Beginning in the 1990s, an alliance of fossil fuel and automobile corporations, along with conservative think tanks and politicians, developed a ‘denial machine’ which sought to undermine the scientific consensus on climate change. Between 2003 and 2010, it has been estimated that over $550 million was received from a variety of sources to support this campaign. The Guardian’s current series is an update and reminder of the research into climate change denial that has been carried out in recent years.

In the past, it was easier to trace where the money came from (e.g. ExxonMobil or Koch Industries), but it appears that the cash is now being channelled through foundations like Donors Trust and Donors Capital, who, in turn, pass it on to other foundations and think tanks (see below) that promote the denial of climate change.

The connection between climate change denial and edtech becomes clear when you look at the organisations behind the ‘denial machine’. I have written about some of these organisations before (see this post ) so when I read the reports in the Guardian, there were some familiar names.

Besides their scepticism about climate change, all of the organisations believe that education should be market-driven, free from governmental interference, and characterised by consumer choice. These aims are facilitated by the deployment of educational technology. Here are some examples.

State Policy Network

The State Policy Network (SPN) is an American umbrella organization for a large group of conservative and libertarian think tanks that seek to influence national and global policies. Among other libertarian causes, it opposes climate change regulations and supports the privatisation of education, in particular the expansion of ‘digital education’.

The Cato Institute

The mission of the Cato Institute, a member of the SPN, ‘is to originate, disseminate, and increase understanding of public policies based on the principles of individual liberty, limited government, free markets, and peace. Our vision is to create free, open, and civil societies founded on libertarian principles’. The Institute has said that it had never been in the business of “promoting climate science denial”; it did not dispute human activity’s impact on the climate, but believed it was minimal. Turning to education, it believes that ‘states should institute school choice on a broad scale, moving toward a competitive education market. The only way to transform the system is to break up the long-standing government monopoly and use the dynamics of the market to create innovations, better methods, and new schools’. Innovations and better methods will, of course, be driven by technology.

FreedomWorks

FreedomWorks, another member of the SPN and another conservative and libertarian advocacy group, is widely associated with the Tea Party Movement . Recent posts on its blog have been entitled ‘The Climate Crisis that Wasn’t: Scientists Agree there is “No Cause for Alarm”’, ‘Climate Protesters: If You Want to Save the Planet, You Should Support Capitalism Not Socialism’ and ‘Electric Vehicle Tax Credit: Nothing But Regressive Cronyism’. Its approach to education is equally uncompromising. It seeks to abolish the US Department of Education, describes American schools as ‘failing’, wants market-driven educational provision and absolute parental choice . Technology will play a fundamental role in bringing about the desired changes: ‘just as computers and the Internet have fundamentally reshaped the way we do business, they will also soon reshape education’ .

The Heritage Foundation

The Heritage Foundation, the last of the SPN members that I’ll mention here, is yet another conservative American think tank which rejects the scientific consensus on climate change . Its line on education is neatly summed up in this extract from a blog post by a Heritage senior policy analyst: ‘Virtual or online learning is revolutionizing American education. It has the potential to dramatically expand the educational opportunities of American students, largely overcoming the geographic and demographic restrictions. Virtual learning also has the potential to improve the quality of instruction, while increasing productivity and lowering costs, ultimately reducing the burden on taxpayers‘.

The Institute of Economic Affairs

Just to show that the ‘denial machine’ isn’t an exclusively American phenomenon, I include ‘the UK’s most influential conservative think tank [which] has published at least four books, as well as multiple articles and papers, over two decades suggesting manmade climate change may be uncertain or exaggerated. In recent years the group has focused more on free-market solutions to reducing carbon emissions’ . It is an ‘associate member of the SPN’ . No surprise to discover that a member of the advisory council of the IEA is James Tooley, a close associate of Michael Barber, formerly Chief Education Advisor at Pearson. Tooley’s articles for the IEA include ‘Education without the State’  and ‘Transforming incentives will unleash the power of entrepreneurship in the education sector’ .

The IEA does not disclose its funding, but anyone interested in finding out more should look here ‘Revealed: how the UK’s powerful right-wing think tanks and Conservative MPs work together’ .

Microsoft, Facebook and Google

Let me be clear to start: Microsoft, Facebook and Google are not climate change deniers. However, Facebook and Microsoft are financial backers of the SPN. In a statement, a spokesperson for Microsoft said: “As a large company, Microsoft has great interest in the many policy issues discussed across the country. We have a longstanding record of engaging with a broad assortment of groups on a bipartisan basis, both at the national and local level. In regard to State Policy Network, Microsoft has focused our participation on their technology policy work group because it is valuable forum to hear various perspectives about technology challenges and to share potential solutions” . Google has made substantial contributions to the Competitive Enterprise Institute (a conservative US policy group ‘that was instrumental in convincing the Trump administration to abandon the Paris agreement and has criticised the White House for not dismantling more environmental rules). In the Guardian report, Google ‘defended its contributions, saying that its “collaboration” with organisations such as CEI “does not mean we endorse the organisations’ entire agenda”. “When it comes to regulation of technology, Google has to find friends wherever they can and I think it is wise that the company does not apply litmus tests to who they support,” the source said’ .

You have to wonder what these companies (all of whom support environmental causes in various ways) might consider more important than the future of the planet. Could it be that the libertarian think tanks are important allies in resisting any form of internet governance, in objecting to any constraints on the capture of data?

I was intrigued to learn earlier this year that Oxford University Press had launched a new online test of English language proficiency, called the Oxford Test of English (OTE). At the conference where I first heard about it, I was struck by the fact that the presentation of the OUP sponsored plenary speaker was entitled ‘The Power of Assessment’ and dealt with formative assessment / assessment for learning. Oxford clearly want to position themselves as serious competitors to Pearson and Cambridge English in the testing business.

The brochure for the exam kicks off with a gem of a marketing slogan, ‘Smart. Smarter. SmarTest’ (geddit?), and the next few pages give us all the key information.

Faster and more flexible‘Traditional language proficiency tests’ is presumably intended to refer to the main competition (Pearson and Cambridge English). Cambridge First takes, in total, 3½ hours; the Pearson Test of English Academic takes 3 hours. The OTE takes, in total, 2 hours and 5 minutes. It can be taken, in theory, on any day of the year, although this depends on the individual Approved Test Centres, and, again, in theory, it can be booked as little as 14 days in advance. Results should take only two weeks to arrive. Further flexibility is offered in the way that candidates can pick ’n’ choose which of the four skills they want to have tests, just one or all four, although, as an incentive to go the whole hog, they will only get a ‘Certificate of Proficiency’ if they do all four.

A further incentive to do all four skills at the same time can be found in the price structure. One centre in Spain is currently offering the test for one single skill at Ꞓ41.50, but do the whole lot, and it will only set you back Ꞓ89. For a high-stakes test, this is cheap. In the UK right now, both Cambridge First and Pearson Academic cost in the region of £150, and IELTS a bit more than that. So, faster, more flexible and cheaper … Oxford means business.

Individual experience

The ‘individual experience’ on the next page of the brochure is pure marketing guff. This is, after all, a high-stakes, standardised test. It may be true that ‘the Speaking and Writing modules provide randomly generated tasks, making the overall test different each time’, but there can only be a certain number of permutations. What’s more, in ‘traditional tests’, like Cambridge First, where there is a live examiner or two, an individualised experience is unavoidable.

More interesting to me is the reference to adaptive technology. According to the brochure, ‘The Listening and Reading modules are adaptive, which means the test difficulty adjusts in response to your answers, quickly finding the right level for each test taker. This means that the questions are at just the right level of challenge, making the test shorter and less stressful than traditional proficiency tests’.

My curiosity piqued, I decided to look more closely at the Reading module. I found one practice test online which is the same as the demo that is available at the OTE website . Unfortunately, this example is not adaptive: it is at B1 level. The actual test records scores between 51 and 140, corresponding to levels A2, B1 and B2.

Test scores

The tasks in the Reading module are familiar from coursebooks and other exams: multiple choice, multiple matching and gapped texts.

Reading tasks

According to the exam specifications, these tasks are designed to measure the following skills:

  • Reading to identify main message, purpose, detail
  • Expeditious reading to identify specific information, opinion and attitude
  • Reading to identify text structure, organizational features of a text
  • Reading to identify attitude / opinion, purpose, reference, the meanings of words in context, global meaning

The ability to perform these skills depends, ultimately, on the candidate’s knowledge of vocabulary and grammar, as can be seen in the examples below.

Task 1Task 2

How exactly, I wonder, does the test difficulty adjust in response to the candidate’s answers? The algorithm that is used depends on measures of the difficulty of the test items. If these items are to be made harder or easier, the only significant way that I can see of doing this is by making the key vocabulary lower- or higher-frequency. This, in turn, is only possible if vocabulary and grammar has been tagged as being at a particular level. The most well-known tools for doing this have been developed by Pearson (with the GSE Teacher Toolkit ) and Cambridge English Profile . To the best of my knowledge, Oxford does not yet have a tool of this kind (at least, none that is publicly available). However, the data that OUP will accumulate from OTE scripts and recordings will be invaluable in building a database which their lexicographers can use in developing such a tool.

Even when a data-driven (and numerically precise) tool is available for modifying the difficulty of test items, I still find it hard to understand how the adaptivity will impact on the length or the stress of the reading test. The Reading module is only 35 minutes long and contains only 22 items. Anything that is significantly shorter must surely impact on the reliability of the test.

My conclusion from this is that the adaptive element of the Reading and Listening modules in the OTE is less important to the test itself than it is to building a sophisticated database (not dissimilar to the GSE Teacher Toolkit or Cambridge English Profile). The value of this will be found, in due course, in calibrating all OUP materials. The OTE has already been aligned to the Oxford Online Placement Test (OOPT) and, presumably, coursebooks will soon follow. This, in turn, will facilitate a vertically integrated business model, like Pearson and CUP, where everything from placement test, to coursework, to formative assessment, to final proficiency testing can be on offer.
