Impact of Computing unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Paper 1 Paper 2 Paper 3

Each paper is built from this unit’s 44 terms and is the same for everyone, so a teacher can assign “Unit 5, Paper 3” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

A school district adopts an automated system that scans student essays and assigns each one a score from 1 to 6. The model was trained on essays collected from three suburban high schools and graded by teachers at those schools. The district plans to use the scores to place students into English course levels.

Describe one clear beneficial effect of this computing innovation for the district.

Describe one harmful effect, and identify who is most likely to be harmed.

Explain how the choice of training data could introduce bias into the scores, and give a specific example of a student the system might misjudge.

Identify one data-privacy concern raised by collecting and storing student essays, and describe one specific step the district should take to address it.
