XMarks background - the portal
Staff use the portal to enter marks and to progressassessments through the Exams SystemStudents use the portal to view their marks and overall Course and Programme results
A shot from our portal showing the assessments for a given course - data from enterprise database.Contributory or non-contributory
Online assessment activities
What’s the problem?
Tutor sets up a new activity to provide formative feedback, e.g. MCQ• Details of this activity and its marks are only visible in the LMS, but students
are used to seeing all their activities and marks in the portal
Tutor sets up activity to implement a summative assessment, the details of which are already visible in the portal• The activity is visible in both the portal and the LMS, although crucial details
such as the submission deadline may differ as it has been created twice.• Marks are only visible in the LMS, until the tutor re-keys them into the portal
What’s the problem?
• Potential for confusion and inaccuracies in the presentation of
assessment and marks data to students
• Duplication of effort by staff
Two silos
Enrolment data?
Marks data?
Assessment data?

Where XMarks comes in
Enrolment data Marks data Assessment data
And it could be more complicated ..
Multiple sources of assessment
• A student record system
• A learning management system/VLE
• Web service providing on-line assessments via a particular external provider such as a text book publisher
• Web service providing a peer review tool
• etc
Background assumptions
Summative assessments
• defined when course is initially created or reviewed
• there exists a system such as a student records system that can be
identified as the parent system for all assessments
• marks need to end up in the parent system to allow overall course
result to be calculated
Institution? Department? Course?
Formative assessments
• can be created spontaneously at course or teaching group level
• there is no one source or parent for them
Use cases for student
STUDENT Views a list of all summative (contributory) assessments for a given course, including description, conflation information, submission deadline, hand-in location Views a list of all formative (non-contributory) assessments for a given course, with descriptions and deadline details Finalises and submits assessment within online assessment tool Views results and feedback within online assessment tool Views all summative (contributory) marks where available, along with any penalty point information, appeals information, etc
Views all formative (non-contributory) marks where available
Use cases for tutor
TUTOR Creates an assessment instance (e.g. a MCQ) Associates an assessment instance with a pre-existing assessment owner record [mandatory for summative optional for formative] Asserts that an assessment instance does not need to be associated with a pre-existing assessment owner record [optional for formative]
Asserts that marks are ready for processing
Implications
Summative assessments
• the key task is to match assessments created on non-originator system with the id of the originator/parent assessment record
• we always know where the “master” record is
Formative assessments
• the task may be to match existing assessment records between pairs of systems
• the task may be to create an assessment record for one system based on a record originating from another system
• we may not have a “master” record
An information model for XMarks
“Ask the audience”
