Figure 4.1: The Answer Editor for
Mathematical Expressions (Assessment)

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, including: an Answer Editor for mathematical
expressions, an Answer Editor for graphing in the Cartesian plane (with
x and y
coordinate axes), and an Answer Editor for histograms. 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. 3.6). Also,
context-sensitive help is available on use of Answer Editor through
the Help button at the top of the student
interface.

In much of what follows,
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.
