General+Classroom+Schematics-Design

When designing a classroom environment conducive to effective technology use, consider the purpose and use of the room. For example, the layout of an elementary classroom with a pod of five computers will differ substantially from a high school that utilizes a laptop cart. Additionally, the size and layout of a legacy room will dictate the number of possible design scenarios. Electricity and connectivity needs will limit the possibilities; a standard personal computer requires at least two 110-volt electrical connections and an Ethernet connection. The following are possible schematics for classroom computer use: Individual schools must decide the optimal classroom designs for their technology. They also must consider proximity, placement, and lighting, including the following decisions:
 * Pods: ** Grouping computers within the regular classroom can be an effective use of technology. Each workstation should be a minimum of 30 inches wide to allow for a full-size keyboard; if the students work regularly in partners or groups, more space will be needed. When possible, spread the computer stations around all four walls of the classroom to allow collaborative work and encourage learning centers.
 * Desktop: ** Placing one personal computer at each desk is essential when privacy and distractibility are issues, such as with online assessments. This is a common computer lab design. In legacy rooms, electricity and connectivity issues often force the desks to be arranged along the walls, which results in students sitting with their backs to the instructor. In rooms designed specifically for computer use, a tiered classroom design allows for more teacher/student interaction. In addition, cables or wires are generally run discreetly (e.g., not across aisles).
 * Laptop Carts: ** Portable computer carts add a multifunctional component to regular classrooms; teachers and students can determine the arrangement that suits the lesson needs. Students can work in groups or individually; computers can be arranged in a standard classroom design or in workstations. This schematic requires a wireless access point suitable for multiple connections.
 * Computer placement: ** A standard keyboard requires approximately 30 inches of space; more may be necessary if the desk also will be used as a workspace. All screens should be placed approximately 30 inches from the users’ eyes. While flat-panel screens require little additional depth, more space must be allowed for CRT monitors. A 15-19-inch CRT monitor requires about 30 additional inches of depth; 21-inch CRTs require 36 inches.
 * Desk Placement: ** Aisles between desks should have a minimum width of approximately 36 inches; for wheelchair access, 42 inches is preferable. Staggering desk rows increases width and accessibility. Desks should be placed parallel to windows, when possible, to reduce screen glare. Suitable chairs should be chosen with ergonomics in mind; those with height adjustability and a broad seat and back are ideal.
 * Printers and Other Peripherals: ** The location of printers, projectors, VCRs, printer paper, and other miscellaneous supplies must be considered. Space for free-standing or built-in units must be planned.
