OpenBazaar team here; we're creating a decentralized marketplace for your decentralized currency, Ask Us Anything! Students, faculty reflect on a year with Trunk Published: Friday, April 20, 2012 Updated: Friday, April 20, 2012 10:04 Trunk.tufts.edu In its inaugural year, Trunk has received mixed reviews from students and faculty. When students returned to the Hill in September, they encountered the newest member of the Tufts community — not University President Anthony Monaco, but Trunk. University Information Technology (UIT) announced in October 2010 its selection of of the open−source platform Sakai to replace Blackboard as its new LMS. Director of Educational and Scholarly Technology Services Gina Siesing said that the decision came after years of planning. “Blackboard was an end−of−life product, so we knew we had to replace it,” Siesing said. She added that the decision to go with an open−source system came from looking at salient trends in educational technology. “We really looked toward peer institutions to see what they were using,” Siesing said. Sophomore Amelia Cohen said that Trunk’s interface could be improved. “I love Trunk.

Share Student Work with Three Ring I love showing examples when explaining a new project or assignment for my students. It just gives them a sense of understanding that is difficult through speech. That said, I also think it is important to give them multiple examples so that they aren’t locked into one idea of what the assignment should end up looking like. So there you are – after several years of teaching – with more student work examples then space in your desk. Reduce your clutter and organize your examples by using an app called Three Ring. Three Ring allows you to easily digitize student work and create a portfolio of sorts that will consolidate all of your assignment examples into one digital location. From their website: Three Ring is a website that allows you to securely upload photos of student work. You can pull up a student’s work for parent-teacher conferences, administrative meetings, formative assessment, or use as exemplars. Check out this video showcasing Three Ring:
QOTD Archive: Unique uses for a projector in the classroom. #ITTqotd Product Review: Snagit Helps Users Get the Picture | EdTech Magazine Once considered little more than a curiosity, screen-capture utilities are changing the way businesses write documentation — and for good reason. Screen shots quickly and effectively convey ideas that can otherwise be difficult to articulate, saving time and eliminating the ambiguity that can derail even the best of instructions. Released to the general public as shareware in 1990, Snagit was perhaps the first legitimate screen-capture utility of its time. End-User Advantages Snagit loads on Windows startup, takes relatively little memory (less than 50 megabytes on test machines) and invokes a simple interface at the press of the Print Screen key. While free-handing, Snagit provides a real-time picture-in-picture zoom window, so it’s easy to see the exact starting and stopping point that’s being selected on a pixel level. Why It Works For IT If your IT department is like mine, its technicians invest considerable time documenting procedures, both for internal use and end-user education.
Office 365 To Replace LearnLink For Email | The Emory Wheel Emory University will be switching to Microsoft Office 365 for University-wide email and calendar services but will be keeping LearnLink for conference use only in fall 2012, according to Manager of Centers for Educational Technology Kim Braxton. According to Braxton, the University has been using LearnLink for almost 15 years and has been searching for LearnLink’s successor for about three years. Braxton described Microsoft 365 as a cloud-based service that provides email, shared calendars, instant messaging and storage including a common address book and presence awareness, or the ability to see who is online. The program also has greater email storage compared to LearnLink: Microsoft 365 offers 25 gigabytes per student as opposed to the 250 megabytes LearnLink offers. “That means one mail system and one calendaring system,” Braxton said. “The majority of graduate students moved to Exchange over the past year, so we are finally on the cusp of having one [online community at] Emory.”

Technology Integration Matrix | Arizona K12 Center What is the Arizona Technology Integration Matrix? The Technology Integration Matrix (TIM) illustrates how teachers can use technology to enhance learning for K-12 students. The TIM incorporates five interdependent characteristics of meaningful learning environments: active, collaborative, constructive, authentic, and goal directed (Jonassen, Howland, Moore, & Marra, 2003). The TIM associates five levels of technology integration (i.e., entry, adoption, adaptation, infusion, and transformation) with each of the five characteristics of meaningful learning environments. Together, the five levels of technology integration and the five characteristics of meaningful learning environments create a matrix of 25 cells. What is in each cell? Within each cell of the Matrix one will find two lessons plans with a short video of the lesson.

Cities / Madurai : PIL seeks CBI probe into irregularities in university A public interest litigation petition has been filed in the Madras High Court Bench here seeking a direction to the Madurai Kamaraj University Registrar to lodge a complaint with the Central Bureau of Investigation (CBI) with regard to alleged irregularities and illegal appointments made in the varsity during the tenure of R. Karpaga Kumaravel as its vice-chancellor between 2008 and 2011. I. Ismail, General Secretary of Madurai Kamaraj University Principals' Association, had filed the PIL petition claiming that the irregularities came to light only during the audit report prepared by the Director of Local Fund Audit for the year 2010-11. The report was the subject matter of discussion during the Academic Council and Senate meetings of the varsity held on March 28 last year and March 29 this year. “That is why I have chosen to take up the matter,” Mr. The petitioner said that it would not have been possible for Mr.
Use Podcasts in the Classroom? Consider a new app called Podbay. Many teachers have found great use for podcasts in their classrooms. With podcasts, there is a little something for everyone, which is great for education since pretty much every content area is well-represented. What there hasn’t been, however, is a well designed and effective way to play your podcasts. Apple has the iTunes Store for iOS, which is OK. Enter podbay (App Store link). Consider using it with your students or just for yourself on your way to and from work (as it integrates with most car audio systems perfectly, something Music Store does not).

Tax Watch: Online tests widen schools' digital divide The technological chasm that divides rich and poor may deepen in two years when state standardized tests go online in grades three to eight. This week, Lower Hudson Valley students took the annual English Language Arts test on paper, with pencil. By 2014, the test booklets will be gone, saving the state millions of dollars in printing and postage. But those savings will be achieved on the backs of local districts required to invest tens of thousands of dollars in technology and instruction so students and teachers can make the grade. Districts may need additional technicians to maintain the computers for the tests, now to be used to measure both student and teacher performance. “We are so far from ready, and I don’t see where we’ll get the money to do it,” says Janice Reid, Peekskill’s manager of educational technology. That push a decade later led to development of the Common Core standards, which have been endorsed by the District of Columbia, two territories and 46 states.
School system tweaks its Wi-Fi for better control News April 20, 2012 02:16 PM ET Computerworld - At the Rowan-Salisbury School System in N.C., students and staff use some 7,000 iPads and other iOS devices on a Wi-Fi network stretching across 30 schools. Not surprisingly, networking demands can get tricky. The school system sometimes wants to restrict which printers and displays can be used with Apple's AirPlay and AirPrint technology over Wi-Fi, said Phillip Hardin, executive director of technology at RSSS in Salisbury. Conversely, Hardin sometimes wants to allow a video on an iPad to play on displays in various buildings, some using separate networks called subnets or virtual LANs. Hardin's looking forward to deploying software this summer from Aerohive Networks that allows more detailed management and control of Apple's Bonjour. The tool, called Bonjour Gateway, is now in beta and will be a free software add-on to the school system's Wi-Fi network with its 750 Aerohive Wi-Fi access points (APs), Hardin said.
