CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

Date: December 2002
Creator: Swartz Horn, Rebecca
Description: The problem with which this study is concerned is articulating all possible CT3 and KR21 reliability measures for every case of a 5x5 binary matrix (32,996,500 possible matrices). The study has three purposes. The first purpose is to calculate CT3 for every matrix and compare the results to the proposed optimum range of .3 to .5. The second purpose is to compare the results from the calculation of KR21 and CT3 reliability measures. The third purpose is to calculate CT3 and KR21 on every strand of a class test whose item set has been reduced using the difficulty strata identified by Order Analysis. The study was conducted by writing a computer program to articulate all possible 5 x 5 matrices. The program also calculated CT3 and KR21 reliability measures for each matrix. The nonparametric technique of Order Analysis was applied to two sections of test items to stratify the items into difficulty levels. The difficulty levels were used to reduce the item set from 22 to 9 items. All possible strands or chains of these items were identified so that both reliability measures (CT3 and KR21) could be calculated. One major finding of this study indicates that .3 to .5 ...

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Diagnosing Learner Deficiencies in Algorithmic Reasoning

Date: May 1995
Creator: Hubbard, George U.
Description: It is hypothesized that useful diagnostic information can reside in the wrong answers of multiple-choice tests, and that properly designed distractors can yield indications of misinformation and missing information in algorithmic reasoning on the part of the test taker. In addition to summarizing the literature regarding diagnostic research as opposed to scoring research, this study proposes a methodology for analyzing test results and compares the findings with those from the research of Birenbaum and Tatsuoka and others. The proposed method identifies the conditions of misinformation and missing information, and it contains a statistical compensation for careless errors. Strengths and weaknesses of the method are explored, and suggestions for further research are offered.

Discovering a descriptive taxonomy of attributes of exemplary school library Websites

Discovering a descriptive taxonomy of attributes of exemplary school library Websites

Date: August 2007
Creator: Valenza, Joyce Kasman
Description: This descriptive study examines effective online school library practice. A Delphi panel selected a sample of 10 exemplary sites and helped to create two research tools--taxonomies designed to analyze the features and characteristics of school library Websites. Using the expert-identified sites as a sample, a content analysis was conducted to systematically identify site features and characteristics. Anne Clyde's longitudinal content analysis of school library Websites was used as a baseline to examine trends in practice; in addition, the national guidelines document, Information Power: Building Partnerships for Learning, was examined to explore ways in which the traditional mission and roles of school library programs are currently translated online. Results indicated great variation in depth and coverage even among Websites considered exemplary. Sites in the sample are growing more interactive and student-centered, using blogs as supplemental communication strategies. Nevertheless, even these exemplary sites were slow to adopt the advances in technology to meet the learning needs and interests of young adult users. Ideally the study's findings will contribute to understanding of state-of-the-art and will serve to identify trends, as well as serving as a guide to practitioners in planning, developing, and maintaining school library Websites.

An E-government Readiness Model

An E-government Readiness Model

Date: December 2001
Creator: Liu, Shin-Ping
Description: The purpose of this study is to develop an e-government readiness model and to test this model. Consistent with this model several instruments, IS assessment (ISA), IT governance (ITG), and Organization-IS alignment (IS-ALIGN) are examined for their ability to measure the readiness of one organization for e-government and to test the instruments fit in the proposed e-government model. The ISA instrument used is the result of adapting and combining the IS-SERVQUAL instrument proposed by Van Dyke, Kappelman, and Pybutok (1997), and the IS-SUCCESS instrument developed by Kappelman and Chong (2001) for the City of Denton (COD) project at UNT. The IS Success Model was first proposed by DeLone and McLean (1992), but they did not validate this model. The ITG instrument was based on the goals of the COD project for IT governance and was developed by Sanchez and Kappelman (2001) from UNT. The ISALIGN instrument was also developed by Sanchez and Kappelman (2001) for the COD project. It is an instrument based on the Malcolm Baldrige National Quality Award (MBNQA) that measures how effectively a government organization utilizes IT to support its various objectives. The EGOV instrument was adapted from the study of the Action-Audience Model developed by Koh ...

The effect of information literacy instruction on library anxiety among international students.

The effect of information literacy instruction on library anxiety among international students.

Access: Use of this item is restricted to the UNT Community.
Date: May 2004
Creator: Battle, Joel C.
Description: This study explored what effect information literacy instruction (ILI) may have on both a generalized anxiety state and library anxiety specifically. The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college students and is characterized by feelings of negative emotions including, ruminations, tension, fear and mental disorganization (Jiao & Onwuegbuzie, 1999a). This often occurs when a student contemplates conducting research in a library and is due to any number of perceived inabilities about using the library. In order for students to become successful in their information seeking behavior this anxiety needs to be reduced. The study used two groups of international students enrolled in the English for Speakers of other Languages (ESOL) program taking credit courses. Each student completed Bostick's Library Anxiety Scale (LAS) and Spielberger's State-Trait Anxiety Inventory (STAI) to assess anxiety level before and after treatment. Subjects were given a research assignment that required them to use library resources. Treatment: Group 1 (experimental group) attended several library instruction classes (the instruction used Kuhltau's information search ...

The effect of personality type on the use of relevance criteria for purposes of selecting information sources.

The effect of personality type on the use of relevance criteria for purposes of selecting information sources.

Date: December 2002
Creator: Sims, Dale B.
Description: Even though information scientists generally recognize that relevance judgments are multidimensional and dynamic, there is still discussion and debate regarding the degree to which certain internal (cognition, personality) and external (situation, social relationships) factors affect the use of criteria in reaching those judgments. Much of the debate centers on the relationship of those factors to the criteria and reliable methods for measuring those relationships. This study researched the use of relevance criteria to select an information source by undergraduate students whose task it is to create a course schedule for a semester. During registration periods, when creating their semester schedules, students filled out a two-part questionnaire. After completion of the questionnaire the students completed a Myers-Briggs Type Indicator instrument in order to determine their personality type. Data was analyzed using one-way ANOVAS and Chi-Square. A positive correlation exists between personality type as expressed by the MBTI and the information source selected as most important by the subject. A correlation also exists between personality type and relevance criteria use. The correlation is stronger for some criteria than for others. Therefore, one can expect personality type to have an effect on the use of relevance criteria while selecting information sources.

The effectiveness of using LEGO Mindstorms robotics activities to influence self-regulated learning in a university introductory computer programming course.

The effectiveness of using LEGO Mindstorms robotics activities to influence self-regulated learning in a university introductory computer programming course.

Date: May 2008
Creator: McWhorter, William Isaac
Description: The research described in this dissertation examines the possible link between self-regulated learning and LEGO Mindstorms robotics activities in teaching concepts in an introductory university computer programming course. The areas of student motivation, learning strategies, and mastery of course objectives are investigated. In all three cases analysis failed to reveal any statistically significant differences between the traditional control group and the experimental LEGO Mindstorms group as measured by the Motivated Strategies for Learning Questionnaire and course exams. Possible reasons for the lack of positive results include technical problems and limitations of the LEGO Mindstorms systems, limited number and availability of robots outside of class, limited amount of time during the semester for the robotics activities, and a possible difference in effectiveness based on gender. Responses to student follow-up questions, however, suggest that at least some of the students really enjoyed the LEGO activities. As with any teaching tool or activity, there are numerous ways in which LEGO Mindstorms can be incorporated into learning. This study explores whether or not LEGO Mindstorms are an effective tool for teaching introductory computer programming at the university level and how these systems can best be utilized.

The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology

The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology

Access: Use of this item is restricted to the UNT Community.
Date: May 1999
Creator: Bell, Thomas
Description: The objectives of this study were (1) to identify and describe task-based documentation; (2) to identify and describe any purported changes in users attitudes when IT migration was preceded by task-based documentation; (3) to suggest implications of task-based documentation on users attitude toward IT acceptance. Questionnaires were given to 150 university students. Of these, all 150 students participated in this study. The study determined the following: (1) if favorable pre-implementation attitudes toward a new e-mail system increase, as a result of training, if users expect it to be easy to learn and use; (2) if user acceptance of an e-mail program increase as expected perceived usefulness increase as delineated by task-based documentation; (3) if task-based documentation is more effective than standard help menus while learning a new application program; and (4) if training that requires active student participation increase the acceptance of a new e-mail system. The following conclusions were reached: (1) Positive pre-implementation attitudes toward a new e-mail system are not affected by training even if the users expect it to be easy to learn and use. (2) User acceptance of an e-mail program does not increase as perceived usefulness increase when aided by task-based documentation. (3) Task-based documentation ...

An Empirical Investigation of Critical Factors that Influence Data Warehouse Implementation Success in Higher Educational Institutions

An Empirical Investigation of Critical Factors that Influence Data Warehouse Implementation Success in Higher Educational Institutions

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Mukherjee, Debasish
Description: Data warehousing (DW) in the last decade has become the technology of choice for building data management infrastructures to provide organizations the decision-making capabilities needed to effectively carry out its activities. Despite its phenomenal growth and importance to organizations the rate of DW implementation success has been less than stellar. Many DW implementation projects fail due to technical or organizational reasons. There has been limited research on organizational factors and their role in DW implementations. It is important to understand the role and impact of both technical but organizational factors in DW implementations and their relative importance to implementation performance. A research model was developed to test the significance of technical and organizational factors in the three phases of implementation with DW implementation performance. The independent variables were technical (data, technology, and expertise) and organizational (management, goals, users, organization). The dependent variable was performance (content, accuracy, format, ease of use, and timeliness). The data collection method was a Web based survey of DW implementers and DW users sampled (26) from a population of 108 identified DW implementations. Regression was used as the multivariate statistical technique to analyze the data. The results show that organization factors are significantly related to performance. ...
