Instructional Decision-Making For Students In Community-Based Transition Programs, Rachel Knoepfle

University of the Pacific Theses and Dissertations

Per the Individuals with Disabilities Education Improvement Act (IDEA), students with moderate to severe intellectual disabilities are eligible to receive transition services beyond twelfth grade, if they have not met the requirements for a high school diploma. There is not a formal model for how transition services should be implemented and there a number of factors in play when considering instruction for students in transition classrooms. Thus, the following questions arise: what does teaching and learning look like in such a classroom? How do teachers of CBT programs explain and understand their curriculum decision-making processes?

This study employed the methods …

Pandemic & Education: A Conversation Between Teacher Candidates, Jake Carlsen, Eric Jensen, Anna Krytenberg

Northwest Journal of Teacher Education

When Oregon public schools closed in March 2020 due to COVID-19, Jake, Eric, and Anna were headed into the full-time student teaching segment of their year-long teacher preparation practicum experience. While everyone has faced uncertainty during the pandemic, these beginning teachers also shared unique challenges. In April they came together for a conversation with a NWJTE editor to talk about their experiences, the obstacles and opportunities facing schools right now, and their hopes for their students and themselves. All three envision a 2020-2021 school year focused on equity, inclusivity, and the importance of access for all children.

A Study On Teacher Candidates’ Questioning Strategies For English Learners Through An Interactive Classroom Simulation, Alex P. Davies Ph.D., Donita Grissom Ph.D., Michele Regalla Ph.D.

Northwest Journal of Teacher Education

This study examines a classroom simulation workshop designed for teacher candidates (TCs) to practice questioning strategies with English learners (ELs) at various English proficiency levels, through the lens of sociocultural theory. Data was collected from an assignment in an ESOL methods course consisting of questions that TCs prepared before the simulation, revised after the simulation, and responses to an open-ended questionnaire. Findings show that TCs made their questions comprehensible for beginner level ELs, however, overextended their question modification to both the intermediate and advanced levels. Implications highlight the importance of practicing questioning strategies that are appropriate for all proficiency levels.

Transformative Interviewing And The Experiences Of Multilingual Learners Not Labeled “Ell” In Us Schools, Theresa Catalano, Lydiah Kananu Kiramba, Kara Mitchell Viesca

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Recent research has documented the ways that schools adapt to increasingly multilingual and multicultural student bodies. This qualitative study explores the schooling experiences of nine K-12 multilinguals not identified as English language learners in US schools. Using “deep interviewing” strategies, the authors expose the racializing function of language, but also semiotic processes such as markedness, iconicity, and erasure and sociological concepts such as habitus that are revealed through analysis of the participants’ discourse about language and schooling. Additionally, the authors illustrate how transformative interviewing practices can spur development of learners’ own agency in creating more equitable learning contexts for themselves.

Community Teaching Experience: A Description Of The Development And Design Of A Unique Teaching Experience For Occupational Therapy Doctoral Students, Laura E. Landon, Christine Berg, Sara S. Ulfers

Journal of Occupational Therapy Education

Entry-level occupational therapy doctorate (OTD) students receive education and training to interpret and disseminate evidenced-based literature. However, these students are often missing the clinical experience to identify clinically relevant questions that impact occupational outcomes. Conversely, occupational therapy practitioners have the clinical experience to determine clinically appropriate questions but often encounter time, budget, and setting constraints on researching and learning up-to-date evidence-based practice assessment and intervention techniques. The purpose of this paper is to describe the development and design of an exploratory educational project in which OTD students utilized clinically relevant questions identified by local occupational therapy practitioners to disseminate evidence-based …

Exploring Aspects Of Science Literacy Demonstrated By Early Undergraduate Stem Majors Through A Manuscript-Style Writing Assignment, Samantha Lynn Jusino

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over the past twenty years, scientific literacy amongst undergraduates has not improved despite their exposure to higher education science classes. Underlying mechanisms of science literacy development are poorly understood; however, exposure to authentic practices in science has been demonstrated as a means to fostering science literacy development. A unique approach to studying science literacy is through examining the three domains of the science literacy conceptual framework developed in this study, Science as Access, Science as Process, and Science as a Sociopolitical Factor and their components as they emerge through the process of writing a manuscript-style writing assignment. In …

“I Don't Really Look Very Asian”: Transracially And Transnationally Adopted Asian Youth In Rural Appalachia, Sandra L. Rodeheaver

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transracially adopted Asian children in rural Appalachia find themselves adopted into places where there is little or no racial and ethnic diversity. In this context, it may be difficult to transgress the model minority stereotype and systemic racism in schools and the community. There are particular issues and concerns related to racial identity for TRAAs that may make the task of becoming fully integrated members of the community challenging. Building on the literature on transracial and transnational adoption, this study aims to better understand the lives and perspectives of two transracially adopted Asian (TRAA) girls living in rural Appalachia and …

The Effects Of Instructor Self-Disclosure On Students’ Cognitive Learning: A Live Lecture Experiment, Stephen Michael Kromka

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to examine the causal influences of relevant (and irrelevant) instructor self-disclosure on student affect and cognitive learning. Relevant self-disclosure involves the instructor directly relating personal disclosures to important lesson content, whereas irrelevant self-disclosure involves the instructor’s personal disclosures straying from the lesson topic. Given previous correlational self-disclosure research, the researcher predicted that relevant (compared to irrelevant) instructor self-disclosure would lead to increased reports of affect toward the instructor. The researcher also predicted that instructor self-disclosure relevance (compared to irrelevance) would enhance lesson coherence, and in turn, foster students’ cognitive learning. The researcher conducted a …

Instructional Design Leadership And Management Competencies: Job Description Analysis, Joel Gardner, Lewis Chongwony, Amie Tope

All Faculty and Staff Scholarship

Researchers in the field of instructional design and educational technology journals usually focus on the practice of instructional design; however, the management and leadership of instructional design has typically received little emphasis. Recent studies have investigated the competencies associated with effective leadership and management of instructional design from the perspective of those they lead, and from the perspective of leaders in higher education. There is, however, little systematic research into what competencies employers require of leaders and managers of instructional designers in higher education. This research would provide the field with further guidance on training and preparing instructional design leaders …

Factors Predictive Of Self-Efficacy In First Year Teachers, Jessica Leigh Hamelin

UNF Graduate Theses and Dissertations

Research demonstrates that there are increased teacher burnout rates within the first 5 years of entering the field (Darling-Hammond, 2003; Skaalvik & Skaalvik, 2010; Yost, 2006). Consistent with those findings is that teacher preparation matters when conversing about recruitment and retention (Brown, Lee, & Collins, 2014). As more research is conducted in the area of teacher preparation it has become clear that teacher effectiveness is directly related to preparation (Darling-Hammond, 2010). As teachers enter their first-year teaching, philosophical stances can change, inflated beliefs about the teaching profession can be altered, and self-efficacy is influenced. Drawing from Hoy and Spero’s (2005) …

Teacher Approaches To Women’S History, Gender, And Feminism In Secondary Social Studies, Kimberly R. Bowman

Theses and Dissertations

While several scholars have worked to reimagine social studies curriculum from a feminist perspective, there are few studies that look at how teachers understand and experience gender equity work (Bohan, 2017; Engebretson, 2018). This study seeks to bridge that gap between theory and practice in order to progress toward a more gender-equitable social studies education. Utilizing a hermeneutic circle design to facilitate dialogue across participants, I conducted one-on-one, semi-structured interviews with seven secondary social studies teacher participants and collected participant-provided curriculum materials. Using techniques from constructivist grounded theory, I analyzed how teachers made sense of their experiences trying to include …

Unpacking "Giftedness": Research And Strategies For Promoting Racial And Socioeconomic Equity, David B. Naff, Genevieve Siegel-Hawley, Amy Jefferson, Michael Schad, Morgan Saxby, Kathryn Haines, Zoey Lu

MERC Publications

Giftedness as a construct continues to be contested in academia, in the classroom and around kitchen tables. It means different things to different communities and, as a result, acquiring the "gifted" label looks different around the country. Once labeled, student giftedness produces different responses depending on state and district guidelines. A constant among the patchwork of defining, identifying and responding to student giftedness, though, is a serious racial and economic disparity in who is considered gifted and who is not. This report provides key takeaways from research literature on gifted and talented (GT) programs. It is organized according to five …
