Background: Interrupted time series (ITS) studies contribute importantly to systematic reviews of population-level interventions. We aimed to develop and validate search filters to retrieve ITS studies in MEDLINE and PubMed. Methods: A total of 1017 known ITS studies (published 2013-2017) were analysed using text mining to generate candidate…

Metacognitive judgment of one's online search process (calibration) is an important element of searching efficiency. This study investigated Chinese university students' calibration during online information search. Fourteen students s were asked to search answers for three assigned tasks. Immediately after the search, all participants attended…

The number of American adults who use electronic nicotine delivery systems (ENDS) increased by 3 million people in 2018, up 38.3% from 8.1 to 11.2 million. Search data for ENDS were analyzed against relevant traits including state longitude, tobacco tax rate and national tobacco program funding. Searches increased 88% (95% CI, 70-100) over the…

Search-as-learning research has emphasized the need to better support searchers when learning about complex topics online. Prior work in the learning sciences has shown that effective self-regulated learning (SRL), in which goals are a central function, is critical to improving learning outcomes. This dissertation investigates the influence of…

Systematic literature reviews are common in social research for integrating and synthesising existing research. This paper argues that the outcomes of such reviews are affected by the choice of bibliographic databases. It presents evidence of substantial variation across three large electronic databases (Scopus, Web of Science and EBSCO) in a…

While geographic search filters exist, few of them are validated and there are currently none that focus on Germany. We aimed to develop and validate a highly sensitive geographic search filter for MEDLINE (PubMed) that identifies studies about Germany. First, using the relative recall method, we created a gold standard set of studies about…

With the rapid development of information technologies, online learning platforms have become the most convenient way for users(teachers and learners) to share their learning content. However, due to the increasing number of educational content, it becomes very difficult for learners to find the most appropriate items. Most previous methods…

This article discusses a quest-based approach to teaching catalog skills and getting to learn more about students reading interests. Quest-based activities are meaningful and can be quite engaging, not to mention entertaining and stimulating (Snelson 2022). They provide choice and differentiate the learning experience, as well as multiple pathways…

Using pre- and post- intervention data, this formative study explores instructional moves designed to guide students' critical thinking as they engage in lateral reading and digital source evaluation. Working in a dual enrollment composition classroom, researchers identified and addressed three areas of need: considering context when determining…

Lifelong learning (LLL) has gained an important place in the agendas of national and international organizations and the education policies of countries with globalization and digitalization in education. Even though there is a large body of research regarding lifelong learning tendency, web pedagogical content knowledge, attitude towards…

Several studies have explored the effects of cognitive tools, such as scaffolding, on the quality of argumentation in online argumentation activities. However, although information searching is the most popular online activity, few studies have investigated the roles of online information resources in the quality of argumentation. This study…

The Systematic Review Toolbox aims provide a web-based catalogue of tools that support various tasks within the systematic review and wider evidence synthesis process. Identifying publications surrounding specific systematic review tools is currently challenging, leading to a high screening burden for few eligible records. We aimed to develop a…

Introduction: Recently, the problem of diversification of search results has attracted a lot of attention in the information retrieval and Web search research community. For multi-faceted or ambiguous queries, a search engine is generally favoured if it is able to identify relevant documents on a wider range of different aspects. Method: We…

A retrospective analysis published by the German Institute for Quality and Efficiency in Health Care (IQWiG) in 2018 concluded that no filter for non-randomized studies (NRS) achieved sufficient sensitivity ([greater than or equal to] 92%), a precondition for comprehensive information retrieval. New NRS filters are therefore required, taking into…

This study explored expertise in searching for online information on a contentious historical and political question. Fact checkers, historians, and college students thought aloud while conducting online research on the question, "Did Margaret Sanger, the founder of Planned Parenthood, support euthanasia?" Analyses of screen recordings…
