Information technology -- Sharable Content Object Reference Model (SCORM®) 2004 3rd Edition -- Part 4: Sequencing and Navigation Version 1.1

There are several key concepts that are introduced in the SCORM SN book. The book

covers the essential Learning Management System (LMS) responsibilities for sequencing

content objects (Sharable Content Objects [SCOs] or Assets) during run-time and

allowing SCOs to indicate navigation requests. In addition, guidance is offered for

providing navigation controls to learners. General subjects discussed include:

• Sequencing Concepts and Terminology (e.g., Learning Activities, Activity Trees,

Clusters)

• Sequencing Definition Model (i.e., detailed descriptions and requirements of the

sequencing information that can be applied to learning activities)

• Sequencing Behavior Model (i.e., detailed descriptions of LMS behaviors to

prescribed sequencing information and learner’s experience with learning content)

• Navigation Controls and Requirements

• Navigation Data Model

Communication between content and LMSs facilitates use of SCORM Sequencing and

Navigation to present content to learners based on learner choices and performance at

run-time. This communication also enables LMSs to track learner completion and

progress while content is presented to the learner. This book describes in detail how

sequencing behaviors are applied to track learner progress.
