The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance

The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance

Date: December 2006
Creator: Menking, Ricky Arnold
Description: Database modeling is a complex conceptual topic often taught through the use of project-based teams. One of the problems with the use of project-based teams in university courses is the determination of whether this is the most effective use of instructor and student time involvement and effort level. Therefore, this study investigated the impact of providing team dynamics training prior to the commencement of short-duration project-based team conceptual data modeling projects on individual data modeling task performance (DMTP) outcomes and team cohesiveness. The literature review encompassed conceptual data design modeling, the use of a project-based team approach, team dynamics and cohesion, self-efficacy, gender, and diversity. The research population consisted of 75 university students at a North American University (Canadian) pursuing a business program requiring an information systems course in which database design components are taught. Analysis of the collected data revealed that there was a statistically significant inverse relationship found between the provision of team dynamics training and individual DMTP. However, no statistically significant relationship was found between team dynamics training and team cohesion. Therefore, this study calls into question the value of team dynamics training on learning outcomes in the case of very short duration project-based teams involved in ...

Description: 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 ...

Emotional/behavioral disturbance and speech/language disorders: Prevalence of the dual diagnoses in a school-age population

Emotional/behavioral disturbance and speech/language disorders: Prevalence of the dual diagnoses in a school-age population

Date: May 2000
Creator: Silver, Kathi Olinsky
Description: The purpose of this study was to examine the prevalence of the comorbidity of emotional/behavioral disorders (EBD) and speech/language disorders among those students identified as under The Individuals With Disabilities Education Act criteria as emotionally disturbed and speech impaired. The literature reviewed included clinical and school settings that examined a cooccurrence of language disorders in the EBD population. Other research reported a lack of routine involvement of speech/language therapists in the assessment of the EBD population. Implications from clinical studies suggested a need for greater attention to language disorders in a multi- and interdisciplinary assessment. This study investigated the prevalence of the dual occurrence of EBD and speech/language disorders in Grades 2 through 6 in Texas schools in light of the known research. Relationships in ethnicity and socioeconomic status were examined using chi-square test of independence. Aggregate data were obtained from the database of the Texas Pupil Information Management System and from survey questionnaire responses provided by speech therapists in selected districts. The literature review focused on the impact of language in the development of appropriate personal interactions and communication skills, especially those relevant to pragmatic language factors and the implications of language competency in successful personal living and career ...

Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains

Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains

Date: December 1998
Creator: McCrary, Donna E. (Donna Evelyn)
Description: The Ecologically-Based Activity Plan (EBAP) is proposed as a method to create a transition between special education and general education. It serves as a tool to help classroom teachers assess the environment of the class and as a method for embedding instruction within the naturally occurring context of the endogenous constructivist classroom. In this study the EBAP was used to reduce aggressive behavior and increase prosocial behavior among five children who displayed developmental delays in the social and emotional domains.

Enhanced learning performance in the middle school classroom through increased student motivation, by the use of educational software and question-based gaming technology.

Enhanced learning performance in the middle school classroom through increased student motivation, by the use of educational software and question-based gaming technology.

Date: December 2006
Creator: Dorr, David L.
Description: The purpose of this research was to determine if the introduction of a competitive and collaborative computer-based gaming software system into middle school classrooms would result in improved attendance and grades, and motivate students to have a greater interest in their studies. This study was conducted over a 6 week period, with attendance and performance data being collected from 284 students. Two quantitative surveys were used to measure course interest and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). Participation in these surveys consisted of 84 students taking the CIS and 40 students taking the IMMS. The results indicated that the experimental group showed statistically better scores than the comparison group in attendance and performance. Students participating in the experimental group had significantly lower mean ranks of absenteeism compared to students in the comparison group. Results also revealed significant differences on grades. Students that were in the experimental group had significantly higher grades compared to students that were in the comparison group. Results of the CIS suggest that a statistically significant difference does not exist on Attention, Relevance, Confidence, and Satisfaction between the experimental and comparison groups. Results of the means and standard ...

Enhancing skill maintenance through relapse prevention strategies: a comparison of two models.

Enhancing skill maintenance through relapse prevention strategies: a comparison of two models.

Date: May 2004
Creator: Hutchins, Holly M.
Description: In a quasi-experimental field study, two posttraining interventions composed of relapse prevention (RP) strategies were compared and tested for the effects on participant transfer outcomes. Participant retention of training content, skill maintenance, use of relapse prevention strategies, and self-efficacy served as the dependent variables. Self-efficacy was also tested as a mediator between the experimental treatment levels and both participant skill maintenance and participant use of RP strategies. Participants (n = 39) included managers, directors, and supervisors from various departments within a multi-national telecommunications organization located in a large southern city. After participating in a four-hour leadership development training, two of the three groups participated in a 30-40 minute training where they received one of two RP interventions. One intervention included the steps of (1) identifying potential obstacles to positive training transfer, (2) predicting the first lapse to pretraining behavior, and (3) applying relevant coping strategies to thwart a lapse. The alternative RP intervention included the same steps in addition to a goal setting step. Descriminant descriptive analysis was used to test for group differences across the response variables and to identify on which variables the groups differed. Three separate regression equations were used to test for the mediating relationship of ...

Equivalency of paper-pencil tests and computer-administered tests.

Equivalency of paper-pencil tests and computer-administered tests.

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Whitworth, Clifford K.
Description: Are computer-administered versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that have caused differences when not controlled. To prove equivalency between test modes, scores have to have similar means, dispersions, and shapes; the ranked-order of the scores must also be similar. Four tests were given over the course of a 16-week semester. The sample was divided, half taking paper-pencil tests and half taking the same test administered by a computer. The mode of administration was switched with each test administration. The analysis showed that, when the intervening variables were controlled, the two modes of administration were equivalent. The analysis used a 2x4 ANOVA, which showed no difference between test modes, but showed that each test administration was significantly different. The Levene statistic was used to test whether dispersions were equivalent and confidence intervals were established to test the kurtosis and skewness statistics. Finally, each of the test scores were transformed into their Normal Curve Equivalents so that Pearson's coefficient could be used to determine the equivalency of the ...

Establishing the utility of a classroom effectiveness index as a teacher accountability system.

Establishing the utility of a classroom effectiveness index as a teacher accountability system.

Date: May 2002
Creator: Bembry, Karen L.
Description: How to identify effective teachers who improve student achievement despite diverse student populations and school contexts is an ongoing discussion in public education. The need to show communities and parents how well teachers and schools improve student learning has led districts and states to seek a fair, equitable and valid measure of student growth using student achievement. This study investigated a two stage hierarchical model for estimating teacher effect on student achievement. This measure was entitled a Classroom Effectiveness Index (CEI). Consistency of this model over time, outlier influences in individual CEIs, variance among CEIs across four years, and correlations of second stage student residuals with first stage student residuals were analyzed. The statistical analysis used four years of student residual data from a state-mandated mathematics assessment (n=7086) and a state-mandated reading assessment (n=7572) aggregated by teacher. The study identified the following results. Four years of district grand slopes and grand intercepts were analyzed to show consistent results over time. Repeated measures analyses of grand slopes and intercepts in mathematics were statistically significant at the .01 level. Repeated measures analyses of grand slopes and intercepts in reading were not statistically significant. The analyses indicated consistent results over time for reading ...

An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.

An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.

Date: May 2002
Creator: Webb, Ruth Sherrill
Description: The purpose of this study was to examine the potential of three independent psychological scales (Rotter's Locus of Control, Karasek's Job Content Questionnaire [non-injury job stress], and Rosenberg's Self-Esteem Scale) to predict job satisfaction, as measured by Brayfield and Rothe's Index of Job Satisfaction, among salespersons in a small independent department store in Wichita Falls, Texas. An 82-item survey which examined the dynamics of a salesperson's work life was administered to 20 individuals who were full-time employees of the department store. Demographic data were also gathered although these factors were not entered into the regression analysis. A multiple regression procedure examined the responses of the 20 employees who participated in the study. The R-squared coefficient indicates that 41 percent of the variance in Job Satisfaction was explained by the three predictor measures. A major proportion of this unexplained variance may be in variables outside the scope of this study, e.g., salaries, vacation time, benefits, bonuses, or commissions. Results suggest that the independent variables measured by the Locus of Control Scale and the Job Content Questionnaire in combination were the best predictors of job satisfaction with a significance level of .01. The single best predictor was the Job Content Questionnaire, significant ...

Creator: McVay, Richard B.
Description: The purpose of this study was to determine whether varying levels of computer anxiety have an effect on computer-based testing of United States Air Force technical training students. The first chapter presents an overview of computer-based testing, defines key terms, and identifies questions addressed in the research. The rationale for conducting this study was that little research had been done in this area. The second chapter contains a review of the pertinent literature related to computer-based testing, computer anxiety, test reliability, validity, and gender differences in computer use. Due to the lack understanding concerning any effects of computer anxiety on computer-based testing, this has been a worthwhile topic to explore, and it makes a significant contribution to the training field. The third chapter describes the qualitative research methodology used to conduct the study. The primary methodology was an analysis of variance comparison for groups of individuals who displayed high or low computer anxiety to their respective mean computer-based or paper-based aircraft maintenance knowledge testing scores. The research population consisted of United States Air Force aircraft maintenance craftsmen students attending training at Sheppard Air Force Base, Texas. The fourth chapter details the findings of the study. The findings indicate that there ...
