Arab Undergraduate Students' Perceptions Of Their Transition To Learn Mathematics In English In The United States, Annetta Hastings

USF Tampa Graduate Theses and Dissertations

The number of students who choose to pursue higher education outside their home country has continued to grow, and one of the most popular international destinations is the United States. International students, whose home language is not English, can find this educational opportunity to be academically challenging. Institutions of higher learning can admit international students and expect them to adjust to the linguistic, cultural, and social differences in a new educational system without appropriate support. To better support international students in undergraduate mathematics, researchers have focused on how language and culture affect mathematical understanding (Barton & Neville-Barton, 2003; Durand-Guerrier et …

Exploring Factors In Choosing Stem Majors And Careers: Improving Science Education Through The Lens Of Self-Determination Theory, Lauren Mott

Honors Program: Senior Projects (Public)

Several barriers currently exist for students who could be successful in science/STEM careers but have not had the support they needed throughout their science/STEM education. This study of the literature applies Self-Determination Theory (SDT) to existing research to identify steps educators can take to remove these unnecessary barriers for their students. SDT defines competence, relatedness, and autonomy as three innate psychological needs that must be met for well-being. An exploratory review of the literature was conducted, and findings were organized using SDT. The results showed that competence, relatedness, and autonomy were all key factors in students’ self-determination of science/STEM careers. …

Young Adolescents’ Opportunity To Develop Concept Images Of Polygons In Middle School Mathematics Textbooks, Megan N. Cannon

USF Tampa Graduate Theses and Dissertations

Young adolescents build notions of figures through experiences. When young adolescentsbegin middle school mathematics, they already have prior assumptions and conceptualizations about shapes (Herbst, Fujita, Halverscheid, & Weiss, 2017). Over years of experiences, interactions, and exposures with a particular concept, these students develop concept images consisting of all the visual information, pictures, mental images, or properties associated with the particular mathematical concept (Vinner, 1983). Seminal works in the field of mathematics education research found that without an opportunity to engage with varied representations, young adolescent students may not develop robust concept images (Aspinwall, Shaw & Presmeg, 1997; Hasegawa, 1997; Mesa, …

Conceptual Metaphors For Isomorphism And Homomorphism: Instructors’ Descriptions For Themselves And When Teaching, Rachel Rupnow

Faculty Articles, Papers, and Other Scholarship

Group isomorphism and homomorphism are topics central to abstract algebra, yet research on instructors’ views of these concepts is limited. Based on interviews from two instructors as well as classroom video from eight class periods, this paper examines the language used to discuss isomorphism and homomorphism. Language used by instructors in interviews and classroom settings are identified and classified into four main categories: formal definition, mapping, sameness, and combinations of sameness and mapping language. How the two instructors drew on language classified into those four categories in the interview and instruction settings are examined for isomorphism and homomorphism. Similarities and …

Modeling The Ecological Dynamics Of A Three-Species Fish Population In The Chesapeake Bay, Iordanka N. Panayotova, Maila B. Hallare

CODEE Journal

We present an inquiry-based project that is designed for a mathematical modeling class of undergraduate junior or senior students. It discusses a three-species mathematical model that simulates the biological interactions among three important fish species in the Chesapeake Bay: the prey Atlantic menhaden and its two competing predators, the striped bass and the non-native blue catfish. The model also considers the following ecological issues related to these three species: the overfishing of menhaden, the invasiveness of the blue catfish, and the harvesting of blue catfish as a method to control the population. A series of modeling scenarios are considered based …

Engaging Students Early By Internationalizing The Undergraduate Calculus Course, Chinenye Ofodile

CODEE Journal

Today's world is global. However, despite increasing numbers and diversity of participants in Study Abroad programs, only 10% of U. S. college students get that experience. There is an ever-growing need for students to become aware of and experience other cultures, to understand why others think and act differently. Internationalization is the conscious effort, begun nearly 40 years ago, to integrate an international, intercultural, and global dimension into the purpose, functions, and delivery of post-secondary education.

Albany State University began a Global Program Initiative in the 1990s. In 2016, we extended into mathematics the curriculum innovations of this program. The …

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 …

Epidemiology And The Sir Model: Historical Context To Modern Applications, Francesca Bernardi, Manuchehr Aminian

CODEE Journal

We suggest the use of historical documents and primary sources, as well as data and articles from recent events, to teach students about mathematical epidemiology. We propose a project suitable -- in different versions -- as part of a class syllabus, as an undergraduate research project, and as an extra credit assignment. Throughout this project, students explore mathematical, historical, and sociological aspects of the SIR model and approach data analysis and interpretation. Based on their work, students form opinions on public health decisions and related consequences. Feedback from students has been encouraging.

We begin our project by having students read …

Facing The Pandemic Together: Forming A Collaborative Research Group, Michael C. Barg

CODEE Journal

This is an account of how a reading and writing project in an introductory differential equations course was transitioned to a professor-student research group collaborative project, in response to the global COVID-19 pandemic. Adapting on the fly to the ever-evolving pandemic, we collected data, estimated parameters in our models, and computed numerical solutions to SIR-based systems of differential equations. This is a description of what we did and how we found comfort in the project in this time of great uncertainty. The collaboration yielded successes and more questions than we had answers for, but the situation provided an opportunity of …

A balanced approach to integrated STEAM education uses real issues from around the world to challenge students to be innovative, creative, and think critically about ways they can provide solutions. The purpose of this article is to highlight the potential of a transdisciplinary STEAM instructional approach, while examining the barriers that teachers face in …

Preservice Science And Mathematics Teachers’ Acculturation Into Communities Of Practice: A Call For Undergraduate Research In Science And Mathematics Teacher Preparation, Kara Esther Baldwin, Rebekka Darner

Journal of STEM Teacher Education

Current mathematics and science standards, namely the Common Core State Standards of Mathematics (CCSSM) and the Next Generation Science Standards (NGSS), emphasize engaging students in mathematical and scientific practices. This review article is driven by the question: How can we expect science and mathematics teachers to appropriately engage students in the practices of the scientific and mathematical disciplines, when most teachers themselves lack experience practicing as scientists and mathematicians? To address this question, we review the literature on teachers’ understanding of their discipline’s practices, disciplinary practices as means to engage in inquiry, and how preservice teacher engagement in undergraduate research …

What Stem Teachers Need To Know And Do To Engage Families Of Emergent Multilingual Students (English Language Learners), Lisa Hoffman, Emily Suh, Alan Zollman

Journal of STEM Teacher Education

STEM teacher educators are aware that we teach far more than content-specific methodology. Educators need to guide STEM teachers in the knowledge and skills to support emergent multilingual students (English language learners, or ELLs) by simultaneously developing their STEM content learning and scaffolding their language acquisition (Hoffman & Zollman, 2016; Suh, Hoffman, & Zollman, 2020). Research identifies the family unit having a profound effect upon student learning and educational choices. Educators, educational researchers, and policymakers alike recognize the importance of family involvement in education (Grant & Ray, 2019). Although previous family engagement initiatives have focused on teaching families from a …

Airbags As Real-Life Applications For Science, Carly A. Rock, Brooke A. Whitworth

Publications

At the core of an effective model-based inquiry (MBI) unit is a scientifically rich, complex phenomenon that serves as the reason for engagement and drives student sensemaking and investigations throughout the unit. Engaging in iterative attempts to explain phenomena over the course of an MBI unit allows the opportunity for students to construct evidence-based explanations that are refined over time with various science practices. We provide an example of using MBI as an instructional model to facilitate students’ conceptual understanding of chemical reactions.

Word-Problem-Solving Interventions For Elementary Students With Learning Disabilities: A Selective Meta-Analysis Of The Literature, Jennifer E. Kong, Christy Yan, Allison Serceki, H. Lee Swanson

Education Faculty Articles and Research

This meta-analysis assessed the effect of word-problem-solving interventions on the word-problem-solving accuracy of students identified as having a learning disability (LD) or at risk for an LD in kindergarten to the sixth grade. Eighteen randomized control group designed studies met the inclusion criteria. Overall, word-problem-solving interventions yielded a significant positive effect on the word-problem-solving accuracy of students in elementary grades with LD (effect size [ES] = 1.08). Instructional components that underlie effective studies were also identified. Results suggest that peer interaction and transfer instructions yielded large effects on treatment outcomes. Results also suggested that intensive interventions (50-min sessions, 34 total …

Problematizing Perceptions Of Stem Potential: Differences By Cognitive Disability Status In High School And Postsecondary Educational Outcomes, Dara Shifrer, Daniel Mackin Freeman

Sociology Faculty Publications and Presentations

The STEM (science, technology, engineering, and mathematics) potential of youth with cognitive disabilities is often dismissed through problematic perceptions of STEM ability as natural and of youth with cognitive disabilities as unable. National data on more than 15,000 adolescents from the High School Longitudinal Study of 2009 first suggest that, among youth with disabilities, youth with medicated attention-deficit/hyperactivity disorder (ADHD) have the highest levels of STEM achievement, and youth with learning or intellectual disabilities typically have the lowest. Undergraduates with medicated ADHD or autism appear to be more likely to major in STEM than youth without cognitive disabilities, and youth …

The COVID-19 pandemic has caused an abrupt shift in biology courses, with many transitioning to online instruction. This has led to an increased concern about academic integrity and cheating in online courses. Here, I draw upon the peer-reviewed literature to provide evidence-based answers to four questions concerning cheating and online biology courses: (i) What types of cheating are prevalent with the shift to online instruction? (ii) Should instructors make assessments open book and open notes? (iii) How does cheating occur in biology lab courses? (iv) Finally, what strategies can biology instructors take to uphold academic integrity with online learning? I …

Developing Students’ Curiosity Through Chemistry Hands-On Activities: A Case Of Selected Community Secondary Schools In Dar Es Salaam, Tanzania, Esther Kibga, Emmanuel Gakuba, John Sentongo

Institute for Educational Development, East Africa

Curiosity is the inner drive for learning or ‘hunger for learning’ which is among the twenty-firstcentury learning competencies. Students in their earliest stage ought to exhibit curiosity to stirup knowledge acquisition and exploration, yet the development of curiosity in the context of education is considered to be unusual. This research assesses how chemistry students develop and express curiosity in a hands-on learning environment. A sample of 169 senior three students from three community secondary schools in Dar es Salaam was involved in this study. Besides, the study examined how hands-on activities in chemistry lessons can be incorporated as a pedagogical …
