Dumbing Down Watch

There is a "cheating" scandal at Harvard. Apparently, students were given an open-book, open-anything take-home exam for 'Introduction to Congress' and were not expected to consult each other in any way.
 
Harvard College’s disciplinary board is investigating nearly half of the 279 students who enrolled in Government 1310: “Introduction to Congress” last spring for allegedly plagiarizing answers or inappropriately collaborating on the class’ final take-home exam.
Dean of Undergraduate Education Jay M. Harris said the magnitude of the case was “unprecedented in anyone’s living memory.”
Harris declined to name the course, but several students familiar with the investigation confirmed that Professor Matthew B. Platt's spring government lecture course was the class in question.
The professor of the course brought the case to the Administrative Board in May after noticing similarities in 10 to 20 exams, Harris said. During the summer, the Ad Board conducted a review of all final exams submitted for the course and found about 125 of them to be suspicious.

Presumably this is not the only take-home exam in Harvard and presumably not the first for this course. So why now has half the class felt compelled to plagiarise or to collaborate inappropriately?

Has the course become more difficult than it used to be? Or are the students less capable? Or have admission standards become less rigorous?

Maybe QS and Times Higher were on to something after all when they dethroned Harvard from the number one spot in their world rankings.

New Canadian Research Rankings

Higher Education Strategy Associates recently published their Canadian Research Rankings, which are based on the award of grants and H-indexes. I am not sure about counting grants since it is likely that the skills needed to lobby for grants and those needed to actually do research are not always the same.

The rankings do not include medical research.

The top five for science and engineering are:

1.  University of British Columbia
2.  Montreal
3.  Toronto -- St. George
4.  Ottawa
5.  McGill

The top five for  social sciences and humanities are:

1.  University of British Columbia
2.  Mcgill
3.  Toronto -- St George
4.  Alberta
5.  Guelph


These rankings, like the Times Higher Education (THE) World University Rankings are based on field normalisation. In other words they do not simple count the number of grants and H-index scores but compare them with the average for the field. The rationale for this is that there are enormous differences between disciplines so that it would, for example, be unfair to compare a physicist who has won a grant of 10,000 dollars, which is below average for physics, with an education researcher who has won a similar award, which is above average for education. Equally, does it make sense to rank a physicist with an average H-index for physics well above a linguist with an average one for linguistics?

Here are the average grants for various fields:

biological engineering 84,327
physics  42,913
linguistics 13,147
history 6,417
education 5,733

Here are the average H-indexes for discipline clusters:

science  10.6
social sciences 5.2
humanities 2.3


HESA (and THE ) do have a point. But there are problems. One is that as we drill down to smaller units of analysis there is a greater risk of outliers. So a single large grant or a single much cited author in a field with few grants or citations could have a disproportionate impact.

The other is that field normalisation implies that all disciplines are equal. But is that in fact the case?

A Bit More about Les Ebdon

We have noted that Les Ebdon of the UK government's Office of Fair Access has been lecturing leading universities about the need to admit more students from state schools. If not, they might lose their world class status and could also be fined and forced to charge much lower fees.


English universities will be expected to enrol thousands more undergraduates from working-class families and poor-performing state schools in return for the right to charge up to £9,000 in tuition fees, it emerged.

Prof Ebdon, newly-appointed director of the Office for Fair Access, suggested that one poor student should eventually be admitted for each candidate enlisted from the wealthiest 20 per cent of households.


Currently, the ratio stands at around one-to-seven, he said.
Speaking as he took up his role this week, Prof Ebdon said the country’s best universities were “not going to stay world class in a very competitive world unless they have access to the full pool of talent”


So if Oxford admits 42% of UK applicants from independent schools and they all come from wealthy households and if some of the state school applicants also come from wealthy households so that altogether about half are from privileged backgrounds, then it would presumably have to stop admitting anyone from the middle 60%.

If Ebdon gets his way then it is quite easy to see what will happen. Independent schools will simply arrange for their pupils to do a year at a carefully selected state school after A levels or the schools will open campuses in Ireland (or post-referendum Scotland) so that they can go into the international category.

Ebdon was the Vice Chancellor of the University of Bedfordshire, formerly the University of Luton, which some think is among the worse universities in England, This may be a little unfair: it is almost certainly a better university than Luton Town is a football team.
I wonder whether the next move will be for Ebdon to appointed sports fairness tsar so that he can start telling Manchester United and Liverpool to recruit more players from posh post codes or with more than than one GCSE. Otherwise they will, unlike Luton Town, lose their world class status.
