LEADERSHIP ACTIONS FOR TECHNOLOGY INTEGRATION INTO SCHOOLS

Thesis (Ed.D.) - Indiana University, Department of Educational Leadership and Policy Studies/School of Education, 2025This dissertation presents findings from a single case study in one elementary school. As technology integration in schools continues to develop, this study looks at the role of a school principal as she engages in technology leadership. The study is designed around a conceptual framework by Scott McLeod (2015) who defines leadership actions that are central to integrating technology in schools undergoing improvement as the following: setting forth a unified vision with the purpose for the initiative; eliminating the fear of change in community and staff members; releasing control to allow students more autonomy; and supporting parents, teachers, and students with professional learning and a robust infrastructure. Data collection included interviews, observations, and professional documents and artifacts. There are two key findings for school leaders working to integrate technology: principals must operationalize a vision by creating conditions for teacher learning and principals must provide access and build capacity

HOW ASYNCHRONOUS ONLINE BEGINNING SPANISH STUDENTS USE ORAL COMMUNICATION: A DESCRIPTIVE CASE STUDY

Thesis (Ed.D.) - Indiana University, Department of Curriculum and Instruction/School of Education, 2025Communicative language teaching places an emphasis on oral language usage within the L2 classroom, yet although asynchronous online courses can incorporate multimedia, they often rely on written communication. Because there are online asynchronous language courses, and there is a juxtaposition between the communicative language practices and online course delivery, this qualitative descriptive case study explored the main question: How do beginning students use target language oral communication in an asynchronous online beginning Spanish course at a community college? The two subquestions guiding the study were: (a) What are the factors that mediate students’ oral engagement in an asynchronous online beginning Spanish course at a community college? and (b) What are the ways that students demonstrate interpersonal and presentational oral communication in an asynchronous online beginning Spanish course at a community college? This study adopted a qualitative descriptive case study approach and used activity theory and ACTFL guidelines frameworks to frame the study of a 1st semester asynchronous online beginning Spanish course. Content analysis was used to analyze the oral communication assignments of 11 student participants, interviews with 5 focal student participants, and course materials and documents. The findings illuminated the variety of artifacts (tools and signs), their roles, and the role of community in mediating oral communication. Additionally, the findings showed that technology as well as norms can hinder oral communication. The findings also demonstrated types of interpersonal and presentational language that learners produced. Based on the findings, this study highlighted how students learn target language oral communication in an asynchronous online environment. The findings suggest the usage of a variety of artifacts and social interaction with community are important considerations for course design and asynchronous teaching practices. Furthermore, the findings suggest that counter to the belief that teaching oral language mastery is not achievable in online courses, beginning language students in a completely asynchronous online course are capable of producing L2 interpersonal and presentational oral language in alignment with ACTFL novice level proficiency Can-Do statements

New Depths: Furthering Innovative Research Evaluation for an Evidence-Based Teen Program

The YMCA of Greater Louisville partnered with Indiana University Southeast’s Applied Research and Education Center (AREC) to develop and evaluate an innovative, evidence-based youth program. At AREC, ethnographic study conducted by a near-peer undergraduate observer and hiring a youth evaluation advisor are how we continue to use participatory, utilization-focused and action research to contextualize and better feedback for the evaluation research findings. Data collected from these grants will serve research and evaluation publications, help secure new funding, and promote sustainability of these programs through continued YMCA implementation and dissemination of the models to other youth-serving organizations

Behind the Curtain: How Library of Congress Vocabulary Terms Are Created and Maintained

Presented as part of the panel, Unveiling the Fictions, Politics, and Distortions in the Scholarly Information Ecosystem, at the 2025 annual conference of the American Folklore Society in Atlanta, Georgia.The Library of Congress (LC) maintains a set of controlled vocabulary terms that are used to describe and promote the discovery of materials through library catalogs and online databases around the world. But how are these terms added and maintained, and what determines which term is the “authorized” heading displayed to researchers and other users? Intended as an overview for non-librarians, this presentation attempts to remove the mystery surrounding these processes and discuss some of the current forces, such as critical cataloging, metadata remediation and the political climate, on LC vocabulary terms

Power Analyses Power Hour: Understanding and Conducting Statistical Power For Your Research

Elizabeth Ray is a Social Psychology PhD Candidate from the PBS Department working with Advisor, Dr. Ed Hirt. She joined the Indiana Statistical Consulting Center as a Consultant in the spring of 2023. She earned her MS in Psychology in 2022 as well as a BS in Psychology, Philosophy, and Sociology with concentrations in social research and ethics at the University of Indianapolis. Neela Klein is a Social Psychology PhD Candidate from the PBS Department working with Advisor, Dr. Kurt Hugenberg. As a consultant at the Indiana Statistical Consulting Center with an MS in Experimental Psychology from William & Mary, and a BA in Psychology from University of Richmond, Neela specializes in experimental and survey design, as well as race and gender research.From research design, to grant proposals, preregistrations, post hoc results interpretation, journal submissions, and beyond, power analysis is an important part of the scientific process. A priori power analysis determines the sufficient sample size needed to reach desired power and effect size without wasting resources through overpowering a study and without underpowering a study or analysis. The goal of this workshop is to provide IU faculty, staff, and graduate students an accessible, conceptual, and practical understanding of statistical power, effect size, writing power analysis results, and using G*Power software. The workshop will cover power analysis related definitions, theoretical concepts such as the importance of power analysis, point and click examples in G*Power, resources, and more. Though not required, to make the most of your attendance, arrive with the free and open source software, G*Power, already downloaded

What is Self-Archiving (and Why You Should)

An IU Libraries blog post. "Journals come and go. Academic societies merge or fade in relevance. Projects end abruptly. Scholarly work should create a permanent record, but the reality of human and institutional lives can interfere. There’s no single solution to the tides of time, but self-archiving is one popular method for preservation...
