The web service for managing repair requests that is web-based are often called “ticketing systems,” because one submits a “help ticket” that summarizes a problem; the ticket is assigned to someone with the skill and network credentials to fix the problem, and notes regarding steps that are taken are added to the ticket. Once the Read More
Fundamentally, computer networks are simple systems. To build a network, one provides a pathway to move data from one node to another (through electrical signals transmitted over wires or radio signals that travel through the air), gives every node a unique address (so the network “knows” where to deliver packets), and then keeps track of Read More
Several years ago, I was asked to gather some “data” regarding “how our school technology is doing.” I was familiar with technology acceptance model, and intended to ground my answers to the inquiry in data collected with a valid and reliable instrument. Turing to the literature, I found there were instruments for measuring Unified Acceptance of Read More
At its most basic level, the World Wide Web is a collection of servers; these computers are always powered on and connected to the network. Files on a web server are contained in a directory that is configured to allow outside users to read the contents, and the file is read when a visitor uses Read More
In reviewing some data I gathered and prepared for presentation in the last year, I found four factors that were positively associated with the decision to adopt and the decisions to continue to use educational technology once it had been adopted: Improvement: Which was summarized as “the degree to which the planning method solved the Read More
One focus of professional development relative to information and computer technology (ICT) in schools has been managing it. When computers first arrived, and machines were stand-alone devices, individual educators were able to manage the computers in their classrooms with independence; software was purchased for single machines and printers and similar peripherals were connected to specific Read More
Correlation does not mean causation… just because your computer malfunctioned soon after you (or someone else) did something to a computer or a system or your network or your software and it malfunctioned soon afterwards it does not mean the change cause the problem.
Hermeneutic researchers fall into the hermeneutic cycle (see figure 1) in which an artifact is interpreted in light of the culture and then the culture is reinterpreted in light of the emerging understanding of the artifact. This cycle between the whole of the culture being reconstructed and the parts of the culture embodied in the Read More
In the previous sections, an oversimplified version of technology decision-making has been presented. Cost (a very important consideration for reasonable decisions) and computing capacity (also important in consideration for ensuring sufficient computing is available) have been identified as the factors relevant to purchase decisions. While cost and capacity may be the dominant factors when deciding Read More
Another common negotiation is between the available capacity and the nature of the information task in the curriculum. In situations in which the complexity of the information task is beyond the capacity of the devices, teachers may reconcile the complexity of the tasks with the capacity of the devices. Consider video editing, which is a Read More
