Scrap the iPads, Keep the Pianos, Get a Teacher #4

Some blog followers might be interested in a recent post “Scrap the iPads, Keep the Pianos, Get a Teacher #4” [Hake (2013)]. The abstract reads:

**********************************************
ABSTRACT: Superintendant of the Los Angeles Unified School District John Deasy http://bit.ly/1aq9KHo has initiated a controversial one-billion-dollar initiative to equip all students and teachers with iPads. In reaction, L.A. elementary-school teacher Jeff Lantos, wrote an opinion piece in the L.A. Times titled “Scrap the iPads, keep the pianos: Want a device that can inspire, critique and put on a show? Get a teacher” at http://bit.ly/1a9XmZP.

Therein Lantos, recalling his 1986 positive experience with an Apple-funded program at the Open Magnet School in West Hollywood (spearheaded by Alan Kay http://bit.ly/eQCb6t, which placed computers into elementary-school classrooms, first offered strong evidence FOR the value of computers in the classroom.

But then Lantos seemed to switch fields, arguing AGAINST computers in the classroom in comparison with teachers and pianos. Lantos opined that (a) “if one wants a device that can inspire, critique and put on a show, get a teacher,” and (b) if it were to be a choice between iPads and pianos he would scrap iPads and keep the pianos. Lantos ends his essay with: “I have a piano in my classroom. My students start each school day with 15 minutes of singing and dancing. In January, I conducted an experiment. I said to my students: ‘We’re facing drastic budget cuts. We have to get rid of either the 15 laptops or the piano. Which should it be?’ I don’t think I have to tell you the response.”

However, considering Lantos’ earlier-cited strong evidence for the value of computers in the classroom, it’s not clear that everyone would vote the same way as Lantos’ elementary-school pupils. Furthermore, considering the importance of education to the lives of people and to life on Planet Earth – see e.g., “ ‘Where is Everybody’ . . . .” [Hake (2013)] at http://bit.ly/H3roIC (6.8 MB) - the choice for the U.S. should not be to pick one, two, or none from among computers, pianos, and teachers, but to chose ALL three of those benefits and to work towards the reduction of poverty, the root causes of poor academic performance in the U.S. - see e.g., “Hake's Reading List on the Root Causes of Poor Academic Performance” [Ravitch (2013)] at http://bit.ly/12CKARz.

Inadequate Teacher Education: Averse to the Best Interest of Science Communities and to Life on Planet Earth

Some blog followers might be interested in a recent post “Inadequate Teacher Education: Averse to the Best Interest of Science Communities and to Life on Planet Earth” [Hake (2013)]. The abstract reads:

**********************************************
ABSTRACT: Meltzer, Plisch, & Vokos (2013) in a recent APS News essay at http://bit.ly/1arpo3C reported that “The national landscape of physics teacher preparation shows a system that is largely inefficient, mostly incoherent, and completely unprepared to deal with the current and future needs of the nation’s students. . . . . Most physics departments currently avoid playing an active role in physics teacher education. We believe this avoidance is not in the best interests of the physics community.”

Similar comments could probably be made for science-teacher preparation generally. Inadequate teacher education is averse not only to the best interests of science communities. More importantly, it’s averse to life on Planet Earth. For a recent return to that 24-year-old theme see “ ‘Where is Everybody?’ Failure to Detect Intelligence in the Universe is Due to Failure of Universities Throughout the Universe” [Hake (2013)] at http://bit.ly/H3roIC (6.8 MB).

Would a Carbon Tax Alone Save Life on Planet Earth? Probably Not: Overpopulation Must Also Be Addressed

Some blog followers might be interested in a recent post “Would a Carbon Tax Alone Save Life on Planet Earth? Probably Not: Overpopulation Must Also Be Addressed” [Hake (2013)]. The abstract reads:

********************************************
ABSTRACT (CAPS in quotes are mine): As I pointed out in a post “Would a Carbon Tax Save Life on Planet Earth?” [Hake (2013a)] at http://yhoo.it/16ECfUn, Hansen & Romm (2013) at http://bit.ly/12djtSf wrote:

“We must have a simple, honest, across-the-board carbon fee COLLECTED FROM THE FOSSIL FUEL COMPANIES AT THE SMALL NUMBER OF DOMESTIC MINES AND PORTS OF ENTRY. All of that money should be distributed to the public -100 percent of it - with equal amounts going to all legal residents.”

Art Hobson (2013a) in an OpEd “Our planet passes a climate benchmark” at http://bit.ly/19tBwGD made a similar point but did not indicate, as did Hansen & Romm, that the carbon fee should be “collected from the fossil fuel companies at the small number of domestic mines and ports of entry.”

Al Bartlett (2013a) responded at http://bit.ly/10loNjf to Hobson's OpEd thusly:

“Here I want to comment on the FIRST OF TWO OMISSIONS in your otherwise excellent and comprehensive presentation. . . . . The ‘stop emissions’ is right on but unrealistic. As long as there are humans on earth, emissions of CO2 will continue at some level. It seems to me to be more realistic to say that: ‘We must embark on a long-term program of continually reducing the annual number of tons per year of greenhouse gases that are released world-wide into the Earth's atmosphere.’ . . . . [To do this] we have to STOP GLOBAL POPULATION GROWTH AND THEN REDUCE THE SIZE OF THE GLOBAL POPULATION TO SOME "SUSTAINABLE" LEVEL. And in a later post Bartlett (2013b) at http://bit.ly/11Og32G stated: “You did state that the solution is to put a tax on carbon. . . . . . The next question that needs to be addressed is: Given the real world in which we live, WHAT IS THE PROBABILITY THAT ON ANY USEFUL TIME SCALE WE CAN ACHIEVE THE GOAL . . . .. OF STOPPING CARBON EMISSIONS BY MEANS OF . . . . . . .PUTTING A TAX ON CARBON?”

Bartlett (2013c) discussed the SECOND OMISSION in a post “Exporting U.S. Fossil Fuels” at http://bit.ly/14sPuBM, stating: “Art and most of the environmentalists who strongly advocate the reduction of U.S. carbon emissions omit one important point. The U.S. exports a significant fraction of the coal that it mines. Thus U.S. coal is burned in other countries where it makes about the same contribution to global warming as it would have if it had been burned in the U.S.”

Hobson (2013a) may have “missed a point,” but Hansen & Romm (2013) did not!

As indicated above they, unlike Hobson, specified that “the carbon fee should be collected from the fossil fuel companies AT THE SMALL NUMBER OF DOMESTIC MINES and ports of entry.” Thus Hansen & Romm's carbon tax would discourage coal mining in the U.S. regardless of whether or not U.S. coal is shipped out of the U.S.

Hobson, in a response at http://bit.ly/124gGEU appeared to be unaware of Hansen & Romm (2013) and failed to make the above argument. But Hobson agreed with Bartlett that THE OVERPOPULATION PROBLEM NEEDS TO BE ADDRESSED SIMULTANEOUSLY WITH THE IMPOSITION OF A CARBON TAX. I also agree with Bartlett - see e.g. “L.A. Times Population Report: Beyond 7 Billion - Fighting the Last War?” [Hake (2012)] online on the OPEN! AERA-L archives at http://bit.ly/TeOpJj.

Can be attributed to the actions of humans,
Then this is positive proof that the human population,
Living as we do,

Assessment of Climate Change: A Challenge for the University

Some blog followers might be interested in a recent post “Assessment of Climate Change: A Challenge for the University” [Hake (2013)]. The abstract reads:

**************************************
ABSTRACT: ASSESS subscribers (a) Larry King at http://bit.ly/195skV6 & http://bit.ly/11aNwHy, and (b) Mike Fulford at http://bit.ly/17IgiTZ questioned the relevancy to assessment in higher education of my posts “Senator Sheldon Whitehouse - Time to Wake Up: GOP Opposition to Climate Science” at http://yhoo.it/100EVIY and “Why Democrats in Congress Fail To Support Climate Change Legislation #3” at http://yhoo.it/100EVIY.

Irrelevant to assessment in higher education? King and Fulford may have missed my post “Would a Carbon Tax Save Life on Planet Earth?” at http://yhoo.it/16ECfUn. If there’s no life on Planet Earth then there's neither Higher Education nor Assessment on Planet Earth.

Karl Pister, Emeritus Chancellor of UC - Santa Cruz, wrote at http://bit.ly/11ymbuk: “. . . we need to encourage innovative ways of looking at problems, moving away from the increasing specialization of academia to develop new interdisciplinary fields that can address complex real-world problems from new perspectives.”

Surely the assessment of the alleged threat to life on Planet Earth by anthropogenic global warming is A Challenge To The University rather than the Irrelevancy seen by King and Fulford.

Would a Carbon Tax Save Life on Planet Earth?

Some blog followers might be interested in a recent post “Would a Carbon Tax Save Life on Planet Earth?” [Hake (2013)]. The abstract reads:

**************************************
ABSTRACT: James Hansen, former head of the NASA Goddard Institute for Space Studies, in "The Courage to Fight Climate Change" at http://bit.ly/12djtSf wrote: “We must have a simple, honest, across-the-board carbon fee collected from the fossil fuel companies at the small number of domestic mines and ports of entry.

A Google http://www.google.com/ search for “Carbon Tax” turned up 4,210,000 hits at http://bit.ly/153PQQV on 03 June 10:30-0700, including the Wikipedi entries on “Carbon Tax” at http://bit.ly/118dUBp and on “Emissions Control” at http://bit.ly/15tshjV. In my opinion: (a) The more important hits are listed in the over twenty references in the REFERENCE list in the complete post at http://yhoo.it/16ECfUn, and (b) the most important hits are these six:

Should Global Competitiveness Be the Main Driver of Education Reform?

Some blog followers might be interested in a recent discussion-list post “Should Global Competitiveness Be the Main Driver of Education Reform?” The abstract reads:

**************************************************
ABSTRACT: EDDRA2’s Michael Paul Goldenberg pointed to a guest post by Gerald Coles “Educating to Compete in the ‘Global Economy’: Creating Idiot Savantism” at http://bit.ly/NdBMLd. Coles, in turn, pointed to Diane Ravitch's “Flunking Arne Duncan” at http://bit.ly/Ks75SY. Ravitch wrote: “. . . . the nation forgot that education has a greater purpose than preparing our children to compete in the global economy.”

I agree with Coles and Ravitch that “global competitiveness” should not be the main driver of education reform. In a discussion list post “Is the 'Skills Slowdown' the Biggest Issue Facing the Nation?” at http://bit.ly/9kIHAW, I countered David Brooks’ claim http://nyti.ms/LfJp1K that it was, arguing that the “Threat to Life on Planet Earth” was the biggest issue facing the nation.

Likewise, I think the “Threat to Life on Planet Earth,” and NOT “global competitiveness,” should be the main driver of education reform, contrary to the themes of NRC reports: (a) Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Future of 2007 at http://bit.ly/a3g4P3; (b) Is America Falling Off the Flat Earth?" of 2007 at http://bit.ly/qwdyDu; and (c) Rising Above the Gathering Storm, Revisited: Rapidly Approaching Category 5 of 2010 at http://bit.ly/dtQhbS.

“The global population is precariously large, and will become much more so before peaking some time after 2050. Humanity overall is improving per capita production, health, and longevity. But it is doing so by eating up the planet’s capital, including natural resources and biological diversity millions of years old. Homo sapiens is approaching the limit of its food and water supply. Unlike any species before, it is also changing the world’s atmosphere and climate, lowering and polluting water tables, shrinking forests, and spreading deserts. Most of the stress originates directly or indirectly from a handful of industrialized countries. Their proven formulas for prosperity are being eagerly adopted by the rest of the world. The emulation cannot be sustained, not with the same levels of consumption and waste. Even if the industrialization of the developing countries is only partially successful, the environmental aftershock will dwarf the population explosion that preceded it.”
- E.O. Wilson (1998)

“The paleoclimate record makes it clear that a target to keep human made global warming less than 2°C, as proposed in some international discussions, is not sufficient - it is a prescription for disaster. . . .[[my italics]]. . . Assessment of the dangerous level of CO2, and the dangerous level of warming, is made difficult by the inertia of the climate system. The inertia, especially of the ocean and ice sheets, allows us to introduce powerful climate forcings such as atmospheric CO2 with only moderate initial response. But that inertia is not our friend - it means that we are building in changes for future generations that will be difficult, if not impossible, to avoid.”
- James Hansen & Makiko Sato (2011)
