Yes, you can assign homework using SimpleVLE. To do this, you create a task. You can upload documents to the task if you want. You can also require your students to respond to the task or homework assignment in this case.
Thats easy. Take a presentation for example. You would just create a task and explain what needs to be done in the task description. Then after the student finishes the presentation, you manually enter a grade for it.
That depends on how you assigned the test or task. If you chose to assign the test or task to the 'Entire Class', then YES the future students who weren't registered at the time will get the assignment upon adding your class.
However, if you assign the test or task to students individually, then NO future students will not get the assignment upon adding your class.
A certificate of achievement can be added to any test when the test is assigned to the class. Just select yes to
the question that asks "Do you want to make this a pass/fail test?" Then select the minimum passing grade. AFter a user
successfully completes the test they will be awarded a certificate of achievement that includes the tester's name, date,
testname, classname, and the instructor's name.
