心理学工作者曾就小学生延迟思维培养的问题，对在校大学生进行了两道小学数学题的测试。其一是：30800÷80=？；其二是用一直尺作出与给定角相等的角。结果回答正确的微乎其微，失误率高达85％以上，错误的原因归结为：大学生在心理上对测试题的回答持消极态度，因而在解第一道题时除数与被除数同时消“零”后，忘了在“38”后添上被除数经消“零”后仍有的一个“零”。（正确答案应为380）；解第二道题时也没有严格审查题目的给定条件——一直尺，而草率平移直尺作一条平行于终边的线得出相等角。确切地说，这完全是大学 Psychological workers have been on the problem of primary school students to delay thinking training, college students conducted two primary school mathematics test. One is: 30800 ÷ 80 =? ; The other is to use a ruler to make a given angle equal to the angle. The correct answer is negligible. The error rate is as high as 85%. The reason for the mistake is summarized as follows: The undergraduates psychologically bear the negative attitude towards the test questions, so when the first question is solved, the divisor and the dividend are eliminated, Forget forgotten after the “38” after the addition of “zero” is still a “zero.” (Correct answer should be 380). When solving the second question, there is no strict review of the given condition of the topic, ie the ruler, and the sloppy translation of the ruler gives an equal angle to a line parallel to the end. Exactly, this is completely university
