ITLS Glossary of TermsWisconsin Model Academic Standards:
Information and Technology Literacy is the ability of an individual, working independently or with others, to use tools, resources, processes, and systems responsibly to access and evaluate information in any medium, and to use that information to solve problems, communicate clearly, make informed decisions, and construct new knowledge, products, or systems.There are four categories or content standards in information and technology literacy. These standards specify what a student should know and be able to do. The first two content standards focus on technology use and information processing skills. The latter two build upon the initial categories by adding competencies that deal with attitudes, appreciation, independent learning, teamwork skills, and personal and social responsibility.four content standards area. A complete overview of these standards is contained in the Overview document. A Bibliography of Resources used by the Task Force in creating these model academic standards is also available.

ALA is the voice of America's libraries and the people who depend on them. It is the oldest and largest library association in the world with members in academic, public, school, government, and special libraries. Analog. An analog signal transmits information by modulating a continuous signal, such as a radio wave (see Digital). Analog Signals. Signals that vary continuously by amplitude or frequency. Historically, older transmission systems, like the telephone service, have been analog, while most newer systems are digital in nature (see Digital). Analyze. to determine the components of or separate into component parts; to divide into parts and determine the relation of each part to the other parts, or the whole. Application.

Teleconference. Communication via audio, video, or computer between two or more groups in separate locations. Thesis Statement. A position or proposition which is advanced and is to be supported by information and evidence. Throughput. The rate at which data may be transferred from one computer to another via some sort of electronic medium. Usually measured in bits per second, kilobytes per second, or megabytes per second. Topology. The physical layout of a network. It refers to the way in which transmission technologies are interconnected to form a complete system. Track. The location or path of a recorded signal on a tape or disk. Trademark. A name, symbol, word, figure, letter, or mark adopted and used by a manufacturer, business firm or agency in order to designate the products the firm manufactures or sells and to distinguish them from other products. Any trademark is entitled to be registered under the provisions of a government statute so that it can only be used by the firm who registered it. Transponder.

A visual method of linking information which follows a tree-like pattern with major concepts as trunk, limbs, branches, leaves as extensions or sub-units of main concepts. Tutorial. In contrast to drill-and-practice software, tutorial software attempts to present new concepts and information to students and then help them to understand the concepts and develop skill in using them. The program provides periodic checks on students progress and will then "branch" them to the appropriate next step in the learning process. Sometimes, this means a student will advance to a higher level, or be sent back in the program to review concepts or skills that should have been previously learned. Uplink.
