The key points (to me) are:
Solo prediction then group (to get public commitment)
Task: predict, run test, explain actual result.
For groups: agree the prediction (then test) agree the explanation.
Multiple cases i.e. varying variables within a fixed paradigm of test, each
case dictated via a booklet by experimenters.
Group size 4.
Writing down (OE) conclusions at end of group work is important; and selecting between ones from researcher is bad. 1993, 2003
Prior solo task to get public commitment: 1990??
Diffs between social agreement and private interviews
The way most benefits there only after delayed post-test i.e. group itself
doesn't do it alone, but is catalyst for future solo development.
N.B. the task instruction is usually for the group to agree (as if it were an action group).
N.B. EVS can directly implement this solo commitment phase, preceding public discussion.
2000, 2003 take solo:group combination forward; and relate it to concept vs. procedural learning.
Writing down group decisions/consensus is also very important for learning (returning to solo mode??).
And 2003 emphasises how small differences in procedure make big differences: so it is not solo vs. group in general, but the details of what is done in groups.
Progress does not depend on agreement. 2000a, 1990
The "solutions" with most agreement in a group were the most conceptually
advanced.
But the further advance at delayed post-test shows it is not a pre-condition
for advance; and false agreement i.e. regression could then lead to
further advance. So a lot of advance has NO dependence on agreement.
(It may be that measures of agreements in groups are measures of fuller
engagement with the persuasion/explanation task, and it is this that is
productive of learning.)

[Established method of individual then solo i.e. prior public commitment,
to get productive discussion.
Delayed post-test, 5 weeks, solo, in study 1; in study 2 2-week delay.
No rel. of change to pre-test i.e. advanced also advanced further. Compared 3 groups:
similar views, differing in both level and view within a level, differing only
in view but same level. N=121 Mean increases at best 10% of the scale.
Already it shows that advanced kids regress in group, then overtake their
pretest by delayed post test. And that progress correlates with nmb. of
agreements within the group.

12-15 years old; computer presented, but group work. Falling objects (and wind
resistance). Predict and explain. Solo paper test; 5 week gap; pairs at
computer with their paper work, simulation/animation, and computer presented
tasks; 1 week gap; paper post-test.
No gender diff in overall effects, but in method of discussion. Males: they
notice difference in prediction, then discuss preconceptions, then advance
their conceptions. Female: no rel. between predict and expl; but discussing
expls caused advance. MF pairs discussed less, and resolved less.

[9-12 year olds. Domain is shadow size caused by diff. brightness, distance
etc.
Issue is proc. vs. conceptual learning.
Proc requires contingent tutoring from an expert; but conceptual growth
requires peers, no authorities, differing views.
Her wheeze here is to require consensus as a bridge, and get the best of both.
So they do group without T first; get consensus; then T does scaffolding on a
proc task. Task was deciding how to do a good expt. test.
It's also about a) metacog; b) hyp testing; c) explanation vs. prediction vs.
acting.
Metacog: realising that the exercise was a test, not just a task. Her arg. is
that consensus was important in getting the Ls (the group) to make that
connection and keep it in mind while acting, and while getting contingent
shaping from T. For her cog. engagement is doing the task; metacog engagement
is relating the task to the concept, to it being a hyp-test. And it's about
the kids "owning" the test and the hyps; which in typical CT interactions they
don't. I.e. the issue Piaget was getting at is that adults poison fruitful
debate because the Ls don't own the expls and hyps. Or to put it another way:
real uncertainty about the outcome and the concept.]

In fact, she says this suggests there is some value for group work for proc
learning (at least this kind of proc: hyp testing). ]
