How Much Do Emotional, Behavioral, And Cognitive Factors Actually Impact College Student Attitudes Towards English Language Learning? A Quantitative And Qualitative Study, Xin Zuo, Regina D. Weaver, Julia Macrae, Limin Wang

Intensive English Language Program Faculty Publications and Presentations

Researchers have proposed many multidimensional frameworks to identify significant and potential factors, e.g., educational background, positive feelings and career aspirations, that impact English learning attitude in second language acquisition. Yet, there is still very little research to graphically describe the interactions between these factors and how these factors directly or indirectly impact learning attitude. To this end, a questionnaire survey was conducted in Changchun University of Technology. Statistical measures and Bayesian network analysis were introduced to quantitatively and qualitatively analyze the collected data. Furthermore, the significant attitudinal differences between students majoring in the Liberal Arts or Sciences were investigated for …

The More Things Change: The Collaborative Art Library, Elsa Loftis

Library Faculty and Staff Publications and Presentations

The academic library’s art collection has a history of fluidity and flux. Teaching and learning materials that support visual art education can range from traditional formats like image collections and monographs to the curious, the rare, and sometimes the downright unusual. Art library professionals must plan for the future of the academic library collection with intention and sensitivity to the learning styles of their students while adhering to the environmental realities of their governing institutions. One constant is clear, which is that art students are not content to be mere consumers of information and images; they are creators. It is …

Investigating Metrical Context Effects On Anticipatory Coarticulation In Connected Speech Development, Jillian Adkins, Christina Gildersleeve-Neumann, Melissa A. Redford

Speech and Hearing Sciences Faculty Publications and Presentations

If rhythm acquisition is influenced by the development of articulatory timing, then metrical structure might be expected to condition this timing. This study tested this hypothesis by investigating anticipatory effects of an upcoming noun on the production of a preceding determiner, under the assumption that anticipatory coarticulation indexes chunking. Simple S-V-O sentences were elicited from 5-year-olds, 8-year-olds, and adults. The V was either monosyllabic packed or disyllabic patted. The O was a determiner phrase where nouns varied either in onset place-of-articulation (POA; tack vs. cat) or in their rhymes (tack vs. toot). Acoustic analyses of determiner schwa F1 and F2 …

Words Matter: Putting An End To “Unsafe” And “Risky” Sex, Julia L. Marcus, Jonathan Snowden

OHSU-PSU School of Public Health Faculty Publications and Presentations

Change is constant in sexual health, as in health care more broadly. Novel pathogens are identified, epidemics emerge and reemerge, and new preventive and therapeutic agents are introduced and taken up by populations. On the other hand, some care strategies and practices fall by the wayside among clinicians and populations. Just as health and health care evolve, so too should the language that we use to describe them.

In this commentary, we express our concerns about the use of ambiguous and stigmatizing language when describing sexual behavior. A search on PubMed in September 2019 yielded over four thousand articles with …

The Relationship Between A University-Based Mentorship Program And First-Year Teachers’ Performance, Alicia C. Stapp, Laura F. Prior, Catherine Harmon

Northwest Journal of Teacher Education

Teacher attrition affects both the stability and quality of schools. Nearly 24% of teachers leave after one year, 33% leave after three years, and 40-50% leave within their first five years (Geiger & Pivovarova, 2018). Effective mentorship programs can effectively assist teachers in overcoming the challenges that lead to resignation. This study implemented a teacher mentorship program where the mentor was a teacher educator who had worked with the mentees in their undergraduate program. Utilizing a qualitative approach, the study examined first-year teachers’ performance through monthly field observations, interviews, and self-reflections. Themes emerged that are critical to a first-year teacher’s …

Evaluation Of Shared Space To Reduce Traffic Congestion, Kimley Frosch, David Martinelli, Avinash Unnikrishnan

Civil and Environmental Engineering Faculty Publications and Presentations

Pedestrian and vehicle interactions often lead to conflicts that bring about safety, traffic congestion, and priority or right of way issues. Common methods used in the past to combat said issues have largely relied on the principle of separating the motions of pedestrians and vehicles by means of bridges, tunnels, signals, and access restrictions. A different approach known as shared space aims to solve the same problems with a less structured and defined environment which instead places more reliance on human interaction and perception. Although it has been used in multiple scenarios across Europe with success, instances of shared spaces …

Pre-Service Educators' Understanding And Perceptions Of Asd Before And After Reading Asd Narrative Fiction, Brenda L. Barrio, Jane E. Kelley, Teresa Cardon

Northwest Journal of Teacher Education

Pre-service teachers and other educators are expected to understand and teach students from diverse backgrounds and varying abilities. One group that is growing in all classrooms across the U.S. are students with autism spectrum disorder (ASD). As such, it is essential that teacher preparation programs prepare pre-service teachers and educators to teach students with ASD. The purpose of the research was to examine the effects of pre-service teachers understanding and perceptions about ASD before and after reading young adult literature about characters with ASD. Results of parallel mixed-method research showed an increase of positive attitudes of pre-service teachers and educators' …

We Would If We Could: Examining Culturally Responsive Teaching Self-Efficacy In A Middle School Mathematics Methods Course, Jamaal R. Young, Jemimah L. Young, Brandon L. Fox, Earl R. Levingston Jr., Alana Tholen

Northwest Journal of Teacher Education

Despite mounting evidence of the pedagogical importance of culturally responsive teaching, many teachers do not implement culturally responsive practices in their classrooms. The purpose of this study was to investigate pre-service mathematics teachers’ culturally responsive teaching and outcome expectancy in order to inform teacher preparation in mathematics methods courses. Participants completed the Culturally Responsive Teaching Self-efficacy Scale (CRTSE) and the Culturally Response Teaching Outcome Expectancy (CRTOE) Scale. Results suggest that middle school mathematics teachers were only moderately efficacious in their ability to implement culturally responsive teaching practices, despite strong beliefs in the instructional utility of culturally responsive teaching practices.

Administrators' Insights Into The Preparation And Performance Of New Teachers, Sarah J. Kaka, Jennifer A. Tygret

Northwest Journal of Teacher Education

There are few studies that focus on the perceptions and experiences of school administrators toward new teachers; however, understanding of both are required for accreditation. Furthermore, the school administrators’ perceptions of the training, as well as teachers’ performance and impact on student learning during their first years of teaching is vital to determine how new teachers are performing in the classroom. This case study explored these perceptions and three main themes emerged: Indicators of New Teacher Effectiveness, Evidence of Impact on Student Learning, and Identified Areas for Growth. Insight for understanding ways to improve teacher preparation are included.

Perceptions Of Teacher-Writers: Initial Influences To Write, Shari L. Daniels, Pamela Beck

Northwest Journal of Teacher Education

This qualitative case study explores perceptions of teacher-writers’ early writing histories and examines their initial influences to write. Interviews and writing artifacts of ten K-12 teacher-writers serve as the primary data source. Findings indicate that teachers with strong identities as readers and/or writers in their K-12 experiences often received positive feedback which encouraged them to develop as writers, while teachers challenged with mechanics often received negative feedback which discouraged them from writing. Revisiting negative writing histories reshaped writing beliefs to influence a positive writing identities. The authors suggest practices for pre-service literacy courses to examine writing histories and to develop …

"We Were At Our Journey's End" : Settler Sovereignty Formation In Oregon, Katrine Barber

History Faculty Publications and Presentations

For too long, Oregon history has been captive to the mid-nineteenth-century’s rambling wagon trains. Settler stories of motivations, hardships, and achievements, preserved in diaries, letters, and memoirs, are compelling and deserving of the attention lavished on them. But more is necessary. Oregon’s Euro-Americans were intimately tied to national and international events that saw the rise of White, European colonial expansion into the colored word. Alongside that expansion was the development of a framework of domination, justified by claims of superiority and destiny, that conflated the ability to control with the right to do so. Placing Oregon history in this larger …

Using Virtual Reality And Web Conferencing Technologies: Exploring Alternatives For Microteaching In A Rural Region, Raymond A. Dixon, Cassidy Hall, Farjahan Shawon

Northwest Journal of Teacher Education

Preservice teachers’ views of two types of technologies which provided realistic environments in which to practice microteaching are described: (1) TLE TeachLivE™ Lab, a virtual reality environment that employs avatars as students in a virtual classroom, and (2) web conferencing technology to synchronously teach students in remotely located classrooms. Preservice teachers opined that each technology offers a relatively realistic environment that allows them to interact with virtual and real students. Microteaching through these technologies increases their self-confidence and provided a safe, non-threatening environment for them to reflect on their practice. We concluded these emerging technologies can provide viable alternatives to …

Illuminating Social Justice In The Framework: Transformative Methodology, Concept Mapping And Learning Outcomes Development For Critical Information Literacy, Nicole A. Branch

Communications in Information Literacy

The intentional omission of learning outcomes from the ACRL Framework for Information Literacy in Higher Education has caused concern and criticism from some librarians; however, the call to action within the Framework to locally develop learning outcomes is an opportunity to illuminate the social justice, critical thinking, and higher order thinking elements of information literacy.
