  • the standards do not specifv how exactly the components of an e-learning system are to be implemented. So, for example,: a web server or a browser can carry out the communication with the management system. The content may track communications failures or may use a "fire and forget" approach. There have been many interpretations on how the standards should be implemented. Some vendors have used the syntax of the communication, but changed the semantics. By changing the semantics, the software may fail for systems that interpret the communications. In some cases one vendor's interpretation is in conflict with another vendor's.

  • an e-learning gateway server 1 communicates, via the Internet, with multiple e-learning course/content provider systems 2, 3, and 4, and with multiple learning managements systems (LMSs) 10, 11, and 12.
  • LMSs learning managements systems
  • the LMSs 10, 11, and 12 in turn are linked via intranets with student computers 13, 14, and 15 respectively.
  • the student computers 13, 14, and 15 are linked with the gateway server 1 and with the servers 2, 3, and 4 via the Internet. There is therefore full cross- connectivity for all of the systems shown in Fig. 1.
  • the full gateway of the invention comprises the gateway server 1 and also software components installed in the content providers 2,3,and 4 and in the LMSs 10,11, and 12.
  • the gateway 1 performs work flow control for progress of courses involving combinations of the systems 2- 4, and 10-15 shown in Fig. 1.
  • step 21 various inputs are received including:
  • Student data such as LMS identifier, name, authentication data for content sites, and progress data for the activated training, audio/video preferences, and preferred training style.
  • Company profile data such as technical support details, content site rights/limits, workflow and display preferences, limitations, security restrictions (e.g. firewall rules), controls for access to training content and training modes/options, content runtime requirement fulfilment criteria (e.g. plug-in installation sources/limitations).
  • Content Meta data such as identifiers (production and developer), description, name, version, vendor, display preferences, training objectives and structure, training durations, tracking preferences, digital rights/licensing limits, training styles, training depth, complexity, media types, keywords, runtime technology requirements and default fulfilment criteria associated training modes/options.
  • Content source location, portal, and repository details such as authentication requirements and availability of content adapters in the content domain.
  • LMS meta data such as location, domain, name, version, tracking preferences (e.g. compliance levels), availability (visibility to the Internet), usability details (e.g. window creation on launch), and implementation details (e.g. uses Java applet/JavaScript for JSAPI, runtime technologies).
  • the gateway uses this data to retrieve templates for content routing, progress routing, and progress filtering.
  • These templates have the format of a hierarchy of text documents containing JavaScript and data tags.
  • the templates are dynamically selected and filled based on the templates higher in the "execution" hierarchy.
  • the gateway modifies the templates.
  • the templates consist of JavaScript and tags (processing tags and data placeholders). Each template is processed by following the processing tags (flow control) and using the incoming data (student/ content/LMS) to fill the data. In many cases the raw data is used to fill a tag, and some data placeholder tags require some manipulation. The manipulation is based on simple processes.
  • step 24 the gateway directs execution of the work flow to perform its required operations. As indicated by the decision step 25, this is repeated for every required work flow for a course.
  • the modified work flows are then downloaded by the gateway server 1 to the student browser in step 26, which then uses the work flow to direct interfacing of the various systems to complete a course.
  • This may include call-back to the gateway server integration services to receive a sub-workflow or data.
  • Workflows may call to content adapters which in turn may call-back to the server (i.e. the workflow "clients" can come from multiple sources).
  • Example workflows are shown in Figs. 3 and 4.
  • the name "Connect" denotes the gateway server 1.

  • the content is tracked in the student's web browser by cookies, scripting, plug-ins/active control(s) and/or an applet.
  • the progress is communicated to the student computer (client) and on to the management system.
  • the client emulates the management system to the content server. Any time that the gateway 1 is involved in the communications there may be filtering or transformations that takes place in order to emulate the management system or content.
  • the word "Connect” is a name for the gateway 1.

  • the gateway is independent of content vendor and learning management system. It has been built to support any AICC/SCORM compliant LMS, whether it is hosted or installed behind a firewall. If the student can access a standards-based LMS, then the gateway 1 can track the content. Content is tracked by default in the manner best suited to the content and the LMS, but the tracking method can be changed by a content customer request. The gateway can provide tracking for mute content.
  • Basic tracking is a standards-compliant tracking method used to capture progress when none is communicated by the content. Basic tracking includes: Elapsed Time (time spent in the content over a number of sessions), Progress Status (not accessed, incomplete)
  • the gateway can also provide a progress editor that can be used by administrators/students to modify their progress. This is generally only enabled for use on basic tracking units.
  • the gateway 1 organizes mute content into trackable WBT units. Tests can also be created using this service.
  • the gateway 1 can track proprietary content using basic tracking. Progress from uncontrolled content can be filtered to ensure the highest quality progress tracking.
  • Progress filtering is the process of taking the progress communicated by content and filling in the gaps. This could be anything from completing of standard protocol to modification of the progress itself to conform to the expectations for the content or LMS.
  • Any content tracking that is routed through the gateway can be filtered.
  • the gateway 1 provides a very advantageous service for server-driven content. It allows this content to track into an LMS that is not exposed to the Internet. It does this by routing progress through the gateway 1.

  • the progress from a JavaScript API client can be sent directly to the LMS or routed through the gateway 1 (for filtering).
  • the progress from signed JavaScript content can be sent directly to the LMS or routed through the gateway server 1 (for filtering).

Abstract

Selon l'invention, un serveur passerelle d'apprentissage en ligne (1) communique, par le biais d'Internet, avec des systèmes fournisseurs de contenus/cours d'apprentissage en ligne multiples (2, 3 et 4), et avec des systèmes de gestion d'apprentissage multiples (LMS, 10, 11, 12). Les LMS (10, 11, 12) sont à leur tour reliés par des intranets à des ordinateurs étudiants (13, 14, 15). Ces derniers (13, 14, 15) sont reliés au serveur passerelle (1) et aux serveurs de contenus (2, 3, 4) par le biais d'Internet. L'interconnectivité entre les systèmes est donc totale (figure 1). La passerelle selon l'invention comprend le serveur passerelle (1) et des composants logiciels montés dans les fournisseurs de contenus (2, 3, 4) et dans les LMS (10, 11, 12). La passerelle effectue la gestion du flux de travaux pour dispenser les cours impliquant des combinaisons des différents systèmes (2-4 et 10-15). Le serveur (1) génère dynamiquement une définition de flux de travaux et la télécharge vers le navigateur étudiant afin que ce dernier puisse donner les liens pour obtenir les contenus de cours et pour suivre le déroulement des cours. Une option permet à un mandataire sur le serveur (1) d'acheminer un contenu de cours vers le navigateur, au nom du fournisseur de contenus, et de recevoir des données de suivi.
