Index of definitions

Object

Definition

Example

Academic Calendar

An institution typically runs its business according to multiple cycles: registration cycles, fiscal year-ends, payrolls, admissions cycles.  The academic calendars typically define the cycles associated with enrollment and teaching

Academic year, term, semester

ACADEMIC RULE

A rule that constrains enrollment

Pre-requisite rule, admission rule, degree audit rule

CALENDAR

The archetype for the academic calendar

Fiscal calendar, academic calendar

Group

A collection of persons or groups (used in access management)

 

LEARNING OBJECT

An object of pedagogical value that is created and curated by the institution. May be re-used.  Access (read,write, modify) may be controlled by permissions assigned to roles just like any other object in the learning ecosystem.  Metadata, tags and usage data are associated with all Learning Objects.

Video, game, simulation, static content (PDF, HTML), quiz

LEARNING OBJECTIVE

Cognitive, psychomotor or affective objectives

 

Learning Plan

Learners' intended course of study

 

LEARNING RESULT

Result assigned to a learner upon completion of a Learning Unit

Grade, standing, degree

LEARNING UNIT

Any definition of a learning activity.  The abstraction used to isolate core attributes and relationships: learning objectives, organizational relationships, rules.  Learning Objects, by contrast, are the actual objects of pedagogical value that are used to accomplish the Learning Objectives of the Learning Unit.

Degree, course, major, lecture

LEARNING UNIT INSTANCE

Any scheduled offering of a Learning Unit

Course offering, scheduled lecture

Organization

A group with some formal TOR within an institution

University, college, high-school, department, faculty

Permission

A permission defines access to a resource

Access to lab equipment, access to library resources

PERSON

Person lies at the heart of the Learning Ecosystem.  A person may have multiple concurrent roles.

 

Resource

Any resource used in the learning process

Room, server, projector, file, books, articles, videos

Role

A role can be attached to a person or group

 


Detailed definitions


Academic Calendar
The actual names that are given to cycles vary from institution to institution: academic, year, term, semester, Lent term and Michaelmas term (Cambridge University). Increasingly, we find multiple concurrent cycles: graduate, undergraduate and continuing education may all run on different cycles. In many cases, the concept of a cycle itself may be inadequate. For example: we need something to run between 9:00 am November 11 and 3:00 pm November 14. The calendar object needs to handle all these cases.



Academic Rule
An academic rule is a rule that either:

  1. Constrains enrollment in a Learning Unit.
  2. Defines the conditions for the completion of a Learning Unit

They can be very simple as in:"In order to register in MATH200 you need to have completed MATH100". Or, that can be quite complex as in Degree Requirements.



A Learning Object:

  1. Has pedagogical value for the consumer
  2. Is re-usable
  3. Is searchable (across the Web)

Examples of Learning Objects include:

  1. Videos. A learning tool video platform allows parts to videos to be tagged, supports viewer analytics, supports access controls
  2. Static content: PDF, html, wikis
  3. Games
  4. Simulations
  5. Quizzes

Usage statistics (analytics) help inform the design of subsequent iterations of Learning Objects.  For example, if a video platform (eg Kaltura) records which parts of a video are most watched, this information can be used in the design of the next version of the video.


Learning Objective
Learning Objectives can be attached to any learning unit.

  1. A course can meet certain learning objectives.
  2. Learning objectives can b e specified for an individual lecture
  3. An entire degree program may have to meet certain learning objectives. This is especially important in the context of the certification of professional programs

Learning objectives are typically divided into:

  1. Cognitive
  2. Psychomotor
  3. Affective


Learning Plan
The Learning Plan can be short-term as in a timetable for the following term's courses. It can be long term as in the case of someone who want to become a medical doctor: stretching from Biology prerequisites all the way to residency requirements.



Learning Result
The term Learning Result covers 3 different concepts:

  1. A measure of success in meeting the learning objectives of the learning unit. This can be a grade (78%, 3.5, A+) or a standing (PASS, FAIL)
  2. A unit measure of the "amount learned" - "3 credits", "2 units"
  3. Recognition on a transcript of completion of a learning unit: BA major in History, CHEM 123


Learning Unit
The concept of a "Learning Unit" comes from Kuali Student. Canonical Learning Units are prescriptive in nature: MATH100 consists of differential calculus. HIST200 covers the ante-bellum South. Learning Units can be courses, programs, majors....indeed, anything to which the word "learning" can be applied. A Learning Unit ID is like a SKU. This allows for the creation of an inventory of Learning Units (a curriculum) without having to worry about the exact nature of the items.



Learning Unit Instance
This is the actual offering of a Learning Unit. It could be a Section, an Internship or a specific version of a program (offered between certain dates). Learning Objects (the actual things with pedagogical value: lectures, lecture notes, videos, quizzes) are made available for a given Learning Unit Instance. The learning Unit Instance is what the Learner enrolls in.



Person

Person lies at the center of the Learning Ecosystem data model. Often there are two possible relationships between a person and any other object in the model:

  1. Learner - Instructor
  2. "Advisee" - adviser
  3. Instructional designer - instructional consumer (learner)
