Brendan McMahan, Daniel Ramage, Google Research Blog, 2017/04/10
One of the problems with learning analytics and analytics in general is that it requires a lot of data. This means you have to watch what a lot of people are doing, which has ethical and privacy implications. More...

The Promise of Administrative Data in Education Research

By Stephen Downes - Stephen's Web. The Promise of Administrative Data in Education Research
David Figlio, Krzysztof Karbownik, Kjell Salvanes, Education Finance, Policy, 2017/04/04
"Although these data are collected for purely administrative purposes," write the authors, "they represent remarkable new opportunities for expanding our knowledge." This short essay (8 page PDF) examines some of the purposes to which administrative data in education could be put, and raises some of the issues associated with using data in this way. More...

Putting data in the hands of students

By Stephen Downes - Stephen's Web. Putting data in the hands of students
Timothy Harfield, Blackboard Blog, 2017/04/18
This is a key point: "Largely absent from mainstream conversations about educational data and student success is a consideration of the role of the student as a learner." It's not surprising to research underline the importance of this. More...

Student/Graduate Survey Data

Résultat de recherche d'images pour By Alex Usher. Back about 15 years ago, the relevant technology for email surveys became sufficiently cheap and ubiquitous that everyone started using them.  I mean, everyone.  So what has happened over the last decade and a half has been a proliferation of surveys and with it – surprise, surprise – a steady decline in survey response rates.  We know that these low-participation surveys (nearly all are below 50%, and most are below 35%) are reliable, in the sense that they give us similar results year after year.  But we have no idea whether they are accurate, because we have no way of dealing with response bias. More...

How to Think about “Better Higher Education Data”

Résultat de recherche d'images pour By Alex Usher. Like many people, I am in favour of better data on the higher education sector.  But while this call unites a lot of people, there is remarkably little thinking that goes into the question of how to achieve it.  This is a problem, because unless we arrive at a better common understanding of both the cost and the utility of different kinds of data, we are going to remain stuck in our current position. More...

Data on Race/Ethnicity

Résultat de recherche d'images pour By Alex Usher. A couple of week ago, CBC decided to make a big deal about how terrible Canadian universities were for not collecting data on race (see Why so many Canadian universities Know so little about their own racial diversity). As you all know, I’m a big proponent of better data in higher education. But the effort involved in getting new data has to be in some way proportional to the benefit derived from that data. And I’m pretty sure this doesn’t meet that test.
In higher education, there are only two points where it is easy to collect data from students: at the point of application, and at the point of enrolment. More...
