State-of-the-art in Learning Design Editors - Tools

Tree Based EditorsTree Based Editors

RELOAD RELOAD does not require the user to edit any XML code, simply to dragresources into a tree structure, leaving the application to generate all the code torepresent the tree. RELOAD inspects the resources included by the author and manages all the references to the components of those resources.

aLFanet LDEditor

aLFanet LD Editor uses a tree-based interface and intended for users who already know the LD specification in detail. This editor is embedded in another application which provides it with services.

Komposer Komposer supports user group with limited technological skills by offering predefined pedagogic activities, and a workflow which takes them from authoring to delivery. The complexity of the task facing the author is reduced by restricting UOLs to one role and a single path.

CopperAuthor

The tool is designed to import and merge (incomplete) IMS-LD files. It will offer a Graphical User interface for Coppercore in which users can be added and runscan be previewed using Coppercore.

High Level EditorsHigh Level Editors

MOT MOT is a general purpose high-level graphical editor - aims to providelearning designers with tools which they require to define any structure whichthey may need.

LAMS LAMS is a specialized high level editor that takes as its starting point the sequencing of a set of preset activities, rather than the application of pedagogic templates to content. It does not at present produce or run LD code.

constrained pedagogy, distant from Specification Operational: web-based LD Editor with

client/server architecture, standard protocols used Management/organizational: services of e-

learning environment are used Technological: object-oriented PHP language

with JavaScript, with MySQL Database communications, output is LD XML file, http/ftp protocols used

Standards based: used LD IMS Specification and EML, used SCORM e-learning content
