These older computers either need major upgrades or replacement. New equipment becomes obsolete within a few years and few schools plan or budget a systematic replacement of these machines. Technical Support Most web browsing software is free, but technical support in the classroom is not. Modern computers are easier to use, but they are not television sets. Schools can't just plug them in and expect that they will work perfectly every time a student sits down to do work.
Computers are complex systems with complicated operating systems.
These machines require trained technicians to configure them and troubleshoot the variety of problems that occur in everyday usage. Properly trained technicians and network administrators are expensive and hard to come by. Technicians who can also work with students and teachers are even more rare. Many schools install complex networks, but fail to provide the funds to administer and maintain them. Professional Development Professional development is another huge expense that many school districts fail to adequately fund.
