I think that schools do not see the cost involved when not using sims in the classroom. Primary schools are very conservative when dealing with IT and data with certain staff making decisions that they are really not in a position to make.Schools can save hundreds of pounds in paper, many hours of valuable SLT time and engage parents so much easier by adapting electronically - the teachers themselves spend hours collecting data that is already on the system. By keeping staff at arms length from the data, office staff are implying that teachers are not professional and are incapable of maintaining a simple database. But how many of the teachers have bank accounts, have mortgages and shop on line. Keep trying to crack this intrangience, it is well recorded that when teachers have a shared ownership of data, the pupils' level of achievement increases, parental involvement increases and the school itself raises standards.
