We fondly remember the Optical Mark Sheets that we used for examinations when we were students. It must have saved the examiners much effort in marking the thousands of papers.
But what about the lots of homework that our good teachers had to mark daily? Why didn't they use the Optical Mark Sheets too? Perhaps the Optical Mark Sheets were controlled items and more costly than normal A4 paper. Or perhaps the machines needed rather specialized skills to operate and were not sufficient everyone to use?
We recently started work on a Simple Teaching Assistant that could mark papers printed on normal A4 paper. You could use it with a camera or with any document scanner. First, you set up your answer key by uploading an excel file or by scanning in your model answers. Then it will start grading other pieces of homework that you scan in!
Note: Option A is the expected correct answer
for all questions in this example
Computer Vision is used to determine the shaded answers.
It is cross checked against the correct answers

Are you a teacher in Singapore who is interested in using this to help you? We will be starting our Beta testing in April 2017.
Let us know on Facebook if you are interested.

Hopefully this helps to free up more time for teaching and other more valuable tasks!
The next step would be to go completely paperless. Well, that would be even better since you will not need to even scan the papers. You would be saving the trees too!
We can help you with that too, if you like :)
