Abstract :
The system specified in this document presents applications of the LEVERAGE system running on workstations and not involving the system functionalities. Those functionalities are split into 2 groups:

  • functionalities called by the basic LEVERAGE application such as material preparation tools, help, exercises and glossary-dictionary which are add-ons of the basic LEVERAGE application designed to increase the field of action offered to users
  • statistics used by advisors of the system for evaluation.

The LEVERAGE language course material comprises the course text, exercises, multimedia elements and reference works. Within the Leverage system reference material is implemented via the dictionary module. The dictionary is specified as a WEB-application. This means it runs in a separate browser window and presents an application interface via HTML. This HTML is generated with the "WebComplex" software. This software is implemented as a CGI process on the NT-Server.

The LEVERAGE courseware material can be edited during the user trials. For this purpose a set of material preparation tools is provided. As there are plenty of commercially available tools, it has been decided to use as many as possible of these off-the-shelf tools and to develop only the missing parts if needed.

To assist the students and teachers in using the Leverage system during the trials, a help system has been added. This system contains general help about the Leverage architecture and help concerning each application.

An evaluation system is provided with the LEVERAGE system. This system collects sets of data that may be clearly defined to give evaluators a good working basis.

The exercise module provides an interactive way to do exercises belonging to a specific task in the language course. Teachers can create the exercises belonging to a specific task. The students can independently practice elements in the language course via the exercises.
