Educational modelling language eml

Educational Modelling Language (EML)

  • Developed by OUNL in the late nineties

    • Made generally available December 2000

  • Language for describing Units of Learning

    • All the content and processes in function of learning something

    • A model of the activities, content, tools and workflow for learners and staff to accomplish one or more learning objectives

    • Examples: module, course, curriculum, practical, lesson, …


Educational modelling language

Educational Modelling Language

  • Brought into the standardisation process via IMS in 2001 (www.imsglobal.org)

  • IMS goals:

    • “Defining the technical specifications for interoperability of applications and services in distributed learning”

    • “Supporting the incorporation of the IMS specifications into products and services worldwide”

  • IMS SIG on Instructional Design which led to …


Ims learning design v1 0

IMS Learning Design v1.0

  • Approved February the 10th 2003

  • EML will now no longer maintained or updated

  • EML and IMS Learning Design are very similar, though there are some differences …


Eml and learning design

EML and Learning Design


But why eml ims ld

But why EML/IMS LD?

  • Pedagogical meta model

    • Offers a level of abstraction enabling different educational models to be described

    • Software which knows about the meta-model can interpret specific models—model an approach to learning (eg problem based learning) and have it executed (‘played’)

  • Moves the focus from Learning Objects to Learning Activities ….


My first steps in the e learning world

My first steps in the e-learning world

  • Downloaded Microsoft’s LRN 3.0 Toolkit

    • IMS Content Packaging

    • IMS Meta-data

  • Downloaded all example content packages

  • Things were looking good ….


Things were looking good but

Things were looking good, but …

  • Some engaging content, but each example seemed to be a slight variation of the previous;

  • Learning felt like (only) consuming content

  • Support often looked like page-turning

  • Is this the style of e-learning that the IMS specifications are about?


From learning objects to learning activities

From Learning Objects to Learning Activities

  • What about situations in which learning happens without learning objects?

  • What about when several learners cooperate to solve a problem?

  • Where are the teachers and staff?

  • Learning Design meta-model:

    • Modelling the performance of individual and group learningactivities designed to attain learning objectives and, in the process, making use of learning objects.


Making ims ld learning experiences

Making IMS-LD ‘learning experiences’

  • Learning processes are modelled in the IMS-LD language

  • These models are ‘played’ in an IMS-LD-aware player;

  • Analogous to marking-up learning materials in HTML and having a browser interpret them


Ims ld concepts

IMS-LD concepts

  • People act in different roles

  • working towards certain objectives

  • by performing learning and/or support activities

  • within an environment, consisting of learning objects and services used in the performance of the activities.

  • Analogy with a play ….

Who does what when

Who does what, when?


But what do students and staff see

But what do students and staff see?

  • The diagram helps to identify roles, activities, acts, etc, easing the creation of an XML-based representation of the learning process;

  • Modelling is one thing, experiencing the learning design is another;

  • Today there is no IMS-LD player, but

  • An impression can be gained through the prototype EML player …

  • Warning: you are about to see Dutch content


Reflecting on ims ld concepts

Reflecting on IMS-LD concepts

  • People act in different roles

    • Students and facilitator

  • working towards certain objectives

    • Understanding the role of learning technology standards

  • by performing learning and/or support activities

    • Answering questions, discussing, reading, …

  • within an environment, consisting of learning objects and services used in the performance of the activities.

    • Material on standards, discussion forum, …


Having been introduced to eml and ld here s simple sequencing

Having been introduced to EML and LD, here’s Simple Sequencing …


Ims simple sequencing

IMS Simple Sequencing

  • Released March 2003

  • Will be part of SCORM 1.3

  • “Simple" because it includes a limited number of widely used sequencing behaviours, not because the specification itself is simple.

  • WARNING: some terminological differences with LD ahead


Eml ims learning design and ims simple sequencing

What Is Sequencing?

  • Predictable, consistent ordering and delivery of learning activities, in an instructionally meaningful manner, regardless of delivery environment

    • Designers/authors specify sequencing behaviors at design/authoring time.

    • Activities are sequenced at time of delivery depending on specified behaviors and the learner’s actions.

    • Sequencing behaviors are external from the content to enable greater degree of granularity and reuse


Problems that the ims sequencing specification is trying to solve

Problems that the IMS Sequencing Specification is Trying to Solve

  • Code for sequencing is embedded with code inside learning resources

  • Sequencing behavior is inconsistent in different delivery systems

  • Models of sequencing are proprietary or idiosyncratic

  • Models of sequencing behaviors and activities are poorly defined


Ss definition activity tree

SS: Definition: Activity Tree

  • LMS Sequencing behavior is described in terms of traversing the nodes of an activity tree to determine which activity to deliver to the learner


Ss content package structure

SS: Content Package Structure


Example sequencing behaviour

Example sequencing behaviour


Sequencing rules

Sequencing Rules

  • Rules have conditions which are based on Tracking Status (e.g. completed, satisfied, etc.)

  • Rules are evaluated at specific times during the various sequencing processes

  • Rules include:

    • Precondition Rules

      • If … then Disable this activity

      • If … then Skip this activity in flow mode

      • If … then Stop Forward Traversal

      • If … then Hide this activity from Choice

    • Exit Action Rule

      • If … then Exit

    • Post Condition Rules

      • If… then Continue

      • If… then Previous

      • If… then Exit All

      • If… then Retry

      • If… then Retry All


Example simple sequencing rules

Example Simple Sequencing Rules …

  • Satisfied – evaluates to True if the Objective Progress value of Objective Satisfied Status for the objective associated with the activity (indicated by Rule Condition Referenced Objective) is True.

  • Completed – evaluates to True if the Attempt Progress value of Activity Attempt Completion Status for the activity is True

Overview

  • A word or two on who I am

  • EML, Learning Design, Simple Sequencing

    • What are they?

  • Summary

  • Discussion


Ld and ss similarities

LD and SS similarities

  • Both offer sequencing mechanisms;

  • Both are packaged in the organizations section of an IMS Content Package

  • Both talk about learning activities;

  • Both talk about learning objectives;


It s not

It’s not …..

… because SS is single learner and LD is multi-learner and so there are things in LD which can’t be modelled in SS“SS does not address synchronization between multiple parallel learning activities … simple sequencing recognizes only the role of the learner” (SCORM 1.3)

Simple Sequencing

Learning Design


But is it

But is it …..

Learning Design

Can everything that can be done in SS also be done in LD?

Simple sequencing


Or is it

Or is it …..

Learning Design

Are there things in SS which can’t be done in LD?

Ims learning design is a framework

IMS Learning Design is a Framework

  • An IMS Learning Design can/is likely to:

    • Be packaged in an IMS Content Package

    • Use IMS Meta-data to describe various elements

    • Incorporate IMS QTI assessments

    • Use IMS Reusable Definition of Competency of Learning Objective to describe Learning Objectives

    • Map properties to IMS Learner Information Package elements

  • And may …

    • Include IMS Simple Sequencing …


Ss in ld

SS in LD

  • Sub-manifests

    • A content package using LD contains a sub-manifest that used SS, etc.

  • In an LD instance document.

    • inside the environments elements,

      • used to sequence learning objects and items contained in the learning objects.

    • within the learning object element

      • used to sequence items that are contained within a learning object.

  • Places requirements on runtime engine

Summary

Summary

  • LD is approved: learning and teaching are getting attention;

    • Opportunity to move away from designing for lone-learners reading from screens to focus on the performance of individual and group learning activities designed to attain learning objectives

  • Horses for courses:

    • LD and SS will have their own niches

  • IMS aware of terminology issues
