GradeCam transforms cameras into quick test scanners
GradeCam is a next-generation data-collection solution that allows you to use Webcams and
other types of cameras to scan multiple-choice tests and collect data for use in teaching.
The software is an image-recognition application which, when used in conjunction with
Web cameras or document cameras, provides an alternative to far more expensive test
scanning machines known as optical mark readers, or OMRs.
The software also allows instructors to use the technology at the classroom level, where
teachers can scan tests immediately and discuss the results right away.
Using GradeCam, teachers can know each student’s score immediately, and get an overall
sense of how the class performed on each question and section. This allows the teacher to
review the test with the students right away and explain points that appear unclear to the class
as a whole when everything is still fresh in their minds.
Kindle 2 Reading just got better
When Kindle was first introduced, it revolutionized reading with its portable ultra-thin design which allowed reading aficionados to purchase and read within a minute their favorite literature without the need for a computer. Kindle 2, which was launched in February 2009, builds on that experience by adding several new features that make reading even more pleasurable. The new innovations include a 6-inch E-Ink electronic paper display that provides a 600 x 800 pixel resolution at 167 ppi, 16-level grayscale. Furthermore, measuring just 8 x 5.3 x 0.36 inches, the new device is even slimmer then the first Kindle and weighs around 10.2 ounces The controls have also been upgraded, with Kindle 2 featuring a redesigned keyboard, and a five-way control button, which can be used either for browsing through the pages of the books or magazines one is reading or for simply accessing the device’s various options. Kindle 2 also provides a built-in New Oxford American Dictionary for those words whose meanings simply elude you. Users can even search for specific words or phrases on Wikipedia, as well as the entire Internet. With the Whispersync technology, users can also seamlessly switch back and forth between their several Kindle devices while keeping the reading location synchronized.
Therefore, whether they’re reading off the Kindle 2 or a mobile phone, they can simply pick up reading right where they left off. Kindle 2 also offers increased storage space, sporting 2GB of memory which can store up to 1500 eBooks), while the battery life allows eBook readers with up to four days of reading after a single charge. Furthermore, with the wireless module switched off, the battery life will show a marked increase. The Kindle 2 provides an extensive file compatibility list, including Kindle (AZW), TXT, Audible (formats 4, Audible Enhanced (AAX)), MP3, unprotected MOBI, PRC natively; PDF, HTML, DOC, JPEG, GIF, PNG, BMP through conversion. And if you’re wondering what’s with the Audible and MP3 formats, we must inform you that the new Kindle actually comes packed with built-in stereo speakers and text-to-speech technology, the device being actually able to “read” audio books to the user.
