The Relationship Between Time-on-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

The Relationship Between Time-on-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

Date: December 1999
Creator: Lansford, Carl Edwin
Description: This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students. Difference between the ...

The Response of a Public School District to Charter School Competition: An Examination of Free-Market Effects

The Response of a Public School District to Charter School Competition: An Examination of Free-Market Effects

Date: December 1999
Creator: Patrick, Diane Porter
Description: The purpose of this study was to examine a school district's responses to charter schools operating within its boundaries. The selected district was the only one in the state with two large academically competitive charter schools for at least two years. Four questions guided the research: In terms of instruction, finance, communication, and leadership, how has the traditional district been impacted due to charter school existence? The exploratory research was timely since charter schools are proliferating as tax-supported public choice schools. While many have speculated about free-market effects of charter school competition on systemic educational reform, the debate has been chiefly along ideological lines; therefore, little empirical research addresses this issue. Quantitative and qualitative methodologies were used to present a comprehensive case study. Twenty-six school officials and teachers were interviewed; 159 teachers and 1576 parents were surveyed. District, community, and state education department documents were analyzed. Since charter schools have existed in the district, numerous activities have taken place. Instructional initiatives included a high school academy, expanded technology, gifted and talented, tutoring, and dropout prevention. All elementary and middle schools required uniforms. The district's state accountability rating improved from acceptable to recognized. A leadership void was perceived due to students ...

The Resurrexit from Hector Berlioz's Messe solennelle (1825): A Case Study in Self-Borrowing

The Resurrexit from Hector Berlioz's Messe solennelle (1825): A Case Study in Self-Borrowing

Date: December 1999
Creator: Gill, Sarah M.
Description: Hector Berlioz's Messe solennelle, his first publicly performed work, was important to his establishment in Paris as a composer. Although he later destroyed the Mass, he reused parts of the Resurrexit movement in three of his later works: Benvenuto Cellini (1836), the Grand messe des morts (1837), and the Te Deum (1849). This study examines the Resurrexit and its subsequent borrowings. In each instance that Berlioz borrowed from the Resurrexit, he extracted large sections and placed them in the context of later works. Each time that borrowing occurred, Berlioz constructed the surrounding music so that portions from the Resurrexit would fit stylistically and a seamlessly into the texture. In each borrowing, he left the melody unaltered, changing harmony and orchestration instead. This pattern of borrowing demonstrates that Berlioz developed his concept of melody early in his career, and that his method of self-borrowing was consistent in each subsequent use of the Resurrexit.

Revealing what urban early childhood teachers think about mathematics and how they teach it: Implications for practice

Revealing what urban early childhood teachers think about mathematics and how they teach it: Implications for practice

Date: December 1999
Creator: Hare, Addie Y. V. McGriff
Description: Hersh (1986) states, "One's conception of what mathematics is affects one's conception of how it should be presented. One's manner of presenting it is an indication of what one believes to be most essential in it." In this research study, three hundred ninety-seven urban early childhood teachers were given a survey that examined their attitudes toward mathematics and mathematics teaching, their views of mathematics, views of teaching mathematics, and views of children learning mathematics. The purpose of this study was to identify the attitudes and beliefs of early childhood teachers in two urban school districts to determine if mathematics reform efforts made a difference in teachers' attitudes and beliefs about mathematics and its teaching. Questionnaires were mailed directly to teachers in one school district and principals distributed questionnaires in the other. Summary scores were calculated for parts of the instrument. The researcher performed descriptive statistics, comparative analysis, and conducted frequency distributions, t-tests, ANOVA, and Pearson Correlations. Findings revealed that teachers with 30 or more years of teaching experience had more positive attitudes toward mathematics than teachers with 1-3 years of experience. African American teachers had more positive attitudes toward mathematics and its teaching than other ethnic groups. Teachers who held ...

Scientific Considerations of Olestra as a Fat Substitute

Scientific Considerations of Olestra as a Fat Substitute

Date: December 1999
Creator: Rattagool, Kullakan
Description: Olestra is, a sucrose polyester, a noncaloric fat substitute, made from sucrose and several fatty acid esters. It has been approved by the FDA as a food additive used in preparing low-fat deep-frying foods such as savory snacks. Available literature on olestra was evaluated that had both positive and negative connotations. Clinical trials in numerous species of animals including humans were conducted to determine if olestra would affect the utilization and absorption of macro- and micronutrients; the effects of olestra on growth, reproduction, or its toxicity were also examined. The roles of olestra as a fat substitute, how it could effect on humans and the environment, and the potential impacts from its use in large amounts were assessed. Olestra can be removed from the environment by aerobic bacteria and fungi which may be isolated from activated sludge and soils.

A sensory tour of Cape Cod, Thoreau's transcendental journey to spiritual renewal

A sensory tour of Cape Cod, Thoreau's transcendental journey to spiritual renewal

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Talley, Sharon
Description: Predominantly darker than his other works, Cape Cod depicts Henry David Thoreau's interpretation of life as a struggle for survival and a search for salvation in a stark New England setting. Representing Thoreau's greatest test of the goodness of God and nature, the book illustrates the centrality of the subject of death to Thoreau's philosophy of life. Contending that Thoreau's journey to the Cape originated from an intensely personal transcendental impulse connected with his brother's death, this study provides the first in-depth examination of Thoreau's use of the five senses in Cape Cod to reveal both the eccentricities inherent in his relationship with nature and his method of resolving his fears of mortality. Some of the sense impressions in Cape Cod--particularly those that center around human death and those that involve tactile sensations--suggest that Thoreau sometimes tried to master his fears by subconsciously altering painful historical facts or by avoiding the type of sensual contact that aggravated the repressed guilt he suffered from his brother's death. Despite his personal idiosyncrasies, however, Thoreau persisted in his search for truth, and the written record of his journey in Cape Cod documents how his dedication to the transcendental process enabled him to surmount ...

Structural analysis of the TOL pDK1 xylGFJQK  region and partial characterization of the xylF and xylG gene products

Structural analysis of the TOL pDK1 xylGFJQK region and partial characterization of the xylF and xylG gene products

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Poulter, Melinda D.
Description: TOL plasmids encode enzymes responsible for utilization of toluene and related aromatic compounds by Pseudomonas putida, ultimately converting them to central metabolic intermediates. The nucleotide sequence for the 5.6 kb xylGFJQK region of the pDK1 TOL meta operon was determined. DNA sequence analysis revealed the presence of five open reading frames corresponding to xylG (1458 bp), xylF (846 bp), xylJ (783 bp), xylQ (936 bp) and xylK (1047 bp), encoding predicted protein products of 51.6, 31.3, 27.8, 32.8, and 36.6 kDa in size, respectively. The average G+C content of the xylLTEGFJQK region was 65.7%, somewhat higher than the 58.9% seen in the immediately upstream xylXYZ region and substantially more than the 50% G+C content reported for the upper TOL operon of this plasmid. Homology comparisons were made with genes and proteins of related catabolic plasmids. The dmpCDEFG and pWWO xylGFJQK regions exhibit consistently high levels of nucleotide and amino acid homology to pDK1 xylGFJQK throughout the entire region. In contrast, although the nucleotide sequence homology of the Acinetobacter atdCDE region to xylGFJ is high, the homology of atdFG to xylQK is markedly less. Such radical changes in homology between corresponding regions of different operons, combined with variable base and codon ...

Structural holes and Simmelian ties: Exploring social capital, task interdependence, and individual effectiveness

Structural holes and Simmelian ties: Exploring social capital, task interdependence, and individual effectiveness

Date: December 1999
Creator: Engle, Scott L.
Description: Two contrasting notions have been put forward on how social capital may influence individual effectiveness in organizations. Burt (1992) sets forth the informational and control advantages that are possible by building an open network characterized by large numbers of structural holes. In contrast, Coleman (1990) and Simmel (1950) have suggested that network closure, exemplified by large numbers of Simmelian ties, enables actors to develop trust, cohesiveness, and norms which contribute to effectiveness. Simmelian ties are strong, reciprocal ties shared by three actors. It is proposed that an actor's network cannot be dominated by both structural holes and Simmelian ties. Thus, this study examines whether a moderating variable is at work. It is proposed that the actor's task interdependence in the workplace influences the relationship between network closure and individual effectiveness. Actors in less task interdependent environments will benefit especially from the information and control benefits afforded by a network characterized by structural holes. Conversely, actors in highly interdependent environments will benefit especially from the creation of trust and cooperation that result from large numbers of Simmelian ties. Data was collected on 113 subjects in three organizations. Subjects were asked to rate the strength of their relationship with all organization members ...

A Study of Franz Liszt's Concepts of Changing Tonality as Exemplified in Selected "Mephisto" Works

A Study of Franz Liszt's Concepts of Changing Tonality as Exemplified in Selected "Mephisto" Works

Date: December 1999
Creator: Kim, Jung-Ah
Description: The purpose of this study is to analyze four late solo piano works of Franz Liszt that all bear the name "Mephisto" in their titles, in order to examine, identify and trace the development in the use of harmonic and melodic idioms that produced non-tonal or "omnitonic" effects, on the one hand, and to emphasize the need to duly accord Liszt a recognition of historical position as the nineteenth century's most influential avant garde composer whose attitude and approach had helped to shape much of the ideal of the atonal composition of this century, on the other. Chapter One presents the issues and the purpose of this study; Chapter Two investigates the principal forces that shaped Liszt's mature compositional style; Chapter Three identifies and discusses the requisites for tonal and atonal compositions; Chapter Four analyzes the four "Mephisto" dances: Waltz no.1 (1860); Polka (1883); Waltz no.3 (1883); and Bagatelle (1885). Chapter Five summarizes the findings from this study and attempts to identify in these late works of Liszt a pattern of conscientious, continuous, purposeful and progressive use of devices toward creating musical effect that would defy the established tonal requisites and undermine the tonal orientation in the composition. This study ...
