Reactions and learning as predictors of job performance in a United States Air Force technical training program

Reactions and learning as predictors of job performance in a United States Air Force technical training program

Date: December 1999
Creator: Boyd, Steven W.
Description: This study is based on Kirkpatrick's (1996) four level evaluation model. The study assessed the correlation between and among three levels of data that resulted from evaluation processes used in the U.S. Air Force technical training. The three levels of evaluation included trainee reaction (Level 1), test scores (Level 2), and job performance (Level 3). Level 1 data was obtained from the results of a 20 item survey that employed a 5-point Likert scale rating. Written test scores were used for Level 2 data. The Level 3 data was collected from supervisors of new graduates using a 5-point Likert scale survey. The study was conducted on an existing database of Air Force technical training graduates. The subjects were trainees that graduated since the process of collecting and storing Levels 1 and 2 data in computerized database began. All subjects for this study graduated between March 1997 and January 1999. A total of 188 graduates from five Air Force specialties were included. Thirty-four cases were from a single course in the aircrew protection specialty area; 12 were from a single course in the munitions and weapons specialty area; and 142 were from three separate courses in the manned aerospace maintenance specialty ...

Bias and Precision of the Squared Canonical Correlation Coefficient under Nonnormal Data Conditions

Bias and Precision of the Squared Canonical Correlation Coefficient under Nonnormal Data Conditions

Date: August 2006
Creator: Leach, Lesley Ann Freeny
Description: This dissertation: (a) investigated the degree to which the squared canonical correlation coefficient is biased in multivariate nonnormal distributions and (b) identified formulae that adjust the squared canonical correlation coefficient (Rc2) such that it most closely approximates the true population effect under normal and nonnormal data conditions. Five conditions were manipulated in a fully-crossed design to determine the degree of bias associated with Rc2: distribution shape, variable sets, sample size to variable ratios, and within- and between-set correlations. Very few of the condition combinations produced acceptable amounts of bias in Rc2, but those that did were all found with first function results. The sample size to variable ratio (n:v)was determined to have the greatest impact on the bias associated with the Rc2 for the first, second, and third functions. The variable set condition also affected the accuracy of Rc2, but for the second and third functions only. The kurtosis levels of the marginal distributions (b2), and the between- and within-set correlations demonstrated little or no impact on the bias associated with Rc2. Therefore, it is recommended that researchers use n:v ratios of at least 10:1 in canonical analyses, although greater n:v ratios have the potential to produce even less bias. ...

Computer supported collaboration: Is the transfer of cognitive structures mediated by mode of communication?

Computer supported collaboration: Is the transfer of cognitive structures mediated by mode of communication?

Date: May 2002
Creator: Bandy, Kenneth E.
Description: 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 ...

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

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

Date: May 2003
Creator: Alexander, Erika D.
Description: 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.

A comparative analysis of traditional versus block and accelerated block scheduled high schools over an eight-year period in a large urban school district

A comparative analysis of traditional versus block and accelerated block scheduled high schools over an eight-year period in a large urban school district

Date: August 2001
Creator: McCumber, Patricia Morrison
Description: This study compared traditional, A/B and accelerated block scheduling and its effects on student achievement and attendance by comparing the differences in student outcomes observed before and after the adoption of block/accelerated block schedules. The independent variable was the use of time in a block-scheduling model. The dependent variables were student outcomes measured by nine indicators based on the Academic Excellence Indicator System in Texas: student attendance, graduation rate, dropout rate, percentage of students taking advanced courses, percentage of students passing all Exit-level Texas Assessment of Academic Skills tests, percentage of students taking College Admissions Tests, mean SAT total score of those students who took the SAT, mean ACT total score of those students who took the ACT, and percentage of students who are at or above criterion on the SAT or ACT of those students taking the SAT or ACT. Data from archival files from the Texas Education Agency's Academic Excellence Indicator System for each respective year of the eight-year longitudinal study was collected. Scheduling models (traditional, alternating block and accelerated block) were investigated. The sample was drawn from the student population of a large urban school district in north central Texas, a district serving approximately 77,000 students. The ...

The impact of computer assisted instruction on sensory cognitive factors in literacy learning.

The impact of computer assisted instruction on sensory cognitive factors in literacy learning.

Date: December 2003
Creator: Walton, Donna L.
Description: The purpose of this study was to examine the impact of computer assisted instruction on the development of literacy skills. The effect of instructional methodologies designed to stimulate sensory processing (auditory, visual, and somatic sensory) through information processing activities was analyzed. A software program was designed to present instruction to stimulate learning in one sensory modality, visual processing. Also, the effect of delivery mechanisms on the acquisition of literacy skills was investigated. Three treatment groups and a control group were established to analyze differences: cognitive processing methodologies presented via computer technology, conventional methodologies presented via computer technology, cognitive processing methodologies presented through traditional classroom tools, and a control group. A portable keyboard computer with word processing capabilities was selected to deliver technology-enhanced instruction. Results from this study suggest that activities designed to specifically promote processing in one sensory modality, do not promote acquisition of skills in other regions. There was no change in scores when visual methodologies were applied to auditory and somatic sensory cognitive processing goals. When spelling tests that utilized all sensory modalities were analyzed, visual processing instruction had no effect on achievement. This result was duplicated when tests requiring auditory processing skills were examined. However, when visual ...

A Study Of Correlations Between Learning Styles Of Students And Their Mathematics Scores On The Texas Assessment of Academic Skills Test

A Study Of Correlations Between Learning Styles Of Students And Their Mathematics Scores On The Texas Assessment of Academic Skills Test

Date: August 2001
Creator: Kopsovich, Rosalind D.
Description: The problem of this study was to determine whether learning styles of students affect their math achievement scores on the Texas Assessment of Academic Skills Test. The research questions addressed relevant to this study were: 1. Is there a positive correlation between students' learning styles and their achievement test scores in mathematics? 2. Is there a positive correlation between specific sub group's (as deemed by the state of Texas) and gender's learning styles and their achievement test scores in mathematics? The Pearson Product Moment Correlation coefficient and the Point-biserial correlation analysis was applied to the data collected from 500 fifth grade students attending a North Texas Intermediate school. The significance level was established at the .05 level. Part of the data was the student's responses to the Learning Style Inventory by Dunn, Dunn and Price. The findings established that the learning style preferences of all students in the area of persistence significantly impacted their math achievement scores. Gender and ethnicity were mitigating factors in the findings. These learning style preferences significantly impacted achievement in the following ways: * Caucasian students' preference of a high level of persistence in completing a difficult task. * Hispanic students' preference for a warm learning ...

Constructing transformative experiences through problem posing in a high school English research project.

Constructing transformative experiences through problem posing in a high school English research project.

Date: May 2009
Creator: Revelle, Carol L.
Description: 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.

The Relationship Among Effective School Correlates, School and District Practices, and Exemplary Student Performance in Texas

The Relationship Among Effective School Correlates, School and District Practices, and Exemplary Student Performance in Texas

Date: December 2007
Creator: Callender, Betty Darlene Miles
Description: The Texas Education Agency (TEA) annually rates campuses and districts on how well they meet standards of student performance. Since the high standard is so difficult for campuses and districts to reach, educators continually seek ways to improve student performance. The effective schools process is research-based and has stood the test of time. Descriptive statistics were used in this study to identify practices within the effective schools correlates that exemplary campuses implement. Campuses with long-term exemplary ratings were identified using the TEA data base. Campus site-based teams were surveyed using the More Effective Schools Staff Survey. Data was collected on elementary and secondary campuses with homogenous, diverse, economically advantaged, and economically disadvantaged student populations. District instructional leaders for those campuses completed a District Instructional Leader Survey to determine what practices districts implement to support their exemplary campuses. Findings from this quantitative study revealed what effective schools practices were highly evident on these exemplary campuses, regardless of diversity, economic status, district size, community type, property wealth, or location within the state. Findings also revealed that district leaders provide direction and support in the areas of (a) professional development; (b) beliefs, mission, and goals; (c) curriculum; (d) instruction; (e) assessment; and (f) ...

Texas Public School Principals' Application of Procedures in Identification and Prevention of Sexual Harassment

Texas Public School Principals' Application of Procedures in Identification and Prevention of Sexual Harassment

Access: Use of this item is restricted to the UNT Community.
Date: May 2002
Creator: Cramer, Conita K. Markel
Description: The procedural survey on sexual harassment procedures sent to 300 Texas principals had a response rate of 48.3 %. The mean score on the procedural survey for all 300 principals was 69.30 %. Eighteen research questions were addressed in detail in Chapter 4. Only five showed a significant correlation or effect size. Question 5 asked if there was a correlation between gender and the mean score of the survey instrument regarding sexual harassment procedures. The mean score of women was significantly higher than men. Question 6 asked if there was a correlation between the number of students in a school and the mean score of the survey instrument regarding sexual harassment procedures. This revealed that a significant correlation appeared between principals who worked at larger schools. Question 10 asked if there was a correlation between the location of the school, whether rural, urban, or metroplex and the mean score of the survey instrument. Principals of urban and metroplex schools scored significantly higher. Question 13 asked if there was a correlation between the hours of sexual harassment training attended in the last year and the mean score of the survey instrument regarding sexual harassment procedures. The results of this analysis revealed ...
