The development of enhanced information retrieval strategies in undergraduates through the application of learning theory: an experimental study

Macpherson, Karen, n/a January 2002 (has links)
In this thesis, teaching and learning issues involved in end-user information retrieval from electronic databases are examined. A two-stage model of the information retrieval process, based on information processing theory, is proposed; and a framework for the teaching of information literacy is developed. The efficacy of cognitive psychology as a theoretical framework that enhances the understanding of a number of information retrieval issues, is discussed. These issues include: teaching strategies that can assist the development of conceptual knowledge of the information retrieval process; individual differences affecting information retrieval performance, particularly problemsolving ability; and expert and novice differences in search performance. The researcher investigated the impact of concept-based instruction on the development of information retrieval skills through the use of a two-stage experimental study conducted with undergraduates students at the University of Canberra, Australia. Phase 1 was conducted with 254 first-year undergraduates in 1997, with a 40 minute concept-based teaching module as the independent variable. A number of research questions were proposed: 1. Wdl type of instruction influence acquisition of knowledge of electronic database searching? 2. Will type of instruction influence information retrieval effectiveness? 3. Are problem-solving ability and information retrieval effectiveness related? 4. Are problem-solving ability and cognitive maturity related? 5. Are there any differences in the search behaviour of more effective and less effective searchers? Subjects completed a pre-test which measured knowledge of electronic databases, and problem-solving ability; and a post-test that measured changes in these abilities. Subjects in the experimental treatment were taught the 40 minute concept-based module, which incorporated teaching strateges grounded in leaming theory. The strategies included: the use of analogy; modelling; and the introduction of complexity. The aims of the module were to foster the development of a realistic concept of the information retrieval process; and to provide a problem-solving heuristic to guide subjects in their search strategy formulation. All subjects completed two post-tests: a survey that measured knowledge of search terminology and strategies; and an information retrieval assignment that measured effectiveness of search design and execution. Results suggested that using a concept-based approach is significantly more effective than using a traditional, skills-demonstration approach in the teaching of information retrieval. This effectiveness was both in terms of increasing knowledge of the search process; and in terms of improving search outcomes. Further, results suggested that search strategy formulation is significantly correlated with electronic database knowledge, and problemsolving ability; and that problem-solving ability and level of cognitive maturity may be related. Results supported the two-stage model of the information retrieval process suggested by the researcher as one possible construct of the thinking processes underlying information retrieval. These findings led to the implementation of Phase 2 of the research in 1999. Subjects were 68 second-year undergraduate students at the University of Canberra. In this Phase, concept-based teaching techniques were used to develop four modules covering a range of information literacy skills, including: critical thinking; information retrieval strategies; evaluation of sources; and determining relevance of articles. Results confirmed that subjects taught by methods based on leaming theory paradigms (the experimental treatment group), were better able to design effective searches than subjects who did not receive such instruction (the control treatment group). Further, results suggested that these teaching methods encouraged experimental group subjects to locate material from more credible sources than did control group subjects. These findings are of particular significance, given the increasing use of the unregulated intemet environment as an information source. Taking into account literature reviewed, and the results of Phases 1 and 2, a model of the information retrieval process is proposed. Finally, recognising the central importance of the acquisition of information literacy to student success at university, and to productive membership of the information society, a detailed framework for the teaching of information literacy in higher education is suggested.

Gymnasieelevers informationskompetens : En studie i sju klasser i gymnasiets år 3 / Information Literacy and Students in Secondary Education : a Study of Seven Upper Secondary School Classes

Lordh, Anneli January 2009 (has links)
<p>This master's thesis examines information literacy and students in secondary education. The study is framed within a sociocultural perspective of learning and the method used is questionnaires. The major question posed is how and where students seek information. Other questions are if the students critically evaluate and analyse in­formation sources and if teachers and school librarians cooperate with each other in order to help the students with their assignments.</p><p>The findings indicate that most students regard information seeking as fact-finding or finding the right an­swers to the question. Only one third of students experienced information seeking as seeking and using informa­tion for understanding a topic. The first place the students look for information is the Internet. Half of the stu­dents think they have been trained in information seeking. More boys than girls believe they have been trained. Three quarters of the students do not think they need more training in information seeking. Two thirds of the students think they have been sufficiently trained in source evaluation and more boys than girls believe they have been sufficiently trained. Just over half of the students do not think they need more training in source evaluation.</p><p>A good half of the students think the school library is quite important and almost half of the girls and one third of the boys visit the library once or twice per month. The cooperation between the teachers and the librari­ans does not work as well in the schools as the teachers and librarians wish but is improving. The majority of the teachers and librarians think their cooperation needs to be improved. The majority of the teachers think there is a correlation between information seeking and learning outcomes. All the librarians think the library is a resource that ought to be integrated in the students' education.</p><p>My conclusion is that the majority of the students are not information literate. To be information literate, the students need to have the ability to locate and evaluate the required information. Information seeking as scruti­nizing and analysing is a pre-requisite for lifelong learning.</p>

Finding techknowledgey : students' navigations of an institution's technological landscape

Dean, Allyson S. 26 April 2012 (has links)
This study explored how students navigate the technological landscape of a public, land-grant institution. Through online surveys and semi-structured, one-on-one interviews, the study operated through an anticipatory/participatory lens to research with the intent of understanding students' experiences with technology at a research institution. Using this methodology and Triandis and Triandis' (1960) Theory of Social Distance and Sanford's (1969) Theory of Challenge and Support as theoretical support, the study identified five themes regarding students' experiences with technology: (a) differences in students' perceived levels of technological fluency (b) institutional expectations of students' technological fluency, (c) variance in institutional training on educational technologies, (d) importance of personal computer ownership and Internet access, and (e) understanding individual technological needs. Coupled with the methodology, these findings serve to proffer institutional awareness and understanding of students' experiences of an institution's technological landscape. / Graduation date: 2012

The Discourse of the Information Age

Keenan, Andrew 06 1900 (has links)
This thesis examines the discourse of the information age and its influence on information literacy and social networking websites. The information age proposes that society has been dramatically changed by the recent advancements of information and information technology. The information age is a ubiquitous concept, manifesting specifically in two areas: library and information studies (LIS) and social networking websites. Information literacy, the American Library Associations education strategy for the information age, empowers library patrons with information skills to participate in the emerging era. Social networking websites (Facebook, MySpace, and Twitter) represent information- based businesses like those predicted by information age theorists. This thesis concludes that the arrival of the information age is impossible to discern, but the influence of information and information technology is significant.

Contradictions Between How Students Are Taught to Write And What They Are Expected To Read In General Education Courses

Kirk, Rachel Anne 01 May 2011 (has links)
This study explored the relationship between how students are taught to write in first-year English composition classes and what they are expected to read as part of the general education requirements at a publically-funded large university in the southeast (PLUS), and then to determine whether a gap exists. If a gap is found to exist between the preparation of students and their ability to read material that has been assigned by the teaching faculty, these students are less likely to be considered information literate by any rubric. This study uses a mixed-methods approach. Content analysis is employed to examine the assigned readings students encounter, and interviews are conducted to explore how students make sense of the academic writings assigned in general education classes. Research questions included (1) What are the overall structures of both (a) instruction composition and (b) scholarly journal articles assigned for reading in subsequent general education classes in the disciplines of psychology and history at PLUS? (2) How can these structures be identified? (3) What are the top-level structural patterns of composition within these two academic disciplines and how do they differ? and (4) Do these differences create contradictions in how students are taught to write in freshmen composition courses and the composition of the journal articles they are expected to read in their required general education classes? Thirty-one texts taken from general education syllabi were analyzed for incidence and placement of specific structural elements such as topic sentences and signal words. This study also explored perceptions of these differences from the standpoint of college students. Interviews of twenty-two students were conducted using Dervin’s Sense Making Methodology. These interviews were analyzed in terms of situations, gaps, bridges, outcomes, as well as thematic concepts that consistently arose during the interviews. Significant differences existed between readings from English Composition classes and assigned scholarly journal articles in history and psychology in incidence and placement of topic sentences, use of signal words or phrases, and readability. In addition, thematic analysis of the interviews of students found that they experienced gaps between their expectations of text composition and their experience reading assigned journal articles.

Information Seeking Behaviour of Generation Y Students at the Stellenbosch University Library and Information Service.

Adams, Lindall Elaine. January 2009 (has links)
<p>The project examines the information seeking behaviour of a small group of so-called Generation Y students at the Stellenbosch University as they undertake an academic&nbsp / assignment. There is consensus across the world that universities need to adapt to the needs of Generation Y students, brought up with high-level information technology, the internet and social networking. However, research shows that this does not mean that they are information literate. They have high-tech skills but often do not know how to analyse an information need or discriminate between information sources. Information scientist Carol Kuhlthau develop the ISP model upon which the study was based. Her model sees information seeking as a complex cognitive and affective process. Successful seekers have learned how to manage the process. University libraries need to adapt their information retrieval systems and services to meet the needs of their new kinds of students. The study, a small-scale intensive qualitative case study, hopes to provide insight into how they might do this. The researcher collected data while the participants were writing the assignment. Data gathering methods included interviews, journal writings and questionnaires.</p>

Readers Matter: The Development of an Individualized Professional Development Model

Super, Daniel Jacob 01 May 2011 (has links)
An alarming trend of student non-compliance with reading assignments in secondary and post-secondary environments is causing concern in many areas, including college readiness. Public school teachers and university faculty alike are responsible for the literacy levels of graduating students; however, many educators are not implementing the adequate literacy supports within their content area courses. This project used current research on best practice in literacy instruction, as well as the Characteristics of Highly Effective Teaching and Learning to create the Readers Matter™ evaluative process in which faculty members self-select to be assessed regarding the current levels of student literacy support. After scoring the assessment, evaluators are then able to provide individualized professional development targeting areas of weakness made evident by the Readers Matter™ rubric. The current study evaluated five university instructors at a midsized university in the south-central United States. The results of this preliminary development research identified the data collection procedures that were beneficial and ultimately informative in the evaluation process and enabled developers to make informed decisions regarding individualized professional development.

Representing information use in an educational setting

Cameron, Tamara 05 1900 (has links)
The purpose of this study is to describe how a high school student retrieves information in order to write a history research paper, and to investigate the role genre plays in this process of search and paper construction. This study interrogates the conditions under which students are sent to the library to complete research assignments. What is absent from the research of school library use is how the kinds of knowledge expected from the students, and how the kinds of uses and manipulations that information is to be put through are connected to the access and retrieval of information. Because use is the final stage in the information process, this problem is approached by examining the assumptions about language, knowledge, and genre that teachers and students bring to research assignments in the school library. Rhetorical genre theory may be used to construct a representation of information use within an educational setting. Rhetorical genre theory will also be used to determine the method of analysis. By examining a few instances of high school history research, we can begin to systematize the features found beyond the sample to a larger study. An interdisciplinary approach that integrates classification theory, information seeking behavior, and rhetorical practices may help to characterize effective models in information retrieval. This model may provide a structure for understanding how a core set of research tasks utilizes a certain set of genres.

In Google we trust : The information-seeking behaviour of Swedish upper secondary school students

Zunko, Jenny January 2011 (has links)
This study uses focus groups and a questionnaire to examine the information-seeking behaviours of Swedish upper secondary school students. Focus group interviews were conducted among students aged 17-20 at four Swedish upper secondary schools in two different cities. The interviews focused on how the informants themselves experienced their information seeking. In addition, a survey focused on the opinions of upper secondary school teachers regarding the source use of their students. The research questions considered were: What kind of information-seeking behaviour characterizes Swedish upper secondary school students? What kind of information do Swedish upper secondary school students seek when it comes to issues where corporations can be of assistance? How do Swedish upper secondary school students prefer to have information presented? The results of the study provided some valuable insights concerning these questions. The students turned out to use the Internet, and most often Google, in much of their information seeking. However, human contact in the form of face-to-face conversations or presentations was also considered highly important. Furthermore, the information-seeking skills, or information literacy, of secondary school students are not emphasized in their education. The study was performed in cooperation with AstraZeneca in the hope of the results providing the company with valuable information regarding one of their intended target groups.

Informationskompetens : En fenomenografisk undersökning av skolledares uppfattningar om informationskompetens

Olsson, Therese January 2012 (has links)
The aim of my “two years master thesis” was to examine school administrators perceptions about important information literacy skills that the students should be able to control, perceptions about what role the teachers and the librarians have in teaching students information literacy and perceptions about the collaboration between these groups. My questions have been: Have the school administrators reflected upon the conception of information literacy? What conceptions do school administrators have about important information literacy skills that the students should be able to control? What role do they consider the teachers and the librarians to have in making all students information literate? How do they consider the collaboration between the teachers and the librarians work? What role do they consider themselves to have on a management level to make all students’ information literate? I used a phenomenographical method and carried out six qualitative interviews with school administrators from five senior high schools in the municipality of Gävle. Both public schools and independent schools were included in the study.   Most of the school administrators considered information literacy to be the same as criticism of sources, which they also considered as one of the most important information literacy skills. Only one of the school administrators thought that information literacy is about arranging the information. All of the school administrators thought that the teachers have the main responsibility for the education in information literacy. The  librarians were by the school administrators considered not to be used at their full potential and the perceptions about the librarians tasks was that they were to be a guidance in databases, tempt students in to reading by talking about books and ask students critical questions through the information literacy process. The school administrators thought that the collaboration between the teachers and the librarians was satisfying. All of the school administrators thought that they should provide the right conditions for collaboration between the groups, but that the school administrators should not run the project. One of the reasons why the school administrators in my essay focused on criticism of the sources and not on the arranging of information can be due to that information literacy is vaguely described in the school curriculum. A conclusion in the study is that the school administrators have insufficient knowledge and insight in how the collaboration between the teachers and the librarians work and that the school administrators do not allocate enough time for the teachers and librarians to collaborate.
