuss the effect of polymer chemistry on the behavior of the bouncy balls. This exercise serves to combine hands-on fabrication methods with quantitative analysis, using experimental methods of varying costs and complexities that can be tailored to instructor time and budget. The project presented here is appropriate for upper-level high school students or first-year undergraduates. The pedagogical goal of the work is to empower students to realize and use connections between chemistry, physics, polymer science, and engineering to understand the process of material design and selection.
