LERSUS is an e-learning authoring tool that allows fast and easy production of learning materials for the Moodle LMS.

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.

Didactic  models

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.

Lersus didactic model defines:

 - Structure requirements

 - Function settings

 - Look and feel of the course

 - Export formats


Lersus didactic model helps the author to:

 - 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.

LERSUS Languages

When working with LERSUS, one should distinguish among the three types of language:

  • interface language
  • model language
  • style language (representation language)

Interface language

The interface language is used by:

  • names of main menu items
  • names of contextual menu items
  • names of toolbars
  • titles of the metadata and document structure windows

To change the interface language, do the following:

1.In the main menu, click View > Language

Select the desired language from the list of available languages

Model language

The model language is used by:

  • titles of components in the document
  • titles of paragraphs in the document
  • titles of components on the toolbar
  • titles of paragraphs on the toolbar
  • titles of tabs in the document area

To change the model language, do the following:

1.      In the main menu, click View > Didactic Model Language. The following window opens


2.      Select one of the supported languages

3.      Click ОК

An asterix (*) marks the default language for the current model.

Check Associate with User Interface if you want the model language to change automatically when the interface language is changed.

Style language (representation language)

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.
