课文摘录：
活字印刷术的发明
我国在隋唐时期发明了雕版印刷术，促进了文化的发展。辽、宋、西夏、金时期，刻书很盛行。雕版印刷技术进一步发展。但雕版印刷刻版费工费时，而且刻好的版只能印制一种书籍。在多年探索的基础上，宋代的印刷技术有了新的突破，这就是活字印刷术的问世。
活字印刷术是由北宋时期的匠人毕异发明的。他用胶泥刻字，然后用火烧制，使字模变硬。制版时，在一块四周有框的铁板上撒上松脂、石蜡和纸灰等，将烧制好的字模在铁板上排成版，用火将铁板中的松脂熔化，将字版压平，这样就可以印书了。印完之后，再将松脂熔化，泥字拆开，然后又可以再次排版。此后，能工巧匠们又发明了木活字。到了元代，著名的科学家王祯在《农书》中对木活字技术做了系统的总结并有所创新，发明了转轮排字法。元朝中期，出现了铜活字印刷。

要求：根据《义务教育历史课程标准（2011年版）》要求和课文内容，设计出相关的教学过程，包括教学环节、教师活动和学生活动，并说明设计意图。

材料：
关于新航路开辟，《普通高中历史课程标准（实验）》要求：“概述迪亚士、哥伦布开辟新航路的史实，认识地理大发现对世界市场形成的意义。”某版本历史教科书“开辟新航路”一课包括三个子目：“东方的诱惑”“新航路的开辟”和“走向会合的世界”。某教师在讲完新航路开辟的历史背景后，针对第二子目，为调动学生参与活动的积极性，围绕《新航路开辟示意图》开展了两个教学活动：（1）让学生用不同颜色的彩笔在地图上按时间顺序描出四条航线；（2）分组讨论哪一条航线最容易到达东方。为此，学生对航海路线、造船技术、洋流、季风等展开了热烈讨论，直至下课，讨论活动仍未结束。
问题：
（1）这位教师的教学有哪些可取之处（4分）？存在哪些问题？（6分）
（2）请你对这位教师提出改进的建议。（6分）

怎样培养后进生的积极兴趣?

材料：
在古代中国的政治制度的相关内容讲授完毕后，王老师组织学生利用一节课的时间对相关学习内容进行讨论。上课伊始，王老师以中央集权制不断强化为线索，将“中国古代中央集权制利大还是弊大”作为讨论题目，将学生分成两组，选择其中一个观点展开讨论，陈述各自的理由。一堂45钟的讨论课，学生们可谓唇枪舌剑，不仅列举课上学到的知识，还将自己的心得体会、课下搜集的资料用到讨论中，学习气氛热烈。王老师看到这样的场景，感到十分欣慰。
问题：
结合材料内容，分析该教师组织的讨论课的作用和注意事项是什么。（16分）

语言素材：
Good teacher
To be a good teacher，you need some of the gifts of a good actor；you must be able to hold the attention and interest of your audience；you must be a clear speaker，with a good，strong，pleasing voice which is fully under your control；and you must be able to act what you are teaching，in order to make its meaning clear.
Watch a good teacher，and you will see that he does not sit still before his class: he stands the whole time he is teaching；he walks about，using his arms，hands and fingers to help him in his explanations，and his face to express feelings. Listen to him，and you will hear the loudness，the quality（音色）and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn't mean that he will indeed be able to act well on the stage，for there are very important differences between the teacher's work and the actor's.The actor has to speak words which he has learnt by heart；he has to repeat exactly the same words each time he plays a certain part，even his movements and the ways in which he uses his voice are usually fixed beforehand（预先）.What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don't understand something, they say s0. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
I have known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
