Assessment

FREMA Overview

Overview

You’ve seen the system – now is our chance to tell you what we hope we have achieved and your chance to tell us if we have achieved it!

• Introduction to FREMA

• Anatomy of a Reference Model?

• Views on the Model

• Debrief and Feedback

Background

• What is FREMA?– JISC funded Project between Southampton, Strathclyde

and Hull– Part of the e-Learning Framework (ELF) effort

• What is the ELF?– Service Oriented Architecture for e-learning systems– Layered Web Services (Domain services over Common

Services)– Dynamic and evolving

Background

• FREMA will develop a Reference Model for the Assessment domain– Supporting design-time activities– Supporting run-time activities– Virtual organisations and lifelong learning

• What is a Reference Model?– A description of how services behave within a particular

domain– A community resource

Assessment and ELF

• Not enough to describe and define these services• Need a proper audit trail of decision making• Start by defining the domain • Work up through the services to a reference

implementation• This is an ELF Reference Model

Anatomy of a Reference Model• Domain Definition

– Overview of the domain, and how projects and standards fit within it

Gap Analysis

Reference Impl’

• Identifying Common Usage Patterns– Scoping the FREMA Project

• Gap Analysis– Mapping of Use Cases to the Services in ELF

• Service Profiles– Formal descriptions of those services

• Reference Implementation– Of key/core services– Examples– Validation– Resource

Common Usage Patterns

• Developing Use Cases– Formal descriptions of usage patterns

What does it look like?

• An evolving, cross-referenced, searchable web site

• Indexed resources and narrative descriptions of the domain• UML Use Cases and Scenario documents• Service descriptions, narrative and WSDL• Service implementations to download (Java/.NET)

• Different gateways into the model according to how you want to use it

Common Usage Patterns

Views on the Model

• Use the Reference Implementation– Build on some or all of the developed services

• Use the Service Profiles– To develop your own services that will fit into the framework

• Use the Use Cases– To help understand usage patterns within the domain– Develop new Service Profiles and thus Services

• Use the Domain Definition– To develop a context for your own work– Understand how existing work fits together– Identify standards– Locate experts

Common Usage Patterns

Interconnected Resources• Schema of resources

and relationships between them (ontology)

• Used to generate dynamic pages for each resource

• Can show secondary data (like how much info we have on a resource)

Concept modelling

• Schema level means you can find things if you know what to look for. Concept maps help users find new things.

• What mental models might these and other actors use to orient their searches?

• How do they visualise the assessment domain?

• Concepts of the domain reflect community practice and knowledge

• Can be dynamic and evolving

Debrief and Feedback

• Thanks for filling out our questionnaire– Some initial results…

• Now is your chance to give us some direct feedback– Did the reference model support you in your role?– How could it be improved?– What other tools/views might you need?
