On the practical side some e-learning is about organizing the topics to be taught and creating multimedia CDROMS or web sites. An important advantage is generally seen in the fact that hyperlinking is possible and having interactive parts illustrating difficult things or for doing exercices.
Often a design approach is implemented which involves creating or re-using learning Objects. These are self contained units properly tagged with keywords, or other metadata, and preferably stored in an XML file format. These are put in a database and creating a course requires putting together a sequence of learning objects.
One important point is to help teachers organize their pedagogical perspective. Some institutes for Higher education are devoted to this mission (training, counselling, funding, developpment, etc.). One example (IPM) may be found in Belgium: http://www.ipm.ucl.ac.be (website in French). The general philosophy (in English) for promoting E-learning and others technological tools may be found in http://www.ipm.ucl.ac.be/Marcel/TDM_english Claroline (see below) was developed by IPM (namely, Institute for Pedagogy AND Multimedias).
More recent approaches focus on dialogue, interaction and collaborative activities - courses still contain content but it is of secondary importance or is generated by the students. An open source course management system that makes this approach easier is Moodle (see below). This advocates Social-Constructivism as a pedagogical perspective, whereby learners construct their knowledge through discussion, thereby enhancing their thinking skills.
Organizing the content
Creating media
Binding it together Most often HTML is used to bind together the different e-learning media. Sometimes XML based files are created which are then rendered to HTML/CSS/JavaScript by using an XSLT transformation. However often proprietary techniques are used like Macromedia Director, an authoring tool which contains a Object-BASIC like scripting language.
A standard for representing e-learning content is SCORM.
