Diagnosing Learner Deficiencies in Algorithmic Reasoning

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 Bire… more

Increasing Telecommunications Channel Capacity: Impacts on Firm Profitability

Description: In calling for the deployment of high-capacity telecommunications infrastructures, the Clinton Administration is relying on market forces to drive demand toward self-sustaining development. There is little doubt that many firms will embrace the new telecommunications services for a variety of reasons including market differentiation, vertical market integration, and other organization-specific factors. However, there is little evidence at the firm level that adopting the use of increased-capaci… more

Korean Studies in North America 1977-1996: A Bibliometric Study

Description: This research is a descriptive bibliometric study of the literature of the field of Korean studies. Its goal is to quantitatively describe the literature and serve as a model for such research in other area studies fields. This study analyzed 193 source articles and 7,166 citations in the articles in four representative Korean and Asian studies journals published in North America from 1977 to 1996. The journals included in this study were Korean Studies (KS), the Journal of Korean Studies (JKS)… more

Information Seeking in a Virtual Learning Environment

Description: Duplicating a time series study done by Kuhlthau and associates in 1989, this study examines the applicability of the Information Search Process (ISP) Model in the context of a virtual learning environment. This study confirms that students given an information seeking task in a virtual learning environment do exhibit the stages indicated by the ISP Model. The six-phase ISP Model is shown to be valid for describing the different stages of cognitive, affective, and physical tasks individuals pr… more

A Personal Documenation System for Scholars: A Tool for Thinking

Description: This exploratory research focused on a problem stated years ago by Vannevar Bush: "The problem is how creative men think, and what can be done to help them think." The study explored the scholarly work process and the use of computer tools to augment thinking. Based on a review of several related literatures, a framework of 7 major categories and 28 subcategories of scholarly thinking was proposed. The literature was used to predict problems scholars have in organizing their information, potent… more

A Theory for the Measurement of Internet Information Retrieval

Description: The purpose of this study was to develop and evaluate a measurement model for Internet information retrieval strategy performance evaluation whose theoretical basis is a modification of the classical measurement model embodied in the Cranfield studies and their progeny. Though not the first, the Cranfield studies were the most influential of the early evaluation experiments. The general problem with this model was and continues to be the subjectivity of the concept of relevance. In cyberspace, … more

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

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 att… more

An Analysis of the Ability of an Instrument to Measure Quality of Library Service and Library Success

Description: This study consisted of an examination of how service quality should be measured within libraries and how library service quality relates to library success. A modified version of the SERVQUAL instrument was evaluated to determine how effectively it measures library service quality. Instruments designed to measure information center success and information system success were evaluated to determine how effectively they measure library success and how they relate to SERVQUAL. A model of library … more

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

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 … more

Shifts of Focus Among Dimensions of User Information Problems as Represented During Interactive Information Retrieval

Description: The goal of this study is to increase understanding of information problems as they are revealed in interactions among users and search intermediaries during information retrieval. Specifically, this study seeks to investigate: (a) how interaction between users and search intermediaries reveals aspects of user information problems; (b) to explore the concept of representation with respect to information problems in interactive information retrieval; and (c) how user and search intermediaries fo… more

Factors Influencing How Students Value Asynchronous Web Based Courses

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 uncover… more
