Once computer networks are installed and configured (usually in consultation with external engineers and technicians), system administrators employed by the school ensure they remain operational and functional. These professionals listen for network problems by both attending to reports of malfunctions from users and by monitoring system logs, and they both resolve problems that are identified Read More

Edtech for Edleaders: Local Area Networks
84: Edtech for Edleaders: Local Area Networks Local area networks (LAN) entered most educators’ experience in the mid-1990’s when the first servers to be regularly accessed by teachers and students arrived in schools. Early uses of LAN’s in schools included connecting multiple computers to a shared a printer and sharing files using a folder (or Read More
Edtech for Edleaders: A Rationale
Opening the door and peering into the wiring closet where network devices are installed can be an intimidating experience. These rooms tend to be filled with white noise (generated by fans moving air which is cooled by air conditioners that operate day and night during all seasons) and racks of switches with large tangles of Read More
Edtech for Edleaders: Computer Rooms Today
Appropriate Proper Reasonable While computer rooms have largely fallen out of favor, they continue to be maintained in many schools. As more diverse computing devices have entered the educational market and Internet-only notebooks became more popular, computer rooms have become more important for providing capacity for specialized purposes that require sophisticated software that must be Read More
Edtech for Edleaders: What We Want in IT Systems
When describing the IT systems they build and manage, IT professionals use three words to describe their systems (or at least they try to build systems that can be described with these three): Reliable systems are available whenever users need them. Internet services providers, web hosting companies, and similar network vendors will describe their “up Read More
What Larry Cuban Said About Technology is (Discouragingly) Still Accurate
The computer technologies introduced to schools in the last quarter of the 20th century were part of a long parade of electronic information technologies that were introduced first into the popular culture and then into education throughout the 20th century. In 1986, Larry Cuban, a professor of education at Stanford University, reviewed the history of Read More
Edtech for Edleaders: Whom to Hire- CIO
It is only recently that educational organizations have adopted the practice of using “c-level” title for those in management positions. Chief financial officers (CFO) manage the business operations of schools and chief academic officers (CAO) are responsible for all aspects of teaching and learning within schools; individuals in these roles report to the chief executive Read More
Edtech for Edleaders: Capacity of Computing Devices
Teaching and learning requires students access and consume information, analyze and manipulate it, and create and disseminate it. Some educationally relevant information tasks, such as consuming text-based web sites (e.g. Wikipedia) and composing text (e.g. writing research papers) require little computing capacity; the rate of data creation is a small, the necessary processing power is Read More
The Problem with Data
Data is atopic that has been addressed on this blog previously: Being Data Driven is Nothing to Brag About Data versus Evidence If you read those posts, it is going to become clear that I am not a fan of the fascination educators have developed for data. It can be a part of how we Read More
Edtech for Edleaders: Routing & Switching
For networks to function, packets of information must make it to the correct destination (to the correct IP address). This depends on accurate addressing and also on effective routing. As the name suggests, a routing is the network function in which packets are sent via a route to their destination. Routing occurs between the LAN Read More
