"The frustrations teenagers experience with school are more a case of statistics and lack of experience than that of work ethic or "attitude" problems. These statistics are not tied to socioeconomic status, weight or time spent in a seat; they're genetic and experiential. We have a bell curve of abstraction and experience, and we're only beginning to think about how to honor that."

"Comics are also great at abstracting away details so that readers uses their imagination to focus on what they want. You draw a character simply so that the readers can insert themselves or someone they know and relate to the character. This abstracted style of art also leaves room for comics to be incredibly expressive. Whether it's a smiley face, the dynamic motion of a superhero, or Charlie Brown missing a football, the medium communicates a lot with very little."

"On 4 and 5 October 2012 the 6th European Conference on Games-Based Learning took place in Cork (Ireland). The Conference on Games-Based Learning (ECGBL) offers an opportunity for scholars and practitioners interested in the issues related to games based learning (GBL) to share their thinking and research findings. It also presents an opportunity for networking with others in this growing field of research. The  abstracts of all presentations  is available as a downloadable pdf."

The first two-dimensional bar codes, or QR codes, as they're known, were installed Friday at Arpoador, a massive boulder that rises at the end of Ipanema beach. The image was built into the sidewalk with the same black and white stones that decorate sidewalks around town with mosaics of waves, fish and abstract images.

"Teaching and learning may rest on processes invisible to the naked eye; but lessons and courses are spatiotemporal things: activities with extension and duration, leaving traces, demanding behaviors. And in order to get a hold of teaching and learning, at some point we need to move from the abstractions to the concrete activities. Teaching a course or a lesson, and taking a course or a lesson: these are concrete physical activities. And project management gives us a good analogy for what the dimension of learning which is not theoretical but is absolutely necessary."

""Where's the beef?" was the famous campaign slogan from the 1984 Presidential campaign. For two years, MOOC watchers have been asking the same question, as hundreds of thousands of students participated in free online courses that delivered knowledge but no certification of any real value. The Georgia Institute of Technology recently changed all that: Its May 14 announcement that the school would offer a fully accredited Online Masters of Science in Computer Science (OMS CS) for less than $7,000 suddenly brought the abstract potential of MOOCs into stark relief."

"In a student-centric LMS, the core abstraction of the LMS is the student. In the diagram, I'm imagining a student with control of connections to other entities within the system. These could be instructors, or other students, or learning materials. To create a course, you invite students to connect with a common set of resources, one or more instructors, and the other students in the course. When the course is complete, the student can drop the connections she doesn't need any more - but keep the rest. As the educational experience proceeds, the student collects, under her control, the connections that remain meaningful and useful and drops the ones that are stale or irrelevant. Furthermore, these resources could be local and within the LMS, or they could be external to the LMS or to the student's current institution."

"That feeling of quality is the hardest thing for many developers to master. Well-designed code feels good to work with, and ugly code will make developers involuntarily cringe. The best developers learn to fuse abstract logic with the sensitivity of an artist. Learning to trust that aesthetic feeling is as much a part of development as any algorithm or coding pattern."

"Although there have been many claims that technology might enhance university teaching, there are wide variations in how technology is actually used by lecturers. This paper presents a survey of 795 university lecturers' perceptions of the use of technology in their teaching, showing how their responses were patterned by institutional and subject differences. There were positive attitudes towards technology across institutions and subjects but also large variations between different technologies. Two groups of technology were identified-"core" technologies, such as Powerpoint, that were used frequently, even when lecturers felt that they were not having a positive impact on learning, and "marginal" technologies, such as blogs, that were used much less frequently and only where they fitted the pedagogic approach or context. Rather than there being "leading" universities that were the highest users of all technologies, institutions tended to be heavier users of some technologies than others. Similarly, subjects could be associated with particular technologies rather than being consistent users of technology in general. The study suggests that university technology policy should reflect different disciplines and contexts rather than "one size fits all" directives."
