A learning object is "a collection of content items, practice items, and assessment items that are combined based on a single learning objective".^[1] The term is credited to Wayne Hodgins, and dates from a working group in 1994 bearing the name.^[2] The concept encompassed by 'Learning Objects' is known by numerous other terms, including: content objects, chunks, educational objects, information objects, intelligent objects, knowledge bits, knowledge objects, learning components, media objects, reusable curriculum components, nuggets, reusable information objects, reusable learning objects, testable reusable units of cognition, training components, and units of learning.

The core idea of the use of learning objects is characterized by the following: discoverability, reusability, and interoperability. To support discoverability, learning objects are described by Learning Object Metadata, formalized as IEEE 1484.12 Learning object metadata.^[3] To support reusability, the IMS Consortium proposed a series of specifications such as the IMS Content package. And to support interoperability, the U.S. military's Advanced Distributed Learning organization created the Sharable Content Object Reference Model.^[4] Learning objects were designed in order to reduce the cost of learning, standardize learning content, and to enable the use and reuse of learning content by learning management systems.^[5]

Definitions

The Institute of Electrical and Electronics Engineers (IEEE) defines a learning object as "any entity, digital or non-digital, that may be used for learning, education or training".^[6]

Chiappe defined Learning Objects as: "A digital self-contained and reusable entity, with a clear educational purpose, with at least three internal and editable components: content, learning activities and elements of context. The learning objects must have an external structure of information to facilitate their identification, storage and retrieval: the metadata."^[7]

The following definitions focus on the relation between learning object and digital media. RLO-CETL, a British inter-university Learning Objects Center, defines "reusable learning objects" as "web-based interactive chunks of e-learning designed to explain a stand-alone learning objective".^[8] Daniel Rehak and Robin Mason define it as "a digitized entity which can be used, reused or referenced during technology supported learning".^[9]^[10]

Adapting a definition from the Wisconsin Online Resource Center, Robert J. Beck suggests that learning objects have the following key characteristics:

Learning objects are a new way of thinking about learning content. Traditionally, content comes in a several hour chunk. Learning objects are much smaller units of learning, typically ranging from 2 minutes to 15 minutes.
Are self-contained – each learning object can be taken independently
Are reusable – a single learning object may be used in multiple contexts for multiple purposes
Can be aggregated – learning objects can be grouped into larger collections of content, including traditional course structures
Are tagged with metadata – every learning object has descriptive information allowing it to be easily found by a search^[11]

Components

The following is a list of some of the types of information that may be included in a learning object and its metadata:

General Course Descriptive Data, including: course identifiers, language of content (English, Spanish, etc.), subject area (Maths, Reading, etc.), descriptive text, descriptive keywords
Life Cycle, including: version, status
Instructional Content, including: text, web pages, images, sound, video
Glossary of Terms, including: terms, definition, acronyms
Quizzes and Assessments, including: questions, answers
Rights, including: cost, copyrights, restrictions on Use
Relationships to Other Courses, including prerequisite courses
Educational Level, including: grade level, age range, typical learning time, and difficulty. [IEEE 1484.12.1:2002]
Typology as defined by Churchill (2007): presentation, practice, simulation, conceptual models, information, and contextual representation ^[12]

Metadata

One of the key issues in using learning objects is their identification by search engines or content management systems.^[13] This is usually facilitated by assigning descriptive learning object metadata. Just as a book in a library has a record in the card catalog, learning objects must also be tagged with metadata. The most important pieces of metadata typically associated with a learning object include:

objective: The educational objective the learning object is instructing
prerequisites: The list of skills (typically represented as objectives) which the learner must know before viewing the learning object
topic: Typically represented in a taxonomy, the topic the learning object is instructing
interactivity: The Interaction Model of the learning object.
technology requirements: The required system requirements to view the learning object.

Mutability

A mutated learning object is, according to Michael S. Shaw, MSc (2003), a learning object that has been "re-purposed and/or re-engineered, changed or simply re-used in some way different from its original intended design".^[14] In other words, educational content or learning materials, initially designed for a specific domain, may be intentionally or unintentionally, repurposed or applied, or become relevant in some significant way to the learner or situation, even though it is from a totally different domain. This interpretation aligns with the idea that the inherent properties of the learning objects remain constant, but their application becomes beneficial and adaptable across diverse domains. Shaw's speculative interpretation suggests an intrinsic stimulation of cognitive flexibility and creative reuse of learning resources for the learner. Shaw also introduces the term "contextual learning object", to describe a learning object with high specificity, that has been "designed to have specific meaning and purpose to an intended learner". This may be useful if the intent involves just-in-time learning and the individual needs of individual learners.

Portability

Before any institution invests a great deal of time and energy into building high-quality e-learning content (which can cost over $10,000 per classroom hour),^[15] it needs to consider how this content can be easily loaded into a Learning Management System. It is possible for example, to package learning objects with SCORM specification and load it in Moodle Learning Management System or Desire2Learn Learning Environment.

If all of the properties of a course can be precisely defined in a common format, the content can be serialized into a standard format such as XML and loaded into other systems. When it is considered that some e-learning courses need to include video, mathematical equations using MathML, chemistry equations using CML and other complex structures, the issues become very complex, especially if the systems needs to understand and validate each structure and then place it correctly in a database.^{[citation needed]}

Criticism

In 2001, David Wiley criticized learning object theory in his paper, The Reusability Paradox which is summarized by D'Arcy Norman Archived 2021-05-02 at the Wayback Machine as, If a learning object is useful in a particular context, by definition it is not reusable in a different context. If a learning object is reusable in many contexts, it isn’t particularly useful in any. In Three Objections to Learning Objects and E-learning Standards Archived 2021-04-15 at the Wayback Machine, Norm Friesen, Canada Research Chair in E-Learning Practices at Thompson Rivers University, points out that the word neutrality in itself implies a state or position that is antithetical ... to pedagogy and teaching.
