Filial Therapy Training with Undergraduate Teacher Trainees; Child-Teacher Relationship Training

This experimental research study investigated the effectiveness of the application of Child-Teacher Relationship training, adapted from child-centered play therapy procedures and skills training (filial therapy), with undergraduate teacher trainees. Specifically, this research determined if Child-Teacher Relationship training facilitated change in teacher trainees' interactions with children, parenting attitudes, and play therapy attitude knowledge and skills. The experimental group of teacher trainees (n=18) received 10 weekly ninety minute training sessions in child-centered play therapy skills and procedures and conducted 7 weekly special play times with children. The comparison group (n=20) received supplemental training in child guidance during the ten weeks that included parent training and alternatives to corporal punishment. Experimental and comparison group participants completed pre-test and post-test measures, consisting of the Adolescent and Adult Parenting Attitudes Inventory (AAPI-2), the Play Therapy Attitudes, Knowledge, and Skills Survey (PTAKSS), and a videotaped special play time with a child which was rated using the Measurement of Empathy in Adult and Child Interactions (MEACI). Analysis of covariance on adjusted post test means revealed that the teacher trainees in the experimental group demonstrated statistically significant ("<.05) increases in empathy towards children, allowing the child self direction, communication of acceptance, and involvement as measured by the MEACI. …

A Comparison Study of Individual and Group Play Therapy In Treating Kindergarten Children with Adjustment Problems (open access)

A Comparison Study of Individual and Group Play Therapy In Treating Kindergarten Children with Adjustment Problems

This study was designed to determine the effectiveness of individual child-centered play therapy in the elementary school in: 1) enhancing the self-concept of kindergarten children who are experiencing adjustment difficulties; 2) decreasing the overall behavioral problems of kindergarten children experiencing adjustment difficulties 3) decreasing externalizing behavior problems such as aggression and delinquency of kindergarten children experiencing adjustment difficulties; 4) decreasing the internalizing behavior problems such as withdrawal, somatic complaints, anxiety and depression of kindergarten children experiencing adjustment difficulties; 5) increasing parental perception of change in the problematic behaviors of kindergarten children experiencing adjustment difficulties; and 6) enhancing self-control in kindergarten children experiencing adjustment difficulties. A secondary objective was to compare the participants involved in individual child-centered play therapy with participants in a previous study who were involved in child-centered group play therapy on the above named dimensions. The experimental group, consisting of 14 kindergarten children experiencing adjustment difficulties, received 10-12, 30-minute individual play therapy sessions in a 12 week period in their elementary school. The comparison group, utilized from the 1999 McGuire study, consisted of 15 children with adjustment problems and received 12-14, 45-minute group play therapy sessions in 14 weeks in their elementary school.

A survey of mentor/mentee activities in beginning teacher induction programs in Region XI (open access)

A survey of mentor/mentee activities in beginning teacher induction programs in Region XI

The recruitment and retention of teachers demand attention with estimates of two million new teachers needed in the next decade. Hiring under qualified teachers necessitates adequate induction programs. Development of a recommendation for a teacher induction program comprises the purpose of the study. The recommended induction and support program addresses the activities perceived as valuable by both mentors and mentees. The researcher describes the mentor programs currently in place in Region XI in northern Texas by surveying the mentors and mentees; of particular relevance is a determination and description of the program model in place. Data sources include the literature review and information obtained from Region XI mentors/mentees. Data shows the model in Region XI is primarily a colleague model. Mentors and mentees are matched for grade level, content area and physical proximity. Three of the most frequently occurring activities are in the category emotional support, three in logistical concerns, two in systems information, one in student management, and one in instructional support. Mentees believe those activities associated with classroom management and organization and developing confidence and self-esteem are most important. Mentors concur. Specific recommendations for structuring a comprehensive beginning teacher induction and support program include reexamining the program currently …

Accent and Grouping Structures in the String Quartets of Béla Bartók (open access)

Accent and Grouping Structures in the String Quartets of Béla Bartók

The music of Béla Bartók is defined in part by its unique blend of rhythmic vitality and inventiveness, and his string quartets offer a glimpse into a consistency of technique evident throughout his compositional career. Bartók's rhythmic environments are primarily metrical, but many of his rhythmic configurations are placed in such a way as to potentially override established meter. It is necessary, therefore, to institute an analytical means by which the delineation and comparison of rhythmic structures both within and without the metrical context may be accomplished. An analytical method using Timepoint Accent Structures (TAS) allows for the comparison of rhythms resulting from patterns of accent produced by pitch onset, dynamic stress, articulation or any other accentual factors. Timepoint Grouping Structures (TGS) delineate the number of timepoints present in alternating groups/blocks in a texture, thereby allowing for the recognition of patterning created by these larger groups. By applying TAS and TGS analysis, relationships of rhythmic equivalency, rotation, retrograde, complementation, augmentation, diminution, subset, superset, exchange, compression and expansion are clearly confirmed in the string quartets. In addition, symmetrical structures and arithmetic progressions are discovered. In many ways, Bartók's rhythmic organization mimics his procedures of pitch structuring.

Factors that influence teacher turnover in Texas: Correlations with variables from the academic excellence indicator system for the year 1998-99 (open access)

Factors that influence teacher turnover in Texas: Correlations with variables from the academic excellence indicator system for the year 1998-99

The teacher shortage problem is a national and state concern. In 1998, the Texas State Board of Education Certification reported that school districts in Texas had to hire teachers to fill over 63,000 vacancies. Teacher resignations, other than retirement, contributed to over 46,000 teachers who left the profession about 19 % of the state's total teacher workforce. A significant number of Texas teachers left the profession in the first five years. The National Commission on Teaching and America's Future (1996) called the attrition of new teachers a chronic problem for American schools. Reducing the teacher shortage in Texas must begin with reducing the teacher turnover rate. Most studies concerning teacher attrition or turnover either address salary, or working conditions. Many of the studies deal with affective and subjective data regarding teacher turnover. The studies on teacher turnover often do not address quantifiable data collected uniformly across districts. Few studies address a comprehensive set of quantitative data to determine the variables associated with teacher turnover. This study addressed teacher turnover through quantitative research of data from the Texas Academic Excellence Indicator System (AEIS) with multiple analysis to provide insights to teacher turnover conditions and trends. The population for the study included …

A Comparative Analysis of the Effectiveness of Three Different GED Preparation Programs (open access)

A Comparative Analysis of the Effectiveness of Three Different GED Preparation Programs

The purpose of this study was to identify effective instructional programs for GED tests preparation for students in a large suburban school district. Three different nonrandom, unequal naturally occurring instructional groups at three different locations were examined. One group participated in a traditional instruction program, a second group in a test/retest program, and a third group in a computer-assisted program. The demographics of the district population, the GED population, and the individual study groups were catalogued and analyzed. The demographics of the GED population were similar to the district population but different from the GED passers. Student characteristics did affect GED success. Both quantitative and qualitative data were gathered. Random students in each of the three groups were interviewed about their experiences in GED preparation using a questionnaire. Quantitative data were analyzed using frequencies, means, correlations, and a multiple regression analysis. Since the GED credential is an alternative to the high school diploma, its use as a dropout alternative is important to every school district. The study found that instructional methods had little impact on students' success in receiving the GED credential. The overall success rate of students was low in each group. The student's reading achievement score, GPA, and …

istance-Mediated Christian Higher Education: Student Perceptions of the Facilitative Nature of Selected Instructional Development Factors

A national survey was conducted to assess student perceptions of the helpfulness of specific instructional development factors in a distance education print-based program. Participants were all students who had successfully completed at least one distance education correspondence course with Global University or were currently enrolled in their first course. Instructional development factors studied included lesson openers, lesson outlines, lesson artwork, written objectives, amount of information presented before a study question is asked, typographical features, graphic art, study questions, answers to study questions, self tests, and unit progress evaluations. Basic demographic information was collected and survey respondents located their perceptions of instructional development factor helpfulness both on a Likert scale and on a rank-order scale. Respondents also were asked for comments on the instructional development factors studied. Differences among respondent groups were examined. Major findings include a tiered ranking by all groups showing formative evaluation factors to be the most helpful, content organization and presentation factors next most helpful, and visual enhancement features (graphic art, typographical design) the least helpful. Overall, perceptions of the facilitative nature of the instructional development factors were similar among most groups. Older students seem to focus more on organization while younger students exhibit a balance between …

Parent, Student, and Faculty Satisfaction With and Support of Campus Laboratory School Programs

The primary purpose of the study was to investigate stakeholders' opinions concerning campus laboratory school program quality in three areas: (1) quality of teacher education, (2) research, and (3) childcare. There were 653 participants in the study: 246 parents whose children were enrolled in laboratory schools, 200 pre-service students who were taking early childhood or child development classes, and 207 faculty who were associated with campus laboratory schools. The study participants came from 122 campus children centers in the United States. These campus centers were members of either the National Coalition for Campus Children's Centers (NCCCC) or the National Organization of Laboratory Schools (NOLS). The first three research questions investigated whether parents, students, and faculty were satisfied with program quality. A one-way analysis of variance indicated a statistically significant mean difference between the three groups. The parents had a higher mean level of program quality satisfaction than students and faculty. The last three research questions investigated whether parents, students, and faculty supported the ongoing existence of campus laboratory school programs. Opinions were scaled from 1=not ever to 5=definitely. The overall mean ratings for Parents (4.54), students (4.18), and faculty (4.07) indicated that they supported the ongoing existence of campus laboratory …

Computer Supported Collaboration: Is the Transfer of Cognitive Structures Mediated by Mode of Communication?

The objective of this study was to observe evidence of structural transfer among subjects in a group problem-solving activity and determine whether mode of collaborative technology or use of a priming agent affected the nature of transferred structures. Evidence for structural transfer is found in three theoretical perspectives: organizational ditransitive (linguistic) verb structures, adaptive structuration theory, and mental model transfer theory. Dependent variables included various grammatical structures and coefficients derived from pretest and posttest scores on David Kolb's Learning Styles Inventory, modified for the experiment. The combination of changes in grammatical frequencies and learning style may suggest that one or more media or the priming agent may affect structural transfer. Results indicate that groups using the GroupSystems™ collaborative technology produced less overall linguistic content than did subjects using a generic chat system, but employed more complex language as indicated by frequency of the organizational ditransitive verb structure. Also, subjects supplied with an organization chart (priming agent) during the group problem-solving session experienced greater change on the learning styles inventory than did those participating in the session without the chart. These findings suggest that mode of communication and use of priming agents may contribute positively or negatively to the transfer of …

Mentoring the first-year superintendent in Texas public schools. (open access)

Mentoring the first-year superintendent in Texas public schools.

This study determined what mentoring experiences first-year superintendents have had and what they need from a mentoring relationship. Structured interviews and field notes were used in this qualitative study focused on Texas first-year superintendents' perceived needs from mentors. Three patterns of mentoring relationships were found: 1) no mentor in the first year, 2) mentor-protégé relationship - those who developed mentoring relationships early in a career with a more senior person in the same school system, and 3) mentoring relationships of convenience - young relationships which developed outside the same system. Skills and knowledge areas novice superintendents identified as critical for mentor assistance were school finance, development of effective relationships with groups that have expectations of the superintendent while also improving student achievement, and working within the politics of the position. Mentor characteristics novice superintendents considered necessary for a positive effect on job success include: trustworthiness, confidentiality, empathy, encouraging, active listening, and integrity. An attitude in which the mentor problem solved with the protégé, and did not give an immediate solution was displayed. Mentors actively and frequently initiated contact. Ideas were freely exchanged, giving the protégé undivided attention while not making the protégé feel inferior. The effects that previous mentoring experiences …

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities (open access)

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities

The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions. (open access)

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.

The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests …

Student preferences in screen design factors for Internet delivered college courses. (open access)

Student preferences in screen design factors for Internet delivered college courses.

Colleges and universities throughout the world are offering many of their courses via the Internet. Some institutions offer entire degrees online. This has ushered in a renewed interest in the debate on the effectiveness of non-traditional course delivery method. Numerous educational research studies have been conducted in an attempt to quantify that effectiveness. In any form of experimental research, control of variables is paramount. The rich multimedia capabilities of the World Wide Web give educators a wide variety of delivery media. However, with the exception of advice from artisans on design factors of the media, little research has been conducted with regard to the aesthetics of Web page design as viewed by the student. This study was conducted in an effort to establish student preferences with regard to two factors of Web page design as they might be used on those Web pages, background color and typeface used for text. In addition, it contains an analysis of whether or not there is an interaction between the two factors. Use of the results of this study should prove beneficial to both educators and educational researchers in their future endeavors.

Candidates' Perception of Training and Self-Efficacy in Traditional and Alternative Teacher Preparation Programs. (open access)

Candidates' Perception of Training and Self-Efficacy in Traditional and Alternative Teacher Preparation Programs.

This research was encouraged by the tremendous demand for teachers. Two million new teachers will be needed in the United States over the next decade. The teacher shortage has school administration, school boards, education agencies, and institutions of higher education investigating how to train and retain more teachers. Alternative certification programs have been developed to address the teacher shortage. This study examined the effectiveness of traditionally and alternatively certified teachers in two separate programs with regard to their self-efficacy, perception of their training, and their ExCET scores. Traditional candidates (10) and alternative candidates (74) were examined using survey research. According to this data on self-efficacy, perception of training, and ExCET passing rates, there is no significant difference between those teachers who receive traditional training and those who are trained in alternative certification programs.

Constructing Transformative Experiences Through Problem Posing in a High School English Research Project.

This dissertation chronicles my search to engage high school English students in inquiry as part of a formal research process. The perspective of critical literacy theory is used to describe the four phases of the problem posing process in shaping student research and action. Grounded in Freire's approach and consistent with Dewey and others who advocate inquiry, action and relevance, Wink's process is built into the instructional plan described in this study. Because of the real-life context of the classroom and the complex social phenomena being considered, a case study methodology was utilized in which multiple sources of data converged to develop the themes. Data sources included the work and artifacts of ten students in a tenth grade English class during the spring semester of 2008. The analysis focuses on the supports, the constraints and the impact of problem posing on the high school research assignment. The analysis, findings, and conclusions contribute to the literature in three areas: audience, reflection and grading.

Metro Environmental: The impact of training HVAC technicians using the SightPros-VirTechs system for remote, wireless, Internet video assistance.

This qualitative study explored the overall impact of training HVAC technicians using the SightPros-VirTechs system for remote, wireless, internet video assistance at a small HVAC company, Metro Environmental. John Thomason, the president/co-owner developed a website and a new SightPros communication tool that allows wireless, one-on-one, just-in-time, high-quality, video-monitored instructions between an expert at one site and a technician at another site. Metro Environmental successfully used the SightPros-VirTechs system to train a new apprentice remotely. The apprentice and expert changed their normal and routine physical activities because the expert worked remotely and the apprentice worked on-site. Within just a few months, the apprentice proved competent enough to go to customer accounts without more experienced technicians nearby. The technicians express excitement about the SightPros communication tool as a way to contact remote experts whenever needed. The customer and business contacts also give good reviews and suggest other benefits. The expert permanently captures the communications so the company can use the saved video for many applications, especially training. The dissertation provides a list of recommendations to trainers/educators for similar applications.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement. (open access)

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.
