In my opinion, JMC‘s report Digital technologies and mathematics education deserves a careful analysis but not perhaps for reasons envisaged by its authors. In particular, I feel that the report exhibits a patronising attitude to school teachers.
From the begining of JMC’s work on the Report, one of its principal aims was defined as
Identify the reasons why ICT is not being exploited by the majority of teachers of mathematics
And the reason was found: teachers. This is what the Report says:
The recent report from the National Centre for Excellence in Teaching Mathematics (NCETM)  concluded that mathematics teachers‘ concerns about the use of digital technologies related to:a lack of confidence with digital technologies;
- fears about resolving problems with the technology;
- fears about knowing less than their learners;
- access to digital technologies;
- inappropriate training;
- lack of time for preparation;
- a lack of awareness of how technology might support learning;
- not having technology use clearly embedded into schemes of work.
