近年来中考中出现了一类“是否正确”式辨析型物理考题,这类考题一般要求判断试题中的某个或某些问题(如解题过程、实验方案、实验结论、解决措施等)是否正确、是否成立、是否存在,由学生自己作出判断.如若认为正确、成功、存在,需进一步加以分析、解答、论证;若认为不正确、不成立、不存在,需要说明其不正确、不成立、不存在的理由,或者给出正确的解答.这种命题综合性强,由于存在着结论的双重性与不确定性,增加了解题难度,解答时要通盘考虑,全面分析,巧妙运用所学知识加以灵活处理,学生常感到左右为难,不能顺利解决.此类型题能体现学生的质疑能力,培养学生严谨的治学态度和尊重科学的精神,也能较好地考查学生分析问题和解决问题的能力,颇为新颖独特.
In recent years, a type of “correctness” analytical test has appeared in the senior high school entrance examination. Such examination questions generally require judgment of one or some of the questions (such as solving process, experimental plan, experimental conclusion, solution measures, etc.) ) Is correct, is established, exists, the students make their own judgments .If it is correct, successful, there is need to be further analyzed, answered, argumentation; if not correct, not established, there is no need to explain its incorrect, not established , There is no reason, or give the correct answer.This proposition comprehensive, due to the existence of the duality and uncertainty of the conclusion, increasing the difficulty of solving the problem, to consider the overall consideration, a comprehensive analysis, clever use of Learn to be flexible, students often feel dilemma, can not be successfully resolved.This type of problem can reflect the ability of students to question, cultivate students rigorous attitude toward learning and respect for the spirit of science, but also to better examine the students to analyze and solve problems The ability, quite new and unique.
