The Effectiveness of a Mediating Structure for Writing Analysis Level Test Items From Text Based Instruction

Description: This study is concerned with the effect of placing text into a mediated structure form upon the generation of test items for analysis level domain referenced test construction. The item writing methodology used is the linguistic (operationally defined) item writing technology developed by Bormuth, Finn, Roid, Haladyna and others. This item writing methodology is compared to 1) the intuitive method based on Bloom's definition of analysis level test questions and 2) the intuitive with keywords identified method of item writing. A mediated structure was developed by coordinating or subordinating sentences in an essay by following five simple grammatical rules. Three test writers each composed a ten-item test using each of the three methodologies based on a common essay. Tests were administered to 102 Composition 1 community college students. Students were asked to read the essay and complete one test form. Test forms by writer and method were randomly delivered. Analysis of variance showed no significant differences among either methods or writers. Item analysis showed no method of item writing resulting in items of consistent difficulty among test item writers. While the results of this study show no significant difference from the intuitive, traditional methods of item writing, analysis level test item generation using a mediating structure may yet prove useful to the classroom teacher with access to a computer. All three test writers agree that test items were easier to write using the generative rules and mediated structure. Also, some relief was felt by the writers in that the method theoretically assured that an analysis level item was written.

Effectiveness of a Performance Contracting Program in Reading and Mathematics Relative to Educationally Deprived Secondary School Students

Description: This study has two purposes. The first is to compare the academic skills achievement in reading and mathematics of students participating in a performance contracting program with the academic skills achievement of students not participating in the performance-based program. The second is to determine whether those students participating in the performance contracting program show a significantly different level of achievement (higher or lower) than the control group approximately four months after the conclusion of the program.

The Effectiveness of a Professional Learning Community on Student Achievement in Elementary Reading and Mathematics in a Large Urban School District

Description: The study was to determine the impact of a Professional Learning Community on student achievement as measured by the state's criterion referenced reading and mathematics achievement tests. Data for this study were extracted from the school district's student database. Two cohorts of 90 students each were randomly selected from a population of approximately 600 students in 3 schools that participated in a Professional Learning Community (treatment) and 3 schools that did not (control). Professional Learning Communities known as PLCs, can serve as a major theoretical framework to promote the improvement of classroom teachers' instructional practice, teacher effectiveness and student achievement. Reading and mathemtics mean scale scores were extracted at three time points (year 1, year 2, and year 3) across three grades (grade 3, grade 4 and grade 5). Test for equality of variance found that no statistically significant difference existed between the mean scale scores of the two cohorts at the beginning of the study. The findings revealed that both cohorts trend toward increased academic achievement from year to year individually; however, when compared to each other, no statistically significant difference existed. Further research is indicated to examine each PLC for implementation, support and leadership as they relate to the PLC and a focus on instruction and learning.

The Effectiveness of a Stress Reduction Program for Police Officers

Description: A group of veteran police officers was studied in relation to the effectiveness of a stress reduction program which utilized a cognitive-behavioral approachto training. A new instrument, the Coulson Police Job Stress Discussionaire, (CPJSD), was field tested. Two control groups, a veteran group who received no stress reduction training and an academy group which received standard basic training but not the stress reduction program, were compared on pre—test and post-test Profile of Mood States (POMS) mood disturbance cores. Contrary to the main hypothesis formulated, there were no significant differences found between the three groups on post-test POMS measures of mood disturbance when compared with pre-test measures. The construct validity of the POMS for use with police officers is challenged. The specific format utilized is discussed and suggestions are offered for future study design. Specific difficulties inherent in the study of police groups are examined. The usefulness of the CPJSD for police job stress reduction program is suggested, as is the need for further field testing of this instrument.

Effectiveness of a Transitional First Grade Program

Description: The purpose of this study was to determine the effectiveness of a transitional first grade program. A comparison of reading and math achievement and school attitude was the focus of the study. The study utilized a pretest/posttest design. The group of regular first grade students who qualified for the transitional program but attended regular first grade was the control group. The group of transitional first grade students was the experimental group. The regular first grade students received formal instruction in all academic areas. The experimental group received no formal instruction. All students were pretested and posttested using the Iowa Test of Basic Skills and the Minnesota School Attitude Survey. Testing was administered to small groups of five or less by the researcher. Scoring was done also by the researcher. An analysis of covariance was used to determine if a significant difference existed between the groups. The analysis of covariance did not produce a significant F at the .05 level when applied to the Iowa Test of Basic Skills except for reading for boys in both groups. The numbers in each cell were low and no further comparisons were made. Due to a testing date that was approved late in the year, the Minnesota School Attitude Survey was determined to be invalid. Scores are reported for the reader's perusal only.

Effectiveness of a Web-based Course in Facilitating the Integration of Technology Into Early Childhood Curricula.

Description: Although technology is available and used in early childhood classrooms, little is known about what early childhood teachers believe about the use of technology and how technology is integrated into early childhood curricula. This study was designed to (a) determine the beliefs of early childhood teachers about technology integration into early childhood curricula and (b) describe the extent to which early childhood teachers integrate technology in their early childhood curricula. The participants included 39 prekindergarten teachers who volunteered to participate in a technology integration project. The treatment group accessed a Web-based technology integration training program and participated in two classroom observations, along with completing an attitudinal questionnaire pretest and posttest. The Prekindergarten Web-based Technology Integration Training included four modules each expanding the following themes: (a) national and state standards and guidelines for technology; (b) setting up a computer center; (c) integrating technology; (d) using the digital camera. The control group participated in two classroom observations without the benefit of the Web-based technology integration training program and completed the attitudinal questionnaire pretest and posttest. Results indicate that Prekindergarten teachers believe that technology can enhance a child's learning, but there was no statistically significant difference between the control and the treatment group.

The Effectiveness of an Electronic-Mail Campaign to Modify Stress Levels, Mood States, and Coping Techniques Among Employed Adults

Description: The present study was conducted to explore the effectiveness of a worksite stress management program delivered via electronic mail (e-mail). One hundred and thirty-seven employed adults (36 males, 102 females; mean age = 29.46) from several diverse businesses consented to participate. The volunteers completed Cohen's Perceived Stress Scale, the Daily Hassles Scale, the Daily Work Hassles Scale, the TCU Self-Ratings Scales, and a demographic and opinion questionnaire. Individuals in the treatment group received e-mail messages twice weekly and had access to a website for three months about a variety of cognitive-behavioral techniques for managing worksite stress. A MANCOVA of post-intervention stress levels indicated that individuals who received the stress management messages perceived the same amount of stressors and hassles as individuals who did not receive the messages [F (5, 86) = 0.95, p = .45]. However, a MANCOVA of post-intervention perceived mood states revealed a tendency for individuals in the treatment group to be less depressed, anxious, and angry than individuals in the control group [F (3, 92) = 2.44, p = .07]. Demographic variables did not influence the outcome variables and pre- and post-test absenteeism and illness rates were similar for treatment and control groups. Coping skill usage was similar in amount and frequency, but differed in quality between the groups. The findings of the present study indicate that health promotion programs can be feasibly and effectively delivered via e-mail in the worksite.

The Effectiveness of an Infant Simulator as a Deterrent to Teen Pregnancy Among Middle School Students

Description: This research was one of the first longitudinal studies to determine the effectiveness of a computerized infant simulator as a deterrent to adolescent pregnancy. All of the female eighth-grade students (221) in 1994-1995 and 1995-1996 from a suburban North Texas middle school were part of this study. They were tracked from the eighth grade through high school graduation to determine whether and when pregnancies occurred. The Kaplan-Meier procedure for survival analysis was used to determine test statistics. Survival functions and hazard functions were created for each independent variable--parenting the infant simulator, ethnic and racial, involvement in co-curricular activities, and crime. Results showed the computerized infant simulator to be highly effective in postponing the on-set of pregnancies for those students who participated in the parenting simulation. Hazards peaked at 3 years, 2 months for the experimental group and at 2 years, 21/2 months for the control group. Summertime and holiday seasons marked times of the year when the majority of pregnancies occurred. Caucasians peaked before the Other ethnic group. No significant differences were detected in regard to involvement in co-curricular activities, and no involvement in crime was self-reported. The model was developed to use as a guideline for implementing a pregnancy prevention unit in schools. This model could be used by Family and Consumer Sciences classes, teen pregnancy prevention programs, childbirth preparation classes, at-risk student programs, substance abuse intervention programs, and religious education classes.

The Effectiveness of Business Leadership Practices among Principals on Student Achievement on Public School Campuses in Texas

Description: The purpose of this descriptive study was to determine if business leadership practices by Texas public school principals have an impact on principals' campus student achievement in mathematics and reading, as measured by TAKS scores. The survey instrument was the Leadership Assessment Instrument (LAI), developed by Warren Bennis in 1989. The survey instrument was electronically distributed to a sample of 300 public school principals in Texas. Of the 300, 140 principals completed and returned the survey, for a response rate of 47%. The Statistical Package for the Social Sciences (SPSS), version 16.0, was used for the analysis of data, which included descriptive statistics, analysis of variance, and regression. In addition, reliability for the LAI was also calculated. The LAI consists of the following five categories of effective business practices: focused drive, emotional intelligence, building trust, conceptual thinking, and systems thinking. No significant relationships were found between principals' use of LAI elements and student achievement in mathematics and reading. However, the lack of significant relationships between the business model as used in public schools and student achievement reveals that current models of principal preparation programs do not result in school leaders who are adequately prepared to increase student achievement. Further research is recommended as public school leaders continue to seek alternative strategies and innovative practices to improve student achievement.

Effectiveness of Child-centered Play Therapy and Person-centered Teacher Consultation on ADHD Behavioral Problems of Elementary School Children: a Single Case Design.

Description: I examined the effectiveness of child-centered play therapy (CCPT) and person-centered teacher consultation (PCTC) for elementary school children identified with clinical or borderline levels of ADHD behaviors on the Teacher Report Form and the Conners' Teacher Rating Scale Revised - Short Form. Additionally, I examined the impact of CCPT and PCTC on the levels of parenting and teaching stress. Due to the current trend to determine interventions that are evidence-based through between-group or single case designs, for this study, I utilized a single case design experiment for which the behaviors of five children were examined. Trained observers utilized the Direct Observation Form in observations of all five students three times per week. Additionally, parents and teachers completed behavioral rating scales and stress inventories at pre-, mid-, and post-intervention. To prevent biased observational ratings, observers were blind to the assignment of the five children. Three students participated in 24 sessions of twice-weekly 30-minute sessions of CCPT, and these students' teachers participated in six sessions of once-weekly 10-minute PCTC. Two students participated in twice-weekly 30-minute sessions of reading mentoring, after which they participated in 14 sessions of CCPT. Visual analysis of the data indicated mixed results. Three students demonstrated substantial improvement in the observed ADHD behaviors within the classroom. Results of the parent and teacher assessment data were inconsistent, but did indicate behavior change for some children and a reduction in teaching stress for one teacher. Parenting stress appeared unaffected. Implications for future research regarding the use of single case design, the measurement of student behavior change, and issues of comorbidity are indicated.

Effectiveness of Child-Centered Play Therapy with Japanese Children in the United States

Description: This study explored the use of child-centered play therapy (CCPT) as a culturally responsive intervention and a prevention treatment method for the psychosocial well-being of Japanese children in the United States. In light of the demand for the evidence-based therapeutic treatment for children as well as the need to conduct multicultural research without ignoring within-group differences, this study was composed of two research methodologies; quantitative research design and individual analysis. Single-group repeated measures ANOVA was utilized for the group analysis and linear regression was employed for individual analysis in addition to qualitative data obtained through parent feedback and the researcher's observation of play therapy sessions. The participating children received a total of eight CCPT sessions. The impact of CCPT was measured by a decrease in a child's behavioral problems perceived by a parent measured by scores of the Internalizing Problems, Externalizing Problems and Total Problems on the Child Behavioral Checklist and a reduction of parent-child relationship stress manifested in the Child Domain, Parent Domain and Total Stress Score of the Parenting Stress Index. Data from a total of the four assessment points; the baseline, pretest, second assessment, and third assessment, was gathered for use in the analysis. A total of 16 children were recruited from the Japanese School of Dallas for participation in this study. However, some children did not complete the entire set of 8 play therapy sessions, and as a consequence, neither were all assessments completed by their parents. Therefore, data from 10 children, age ranging from 4 to 9, were utilized for the statistical analysis. The results of the analysis did not reveal any statistical significance. However, large and medium effect sizes were obtained on all the six aforementioned subscales during the treatment period. Individual analysis provided further information on possible environmental, developmental, and cultural factors that ...

The Effectiveness of Denton State School's Developmental Evaluation Form in Evaluating an Operant Training Program for Severely Retarded Boys

Description: The problem of this study was to evaluate Denton State School's Developmental Evaluation Form as it is now being used in their operant conditioning techniques in certain basic self-help areas, and to suggest a more effective and informative method of scoring the Evaluation Form. The present method of scoring this evaluation form requires that -all items at each developmental level be passed in order to receive credit for that level. No partial credit is given at any level. This method of scoring yields a developmental level at which. the individual is functioning. It does not, however, point out the total overall development of the individual. The present type of basal developmental scoring is not as discriminating as far as picturing an individual's total development as the one which will be suggested.

Effectiveness of Filial/Play Therapy Training on High School Students' Empathic Behavior with Young Children

Description: This study was designed to determine the effectiveness of a filial/play therapy training model with high school juniors and seniors enrolled in a Peer Assistance and Leadership program (PALs). Filial/play therapy is an intervention that focuses on strengthening and enhancing adult-child relationships. The high students are trained to be a therapeutic change agent for primary school children identified as having adjustment difficulties by utilizing basic child-centered play therapy skills in weekly play sessions with young children. Specifically, this study is designed to determine the effectiveness of filial therapy in increasing: 1) the high school students' observed empathic behavior with young children, 2) the high school students' observed attitude of acceptance toward young children, 3) the high school students' observed ability to allow self-direction in young children, and 4) the high school students' observed level of involvement with young children. The experimental group, consisting of 16 volunteer high school students enrolled in a PALs class for high school credit, received a total of 24 weeks of filial/play therapy didactic training, application, and supervision for the playtimes they conducted with pre-kindergarten/kindergarten students identified with adjustment difficulties. The comparison group consisted of 15 volunteer high school students enrolled in a PALs class for high school credit. The comparison group received the standard PALs class curriculum. All students were videotaped playing with a young child 4 to 6 years of age before and after the training as a means of measuring empathic behavior with young children. An Analysis of Covariance revealed statistically significant findings in all four hypotheses. Specifically, the experimental group of high school students exhibited statistically significant increases in empathic interactions with young children when compared to the comparison group. The experimental group also exhibited statistically significant increases in communication of acceptance of young children's feelings and behaviors, acceptance and behavioral willingness ...

Effectiveness of Fillers for Corrosion Protection of AISI-SAE 1018 Steel in Sea Salt Solution

Description: Corrosion represents the single most frequent cause for product replacement or loss of product functionality with a 5% coat to the industrial revenue generation of any country in this dissertation the efficacy of using filled coatings as a protection coating are investigated. Fillers disrupt the polymer-substrate coating interfacial area and lead to poor adhesion. Conflicting benefits of increasing surface hardness and corrosion with long term durability through loss of adhesion to the substrate are investigated. The effects of filler type, filler concentration and exposure to harsh environments such as supercritical carbon dioxide on salt water corrosion are systematically investigated. The constants maintained in the design of experiments were the substrate, AISI-SAE 1018 steel substrate, and the corrosive fluid synthetic sea salt solution (4.2 wt%) and the polymer, Bismaleimide (BMI). Adhesion strength through pull-off, lap shear and shear peel tests were determined. Corrosion using Tafel plots and electrochemical impedance spectroscopy was conducted. Vickers hardness was used to determine mechanical strength of the coatings. SEM and optical microscopy were used to examine dispersion and coating integrity. A comparison of fillers such as alumina, silica, hexagonal boron nitride, and organophilic montmorillonite clay (OMMT) at different concentrations revealed OMMT to be most effective with the least decrease in adhesion from filler-substrate contact. Subsequently examining filler concentration, a 3 wt% OMMT was found to be most effective. A comparison of unmodified and modified BMI with 3 wt% OMMT exposed and not exposed to supercritical carbon dioxide showed that the BMI provided better corrosion protection; however, OMMT provided better wear, shear, and hardness performance.
