Building Postsecondary Pathways For Latinx Students In Computing: Lessons From Hispanic-Serving Institutions, Anne-Marie Núñez, David S. Knight, Sanga Kim

Departmental Technical Reports (CS)

While the COVID-19 pandemic has transformed the use of technology in education and the workforce, a shortage of computer scientists continues, and computing remains one of the least diverse STEM disciplines. Efforts to diversify the computing industry often focus on the most selective postsecondary institutions, which are predominantly White. We highlight the role of Hispanic-Serving Institutions (HSI) in gradating large numbers of STEM graduates of color, particularly Latinx students. HSIs are uniquely positioned to leverage asset-based approaches that value students’ cultural background. We describe the practices educators use in the Computing Alliance for Hispanic-Serving Institutions, a network of 40 HSIs …

Students Who Took The Class Help Studenrs Who Are Taking It: What Is The Best Arrangement?, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

The more help students get, the better. It is therefore reasonable to ask students who took the class to help students who are currently taking this class. This arrangement also help the helpers: it is known that the best way to learn the material is to teach it. An important question is: how to pair the students to get the maximal effect? In this paper, we show that, under reasonable conditions, the best effect is when we match the best performing "older" student with the worst performing "younger" one, the second best with the second worst, etc.

Just-In-Time Teaching Adds Motivation But Is Less Efficient, Vladik Kreinovich, Olga Kosheleva, Christian Servin

Departmental Technical Reports (CS)

For each major, in addition to directly major-related topics, students also need to learn auxiliary topics –- e.g., math topics –- which are needed to understand more direct major-related ones. To learn these auxiliary topics, students are required to take some prerequisite math class. The problem is that when the students take these classes, they do not fully understand how these classes are related to their major. As a result, they often lack motivations, do not study well, and this hinders their performance in the follow-up major-related classes. One way to enhance the students' motivation is to use just-in-time teaching, …

Rosenzweig, Equality, And Assignment, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In his seminal book "The Star of Redemption", the renowned philosopher Franz Rosenzweig illustrated his ideas by the intuitive difference between mathematical statements A=B and B=A. Of course, from the purely mathematical viewpoint, these two statements are always equivalent, so to a person trained in mathematics -- even in simple school mathematics -- this illustration is puzzling. What we show is that from the viewpoint of common folks, there is indeed a subtle difference between how people understand these two equalities. To us, the understanding of this difference helped us better understand Rosenzweig's ideas. But we believe that this difference …

Adversarial Teaching Approach To Cybersecurity: A Mathematical Model Explains Why It Works Well, Christian Servin, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Teaching cybersecurity means teaching all possible ways how software can be attacked -- and how to fight such attacks. From the usual pedagogical viewpoint, a natural idea seems to be to teach all these ways one by one. Surprisingly, a completely different approach works even better: when the class is divided into sparring mini-teams that try their best to attack each other and defend from each other. In spite of the lack of thoroughness, this approach generates good specialists -- but why? In this paper, by analyzing a simple mathematical model of this situation, we explain why this approach work …

How To Detect Future Einsteins: Towards Systems Approach, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Talents are rare. It is therefore important to detect and nurture future talents as early as possible. In many disciplines, this is already being done -- via gifted and talented programs, Olympiads, and other ways to select kids with unusually high achievements. However, the current approach is not perfect: some of the kids are selected simply because they are early bloomers, they do not grow into unusually successful researchers; on the other hand, many of those who later become very successful are not selected since they are late bloomers. To avoid these problems, we propose to use systems approach: to …

Advice To New Instructors: Systems Approach, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

A recent paper provided useful system-based approach to new school teachers. In this paper, we somewhat modify this advice so that it can be applied to new instructors on all levels, including new instructors at the university level.

Departmental Technical Reports (CS)

At a recent International Forum on Teacher Education (Kazan, Russia, May 27-29, 2020), special sessions were devoted to questions related to online teaching -- in view of the recent forced world-wide transition to online-only education. This article summarizes, in a systematic way, issues discussed at these sessions.

A Recent Result About Random Metrics Explains Why All Of Us Have Similar Learning Potential, Christian Servin, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In the same class, after the same lesson, the amount of learned material often differs drastically, by a factor of ten. Does this mean that people have that different learning abilities? Not really: experiments show that among different students, learning abilities differ by no more than a factor of two. This fact have been successfully used in designing innovative teaching techniques, techniques that help students realize their full learning potential. In this paper, we deal with a different question: how to explain the above experimental result. It turns out that this result about learning abilities -- which are, due to …

Secondary Student Perceptions Of School Climate Elements And Self-Reported Academic Self-Efficacy As Factors Of School Continuous Improvement, Marianne Arzadon Torales

Open Access Theses & Dissertations

State and national agencies recognize the link between school quality and student academic and behavioral outcomes. Research has shown that a positive school climate and high academic self-efficacy are associated with positive academic and behavioral student outcomes. Determining the school climate factors that contribute to academic self-efficacy will add to the limited research on the relationship between these two constructs and provide information to prospective and current school leaders in cultivating an effective school.

A multiple regression was used to determine how student-perceived school climate factors predict self-reported student academic self-efficacy and of these factors, which one provided the strongest …

Border Crossing On Sacred Grounds: An Indigenized Decolonized Educational Research Paradigm For Use In Contemporary Globalized Schooling Systems, Estella Valles

Open Access Theses & Dissertations

Presented in this work is an adapted quantitative research paradigm for use in the field of education, specifically designed for work with Indigenous/marginalized populations coined "Diachronic Research Methodology" (DRM). The model is grounded in a post-positivist, decolonization-model, that is embedded in feminist and critical race theory. DRM is presented as a counter-approach to the traditional empiricist, research methods; a process which, historically, has allowed for a limited and biased understanding of Indigenous/marginalized populations. DRM challenges Western epistemologies and worldviews which have promoted the idea of one-grand-narrative for all humans, a view argued as beyond problematic and unethical, particularly for Indigenous …

Why Immediate Repetition Is Good For Short-Time Learning Results But Bad For Long-Time Learning: Explanation Based On Decision Theory, Laxman Bokati, Julio Urenda, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

It is well known that repetition enhances learning; the question is: when is a good time for this repetition? Several experiments have shown that immediate repetition of the topic leads to better performance on the resulting test than a repetition after some time. Recent experiments showed, however, that while immediate repetition leads to better results on the test, it leads to much worse performance in the long term, i.e., several years after the material have been studied. In this paper, we use decision theory to provide a possible explanation for this unexpected phenomenon.

Morphological Production Accuracy Patterns In Younger And Older Spanish-English Bilingual Children, Isabel Angelica Cano

Open Access Theses & Dissertations

Clinicians require a model of typical bilingual language development. Morphological production accuracy patterns vary in Spanish-English (S-E) bilingual children considering differences in the exposure and use of their two languages compared to their monolingual peers. The purpose of the current study was to examine morphological production accuracy patterns in thirty younger (3- to 4-years old) and older (5- to 6-years old) S-E bilingual children utilizing English and Spanish Morphosyntax subtests from a bilingual language screener. Across development, older bilingual children were more accurate on all forms in both English and Spanish than younger bilingual children. Across languages, all S-E bilingual …

Brokering Social Capital: A Qualitative Case Study On How A Hispanic Serving Institution Fosters Social Capital For First-Generation, Latinx, On-Campus Student Employees, Christian Corrales

Open Access Theses & Dissertations

Around 80 percent of undergraduates enrolled in U.S. higher education institutions are employed (Carnevale et al., 2015; Kena, Musu-Gillette, Robinson, Wang, Rathbun, Zhang, & Velez, 2015). Research shows that student employment is one of the most critical activities that affect students' post-secondary experiences and decisions while enrolled (Pascarella & Terenzini, 2005; Perna 2010; Riggert et al., 2006; Tinto, 1993). The present study aimed at understanding how employing organizations and workplace environments of first-generation Latinx on-campus student employees influenced their ability to build social capital and navigate through higher education.

A social capital lens was used to help understand student participants' …

Open Access Theses & Dissertations

In the "age of accountability," every student counts. This includes students with disabilities. Principals play a vital role in ensuring that students with disabilities receive a high-quality education. How are university-based preparation programs preparing aspiring administrators to meet the challenges of ensuring a fair and equal education for every student, including students with disabilities? Nearly 25 years ago, a study of principal preparation programs concluded that most principals were ill prepared when they began their leadership tenure. In 2009, a study found that, although there had been an increase in the number of hours that principal preparation programs required for …

Data collected through interviews indicate that international students' struggles with digital text are much more complex than the average student because they have …

Working Memory Performance In Spanish-English Bilinguals' First And Second Languages, Jordan Allyssabeth Orozco

Open Access Theses & Dissertations

Background: Working memory is important for speech understanding in that speech recognition requires the processing, temporary storage, and manipulation of information during complex cognitive tasks. Previous research has shown contradictory findings on whether bilinguals have an advantage in working memory capacity compared to their monolingual counterparts. Differences in findings have been attributed to various factors to include task-dependent effects and poorly matched samples. Therefore, the existence of a bilingual advantage in working memory remains unclear.

Purpose: The purpose of this study was to examine the working memory performance of Spanish/English bilingual individuals compared to English monolingual individuals using a linguistically …

Familia First! A Qualitiative Study On The Impact Of Latinx First-Generation College Students' Degree Completion On Their Family In A U.S.-Mexico Border Community, Luis Jaime Mendez

Open Access Theses & Dissertations

Completing a bachelor's degree is a major milestone. The achievement can further be heightened by those who are the first in their families to graduate. By the same token, the attainment of a degree by first-generation Latinx students, who have statistically low percentages of education as compared to other ethnic groups, is crucial.

The purpose of this qualitative study was to examine the familial impact of Latinx first-generation degree completion. The primary research question directing the study was: How does degree completion impact families of Latinx first-generation college students in a U.S.-Mexico border community? Yosso's Community Cultural Wealth (CCW) model …

The Development Of A Principal's Conceptual Framework Within An Early College High School, Edmond Martinez

Open Access Theses & Dissertations

Educational leadership literature and research are dominated by linear, evidence-based methodologies to describe and guide decisions made by the school principal. These methodologies and conclusions do not examine the conceptualizations made by the principal to form the professional knowledge that makes up the framework that the principal might use to define problems, understand the problem in context and create a response. How principals form these conceptualizations by using experiences, multiple perspectives, and theories might explain how principals understand the school to address needs that are specific to the nature of the campus.

An early college high school is the setting …

Faculty Attitudes And Perspectives About Community Engaged Scholarship At An Engaged Institution, Azuri Lizeth Gonzalez

Open Access Theses & Dissertations

Community engaged scholarship has become a method for higher education institutions to respond to public and societal needs. Decades into the establishment of the "engaged institution," studies reveal that higher education presents challenges for faculty to effectively succeed in academia while pursuing a community engaged scholarship agenda. This study employs the use of a constructivist grounded theoretical approach to explore faculty attitudes and perspectives on community engaged scholarship and the role the engaged intuition may have in their views. This study found that faculty were introduced to the term by their institutions but their views and understanding of community engaged …

Mediations Of Cogenerative Dialogues Between High School Students And Scientists, Chelsea Elizabeth Lucas

Open Access Theses & Dissertations

Research shows that working with scientists is a great way to help high school students learn science more authentically. However, communication barriers might exist because of their different background. This study introduces how an exemplary mediator used cogenerative dialogues to facilitate their communications. The goal of cogenerative dialogues is to help participants communicate with respect and equity to improve collective practices. We drew on Riskin's mediation framework to analyze dialogues to illustrate the mediation styles. Results indicate that this exemplary mediator was more elicitive when discussing problems, directive when discussing solutions, and focused on broad topics of the issue that …

Caregiver Experiences With The Dyslexia Identification Process In A Borderland Community In Texas, Angela Victoria Enriqueta Owens

Open Access Theses & Dissertations

This phenomenological study (Moustakas, 1994; Peoples, 2020) uses critical disability theory (Devlin & Pothier, 2006) and intersectionality (Crenshaw, 1989) as a lens for investigating the experiences of caregivers in a borderland community in Texas during their childâ??s dyslexia identification process. I used Interpretive Phenomenological Analysis (IPA) which has roots in hermeneutic phenomenology (Heidegger, 1971) as a research method to answer the research question, how do caregivers from minoritized backgrounds in a Texas Borderland community experience the Dyslexia identification process in public schools. The three caregivers in this study were able to participate through face-to-face and virtual formats, due to the …

Language Ideologies And Identities: Beliefs And Practices Of College Level Spanish Students And An Instructor In A Spanish Heritage Language Classroom, Viridiana Vidana

Open Access Theses & Dissertations

Research on Heritage Language Learners (HLLs) began in the 1970s when the term heritage languages originated in Canada (Cummins, 2005); later in the 1990s, the subfield of heritage language education was created. HLLs are defined as “students who [are] raised in a home where a non-English language is spoken, who speak or at least understand the language, and who [are] in some degree bilingual in that language and English” (Valdés, 2001, p.38). From its inception, research on the education of HLLs has focused heavily on linguistic aspects (Beaudrie & Fairclough, 2012; Colombi & Alarcón, 1997; Potowski & Carreira, 2010), however, …

Impact Of School Closures On Principal Leadership And Identity, Isela Pena

Open Access Theses & Dissertations

This Dissertation presents findings from a phenomenological qualitative study of three principals who experienced school closures. This research aimed at exploring the impact of school closures on principal leadership and leadership identity. Utilizing the Ackerman's and Maslin-Ostrowki's (2002) concept of the wounded leader, this study framed the school closure as a critical incident which caused these principals to experience a wounding, thus providing them an opportunity to reflect and create a narrative around their experience, and through this examination, potentially undergo a transformation leading to professional and personal growth. Through semi-structured interviews, three school principals who experienced school closures, shared …

Substance Use Among 7th - 9th Grade Adolescents: The Role Of Risk- Related Variables In The Probability Of Use Involving Tobacco, Alcohol And Marijuana, Susana A. Villalobos

Open Access Theses & Dissertations

The role of schools in preventing substance use among adolescents is a priority for public health advocates across the United States. In recent years the United States has seen an increase in prescription medication overdoses in adults and adolescents. A lack of research exists of adolescents in middle school substance use (Welsh, & Rappaport, 2018). Trends of adolescent substance use of tobacco, alcohol and marijuana continue to rise. Early onset use of legal and illegal substances has proven to increase the odds of long-term use of adolescence into adulthood. Parents, educators, community advocates and law enforcement have long tackled the …

Discourses Of Coloniality In The Understanding And Practices Of Translanguaging Pedagogy, Gabriela Dolsa

Open Access Theses & Dissertations

Dual language (DL) education has been regarded as a means toward equity and social justice for linguistic minorities. Several studies, however, question if DL programs can, in fact, overcome inequities in the education of emergent bilinguals. This ethnographic study followed these inquiries and explored how translanguaging theory and pedagogy could transform DL education to better serve social justice purposes in this US-Mexico border context. For translanguaging to achieve this, it is fundamental to know how DL educators understand and practice translanguaging in their classrooms. This study revealed that teachersâ?? understandings and practices of translanguaging were embedded in ideologies of coloniality …
