Detecting the presence of disease by unifying two methods of remote sensing.

Detecting the presence of disease by unifying two methods of remote sensing.

Date: May 2002
Creator: Reames, Steve
Description: There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to ...

Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction

Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: Bore, Julia Chelagat
Description: This study examined the effectiveness of employing videoconferencing and Web-based instruction in the preparation of special education personnel. Due to the acute shortage of special education personnel, it was anticipated that the use of videoconferencing and online instruction would provide a convenient way for students to attend class without having to travel to the actual location of the educational site. Further, it was believed that this initiative would result in higher student enrollment in special education teacher certification programs, consequently leading to an increase of personnel in the field. Moreover, the increase in personnel would enhance the ability of educational institutions to address the dismal academic, social, and behavioral outcomes of students with disabilities. Information for the study was collected from surveys that investigated how students perceived the use of videoconferencing and web-based instruction in the preparation of special education personnel. Ninety-four graduate students responded to the videoconferencing surveys while 88 responded to the Web-based instruction surveys. Six respondents were randomly selected to participate in face-to-face interviews designed to investigate the effectiveness of both approaches. Findings indicated that videoconferencing and Web-based instruction are convenient ways for students to attend class although videoconferencing sites may not be conveniently located to all ...

Date: May 2005
Creator: Pineau, Deborah M.
Description: The purpose of this study was to examine the usefulness of electronic-based questionnaires as a tool to gather data from field supervisors in the medical profession at various military bases. The study compared the response effects of an electronic evaluation questionnaire with the traditional method of paper-based questionnaires in gathering Level 3 data. The number of returns affects the amount of information available to the course personnel in creating a viable program that ensures the success of service members entering the occupational field and, ultimately, affecting the number of service members who remain beyond their first enlistment. The return rate and amount of missing data were tracked. Supervisors of graduates of a medical program who had observed service members for a minimum of 4-months were participants in the study. The z-test for comparing two proportions was used to determine significance of the study at the .05 level. Findings indicate that there was a significant difference in return rates and the amount of missing data when using the electronic format. Based on this study, the electronic-based questionnaire as a data-gathering tool provided a higher number of returns in a quicker time frame with fewer missing data in the technical training environment. ...

Effect of individualized curricular accommodations, incorporating student interest and the impact on the motivation and occurrence/ nonoccurrence of disruptive behavior displayed by students with emotional/behavioral disorders.

Effect of individualized curricular accommodations, incorporating student interest and the impact on the motivation and occurrence/ nonoccurrence of disruptive behavior displayed by students with emotional/behavioral disorders.

Date: December 2001
Creator: Teaff, Teresa L.
Description: As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for ...

The effect of professional development training for secondary mathematics teachers concerning nontraditional employment roles for females

The effect of professional development training for secondary mathematics teachers concerning nontraditional employment roles for females

Date: August 2002
Creator: Delp, Don J.
Description: This quasi-experimental study, utilizing quantitative and qualitative descriptive methods, examined the sex-egalitarian attitudes of secondary mathematics teachers from the Ft. Worth Independent School District. A video tape, Women in the Workplace, was used as a training intervention to test the effectiveness of professional development training in altering the mathematics teachers' sex-egalitarian attitudes towards female employment. Information on the video presented seven jobs that provide opportunities for female students in the science, engineering, and technology fields that are considered nontraditional jobs for females. Subjects completed 19 Employment Role domain questions on the King and King (1993) Sex-Role Egalitarianism Scale. A one-way ANOVA was applied to the data to test for a significant difference in the means of the control group, who did not see the video, and the experimental group that viewed the video. Findings concluded that there was no significant difference in the sex equalitarian mean scores of the control group and the experimental group. The research indicated that it takes an intensive and prolonged training period to produce a significant change in people's attitudes. This study supports the research on length of training needed to change sex egalitarian attitudes of classroom teachers. There were data collected on four demographic ...

The effect of psychological type, economic status, and minority

The effect of psychological type, economic status, and minority

Date: May 2001
Creator: Kays, Brenda S.
Description: The purpose of this study was to determine if psychological type, economic status, and minority classification had an effect on the pass/fail rates of vocational nursing students. The rationale for conducting this study was based on the need for the institution to maintain program viability and successfully retain students. The personality types of vocational nursing students were measured using the Myers-Briggs Type Indicator. Measures of economic status and minority classification were obtained through subject self-report. Students enrolled in a vocational nursing program at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was a statistically significant relationship between the pass/fail rates of thinkers versus feelers in the vocational nursing classroom. Findings did not indicate a statistically significant relationship between the pass/fail rates of extraverts versus introverts; sensers versus intuitives; or judgers versus perceivers in the vocational nursing classroom. Findings also suggested that there were no significant relationships between the pass/fail rates of individuals with poverty versus non-poverty economic statuses, nor between individuals with minority versus non-minority classifications. Based on this study, vocational nursing students psychologically typed as thinkers, may have lower passing rates in ...

The effects of a career education program on the career choices of fifth-grade students.

The effects of a career education program on the career choices of fifth-grade students.

Date: December 2005
Creator: Barton-Cox, Florence Faye
Description: The career development of students, demonstrated by students' career interest, is important for a more effective career education program. This study focused on the career choices of fifth grade students through the use of a career interest inventory before and after the use of a career education program. The design was experimental, and the purpose was to determine if there were differences in the career interest of fifth grade students who participated in a career education program compared with the career interest of fifth grade students who did not participate in a career education program. The COPS-PIC Picture Inventory of Careers (COPS-PIC) was used as a pretest and posttest for fifth grade students to determine baseline career interests. The COPS-PIC career inventory results were incorporated into the career education program and served as a career planning guide for incorporating students' input into career choices and exploration of those choices for a better understanding of the process of finding out who they want to be and what type of careers exists. The experimental group was provided instruction and career exploration opportunities for 4 weeks. The control group was not provided career education instruction and career exploration opportunities. This study suggests that ...

Effects of a simulation game on trainees' knowledge and attitudes about age-related changes in learning and work behaviors of older workers

Effects of a simulation game on trainees' knowledge and attitudes about age-related changes in learning and work behaviors of older workers

Date: May 2000
Creator: Dunn, Suzanne
Description: This investigation was conducted in response to the need for effective diversity awareness programs to help employers create intergenerational-friendly work environments. An experimental pre- and post-test control group randomized block design was employed to answer two research questions about the effects of a simulation game on knowledge and attitudes about age-related changes in learning and work behaviors of older workers. Participants were assessed immediately prior to and following the treatment, followed by a third assessment 60 days later. Necessary measures were taken to control for threats to the study's internal validity. An applicant pool comprised of human resource management and development practitioners and senior undergraduate students enrolled in human resource management courses yielded a sample of 65 participants. Chapter one introduces the study. Chapter two provides a review and summary of relevant literature on ageism in the workplace, training older workers, and simulation games. Chapter three describes the procedures and methods used to answer the research questions. Chapter four presents the results of all analytic procedures related to the investigation. Chapter five provides the conclusions and recommendations based on the findings of this investigation. In this investigation, the treatment group did not score significantly higher on their knowledge of age-related ...

The effects of ARCS-based confidence strategies on learner confidence and performance in distance education.

The effects of ARCS-based confidence strategies on learner confidence and performance in distance education.

Date: May 2006
Creator: Huett, Jason Bond
Description: The purpose of this research was to manipulate the component of confidence found in Keller's ARCS model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas university using SAM 2003 software delivery. This study also tested whether the aforementioned confidence tactics had any unintentional effect on the remaining attention, relevance, and satisfaction subscales of the ARCS model as well as on learners' overall motivation for the class and the instructional materials. This study was conducted over a 5.5-week period with an initial sample of 81 total students. Two quantitative surveys were used to measure confidence and motivation: (a) the Course Interest Survey (CIS), and (b) the Instructional Materials Motivation Survey (IMMS). The results indicated that the treatment group showed statistically greater gains than the control group in terms of learner confidence on the CIS but not the IMMS. In terms of performance, the treatment group outperformed the control group on all of the individual posttest measures and on the overall aggregate mean performance score. The results showed no statistically significant difference on the attention subsection of the ARCS model. However, statistically significant differences were noted for the relevance and satisfaction subscales of ...

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 ...
