The terms Multiple True/False and Best Answer deserve wider applicability than at present when discussing multiple choice questions (MCQs). They describe the truthfulness of the choices and distinguish between the question types. The choice which matches the key in a MCQ is best called the correct answer. Multiple True/False questions contain either true (accepted) or false (unaccepted) ideas in the correct answers while in the Best Answer type, all choices are true. Using a complex recording procedure to indicate the selections already made, as in the K-type MCQ, does not assess any additional abilities. Candidates answering Multiple True/False MCQs should be asked to respond to each choice as either true or false. This helps to discriminate between those who can detect the falsity of a false choice from those who cannot. When dealing with guessing, examiners need to be cognizant of issues such as blind guessing and informed guessing, proclivity for risk-taking, extension of the marking range and probabilities according to the binomial distribution.
在讨论多项选择题(MCQ)时,“多重是非题”和“最佳答案题”这两个术语应比目前具有更广泛的适用性。它们描述了选项的真实性,并区分了问题类型。在MCQ中与答案匹配的选项最好称为正确答案。多重是非题的正确答案中包含真(可接受)或假(不可接受)的观点,而在最佳答案题中,所有选项都是真的。像K型MCQ那样使用复杂的记录程序来表明已做出的选择,并不能评估任何额外的能力。应要求回答多重是非题的考生对每个选项判断其真假。这有助于区分能够识别错误选项的考生和不能识别的考生。在处理猜测问题时,考官需要认识到诸如盲目猜测和有根据猜测、冒险倾向、评分范围的扩展以及根据二项分布的概率等问题。
