Why it is important to us?


What is scorm
What is SCORM?

A software model

defines the interrelationship of course components, data models, and protocols such that content “objects” are sharable across systems that conform with the same model.

It is collection of specification adopted together for achieving some property of content like Accessibility, Adaptability, Affordability, Durability ,reusability, interoperability


What is scorm1
WHAT IS SCORM?

  • A REFERENCE MODEL: A set of profiles of standards and specifications that tells you how to do something useful

  • A SOLUTION: Solves the problem of separating Web-based training content from delivery systems

  • A STANDARD: Adopted by most commercial LMS products and required by

  • a DoD directive


Scorm and technology
SCORM and Technology

  • Content Aggregation Model

    • Metadata (from IEEE LOM 1484.12)‏

    • Content Structure (derived from AICC)‏

    • Content Packaging (from IMS)‏

    • Sequencing Information (from IMS)‏

  • Run-Time Environment

    • IEEE Application Programming Interface(1484.11.2)‏

    • IEEE Data Model (1484.11.1)‏

  • Sequencing & Navigation

    • Sequencing Information & Behavior(from IMS)‏


Scorm assumes
SCORM ASSUMES …

  • A particular content lifecycle (next slide)

  • Web-based content

    • Interactive (optional)

    • Static (designed ahead of delivery)

  • A single learner

  • Progress by objectives



Adl advanced distributed learning
ADL-Advanced Distributed Learning

Vision: 1997

  • “Provide access to the highest quality education, training and performance aiding, tailored to individual needs, delivered cost efficiently, anytime and anywhere”



Lms learning management system
LMS – Learning Management System

  • 2002:NOLP (NSTDA Online Leaarning Project) developed LMS SCORM 1.2

  • 2006: NOLP developed LMS 3.0, certified as LMS SCORM2004 (SCORM v1.3) by ADL

Content Aggregation Model

1. Learning Object Metadata (1484.12)

2. Content Packaging (IMS Specification)

Describe, export, transport and import

Run-Time Environment

3. Application Programming Interface

(1484.11.2)

4. Data Model (1484.11.1)

Launch, track, communicate learner info

Scorm content model components
SCORM Content Model Components

Assets:

building block of a learning resource.

text, images, sound, assessment objects or any other piece of data

More than one asset can be collected together to build other assets.

SCO:

A SCO is a collection of one or more Assets that represent a single launchable learning resource

tracked by an LMS

Sequence and navigation
Sequence and Navigation

  • Three ways for learners to traverse the Activity Tree

    • User Choice (“Choice”)‏

      • The learner can choose any activity in any order at any time

    • Flow

      • The learner can only move toward the ‘next’ or ‘previous’ activity – the system determines the activity to delivery

    • Forward Only

      • The “Previous” button is disabled.



Run time environment communicating with the lms

/* look up window hierarchy to find LMS provided API */

API.Initialize(“”);

var name = API.GetValue(“cmi.learner_name”);

API.SetValue(“cmi.score.scaled”, “0.9”);

API.Terminate(“”);

Initialize(“”)‏

SetValue(X, Y)‏

GetValue(X)‏

Commit(“”)‏

Terminate(“”)‏

GetDiagnostic(Y)‏

GetLastError()‏

GetErrorString(Z)‏

  • Must use JavaScript

  • There are only 8 functions that you may use

Where X = cmi data model element, Y = any string,

Z = error code

Scope of Adaptation

Limitation considered one prespecitive
Limitation considered..(one prespecitive)‏

limited adaptivity

Run time environment do setting of the predefined rule with key value pair only. We can not change these values at run time after SCO made.

This is again compact and it can not be used in different context by simple change. We have to make a new imsmanifest file for the changed context of learning.

Continue….

SCORM describes a solutions for systems, components and content interopability for learning

Data and Behavioral interoperability

SCORM does not extend beyond learning to management of learning

SCORM does not impose any pedagogical or assessment model

SCORM supports only limited pedagogical features


Continue4
Continue….

No communication across SCO’s

No access to other SCO’s

SCO has its own behavior

Using same hierarchy for structure, behavior and display

Learners are individual

It can not adapt learner experience without learner interaction

There is no concept of alternate resource although we can simulate it by making various navigation restrictions

There is nothing for picking some of resource from a collection of resource


Development in scorm
Development in SCORM

January 1999 — Executive Order 13111 signed tasking the DoD to develop common specifications and standards for e-learning across both federal and private sectors

January 2000 — SCORM Version 1.0

January 2001 — SCORM Version 1.1

October 2001 — SCORM Version 1.2

January 2004 — SCORM 2004 (1st Edition)

July 2004 — SCORM 2004 (2nd Edition)

June 2006 — Department of Defense Instruction (DoDI) 1322.26 Requiring DoD Use of SCORM

October 2006 — SCORM 2004 (3rd Edition)
