I am reminded of a situation that arose when I was working as part of a team on a project. Someone in the team had been assigned to find mean averages from a frequency table and use a spreadsheet to produce charts from this.

I noticed that the data presented on the charts were given to an inappropriate degree of accuracy so I checked the spreadsheet seeking to make slight modification to address this. I found that all of the data in the spreadsheet was disconnected. None of the cells were linked. No formula functions had been used. However the averages were 'correct' - although presented to more decimal places than could be justified by the initial data.

When I (gently) discussed this with the team member responsible for the charts it emerged that they had calculated the averages from the frequency tables with pencil and paper and  calculator.  They had then manually entered the data into the spreadsheet. This had taken them many hours to do  - a process that could have been done much more quickly if they had previously had the opportunity to learn about the mathematical power of the spreadsheet . No doubt they had achieved the required grade C in GCSE (UK school exam taken at 16) and presumably answered the question on averages and frequency tables correctly.

Were they being let down by the curriculum and assessment regime in relation to mathematics and ICT - I would say so.

I am sure that colleagues have examples of their own that illustrate the multiple ways that
the ability to do  and communicate mathematics cannot be separated from the tools used and the medium of communication.

Or if someone needs pencil and paper to solve a problem they have learnt using pencil and paper not mathematics? Different media allow different forms of mathematical activity and thinking. Conventions and power (including assessments) determine which of the possible forms are valued.
