Technology & the Classroom

In this article by Ian Jukes of The 21st Century Fluency Project, he discusses the role of technology in the classroom. The phrase that stuck out at me was: "Because the most powerful technology in the classroom was, is and will remain...a classroom teacher. But not just any classroom teacher - it has to be a classroom teacher with a love of learning, an appreciation of the aesthetic, the esoteric, the ethical, and the moral - a teacher who understands Bloom and Gardner."

I have had discussions with people and read articles saying that we need to switch to a educational system based around ideas such as the Kahn Academy, in which learning is a very individualized, self-motivated, "high-tech" path, all but getting rid of physical classrooms, if not teachers.

I agree to a certain extent, and I love sites like the Kahn Academy, but the problem is that the only students that will really benefit from this method are those who are self-motivated, genuinely curious learners in the first place, the rest would not suddenly start to care about, say, Algebra just because its now on a computer screen.

So I agree with this article to a certain extent in the same manner; yes, I think that the younger generations do have a certain intuitive link with computers, the internet, and technology, and yes I agree that not only should schools be trying to utilize these tools to their advantage, but that it is inevitable that schools will naturally have to change technologically in this direction just like every other industry on the planet. We should absolutely be educating our students to be technologically savvy to be able to lead the way in the ever globally connected world. On the other hand, I sometimes think that articles like this one can sound a bit exaggerated in that I dont know that technology will suddenly make a higher % of students more interested in learning, because this problem of lack of self-motivation and caring about school has existed long before 20 or so years ago. This % of students, I would have to guess, wont be a drastically different % in a classroom loaded to the brim with technology - though I do believe technology implementation definitely does have a positive effect, if any, I think its more than anything the quality of teacher that matters more at inspiring students.

I do not necessarily think that children in America, on average, seem to be declining in motivation, inspiration, creativity, intelligence, or curiosity relative to the general American populace of any age, nor that they are so ADD or electronically "rewired" that they need to be surrounded by the stuff in order to learn. I do, however, see this trend becoming a growing problem in our society in general, not just in children who are growing up with it. This problem is more complex than I care to go into.

What has seemed fascinating to me is putting our education system into historical relevance, and I havent heard too many people doing that. Correct me if Im wrong, but the last century or two have been a significant historical aberration in regard to to % of educated populace. Before that, it was only a very small % that were fortunate enough to have an education as we know it available to them, and now its not only available, but mandatory, in our country! This is a great thing, but we forget how new this experiment is. I imagine (though just guessing) that those who did receive an education more than a couple centuries ago, would be comparable to our modern classroom's most self-motivated, interested learners.

So now we are faced with the challenge of educating the entire populace - and in an exponentially ever-changing technological world. Keeping up with all the tech is absolutely positive and unavoidable, but it doesnt erase more complex underlying social problems, and it doesnt trump what I believe to be the 2 greatest factors: an inspirational, creative, understanding, intelligent teacher and as small class sizes as possible.

So for SASIC, I think we are doing a great job with infusing technology, and we have some really awesome teachers, and have an atmosphere of creativity and room for the students to become inspired, and stretch their legs out, so to speak. So I think we should keep up the great work, and try to keep in mind that inspiring the students to want to learn throughout their lives, be constantly curious, and express their creativity constructively are the best gifts we can give to them and to our society, species.

Math is Kind of Important

Bad math from Germany's "Bad Bank" leads to $79,000,000,000 mistake, I bet some jobs were lost over that one.

Distribution

Linked here is a site (www.algebrahelp.com) that gives a pretty decent explanation of distribution, which we are learning this week in my Algebra class. For any students needing a second explanation, try reading through the 4 pages and trying the review at the end - bring any questions to me in class or post them below!

Vote For My Students' Photos

My Photography students entered a competition for Raise Your Hand Texas. The assignment was to have each student in their picture answering the question, “What two things inspire you to achieve success?”

They have a chance to win an iPad2, so please vote for their pictures here at Raise Your Hand Texas's facebook, just "like" their pic to vote. My students are in the ESC 20 section of their Photos, toward the bottom of the list.

Michael Harrison's "Revelation"

Composer Michael Harrison has reversed the progression of music history with his 2007 experimental work "Revelation."

Throughout musical history, musicians had been working to find a way to eliminate the dissonant sounds of bad intervals, called "wolf tones" or "wolf intervals." These intervals are the sloppy leftovers that are unavoidable when building instruments using Just Intonation scales or any other scales that utilize perfect ratios, which would include practically every instrument made before the 1700s when Equal Temperment hit the scene.

Every musician back then would have loved to find an instrument that would get rid of these ugly Wolf notes, and the Equal Temperment provided them with this answer and the freedom to easily play in any key... but it came at a price. The beautiful, sparkling sounds of the pure ratios needed to be compromised in the process, so now every guitar, piano, or other "fretted" instrument today plays intervals of notes that are only approximations and are slightly dissonant.

Notes played based on the pure ratios are more rich, resonant, natural, and beautiful sounding in every way, but many of us rarely get to hear them played. Though there still do exist experimental purists out there, such as Michael Harrison. In his "Revelation", he uses a piano tuned to a Just Intonation, and not only uses these usually avoided Wolf Notes, he embraces them and makes them the centerpiece of his song.

These otherwise dissonant intervals create a kind of drone with an audible "beat" at which the pitches fall in and out of alignment. Normally musicians will tune until they cant hear the "beat" anymore, but Harrison uses it to set the tempo for "Revelation", and it provides an almost eerie droning canvas for which to paint over with the sparkling pure tones provided by the Just-ly tuned piano. It works, somehow, and is hauntingly beautiful,
