In this paper, we introduce a performance-based test for measuring adolescents' competences in online inquiry. The test covers four competence dimensions: 1) searching and selecting relevant sources, 2) identifying the main ideas presented in the sources, 3) evaluating the credibility of the sources, and 4) synthesizing information across the sources. We implement a technological solution called NEURONE to carry out this routine. The scoring of the test data is demonstrated by presenting preliminary results of a case study. Finally, we discuss the strengths and limitations of the test.
This poster presents preliminary results from a user study designed to evaluate the feasibility to use a low-cost EEG sensor in the identification of information relevance as perceived by users. The study involved 10 participants, both graduate and undergraduate students, performing a selfmotivated exploratory search task contextualized on the literature review for their own thesis work. The study design comprised two stages that focus on (1) snippets collection and (2) explicit relevance assessments. In both stages, participants wore a low-cost electroencephalography (EEG) sensor that provides measures related to two mental states (i.e. attention and meditation). Analyses focused on comparing the presence and intensity of these mental states in the set of pages (both relevant and non-relevant) classified by the users themselves. Results showed that attention levels and blink intensity in relevant pages are significantly higher than in non-relevant ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
