I've seen oodles of research concluding the opposite at the primary level (grades 1- 5, say). If your mentioned research exists, it must be very well hidden :-/

There were 79 studies used in this meta analysis so it cannot be that well hiddne: https://psycnet.apa.org/record/1987-11739-001

From the first page of that study

> Do calculators threaten basic skills? The answer consistently seemed to be no, provided those basic skills have first been developed with paper and pencil.

So, yeah, there are no studies I have found that support any assertion along the lines of:

>>> There is research that shows that banning calculators impedes the learning of maths.

If you actually find any, we still have to consider that things like this meta-study you posted is already 74-studies ahead in confirming that you are wrong.

Best would be for you to find 75 studies that confirm your hypothesis. Unfortunately, even though I read studies all the time, and even at one point had full access via institutional license to full-text of studies, and spent almost all of my after-hours time between 2009 and 2011 actually reading papers on primary/foundational education, I have not seen even one that supports your assertion.

I have read well over a hundred papers on the subject, and did not find one. I am skeptical that you will find any.
