3Abstract
- Learning object (LO) first popularized by Wayne
Hodgins in 1994. - Serious lack of conceptual clarity and reflection
in the multitude of definitions and uses of LOs. - Objectives
- Assess current definitons and uses of LOs
- Articulate foundational principles for developing
concept of LOs - Provide methodology and broad set of guidelines
for creating LOs
4Movements in the Learning Object Economy
- Efforts towards facilitating a common method for
identifying, searching and retrieving Learning
Objects (LOs). - Question What may the common metadata elements
be? - Examples of groups working on such question are
- IEEE Learning Technology Standards Committee
(LTSC) Learning Object Metadata Working Group. - IMS Global Learning Consortium, Inc.
- The Dublin Core Metadata Initiative
- Existing a broad understanding about the
functional requirements of LOs - Accessibility the LO should be tagged with
metadata so that it can be stored and referenced
in a database - Reusability once created, a LO should function
in different instructional contexts - Interoperability the LO should be independent of
both the delivery media and knowledge management
systems
5Multiple Definitions of Learning Objects
- Definitions of LOs (samples)
- Draft Standard for Learning Object Metadata v6.1
- LO is defined as any entity, digital or
non-digital. Non-digital objects such as computer
hardware and digital objects like images enjoy
the same conceptual status, thereby making it
impossible to use the term Learning Object in a
meaningful way. - Wiley, David. A. (2002)
- LO is any digital resource that can be reused to
support learning. a broad characterization
classifying every digital asset as a LO. - Wisconsin Online Resource Center
- Definition includes the arbitrary imposition of
time - http//www.wisc-online.com/Info/FIPSE20-20What
20is20a20Learning20Object.htm - L'Allier, James J. (1997)
- LO is the smallest independent structural
experience that contains an objective, a learning
activity and an assessment."
6Towards a Concept of the Reusable Learning Object
- Foundation Learning and Reusability
- Learning Intention
- Form as the framework that sets a media asset on
the path to becoming a LO - Relation that occurs between the user and
computer interface - Form and relation provide a mechanism for the
internal constitution of a LO - The LO is a totality that combines its digital
element and an exposition - Reusability accords value to LO
- LOs should be predisposed for reuse by multiple
developers in various instructional contexts - LOs should not favor one or other instructional
methodology - It is through exchangeability /reusability that
the LOs acquire value - Based on theese foundational principles LO can be
defined as - A Learning Object is an independent and
self-standing unit of learning content that is
predisposed to reuse in multiple instructional
contexts -
7Creating Learning Objects
- LO should not be coded by any specific teaching
methodology or instructional theory - Genuine reusability and optimum functionality of
a LO can be achieved only when the LO attains a
high level of abstraction - Although LO is abstract, it can be understood and
shared among users - Several LOs should be put together as words in a
sentence - Granularity - the size of a LO
- If a LO consists of more then one idea, one of
these should be the main idea and the others
should be derived from it or be dependent on it. -
- Composition
- The formal composition of a LO is the arrangement
of elements (text, image, video, animation,
glossary, assessment, multimedia, etc.) - LO should be a combination of multiple elements,
facilitating learning based on learners' choices
and learning characteristics.
8Developing Learning Objects
- Two processes Conceptualization and
Collaborative development -
- Conceptualization
- LO modeling requires a double vision
- Global understanding of curricula
- to conceive a content object as part of larger
whole - Micro vision to create content as standalone
information for it to function as a reusable
object -
- Framework should proceed in three steps
- 1 Selecting a topic or theme
- 2 Identifying different levels and depths -
providing an intensity map - 3 Design LOs for a varied level of instruction
-
- Collaborative development
- The role of experts from all fields is crucial
for the successful development and use of LOs - Knowledge experts should develop only 'events' of
knowledge that can combine with other 'events' to
develop into a 'program' on demand.
9Standards and Specifications for Developing LOs
- LO development is a collective enterprise among
- The programmers - creating the information space
- The graphic designers - design and develop
interfaces to facilitate the management - The subject experts - providing the
ideas/concepts stored as information bits - A commonly agreed on standard enables genuinely
sharable and reusable content objects - Technical standards
- Interoperability of LOs - selection of language
for producing LOs - Editorial Requirements
- Agree on editorial standards to ensure the
consistency of language across the LOs - Stylistic Considerations
- Specifications for use of color, fonts, and
layout of images and text - Several interface and stylistic environments that
are user-controlled
10Learning Objects and Electronic Books
- The role of LOs in the construction of e-books
- Tension between the e-book and the material book
- Three levels of the book's existence Concept -
Object - Metaphor - Conceptually a book is a compendium of printed
pages turned by the reader - E-book is organized like volumen through which
one scrolls - The Book as a three-dimensional object offers a
plurality of sensual experiences - The e-book as a visual mode of presentation, is
limited since it does not offer the same sensual
experience as the material book - Life as a book one of metaphors arrived from
our long relation with the book - E-books belong to the information sphere which
space is temporal - The fundamental differentiation with the book
should become the foundation for building the
e-book - E-books should create a unique form of new and
different experiences for its audience
11Conclusion
- LOs are the most meaningful and effective way of
creating content for e-learning - The current definitions and practices of LOs are
confusing and arbitrary - They will never be able to avail themselves of
the flexibility, scalability and speed offered by
information technology - Necessary with a commonly accepted, accurate and
functionally effective definition of a LO - Establish a concept of the LO that clearly lays
out the principle basis on which it is founded - Need to reengineer the design and development
process of LOs - Developers should embrace a multidisciplinary and
cooperative model of development
12ITCOLE ProjectDesigning Innovative Tecnology for
Collaborative Learning and Knowledge
BuildingLeinonen et al. (2001)
- Abstract
- Describing pedagogical background and design
rationale of ITCOLE (Innovative Technology for
Collaborative Learning) software. - Central metaphor of the ITCOLE system is that of
shared electronic workspaces which students and
teachers use for asynchronus and synchronus
collaboration. - The system will provide tools for community
building as well as include awareness tools that
help users to manage their joint knowledge
building by providing real time information on
various aspects of collaboration. - ITCOLE software is avaliable free of charge in a
downloadable pilot version titled Future Learning
Environment 2 (Fle2) (now Fle3).

13Introduction
- Collaborative knowledgebuilding is one of the
most promising innovations to increase quality of
education with the help of modern collaborative
technology - ITCOLE system will be designed to provide tools
to facilitate the development of the students
skill of collaborating. - The functionality and the interface of the system
will be derived from pedagogical considerations
and can be adapted to different school
environments. - Knowledge Building (KB) environments differ
substantially from other networked learning
environments, as they are designed to facilitate
collaborative KB within a local or virtual
learning community. - KB learning environments must be easy to use, and
made accessible to teachers. - The project focuses on crossing boundaries
between software developers, pedagogical
researchers, and the users of KB technology -
teachers and students.
14Description of the ITCOLE software
- The pilot version FLE2 (now 3) is cross platform
and HTML based for end users - The ITCOLE/ Fle3 environment will contain several
tools - Virtual Web Top storing and sharing documents,
java applets etc. - KB module facilitates between-user interaction,
multiple discussions - Jam session encourages free flow of ideas
allows experimentation - Meeting room collaborative multi-user
applications (whiteboard, chat etc.) - Library - store, publish and browse diff.
learning materials - Provide external structures that help a student
to participate in expert like processing of
knowledge without increasing the cognitive
processing load. - Participation in depth learning, scaffolding the
users - Tools for students to record and visually
represent their activity - Challenge design interface helping users to
manage knowledge produced - Important challenge of ITCOLE is to design tools
that help to represent progress of discussions by
graphical means.
15Design Objectives of the ITCOLE software
- The objective for ITCOLE is to build a
pedagogical interface for educational use - The objective can be divided into three main
aims - Scalability universal access for different
user/browser configurations - Usefulness - full set of features to enable
collaborative KB - system functionality - Usability user friendly and attractive
graphical design flexible and customizable - Some screenshots from Fle3 http//fle3.uiah.fi/

16The ITCOLE System Architecture
- Shared workspaces are the primary means of
collaboration provided by ITCOLE - The overall system architecture
- Objects in the workspace can be
- accessed and manipulated
- Users may up/download etc.
- Around the kernel will be a set
- of additional features and tools
17Shared workspaces
- Primary features built into shared workspace
component of the ITCOLE system - Joint production of multimedia information in
distributed environments - Comprehensive information about activities within
the workspaces - Textual representation of information as well as
varied graphical representations - Support the publication of the results of
collaboration processes - Components for organizing and managing the
collaborative learning process
18Synchronous collaboration tools
- Synchronous communication provides a means for
participants - To interact socially
- Learn about each other
- Engage in social bonding
- Creating the sence of community needed for
engaging in intensive KB - To support this creation, these applications will
be integrated in the ITCOLE tools - Whiteboards visualized by all collaborators
simultaneously - Presenters must contain features that permit
highlighting of particular objects - Chats must indicate name of users
- The tools for synchronous communication can be
located in avatar-world - E.g. Virtual Room Videoconferencing System
developed in CERN - http//en.wikipedia.org/wiki/Virtual_Room_Videocon
ferencing_System
19Assessment Tools and Tutorware
- ITCOLE system will also support more instruction
based learning scenarios - Assessment tools will
- Allow self-evaluation of students
- Enable feedback between students and teachers
- Create a suitable infrastructure for progress
tracking and learning improvements based on
feedback information. - Function simultaneously as a means for tutor or
teacher to monitor participation of students in
their interaction and communication. - Tutorware will
- Allow the adaptation to the requirements and
interests of each student - Support teachers in collecting and creating
educational objects like - simulations - problem solving tasks other
teaching materials
20Pedagogical Evaluation and Testing
- Information and Communication Technology (ICT) is
used to - Build up social structures that encourage
learning and reflective discourse - Help students and teachers gain knowledge and to
deepen understanding - Evaluation process focuses on
- How the software facilitates learning in various
educational settings - Developing and analyzing innovative ways of using
ITCOLE software for facilitating in-depth
learning from elementary to high school. - The softwares technical as well as pedagogical
usability and functioning. - Field test will continually provide feedback for
design and development. - Second part of field test will involve
experiments in scaling up networked learning - Investigators will examine and demonstrate
- Collaboration with national school authorities
- Involve a relatively large number of primary and
secondary schools - Several participating countries
21Can deep thinking and collaboration with
fellow students increase motivation in the
classroom?
Teachers do not just need basic information
and communication technology training, but they
need to reflect on how they can make use of the
technology in their own teaching.
