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 .
