选择题具有概念性强,迷惑性大,覆盖面广,能较全面考查能力等特点。我市从1985年在中学物理升学卷中采用了选择题以来,经过十年的不断改进,发生了较大的变化。主要表现在:题量逐渐增加;覆盖面明显加大;试题的灵活性和综合性有所提高;难度比例趋于合理,这种变化增加了同学们解答选择题的难度,致使得分率有下降趋势,因此对选择题的研究是一个值得重视的问题。
The multiple-choice questions have the characteristics of strong conceptual, confusing, wide coverage, and ability to conduct comprehensive examinations. Since the city adopted the multiple-choice questions in the middle school physics study volume in 1985, after a decade of continuous improvement, great changes have taken place. Mainly manifested in: the amount of questions gradually increased; coverage significantly increased; the flexibility and comprehensiveness of the test questions have been improved; the difficulty ratio tends to be reasonable, this change increases the difficulty of the students to answer multiple choice questions, resulting in a downward trend in the score Therefore, the study of multiple-choice questions is a problem worthy of attention.
