A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form (open access)

A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form

When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Johnson, and Johnson (1981). Specific conditions included assorted combinations of the following factors: k=2 and k=3 groups, normal and non-normal distributional forms, similar and dissimilar distributional forms, and equal and unequal sample sizes. Under the k=2 group condition, a total of 180 combinations were examined. A total of 54 combinations were examined under the k=3 group condition. The Type I error rates and statistical power estimates were based upon 1000 replications in each combination examined. Results of this study suggest that when sample sizes are relatively large, all five procedures are robust to distribution non-normality and dissimilarity, as well as being sufficiently powerful.

A Descriptive Study of a Native African Mental Health Problem Known in Zimbabwe as zvirwere zvechivanhu (open access)

A Descriptive Study of a Native African Mental Health Problem Known in Zimbabwe as zvirwere zvechivanhu

This is a study conducted in Zimbabwe which compared a group of 50 zvirvere zvechivanhu patients and a group of 50 non-patients in age, sex, marital status, level of education and claims of spirit possession. Claims of spirit possessions and types of spirits, as pointed out by Bennel (1982), were used as symptoms of zvirwere zvechivanhu. The two groups were also compared in symptom dimensions of the SCL-90-R used in the study. The SCL-90-R, developed by Derogatis (1975), is a 90-item symptom check list used to screen people for psychological problems reflected in the nine symptom dimensions of somatization, obsessive/ compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism and in the three global scores of Global Severity Index, Positive Symptom Distress Index and Positive Symptom Total. The subjects were chosen from two different sites, using a systematic sampling method. Three statistical methods were used to analyze the data. The Chi-square was used to analyze data on descriptive variables. The T-test and 2 x 2 analysis of variance were used to analyze the data on symptom dimensions and global scores. The study had one main hypothesis and nine subhypotheses. The main hypothesis was that zvirwere zvechivanhu patients were …

The Effect of the Conflict Between Instructional Leadership and Building Management Roles on Job Satisfaction of the Texas Public High School Principal (open access)

The Effect of the Conflict Between Instructional Leadership and Building Management Roles on Job Satisfaction of the Texas Public High School Principal

The problem of this study was the conflict perceived by Texas Public High School Principals involving two roles which have been described as contradictory in nature; namely as an instructional leader and as a building manager. This study was also concerned with the level of job satisfaction of the Texas Public High School Principal. 1,205 Texas Public High School Principals identified by the Texas Education Agency and University Interscholastic League were mailed a three part questionnaire survey. 700 principals (or 58.09% of the entire population) returned the completed surveys. The questionnaire "Demographic Survey for Texas Public High School Principals" consisted of eight questions. The thirty-four statement "Questionnaire for Texas High School Principals" allowed principals to provide their perceptions of the roles and responsibilities for their present position as well as an ideal position. The final questionnaire, the four question "Survey of Job Satisfaction", assessed the level of job satisfaction for each principal. Hypothesis one was analyzed with a one-way ANOVA to determine if principals differed in their perceptions of their job roles and job positions. These positions included both the present job position and a more desired or ideal job position. The differences in these positions resulted in conflict. Hypothesis …

Differences in School Districts' Decision-Making Processes Before and After Tax Limitation Elections: A Case Study (open access)

Differences in School Districts' Decision-Making Processes Before and After Tax Limitation Elections: A Case Study

Using a case study approach, this investigation focused on the decision-making processes involved in developing budgets in two Texas school districts following a tax limitation, or rollback, election. Factors influencing the decision-making processes included the rollback election's outcome in each district, the participants, the perceptions participants held of themselves, the perceptions participants held of others in the district and community, the decisions made, and the factors influencing participants' decisions. Two Texas school districts were selected as subjects of this study which used qualitative data collection methods. In one school district, the rollback election passed. In the other, it failed. Data collection included observations of school board meetings and budget workshops. Structured interviews of school board members and administrators, pro- and antirollback proponents, and newspaper editors were conducted. Questions focused on the budgetary decision-making processes before and after the rollback elections. They also solicited information fromsubjects regarding rollback elections, the factors precipitating the rollback elections and the impact of the rollback election campaign upon each school district. Document analyses were triangulated with the observations and interviews to identify the factors influencing the budgetary decision-making process. Following the rollback elections, school officials in both districts adopted a conservative approach to budgetary decision-making. …

Academic Achievement of National Social Fraternity Pledges Compared to Non-Fraternity Students

This study examined the academic achievement of national social fraternity pledges compared to non-fraternity students at the University of Texas at Arlington. It was done to determine whether significant differences existed between the grade point averages of pledges of social fraternities and those of students who did not pledge a social fraternity, and to determine whether significant differences existed among fraternities when compared with each other with respect to academic achievement. This study was meant to provide a research design that could be used by other colleges and universities with fraternities to conduct the same comparison of academic performance. In the fall semester of 1989, 164 pledges were selected as the population for the study to be matched with non-fraternity students based on Scholastic Aptitude Test (SAT) scores, age, sex, classification, academic major, and number of hours attempted. A T-test of like groups was performed on the entire population with no significant difference found at the .05 level between all the fraternity pledges and all the matched pairs. A T-test of like groups was performed on the pledges from each separate organization and there was a significant difference among three of the fraternities. Two of the fraternities had significantly higher …

Learning Style and Leadership Style: Determinants of Instructional Strategies in Nursing Education (open access)

Learning Style and Leadership Style: Determinants of Instructional Strategies in Nursing Education

The problem of this study was to describe and compare the relationship of learning style and leadership style upon the selection of instructional strategies by nursing educators in associate and baccalaureate degree nursing programs. Data were collected using Kolb's Learning Style Inventory, Hersey and Blanchard's Leader Effectiveness and Adaptability Description, a researcher-developed Instructional Strategies Inventory, and the Personal Data Form. It was found that leadership style was highly correlated between the associate degree and baccalaureate degree faculty groups. More of the associate degree faculty members had basic leadership styles of Low Relationship/Low Task and High Task/Low Relationship. Most of the baccalaureate faculty members had Low Relationship/Low Task leadership styles. The following conclusions were developed: (a) Nursing faculty in associate and baccalaureate degree programs have similar learning and leadership styles; (b) nursing faculty tend to use the traditional instructional strategies such as lecture, discussion, and case studies at the same frequency of use? and (c) the selection of instructional strategies in nursing education may be affected by variables other than the instructor's learning and leadership styles. In view of the findings of this study, the following recommendations for further study appear to be warranted, (a) Further research should be conducted to …

The Influence of the First Amendment on Academic Freedom (open access)

The Influence of the First Amendment on Academic Freedom

Academic freedom has gone through three distinct eras yet each era overlaps a great deal with the one following it. The first era was the bureaucratic. It was exemplified by the negotiations between administrators and professors in the 1920s. The American Association of University Professors and the American Association of Colleges began cooperating and a hierarchical structure emerged, with the tenured professor at the top of the faculty. The second era was the political era and it was mainly a result of loyalty oaths, which began after the first World War and then escalated again during the 1930s when communism became a major concern. The political era then gave way to the legal era when the first academic freedom cases went to the United States Supreme Court in the 1950s. The first cases were the result of political pressures that became legal pressures. Most of the early court cases were based on communism. The legal era has produced changes. There are now more rights; for students and teachers of all levels, including pre-college levels, are guaranteed some academic freedom rights. However, the First Amendment and academic freedom are not synonymous because a professor usually cannot win a case based solely …

Development of Cooperative Education at the University of North Texas, 1976-1988

The main purpose of the study is to describe the developmental story of one of the larger university cooperative education programs in the United States to provide the evidence of outcomes and to utilize selected elements of the program in other colleges and universities. The study utilizes historical methodology with a descriptive approach to investigate and analyze the program's establishment, its development of staffing, organization, students, employers, funding, and its evaluation by using primary and secondary sources, annual reports, federal grant request proposals, evaluation reports, and the on-campus newspaper. The information for this study was also gathered through personal interviews with previous and present staff members of the program. The study shows that the program was established in the dean of students' office, but in order to get more support from the faculty, the program was moved to the academic affairs office. As a result of the academic support by the faculty, the program expanded. The findings show that the federal grant, Title VIII, contributed significantly to the initiation and growth of the program. The investigator observes that the director's leadership and the staff members' commitment to the program were two of the most important factors in the continued growth …

Academic, Behavioral, and Social Competency Characteristics of Non-Handicapped, Learning Disabled, and Emotionally/Behaviorally Disordered Adjudicated Juveniles (open access)

Academic, Behavioral, and Social Competency Characteristics of Non-Handicapped, Learning Disabled, and Emotionally/Behaviorally Disordered Adjudicated Juveniles

The juvenile justice system is society's response to juvenile misconduct. In spite of numerous federal, state, and local programs, the problem of juvenile delinquency persists. An increasing number of juveniles are being taken into custody and placed in institutional settings. Although juvenile delinquents share a number of common general characteristics (e.g., sex, minority, lower socioeconomic status, a history of school failure), they are not a homogeneous group. Effective educational interventions with delinquent juveniles can meet their unique academic, vocational, and social skills deficits. Handicapped juveniles are disproportionately represented among juvenile correctional facility populations. The identification of handicapped juveniles among delinquent populations is compounded as they share many of the same general characteristics. Federal statutes require individualized educational programs for all handicapped juveniles. This research investigated academic, behavioral, and social competencies of non-handicapped and handicapped adjudicated youth. Specifically, this investigation assessed measures of academic performance, classroom behavior, self-esteem, and social behavior. ANOVA indicated statistically significant differences between non-handicapped, learning disabled, and emotionally/behaviorally disordered adjudicated juveniles in reading achievement, mathematics achievement, and teacher generated measures of classroom behavior.

Teachers' Perceptions of their Enculturation Process

The purpose of this study was to construct portrayals of teachers7 work conceptions in various career stages from the stories they told and the metaphors they used to describe the ways in which teachers learned about their work. Specifically, the study included preservice teachers, first-year teachers, third-year teachers, and teachers with more than four years of teaching experience at the elementary and secondary school levels. Thirty-five elementary and secondary school teachers from the North-Central area of Texas participated in this study (nineteen inservice and sixteen preservice teachers). Qualitative techniques were employed to collect data. The preservice teachers filled out a questionnaire and wrote short stories about their preconceptions of their first year of teaching. Inservice teachers were interviewed using a short questionnaire and a long interview schedule. Nine inservice teachers participated in a storytelling workshop/focus group session. Group stories based on predetermined scenarios were constructed, tape-recorded and transcribed. The focus group session was videotaped and transcribed. Fifteen categories emerged from the analysis of the data: cyclical, ritualized, hierarchical, reciprocal, developmental, experiential, reflective, cumulative, body of knowledge, folkloric, individualized/personalized, order/control/manage, disciplinarian, facilitative, and replicative. These categories represent a summary of the constructs, images, contextual maps and metaphors held by these teachers …

A Study of the Relationship Between Selected Learning Styles and Achievement of Kindergarten Language Arts Objectives in a Local School District

The purpose of this study was to determine whether there is a relationship between the learning style of a kindergarten child and the level of achievement in language arts. The study was done at the request of the school district of a small community in north Texas, and it incorporated the total public school kindergarten population, 110 subjects. Instruments were the Learning Style Inventory: Primary by Perrin, the Iowa Tests of Basic Skills, and an achievement test developed by the regional education service center. The LSI:P was administered to all students by one person while the two achievement tests were administered by individual teachers to their own classes. The children were divided into groups according to their rating on the LSI:P, using the Prescription Circle by Dunn and Dunn as modifier. ANOVA and chi square analysis were utilized to compute frequencies and percentages at the .05 level to determine relationships between learning styles' group membership and attainment in language.

Adolescent Discouragement: Development of an Assessment Instrument (open access)

Adolescent Discouragement: Development of an Assessment Instrument

The Adolescent Discouragement Indicator (ADI) was developed to assess the Adlerian construct of discouragement. The 75-item ADI contains five subscales corresponding to the five life tasks specified in Individual Psychology and is specifically designed to pinpoint the area and degree of adolescent discouragement. Item selection was based on ratings by five prominent Adlerians and item correlation with subscale scores. Age and sex norms for the ADI were established on 225 females and 299 males 12 to 18 years of age. Findings indicate that female adolescents are less discouraged than male adolescents on all scales except the love scale and both sexes reported the least amount of discouragment on the love scale. The only significant difference among the age groups is between the 13-year-olds and the 15, 16, and 17-year-olds on the love scale. An internal consistency coefficient of .95, a 2-week test-retest coefficient of .89, and a 4-week test-retest coefficient of .92 indicates that the ADI is a reliable instrument. Negative and significant (p < .001) correlations between the ADI and Social Interest Index (Greever, Tseng, & Friedland, 1973) and between the ADI and the Social Interest Scale (Crandall, 1975) contribute to construct validity and support Adler's belief that discouragement …

The primary purpose of the study was to develop an expert system that could C D perform medical diagnoses In selected problem areas, and C2) provide diagnostic Insights to assist medical students In their training. An expert system Is a computer-based set of procedures and algorithms that can solve problems In a given domain. Two research questions were proposed. The first was "Given a problem space defined by a matrix of diseases and symptoms, can a computer-based model be derived that will consistently perform accurate and efficient diagnoses of cases within that problem area?" The second question was "If the techniques derived from the model are taught to a medical student, is there a subsequent improvement of diagnostic skill?" An expert system was developed which met the objectives of the study. It was able to diagnose cases in the two problem areas studied with an accuracy of 94-95%. Furthermore, it was able to perform those diagnoses in a very efficient manner, often using no more than the theoretical minimum number of steps.

A State-Wide Survey on the Utilization of Instructional Technology by Public School Districts in Texas

Effective utilization of instructional technology can provide a valuable method for the delivery of a school program, and enable a teacher to individualize according to student needs. Implementation of such a program is costly and requires careful planning and adequate staff development for school personnel. This study examined the degree of commitment by Texas school districts to the use of the latest technologies in their efforts to revolutionize education. Quantitative data were collected by using a survey that included five informational areas: (1) school district background, (2) funding for budget, (3) staff, (4) technology hardware, and (5) staff development. The study included 137 school districts representing the 5 University Interscholastic League (UIL) classifications (A through AAAAA). The survey was mailed to the school superintendents requesting that the persons most familiar with instructional technology be responsible for completing the questionnaires. Analysis of data examined the relationship between UIL classification and the amount of money expended on instructional technology. Correlation coefficients were determined between teachers receiving training in the use of technology and total personnel assigned to technology positions. Coefficients were calculated between a district providing a plan fortechnology and employment of a coordinator for instructional technology. Significance was established at the …
