东行记-火花

欢迎您--教育技术大家谈的第一位朋友!
这个链接中的内容是您一节课的内容吗？好像与您在今天的“东行记”研讨会上讲的不同。我个人感觉内容有点多，并且不完整。好像只是一些现象的罗列，但作为教案来讲，缺乏了一些基本元素。

《动物的神经调节 》这一节内容，分两节课讲授，第一节课介绍：神经元、神经元的结构、神经元的分类、神经元的功能以及反射和反射弧的原理。第二节课介绍：
1、 脑的组成
2、 高等动物的反射方式
3、 非条件反射
4、条件反射的建立（关键字：无关刺激、非条件刺激、强化、条件刺激、消退）
我设计的就是第二节课。在这个教案中我没有把它们进行细化。但是整节课的知识结构可参考图：http://www.hsshn.pudong-edu.sh.cn/zhzhguo/shenjingtiaojie/map.jpg。
我的问题是：
1、这样的设计合理吗？
2、这样的设计能否体现出信息化教学的优势？
3、怎样设计才能充分体现出信息技术的优势，来更好的完成教学目标，更充分的体现二期教改的新《生物课程标准》所倡导的教学理念：面向全体学生、提高生物科学素养、倡导探究性学习的设计指导思想。
请各位就这些问题给予意见和建议，谢谢！

张老师，我感觉您的这堂生物课把科学技术与人文、社会相结合是一大特点．使用概念图组织知识和原理，也能给学生一目了然的感受，使学生能把以前所学知识和该堂课的知识很好的联系，从而促进学生知识体系的建构．而且这堂课的教学过程的设计也很通畅，基本能实现你提出的三个方面的教学目标，符合信息化教学设计的要求，也符合教育改革提倡的学生中心，提高学生生物素养的要求！
我想问的是，基于博客的头脑风暴是在课后开展吗？课堂上只是将这一主题提出来，让学生课后完成，对吗？讨论如果在课内完成，时间该怎样安排才最恰当呢？邱少云的英雄事迹是否与非条件反射原理冲突呢？人的意志能抗拒非条件反射吗？我理解的非条件反射应该是一种天然的不为人所控制的反射．当火烧到人的皮肤的时候，肯定是不自觉的收缩，动弹．．．（因为对生物知识不太了解，可能这个问题提得不太恰当，见谅！）

谢谢zhj611的建议，我也在研究讨论如果在课内完成，时间该怎样安排才最恰当的问题。
邱少云的英雄事迹是为了说明这种防御性的非条件反射是受到人类的大脑控制的。人的意志就来源于大脑，防御性的非条件反射来源于人类的低级神经中枢——脊髓。

What is possible would never have been achieved if, in this world, people had not repeatedly reached for the impossible.

Human Growth Hormone also named hgh is a naturally occurring substance in the human body which is secreted by the pituitary, the master gland of the body located in the endocrine system.

Christianity taught that men ought to be as chaste as pagans thought honest women ought to be. The contraceptive morality teaches that women need to be as little chaste as pagans thought men need be.

Certainly it is wrong to be cruel to animals and the destruction of a whole species can be a great evil. The capacity for feelings of pleasure and pain and for the form of life of which animals are capable clearly impose duties of compassion and humanity in their case.

The chief merit of language is clearness, and we know that nothing detracts so much from this as do unfamiliar terms.

Great blog you have here. Thanks!

The history of the world is none other than the progress of the consciousness of spirit.

The difference between man and woman is like that between animals and plants. Men correspond to animals, while women correspond to plants because their development is more placid and the principle that underlies it is the rather vague unity of feeling.

A common mistake that people make when trying to design something completely foolproof was to underestimate the ingenuity of complete fools.

All the choir of heaven and furniture of earth - in a word, all those bodies which compose the mighty frame of the world - have not any subsistence without a mind.

How good one feels when one is full - how satisfied with ourselves and with the world! People who have tried it, tell me that a clear conscience makes you very happy and contented. But a full stomach does the business quite as well, and is cheaper, and more easily obtained. One feels so forgiving and generous after a substantial and well-digested meal - so noble-minded, so kindly-hearted.

The illustrious bishop of Cambrai was of more worth than his chambermaid, and there are few of us that would hesitate to pronounce, if his palace were in flames, and the life of only one of them could be preserved, which of the two ought to be preferred.

The characteristic of the hour is that the commonplace mind, knowing itself to be commonplace, has the assurance to proclaim the rights of the commonplace and to impose them wherever it will.

The advice to limit our concerns might go along with the happy belief in an invisible hand or mechanism by which a number of independent agents, each acting on their own narrow concerns, in fact maximize the social good. This mechanism is the great buttress to free markets and laissez-faire capitalism. Unfortunately, there are situations in which instead of an invisible hand there is an invisible boot, ensuring that the same agents do worse than they would under a more generous regime of concern for each other.
