COMP. ARTIFACT

The computational artifact: • Identifies the

computing innovation.

AND • Provides an

illustration, representation, or explanation of the computing innovation’s intended purpose, function, or effect.

The written response can be used to aid the understanding of how the computational artifact illustrates, represents, or explains the computing innovation’s intended purpose, function, or effect. Do NOT award a point if any one of the following is true:

? there is no artifact; ? the artifact is not a computational artifact; ? the innovation identified in the artifact does not match the innovation described in

the written response; ? the artifact does not identify the innovation clearly; ? the artifact does not illustrate, represent or explain the innovation’s intended

purpose, function, or effect; ? the artifact illustrates a feature of the innovation instead of the purpose, function,

or effect; or ? the written response describes the innovation’s intended purpose and function

without explaining how the computational artifact illustrates, represents, or explains the intended purpose, function, or effect.

? A computational artifact is something created by a human using a computer and can be, but is not limited to, a program, an image, an audio, a video, a presentation, or a Web page file. The computational artifact could solve a problem, show creative expression, or provide a viewer with new insight or knowledge.

? A computing innovation is an innovation that includes a computer or program code as an integral part of its functionality.
