Input to the ALEKS system is always in the form of proper
expressions and constructions
, never multiple
choice. A critical reason for this is to check students'
knowledge accurately.
The general term for the input tools used in ALEKS is the "Answer
Editor."
This encompasses a variety
of actual modes for user input: an Answer Editor for mathematical
expressions, an Answer Editor for the numberline, and an Answer Editor for
graphing in the Cartesian plane (with x
and y coordinate axes). A student beginning to use ALEKS is trained
in how to use the features of the Answer Editor that are relevant to
the subject (Sec. 3.8).
In much of what follows in
the tutorial, emphasis is on the "Answer Editor for mathematical
expressions," as this is the section which involves the greatest degree
of interplay between mouse, keyboard, and on-screen buttons and icons.
