Exploration and exploitation in complex search
tasks: How feedback influences whether and
where human agents search
Exploration and exploitation in strategic decision-making entail decisions about whether and where to search for new alternatives to improve the status quo. Prior research has not explored how decisions about whether to continue search (vs. stop search or satisfice) and where to search (near vs. far) are interrelated. We report laboratory experiment results on how individuals decide whether and where to search in a complex, combinatorial task. We find that different feedback variables influence the decision to stop search from decisions regarding how broadly to search. Our results suggest that not accounting for the decision to continue (or stop) searching, separately from breadth of search, can lead to incorrect predictions regarding how feedback influences search behavior.
Online Information Search Performance and Search Strategies in a Health Problem-Solving Scenario
Although access to Internet health information
can be beneficial, solving complex health-related problems online is challenging for many individuals. In this
study, we investigated the performance of a sample of
60 adults ages 18 to 85 years in using the Internet to
resolve a relatively complex health information problem. The impact of age, Internet experience, and cognitive abilities on measures of search time, amount of search, and search accuracy was examined, and a model of Internet information seeking was developed to guide the characterization of participants’ search strategies. Internet experience was found to have no impact on performance measures. Older participants exhibited longer search times and lower amounts of search but similar search accuracy performance as their younger counterparts. Overall, greater search accuracy was related to an increased amount of search but not to increased search duration and was primarily attributable to higher cognitive abilities, such as processing speed, reasoning ability, and executive function. There was a tendency for those who were younger, had greater Internet experience, and had higher cognitive abilities to use a bottom-up (i.e., analytic) search strategy, although use of a top-down (i.e., browsing) strategy was not necessarily unsuccessful. Implications of the findings for future studies and design interventions are discussed.
Combating Fake News with Digital Identity Verification
The Internet has become a fundamental source of information exchange in the 21st century. In particular, online social media platforms are becoming increasingly important tools for communication and political discourse in the United States and abroad. This medium presents a novel, unprecedented way for people to become more informed and civically involved, but simultaneously opens democratic societies up to potential interference by foreign, malevolent actors who manipulate the information that social media users consume and use to make decisions. As an example of social media influencing the opinions and actions of U.S. residents, foreign Russian actors were able to organize a protest and a simultaneous counter-protest in Houston, Texas during the 2016 U.S. presidential election campaign using Facebook groups operated by a Kremlin-linked troll farm from Saint Petersburg.1 Other instances of foreign influences include individuals abroad selling American political advertisements for monetary gain, social bots being used to give the false impression of grassroots public support, and in general, the rapid spread of false, sensational media. Given the ubiquitous role that online platforms play in shaping socio-political discourse and outcomes, we propose a government-supported approach for combating the spread of fake news online by verifying the identities of U.S. residents on social media platforms.
Information literacy in the workplace
Information literacy has been a subject of interest for academic librarians for nearly thirty years, however special librarians have written comparatively little on the topic of information literacy in the workplace. It is an important issue as it provides an opportunity for special librarians to enhance their role in their organisation. This paper discusses the need for training in information literacy in the workplace and highlights the latest research and studies being undertaken in the field.
Reframing Information Literacy as a Metaliteracy
Social media environments and online communities are innovative collaborative technologies that challenge traditional definitions of information literacy. Metaliteracy is an overarching and self-referential framework that integrates emerging technologies and unifies multiple literacy types. This redefinition of information literacy expands the scope of generally understood information competencies and places a particular emphasis on producing and sharing information in participatory digital environments
Identifying Threshold Concepts for Information
Literacy: A Delphi Study
This study used the Delphi method to engage expert practitioners on the topic of threshold concepts—core ideas and processes in a discipline that students need to grasp in order to progress in their learning, but that are often unspoken or unrecognized by expert practitioners—for information literacy. A panel of experts considered two questions:
First, is the threshold concept approach useful
for information literacy instruction? The panel unanimously agreed that the threshold concept
The approach holds potential for information literacy instruction. Second, what are the threshold concepts for information literacy instruction? The panel proposed and discussed over 50 potential threshold concepts, finally settling on six information literacy threshold concepts.
The Concept of Information Literacy in Policy-Making Texts: An Imperialistic Project?
Organizations such as the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Federation of Library Associations (IFLA) put a lot of effort in advocacy and policy making for information literacy (IL). Their ambition to foster IL can be seen as a part of a multinational educational project. By exporting a Western IL model focused on textual information sources and the use of information and communication technologies (ICTs) into non-Western contexts that to a great extent lack ICTs, the educational project for IL runs the risk of turning into an imperialistic project. A discursively oriented analysis of two prominent policy documents discussed in the light of the so-called new imperialism and the idea of invisible technologies—indicates a standardized onesize-fits-all-model of IL. Through establishing a close contact between the policy-making strand and the research strand in the IL literature and by adhering to the broad concept of information literacies, the risk of imperialism and oppression might lessen.
Six Frames for Information literacy Education: a conceptual framework for interpreting the relationships between theory and practice
Information literacy educators are daily challenged by an environment in which colleagues and students bring very different perspectives to curriculum design, teaching and learning, and by the need to apply theories of learning to information literacy education in coherent ways. The purpose of this
paper is to propose a model, Six Frames for Information Literacy Education, as a tool for analysing, interpreting and understanding these challenges; and to explain the relational frame in more detail. In the first part of this paper we provide an overview of the different ways in which teaching, learning, and information literacy may be approached. We also introduce the Six Frames for information literacy education. In the second part, we explore some challenges and techniques of applying the relational
frame for information literacy education in more detail. Finally, we suggest some ways in which using the six frames may assist practice.
Troublesome Concepts and Information Literacy: Investigating Threshold Concepts for IL Instruction
Librarians regularly encounter students who struggle to understand and apply information literacy concepts. A qualitative survey administered to information literacy practitioners asked about troublesome content and analyzed results using the threshold concepts pedagogical framework first described by Jan Meyer and Ray Land. A threshold concept transforms the learner’s view of content and helps integrate previously learned material; threshold concepts are portals that, once traversed, bring insight into how to think and act like a practitioner within a discipline. This project uses the data collected to propose seven threshold concepts for information literacy.
Information Literacy and Critical Thinking: Different
concepts, shared conceptions.
Introduction. Information literacy and critical thinking are discussed as distinct concepts by authors in different disciplines. This paper seeks to analyse their conceptions to determine the extent to which they overlap, and identify areas for collaboration across disciplinary lines. Method. A hermeneutic literature review was conducted, followed by a content analysis of information literacy papers discussing content evaluation, and critical thinking papers from
key authors. Analysis. Proportions of identified themes represented within the two groups of papers were compared. Similarities and differences were assessed in conjunction with findings from the hermeneutic literature review. Results. Though divergent in their basic underpinning skills, critical thinking and information literacy conceptions pertaining to content evaluation were found to be strongly overlapping in their broader conceptions. Modern pressures giving rise to content evaluation concerns such as the ‘fake news’ phenomenon suggest a need for strong sense conceptions, and an avenue for integration between information literacy and critical thinking when evaluating information. Conclusion. Taken in their strong sense, information literacy and critical thinking conceptions show a high degree of overlap. Engagement across disciplinary lines could offer an enrichment to both concepts
Digital competence and information literacy: clarifying
concepts based on a literature review
This study aimed to collect input for the definition of
a conceptual framework of digital competence for information literacy to be developed in the context of doctoral programs in Education. A systematic literature review methodology was adopted, and several steps were developed that included: preliminary readings and initial mapping, which allowed to define the search terms and expressions; the definition of inclusion and exclusion criteria; the research in databases and aggregators; the pre-selection of articles; and the selection of the corpus of analysis, which included seven articles published in scientific journals with peer review. The studies are mainly focused on information literacy. The two concepts are addressed simultaneously in only three articles. Digital competence is related to the mastery of digital tools, namely to search for information in databases or to define alert strategies. We infer that this competence seems to be closer to more operative concepts, such as digital skills. Information literacy requires the effective use of information involving information search, selection, evaluation and communication. We conclude that it is necessary to crossreference and triangulate existing studies in order to define the digital competences for information literacy that doctoral students in Education should develop. This is the object of an ongoing doctoral project.
Dangers and Opportunities: A Conceptual Map of Information Literacy Assessment Approaches
The culture of assessment in higher education requires academic librarians to demonstrate the impact of information literacy instruction on student learning. As a result, many librarians seek to gain knowledge about the information literacy assessment approaches available to them. This article identifies three major assessment approaches: (1) fixed-choice tests, (2) performance assessments, and (3) rubrics. It maps the theoretical and educational assumptions on which these options are grounded and charts the dangers and opportunities of each assessment approach.
