In contrast to the generally learner-centred ‘educational
technology community’ is a set of powerful for-profit and/or
conservative interests also involved in the promotion and
advancement of the digital re-arrangement of education.
Picciano and Spring (2013) refer to these interests as the
‘education-industrial complex’

❞ The drive towards adaptive learning is being fuelled
less by individual learners or teachers than it is by
commercial interests, large educational institutions
and even larger agencies, including national
governments. How one feels about adaptive learning
is likely to be shaped by one’s beliefs about how
education should be managed.

The question then is, surely, what method of predicting failure (or of
drop-out) is the most reliable, i.e. what method eliminates the most
error? And/or which method can be most easily, quickly, cost-effectively
improved? The data-driven method, or the (traditional) method, of
teachers regularly making predictions (and communicating them to
their students), based on observation of the students’ performance
and/or formative tests?

❞
We should focus on the greatest source of variance that can
make the difference – the teacher. We need to ensure that this
greatest influence is optimised to have powerful and
sensationally positive effects, but they must be exceptional
effects. We need to direct attention at higher quality teaching…

Visible Learning was based on more than 800 meta-analyses of
50,000 research articles, about 150,000 effect sizes, and about 240
million students.
A further 100+ meta-analyses completed since Visible Learning was
first published have subsequently been added.

Much of the data on technology was gathered starting in 1987 (preWindows, pre-internet...). The earliest meta-analysis cited goes back to
1977, 25 are pre-1990 and the next 25 pre-2000 (more than half of the
114 total)
Indeed, in the latest Visible Learning for Teachers, neither ‘computer’, nor
‘technology’ feature in the index at the back of the book….

John Hattie admits that half of the Statistics in Visible Learning are
wrong (…) Hattie reluctantly acknowledges that the CLE has in fact
been calculated incorrectly throughout the book…
“People who don’t know that Probability can’t be negative, shouldn’t
write books on Statistics.”

Hattie declares that the use of computers (sic!) is most effective:
with a diversity of teaching strategies
after teacher training in appropriate use
when there are multiple opportunities for learning
when the student is in "control" of learning
when peer learning is optimised
when feedback is optimised
