Nature Of Problem-Solving Skills For 21st Century Stem Learners: What Teachers Need To Know, Paul Nnanyereugo Iwuanyanwu Nov 2020

Nature Of Problem-Solving Skills For 21st Century Stem Learners: What Teachers Need To Know, Paul Nnanyereugo Iwuanyanwu

Journal of STEM Teacher Education

Since the emergence of the fourth industrial revolution which calls for a new model of learning for the twenty-first century learners, it has been argued that the nature of problems that learners must solve in science, technology, engineering and mathematics (STEM) must also be transformed to enable new forms of learning skills that are needed to tackle complex global challenges. However, the question of how best to teach these skills purposefully and explicitly is largely overlooked. STEM education reformers recognize that the lecture method or traditional method of teaching is highly ineffective for teaching twenty-first century competencies and skills that …

Finding Community And Overcoming Barriers: Experiences Of Queer And Transgender Postsecondary Students In Mathematics And Other Stem Fields, Elizabeth Kersey, Matthew Voigt Oct 2020

Finding Community And Overcoming Barriers: Experiences Of Queer And Transgender Postsecondary Students In Mathematics And Other Stem Fields, Elizabeth Kersey, Matthew Voigt

Publications

Although there is little research on the experiences of queer and/or transgender postsecondary students in science, technology, engineering, and mathematics (STEM) fields, we can infer from current literature that these subjects may be less welcoming than the humanities and social sciences. We conducted two studies to investigate this possibility: (1) a narrative inquiry study with postsecondary transgender students and (2) a grounded theory narrative study with undergraduate queer students. Transgender students who had transitioned indicated that they were subjected to lower expectations when presenting as female, but transgender women experienced this change as positive, since their treatment by others was …

Stem Laboratory Safety On A Shoestring, Emily K. Faulconer Oct 2020

Stem Laboratory Safety On A Shoestring, Emily K. Faulconer

Publications

Classroom laboratory activities promote learner development in scientific reasoning and interest in science. Learner safety is a critical concern. Many states have adopted OSHA standards (e.g. The Laboratory Standard 29 CFR 1910.1450 or Hazard Communication Standard 29 CFR 1910.1200) or developed their own standards to protect public school teachers and staff, but these do not extend to students.

Psychology Faculty Research

National efforts to improve equitable teaching practices in biology education have led to an increase in research on the barriers to student participation and performance, as well as solutions for overcoming these barriers. Fewer studies have examined the extent to which the resulting data trends and effective strategies are generalizable across multiple contexts or are specific to individual classrooms, institutions, or geographic regions. To address gaps in our understanding, as well as to establish baseline information about students across contexts, a working group associated with a research coordination network (Equity and Diversity in Undergraduate STEM, EDU-STEM) convened in Las Vegas, …

An Investigation Of How Environmental Science Textbooks Link Human Environmental Impact To Ecology And Daily Life, Yael Wyner, Rob Desalle Oct 2020

An Investigation Of How Environmental Science Textbooks Link Human Environmental Impact To Ecology And Daily Life, Yael Wyner, Rob Desalle

Publications and Research

Making direct connections between humanity and the environment is of ever-increasing importance in the context of today’s environmental crisis. We used qualitative content analysis of precollege- and college-level introductory environmental science textbook case studies to study how they portray humanity’s link to the environment. We assessed case studies for how specific and data rich they are and for how they link together daily life, human impact, and ecological interactions. We found that, for many textbooks, case study stories were vaguely drawn and included few data. We also found that, for all textbooks, case studies almost always described human impacts without …

Individuals who identify as lesbian, gay, bisexual, transgender, queer, and otherwise non-straight and/or non-cisgender (LGBTQ+) have often not felt welcome or represented in the biology community. Additionally, biology can present unique challenges for LGBTQ+ students because of the relationship between certain biology topics and their LGBTQ+ identities. Currently, there is no centralized set of guidelines to make biology learning environments more inclusive for LGBTQ+ individuals. Rooted in prior literature and the collective expertise of the authors who identify as members and allies of the LGBTQ+ community, we present a set of actionable recommendations to help biologists, biology educators, and biology …

Relative Impacts Of Different Grade Scales On Student Success In Introductory Physics, David J. Webb, Cassandra A. Paul, Mary A. Chessey Aug 2020

Relative Impacts Of Different Grade Scales On Student Success In Introductory Physics, David J. Webb, Cassandra A. Paul, Mary A. Chessey

Faculty Publications

In deciding on a student’s grade in a class, an instructor generally needs to combine many individual grading judgments into one overall judgment. Two relatively common numerical scales used to specify individual grades are the 4-point scale (where each whole number 0–4 corresponds to a letter grade) and the percent scale (where letter grades A through D are uniformly distributed in the top 40% of the scale). This paper uses grading data from a single series of courses offered over a period of 10 years to show that the grade distributions emerging from these two grade scales differed in many …

Student Perceptions Of Their Undergraduate Science Laboratories, Eva N. Nyutu Aug 2020

Student Perceptions Of Their Undergraduate Science Laboratories, Eva N. Nyutu

Dissertations

The science laboratory learning environment has been a distinctive area in science education since the 19th century. The science laboratory environment has been examined extensively at the high school level using the Science Laboratory Environment Inventory (SLEI). There are, however, very few studies about the science laboratory environment done at the college level. An instrument that may be helpful for college instructors is one that assesses the degree to which students perceive the laboratory as intended by their science instructors. An examination of the literature indicated that there are no validated and reliable instruments for measuring student perceptions of what …

Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith Jul 2020

Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith

Dissertations and Theses

There have been multiple national calls for curricular reform in college-level science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" which include skills in: communication, collaboration, and application. We developed and implemented a deliberative pedagogy, Deliberative Democracy (DD), across introductory majors and non-majors biology courses and a majors chemistry course. In two separate studies, I took a longitudinal, qualitative research approach to understand introductory biology and chemistry students' experiences and perceptions of DD. For the first study, I tracked a cohort …

Exploring User Interface Improvements For Software Developers Who Are Blind, Guarionex J. Salivia, Flint D. Million, Megan E. Bening Jul 2020

Exploring User Interface Improvements For Software Developers Who Are Blind, Guarionex J. Salivia, Flint D. Million, Megan E. Bening

Journal of Science Education for Students with Disabilities

Software developers who are blind and interact with the computer non-visually face unique challenges with information retrieval. We explore the use of speech and Braille combined with software to provide an improved interface to aid with challenges associated with information retrieval. We motivate our design on common tasks performed by students in a software development course using a Microprocessor without Interlocked Pipeline Stages (MIPS) architecture simulation tool. We test our interface via a single-subject longitudinal study, and we measure and show improvement in both the user’s performance and the user experience.

Astrodance: Engaging Deaf And Hard-Of-Hearing Students In Astrophysics Via Multimedia Performances, Jason Nordhaus, Manuela Campanelli, Joe Bochner, Thomas Warfield, Hans-Peter Bischof, Jake Noel-Storr

Journal of Science Education for Students with Disabilities

The dynamics of gravitating astrophysical systems such as black holes and neutron stars are fascinatingly complex, offer some of nature's most spectacular phenomena, and capture the public's imagination in ways that few subjects can. Here, we describe AstroDance, a multi-media project to engage deaf and hard-of-hearing (DHH) students in astronomy and gravitational physics. AstroDance incorporates multiple means of representation of scientific concepts and was performed primarily for secondary and post-secondary audiences at ~20 venues in the northeastern US prior to the historic first detection of gravitational waves. As part of the AstroDance project, we surveyed ~1000 audience members roughly split …

Effect Of Hypothesis Type On Scientific Literacy In Nonscience Majors, Sharon Schmidt, Leanne Davis, Danyelle N. Dehner-Aganovic, Margaret (Meg) Smith Jul 2020

Effect Of Hypothesis Type On Scientific Literacy In Nonscience Majors, Sharon Schmidt, Leanne Davis, Danyelle N. Dehner-Aganovic, Margaret (Meg) Smith

Georgia Journal of Science

The University System of Georgia has undergone nine consolidations of institutions of higher education in the past seven years. One consequence of a consolidation is that faculty from historically different institutions are brought together to work in newly-created units, and this requires merging of ideas, particularly at the departmental level. In the Department of Biology of our own institution, this manifested as differences in the types of hypotheses taught in nonmajors classes in which scientific literacy is a learning outcome of high priority. Data can be useful for resolving such differences, but there was limited data on the effect of …

Using Primary Literature On Sars‐Cov‐2 To Promote Student Learning About Evolution, Jeremy L. Hsu Jul 2020

Using Primary Literature On Sars‐Cov‐2 To Promote Student Learning About Evolution, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The ongoing COVID‐19 pandemic caused by SARS‐CoV‐2 has caused widespread deaths, illnesses, and societal disruption. I describe here how I pivoted a discussion‐based senior biology capstone course to include a multiweek module surrounding one primary literature paper on the evolution of SARS‐CoV‐2 and the subsequent scientific discourse about the paper. Using a gradual reveal of the paper following the CREATE method (consider, read, elucidate, and think of the next experiment), I challenged students to learn new evolutionary principles and critically analyze the data surrounding the evolution and transmission of SARS‐CoV‐2 presented in the paper. I also provide general advice for …

Learning To Fail? Student Experiences In Remedial Mathematics In Community Colleges, Margaret P. Fay Jun 2020

Learning To Fail? Student Experiences In Remedial Mathematics In Community Colleges, Margaret P. Fay

Dissertations, Theses, and Capstone Projects

Referral to remedial coursework in mathematics is a significant barrier to degree attainment for community college students, which in turn has serious consequences for their employment and earning prospects. Students are placed into remediation when they are deemed unprepared to engage in college-level coursework, most often based on a score on a placement test. Nationally, 59% of community college students are placed into remedial math courses. Of these, only 49% complete remediation and gain access to college-level coursework. Because a college-level math course is often a degree requirement, many students who fail to complete remedial math courses are forced to …

A Comparison Of Students’ Quantitative Reasoning Skills In Stem And Non-Stem Math Pathways, Emily Elrod, Joo Young Park May 2020

A Comparison Of Students’ Quantitative Reasoning Skills In Stem And Non-Stem Math Pathways, Emily Elrod, Joo Young Park

Numeracy

Quantitative Reasoning (QR) is essential for today’s students, yet most higher education institutions have not effectively addressed this issue. This study investigates students’ quantitative reasoning in STEM and Non-STEM math pathways using a non-proprietary, NSF grant-funded instrument, the Quantitative Literacy & Reasoning Assessment (QLRA). Participants were students enrolled in at least one college-level math pathway course at a large public institution in the southeastern US. The results showed a significant difference between STEM and Non-STEM students’ QLRA scores, with STEM students (n = 244, M = 27%, SD = 16.21%) scoring, on average, about 6% higher than Non-STEM students …

Exploring Stem Kit Diagrams For Braille Readers In Inclusive Classrooms, Sariat A. Adelakun Dr May 2020

Exploring Stem Kit Diagrams For Braille Readers In Inclusive Classrooms, Sariat A. Adelakun Dr

Journal of Science Education for Students with Disabilities

Diagrams appears in many school subjects but more prominent in science and mathematics taught in schools. Accessing these diagrams in an inclusive classroom has been identified to be problematic for blind students partly due to the teaching resources available and personnel type, support and sufficiency. Diagrams are mostly omitted by teachers leaving the blind person out in such classroom to access portion of education received by their peers. In many instances, questions with diagrams are treated as bonus for blind students in some countries which is not fair to them. This study explored the efficacy of STEM Kit diagrams on …
