The heterogeneous data acquired by educational institutes about students' careers (e.g., performance scores, course preferences, attendance record, demographics, etc.) has been a source of investigation for Educational Data Mining (EDM) researchers for over two decades. EDM researchers have primarily focused on course-specific data analyses of…

Online learning has been widely discussed in education research, and open educational resources have become an increasingly popular way to help learners acquire knowledge. However, these resources contain massive amounts of information, making it difficult for learners to identify Web articles that refer to computer science knowledge. This study…

Introduction: Studies have indicated that users' text highlighting behaviour can be further manipulated to improve the relevance of retrieved results. This article reports on a study that examined users' text highlight frequency, length and users' copy-paste actions. Method: A binary voting mechanism was employed to determine the weights for the…

A central issue in the design of curricula for all school levels is the development of the learners' high-order thinking skills and metacognitive skills. Among such required skills is the ability to solve problems. The literature dealing with the development of problem-solving skills is vast and primarily addresses the scientific disciplines, even…

ESP textbook plays an important role in facilitating students to develop their profession-related language skills. However, ESP textbooks published in China are less developed and often criticized as ignoring the training of language skills. This research aims to reveal the specific problems of China's ESP textbooks by conducting a multiple-case…

Inquiry-Based Learning (IBL) is an effective approach for promoting active learning. When inquiry-based learning is incorporated into instruction, teachers provide guiding questions for students to actively explore the required knowledge in order to solve the problems. Although the World Wide Web (WWW) is a rich knowledge resource for students to…

This study evaluates the effectiveness of simple and expert searches in Google Scholar (GS), EconLit, GEOBASE, PAIS, POPLINE, PubMed, Social Sciences Citation Index, Social Sciences Full Text, and Sociological Abstracts. It assesses the recall and precision of 32 searches in the field of later-life migration: nine simple keyword searches and 23…

A study of 24 scientific articles in the South African Computer Journal compared four term-weighting schemes for detecting information-rich passages in texts. Results demonstrated that word categories and frequency-derived weights were closely correlated but that weighting according to first mention theory (cue-method) and frequency-based weights…

Describes the selection policies, subject access, search aids, indexing, coverage, and currency of three online databases in the fields of electronics and computer science: COMPENDEX, ELCOM, and INSPEC. Sample searches are displayed for each database. A bibliography cites five references. (FM)

Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

Discusses software developed to organize and retrieve electronically stored data, examining structure of the databases in which information is stored and the physical structure of the storage medium. Hierarchical and relational databases, unordered files, B-trees, and storage/software for specific purposes (such as weather, stock market, and…

Surveys the technology of database software and hardware, describing some of the principal issues related to the user's view of data, sharing, concurrent access, security, and integrity. (JN)

Cherry Creek (Colorado) and Los Angeles (California) school districts are using microcomputers linked to central computers to process student data. (Author)

By drawing an analogy to computer programming, it is apparent that end user training for online bibliographic search systems will increase, lead to vastly increased use of online search systems, increase the understanding of end users, and reduce the amount of time professionals spend on routine tasks.
