Rob Abel's contribution to the OSS and OER in Education Series. In this post, he relays a few thoughts on the relationship between open source software that supports teaching and learning and open standards for data and application interoperability in the same space.

Author - Rob Abel, "Open Source and Open Standards". Originally submitted September 19th, 2007 to the OSS and OER in Education Series, Terra Incognita blog (Penn State World Campus), edited by Ken Udas.

About 18 months ago, in February of 2006 I was appointed the CEO of the IMS Global Learning Consortium . IMS is a non-profit member consortium focused on developing open standards for interoperability in the domain of learning and education. My sense was that open source software was an important trend in this domain, especially in the higher education segment. I had some fairly recent exposure to higher ed open source in the U.S. having just completed a research study on current usage and prospective usage. In discussions with the IMS Board of Directors, which included at the time several providers of non-open source solutions (and still does, by the way) there was confirmation on the importance of including open source initiatives in the open standards discussion. Since then IMS has included open source and open technology program tracks in our annual conference and added a couple of open source leaders, Moodle (course management platform) and INFORMS (student and administrative system platform), in addition to some existing participation from the Sakai community , to our active participants.

I’ve also been involved in several invited presentations and panel discussions with some other very smart folks on the topic of open source and open technologies in both the higher ed and K-12 school segments. Through an accumulated experience of two years looking at open source and open standards and how they can, will, or might impact the learning technology segment, I have, at least initially, concluded a few things about open source, open standards and the relationship between them. Since we have a long way to go, I’m offering these as postulates that need to be proven. Here goes:

Postulate number one: open source reference implementations are extremely critical in achieving adoption of open standards for software interoperability.

I think the greatest proof point of this is probably Apache – the availability of an authoritative reference model while organizations are attempting to adopt new interoperability standards is invaluable in accelerating industry participation. In learning standards, our conundrum is conformance.

One of my favorite sayings of the month is, “learning technology interoperability standards – great for researchers or consultants, bad for interoperability.” The point being that pretty much all the specifications developed over the last ten years of progress are well, not very specific. Ethernet they are not. This, above all, in my opinion and in the opinion of many IMS members is the single largest reason that much very good work has been thwarted in terms of its potential for adoption.

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

A ball is thrown straight up.it passes a 2.0m high window 7.50 m off the ground on it path up and takes 1.30 s to go past the window.what was the ball initial velocity

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
