大学生の２４％が「平均」の意味を正しく理解していない（You do not understand properly the meaning of the "average" 24% of the students）

大学生の２４％が「平均」の意味を正しく理解していないなど、基礎的な数学力、論理力に大きな課題があることが、日本数学会が実施した初の「大学生数学基本調査」で明らかになった。
　理系学生やセンター入試で数学を受験した大学生も多数含まれており、入試のあり方も問われそうだ。
　調査は昨年４月から７月にかけ、国公立大から私立大まで４８大学で実施。主に入学直後の学生５９３４人が協力した。調査では小中学校で学ぶ内容を中心に、論理的な文章の読解や記述力、基本的な作図力を問う５問が出題された。
　その結果、全問正答した学生は、わずか１・２％だった。「偶数と奇数を足すとなぜ奇数になるか」を論理的に説明させる中３レベルの問題の正答率は１９・１％。小６で学ぶ「平均」についても、求め方は分かるが、「平均より身長が高い生徒と低い生徒は同じ数いる」などの正誤については誤答が目立ち、中堅私大では半数が誤答だった。
問題は、 「１００人の平均身長が１６３．５センチ」の場合、（１）１６３．５センチより高い人と低い人はそれぞれ５０人ずついる（２）全員の身長を足すと１万 ６３５０センチになる（３）１０センチごとに区分けすると１６０センチ以上１７０センチ未満の人が最も多い――のそれぞれが正しいかどうかを聞いた。正解 は（１）は×、（２）は○、（３）は×だが、全問正答率は７６％にとどまった。
　秋入学云々を議論する前に、初等教育を見直し改善していくことが重要な気がしますね。こんな学生が全入時代で大学に入っていくわけですから大学の質は低下せざるをえないでしょうね。外的な入学月を変えようが本質的に何も変わらないでしょうね。

Such as those that do not properly understand the meaning of "average" 24% of college students, that there is a major challenge mathematical skill, to force a logical basic, obvious in the "Basic Survey Math students," the first was conducted by the Mathematical Society of Japan became.Includes many college students who choose to take the entrance examination center in mathematics and science students, but also likely to be asked the way for the entrance examination.Subjected to investigation from April to July last year, conducted at the University of up to 48 private universities from Kokkoritsudai. People immediately after the 5934 student enrollment was primarily cooperation. The survey is to learn by heart the contents of elementary and junior high schools, reading and writing skills questions ask five of logical sentences, the power has been drawing basic questions.As a result, students who correct answer all the questions, it was only 1.2%. Percentage of questions answered correctly three levels of 19.1% in the cell is a logical explanation "why and how an odd plus the even and odd." For "average" learn, who is seen in six small request, errata for "students and students of the lower height is higher than the average have the same number," such as the wrong answer is noticeable, depending on the medium-sized half was wrong answers was.
The problem is, in the case of (1) and low human person is higher than the 163.5 centimeter 16350 centimeter and the height of all plus (2) that each one by 50 "100 163.5 centimeters in average height of a person" asked whether each of the correct - the most human of less than 160 cm and 170 cm or more in each division (3) become 10 centimeter. The correct answer is (1) ×, (2) are ○, (3) is however ×, the percentage of correct answers all the questions was only 76%.
Before discussing our fall enrollment clouds, I feel it is important to continue to improve the primary education review. Quality of the university I would have no choice but to decline from the university is not going into this New Era of Open Admissions students. I will not change anything, but essentially trying to change the external entrance Mon.
