Moodle 2.0

Note: This page outlines ideas for the Competencies feature planned for Moodle 2.0. It's a specification under construction! If you have any comments or suggestions, please add them to the page comments.

Overview

To model the range of different types of competency frameworks used by organisations, competencies in Moodle 2.0 needs to go further than the 1.9 outcomes architecture allows.

Goals

  1. Measured amount of abstraction
    • Allow "admins" to specify the type of hierarchy (hierarchy, tags, or hybrid)
    • Allow "admins" to define terms to describe the structure
    • Allow "admins" to specify parent-child and relations between terms
    • Allow "admins" to create as many levels as necessary
    • Allow "admins" to name/describe a level with custom fields to meta data for nodes at the level
  2. Easy navigation
    • Allow "admins" to view the competency structure and terms
    • Allow "admins" to easily add new competency terms and meta-data
  3. Visibility within courses
    • Allow "course creators" to add competencies to a course (much the same way outcomes can be added to a course in 1.9)
  4. Portability
    • Allow "admins" to export competency terms and structure in some easily understood format
    • Allow "admins" to import competencies from another Moodle instance
    • Allow "admins" to setup a sync of competencies with external systems
  5. Assigning evidence
    • Allow "admins" to assign to a competency:
      • One or more course outcomes from one or more courses
      • One or more course completions (e.g., when completing course A, course B, and course C)
      • One or more activity completions (e.g., when completing activity x in course A and activity y in course B, and activity z in course C)
      • An aggregate result threshold for a question category (i.e., an evaluation or assessment using mod/quiz, mod/scorm, etc)
      • Electronic evidence (e.g., a file containing a diploma, certificate, report)
      • Observation (e.g., a comment / testimony / reference)
  6. Specifying proficiency levels
    • Allow "admins" to assign to a competency:
      • A proficiency level (i.e., competency scale value)
      • Existing course completion criteria for a course
      • Existing activity completion criteria for an activity
      • Alternative course completion criteria
      • Alternative activity completion criteria
      • Aggregate result threshold for a question category
  7. Specifying weights
    • Allow "admins" to assign to a weights to each competency evidence or competency term
  8. Scalability
  9. Extensibility

General requirements

  1. We'll need to access and use the existing site-wide Outcomes Outcomes tables
  2. We'll need to use the tables that indicate completion status for courses (these are not yet in place) Course Completion
  3. We need to get aggregate information about the course outcomes and aggregate grades for each user from the gradebook API

Definitions

Scale: A way to measure a competency. Examples:

"Below average, Average, Above average"
"Not competent, Competent"

Competency term: A competency category or tag used for organising one or more competencies in a hierarchy or taxonomy. Examples:

top-level term: "Competency Area" (e.g., "Reading Comprehension")
   -> child term: "Competency" ("Responding to Text")
                -> child term: "Sub-competency" ("Initial Understanding of Literary Text")
                             -> child term: "Descriptor" ("Demonstrate initial understanding of elements of literary texts (including text read aloud, reading independently")

Competency: A measurable knowledge, skill, ability, attitude or other learning-related characteristic which a student may have. A competency may be associated with one or more competency terms. Examples that could be attached to the example "Descriptor" term above:

"Identifying characters in a story"
"Retelling the beginning, middle, and end of a story"
"Responding to simple questions about a book's content"

Competency evidence type: A form of evidence that can be accepted as evidence that a competency has been achieved. Examples:

Observation
Quiz grade
Course completion
Activity completion
Certificate
Evaluation results
File (diploma)

Competency evidence: A competency can be measured by one or more competency evidence types. Evidence can be stated to include the evidence type, evidence date, and measured value. Examples:

"Observation - Teacher - Above average - 4:00pm May 28, 2009"
"Observation - Spanish Language Proficiency Interview - 4:00pm May 28, 2009 - Rating 4 out of 5"
"Quiz - 4:00pm May 28, 2009 - Grade 90% out of 100%"
"Certificate - Public Speaking Institute - 4:00pm May 28, 2009 - Passed.
"File - College Diploma - 4:00pm May 28, 2009 - Bachelor of Science Computer Science"

Expected proficiency level: The required rating (based on a scale) or grade for a competency. Examples:

"Average"
"5"
"50%"
"Passed"

Measured proficiency level: A user's observed, scored, reported proficiency level for a competency.

"Above average"
"8"
"80%"
"Passed"

Competency weighting: Child competencies can be assigned weights which can be aggregated. Examples:

"Communication"
    -> child "Written Communication - weight: 60/100"
    -> child "Oral Communication - weight: 40/100"

User interface

Individual learning plan

  1. Each user can have a set of either courses to be completed, competencies to be achieved, or a mixture of both. These comprise a user's individual learning plan (IDP).
  2. Each user's IDP will show:
    1. Completed courses
    2. Progress toward courses which are not yet complete. This would be similar to view of the course progress completion report for the user across the incomplete courses.
    3. Competencies achieved. This will include the competency terms and meta data made visible to the user, as well as the evidence info (type, date, ratings and grades).
    4. Competencies not yet achieved. This will also include the competency terms, meta data made available to the user, as well as the expected proficiency levels for each competency.
  3. Each user can see a list of all his/her courses and competencies as a "transcript" or "record of learning."

Plugin architecture

Competency evidence type plugins

Each type of evidence will need its own methods for interacting with the competency architecture and will need to interact via a base competency evidence API. Below are the item types.

  • Observation
  • Course completion
  • Course grade
  • Activity completion
  • Activity module grade
  • File

Report plugins

Similar to the gradebook, we need to allow development of report plugins for competencies.

Import/Export plugins

We need to be able to import and export data related to competencies.

Competency framework import/export A competency framework should be able to be exported using an appropriate format in either xml and csv file format. There are some standards on exchanging competencies including:

  • IEEE P1484.20.1 Standard on Reusable Competency Definitions and the IEEE Draft Standard on Simple Reusable Competency Map
  • ISO/IEC PDTR 24763 Conceptual Reference Model for Competencies and Related Objects

Competency evidence import/export

There are a variety of standards for exchanging competencies evidence including:

  • IMS Reusable Definition of Competency or Educational Objectives Spec (RDCEO)
  • IMS Learner Information Package Spec (LIP)
  • HR-XML Competencies (Measurable Characteristics) Recommendation, 2007 April 15

IMS RDCEO and LIP recommend formats as shown in the examples below (more IMS RDCEO here and IMS LIP home). Special thanks to Sarveswaran Kengatharaiyer (GSOC 2008 student for the Moodle Progress Tracker project) who developed these examples.

rdceo.identifier = rdceo434323
rdceo.title = Identify verbs in simple sentences
rdceo.description = “Identify verbs in simple sentences”
rdceo.definition.statement.
   statementid = 123
   statementname = Always
   statementtext = Scale
   statementtoken = scl55435
rdceo.definition.statement.
   statementid = 124
   statementname = Never
   statementtext = Scale
   statementtoken = scl55436
rdceo.definition.statement.
   statementid = 125
   statementname = Sometimes
   statementtext = Scale
   statementtoken = scl55437

lip.contenttype.referencial.sourceid.id = jenney_profile
lip.identification.cotenttype.referential.indexid = id123
lip.identification.name.partname.typename=Jenny 
lip.competency
   cotenttype.referential.indexid = j123
   exrefrecord = rdceo434323
   description = Always

HR-XML recommends a format like shown below in an example which uses recursive competencies (more here).

<Competency name="Communication Skills">
      <Competency name="Written Communication Skills">
            <CompetencyEvidence name="WRITTENTEST1-A" dateOfIncident="1995-01-01" lastUsed="2000-01-01">
                   <NumericValue minValue="3" maxValue="5" description="SEP-equivalent Skill-Level Range">5</NumericValue>
            </CompetencyEvidence>
            <CompetencyWeight>
                   <NumericValue minValue="0" maxValue="100">35</NumericValue>
            </CompetencyWeight>
      </Competency>
      <Competency name="Oral Communication Skills">
            <CompetencyEvidence name="ManagerObservation" dateOfIncident="1996-01-01" lastUsed="2000-01-01">
                   <NumericValue minValue="1" maxValue="5" description="Company XYZ Skill Range">5</NumericValue>
            </CompetencyEvidence>
            <CompetencyWeight>
                   <NumericValue minValue="0" maxValue="100">65</NumericValue>
            </CompetencyWeight>
      </Competency>
</Competency>

Upgrade from 1.9

The outcomes and scales architecture introduced in Moodle 1.9 provide a basic foundation for competency management. One or more scales can be defined on a site-level, and custom scales can be defined at the course level. Outcomes can be defined at a site-level as standard outcomes, and standard outcomes can be added into courses. Custom outcomes can also be created within courses. Each outcome is linked to an activity via the settings page or via the controls for an existing outcome on the grader report page.


grade_outcomes - site-wide outcomes

Site wide outcomes will need to be imported into the competency_terms table.

From Table From Field From Value To Table To Field To Value
grade_outcomes id null competency_terms id null
grade_outcomes courseid null competency_terms courseid null

grade_outcomes usermodified not null competency_terms usermodified not null


grade_outcomes - custom course outcomes

Custom course outcomes will also need to be imported into the competency_terms table.

From Table From Field From Value To Table To Field To Value
grade_outcomes id null competency_terms id null
grade_outcomes courseid not null (e.g., 2, 3) competency_terms courseid null
grade_outcomes shortname not null competency_terms shortname not null

grade_outcomes timecreated not null competency_terms timecreated not null
grade_outcomes timemodified not null competency_terms timemodified not null
grade_outcomes usermodified not null competency_terms usermodified not null


grade_outcomes_courses

Grade outcomes in a course become an evidence item (itemtype='course') for a competency and get moved to the competency_evidence_items table.

From Table From Field From Value To Table To Field To Value
grade_outcomes_courses id not null competency_evidence_items id? not crucial not null
grade_outcomes_courses courseid not null competency_evidence_items instanceid not null
grade_outcomes_courses outcomeid not null competency_evidence_items competencyid not null


grade_items - course outcomes

Course outcomes need to be entered as a competency evidence items (type="course") for a competency and get moved to the competency_evidence_items table.

From Table From Field From Value To Table To Field To Value
grade_items id not null competency_evidence_items id? not crucial not null
grade_items itemname not null competency_evidence_items name not null
grade_items itemtype course competency_evidence_items itemtype course
grade_items itemmodule null competency_evidence_items itemmodule null
grade_items iteminstance not null (1,2) competency_evidence_items iteminstance not null (1,2)


grade_items - activity outcomes

Grade outcomes in a course become a course 'type' allowed evidence for a competency and get moved to the competency_evidence_allowed table. We also need to use the value "course" for the evidence 'type' field.

From Table From Field From Value To Table To Field To Value
grade_items id not null competency_evidence id? not crucial not null


grade_grades

In 1.9, course outcomes appear in the grade_items when they are linked to an activity. Only activity outcomes appear as graded in grade_grades. The activity outcomes need to appear as an entries in competency_evidence_items table and the grade in the competency_items table.

From Table From Field From Value To Table To Field To Value
grade_grades id not null competency_items id not null
grade_grades itemid not null competency_items itemid not null
grade_grades userid not null competency_items userid not null
grade_outcomes scaleid not null competency_items scaleid not null
grade_grades finalgrade not null competency_items scalevalueid not null


We also need to add an entry for the user in the competency_evidence table.

From Table From Field From Value To Table To Field To Value
grade_grades id not null competency_evidence id not null
grade_grades itemid not null competency_evidence itemid not null
grade_grades userid not null competency_evidence userid not null
grade_outcomes scaleid not null competency_evidence scaleid not null
grade_grades finalgrade not null competency_evidence scalevalueid not null

Logging

All competency related changes should be logged in history tables.

Role capabilities and permissions

Description Capability

View hidden competencies moodle/competency:viewhiddencompetencies
Manage competencies moodle/competency:managecompetencies

Ideas for the future

  1. Due dates for course completions and outcome completions can be assigned in an individual user's learning plan.
  2. A comment can be added to a user's learning plan item when a course or outcome is manually added or removed from it.
  3. Allowing competencies to be attached to an individual user (either by user profile field or by drag and drop).
