Reconnecting Students and Faculty to Maximize Academic Integrity and Minimize Student Stress in the Virtual ClassroomParks, Samantha T. (Ed.)ABSTRACT The article documents faculty experiences with the shift online due to the pandemic and provides recommendations to science, technology, engineering, and mathematics (STEM) instructors. Over 100 faculty members were surveyed on these topics and contrasted with previously reported student experiences. The online shift changed how faculty administered exams, ran courses, and acted to ensure academic integrity. For example, when exams went online, 73% of faculty reported spending more time preventing cheating. Concerning academic integrity and stress, faculty and students agreed with the exception of a few notable disconnects. Students reported greater workloads in online classes, while faculty maintained that the shift online did not change student workloads. Students perceived more online cheating than faculty. Overall, there seems to be a significant disconnect regarding faculty not realizing how much their actions may encourage or discourage cheating. Few faculty (<15%) indicated that being a tough grader or having test times too short is a motivating factor, but over 55% of students reported that these motivate students to cheat. Conversely, over 60% of students reported respect for their professors discourages them from cheating, while only 37% of faculty indicated the same. Over 70% of faculty and students indicated that fear of gettingmore »Free, publicly-accessible full text available September 12, 2023
ABSTRACT The article documents students’ experiences with the shift online at the onset of the COVID-19 pandemic and provides informed recommendations to STEM instructors regarding academic integrity and student stress. Over 500 students were surveyed on these topics, including an open-ended question. Students experienced more stress and perceived a greater workload in online courses and therefore preferred in-person courses overall. Personal awareness of cheating during online exams is positively correlated with the proportion of cheating a student perceives. Fear of getting caught is the best cheating deterrent while getting a better grade makes cheating most enticing. Randomization of questions and answer choices is perceived as a highly effective tool to reduce cheating and is reported as the least stress-inducing method. Inability to backtrack and time limits cause students the most stress. Students report that multiple choice questions are the least effective question type to discourage cheating and oral exam questions cause the most stress. Use of camera and lockdown browser or being video- and audio- recorded caused the majority of student stress. Yet, nearly 60% agree that the combination of camera and lockdown browser is an effective deterrent. Recommendations: (i) Be transparent regarding academic dishonesty detection methods and penalties.

ABSTRACT The global COVID-19 pandemic left universities with few options but to turn to remote learning. With much effort, STEM courses made this change in modality; however, many laboratory skills, such as measurement and handling equipment, are more difficult to teach in an online learning environment. A cohort of instructors who are part of the NSF RCN-UBE funded Sustainable, Transformative Engagement across a Multi-Institution/Multidisciplinary STEM (STEM 2 ) Network (a working group of faculty from two community colleges and three 4-year universities) analyzed introductory biology and chemistry courses to identify essential laboratory skills that students will need in advanced courses. Seven essential laboratory proficiencies were derived from reviewing disciplinary guiding documents such as AAAS’s Vision and Change in Undergraduate Biology Education, the American Society for Microbiology’s Recommended Curriculum Guidelines for Undergraduate Microbiology Education , and the American Chemical Society’s Guidelines for Chemistry : data analysis, scientific writing, proper handling and disposal of laboratory materials, discipline-specific techniques, measurement, lab safety and personal protective equipment, and interpersonal and collaborative skills. Our analysis has determined that some of these skills are difficult to develop in a remote online setting but could be recovered with appropriate interventions. Skill recovery procedures suggested are a skillsmore »
We demonstrate that imidazole based π–π stacked dimers form strong and efficient conductance pathways in single-molecule junctions using the scanning-tunneling microscope-break junction (STM-BJ) technique and density functional theory-based calculations. We first characterize an imidazole-gold contact by measuring the conductance of imidazolyl-terminated alkanes ( im-N-im , N = 3–6). We show that the conductance of these alkanes decays exponentially with increasing length, indicating that the mechanism for electron transport is through tunneling or super-exchange. We also reveal that π–π stacked dimers can be formed between imidazoles and have better coupling than through-bond tunneling. These experimental results are rationalized by calculations of molecular junction transmission using non-equilibrium Green's function formalism. This study verifies the capability of imidazole as a Au-binding ligand to form stable single- and π-stacked molecule junctions at room temperature.
