多项选择题是学业考试中常见的题型。其中多选一作答方式是多项选择题中最简单的答题方式。但是多选一方式容易出现被试猜测答案的行为,即使被试只是掌握部分知识或者根本不知道答案时也有选对答案的可能。而作为评分者对这种多选一的答案又无法判断被试究竟存在多大程度的猜测。在可能用于多项选择题的作答方式中,理论上确信度作答方式是多项选择题的最佳作答方式。为了发现确信度作答方式在实际应用中存在的问题,笔者于2007年12月对广东省某市的500余名高中生进行了关于确信度作答方式的实证研究,并对采集的数据进行了详细分析与探讨。
Multiple choice questions are common questions in academic exams. One of the multiple choice of answer is the easiest way to answer multiple choice questions. However, it is easy for candidates to guess the answer in one way or another, even if the subjects only have some knowledge or do not know the answer at all. And as a scorer for this multiple choice of one answer and can not determine how much the participants guess the extent they exist. Among the possible ways of answering multiple choice questions, the way of answering questions in theory is the best way to answer multiple choice questions. In order to find out the practical problems of the way of confirming the answer, the author conducted an empirical study on the way of confirming the answer in more than 500 high school students in a city of Guangdong Province in December 2007, and conducted detailed analysis on the collected data Analysis and discussion.
