A better brute-force algorithm places a single queen on each row, leading to only 8 8 = 2 24 = 16,777,216 blind placements. It is possible to do much better than this. One algorithm solves the eight rooks puzzle by generating the permutations of the numbers 1 through 8 (of which there are 8! = 40,320), and uses the elements of each permutation ...

Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants , observer bias , confirmation bias , and other ...
Free response questions typically require little work for instructors to write, but can be difficult to grade consistently as they require subjective judgments. Free response tests are a relatively effective test of higher-level reasoning, as the format requires test-takers to provide more of their reasoning in the answer than multiple choice ...

[1] Closed-ended questions are sometimes phrased as a statement that requires a response. A closed-ended question contrasts with an open-ended question, which cannot easily be answered with specific ...
