The Use of PSPP in Learning Statistics

[John Darrington]

Somebody pointed out this research paper to me:

Whilst I'm personally pleased that the authors give a positive conclusion,
I can't help thinking that their methods and their reporting could have
been a lot more rigourous.

The paper doesn't seem to pose a clear hypothesis.  Their survey questions
are not described except very superficially.  What is most concerning, is
that they don't seem to have used a control group.

... Also they mistyped my name :(  ...

I wonder if anyone is aware of any other studies on the efficacy of PSPP ?
