Opportunity To Learn Informational Text And Literary Text And Their Relations With Student Reading Achievement: An Examination With The Pirls 2011 And The Naep 2011 Reading Assessments, Dan Li Jan 2018

Opportunity To Learn Informational Text And Literary Text And Their Relations With Student Reading Achievement: An Examination With The Pirls 2011 And The Naep 2011 Reading Assessments, Dan Li

Graduate Theses and Dissertations

Several national and international studies have indicated that there is an achievement gap between student literary reading and student informational reading, with the gap favoring literary reading. One plausible explanation for this gap is that reading informational text has been neglected in early grades in the U.S. (Dreher, 2003; Kletzien & Dreher, 2004; Moss, 2008; Moss & Newton, 2002). Even more concerning, students from low-SES families seem to be struggling more with informational text than their affluent peers, since children in low-SES schools are historically reported to have fewer opportunities to develop their informational text reading skills compared to students in affluent schools (Duke, 2000b). In recent years, with the implementation of Common Core State Standards, more emphasis has been placed on students’ ability to comprehend and write informational text. However research gaps exist in the domain of opportunity to learn informational text and literary text in schools with different SES.

The purpose of this study is to bridge these research gap by fulfilling three primary goals: 1) examine students’ opportunity to learn (content exposure and content emphasis of) informational text relative to their opportunity to learn (content exposure and content emphasis of) literary text; 2) investigate if there is inequity between low- and high- SES schools with regards to students’ opportunity to learn informational text; 3) explore the relationship between SES, opportunity to learn (content exposure and content emphasis), and student reading performance. Descriptive statistics, paired-sample t-tests, latent profile analysis ...


Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas Jan 2018

Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas

Graduate Theses and Dissertations

Effective early science learning opportunities are critical for young children to build a solid foundation for subsequent development of concepts, as well as positive attitudes towards science (Eshach & Fried, 2005). However, these opportunities are often lacking in typical preschool classrooms (Connor, Morrison, & Slominski, 2006; Early et al., 2010). A multiple case study design was used to examine science learning opportunities in preschool classrooms using the Project Approach (PA; Helm & Katz, 2011). Guided by theoretical tenets from Dewey, Piaget, and Vygotsky, this study sought to explore the feasibility and efficacy of using the PA to promote high-quality science learning opportunities by examining the specific strategies teachers used to plan for authentic and meaningful experiences, structure the environment ...

Who I Want You To Be: Three Portraits Of Culturally Competent Teachers Improving The Mental Health Of Students, Jennifer L. Wells Jan 2018

Who I Want You To Be: Three Portraits Of Culturally Competent Teachers Improving The Mental Health Of Students, Jennifer L. Wells

Graduate Theses and Dissertations

There is a lack of critical research addressing racism as a dynamic of mental health in schools. In the critical view, US schools mirror a social system built on an ideology of white supremacy; the US school system may perpetuate racial trauma for students of color. Teachers who demonstrate culturally competent identities in practice have important roles to play in counteracting racial trauma and promoting the mental health of students of color.

This qualitative study explores how culturally competent teachers make sense of their identities, how they make sense of their students’ identities to build relationships, and how they understand ...

Undergraduate Research Training Environments: Impact On Research Self-Efficacy, Perceived Utility Of Research, And Willingness To Engage In Research Post-Graduation, Kaitlyn Burke

Graduate Theses and Dissertations

Effective research training environments (RTEs) within graduate psychology degree

programs have been shown to increase students' level of research self-efficacy (RSE). Higher

levels of student RSE are likely associated with the greater perceptions of the utility of research

skills and a greater willingness to engage in research-based activities in later professional work.

Relations among the variables of RTEs, RSE, and continuing research-based activities have been

well established among graduate psychology students, but the effect of RTEs in undergraduate

psychology training has not yet been examined. The focus of students’ perceived utility of their

research skills post-graduation was a new addition ...

La Trenza De Las Fronterizas: The Cultural Worlds First-Generation Women Navigate To Access College, Katherine Cameron Seifert

Graduate Theses and Dissertations

First generation female students of color face challenges in accessing and navigating the college-going realm. Scholars write about this population, but their tone is often deficit-based, focusing on these students’, families’, and communities’ shortcomings rather than highlighting their resilience and adept abilities at transitioning between different cultural worlds. Using Holland’s (1998) theory of cultural worlds, and employing portraiture methodology, tools of feminist research, and narrative ethnography, this intimate micro-study examines the college-going world that young women of minoritized identities navigates. It asks: (a) What are the identities, relationships, and resources that construe their participation in this world? (b) What ...

A Mixed-Methods Longitudinal Study Of New Graduate Teaching Assistants’ Commenting Beliefs And Practices, Jillian I. B. Grauman Jan 2018

A Mixed-Methods Longitudinal Study Of New Graduate Teaching Assistants’ Commenting Beliefs And Practices, Jillian I. B. Grauman

Graduate Theses and Dissertations

Although research on teachers’ comments on student papers is fairly common and has remained an ongoing area of interest since at least the 1970s, composition studies has not yet investigated how teachers’ commenting beliefs and practices change over time, particularly graduate teaching assistants’ (GTAs’) commenting practices. GTAs are an important subgroup of composition instructors to study because not only do they teach a considerable number of first-year composition (FYC) classes across the country, they are also the future of the profession. This dissertation reports the results of a mixed-methods longitudinal study of novice GTAs’ commenting beliefs (i.e., goals, perceived ...


The Systematic Subjugation Of Women And The Environment In The Hunger Games And The Windup Girl, Rachel Grotzke Jan 2018

The Systematic Subjugation Of Women And The Environment In The Hunger Games And The Windup Girl, Rachel Grotzke

Graduate Theses and Dissertations

This analysis focuses on the system of subjugation present in the 21st century dystopian narratives The Hunger Games and The Windup Girl to show the dual entrapment of women and nature. The first step of the system of subjugation, lack of resources, manifests in both of the texts and points to the environmental justice underpinnings of the texts. Through close analysis of the type and breadth of the environmental injustices suffered, this lack of resources leads to the second step in the system of subjugation: objectification. Because of the need of resources those in power exploit, women are then seen ...

Teaching Structural Analysis With A Mobile Augmented Reality Application, Suhan Yao Jan 2018

Teaching Structural Analysis With A Mobile Augmented Reality Application, Suhan Yao

Graduate Theses and Dissertations

Structural analysis is a core course taught in every undergraduate civil engineering program and most architectural and construction engineering programs. Despite the critical role of this subject matter in engineering education, students usually have difficulty in grasping the abstract concepts, visualizing the deformed shape of simple structures, and relating basic structural members to more complex structural systems such as buildings and bridges. To help students to visualize the structural behaviors as well as linking structural representations with physical structures, a mobile augmented reality (AR) application, iStructAR, was developed. Through the application, a real campus building is superimposed with a virtual ...


Training Reduces The Drawing Detriments Associated With Categorical Perception, Larissa F. Arnold Jan 2018

Training Reduces The Drawing Detriments Associated With Categorical Perception, Larissa F. Arnold

Graduate Theses and Dissertations

Previous research suggests that categorical perception may interfere with a novice artist’s ability to accurately draw simple shapes. Specifically, when asked to draw two shapes of slightly different sizes, participants tend to exaggerate the categorical difference between the two and draw the small shape too small. Similarly, participants tend to draw oblique angles more oblique than they should be when they are close to perpendicular or overlapping. The current set of experiments investigated whether these categorical errors could predict participants’ drawing ability on a more complex drawing task. A simple linear regression revealed that categorical errors in angle could ...
