After shaking the east coast of Honshu, Japan on March 11, the earthquake has caused more than 10, 000 deaths and 17, 000 people missing. In downtown of Tokyo, buildings shook and frightened citizen blocked out all the streets and roads. The tsunami（飓风）afterwards, which caused more deaths and injury, made Japanese people unable to cheer up. “Now that our neighbors are in trouble,” the Foreign Ministry spokesman said, “we are in our turn to give a hand. Our rescue team has already got there in time to help.” The terrible earthquake also caused a big fire breaking out at the Fukushima nuclear power plant（福岛核电站）, leading to a radiation leaking（泄漏）.

50 nuclear workers, facing radiation and fire, became the only people remaining at the Fukushima nuclear power plant on Tuesday — and perhaps Japan’s last chance of preventing a broader nuclear danger. They have volunteered to put seawater on dangerous nuclear fuel（核燃料）to cool it down, to prevent thousands of tons of radioactive dust high into the air. Some scientists suggest that the leaking is harmful to human being and may influence human body through rain or snow from the sky in the future.

阅读下列材料，回答问题。下面是张老师"传统工业区"一课的教学设计：教学设计思路：复习工业区位选择原理，分析鲁尔工业区区位特点、衰落原因、综合整治措施→得出分析传统工业区的方法→呈现辽中南工业区案例→分析辽中南工业区区位、特点及发展滞后原因、整治措施→辽中南案例的总结评价。分析传统工业区案例--鲁尔工业区之后，再呈现类似案例--东北老工业基地的资源材料。将学生分成四组，设置解决主题的四个不同核心问题，让学生利用鲁尔区案例得出的分析传统工业区的方法，展开对辽中南工业区的分析和讨论。请几位学生代表发表自己的看法，教师及时评价、分析、讲解、拓展，最后归纳案例，指出分析案例要从时间（过去、现在、将来）和空间（不同地区）两个视角来认识、理解、应用地理原理，同时指出不能仅由一个案例来理解原理，以免"以偏概全"，因为案例尽管典型但还是有局限性的。

上述材料中，该教师主要采用了哪种地理教学方法？并对此教学方法进行解释。

相对误差是（）。

A.测量值与真值之差

B.测量值与真值之比

C.两次测量的相对误差相等

D.是绝对误差与真值之比

E.不能与绝对误差同用
