Lesson

A Lesson contains instructional content intended to be completed in a single day and/or class period. A middle or high school lesson might be intended for a 50 minute period (unless it was a designed for a block schedule). An elementary school lesson might be design for however much time the teacher generally allots to the subject (e.g., reading/writing might have more time allotted than science or art).

A lesson contains one or more Activities.

In many cases, the curriculum will describe a specific order that the Activities in a Lesson should go.

oer:Lesson meets the definition of schema.org/Course, i.e. it is "a sequence of one or more educational events and/or creative works which aims to build knowledge, competence or ability of learners". This means that resources that are lessons should be typed as oer:lesson and schema.org/Course. The schema.org learningResourceType property with a value of "lesson" should be used to indicate the type of course to systems that understand schema.org but not the OER Schema terms used by OCX.

Editor's Note

I know that lesson as a Course seems odd. If we find we don't need scheme.org's courseCode or coursePrerequisites properties we can just call a lesson a creative work.

Examples:

Properties

Property Type Description
From schema.org:Course -------------------- --------------------
courseCode Text The identifier for the lesson used by the course provider (e.g. CS101 or 6.001).
coursePrerequisites AlignmentObject or Course or Text Requirements for taking the Lesson. May be completion of another course, module, unit or lesson, or a textual description like "permission of instructor". Requirements may be a pre-requisite competency, referenced using AlignmentObject.
From schema.org:CreativeWork -------------------- --------------------
about Thing The subject matter of the content.
accessibilitySummary Text A human-readable summary of specific accessibility features or deficiencies, consistent with the other accessibility metadata but expressing subtleties such as "short descriptions are present but long descriptions will be needed for non-visual users" or "short descriptions are present and no long descriptions are needed."
audience EducationalAudience An intended audience, i.e. a group for whom the resource being described was created. Use the educationalRole property of the EducationalAudience object to state whether the intended audience is teacher, student, parent, etc. See the LRMI Educational Audience Role concept scheme for more values.
author Organization or Person The author of the lesson.
citation CreativeWork or Text A citation or reference to another creative work, such as another publication, web page, scholarly article, etc.
contributor Organization or Person A secondary contributor to the lesson
dateCreated Date The date on which the resource was created.
dateModified Date The date on which the resource was updated.
educationalAlignment AlignmentObject An alignment to an established educational framework. The alignment object can be used to provide information such as educational- (grade-) level of the lesson and competences being taught or assessed
hasPart CreativeWork Indicates a CreativeWork that is part of this lesson (in some sense). Inverse property: isPartOf.
inLanguage Language or Text The language of the content of the lesson. Please use one of the language codes from the IETF BCP 47 standard.
isBasedOn CreativeWork or URL A resource from which this lesson is derived or of which it is a modification or adaption.
isPartOf CreativeWork Indicates a CreativeWork that this lesson is (in some sense) part of. Inverse property: hasPart.
keywords Text Keywords or tags used to describe this content. Multiple entries in a keywords list are typically delimited by commas.
learningResourceType Text The predominant type or kind characterizing the lesson.
provider Organization The service provider, service operator, or service performer; the goods producer. Use to identify the Organization which is responsible for providing the educational input for the lesson, e.g. providing content, educational events, assessments, accreditation etc.
publisher Organization The organization credited with publishing the lesson.
timeRequired Duration Approximate or typical time it takes to work with or through this lesson for the typical intended target audience, e.g. 'P30M', 'P1H25M'.
typicalAgeRange Text The typical expected age in years of the learners on this lesson. For OCX the suggestion is to use a list to indicate a closed range of ages, e.g. ["9","10","11"], and values like "18-" for an open range.
From schema.org:Thing -------------------- --------------------
alternateName Text An alias for the lesson.
description Text A description of the lesson.
identifier PropertyValue or Text or URL The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, DOIs, UUIDs etc.
name Text The name [title] of the lesson.
url URL URL of the lesson.
From ocx -------------------- --------------------
ocx:material ocx:AssociatedMaterial Material assiociated with a resource which is SupplementalMaterial, ReferencedMaterial or SupportingMaterial
from oer:LearningComponent -------------------- --------------------
oer:doTask Task Which tasks are to be completed for a LearningComponent
oer:hasLearningObjective LearningObjective A LearningObjective gained as a result of an InstructionalPattern.
from oer:Resource -------------------- --------------------
forTopic Topic The Topic the resource is associated with.
cc:Work -------------------- --------------------
cc:license Text | License A Work has license a License (a subproperty of dc:license, the same as xhtml:license).
cc:morePermissions Text A related resource which describes additional permissions or alternative licenses for a Work which may be available.
cc:attributionName Text The name the creator of a Work would like used when attributing re-use.
cc:attributionURL URL The URL the creator of a Work would like used when attributing re-use.
cc:useGuidelines Text A related resource which defines non-binding use guidelines for the work.

Non-preferred properties

The following OER Schema properties should not be used as there are similar properties in schema.org:

OER Schema Property preferred schema.org equivalent
duration learningTime (from CreativeWork)
hasComponent hasPart (from CreativWork)
prerequisite coursePrerequisites (from Course)
parentOf hasPart (from CreativeWork)
childOf isPartOf (from CreativeWork)
all properties of oer:Thing all have equivalents in schema.org Thing

Example

Markup for https://pilot.unbounded.org/ela/grade-6/module-1/unit-2/lesson-8

  • JSON-LD

The following would be placed in a <script type="application/ld+json"> element in the HTML sectioning element that contained information about the lesson.

Note

The URIs used for the @ids are based on the URLs of the page that represent the module being described and its units with the addition of the #A fragment identifiers treating them as aggregate resources as described in the section on manifest structuring. This conforms with the requirement that different identifiers are used for CCM entities and the web pages that represent them, as described in the content model.

Note

In the case where the content of a unit is split over many HTML files, there is no requirement for the hasPart array shown in this example as this information would be provided by the manifest.

Editor's Note

Several parts of the original are omitted in the example in order to avoid repetition.

Note

Some of the parts are documents in a choice of digital format (encoding). If the HTML page for the Lesson is the only HTML page containing information about these documents then it is necessary to provide a full description of those documents in this page and their encodings. An example of such as description is provided under Properties of SupportingMaterial.
