Living Systems Model • Overview • Why a new ID Model? • Living Systems Model Phases • Examples
Living Systems Model Why a new ID Model? • Requirements of Web-based Systems • Develop web-specific instruction • Dynamic, changing content • Open-ended system (external link) • Web-specific development processes • Web-specific project teams
Living Systems Model Why a new ID Model? • Traditional ID Models • Often delivery medium-independent • Focus on concept of “final product” • No formal mechanism in place for dynamic changes in requirements and needs of users
Living Systems Model Why a new ID Model? • Knowledge Management Systems • Scenario: To solve a work-related problem, user retrieves cases, constructs solution, adds new case to KM system • Result: Dynamically changing system, responding to user’s needs • Problem: Formal process to respond to the changes in the system: new services, features, etc.
Living Systems Model Why a new ID Model? • Living System Approach • Changes in the system are assumed • Formal mechanisms in place to accommodate change and growth • System is viewed as ‘living system,’ not as final product • Digital nervous system features

Living Systems Model 501 Communication OLIT 501 ISD Online Course
Living Systems Model Interface Design Approach • Definition Human-Computer Interface • Interface not merely in charge of communication with the user, but is an • Expression of the deliberate decisions by the instructional designer to include features in the conceptual model of the application that support different cognitive processes of learning
Living Systems Model Instructional Strategies • Definition • Overall plan governing instructional content and process consisting of a set of decisions that result in a plan, method, or series of activities aimed at obtaining a specific goal • Purpose • Organize instruction to support learner's cognitive processes of attention, encoding, and retrieval of information
Living Systems Model Instructional Strategies • Organizational Strategy • Content, Sequencing of instruction • Form of presentation • Delivery Strategy • Instruction medium used • Grouping of learners • Management Strategy • Scheduling and allocation of resources • (Reigeluth, 1983)
Living Systems Model Instructional Events • Gagné & Briggs • Gaining attention • Informing learners of objective • Stimulating recall of prerequisite learning • Presenting instruction • Providing learning guidance • Eliciting performance • Providing feedback • Assessing performance • Enhancing retention and transfer

Living Systems Model Interaction Design • General Considerations/Issues • Task Analysis Results as Basis for ID • Cognitive TA Results as Basis for ID • Standards/Conventions for field • Standards/Conventions for WWW • Use of Metaphors
Living Systems Model Interaction Design • Instructional Considerations/Issues • Philosophy of Instruction: Behaviorist/Cognitivist/ Constructivist Approach • Level of Learner Control, Choice • Cognitive Load (Overhead) Imposed by Interaction
Living Systems Model Scenario Interaction Design Evaluation • Application of Pattern Language • Articulates and communicates the design of the entire system in a coherent, formal way (Alexander, Ishikawa & Silverstein, 1977; Tidwell, 1999) • Units of language: design rules, or patterns, that capture the solutions to specific issues or problems in the design process in a particular context, and are therefore neither too abstract nor too specific
