Lersus operates on the basis of pre-specified didactic models which define the functionality of the editor and the structure and style of the e-learning materials developed.
There is a didactic model specially developed for the production e-learning courses for Moodle. This didactic model is called easyProf and is also available for free download.
The mechanism of didactic model makes it possible to separate such different tasks as content creation, design, components layout, document development, and the publication. The author is concentrated on the content development. The whole technical side is displayed in the didactic model.
- Structure requirements
- Function settings
- Look and feel of the course
- Export formats
- Ensure didactic and structure integrity of the tutorials
- Determine functional and visual solutions
- Get the format fixed
- Change the structure, format, and design with no effect on the content

All the standard didactic models are available for download from http://www.lersus.de/content/deu/downloads/didactical-models/.
Below you will find a step-by-step guide that will help you create Lersus modules for Moodle.

The style language is applied in ready learning modules after they are exported to the desired format. The style language is used by all the text that is not part of the content (e.g Themes, Tests, Info, References, Glossary, Print Version).
There can be only one style language.
The didactic model included to Lersus installation is easyContent. To start working with the easyProf didactic model, you need to download and install this model first.
