Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Feminist Biology: Towards Gender Equity In The Biology Curriculum, Nicole Danos, Carla Y. Bonilla, Sofia Leung

Feminist Pedagogy

The current curriculum in STEM is a product of historically unequal representation of genders in the science community. As a result, most attention has been given to male biology, creating a knowledge gap that has affected our social and political perspectives, such as an underinvestment in women’s health research. Feminist biology seeks to provide equal time and weight to the impact of sex as a biological factor, using inclusive definitions of biological sex that go beyond the male/female binary. Feminist pedagogy is a method of teaching that involves engaged learning and reflection in order to create a community of learners …

Centering Equity In Stem Teaching: Stem Ideas That Change The World, Ileana Vasu

Feminist Pedagogy

No discussion on equity/inequity makes sense without bringing power into that discussion. As instructors we need to ask questions such as “who decides and controls what knowledge is”, “whose identities are empowered and whose are erased”, “who has access and opportunity and who doesn’t”. Traditional teaching in STEM, including mathematics, assumes knowledge is objective, transmittable, repeatable to everyone. When educators follow a traditional curriculum, just like their teachers before them, they do so thinking their methods ensure equality and objectivity. These practices not only deny the role that Western patriarchal cultures have played in creating these so-called equitable practices, but …

A Professional Development Program For Science Adjunct Faculty: The Mentoring-Learning Community (Mlc), Linda B. Purvis, Jason D. Lang, Julie A. Luft

Georgia Journal of Science

Institutions of higher education have become increasingly dependent on adjunct faculty. These faculty members are often unfamiliar with current teaching strategies emphasizing an active learning approach. To support science adjunct faculty in learning about active learning, a professional development program was designed and implemented by the authors of this study, the Mentoring-Learning Community. The Mentoring-Learning Community program design was informed by literature regarding the use of professional development programs that focused on adjunct faculty. To determine the impact of this program, participants in the Mentoring-Learning Community were observed and interviewed over one semester. Mentoring-Learning Community participants transformed through all three …

Analysis Of Attitudinal Student Learning Benefits From A Course-Based Undergraduate Research Experience (Cure) Adapted For Online Format, Ambika Kapil, Luis C. Gonzalez Isoba, Niraj Pathak, Arthur Sikora, Santanu De

FDLA Journal

Course-based Undergraduate Research Experiences (CUREs) are an increasingly utilized model for exposing students to research. The lack of robust assessments is a major hurdle to wider adoption of CUREs. The Coronavirus Infectious Disease 2019 (COVID-19) pandemic necessitated a drastic shift of in-person courses to the online format. Using the Participant Perception Indicator (PPI) survey, we measured students’ self-reported changes in learning from such a biochemistry course at a large university in south Florida based on the Biochemistry Authentic Scientific Inquiry Lab (BASIL) model. By doing this, we were able to better understand the student-benefits of CUREs and how these benefits …

The results of this work may provide aid to teachers, parents, administrators, and even students seeking to find ways to increase student motivation and performance in the STEM subjects. Additionally, this work may be of interest to advocates of the arts. This quantitative correlational study was …

Challenge-Based Learning & Steam Curriculum, Diana Lockwood

The STEAM Journal

STEAM education is being integrated into elementary schools as a way to engage more students in creativity, hands-on learning, and problem-based learning also referred to as Challenge-Based-Learning (CBL). This article focuses on elementary educators’ curriculum design for STEAM and presenting students with open-ended questions phrased as a challenge as a way to raise student interest and achievement (DeJarnette, 2018; Hunter-Doniger, 2018). When students received challenges to solve, they felt more open to sharing their ideas since there was more than one potential right answer (DeJarnette, 2018; Drake, 2012). When implementing CBL, teachers act as facilitators using a constructivist approach as …

Students Interest And Thoughts On Stem, Chrisitine Girtain

STEM Month

I am Juan Sebastian Bohorquez Mora, I am a sophomore student at Toms River High School North. I am interested in biofuels because I believe they are a good option to replace fossil fuels. I am also interested in duckweed because biofuels are made out of crops, and people need to eat those crops. That’s when duckweed comes in and it can be used as a feedstock for ethanol production which is a biofuel. Bioethanol is a type of biofuel and it is derived from the corn’s starch. Instead of making ethanol from the corn’s starch, we can use duckweed …

Qualitative Analysis Of A Resource Management Model And Its Application To The Past And Future Of Endangered Whale Populations, Glenn Ledder

CODEE Journal

Observed whale dynamics show drastic historical population declines, some of which have not been reversed in spite of restrictions on harvesting. This phenomenon is not explained by traditional predator prey models, but we can do better by using models that incorporate more sophisticated assumptions about consumer-resource interaction. To that end, we derive the Holling type 3 consumption rate model and use it in a one-variable differential equation obtained by treating the predator population in a predator-prey model as a parameter rather than a dynamic variable. The resulting model produces dynamics in which low and high consumption levels lead to single …

The Carbon Price Equivalent: A Metric For Comparing Climate Change Mitigation Efforts Across Jurisdictions, Gabriel Weil

Dickinson Law Review (2017-Present)

Climate change presents a global commons problem: Emissions reductions on the scale needed to meet global targets do not pass a domestic cost-benefit test in most countries. To give national governments ample incentive to pursue deep decarbonization, mutual interstate coercion will be necessary. Many proposed tools of coercive climate diplomacy would require a onedimensional metric for comparing the stringency of climate change mitigation policy packages across jurisdictions. This article proposes and defends such a metric: the carbon price equivalent. There is substantial variation in the set of climate change mitigation policy instruments implemented by different countries. Nonetheless, the consequences of …

Visual Arts Enhance Instruction In Observation And Analysis Of Microscopic Forms In Developmental And Cell Biology, Max Ezin, Christina Noravian, Amira Mahomed, Adam Lyle, Aveleen Gill, Tamira Elul

The STEAM Journal

Two important skills for scientists in developmental and cell biology, as well as in fields such as neurobiology, histology and pathology, are: 1) observation of features and details in microscopic images of cells, and 2) quantification of cellular features observed in microscopic images. However, current training in developmental and cell biology does not emphasize observation and quantitative analysis of microscopic images, and it is unclear how best to teach students these skills. Here, we describe our experiences applying visual artistic approaches to instruct undergraduate and graduate students in how to observe and analyze cellular forms in microscopic images. At Loyola …

The holistic analysis combining the three stakeholders’ perspectives would help elucidate significant contemporary aspects impacting the fields. The goal is to further …

Extending Power Series Methods For The Hodgkin-Huxley Equations, Including Sensitive Dependence, James S. Sochacki

CODEE Journal

A neural cell or neuron is the basic building block of the brain and transmits information to other neurons. This paper demonstrates the complicated dynamics of the neuron through a numerical study of the Hodgkin-Huxley differential equations that model the ionic mechanisms of the neuron: slight changes in parameter values and inputted electrical impulses can lead to very different (unexpected) results. The methods and ideas developed for the ordinary differential equations are extended to partial differential equations for Hodgkin-Huxley networks of neurons in one, two and three dimensions.

This piece will look at regional and federal regulations and assess the increased rate of forest fires and the grave public health concerns from stagnant smoke specifically …

Factors That Influence Persistence Of Biology Majors At A Hispanic-Serving Institution, Shetay Ashford-Hanserd, Kristy Daniel, Dana M. García, Jenn L. Idema

Journal of Research in Technical Careers

To promote diversity within the science, technology, engineering, and mathematics (STEM) workforce, we must identify factors that influence or hinder historically underrepresented minority (URM) students’ persistence to degrees in STEM. We documented potential factors that influence students’ persistence in an undergraduate biology program and created a 14-item, Likert-scale instrument. We recruited 137 undergraduate biology majors at a Hispanic-serving institution in Texas to report which factors they found influential in their decision to remain enrolled in their degree programs. We used a modified social cognitive career theory model of career choice to guide interpretation of the reported influences and identify patterns …

The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De

FDLA Journal

Stimulating girls’ interest in science, technology, engineering and mathematics (STEM) when they are in school, and sustaining that interest, is critical in motivating girls to choose STEM-related disciplines in higher education and enter STEM careers. Research indicates that girls show an interest in STEM until about 11-12 years of age, but this starts to wane by the time they are 15-16 years. Thus, there is a clear need to focus on sustaining the interest of girls in STEM at middle or high school levels. Research has shown that one of the main drivers that impact girls’ interest in STEM is …

Making 3d Laser Cut Stratigraphic Audio-Responsive Tactile Templates, Michael A. Kolitsky

Journal of Science Education for Students with Disabilities

The geologic method of stratigraphy which studies the structure of the earth by making layers was employed with 3D laser cutting techniques to make more easily defined tactile regions in templates of cells, tissues and anatomic regions containing muscles and bones. Templates were made audio responsive by hand-drilling a small hole in a template and filling that hole with conductive electric paint. A finger touch to the template top side now carries a charge similar to an electric circuit to the template bottom side resting on the surface of an iPad or iPad Pro where an audio button produces audio …

Aligning Best Practices In Student Success And Career Preparedness: An Exploratory Study To Establish Pathways To Stem Careers For Undergraduate Minority Students, Kimberly D. Kendricks, Anthony A. Arment, K. V. Nedunuri, Cadance A. Lowell

Journal of Research in Technical Careers

Undergraduate minority retention and graduation rates in STEM disciplines is a nationally recognized challenge for workforce growth and diversification. The Benjamin Banneker Scholars Program (BBSP) was a five-year undergraduate study developed to increase minority student retention and graduation rates at an HBCU. The program structure utilized a family model as a vehicle to orient students to the demands of college. Program activities integrated best K-12 practices and workforce skillsets to increase academic preparedness and career readiness. Findings revealed that a familial atmosphere improved academic performance, increased undergraduate research, and generated positive perceptions of faculty mentoring. Retention rates among BBSP participants …

Brave Spaces: Augmenting Interdisciplinary Stem Education By Using Quantitative Data Explorations To Engage Conversations On Equity And Social Justice, John R. Jungck, Jon Manon

Numeracy

In workshops and courses involving in-service teachers, participating teachers can engage in problem posing and exploration of difficult issues when they are asked to quantitatively model alternative scenarios, statistically analyze complex data, and visualize these data in multiple formats. Subsequent to these activities, discussions of sensitive issues, some even considered taboo in classrooms, can open up “brave spaces” in these teachers’ classrooms. Without coaching through elaborate facilitation strategies, the in-service teachers grappled openly with the nuances of such difficult issues and raised many alternatives involving quantitative reasoning as well as considering biological, cultural, economic, social, and political factors influencing social …

Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi

Journal of the Iowa Academy of Science: JIAS

We present spectroscopy that confirms periodic Doppler-shifts along with photometry that reinforces a lack of eclipsing in the double-lined spectroscopic binary 57 Cygni. Our spectroscopy concentrates on a range encompassing H-alpha and the helium 667.8 nm line, where we find Doppler-shifts of both stars resolved in the helium line but less so in the broader H-alpha profile. Although we find the radial velocities derived from both lines reasonably consistent, we retained only the helium-line derived velocities for sinusoidal curve-fits to the orbital dependence. The fit-amplitudes specify the ratio of the stellar masses as 1.03 ± 0.05, in agreement with previous …

How Do Former Undergraduate Mentors Evaluate Their Mentoring Experience 3-Years Post-Mentoring: A Phenomenological Study, Kari L. Nelson, Christine E. Cutucache

The Qualitative Report

This phenomenological study involves a unique, longitudinal assessment of the lived experiences of former undergraduate mentors (n=7) in light of their current experiences (i.e., career or advanced schooling). The objective of a phenomenological study is to engage in in-depth probing of a representative number of participants. Specifically, we followed up with graduates of the Nebraska STEM 4U (NE STEM 4U) intervention 3 years post-program, with the overall goal of describing the mentors’ experiences using the lens of their current experiences. This type of longitudinal perspective of mentoring is greatly lacking in the current literature. At the time of the interviews, …

Parts Of The Whole: Why I Teach This Subject This Way, Dorothy Wallace

Numeracy

The importance of mathematics to biology is illustrated by search data from Google Scholar. I argue that a pedagogical approach based on student research projects is likely to improve retention and foster critical thinking about mathematical modeling, as well as reinforce quantitative reasoning and the appreciation of calculus as a tool. The usual features of a course (e.g., the instructor, assessment, text, etc.) are shown to have very different purposes in a research-based course.
