Music preferences, music and non-music media use, and leisure involvement of Hong Kong adolescents.

Access: Use of this item is restricted to the UNT Community
The study sought to determine the relationships of preference responses to grade, gender, familiarity, musical training, peers'/parents' listening habits, music media use, and listening contexts. Grade six through nine Hong Kong students (N = 310) completed the audio preference test followed by verbal responses to training, peers'/parents' preferences, leisure/music media involvement, and listening context. Results indicated: The preferred genres, in descending order, were Western pop/rock, Cantopop/rock, Western classical; the disliked genres were jazz, Chinese, and non- Western/non-Chinese. Preference correlated strongly with genre familiarity. Pop genres were the most familiar to all adolescents. The students' preference toward Western pop/rock and Cantopop/rock associated with several listening contexts: solitary listening, having great freedom to choose one's desired music for listening, listening to music in one's room, and listening to music as background activity. The adolescents expressed that their leisure activities were spent with their family and friends. However, they made it clear that music listening was a personal activity that very likely was listened to alone. On all listening occasions, the girls exhibited a more positive response than the boys did. With four to five hours daily leisure time, the adolescents watched TV for three to four hours while spending less than two …

The Effects of Web-Based Learning Versus Traditional Instructor-Based Learning on Student Knowledge and Satisfaction Based on Student Learning Styles

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to compare the effects of Web-based learning (WBL) versus those of traditional instructor-based learning (IBL) on student knowledge and satisfaction based on student learning styles. Other goals were to determine if WBL is more effective for those with a particular learning style. The study examined a sample of undergraduate students who were enrolled in the college algebra offered as both oncampus instructor-based (traditional) and Web-based at the university of North Texas (UNT). A total of 36 Web-based students and 58 instructor-based students participated in this study. This study utilized a posttest-only intact group. The Kolb Learning Style Inventory (LSI) measured the learning styles of students. This study used learning methods (Web-based learning (WBL), instructor-based learning (IBL)), and learning styles (Diverger, Converger, Assimilator, and Accommodator) as independent variables. Student knowledge and student satisfaction was measured at the end of the course as independent variables. Based upon the results of the LSI, post-learning exam, and satisfaction a series of two-way analysis of variance (ANOVA 4x2) techniques and independent variable tests was used for each of the dependent variables, knowledge and satisfaction, based on a student's learning styles. The results revealed that students' learning styles were statistically …

The mediating and moderating effects of women's attachment style on interrelationships among emotional abuse, physical aggression and relational stability. (open access)

The mediating and moderating effects of women's attachment style on interrelationships among emotional abuse, physical aggression and relational stability.

This purpose of this study was to combine two bodies of literature on relationships, attachment and violence. Given the impact of men's physical aggression and emotional abuse on women, it is likely that these behaviors would also affect attachment. A model proposing that women's attachment style mediated and moderated the relationship between partners' physical and emotional abuse and the stability of women's relationships was tested. Archival data were used from two waves of interviews with a sample of lowincome, ethnically diverse community women. Most (89%) of the initial 835 participants of Project HOW: Health Outcomes of Women completed at least one additional interview providing information on the status of their initial relationships. Of these women, 39% were African American, 30% were Euro-American, and 31% were Mexican American. The effects of men's psychological abuse and physical violence on women's attachment style were tested with regression analyses. The interrelationships between partners' abuse, attachment and relational stability were tested with SEM. Attachment style was expected to moderate the associations among variables and mediate the impact of partners' negative behavior on relational stability. In regression analyses, partners' psychological abuse predicted avoidant and anxious, but not secure attachment ratings. Violence, although significant, explained less variance …

A Performer's Analysis of Lili Boulanger's Clairières dans le ciel: Song Cycle for High Voice and Piano; a Lecture Recital Together with the Role of Blanche in Dialogues of the Carmelites by F. Poulenc and Two Recitals of Selected Works by H. Purcell, F. Schubert, S. Prokofieff, E. Chausson, W. A. Mozart, R. Schumann and G. Fauré

Lili Boulanger was an important composer of early twentieth century French music. Her compositional style represents a development and mastery of musical techniques of the great composers of her time including Fauré, Debussy and Wagner combined with her own creative expression. The result is a compelling musical language that was uniquely her own. She held an important place among her contemporaries in Paris and her accomplishments were considered newsworthy during her lifetime (1893- 1918). She obtained a much sought-after publishing contract with Ricordi. Her more famous sister, Nadia Boulanger, felt that Lili was the better composer of the two, and her peers and music professors clearly felt that both her musical and personal qualities were extraordinary. Evidence of her intelligence, creativity, and artistic growth can be seen in her music. As the first woman to win the Prix de Rome (July 5, 1913), Lili Boulanger, unlike Clara Schumann, Fanny Mendelssohn, or Alma Mahler, was acknowledged and acclaimed during her lifetime for her skill as a composer. Yet, nearly a century later the music of this talented French composer is not as well known as it deserves to be. In an effort to discover the reasons for this relative anonymity, this …

Selected Songs for Chamber Winds and Soprano: Rediscovering a Forgotten Repertoire of John Philip Sousa

Access: Use of this item is restricted to the UNT Community
For over one hundred years, the music-going public has reflected on the life and influence of America's “March King,” John Philip Sousa. His popularity as a bandleader was unprecedented, and his reputation as an entertainer captivated the imagination and intrigue of a nation. Sousa's fame was attained through the high standards showcased by his unparalleled concert organization, the Sousa Band. He is interminably linked to the march, and for his seventy-seven years he proved to be its prolific and outspoken champion. Sousa's songs, however, were among his favorite works, and their presence on concert programs reinforced a variety of programming that was the hallmark of his success. The Sousa Band served as a cultural and musical ambassador, and annual transcontinental tours brought music to people where they lived. Sousa's songs were highly anticipated concert features, and were presented by soprano soloists known as the “Ladies in White.” A chamber winds instrumentation, rather than employment of the full-forces of the Sousa Band, allowed for an appropriate musical balance between instruments and voice. The “Forgotten Songs of John Philip Sousa Project” involved the research, editing, and performance of songs housed in the Sousa Archives for Band Research at the University of Illinois. …

Investigations of neuronal network responses to electrical stimulation in murine spinal cultures. (open access)

Investigations of neuronal network responses to electrical stimulation in murine spinal cultures.

Spontaneous activity in neuronal networks in vitro is common and has been well documented. However, alteration of spontaneous activity in such networks via conditioning electrical stimulation has received much less experimental attention. Two different patterns of electrical stimulation were used to enhance or depress the level of spontaneous activity in spinal cord cultures. High-frequency stimulation (HFS), a method routinely shown to increase the efficacy of synaptic transmission, was employed to augment spontaneous activity. Low-frequency stimulation (LFS), the technique often applied to depress synaptic efficacy, was employed to decrease spontaneous activity. In addition, LFS was used to reverse the effect of HFS on spontaneous activity. Likewise, HFS was applied to counter the effect of LFS. Because these networks were grown on multi-microelectrode plates (MMEPs), this allowed the simultaneous stimulation of any combination of the 64 electrodes in the array. Thus, the possible differences in response to single versus multi-electrode stimulation were also addressed. Finally, test-pulses were delivered before and after the conditioning stimulation on the same stimulation electrode(s) in order to assess the change in mean evoked action potentials (MEAPs). Dissociated spinal tissue from embryonic mice was allowed to mature into self-organized networks that exhibited spontaneous bursting activity after two weeks …

Attitudes of American and Korean Early Childhood Educators Regarding Programs for Gifted/Talented Young Children.

The purpose of this research was to study the attitudes of Korean and American early childhood educators concerning gifted children and programs aimed specifically at meeting their needs. The study examined general attitudes towards giftedness and gifted education programs and factors that might affect those attitudes. The study also examined desirable environments for young gifted children. Twenty-item questionnaires were developed and logically divided into six sections (identification, teacher environment, classroom environment, parent environment, educational rights, and program). A systematic process of development, analysis, and refinement of the questionnaire was done. The questionnaires were given randomly to American educators attending the 1996 National Association for the Education of Young Children (NAEYC) conference. A random Korean sample included early childhood educators listed in the Korean Association for Early Childhood Education Directory (1995-1996) and the Korean Association for Child Care Directory (1995-1996). All subjects were members of one of three groups: (a) teacher educators, (b) teachers, and (c) administrators/directors. The surveys found agreement between Korean and American early childhood educators on the importance of knowing the strengths of individual gifted children, the need to stimulate higher order thinking skills, the rights of gifted children to an appropriate education, a perception of more work …

Effect of Individualized Curricular Accommodations, Incorporating Student Interest and the Impact on the Motivation and Occurrence/ Nonoccurrence of Disruptive Behavior Displayed By Students with Emotional/behavioral Disorders.

As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for …

Accounting for Human Resources: Implications for Theory and Practice.

Knowledge workers are an important resource for the typical modern business firm, yet financial reporting ignores such resources. Some researchers contend that the accounting profession has stressed reliability in order to make the accounting appear objective. Others concur, noting that accounting is an insecure profession and adopts strict rules when faced with uncertainty. Accountants have promulgated a strict rule to expense human resource costs, although many know that such resources have future benefits. Some researchers suggest that any discipline must modify its language in order to initiate change toward providing useful social ameliorations. If accounting theorists extend this idea to the accounting lexicon.s description of investments in human resources, investors and other accounting user groups might gain greater insight into how a firm fosters and nourishes human capital. I tested three hypotheses related to this issue by administering an experiment designed to assess financial analysts. perceptions about alternative financial statement treatments of human resources in an investment recommendation task. I predicted that (1) analysts' perceptions of the reliability (relevance) of the information they received would decrease (increase) as the treatment of human resources increasingly violated GAAP (became more current-oriented), (2) analysts exposed to alternative accounting treatments would report a lower …

The Stopping of Energetic Si, P and S Ions in Ni, Cu, Ge and GaAs Targets

Access: Use of this item is restricted to the UNT Community
Accurate knowledge of stopping powers is essential for these for quantitative analysis and surface characterization of thin films using ion beam analysis (IBA). These values are also of interest in radiobiology and radiotherapy, and in ion- implantation technology where shrinking feature sizes puts high demands on the accuracy of range calculations. A theory that predicts stopping powers and ranges for all projectile-target combinations is needed. The most important database used to report the stopping powers is the SRIM/TRIM program developed by Ziegler and coworkers. However, other researchers report that at times, these values differ significantly from experimental values. In this study the stopping powers of Si, P and S ions have been measured in Ni, Cu, Ge and GaAs absorbers in the energy range ~ 2-10 MeV. For elemental films of Ni, Cu and Ge, the stopping of heavy ions was measured using a novel ERD (Elastic Recoil Detection) based technique. In which an elastically recoiled lighter atom is used to indirectly measure the energy of the incoming heavy ion using a surface barrier detector. In this way it was possible to reduce the damage and to improve the FWHM of the detector. The results were compared to SRIM-2000 predictions …

Quantization Dimension for Probability Definitions

Access: Use of this item is restricted to the UNT Community
The term quantization refers to the process of estimating a given probability by a discrete probability supported on a finite set. The quantization dimension Dr of a probability is related to the asymptotic rate at which the expected distance (raised to the rth power) to the support of the quantized version of the probability goes to zero as the size of the support is allowed to go to infinity. This assumes that the quantized versions are in some sense ``optimal'' in that the expected distances have been minimized. In this dissertation we give a short history of quantization as well as some basic facts. We develop a generalized framework for the quantization dimension which extends the current theory to include a wider range of probability measures. This framework uses the theory of thermodynamic formalism and the multifractal spectrum. It is shown that at least in certain cases the quantization dimension function D(r)=Dr is a transform of the temperature function b(q), which is already known to be the Legendre transform of the multifractal spectrum f(a). Hence, these ideas are all closely related and it would be expected that progress in one area could lead to new results in another. It would …

Introduction contains a brief historical background of musique concrète, Electronische Musik, acousmatic music and music for instruments and tape, followed by basic descriptions of digital technique used in both parts of Summer Rain in Chapter 2. Also Chapter 2 describes software used in Summer Rain including "Kawamoto's VST," which is based on MAX/MSP, to create new sounds from the recorded samples using a Macintosh computer. In both Chapter 3 and 4, Kawamoto discusses a great deal of the pre-compositional stage of each piece including inspirational sources, especially Rainer Maria Rilke's poems and Olidon Redon's paintings, as well as her visual and sound imageries. In addition Chapter 3 she talks about sound sources, pitch, form and soundscape. Chapter 4 contains analysis on pitch in the piano part, rhythm, form and the general performance practice. Chapter 5 is a short conclusion of her aesthetics regarding Summer Rain, which is connected to literature, visual art and her Japanese cultural background.

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to explore the use of EEG biofeedback in a school setting to assist students who had attentional challenges. The equipment for implementing biofeedback was relatively inexpensive and was easily integrated into the school setting. Twenty students ranging in age from 7 to 17 were recruited for this study. Data was used from 14 subjects, 12 males (2 Hispanic, 1 African American, and 10 Caucasian) and 2 females (1 Hispanic, 1 Caucasian.) The subject pool was reduced due to non-compliance or the students. moving from the school district. Significant effect size was obtained in the treatment group in areas pertaining to visual perception and motor coordination. However, significant effect sizes in other areas were obtained when the control group scores worsened. The inclusion of student subjects who, perhaps, did not meet stringent criterion of attention deficit may have skewed the results. The small number of students in the study may have hindered accurate measures of statistical significance. Conversely, the information obtained from this study may offer insight to school districts in providing their students an alternate/adjunct to psychopharmacological medication and a non- invasive method of helping students with psycho-social challenges.

Similarities in the Use of Dramatic Recitative Style in the Music of Claudio Monteverdi and Giuseppe Verdi, with Some Performance-Practice Issues

The objective of this dissertation, inspired by performance experience, was to establish the similarities in the use of recitative style in the music of Claudio Monteverdi and Giuseppe Verdi. To achieve this objective, their use of recitative style was examined through comparative analysis of four scenes from their operas: “Arianna's Lament” from L'Arianna and “Disprezzata regina” from L'incoronazione di Poppea by Monteverdi, and “Condotta ell'era in ceppi” from Il trovatore and “Judgment Scene” from Aida by Verdi. The examination of the similarities included a discussion of the following: (a) the historical influences and cultural backgrounds of the composers; (b) general similarities in their compositional approaches to recitative style; (c) comparable characteristics of the dramatic recitative style in the early Baroque monody and in Verdi's operas; (d) similarities in musical characterization and expression of affective and emotional content through stylistic musical devices; (e) similarities in the composers' approaches to vocal and acting issues with special emphasis on the problems of diction; and (f) some related performance-practice issues. A discussion of the poetic lament and the influence of its form and content on musical setting was also a part of this research. The comparative research revealed numerous similarities in the historical circumstances …

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items.

Mass media such as television, video players, video games, compact disks, and the computers are commonplace in current American culture. For English as a Second Language children, television may be the only source of English in the home serving as models of grammar, syntax, story structure. An investigation was made using English as a Second Language (ESL) kindergarteners, the classroom writing center, participant-observation, teacher as researcher, and case study methodology to investigate the following questions: Do ESL kindergarten children use media in their writing? If so, how do they use media in their writing? Upon examination of the data, it was found that all these ESL children did use media in the writing process. The function and form of the media references varied from child to child. Media was a cultural context for the childrenÕs social interactions. Oral language (with and without media references) not only informed the writing for some, but also served: to initiate, participate in, and sustain social relationships with peers. Findings indicated that two case study subjects used social dialogue as a separate operation from the production of a written story. Language informed the writing but it also had a socialization function in addition to what …

Minorities, gender, managerial jobs, and income, 1960-1990

Changes in income and representation in managerial occupations is explored separately for women and men among the United States' eight largest race/ethnic minority groups for each decennial census of 1960, 1970, 1980 and 1990 to determine how much change has occurred between 1960 and 1990 in race and ethnic inequality, and in gender inequality within each race/ethnic group. Insights from gender theory are applied to minority group inequality and insights from minority group theory are applied to gender inequality with some degree of success. Economic change is uneven among the groups, with the largest specific change being the movement of women into managerial jobs. A clear pattern also emerged indicating that the higher the average representation of a minority group in managerial jobs, the greater the gap between women and men. The income of all persons with income, however, did not exhibit such a clear pattern across the different groups.

John Graves and the Pastoral Tradition (open access)

John Graves and the Pastoral Tradition

John Graves's creative non-fiction has earned him respect in Texas letters as a seminal writer but scarce critical commentary of his work outside the region. Ecological criticism examines how language, culture and the land interact, providing a context in which to discuss Graves in relation to the southwestern literary tradition of J. Frank Dobie, Walter P. Webb, and Roy Bedichek, to southern pastoral in the Virgilian mode, and to American nature writing. Graves's rhetorical strategies, including his appropriation of form, his non-polemical voice, his experimentation with narrative persona, and his utilization of traditional tropes of metaphor, metonymy, and irony, establish him as a conservative and Romantic writer of place concerned with the friction between traditional agrarian values and the demands of late-twentieth-century urban/technological existence. Sequentially, Graves's three main booksGoodbye to a River (1960), Hard Scrabble (1974), and From a Limestone Ledge (1980)represent a movement from the pastoral mode of the outward journey and return to the more domestic world of georgic, from the mode of leisure and contemplation to the demands and rewards of hard work and ownership. As such they represent not only progression or maturation in the arc of the narrator's life but a desire to reconcile ideological …

The relationship of attachment and shame to anorexia: A case study comparing restrictive and normal eaters (open access)

The relationship of attachment and shame to anorexia: A case study comparing restrictive and normal eaters

Research has described and many clinicians have reported the anorectic patient as socially disconnected, having a disembodied sense of self, perfectionist expectations, and inadequate and shameful feelings. The more intense the internal war, the more food-focused and self-defeating behavior ensues, thwarting one's ability to receive value, self-acceptance, and love. Addressing the anorexia phenomenon, this study considered, from a sociological perspective, the dynamics of attachment and shame. On the basis of 4 propositions and using a multi-method, case-replication design, attachment and shame patterns for 5 restrictive and 5 normal eaters were compared, as determined by scores from the Parental Bonding Instrument, Inventory of Parental and Peer Attachment, Internalized Shame Scale, and personal interviews. Analysis was progressive, as propositions were tested by pattern-matching steps of rating, comparing, and interpreting recurring responses to self-report and interview questions. All anorectics reported a dominant mother, with whom 4 were over attached and struggled ambivalently for autonomy, and a quiet, inexpressive father, whom 4 considered frequently absent or unavailable. As compared to normal eaters, anorectics' trust and communication scores were lower for both parents and peers. Generally, anorectics showed markedly higher internalized shame. Findings indicated that nonoptimal parental bonding patterns were related to shame. The maternal …

Historical Changes in Elderly Cohorts' Attitudes toward Mental Health Services

Older adults' attitudes toward mental health services have received little research attention. Overall, older adults are thought to hold relatively negative attitudes. In this study, Analysis 1 investigated historical shifts in attitudes toward mental health services among three independent samples of older adults, separated by 14-year and 9-year intervals (1977 sample, N = 90; 1991 sample, N = 101; 2000 sample, N = 99). Analysis 2 compared two samples of older and younger adults, each separated by a 9-year interval (Older Adults: 1991 sample, N = 93; 2000 sample, N = 91 and Younger Adults: 1991 sample, N = 131; 2000 sample, N = 147). Participants completed a questionnaire containing five, internally consistent scales assessing multiple dimensions of mental health attitudes (Openness, Biases, Range of Knowledge, Breadth, Help Seeking Attitudes). Analyses suggested that the 1991 and 2000 samples of older adults had more positive attitudes than did the 1977 sample. However, a sustained trend for more positive attitudes beyond 1991 was not seen. In fact, no differences existed between 1991 and 2000 samples with exception of two. Older and younger adults together had lower Biases and Breadth scores in 2000 than in 1991. Age effects, gender effects, and interactions were …

Higher Compression from the Burrows-Wheeler Transform with New Algorithms for the List Update Problem

Burrows-Wheeler compression is a three stage process in which the data is transformed with the Burrows-Wheeler Transform, then transformed with Move-To-Front, and finally encoded with an entropy coder. Move-To-Front, Transpose, and Frequency Count are some of the many algorithms used on the List Update problem. In 1985, Competitive Analysis first showed the superiority of Move-To-Front over Transpose and Frequency Count for the List Update problem with arbitrary data. Earlier studies due to Bitner assumed independent identically distributed data, and showed that while Move-To-Front adapts to a distribution faster, incurring less overwork, the asymptotic costs of Frequency Count and Transpose are less. The improvements to Burrows-Wheeler compression this work covers are increases in the amount, not speed, of compression. Best x of 2x-1 is a new family of algorithms created to improve on Move-To-Front's processing of the output of the Burrows-Wheeler Transform which is like piecewise independent identically distributed data. Other algorithms for both the middle stage of Burrows-Wheeler compression and the List Update problem for which overwork, asymptotic cost, and competitive ratios are also analyzed are several variations of Move One From Front and part of the randomized algorithm Timestamp.

The relationship between models of student laptop computer use and teacher instructional behavior

This study investigated the relationship between four models of student laptop computer use and three components of teacher instructional behavior: planning, implementation of instruction, and evaluation of instruction. The four models of use: full access, dispersed, class set, and mixed, represented the numerous ways teachers in public and private schools and school districts nationwide implemented student use of laptop computers. Teacher planning behavior was investigated with regard to time, frequency, complexity, difficulty, the need for revision, and use of technological resources and materials. Implementation of instruction was examined with regard to student grouping, instructional strategies, instructional content/subject matter, teacher and student roles, assignments and learning tasks, and instructional activities. The evaluation of instruction component was examined with regard to assessment tasks, grading, and assessment of homework. Using a researcher-designed questionnaire, data was gathered in a single-stage cross-sectional survey from 356 teachers working in 74 public and private schools nationwide. Results indicated models of student laptop computer use had differential effects on teacher instructional behaviors. On average, teachers found planning to be more arduous, but more collegial, especially in the mixed model. The full access and mixed models were more likely to advance a constructivist approach to teacher instructional behaviors with …

The Assessment of Cognitive Development and Writing Aptitude Within Learning Communities (open access)

The Assessment of Cognitive Development and Writing Aptitude Within Learning Communities

Learning communities have emerged as an efficient and effective paradigm for improving undergraduate education, especially for entering freshmen. The academy has become increasingly interested in learning outcomes and student retention, especially as they are related to the assessment of various approaches to educating the whole student. Learning community pedagogy has developed through rigorous research. However, little is known about the impact of this pedagogy upon college students' cognitive development and writing aptitude. Cognitive development theory has been most significantly influenced by the work of William G. Perry, Jr. Though no theory exists which would address the stages of writing development in university students, many composition theorists suggest a correlation between cognitive development and writing aptitude. This study measured cognitive development and writing aptitude in learning community students and non-learning community students, matching them for SAT scores, high school grade point averages, gender, and ethnicity. The research questions of interest were: 1) How does participation in a learning community affect students' cognitive development; and 2) How does participation in a learning community affect students' writing aptitude?
