选择题作为客观性试题的一种类型,它具有知识覆盖面广、干扰性强、能考查学生的多种能力、评分客观准确等优点。因而,选择题被广泛地应用在各种考试之中。在众多的物理选择题中,有一类具有三个答案的多选题,由于各种因素造成三个同时符合题意的答案,使得这种题目有很强的迷惑性和干扰性,在考试中,这种类型的选择题往往得分率比较低,学生解答时常会出现漏解或错解现象。要完整准确地解答这类选择题,除了要熟练地掌握物理的基本概念和规律外,还应结合这类选择题的特点,特别是针对造成多解的各种因素,要仔细分析、灵活应变、严密推理、全面考察、拓展
Multiple-choice questions are a type of objective questions. They have the advantages of wide coverage of knowledge, strong interference, ability to examine students’ multiple abilities, and objective and accurate scoring. Therefore, multiple-choice questions are widely used in various examinations. Among the many physical choice questions, there is one type of multi-choice question with three answers. Due to various factors, three simultaneous answers to the meaning of the question are made, making this kind of question very confusing and intrusive. This type of multiple-choice questions tends to have lower scores, and students often have missing or misinterpreted answers. To fully and accurately answer such multiple-choice questions, in addition to mastering the basic concepts and laws of physics, we should also combine the characteristics of such multiple-choice questions, especially for the various factors that cause multiple solutions, to be carefully analyzed and flexible. , rigorous reasoning, comprehensive investigation, expansion
