Your argument is that standardized tests are more biased than individual assessment? I find that hard to believe bordering on ridiculous. There's a great deal of evidence that standardized exams are less biased as there's a consistent standard of correct answer across the board.
With individual assessment there's far too much room for "I know what you meant" to sneak in. This has come up a lot with job interviews; if you want to interview impartialy, have a fixed bank of questions and grade answers to a rubric.
- toast0 10y agoThe argument is that an exam with free form answers is a more objective measure of knowledge than a multiple choice exam. Not an argument about bias. I think it depends on the subject matter, especially interpretation of art is hard to have one correct answer, an essay test could be graded upon support for the argument etc, where a multiple choice test is really "what did the authors of the test think the author intended?"
- RA_Fisher 10y agoAgreed. Unless we're talking about math (logic proofs), we should probably stop using the term, "objective." It's sloppy thinking.
- RA_Fisher 10y agoBecause standardized tests can be applied to such a large set, the biases of one test maker can be spread to many test takers. Contrast this with individual assessment where the biases of many test "makers" have an opportunity to cancel each other out. This is similar to the logic behind randomized assignment in randomized-control experiments. It's not that the mice are the same, it's that asymptotically their differences cancel each other out.
