The Assessment OSID provides the means to create,
access, and take assessments. An Assessment
may represent a quiz, survey, or other evaluation that
includes assessment Items. The OSID defines
methods to describe the flow of control and the
relationships among the objects. Assessment Items
are extensible objects to capture various types of
questions, such as a multiple choice or asset submission.
The Assessment service can br broken down into several
distinct services:
- Assessment Taking
- Assessment and Item authoring
- Accessing and managing banks of assessments and
items
Each of these service areas are covered by different
session and object interfaces. The object interfaces
describe both the structure of the assessment and follow
an assessment management workflow. They are:
-
Item : a question and answer pair
-
Response: a response to an
Item question
-
Assessment : a set of Items
-
AssessmentPart: A grouped set of
Items for fancier assessment sequencing
-
AssessmentOffering: An
Assessment available for taking
-
AssessmentTaken: An
AssessmentOffering that has been completed or
in progress
The AssessmentSession is used to take
an assessment and review the results. It captures various
ways an assessment can be taken which may include time
constraints, the ability to suspend and resume,
availability of an answer key, or access to a score or
other evaluation. Care should be taken to understand the
various interoperability issues in using this interface.
An AssessmentSession may be created
using an AssessmentOffered or
AssessmentTaken Id. If instantiated
with an AssessmentOffered Id,
an AssessmentTaken is implicitly
created and further references to its state should be
performed using the AssessmentTaken
Id.
An AssessmentSession is a mapping of an
AssessmentOffered to an Agent
at a point in time. The resulting
AssessmentTaken is an identifier representing this
relationship.
On the authoring side, Items map to
Assessments. An Item may appear in
more than one Assessment. Item banks may be
used to catalog sets of Items and/or sets of
Assessments.
