Instructional modeling

� Process of producing instructional models (IM)

� IM can be teaching method, assessment method, conrete teaching and assessment units.

� Involves different artifacts and tools

Many available standards and specs for different artifacts, e.g. SCORM or IMS LD for activities, IMS QTI for assessments, IMS CP for content packaging, LOM or DC for metadata, IEEE RCD for outcome definition …

Objective : Standards -based Sharing

� Formal abstract descriptions of teaching and/orlearning situations – interoperability and reuse!

� Many tools that implement a standard modelinglanguage (Reload, ReCourse, MOT+, ASK-LDT, etc)

� Many tools enable integrated commnuity features(eg CompendiumLD, LAMS etc)

� The intersection is very small

Objective: Standards-based implementation ofcommunity use cases seamlessly within the modelingtool

“Intelligent” LOM record construction

“Electronic forms must die!”

� Title (1.2), general description (1.4) from IMS LD manifest

� Lifecycle (2.*), meta-metadata (3.*) from OICS/OpenGLM user data

� Educational description (5.10) from activity descriptions

� Resource type (5.2) is LD if content objects attached, otherwise TM

� Relations (7.*) extracted from OICS learning objects used and TMs implemented

� Intended learning outcomes (ext. 5.12) from IEEE RCD compliant outcome definitions

Application

Example scenario:

Reuse existing instructional models to develop a new LD for an “Academic writing” course

End-user evaluation

2 universities, 11 users

Perform desgin task, then structured interview

Findings:– Work integration: real-life relevance? � portfolios, workload calculation

– Training: help required� staff training

– Terminology: sometimes confusing� adapt to institution

– Content quality: unsure, lack of info� quality controlledrepositories

– Sharing & development: well received� discourse on teaching
