Effect Of Small Class Setting On The Algebra I Achievement Of Ninth-Grade Students, Lisa Kissire

Dissertations

The effects of class size on student outcomes has been widely studied at the elementary level. Many such studies have found important relationships between class size and outcome in the areas of academic achievement, student discipline, and teacher retention. However, little attention has been given to the examination of how class size may affect student outcomes in the middle school and high school levels. The purpose of this nonexperimental study was to examine the effects of class size setting, gender, socioeconomic status, and school configuration on the Algebra I achievement of ninthgrade students. Participants were drawn from four rural schools …

An Analysis Of The Act Sub-Scores’ Ability To Predict The Outcome Of College Algebra Through The Lens Of Modern Chaos Theory, Johnathan Jay Mcewen

Dissertations

ACT scores are widely used to predict outcomes in coursework and serve as placement guidelines for college level courses such as college algebra. Due to a changing college environment, the appropriateness of these placement decisions takes on a new, more critical light. Given the rate of success for current predictions in college algebra, and the resulting consequences for misplacement, this study examines the predictive potential of the ACT scores through the examination of non-linear variables and a metaphorically chaotic interpretational lens.

The literature base for this study reveals, almost to exclusion, the use of linear models for the prediction of …

Analysis Of Professors’ Perceptions Towards Institutional Redevelopment Of Brownfield Sites In Alabama, Berkley Nathaniel King Jr.

Dissertations

This study was conducted to analyze professors’ perceptions on the institutional redevelopment of brownfield sites into usable greenspaces. The U.S. Environmental Protection Agency (2011) refers to brownfields as sites, (either facility/land) under public law § 107-118 (H.R. 2869), which are contaminated with a substance that is classified as a hazard or a pollutant. Usable greenspaces, however, are open spaces or any open piece of land that is undeveloped, has no buildings or other built structures, and is accessible to the public (EPA, 2015).

Open green spaces provide recreational areas for residents and help to enhance the beauty and environmental quality …

The researcher used four middle school science teachers and nine high school science teachers, all from inner city schools in a big city of the Midwest United States except for one middle school teacher from a nearby suburb. The participants answered a survey questionnaire followed with a face-to-face recorded interview. The findings of the study confirmed that students showed little interest in science due …

Measuring The Effectiveness Of A Two-Period Algebra Class: A Program Evaluation, Tracey K. Landry

Dissertations

This paper details a program evaluation of a two-period freshman Algebra course in a two-high school district. The study examines the degree to which the two-period course is an effective intervention for freshman math students as compared to the one-period freshman Algebra course by reviewing student assessment data, student growth indicators, and course enrollment data. In addition to quantitative data, student, teacher, and administrator perceptions of the course inform the investigation into the two-period remedial math class. The paper concludes that the two-period math program is not having the desired impact and should be reconfigured or reconsidered altogether.

A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson

A Quantitative Analysis Of Whether Elementary Teachers’ Science Kit Usage And Beliefs Can Predict State Science Assessment Scores, Tony E. Rice

Dissertations

The purpose of this survey was to describe and analyze the perceptions of elementary school teachers’ in a Midwestern state concerning their use of a science kit program, including to what extent a school’s state science assessment scores can be predicated from the level of science kit usage.

Prior research indicates that elementary school teachers lack the confidence in teaching science primarily because of their weak undergraduate training in inquiry-based instruction and the lack of a strong science background. Authors such as Dickerson et al. (2006) and Riggs and Enochs (2006) argued that science kits and the materials included in …

Females In Automotive Careers: Career Decision-Making Influences And Experiences During University Preparation And Beyond, Russell A. Leonard Jr.

Dissertations

Today, women fill nearly 50% of the jobs in the U.S. economy (U.S. Dept. of Labor, 2014). While women are making progress in many careers once considered male only, they are still underrepresented in the male-dominated Science, Technology, Engineering, and Math (STEM) careers, filling only 25% of available STEM jobs (Beede et al., 2011). The problem is not a lack of interest in STEM subjects, but a “leaky pipeline” that develops early in adolescence. By the eighth grade, half as many girls are interested in STEM careers as boys (National Science Foundation [NSF], 2007). Even after graduation from college, women …

Guided Educational Tourism As Informal Science Education: An Empirical Study, Joseph Martin Lane

Dissertations

The scientific research and education communities have long had the goal of advancing the publics’ understanding of science. Informal science education is a powerful mechanism for shaping human conduct, enhancing quality of life, and advancing the publics’ understandings and values regarding science. Guided educational tours (that present science content) provide visitors with unique opportunities to observe and discuss scientific phenomena in the field. Available empirical research related to learning science from guided educational tours is, at best, limited. Research leading to the development of effective guided educational tours that present and interpret scientific information is of interest to both non-profit …

Effects Of Traditional High School Versus Career Academy High School On Literacy And Mathematics Achievement, Dana Brown

Dissertations

The purpose of this dissertation was to determine the effects by gender and by socioeconomic status between students in career academy high schools versus students in traditional high schools on literacy and mathematics achievement for 8th-11th grade students in 6A and 7A high schools in the state of Arkansas. In the context of this study, relevance has to do with the connection or link established between something learned and an opportunity to apply that learning. Critics of the traditional learning structure argue that because information is learned in isolation, a difficulty arises in how that learning is readily applicable to …

The data indicated that administrators believed that 8^th grade student performance …

Supplemental Action Learning Workshops: Understanding The Effects Of Independent And Cooperative Workshops On Students’ Knowledge, Kathryn M. Morris

Dissertations

Community colleges enroll more than half of the undergraduate population in the United States, thereby retaining students of varying demographics with extracurricular demands differing from traditional four-year university students. Often in a collegiate lecture course, students are limited in their abilities to absorb and process information presented by their instructors due to content-specific cognitive gaps between the instructor and the student (Preszler, 2009). Research has shown implementation of instructor-facilitated action learning workshops as supplemental instruction may help bridge these cognitive gaps allowing better student conceptualization and dissemination of knowledge (Drake, 2001; Fullilove & Treisman, 1990; Preszler, 2009; Udovick et al., …

Assessing The Impact Of Historical Story Telling On Student Learning Of Natural Selection, Janice Marie Fulford

Dissertations

Research suggests that because of its historical nature, the learning of evolutionary biology is problematic compared to that of other science disciplines. While explanations used in historical sciences often employ historical narratives, which are distinct from narratives in other contexts, such as stories, the two types of narratives have structural similarities that suggest the potential role of stories based in the history of science for the teaching of evolutionary biology. Stephen Klassen, a prominent science educator, has studied how stories from the history of physics can promote the learning of and attitudes towards science. Klassen’s pioneering work identifies structural components …

Transformative Models In K-12 Education: The Impact Of A Blended Universal Design For Learning Intervention, Kai Monet Mathews

Dissertations

Accountability measures, by way of standardized curriculum and assessments, have played a large part in the attempt to ensure that students from all backgrounds receive equal access to quality education. However, the inherent disadvantage of a standardized system is the implied assumption that all students come in with the same knowledge, learn at the same pace, and learn the same way. In the wake of an increasingly diverse K-12 population, educational researchers, learning theorists, and practitioners agree that the concept of the average student is, in fact, a myth. Students come to school with different needs, norms, interests, cultural behavior, …
