Empowering agent for Oklahoma school learning  Communities:  an examination of the Oklahoma Library Improvement Program

Empowering agent for Oklahoma school learning Communities: an examination of the Oklahoma Library Improvement Program

Date: August 2000
Creator: Jenkins, Carolyn Sue Ottinger
Description: The purposes of this study were to determine the initial impact of the Oklahoma Library Media Improvement Grants on Oklahoma school library media programs; assess whether the Oklahoma Library Media Improvement Grants continue to contribute to Oklahoma school learning communities; and examine possible relationships between school library media programs and student academic success. It also seeks to document the history of the Oklahoma Library Media Improvement Program 1978 - 1994 and increase awareness of its influence upon the Oklahoma school library media programs. Methods of data collection included: examining Oklahoma Library Media Improvement Program archival materials; sending a survey to 1703 school principals in Oklahoma; and interviewing Oklahoma Library Media Improvement Program participants. Data collection took place over a one year period. Data analyses were conducted in three primary phases: descriptive statistics and frequencies were disaggregated to examine mean scores as they related to money spent on school library media programs; opinions of school library media programs; and possible relationships between school library media programs and student academic achievement. Analysis of variance was used in the second phase of data analysis to determine if any variation between means was significant as related to Oklahoma Library Improvement Grants, time spent in ...

Evaluation of Text-Based and Image-Based Representations for Moving Image Documents

Evaluation of Text-Based and Image-Based Representations for Moving Image Documents

Date: August 1997
Creator: Goodrum, Abby A. (Abby Ann)
Description: Document representation is a fundamental concept in information retrieval (IR), and has been relied upon in textual IR systems since the advent of library catalogs. The reliance upon text-based representations of stored information has been perpetuated in conventional systems for the retrieval of moving images as well. Although newer systems have added image-based representations of moving image documents as aids to retrieval, there has been little research examining how humans interpret these different types of representations. Such basic research has the potential to inform IR system designers about how best to aid users of their systems in retrieving moving images. One key requirement for the effective use of document representations in either textual or image form is thedegree to which these representations are congruent with the original documents. A measure of congruence is the degree to which human responses to representations are similar to responses produced by the document being represented. The aim of this study was to develop a model for the representation of moving images based upon human judgements of representativeness. The study measured the degree of congruence between moving image documents and their representations, both text and image based, in a non-retrieval environment with and without task ...

An Evaluation of the Effect of Learning Styles and Computer Competency on Students' Satisfaction on Web-Based Distance Learning Environments

An Evaluation of the Effect of Learning Styles and Computer Competency on Students' Satisfaction on Web-Based Distance Learning Environments

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Du, Yunfei
Description: This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

An Examination Of The Variation In Information Systems Project Cost Estimates: The Case Of Year 2000 Compliance Projects

An Examination Of The Variation In Information Systems Project Cost Estimates: The Case Of Year 2000 Compliance Projects

Date: May 2000
Creator: Fent, Darla
Description: The year 2000 (Y2K) problem presented a fortuitous opportunity to explore the relationship between estimated costs of software projects and five cost influence dimensions described by the Year 2000 Enterprise Cost Model (Kappelman, et al., 1998) -- organization, problem, solution, resources, and stage of completion. This research was a field study survey of (Y2K) project managers in industry, government, and education and part of a joint project that began in 1996 between the University of North Texas and the Y2K Working Group of the Society for Information Management (SIM). Evidence was found to support relationships between estimated costs and organization, problem, resources, and project stage but not for the solution dimension. Project stage appears to moderate the relationships for organization, particularly IS practices, and resources. A history of superior IS practices appears to mean lower estimated costs, especially for projects in larger IS organizations. Acquiring resources, especially external skills, appears to increase costs. Moreover, projects apparently have many individual differences, many related to size and to project stage, and their influences on costs appear to be at the sub-dimension or even the individual variable level. A Revised Year 2000 Enterprise Model is presented incorporating this granularity. Two primary conclusions can ...

An experimental study of teachers' verbal and nonverbal immediacy, student motivation, and cognitive learning in video instruction

An experimental study of teachers' verbal and nonverbal immediacy, student motivation, and cognitive learning in video instruction

Date: May 2000
Creator: Witt, Paul L.
Description: This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to enhance learning; and second, how immediacy affects cognitive learning in relation to student motivation. These questions were examined in the context of video instruction to provide insight into distance learning processes and to ensure maximum control over experimental manipulations. Participants (N = 347) were drawn from university students in an undergraduate communication course. Students were randomly assigned to groups, completed a measure of state motivation, and viewed a 15-minute video lecture containing part of the usual course content delivered by a guest instructor. Participants were unaware that the video instructor was actually performing one of four scripted manipulations reflecting higher and lower combinations of specific verbal and nonverbal cues, representing the four cells of the 2x2 research design. Immediately after the lecture, students completed a recall measure, consisting of portions of the video text with blanks in the place of key words. Participants were to fill in the blanks with exact words they recalled from the videotape. ...

An exploration of the diffusion of a new technology from communities of practice perspective: Web services technologies in digital libraries.

An exploration of the diffusion of a new technology from communities of practice perspective: Web services technologies in digital libraries.

Date: August 2007
Creator: Oguz, Fatih
Description: This study explored and described decision factors related to technology adoption. The research used diffusion of innovations and communities of practice (CoP) theoretical frameworks and a case study of Web services technology in the digital library (DL) environment to develop an understanding of the decision-making process. A qualitative case study approach was used to investigate the research problems and data were collected through semi-structured interviews, documentary evidence (e.g., meeting minutes), and a comprehensive member check. The research conducted face-to-face and phone interviews with seven respondents with different job titles (administraive vs. technical) from five different DL programs selected based on distinctive characteristics such as size of the DL program. Findings of the research suggested that the decision-making process is a complex process in which a number of factors are considered when making technology adoption decisions. These factors are categorized as organizational, individual, and technology specific factors. Further, data showed that DL CoPs played an important role in enabling staff members of a DL program to access up-to-date and experienced-based knowledge, provided a distributed problem solving and learning environment, facilitating informal communication and collaborative activities, and informing the decision-making process.

An exploratory study of factors that influence student user success in an academic digital library.

An exploratory study of factors that influence student user success in an academic digital library.

Date: December 2007
Creator: Rahman, Faizur
Description: The complex nature of digital libraries calls for appropriate models to study user success. Calls have been made to incorporate into these models factors that capture the interplay between people, organizations, and technology. In order to address this, two research questions were formulated: (1) To what extent does the comprehensive digital library user success model (DLUS), based on a combination of the EUCS and flow models, describe overall user success in a prototype digital library environment; and (2) To what extent does a combined model of DeLone & McLean's reformulated information system success model and comprehensive digital library user success model (DLUS) explain digital library user success in a prototype digital library environment? Participants were asked to complete an online survey questionnaire. A total of 160 completed and useable questionnaires were obtained. Data analyses through exploratory and confirmatory factor analyses and structural equation modeling produced results that support the two models. However, some relationships between latent variables hypothesized in the model were not confirmed. A modified version of the proposed comprehensive plus user success model in a digital library environment was tested and supported through model fit statistics. This model was recommended as a possible alternative model of user success. ...

Factors Influencing How Students Value Asynchronous Web Based Courses

Factors Influencing How Students Value Asynchronous Web Based Courses

Date: December 1999
Creator: PĂ©rez Cereijo, Maria Victoria
Description: This dissertation discovered the factors influencing how students value asynchronous Web-based courses through the use of qualitative methods. Data was collected through surveys, observations, interviews, email correspondence, chat room and bulletin board transcripts. Instruments were tested in pilot studies of previous semesters. Factors were identified for two class formats. The asynchronous CD/Internet class format and the synchronous online Web based class format. Also, factors were uncovered for two of the instructional tools used in the course: the WebCT forum and WebCT testing. Factors were grouped accordingly as advantages or disadvantages under major categories. For the asynchronous CD/Internet class format the advantages were Convenience, Flexibility, Learning Enhancement, and Psychology. The disadvantages included Isolation, Learning Environment, and Technology. For the synchronous online Web based class format the advantages were Convenience, Flexibility, Human Interaction, Learning Enhancement and Psychology, whereas the disadvantages included Isolation, Learning Environment and Technology. Concurrently, the study revealed the following factors as advantages of the WebCT Forum: Help Each Other, Interaction, Socialization, Classroom News, and Time Independent. The disadvantages uncovered were Complaints, Technical Problems and Isolation. Finally, advantages specified for the WebCT testing tool were Convenience, Flexibility and Innovations, and its disadvantages were Surroundings Not Conducive to Learning, and Technical ...

Factors Influencing Older Adults' Patterns of Information Acquisition

Factors Influencing Older Adults' Patterns of Information Acquisition

Date: May 1989
Creator: Barnett, Mary Jane, 1952-
Description: A group of 101 older adults (sixty-five years of age and over) who lived independently in three retirement apartment residences in Denton, Texas, were asked about their patterns of reading, television viewing, and radio listening habits for two periods in their lives: (1) at age forty to fifty-five and (2) at the present. Respondents were asked about their use of external information sources (public library, grocery store, newsstand, etc.) and their use of proximate information sources (radio, friends/relatives, television, etc.) They were also asked about access to transportation, income satisfaction, status of general health, vision, hearing, physical mobility and reasons for utilizing various information sources. Four hypotheses relating changes in health, environment, economic status, and education to reasons for reading and use of information sources were tested through the use of t-tests, regression analysis and analysis of variance. Within this group of older adults, use of external information sources decreased from the past to the present. There was, however, no change in the use of information sources located in or near the residence as difficulties in these areas increased. A relationship was found between educational level and reading for pleasure earlier in life. Also, those with higher educational levels reported ...

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

Factors Related to Mississippi School Library Media Centers in Multitype Cooperation

Date: May 1988
Creator: Partridge, Margaret
Description: The main purpose of this study was to identify the major obstacles to cooperation as perceived by school library media specialists in the state of Mississippi and to determine if members of the Coastal Mississippi Library Cooperative (CMLC) believe that there are fewer obstacles to cooperation than do non-members. The secondary purpose was to evaluate the CMLC to some extent to determine if success was achieved through organization when defined by the variables, planning, governance, funding, communication, administration, and evaluation. The population of the study was all of the librarians (academic, public, school, and special) in the six-county area which comprises the CMLC, and a random sample of public school librarians throughout the remainder of the state. All of the school librarians were sent a questionnaire that requested their responses to statements of barriers to cooperation. All of the librarians in the CMLC region were sent a questionnaire to obtain their perceptions of participation in the CMLC. Pour librarians, members of the CMLC, were Interviewed to obtain information on the organizational factors of the CMLC. Data received from school library media specialists were submitted to various statistical tests. The Chi-Square statistic was used on the demographic portion of the questionnaire, ...
