Although widely used, the SCORM metadata model for content aggregation is difficult to be used by educators, content developers and instructional designers. Particularly, the identification of contents related with each other, in large repositories, and their aggregation using metadata as defined in SCORM, has been demanding efforts of computer…

This research improves the precision of information extraction from free-form text via the use of cognitive-based approaches to natural language processing (NLP). Cognitive-based approaches are an important, and relatively new, area of research in NLP and search, as well as linguistics. Cognitive approaches enable significant improvements in both…

This study reports on a survey of students in information sciences designed to test differences related to e-book formats and other factors. The results from 161 respondents suggest that strategic decision-making shapes use of different e-book and print format options for users who already have significant exposure to e-books. These format options…

Coding, the analytic task of assigning codes to nonnumeric data, is foundational to writing research. A rich discussion of methodological pluralism has established the foundational importance of systematicity in the task of coding, but less attention has been paid to the equally important commitment to language complexity. Addressing the interplay…

There is ample evidence that language learning strategies improve learners' outcomes. This is also the case in vocabulary learning. However, little attention has been given to students' language learning strategy knowledge. This experimental study assessed the extent to which keyword method (KWM) explicit instruction resulted in students' explicit…

In order to explore the development of research of science teacher(RST), 904 articles from the Web of Science (WoS) core set based on bibliometric methods through R software were analyzed in this research. Specifically, it examined the co-occurrence relations of countries/regions, major journals, most cited references, and hot keywords from the…

The progress of technology in the field of education has led to the development of new professional skills in the teaching community, such as digital competence. Likewise, it has propagated the appearance of new learning environments mediated by technological resources that favor the generation of a large volume of data, known as Big Data, derived…

Discussion forums in learning management systems (LMS) have been shown to promote student interaction and contribute to the collaborative practice in the teaching-learning process. By evaluating the postings, teachers can identify students with learning difficulties. However, due to the large volume of posts that are generated on a daily basis in…

This case study aims to explore how high-achievers search the web for two different task types: easy vs. difficult. It took place in a science high school accepting students according to national exam scores. 10 voluntary students participated in the sessions. They were assigned two tasks with no time limitation. Screens were recorded and a…

In this study, we review 1830 research articles on artificial intelligence in education (AIED), with the aim of providing a holistic picture of the knowledge evolution in this interdisciplinary research field from 2010 to 2019. A novel three-step approach in the analysis of the keyword co-occurrence networks (KCN) is proposed to identify the…

Data mining methods for classification and regression are becoming increasingly popular in various scientific fields. However, these methods have not been explored much in educational measurement. This module first provides a review, which should be accessible to a wide audience in education measurement, of some of these methods. The module then…

Web-scale discovery services such as Summon (Serial Solutions), WorldCat Local (OCLC), EDS (EBSCO), and Primo (Ex Libris) are often touted as a single search solution to connect users to library-owned and -licensed content, improving discoverability and retrieval of resources. Assessing how well these systems achieve this goal can be challenging,…

In this paper, the BBC's stance on English language use is investigated by analysing its language guidelines provided in the 2003 BBC "News Styleguide." Before the analysis is tackled, a brief discussion of the use of language and style guides in the media is given to illustrate its complexities and effects on news providers. In order to…

Information used to assist biomedical and clinical research has largely comprised of data available in published sources like scientific papers and journals, or in clinical sources like patient health records, lab reports and discharge summaries. Information from such sources, though extensive and organized, is often not readily available due to…

Introduction: Despite the popularity of crowdsourcing, the reliability of crowdsourced output has been questioned since crowdsourced workers display varied degrees of attention, ability and accuracy. It is important, therefore, to understand the factors that affect the reliability of crowdsourcing. In the context of producing relevance judgments,…
