Dutton, Nicole A. M. – American Journal of Distance Education, 2023
An increase in online science course offerings requires a closer evaluation of the online laboratory experience. While it has been established that students can successfully learn from online laboratory simulations, there is a lack of knowledge regarding factors that impact student success. Grounded in the constructivist learning theory, a unique…

Kaylynn Imsande; Lucy McGuire; Luke Wheeler – American Biology Teacher, 2023
At a time when all course instruction had been moved online, it seemed wishful thinking for a group of undergraduate students to begin authentic, independent research. With curious, creative, and motivated mindsets; however, we learned not only that such research was possible during a global pandemic, but that it could provide vital learning…

Anderson, Laurel J.; Dosch, Jerald J.; Lindquist, Erin S.; McCay, Timothy S.; Machado, Jose-Luis; Kuers, Karen; Gartner, Tracy B.; Shea, Kathleen L.; Mankiewicz, Carol; Rodgers, Vikki L.; Saunders, Patricia A.; Urban, Rebecca A.; Kilgore, Jason S.; Powell, Amanda S.; Ramage, Benjamin S.; Steinweg, J. Megan; Straub, Jacob N.; Bunnell, Sarah L.; Witkovsky-Eldred, Marissa – Scholarship and Practice of Undergraduate Research, 2020
Multisite, course-based undergraduate research experiences (CUREs) in the Ecological Research as Education Network (EREN) were assessed for impacts on student learning of collaborative science skills using a survey that could serve as a starting point for a validated assessment instrument for multisite CUREs. Pretests/posttests were administered…

Pollock, David W.; Truong, Giovanna T.; Bonjour, Jessica L.; Frost, John A. – Journal of Chemical Education, 2018
Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

Chloe Wasendorf; Joshua W. Reid; Rebecca Seipelt-Thiemann; Z. T. Grimes; Brock Couch; Nick T. Peters; Julia Massimelli Sewall; Audrey L. McCombs; Patrick I. Armstrong; Nancy Boury – Journal of Biological Education, 2024
Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of…

Yu, Alder; Wisinski, Jaclyn; Osmundson, Todd; Sanderfoot, Anton; Cooper, Scott; Klein, Jennifer – Education Sciences, 2022
The COVID-19 pandemic ushered in an unprecedented period of both crisis and innovation in higher education. The shift to an online learning environment was particularly problematic for courses in which students learn disciplinary practices. Scientific practice requires hands-on training and collaborative engagement with instructors and peers,…

Jacobberger, Robert M.; Machhi, Rushad; Wroblewski, Jennifer; Taylor, Ben; Gillian-Daniel, Anne Lynn; Arnold, Michael S. – Journal of Chemical Education, 2015
Graphene's unique combination of exceptional mechanical, electronic, and thermal properties makes this material a promising candidate to enable next-generation technologies in a wide range of fields, including electronics, energy, and medicine. However, educational activities involving graphene have been limited due to the high expense and…

Hein, Sara M.; Kopitzke, Robert W.; Nalli, Thomas W.; Esselman, Brian J.; Hill, Nicholas J. – Journal of Chemical Education, 2015
A discovery-based Grignard experiment for a second-year undergraduate organic chemistry course is described. The exclusive Grignard reagent formed by the reaction of 1-bromo-4-fluorobenzene (1) with Mg is 4-fluorophenylmagnesium bromide (2), which is treated with either benzophenone or CO[subscript 2] to produce the corresponding fluorinated…

Kirk, John S.; Fahlman, Bradley D. – Journal of Chemical Education, 2020
Because of COVID-19 precautions, instructors worldwide were required to introduce a variety of virtual instruction modes to complete the Spring 2020 semester. Herein we describe parallel efforts in contextualized chemistry courses at two institutions--Carthage College and Central Michigan University. These courses are primarily designed for…

Bonjour, Jessica L.; Pitzer, Joy M.; Frost, John A. – Journal of Chemical Education, 2015
Mole to gram conversions, density, and percent composition are fundamental concepts in first year chemistry at the high school or undergraduate level; however, students often find it difficult to engage with these concepts. We present a simple laboratory experiment utilizing portable nuclear magnetic resonance spectroscopy (NMR) to determine the…

Lindstrom, Timothy; Middlecamp, Catherine – Journal of Chemical Education, 2017
In the undergraduate curriculum, chemistry and sustainability connect easily and well. Topics in chemistry provide instructors with opportunities to engage students in learning about sustainability; similarly, topics in sustainability provide instructors with opportunities to engage students in learning chemistry. One's own college or university…

Bosman, Lisa; Chelberg, Kelli; Winn, Ryan – Journal of STEM Education: Innovations and Research, 2017
Many barriers exist for American Indian students pursuing STEM degree programs. However, federally recognized Tribal Colleges and Universities (TCUs) are uniquely suited to overcome these barriers because of their shared mission to provide 21st Century educational opportunities for American Indian students. Qualitative and quantitative findings…

Ryan, Michael D.; Reid, Scott A. – Journal of Chemical Education, 2016
Despite much recent interest in the flipped classroom, quantitative studies are slowly emerging, particularly in the sciences. We report a year-long parallel controlled study of the flipped classroom in a second-term general chemistry course. The flipped course was piloted in the off-semester course in Fall 2014, and the availability of the…

Byars-Winston, Angela; Rogers, Jenna; Branchaw, Janet; Pribbenow, Christine; Hanke, Ryan; Pfund, Christine – CBE - Life Sciences Education, 2016
An important step in broadening participation of historically underrepresented (HU) racial/ethnic groups in the sciences is the creation of measures validated with these groups that will allow for greater confidence in the results of investigations into factors that predict their persistence. This study introduces new measures of theoretically…

Teplukhin, Alexander; Babikov, Dmitri – Journal of Chemical Education, 2015
In our three-dimensional world, one can plot, see, and comprehend a function of two variables at most, V(x,y). One cannot plot a function of three or more variables. For this reason, visualization of the potential energy function in its full dimensionality is impossible even for the smallest polyatomic molecules, such as triatomics. This creates…
