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. Mathematical formulæ in ActiveMath are
      encoded in OpenMath and presented with regional nota-tions. 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 will 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 pro ject 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. Proposals are made for how direct input of text can be facilitated
      and assisted in future formulæ input systems.
