Students were encouraged to follow both instructors on Twitter and were asked to share aspects of the class using the social media site. Instructors regularly posted content and links relevant to the course and interacted with students, modeling professional social media interactions. Although the extent of student participation was limited, it was determined that this is a possible complementary outlet for class communication, sharing of information, and limited data gathering. In the lab courses, students were found to be more reticent to engage but did use the "follow" function to add the lab instructor to their Twitter networks. Lab and lecture courses were surveyed in order to determine factors affecting student engagement on social media. Results of the surveys and data collected in both courses are discussed with an emphasis on best practices.}, journal={JOURNAL OF CHEMICAL EDUCATION}, author={Frohock, Bram H. and Macallister, Cade A. and Gallardo-Williams, Maria T.}, year={2022}, month={Aug} } @article{gallardo-williams_2022, title={From hardship to scholarship}, volume={1}, ISSN={["2397-3358"]}, DOI={10.1038/s41570-021-00349-3}, abstractNote={While there is much of the last two years we may wish to forget, it is imperative that we share our pandemic chemistry teaching experiences.}, journal={NATURE REVIEWS CHEMISTRY}, author={Gallardo-Williams, Maria}, year={2022}, month={Jan} } @article{del negro_gallardo-williams_2022, title={Labapalooza: What Happens When Students Return to In-Person Laboratories After Taking Laboratories Online for a Year?}, volume={6}, ISSN={["1938-1328"]}, DOI={10.1021/acs.jchemed.2c00141}, abstractNote={Due to the COVID-19 pandemic, in-person undergraduate chemistry laboratories at North Carolina State University were not available to students during the 2020-2021 academic year and were replaced with online laboratories.

Students usually acquire this knowledge in General Chemistry and need to review it in preparation for Organic Chemistry. However, many students find the task of drawing Lewis structures to be challenging, and not all instructors can budget enough time in class to review this material when they start Organic Chemistry. To address this issue, we created a web application (web app; Lewis Structure Builder) that lets students review Lewis structures in their own time, allowing them to position individual atoms, build and break bonds, and get real-time feedback on the accuracy of their structures. The web app was designed to be intuitive, requiring very little training to use, and students could use desktops, laptops, or mobile devices to participate. In working through a sequence of target molecules to build, students had the freedom to try out different atomic structures to see what works and receive real-time feedback about their decisions. Upon successful completion of a molecule, students received visual and haptic feedback as a form of positive reinforcement. Afterward, students saw their solution next to the same molecule shown as an extended structure and as built using a model kit. A pilot study was conducted with 37 students who were enrolled in Organic Chemistry I. Participants were given an assessment to determine their level of proficiency in drawing Lewis structures, followed by an opportunity to use the web app and a post-test. After using the web app, 21% of the participants showed improved outcomes, and most students reported satisfaction with the user interface and perceived benefits from the experience.}, number={8}, journal={JOURNAL OF CHEMICAL EDUCATION}, author={Paye, Ciana L. and Dunnagan, Cathi L. and Tredwell, David A. and Gallardo-Williams, Maria T.}, year={2021}, month={Aug}, pages={2704–2708} } @article{gallardo-williams_dunnagan_2022, title={Designing Diverse Virtual Reality Laboratories as a Vehicle for Inclusion of Underrepresented Minorities in Organic Chemistry}, volume={99}, ISSN={["1938-1328"]}, DOI={10.1021/acs.jchemed.1c00321}, abstractNote={Equal access to an instructor’s time and attention can be a barrier experienced by many underrepresented minorities. An instructor’s own biases will determine the nature of their interaction with students, and even well-meaning instructors can interact with students in differential ways, which might prevent certain students from having access to the material in the class. This is an insidious problem, which may or may not be recognized in peer and student evaluations, and an issue that might escape self-reflection even in educators that are committed to diversity and inclusion. This issue conflates both actual and perceived biases, introducing a complex dynamic between instructor and student. Virtual reality (VR) provides an avenue to generate materials that can be used to enhance or replace classroom instruction with a great degree of realism. Our approach at NC State University was to design VR laboratories that were as inclusive and diverse as possible. This encompassed sourcing content and tapping talent from students that represented a broad range of races, gender identities, and ethnicities. These realistic simulations offer the advantage of minimizing instructor bias (since the instructor generates the material in the absence of the students) while offering students that might struggle with the instructor in a personal setting the opportunity to experience the best that the instructor has to offer. Analysis of the data collected in a user study of VR materials created for organic chemistry laboratories offers insights into the way that students interact with VR instructors. Comments provided by underrepresented minority students point to the perceived impartiality of the instructor, ability to engage with the material independently, and remote access as some of the desirable features of the experience.}, number={1}, journal={JOURNAL OF CHEMICAL EDUCATION}, author={Gallardo-Williams, Maria T. and Dunnagan, Cathi L.}, year={2022}, month={Jan}, pages={500–503} } @article{piontkivska_gassensmith_gallardo-williams_2021, title={Expanding Inclusivity with Learner-Generated Study Aids in Three Different Science Courses}, volume={98}, ISSN={["1938-1328"]}, DOI={10.1021/acs.jchemed.1c00373}, abstractNote={Note taking is a seemingly simple study strategy, yet as a source of learner-generated content its perceived effectiveness varies across subjects and from student to student, as not all students are able to create high-quality notes without guidance. While often advocated by the instructors, the use of notes as exam aids (whether used in open-books exams or not) is a pedagogical practice that has invited some controversy, but there are studies that justify the use of student-created reminder sheets by acknowledging that students must review the material in order to organize and create their study aids. Preparing for exams by actively developing formula sheets or other study aids assists students in studying, even if they are not consciously aware they are studying. We would like to suggest that modeling the process of creating successful study aids from class notes is an inclusive practice that leads to improved outcomes in low-performing students and increases their agency. Creating scaffolds for note taking, whether through sharing examples or prompting synthesis of information, allows for higher-quality note taking across all learners. We provide examples from three separate courses in which the instructors took this approach in widely different ways, and we offer a set of best practices for other instructors interested in using these resources in their own courses.}, number={10}, journal={JOURNAL OF CHEMICAL EDUCATION}, author={Piontkivska, Helen and Gassensmith, Jeremiah J. and Gallardo-Williams, Maria T.}, year={2021}, month={Oct}, pages={3379–3383} } @article{williams_gallardo-williams_griffith_bretz_2022, title={Investigating Meaningful Learning in Virtual Reality Organic Chemistry Laboratories}, volume={99}, ISSN={["1938-1328"]}, DOI={10.1021/acs.jchemed.1c00476}, abstractNote={Virtual reality (VR) lab experiences for organic chemistry were developed at NC State University as an accessibility tool for students who are unable to attend in-person laboratories due to disabilities, attendance challenges such as pregnancy or military deployment, or safety concerns. The resulting first-person VR experiences are immersive and realistic, with a virtual teaching assistant guiding the user along the steps required to complete the experiment, including feedback as needed. During the COVID pandemic, these laboratories replaced traditional face-to-face laboratories at NC State and several other universities. During the summer of 2020, we used the Meaningful Learning in the Laboratory Instrument (MLLI) to measure both the cognitive and affective dimensions of students' expectations of the virtual lab before the course and their experiences with virtual reality after completing the course. Students who completed virtual reality laboratories reported more positive affective experiences than they anticipated, including little frustration or confusion in the laboratory. © 2021 American Chemical Society and Division of Chemical Education, Inc.}, number={2}, journal={JOURNAL OF CHEMICAL EDUCATION}, author={Williams, Nicholas D. and Gallardo-Williams, Maria T. and Griffith, Emily H. and Bretz, Stacey Lowery}, year={2022}, month={Feb}, pages={1100–1105} } @article{box_paye_gallardo-williams_2021, title={Positive Feedback via Descriptive Comments for Improved Safety Inspection Responsiveness and Compliance}, volume={28}, ISSN={["1878-0504"]}, DOI={10.1021/acs.chas.1c00009}, abstractNote={The format of feedback can have a significant impact on the outcome of an evaluation. Checklists, a common tool in health and safety inspections, have limited potential to change practices and habits between utilizations because implicitly they are finite in terms of conveying priority or providing guidance on how to solve cited issues. In addition, they are vulnerable to variability in the thoroughness of application. In contrast, feedback in the form of unstructured descriptive comments has the potential to magnify existing strengths, which sustain an overall good practice between inspections if the comments include positive citations that are specific and detailed. Without inclusion of both positive feedback and unstructured descriptive comments to the standard, structured checklist, inspectors miss the opportunity to reinforce actions already being performed and the opportunity to build on the foundation of existing skill and knowledge.
