In trying to save paper at our school, a colleague and I came across this site called Classmarker.com. We've piloted this in both of our classes and are quickly moving towards almost non-paper summative assessments. They have just upgraded many new features on the site, and here is a list of some new things they have added.
# You can now add multiple choice, multiple response, free text, true/false, punctuation and essay questions all in the same test.
# All your questions from all your test are now exported into your questions banks to easily add to any of your tests if you like.
# All your tests are now grouped together, ordered by Category then alphabetical test name (no separation of test types anymore because they are all universal now)
# We have removed flash for serving the tests. All tests are now given in plain html for much better accessibility.
# All results are saved as the test is taken, so if a learner clicks away or closes their browser - they can log straight back in within 20 minutes and ClassMarker will allow them to resume the test. If you have the test set to 'save results and finish later', they can come back anytime to finish the test.
Obvious downfalls that we've come across. We have a small computer lab and one of our classes is extremely large and cannot fit in the lab for one testing session. We have yet to figure out what to do instead of allowing students to take the test on their own time or breaking the class up into different sessions.
I hope this helps someone. I'll followup with more as we continue to use Classmarker.
