We developed "metadta," a flexible, robust, and user-friendly statistical procedure that fuses established and innovative statistical methods for meta-analysis, meta-regression, and network meta-analysis of diagnostic test accuracy studies in Stata. Using data from published meta-analyses, we validate "metadta" by comparing and…

This article introduces the CELI corpus, a new learner corpus of written Italian consisting of ca. 600,000 tokens, evenly distributed among CEFR (Common European Framework of Reference for Languages) proficiency levels B1, B2, C1 and C2. The collected texts derive from the language certification exams administered by the University for Foreigners…

Users of digital language archives face a number of barriers when trying to discover and reuse the materials preserved in the digital collections created by current language documentation projects. These barriers include sparse descriptive metadata throughout many collections and the prevalence of audio-video materials that are impervious to…

As libraries respond to new teaching and research practices in the twenty-first century, it is important to consider how to advertise library services. Users are often surprised to learn about the varied expertise of library staff and the many services the staff provides. To investigate this issue, the author designed a study to identify a more…

This supplement contains documentation on the explicit and implicit stratification variables included in the TIMSS 2011 data files. The explicit strata are smaller sampling frames, created from the national sampling frames, from which national samples of schools were drawn. The implicit strata are nested within the explicit strata, and were used…

A number of international initiatives, such as the Open Educational Resources initiative, have recognized the potential value of sharing and reusing digital resources among educational communities. As a result, organizing, offering, and accessing these resources over the web have been key issues for both the research and the educational community.…

When staff at the Wisconsin State Law Library began compiling a wish list for a new website, the topic of a new domain name came up almost immediately. Their old website was located at http://wsll.state.wi.us. Spelling that relatively complex domain over the phone day after day provided the impetus to explore other options. Whatever domain name…

In response to the rapid development of digital libraries over the past decade, researchers have focused on the use of metadata as an effective means to support resource discovery within online repositories. With the increasing involvement of libraries in digitization projects and the growing number of institutional repositories, it is anticipated…

Accessibility is one of the key checkpoints in all software products, applications, and Web sites. Accessibility with digital images has always been a major challenge for the industry. Images form an integral part of certain type of documents and most Web 2.0-compliant Web sites. Individuals challenged with blindness and many dyslexics only make…

Recent developments in the standardisation of learning technology have resulted in models of learning activities and resources including descriptive metadata and definitions of conditional flows for multirole activities. Nonetheless, such "learning designs" are actually representations of the "results" of the design process and do not provide…

The Dublin Core metadata community and the INDECS/DOI community of authors, rights holders, and publishers are seeking common ground in the expression of metadata for information resources. An open "Schema Harmonization" working group has been established to identify a common framework to support interoperability among these communities.…

Examines the traditional, historical applications of abstracts and summary notes by individual authors in typical databases in order to assess and develop applications for Internet information retrieval. Highlights include information seeking; guidelines for writers; models of abstracts and summary notes; metadata; and Internet standards,…

This guide provides practical suggestions and tips for authors of learning objects (defined as any grouping of materials that is structured in a meaningful way and is tied to an educational objective), offering advice for design, usability, and reusability; for keeping learning objects learner-centered and learner-driven; for aligning with current…

Educational institutions across the country are adopting guidelines to help assure the quality of e-learning programs and courses. Corporations are also adopting guidelines, but their focus is on the interoperability and reusability of learning objects. While there are commonalities, there are also significant differences between how education and…

This paper provides a comprehensive set of guidelines for building an online course based on the e-learning standards. It discusses the steps that should be followed to build a digital repository that facilitates the storage, retrieval, and reuse of the learning resources that comprise an online course in a standard way. The paper also examines…
