我是怎样制作生物标本的

1.在旧社会是不能搞出名堂的我从浙大生物系毕业之后,便从事生物教学,至今已有14年了,来到武冈师范也整整8年.在解放以前的日子里,一般教师常常要考虑饭碗问题,即使有些人想在制作标本方面努力,但反动的政府是不支持的,因此他们也不可能搞出名堂来,我自然也不例外. 2.新社会鼓舞了我 1949年秋,武冈解放了,六     

执教50年的回顾

1953年我从江苏师范学院(原为东吴大学,现为苏州大学)生物系毕业,时值新中国第一个五年建设计划开始的第二年。我响应祖国的号召,来到大西北,进入西北大学生物系工作。2003年是我在西北大学从事教学和科研工作的50年。回顾50年的执教历程,能取得一些业绩,主要是由于安心于西北大     

提高生物学课堂授质量的探讨

课堂讲授是教学的基本方法,高质量的课堂讲授,是提高教学效果的关键。本文提出从充分重视学生产学习主体的作用,调动学生学习的主动性;提高启发式教学质量,培养学生的思辨能力;以及吸引学生无意注意力,提高记忆效果三方面来提高课堂讲授的质量。并探讨了教师参加科学研究工作与课堂讲授效果之间的关系。     

应注意改进教学方法

三十年来,我一直从事生物学教学工作,实践使我深刻认识到,有了好的教科书,教学质量能否提高,在很大程度上是取决于教师的教学方法,而中学生物学的教学方法也已到了非改不可的时候了。从当前主客观实际出发,我想改进中学生物学教学方法应从下列三方面着手。第一,要十分重视志向和兴趣的培养志向和兴趣是学习上一种巨大的动力。培养志趣本来是我国教学方法上的一个好传统。     

充分发挥教师在中职教育中的主导地位

从事职业教育工作也有几年,我发现进入职业学校的学生不是为了就业需要,就是满足父母的需求,迫不得已在学校混日子,他们没有自己的目标,大多都有厌学情节。面对学习基础差、态度差、习惯差的学生,许多职业学校的教师在经历了短暂的几轮教学后,普遍存在着"倦怠症",备课不认真,上课不积极主动,缺乏必要的热情,没有积极性,工作懒散,得过且过,甚至个别老教师把"当一天和尚撞一天钟"作为"座右铭"。     

悼念吴襄老师

悼念吴襄老师韩济生吴襄教授是我从事生理学工作的启蒙老师。他的去世是中国生理学界的巨大损失。对我个人来说,是夺去了一位极其尊敬的老师,对我谆谆教导的长者。１９５２年９月我从上海医学院结束临床实习,到大连医学院参加生理学高级师资进修班学习,吴襄教授是进修...     

谢长泉

谢长泉同志现年50岁,共产党员,中学特级教师。1962年毕业于皖南大学生物学系。毕业至今,谢老师一直孜孜不倦地从事生物教学和生物科学实验工作。担任领导工作后,他仍然坚持上课,教书育人,他说:“当好教师是我的座右铭”。在教学中,他不断地探索教学规律,改革课     

基于创造性思维培养的中学生生物教育研究

教师在生物课堂教学活动安排上应该注重培养学生的学习兴趣,提高他们思辨与创新的能力。这篇论文结合笔者长期从事中学生物教学工作的经验和教训,着重阐述了在教学过程中激发学生创造性思维的关键性,并针对这个问题提出了一些改进教学工作的建议。

在学习、教学和科研生活中享受人生

我从小学到大学,随后四年的研究生学习,接着参加了医学院校的生物化学教学和研究工作.上世纪80年代初有幸出国进修和工作,归国后仍然一心一意从事生物化学和分子生物学的教学和科研,其间虽然也担任了一些社会工作,如多种学术团体的理事\常务理事\理事长,国家重点实验室的学术委员,国家知然科学基金委的评审委员,生物化学和分子生物学名词审定委员会委员,多种生命科学领域学术刊物编委,等等.     

Direct Reciprocity in Spatial Populations Enhances R-Reciprocity As Well As ST-Reciprocity

As is well-known, spatial reciprocity plays an important role in facilitating the emergence of cooperative traits, and the effect of direct reciprocity is also obvious for explaining the cooperation dynamics. However, how the combination of these two scenarios influences cooperation is still unclear. In the present work, we study the evolution of cooperation in 2×2 games via considering both spatial structured populations and direct reciprocity driven by the strategy with 1-memory length. Our results show that cooperation can be significantly facilitated on the whole parameter plane. For prisoner''s dilemma game, cooperation dominates the system even at strong dilemma, where maximal social payoff is still realized. In this sense, R-reciprocity forms and it is robust to the extremely strong dilemma. Interestingly, when turning to chicken game, we find that ST-reciprocity is also guaranteed, through which social average payoff and cooperation is greatly enhanced. This reciprocity mechanism is supported by mean-field analysis and different interaction topologies. Thus, our study indicates that direct reciprocity in structured populations can be regarded as a more powerful factor for the sustainability of cooperation.     

The Action Of Sulphur As A Fungicide And As An Acaricide

The conclusion arrived at by chemical methods, that the volatile agent produced when sulphur is applied to a heated surface is gaseous sulphur, has been subjected to biological tests in which the fungi Ery-siphe graminis and Sphaerotheca Humulind the gall mite Eriophyes ribis were employed.
The fungi were found not to be sufficiently sensitive to yield satisfactory and concordant results and strong support is given to the view that actual contact of the sulphur particle with the fungus is necessary before fungicidal action can occur.
It was shown that the agent present in air passed over heated sulphur and responsible for the death of the gall mite was not removed by filtration through a heated glass-wool plug, this observation being contrary to the view that the toxic agent is produced initially in solid form.
Filtration through a cooled glass-wool plug only removed part of the volatile agent and it was shown that the gall mite is affected by the traces of sulphur volatilised at ordinary temperatures.
The results of the experiments with the gall mite were in complete accord with those obtained in the previous chemical work.
At relatively large concentrations sulphur dioxide and hydrogen sulphide are without permanent effect upon the gall mite and these gases are therefore not responsible for the acaricidal action of sulphur.     

Cystic Fibrosis, A Disease of Animals As Well As Man

Cystic fibrosis, a genetically inherited disease of the exocrine glands in man, has no known counterpart in animals. The symptoms in man produced by mucous obstructing the lungs, pancreas and liver have been described. The signs, symptoms and course of an analogous disease in animals have been predicted. If an analogous disease in animals can be discovered, it is anticipated that it will make possible significant advances in the study of the normal and pathological physiology of the abnormal exocrine glands and will lead to a means of controlling the human disease.
