Comparative Assessment Of Agricultural Literacy In Selected K-5 Classrooms Employing Agriculture In The Classroom Methodologies: A Solomon Four-Group Analysis, Mary Margaret Fischer

Dissertations

The significance of agriculture to future generations is unparalleled. The United Nations projects the global population to swell to 9.75 billion people by 2050, and to proliferate to 11.2 billion by 2100. The non-agricultural population has little to no understanding or comprehension of the complexities of sustaining a viable agricultural system. Agricultural literacy is an area often unseen and rarely discussed outside specific agricultural disciplines. Society does not view agriculture as being important, yet it is important that society be properly educated on issues in order to reach well-informed decisions and render prudent choices that impact the world around them. …

A Case Study Of Peer Assessment In A Mooc-Based Composition Course: Students’ Perceptions, Peers’ Grading Scores Versus Instructors’ Grading Scores, And Peers’ Commentary Versus Instructors’ Commentary, Lan Thi Vu

Dissertations

Although the use of peer assessment in MOOCs is common, there has been little empirical research about peer assessment in MOOCs, especially composition MOOCs. This study aimed to address issues in peer assessment in a MOOC-based composition course, in particular student perceptions, peer-grading scores versus instructor-grading scores, and peer commentary versus instructor commentary. The findings provided evidence that peer assessment was well received by the majority of student participants from their perspective as both peer evaluators of other students’ papers and as students being evaluated by their peers. However, many student participants also expressed negative feelings about certain aspects of …

(Re)Storying Ferguson: Youth Voices And Literate Lives, Katherine O'Daniels

Dissertations

This dissertation reports on a collaborative action research study conducted with Sioux Roslawski, a third-grade teacher in a Ferguson, Missouri elementary school. Sioux and I wondered how students might use words, images, and actions to shape a vision of their community space and its future in the aftermath of the Michael Brown shooting. Situated within a critical-spatial and sociocultural paradigm, placemaking stems from understandings of place as culturally produced and interpreted, and, thus, capable of being re-designed in the interest of equity and social justice. The research methodology was guided by a critical qualitative and ethnographic approach, coupled with critical …

Towards An Informatics Competent Nursing Profession: Validation Of The Self-Assessment Of Nursing Informatics Competency Scale (Sanics) Before And After Online Informatics Training, Judi Allyn Godsey

Dissertations

Nurses should be involved in healthcare initiatives that incorporate informatics as an essential tool for improving health outcomes (IOM, 2010). However, nurses frequently report lack of competency to perform the most basic computer functions, outside of those required within their work environment (Hwang, 2011). Without educational or training interventions, nurses are limited in their ability to effectively use information technology in practice (Greiner, 2003). This study explored the psychometric performance of the Self-Assessment of Nursing Informatics Competencies Scale (SANICS) when used to measure informatics competency in a population of entry-level nursing students.

Supervised Release Sentences Of Child Pornography Offenders In U.S. District Courts: An Examination Of Disparity, Niquita Marie Loftis

Dissertations

The statutory supervised release sentencing range for child pornography offenders convicted in U.S. District Courts is five years to life. However, the guideline policy statement contained in the Federal Sentencing Guidelines recommends lifetime supervision for all child pornography offenders. U.S. Sentencing Commission (USSC) data for fiscal year 2012 indicate that only approximately 33% of child pornography offenders were sentenced to lifetime supervision. This variation suggests the possibility of unwarranted supervised release sentencing disparities. The dissertation explores this possibility by examining the effects of individual-level legal and extralegal factors and district-level contextual factors on supervised release sentences for child pornography offenders. …

Increasing Resilience In Adolescent Nursing Students, Teresa Maggard Stephens

Dissertations

Nursing students not only face the same developmental challenges as other college students, but also experience unique stressors that contribute to increased risk for negative outcomes. The intimate nature of patient care, the exposure to workplace adversity, death and dying, and the chaotic nature of healthcare can have cumulative negative effects on students' health and well-being. Increased resilience could prove useful in helping students confidently face challenges and successfully move forward. The lack of empirical evidence regarding resilience-enhancing interventions with nursing students supports the need for examining the effectiveness of an educational intervention to increase resilience in adolescent baccalaureate nursing …
