Smoothing the information seeking path: Removing representational obstacles in the middle-school digital library.

Date: May 2002
Creator: Abbas, June M.
Description: Middle school student's interaction within a digital library is explored. Issues of interface features used, obstacles encountered, search strategies and search techniques used, and representation obstacles are examined. A mechanism for evaluating user's descriptors is tested and effects of augmenting the system's resource descriptions with these descriptors on retrieval is explored. Transaction log data analysis (TLA) was used, with external corroborating achievement data provided by teachers. Analysis was conducted using quantitative and qualitative methods. Coding schemes for the failure analysis, search strategies and techniques analysis, as well as extent of match analysis between terms in student's questions and their search terms, and extent of match analysis between search terms and controlled vocabulary were developed. There are five chapters with twelve supporting appendixes. Chapter One presents an introduction to the problem and reviews the pilot study. Chapter Two presents the literature review and theoretical basis for the study. Chapter Three describes the research questions, hypotheses and methods. Chapter Four presents findings. Chapter Five presents a summary of the findings and their support of the hypotheses. Unanticipated findings, limitations, speculations, and areas of further research are indicated. Findings indicate that middle school users interact with the system in various sequences of patterns. ...

A theory for the measurement of Internet information retrieval.

A theory for the measurement of Internet information retrieval.

Date: May 1999
Creator: MacCall, Steven Leonard
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, information scientists are using quantitative measurement models for evaluating information retrieval performance that are based on the Cranfield model. This research modified this model by incorporating enduser relevance judgment rather than using objective relevance judgments, and by adopting a fundamental unit of measure developed for the cyberspace of Internet information retrieval rather than using recall and precision-type measures. The proposed measure, the Content-bearing Click (CBC) Ratio, was developed as a quantitative measure reflecting the performance of an Internet IR strategy. Since the hypertext "click" is common to many Internet IR strategies, it was chosen as the fundamental unit of measure rather than the "document." The CBC Ratio is a ratio of hypertext click counts that can be viewed as a false drop measure that determines ...

The gathering and use of information by fifth grade students with access to Palm® handhelds.

The gathering and use of information by fifth grade students with access to Palm® handhelds.

Date: December 2003
Creator: Peet, Martha Stuart Williamson
Description: Handheld computers may hold the possibility for a one-to-one computer: student ratio. The impact of the use of Palm® (Palm, Inc.) handhelds on information acquisition and use by 5th grade students in a North Texas school during a class research project was investigated. Five research questions were examined using observation, interviews, surveys, and document analysis. Are there differences in information gathering and use with the Palm between gifted, dyslexic, and regular learners? What relevance criteria do students use to evaluate a web site to determine whether to download the site to the Palm and afterwards whether to use the downloaded site's information in the report? How do the Palms affect the writing process? Do the animations and concept maps produced on the Palm demonstrate understanding of the intended concepts? Are there significant differences in results (i.e., final products grade) between Palm users and non-Palm users? Three groups of learners in the class, gifted, dyslexic, and regular learners, participated in the study. The regular and dyslexic students reported using Web sites that had not been downloaded to the Palm. Students reported several factors used to decide whether to download Web sites, but the predominant deciding factor was the amount of information. ...

Creator: Holmes, Jason
Description: Human auditory perception is suited to receiving and interpreting information from the environment but this knowledge has not been used extensively in designing computer-based information exploration tools. It is not known which aspects of sound are useful for accurately conveying information in an auditory display. An auditory display was created using PD, a graphical programming language used primarily to manipulate digital sound. The interface for the auditory display was a blank window. When the cursor is moved around in this window, the sound generated would changed based on the underlying data value at any given point. An experiment was conducted to determine which attribute of sound most accurately represents data values in an auditory display. The four attributes of sound tested were frequency-sine waveform, frequency-sawtooth waveform, loudness and tempo. 24 subjects were given the task of finding the highest data point using sound alone using each of the four sound treatments. Three dependent variables were measured: distance accuracy, numeric accuracy, and time on task. Repeated measures ANOVA procedures conducted on these variables did not rise to the level of statistical significance (α=.05). None of the sound treatments was more accurate than the other as representing the underlying data values. 52% ...

Accessing Information on the World Wide Web: Predicting Usage Based on Involvement

Accessing Information on the World Wide Web: Predicting Usage Based on Involvement

Date: May 2003
Creator: Langford, James David
Description: Advice for Web designers often includes an admonition to use short, scannable, bullet-pointed text, reflecting the common belief that browsing the Web most often involves scanning rather than reading. Literature from several disciplines focuses on the myriad combinations of factors related to online reading but studies of the users' interests and motivations appear to offer a more promising avenue for understanding how users utilize information on Web pages. This study utilized the modified Personal Involvement Inventory (PII), a ten-item instrument used primarily in the marketing and advertising fields, to measure interest and motivation toward a topic presented on the Web. Two sites were constructed from Reader's Digest Association, Inc. online articles and a program written to track students' use of the site. Behavior was measured by the initial choice of short versus longer versions of the main page, the number of pages visited and the amount of time spent on the site. Data were gathered from students at a small, private university in the southwest part of the United States to answer six hypotheses which posited that subjects with higher involvement in a topic presented on the Web and a more positive attitude toward the Web would tend to select ...

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.

Networked generation youth's information seeking process: An examination of cognitive, affective and physical behaviors and problem solving techniques.

Networked generation youth's information seeking process: An examination of cognitive, affective and physical behaviors and problem solving techniques.

Date: May 2008
Creator: Peterson, Janet Walker
Description: This study investigated the information seeking process of the networked generation youth. Specifically, I examined the cognitive, affective, and physical information seeking behaviors and problem solving techniques adolescent student users of the networked environment utilize to solve information needs. Grounded in the theoretical context of the information seeking process in the networked environment, the research extended the user-centered approach to modeling the information seeking process of networked generation youth. A mixed model research design was used to address the research questions. Phase 1 used an online questionnaire to solicit information from 125 students in Grades 7-12 regarding their understanding and use of networked environments, information seeking skills, and problem solving techniques. Phase 2 observed 12 students, two from each grade level, to gain an understanding into the information seeking process of networked generation youth. Participants completed information seeking scenarios of varying levels of complexity. As the participants completed the scenario, they engaged in talk-aloud verbal protocol to describe and explain their behaviors and techniques as they advanced through their information seeking process. Semi-structured interviews were conducted which provided an opportunity for the participants to clarify their information seeking experience. A profile of students' networked environment knowledge and use in relationship ...

Faculty use of the World Wide Web: Modeling information seeking behavior in a digital environment

Faculty use of the World Wide Web: Modeling information seeking behavior in a digital environment

Date: December 2000
Creator: Fortin, Maurice G.
Description: There has been a long history of studying library users and their information seeking behaviors and activities. Researchers developed models to better understand these information seeking behaviors and activities of users. Most of these models were developed before the onset of the Internet. This research project studied faculty members' use of and their information seeking behaviors and activities on the Internet at Angelo State University, a Master's I institution. Using both a quantitative and qualitative methodology, differences were found between tenured and tenure-track faculty members on the perceived value of the Internet to meet their research and classroom information needs. Similar differences were also found among faculty members in the broad discipline areas of the humanities, social sciences, and sciences. Tenure-track faculty members reported a higher average Internet use per week than tenured faculty members. Based on in-depth, semi-structured interviews with seven tenured and seven tenure-track faculty members, an Internet Information Seeking Activities Model was developed to describe the information seeking activities on the Internet by faculty members at Angelo State University. The model consisted of four basic stages of activities: "Gathering," "Validating," "Linking" with a sub-stage of "Re-validating," and "Monitoring." There were two parallel stages included in the model. ...

University Students and the Internet: Information Seeking Study

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Shamo, Esmaeel
Description: This study explored university students' information needs and seeking behaviors on the Internet. A Web-based survey was administrated one time. Two hundred responses were received from the target sample within the two weeks period of the study. Data were analyzed with descriptive statistics, factor analysis, and graphical representation. The study explored various issues related to the usability, preferences, and activities of the Internet, such as searching tools, e-mail, search engines, and preferred primary sources of everyday-life information needs. The study explored the perceptions of the students toward the Internet and the traditional library. Kuhlthau's model of the information-seeking process, which includes six stages and affective components, was utilized and modified in the construction of the Web survey. A study by Presno (1998), which includes the four types of Internet anxiety, was utilized in the construction of the Web survey. With regard to the six stages of Kuhlthau model, the majority of the respondents experienced stage 5, which was about information gathering; stage 3 had the next highest number of respondents. Very few respondents experienced stages 1 and 2. There was a systematic pattern in which, the earlier the stages the respondents were in, the more negative adjectives they selected, and ...
