You may be interested in R software I have been using for 4 years now to
support my second level undergraduate statistics for psychologists course. This
allows instructors to develop R modules that permit interactive investigations
of statistical methods online. Students' computations (including R code, data,
results tables, figures...etc) are archived using a 'blogging' system,
providing URLs they can embed in reproducible documents ('compendiums') written
for their assignments. My course also uses an associated peer reviewing system
enabling a socially constructive statistical learning environment. The same
platform supports reproducible scientific writing and statistical analysis, and
the developers of the platform now have a series of papers (I am a co-author on
a few) you can consult about details at www.freestatistics.org . The latter
hosts the reproducible computing platform and the statistical learning platform
is at www.wessa.net/rfc Further details are available fr!
om the main developer Patrick Wessa who can be contacted via either route.
There are scores of R modules already developed and freely available, and I
believe course materials such as mine could be shared with instructors
interested in developing their own online courses using the RFC platform too.
Patrick has talked at previous R-user conferences about this software, and I
also gave a talk at the Warwick conference in 2011 on my experiences using it
- I think the podcast may still be available. Yes, they are here:

There remains however a demand from my students (and colleagues) that students
are exposed to SPSS as this is perceived as 'the gold standard' for statistical
analysis, in psychology at least, and students want to be able to put
'proficient in SPSS' on their CVs. Note: not 'proficient in statistics'!
Colleagues who have used SPSS for years (almost exclusively for anova and
regression, tasks for which SPSS is, to my mind, a needlessly expensive
solution) are unwilling to use other software and some even seem to find it
difficult to recognize the same information when presented in an unfamiliar
format. One even scribbled 'what's this nonsense?' on a student's work when
sh/e chose to use QQplot and density plots from an R module in their research
project!
I also strongly support Christopher's comment about reproducibility potentially
being a key driver for the uptake of R, but most scientific authors will not
make their research reproducible until journal requirements or institutional
directives force them to do so. These have both been tried and have failed, as
papers still get published without meeting these requirements even when they
have been in place. The one other potential driver for the uptake of R more
widely would be powerful new statistical tools not available elsewhere that
offer scientific writers increased publication success and ease of production.
Here's where a platform like http://rfc.wessa.net/ possibly has a USP. Given an
exemplar analysis one simply has to paste in new data into the data panel on an
R module online and recompute the analysis allowing one to communicate new
results within seconds without any local software or computation at all - you
can even do this from your mobile device, as a lot of m!
y students do.
