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 bar graphs, and a variety of tools replicating business forms and documents. 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.
