Examining STEM Learning Motivation Challenges in Undergraduate Students During the COVID-19 Pandemic

The COVID-19 pandemic disrupted global educational systems with institutions transitioning to e-learning. Undergraduate STEM students complained about lowered motivation to learn and complete STEM course requirements. To better prepare for more effective STEM education delivery during high-risk conditions such as pandemics, it is important to understand the learning motivation challenges (LMCs) experienced by students. As part of a larger national research study investigating decision-making in undergraduate STEM students during COVID-19, the purpose of this research is to examine LMCs experienced by undergraduate STEM students. One hundred and ninety students from six U.S. institutions participated in Qualtrics-based surveys. Utilizing a five-point Likert scale, respondents ranked the extent to which they agreed to LMC statements. Using Qualtrics Data Analysis tools and MS Excel, data from 130 useable surveys was analyzed utilizing descriptive and inferential statistics. Results revealed that regardless of classification, GPA, age, or race, STEM students experienced LMCs. The top five LMCs were: (1) Assignment Overloads;(2) Lack of In-Person Peer Interactions;(3) Uncaring Professors;(4) Lack of In-Person Professor Interactions;and (5) Lack of In-Person Laboratory Experiences. Significant relationships existed between three characteristics (GPA, classification, and age) and few LMCs to include assignment overloads. Students tended to attribute lowered motivation to Institutional and Domestic challenges which were typically out of their control, rather than to Personal challenges which were typically within their control. Crosstab analysis suggested that Sophomores, Asians, as well as students with GPAs between 2.00 and 2.49 and aged 41 to 50 years may be the most vulnerable due to higher dependence on traditional in-person STEM educational environments. Early identification of the most vulnerable students should be quickly followed by interventions. Increased attention towards sophomores may reduce exacerbation of potential sophomore slump and middle-child syndrome. All STEM students require critical domestic, institutional, and personal resources. Institutions should strengthen students' self-regulation skills and provide increased opportunities for remote peer interactions. Training of faculty and administrators is critical to build institutional capacity to motivate and educate STEM students with diverse characteristics in e-learning environments. Pass/fail policies should be carefully designed and implemented to minimize negative impacts on motivation. Employers should expand orientation and mentoring programs for entry-level employees, particularly for laboratory-based tasks. Research is needed to improve the delivery of STEM laboratory e-learning experiences. Findings inform future research, as well as best practices for improved institutional adaptability and resiliency. These will minimize disruptions to student functioning and performance, reduce attrition, and strengthen progression into the STEM workforce during high-risk conditions such as pandemics. With caution, findings may be extended to non-STEM and non-student populations. © American Society for Engineering Education, 2022

Work in Progress: Faculty Perceptions of STEM Student and Faculty Experiences during the Covid-19 Pandemic: A Fall 2020 Qualitative study

COVID-19 is a continuing global pandemic causing significant changes and modifications in the ways we teach and learn here in the U.S as well as around the world. Most universities, faculty members, and students modified their learning system by incorporating significant online or mixed learning methods/modes to reduce in person contact time and to reduce the spread of the virus. Universities, faculty and students were challenged as they adapted to new learning modules, strategies and approaches. This adaption started in the Spring of 2020 and has continued to date through the Spring of 2022. The main objective of this project was to investigate faculty perception of STEM student experiences and behavior during the Fall 2020 semester as compared to the Spring 2020 semester as COVID-19 impacts were prolonged. Through a qualitative methodology of zoom interviews administered to 32 STEM faculty members across six U.S. Universities nationwide and a theming scheme, the opinion and narratives of these faculty members were garnered in a round one and round two sets of interviews, in Summer 2020 and then in Spring 2021 (following the semesters of interest). Some of the main new themes that were detected in faculty interviews during the Fall 2020 semester and which reflect faculty perceptions are represented as follow: COVID-19 impact on student and faculty motivation, COVID-19 impacts on labs and experiential learning, COVID-19 impact on mental health, COVID-19 impact on STEM students' involvement in STEM experiential learning opportunities and research. Other previous themes detected and which are revisited to analyze major differences with those themes obtained during the Spring 2020 are presented and not limited to: extra efforts from professors, student cheating behavior, cheating factors and prevention, student behavioral and performance changes, student struggles and challenges, University response and efforts to the COVID-19 pandemic. We explored the differences in these themes between the semesters to look at noticed adaptations and modifications. Presented will also be recommendations to improve student and faculty motivation along with strategies to enhance the student learning experience during the COVID-19 pandemic. We report on common findings and suggest future strategies. © American Society for Engineering Education, 2022.

Ethnomedicinal, phytochemistry and pharmacological actions of leaf extracts of Spondias mombin: a narrative review

Spondias mombin is one of the species belonging to the (Family: Anacardiaceae), its ethnomedicinal uses may be justified through many studies that reported potential pharmacological properties due to its phytochemical compounds. This review aimed at examining the ethnomedicinal uses, phytochemical compounds and pharmacological properties of S. mombin leaf extracts on the African continent, to justify its use in the management and/ or treatment of viral infections and cancers. Electronic databases such as Google Scholar, SciHub, PubMed and Science Direct with search dates between 1999 and 2019 were used. Findings from this review confirm the ethnomedicinal uses, of decoctions and infusions of S. mombin leaf extracts for management diseases such as malaria, sore throat, and inflammation disorders;studies confirmed the presence of phytochemical compounds such as Geraniin, 2-O-Caffeoyl-(+)-allohydroxycitric acid, Quercetin-3-O-beta-D-glucopyranoside and pelandjuaic acid, responsible for the antiviral and chemotherapeutic properties. However, there is a need for bio-assay guided extractions, isolation, identification and characterization of phytochemical compound(s) in the leaf extracts of S. mombin that may be responsible for antiviral and anticancer activity. Investigations of the pharmacological action, in silico and in vitro studies of known and /or newly isolated compounds are warranted in the management and /or treatment of viral infections such as, Severe Acute Respiratory Syndrome Coronavirus 2, and cancers to justify the use of leaf extracts of S. mombin on the African continent for the management of viral infections and or cancer.

An Examination of Professor-Student Interactions, Stem Learning Challenges, and Student Adaptation Decisions During Covid-19 Pandemic

The COVID-19 pandemic transformed STEM learning environments across U.S. institutions. However, the impact of this pandemic on learning and decision-making in students are yet to be fully understood. It is important to gain insights into student experiences during COVID-19 pandemic so that student and institutional resiliency can be improved during future pandemics. This research is part of a larger nationwide inductive research project with the purpose of developing theories to explain the learning experiences and decisions of undergraduate STEM students during the COVID-19 pandemic. A mixed-methods approach with purposive sampling was utilized to enroll 63 undergraduate STEM students from six U.S institutions. Data was collected through recruitment surveys, academic transcripts, and interviews. One-hour ZOOM interviews, gave research participants the opportunity to narrate their salient STEM learning experiences during the spring 2020 semester. Data was analyzed using the NVivo qualitative analysis software and Microsoft Excel for coding, categorizing, memo-ing, constant comparative analysis, and theme development. Also, Microsoft Excel was used to analyze demographic data from recruitment surveys and GPA data from the academic transcripts. Results from the analysis of 30 coded interview transcripts revealed an emergent theme - Professor-Student Interactions Impact Learning and Adaptation Decisions. The three key categories of this theme are: Professor-Student Interactions and Learning Challenges;Adaptation Decisions;and STEM Performance. The seven categories of Professor-Student Interactions are coded as: Online Instructional Delivery Methods;Professor Caring Attitudes;Professor Leniency;Professor Availability;Student Workloads;Professor Technology Proficiency;and Professor Teaching Resources. Positive professor-student interactions improve student learning experiences. Negative professor-student interactions worsen student learning challenges and are coded as: Illusion of Time, Procrastination;Lack of Focus;Challenge of Asking Questions;Poor Understanding;Poor Quality Assignments;Poor Intermediate Grades;Stresses;and Lowered Motivation. While most research participants experienced high stresses, a few of them experienced low or no stresses. To minimize the impact of COVID-related learning challenges on their STEM learning and performance, research participants made effective adaptation decisions coded as: Refined Scheduling;Alternate Learning Resources;Professor Office Hours;Teaching Assistants;Peer Collaboration;Relaxation Strategies;and Pass/Fail Options. Compared to the fall 2019 GPAs, the improved spring 2020 GPAs of research participants may be partially attributed to professor leniency, pass/fail option, and cheating. Findings indicate that while STEM professors were adjusting to COVID-modified teaching and learning environments, many STEM students were developing a sense of self-discipline, self-teaching, and independence. They relied on both professor and non-professor generated resources to improve their own STEM learning and performance. Lessons learned and best practices for improved professor-student interactions and student adaptation decisions are discussed for potential replication in STEM communities for improved adaptability and resiliency during future pandemics. Future research will focus on quantifying the long-term effect of the COVID-19 pandemic on STEM performance. © American Society for Engineering Education, 2021

Faculty Perceptions of STEM Student and Faculty Experiences During the COVID-19 Pandemic: A Qualitative Study (WIP)

The recent outbreak of COVID-19, considered as being a lethal pandemic by the World Health Organization, has caused profound changes in the educational system within the U.S and across the world. Overnight, universities and their educators had to switch to a largely online teaching format, which challenged their capacity to deliver learning content effectively to STEM students. Students were forced to adapt to a new learning environment in the midst of challenges in their own lives due to the COVID-19 effects on society and professional expectations. The main purpose of this paper is to investigate faculty perceptions of STEM student experiences during COVID-19. Through a qualitative methodology consisting of one-hour zoom interviews administered to 32 STEM faculty members from six U.S. Universities nationwide, faculty narratives regarding student and faculty experiences during COVID-19 were obtained. The qualitative research approach involved identifying common themes across faculty experiences and views in these narratives. Some of the categories of emerging themes associated with faculty perceptions on student and faculty experiences included: student struggles and challenges, student cheating and the online environment, faculty and student adaptability, faculty and student needs and support, and university resources and support. Best practices to facilitate online teaching and learning employed by STEM faculty were also discussed. Key findings revealed that students and faculty had both positive and negative experiences during COVID-19. Additionally, there was a greater need for consistent policies to improve the online student learning experiences. Recommendations to improve STEM student experiences include increased institutional resources and collaboration between faculty and the university administrators to provide a coherent online learning environment. Preliminary findings also provide insights to enhance institutional adaptability and resilience for improving STEM student experiences during future pandemics. Future research should continue to explore institutional adaptation strategies that enhance STEM student learning during pandemics. © American Society for Engineering Education, 2021
