# Integrated Semantic Math I/O in ActiveMath: an Evaluation

## Abstract:

The ActiveMath system is a web-based learning environment that
integrates static mathematical content and interactive exercises with
evaluated mathematical input from learners. The mathematical formulæ
in ActiveMath are encoded in OpenMath and presented with regional
notations. Users can input formulæ using the same notations via a
formula editor or using plain-text input. Input to the editor is assisted
by allowing users to copy formulæ from other parts of ActiveMath.
In this paper we describe how all these components are integrated and work
within the system. We will then discuss recent evaluations of the
formulæ input methods run within the LeActiveMath project in Malaga
and Edinburgh. The results indicate that, even though the assisted input
methods provided by the Formula Editor and copy-and-paste are appreciated
by users the most popular input method remains the plain text input fields
for its simplicity and visual space integration. Proposals are made for
how direct input of text can be facilitated and assisted in future
formulæ input systems.
