Turnitin is an effective online technology for improving student writing. It is used by educators worldwide (over 60 million papers were processed in 2011) to check students' papers for originality, to enable web-based peer review and for digital grading of student work.
Its most used and famous feature is OriginalityCheck, the plagiarism prevention tool. It ensures original work by checking submitted papers against billions of web pages, millions of student papers and leading library databases and publications. Originality Reports provide a summary of matching or highly similar text found in a submitted paper.
Another important tool, GradeMark, allows an instructor to edit and grade student papers online. The instructor can add comments within the body of the paper, point out grammar and punctuation mistakes, evaluate the paper against qualitative or quantitative rubrics, etc.
A third tool is PeerMark: Instructors can create and manage PeerMark assignments that allow students to read, review, and evaluate one or many papers submitted by their classmates.
Turnitin integrates with more than 50 Course Management Systems, including Blackboard, Moodle, Instructure Canvas, Desire2Learn, Pearson Learning Studio, and Sakai.
amara (powered by Universal Subtitling)
amara (formerly known as Universal Subtitles) is a community platform that allows for easily captionning and translating of the videos one produces, by seeking assistance from the viewers. Subtitling not only increases the geographical appleal of the vides by adding language versions, but also has the additional advantage of making videos accessible for the deaf and hard-of-hearing. The subtitling (translation and subtitle text addition) is done by volunteering viewers, like a wiki: easy, free and fast with no software to install. As of today August 15 2011) over 117000 videos have already been subtitled with Universal Subtitles.
Amara gives individuals, communities, and larger organizations the power to overcome accessibility and language barriers for online video. The tools are free and open source and make the work of subtitling and translating video simpler, more appealing, and, most of all, more collaborative.
The benefits of captioning and subtitling are immense:
- Captions make videos accessible for viewers who are deaf or hard of hearing
- Translations make it possible for all of us to watch video in languages that we don't speak
- Video creators get: better SEO, more views, access to a far bigger (potentially multilingual and global) audience, accessibility for deaf and hard of hearing viewers, and more
Amara is composed of three main parts:
- A subtitle creation and viewing tool (aka the widget)
- A collaborative subtitling website
- An open protocol for subtitle search/delivery

Eyes on the Skies
Eyes on the Skies consists of a 60-minute DVD and a 132-page, full-colour book, exploring the development of the telescope over the four centuries following Galileo's breakthrough, along with all the astronomical riches this instrument has revealed. The DVD gathers animations, simulations and stunning photographs, displaying the heavens revealed by astronomers while the film's host and narrator explain these unveiled cosmic answers, as well as pointing out areas of continuing mystery. Rounding out the Eyes on the Skies package is a sturdy, hardcover textbook that complements the film, creating a comprehensive educational experience.
Eyes on the Skies, by telling the history of the telescope in astronomy, aims to offer a compelling perspective on how human knowledge of space and our place in it has been completely revolutionised in the last 400 years. The Universe is a vast, complex, mind-boggling realm; showing science's step-wise visual foray into the final frontier will help make astronomy much more accessible and "real" to students of most ages. The DVD runs for 60 minutes and contains subtitles in several languages. The Eyes on the Skies book is available in English, German, Finnish, Korean and Japanese. DVD and chapter excerpts, along with beautiful photographs are also freely available to the general public, teachers and students worldwide.
The Eyes on the Skies movie is presented by Dr. J aka Dr. Joe Liske from European Southern Observatory (ESO - http://www.eso.org/public), and the authors are Govert Schilling (Alles over Sterrenkunde, the Netherlands - http://allesoversterrenkunde.nl) and Lars Lindberg Christensen (European Space Agency (ESA) - http://www.esa.int/esaCP/index.html and ESO, Germany), who strive to contribute to the popularisation of science and technology.
