问题 判断题

误差是观测结果、计算值或估计值与真值(或被认为是真值)之间的接近程度。( )

答案

参考答案:

解析: 了解
[试题解析] 本题考察重点是对“误差的概念”的了解。误差也被称为测量误差。按照传统误差理论的定义为:误差是指测量结果与被测量真值的差。精度是指测量误差离散行的分布程度。在测量中任何一种测量的精密程度高低都只能是相对的,皆不可能达到绝对精确,总会存在有各种原因导致的误差。所以,精度是观测结果、计算值或估计值与真值(或被认为是真值)之间的接近程度。所以,题中所叙述的是精度的概念,而不是误差的。因此,本题的叙述是不正确的。

The structure and workings of the university are ever changing. The university of the past is not like the university of the present and the university of the present will not be like the university of the future. This “adaptation” to the times is what can make some universities great or make some universities among the worst in the nation.

In the past the university was very set in their ways. They did things the way they wanted them done. They paid no attention to the rest of the society and the way the ones paying the bills wanted them done. In the past the professors would lecture endlessly to the students, which often left the students bored and with no idea what was really said to them in the lecture. This is no way to try and teach students; students need interaction with the professors that are paid to teach them. As Paulo Freire believed there needs to be communication between the students and the professors and the class should not be totally memorization. This is the way that things were done in the past.

In the present many universities have either changed or are changing the way that they run their universities. The universities now are taking on many of the modern educational beliefs in order to make changes in the teaching methods. Universities are breaking down many of the divides between majors that they offer. By breaking these barriers the universities are becoming less specialized and more diverse. This goes along with the ideas of Berry who believes that the schools are over-specialized and that the universities are now just machines that are merely meant to produce workers. In the past few years the colleges have been lowering the standards of admission, which in turn lowers the standards of all the schools below the college level. The universities are now on the right track by increasing the standards of admission into their colleges.
