Keeping track of student assessment can be an administrative problem for some practitioners. Who has done what and what they got needs to be recorded so that the practitioner has a fair idea of the progress learners are making on the programme.
Obviously this can be done on paper, on a spreadsheet or a piece of dedicated gradebook software.
You can also use the VLE as a gradebook. Used in conjunction with an assignment submission and assessment system it will allow the practitioner to know easily who has submitted a piece of work, what grade they got, revisit the feedback given and check the status of any referral work.
This data can then be exported and imported into any proprietary gradebook system the institution may have.
Another advantage of using the VLE is that the information is very easily accessible by the learner, so that they can see their grades.
