IT Support in computer labs
At the school where I work we have a small war going on regarding provision of IT Support staff during lessons in computer labs. Without prejudicing the replies by stating my own position/viewpoint I'd be interested to know how other schools cater for this.
Do you have a technician present in each and every IT lesson?
Do you have one technician based in each lab to provide assistance but also responding to calls nearby?
Do you respond to issues if they arise from a central support section?
Do you have a different approach?
Any and all replies gratefully received!
