A. 瓦特发明了....

瓦特在同年设计了一种带有分离冷凝器的蒸汽机。按照设计，冷凝器与汽缸之间有一个调节阀门相连，使他们既能连通又能分开。这样，既能把做工后的蒸汽引入汽缸外的冷凝器，又可以使汽缸内产生同样的真空，避免了汽缸在一冷一热过程中热量的消耗，据瓦特理论计算，这种新的蒸汽机的热效率将是纽可门蒸汽机的三倍。从理论上说，瓦特的这种带有分离器冷凝器的蒸汽机显然优于纽可门蒸汽机，但是，要把理论上的东西变为实际上的东西，把图纸上的蒸汽机变为实在的蒸汽机，还要走很长的路。瓦特辛辛苦苦造出了几台蒸汽机，但效果反而不如纽可门蒸汽机，甚至四处漏气，无法开动。尽管耗资巨大的试验使他债台高筑，但他没有在困难面前怯步，继续进行试验。当布莱克知道瓦特的奋斗目标和困难处境时，他把瓦特介绍给了自己一个十分富有的朋友--化工技师罗巴克。当时罗巴克是一个十分富有的企业家，他在苏格兰的卡隆开办了第一座规模较大的炼铁厂。虽然当时罗巴克已近50岁，但对科学技术的新发明仍然倾注着极大的热情。他对当时只有三十来岁的瓦特的新装置很是赞许，当即与瓦特签订合同，赞助瓦特进行新式蒸汽机的试制

B. 瓦特发明家的故事

瓦特出生于英国的格林诺克，由于家境贫穷没机会上学，先是到一家钟表店当学徒，后又到格拉斯哥大学去当仪器修理工，瓦特聪明好学，他常抽空旁听教授们讲课，再加上他整日亲手摆弄那些仪器，学识也就积累的不浅了。

1764年，格拉斯哥大学收到一台要求修理的纽可门蒸汽机，任务交给了瓦特。瓦特将它修好后，看看他工作那么吃力，就象一个老人在喘气，颠颠颤颤地负重行走，觉得实在应该将它改进一下。

他注意到毛病主要是缸体随着蒸汽每次热了又冷，冷了又热，白白浪费了许多热量。能不能让它一直保持不冷而活塞又照常工作呢？于是他自己出钱租了一个地窖，收集了几台报废的蒸汽机，决心要造出一台新式机器来。

从此，瓦特整日摆弄这些机器，两年后，总算弄出个新机样子。可是点火一试，那汽缸到处漏气，瓦特想尽办法，用毡子包，用油布裹，几个月过去了，还是治不了这个毛病。

一天他又趴到汽缸前观察漏气的原因，不小心一股热气冲出，他急忙躲闪，右肩上已是红肿一片，就像被一把热刀削过一样，辣辣地疼起来，弄得他心烦意乱。他真有些灰心了，这时，是他的妻子给了他勇气，妻子用激将法又激起了继续研究下去的雄心。

他又回到地下实验室，将过去的资料重新翻阅一番，打起精神又干了起来，干累了就守着炉子烧一壶水喝茶。一天，他一边喝茶，一边看着那一动一动的壶盖。他看看炉子上的壶又看看手中的杯子，突然灵感来了：茶水要凉，倒在杯里；蒸汽要冷，何不也把它从汽缸里也“倒”出来呢？

这样想着，瓦特立即设计了一个和汽缸分开的冷凝器，这下热效率提高了三倍，用的煤只有原来的四分之一。这关键的地方一突破，瓦特顿然觉得前程光明。他又到大学里向布莱克教授请教了一些理论问题，教授又介绍他认识了发明镗床的威尔金技师，这位技师立即用镗炮筒的方法制了汽缸和活塞，解决了那个最头疼的漏气问题。

1784年，瓦特的蒸汽机已装上曲轴、飞轮，活塞可以靠从两边进来的蒸汽连续推动，再不用人力去调节活门，世界上第一台真正的蒸汽机诞生了。

C. 瓦特简介

瓦特是指詹姆斯·瓦特，出生于1736年1月19日，是英国发明家，他开辟了人类利用能源新时代，使人类进入“蒸汽时代”。后人为了纪念这位伟大的发明家，把功率的单位定为“瓦特”（简称“瓦”，符号W）。

1784年，瓦特对联协式蒸汽机进行了改进，增加了一种自动调节蒸汽机速率的装置，使它能适用于各种机械的运动。从此之后，纺织业、采矿业、冶金业、造纸业等工业部门，都先后采用蒸汽机做为动力。

瓦特蒸汽机发明的重要性是难以估量的，它被广泛地应用在工厂成为几乎所有机器的动力，改变了人们的工作生产方式，极大地推动了技术进步并拉开了工业革命的序幕。

它使得工厂的选址不必再依赖于煤矿而可以建立在更经济更有效的地方，也不必依赖于水能从而能常年地运转，这进一步促进了规模化经济的发展，大大提高了生产率的同时也使得商业投资更有效率。

蒸汽机为一系列精密加工的革新提供了可能，更高的工艺保证各种机器包括蒸汽机本身的性能提高。经过不断的努力，引入更高气压的蒸汽，蒸汽火车蒸汽轮船便很快相继问世。

D. 瓦特发动机的两个缺点

缺点是缸体热负荷能力不如铸铁发动机，升功率挖掘潜力也不如铸铁，铝的耐腐蚀性也不如铁，而且价格要比铸铁的高出不少。

E. 瓦特为什么被称为第一代现代技术专家

瓦特出生于1736年1月19日。他的父亲是一名造船工匠，并且经营各种海运，有一个修理厂。其母是一位有着丰富知识的家庭妇女。瓦特生来体弱，性格孤僻，经常请假不能正常上学，因此，功课也不是很好。但他的求知欲非常强烈，特别喜欢几何学。由于身体不好，瓦特中学没有毕业，就退学回到家中自学。瓦特后到父亲的工厂里学习技术，操作各种工具。经过几年的磨炼，他先后学会了木工、金属冶炼和加工、机械制造、仪器修理等多种工艺，为后来的发明打下了坚实的基础。

1753年，瓦特的父亲经商失败，接着母亲去世，家中一贫如洗。17岁的瓦特被迫外出谋生，到格拉斯哥一家钟表店当学徒。两年后又到达伦敦，在著名机械师摩尔根门下为徒。1756年，他回到了苏格兰，瓦特本想自己开业制造器械，但是由于他的学徒年限不够，不符合市政当局的要求，只得经朋友介绍，在市政当局管辖的格拉斯哥大学当了一名修理教学仪器的工人。不久，一位商人向格拉斯哥大学捐赠了一大批天文仪器，但很破旧，不能正常运转。瓦特主动承担了修理这些仪器的任务，并很快修复了。一位教授由衷地称赞道：瓦特是一个机械知识丰富，非常机敏和具有过人才能的年轻人。

1763年，又有人给格拉斯哥大学送来了一台损坏了的蒸汽机模型。瓦特被指派为全权负责修理，让这台机器发动起来，供学生做实验用。谁也没有想到这竟成为瓦特在人类历史上留下伟大功绩的开端。

蒸汽机是一种利用水蒸气把热能转变成机械能的动力装置。人类对蒸气的认识和利用，经历了一段较长的历史。英国君主立宪制确立后，英国的工业迅速发展，珍妮纺纱机和水力纺纱机等机器的使用日益广泛，但动力问题却成为扩大机器生产的“瓶颈”。1705年，英国铁匠钮可门制成了可用于矿井抽水的“钮可门蒸汽机”。但因存在着燃料消耗过多，只能往复直线运动，且温度无法控制的缺点，未能在其他生产部门广泛采用。

瓦特主持修理的正是一台“钮可门蒸汽机”，他接受这一任务后很快就把这台钮可门发动机模型修好了。但他对此并不满足，通过这次修理，瓦特对蒸汽机的结构、性能和存在的问题有了更多的了解，并且产生了浓厚的兴趣，像着了迷一样。他观察到钮可门发动机的活塞从根本上说是用机械的力量取代了人的双手，但是一分钟只能往返10次，工作效率极低。他决心改进蒸汽机的设计。

瓦特开始学习蒸汽机的原理，根据发动机的原理来考虑问题。他又研究了蒸气的性质，从蒸气和燃料的消耗等具体问题开始研究，然后扩大到热的移动和发动机的关系等抽象问题上。他进行了多次实验，但仍没有想出一个改良“钮可门蒸汽机”效率的具体办法。

在一个晴朗的星期天下午，瓦特正在郊外散步，但他的脑海里仍然在思考着蒸汽机问题。突然他脑中闪出一个念头：加装一个蒸气冷凝器，就可以弥补蒸气在汽缸里冷却凝聚而过多浪费热量的重大缺陷。他马上辞去了在格拉斯哥大学的工作，全身心地投入了试制样机的工作。在租借的地下室里，瓦特和他的助手经过反复试验，终于在1768年制成有分离冷凝器的单动式蒸汽机，第二年获得专利申请。瓦特的蒸汽机比钮可门的蒸汽机有更显著的优点：它的安全性更可靠，运动更迅速，燃料耗费也减少了75％。大家都夸奖瓦特的发明。

“不!它只是单动式的。我还要制造联动式的，让它更圆满地运转!”瓦特并不满足于自己的成就。

1774年，瓦特因妻子去世，从苏格兰迁居伯明翰。在制造商波尔顿的支持下，继续进行蒸汽机的制作和改进工作。1781年，瓦特采用了行星齿轮机构，使蒸汽机从往返运动变为旋转运动。1782年，瓦特制造了更为完善的联动式蒸汽机，功效提高4倍。1784年他又发明了平行连杆机构，使蒸汽机具有更广泛的应用性。一年后，英国出现了第一座采用蒸汽机作为动力的纺纱厂。1788年瓦特发明了离心调速器和节气阀。1790年，制成汽缸示动器，最终完成了对蒸汽机的整个发明过程。从此，性能优越的瓦特蒸汽机完全取代了老式钮可门发动机。

从技术角度而言，瓦特蒸汽机与钮可门发动机有着质的差别，钮可门发动机的活塞运动一部分靠蒸气推动，另一部分靠外界的大气压力推动。而瓦特蒸汽机采用密封气缸，活塞运动完全靠蒸气的推力，所以才堪称世界上第一台蒸汽机。此外，把离心调节器用于蒸汽机，创造了动力单位——马力，也是瓦特的功劳，离心调节器是一种通过过程本身的变化来控制过程的装置。自动化的兴起虽然是20世纪以后的事，但它起始于瓦特。调节器这个词，通过希腊语，为我们提供了一个现代语——控制论。

从研究方法的角度来看，瓦特没有进入当时手工艺人的行列，也未受过高等教育。但他找到了观察认识和研究探索蒸汽机的新道路，就是从科学和实用两个方面去分析发动机是如何工作的。这是现代技术专家所特有的研究方法，因此我们把瓦特称之为第一位现代技术专家一点也不过分。

F. 瓦特交易所停止提币，我的资产怎么办

然后就是网上注册一个数字钱包。全部转过去。然后一直放着就可以了。
至于你说的那个网站我就不知道了，如果还能登陆还有戏。如果不能登陆的话，那就黄了。这玩意儿也不受到我们的法律的保护，大概率只有自己认了。

G. 你的教鞭下有瓦特，你的冷眼里有牛顿，你的讥笑里有爱迪生

从师德方面来说，就是对学生不能过多的进行批评，在你的讥笑与嘲讽中学生的创新会被扼杀，对学生的评价要客观，多方面，比如爱学生更应该爱学困生，后进生。

世界上的爱各种各样，班主任对学生的评价是一种爱。班主任与学生朝夕相处，深入细致地了解学生，真心实意地关心学生，充分尊重、信任学生，严格地要求学生等都是对学生的爱。教育心理学家认为，班主任的爱不同于父母对子女的天然之爱，不仅是个人之间的一种态度，它蕴含更多的社会内容，具有广泛的社会意义。班主任对学生的态度常常反映学生所在集体，甚至是社会对他的某种评价。因此，学生往往把班主任对自己的关怀、爱护、信任、评价同自己在集体中的地位和人格价值联系在一起。班主任的这种情感实际上就转化为一种社会环境因素在每个学生心目中不同寻常的心理份量。由此可见，班主任的爱对教育好学生是多么重要啊！
教育不能没有爱，就像池塘不能没有水一样。前苏联教育家苏霍姆林斯基则把教师热爱学生作为“教育的奥秘”，他的座右铭是“把整个心灵献给孩子们。”
有经验的班主任都会有这样的体会，当学生意识到班主任是真心爱护他关心他，为他操心时，无论你是耐心的帮助，还是严肃的批语甚至是必要的斥责，学生都会乐意接受。这就是所谓“亲其师，信其道”，
相反，如果班主任没有取得学生的信任，那么即使你教育目标正确，教育方法科学，教育也无法达到期望的结果。因为在教育过程中，学生既是老师作用的对象，又随时显示一种“反作用”，这种反作用表现在：班主任的教导和要求，都要经过他们情感的过滤或催化。如果师生没有达成信任，学生面对班主任教师的教导就无动于衷，严惩的还会产生抵触情绪和对抗行为。这种感情上的相悖，怎能教育好学生？我一般在班会上评价学生，有时在下课时当着部分学生的面评价学生。每个学期结束填写素质报告单时针对学生情况写出批语。教育学生要遵循因材施教的原则，内向和缺乏自信的学生要给予鼓励，对自己要求不严的学生要严肃批评.

A. Watt invented....

Watt designed a steam engine with a separate condenser in the same year. According to the design, a regulating valve is connected between the condenser and the cylinder, allowing them to be connected and separated. In this way, the steam after work can be introduced into the condenser outside the cylinder, and the same vacuum can be generated in the cylinder, avoiding the consumption of heat during the cooling and heating process of the cylinder. According to Watt's theoretical calculation, this new steam engine The thermal efficiency will be three times that of the Newcomen steam engine. Theoretically speaking, Watt's steam engine with a separator and condenser is obviously better than the Newcomen steam engine. However, it is necessary to turn theoretical things into practical things and turn the steam engine on the drawing into a real steam engine. , there is still a long way to go. Watt worked hard to build several steam engines, but the effect was not as good as the Newcomen steam engine, and even air leaked everywhere and could not be started. Although the costly experiments left him heavily in debt, he did not shy away from the difficulties and continued the experiments. When Black learned about Watt's goal and difficult situation, he introduced Watt to a very wealthy friend of his - chemical technician Roebuck. Roebuck was a very wealthy entrepreneur at that time. He opened the first large-scale ironworks in Caron, Scotland. Although Roebuck was nearly 50 years old at the time, he still had great enthusiasm for new inventions in science and technology. He was very impressed with the new device of Watt, who was only in his thirties at the time, and immediately signed a contract with Watt to sponsor Watt's trial production of a new steam engine

B. The story of Watt's inventor

Watt was born in Greenock, England. Due to his poor family, he had no chance to go to school. He first worked as an apprentice in a watch shop, and then worked as an instrument repairman at the University of Glasgow. Watt was smart and studious, and he often found time to listen to professors' lectures. He played with the instruments with his own hands all day long, and accumulated a lot of knowledge.

In 1764, the University of Glasgow received a Newcomen steam engine that required repair, and the task was assigned to Watt. After Watt repaired it, he saw how hard he was working, like an old man panting and trembling while walking with a heavy load. He felt that it should be improved.

He noticed that the main problem was that the cylinder heated up and then cooled down, and cooled down and heated up again with the steam, which wasted a lot of heat. Can it be kept cold and the piston work as usual? So he rented a cellar with his own money, collected several scrapped steam engines, and determined to build a new machine.

From then on, Watt played with these machines all day long. After two years, he finally came up with a new machine. But after trying to ignite it, the cylinder leaked air everywhere. Watt tried his best to wrap it with felt and oilcloth. Several months later, he still couldn't cure the problem.

One day he lay down in front of the cylinder to observe the cause of the air leakage. Unexpectedly, a burst of hot air rushed out. He hurriedly dodged. His right shoulder was already red and swollen, as if he had been cut by a hot knife. It was the same, a sharp pain, which made him upset. He really has someHe was discouraged. At this time, it was his wife who gave him the courage, and his wife used provocation to arouse his ambition to continue his research.

He returned to the underground laboratory, read through the past materials again, cheered up and started working again. When he was tired, he would stand by the stove and boil a pot of water for tea. One day, while drinking tea, he looked at the moving lid. He looked at the kettle on the stove and then at the cup in his hand, and suddenly an inspiration came to him: the tea needs to be cold, so pour it into the cup; the steam needs to be cold, why not "pour" it out of the cylinder too?

With this in mind, Watt immediately designed a condenser that was separate from the cylinder. This tripled the thermal efficiency and used only a quarter of the original coal. Once this key point was broken through, Watt suddenly felt that his future was bright. He went to the university to ask Professor Black for some theoretical questions, and the professor introduced him to technician Wilkin who invented the boring machine. The technician immediately used the method of boring the barrel to make the cylinder and piston, solving the most troublesome problem. Air leakage problem.

In 1784, Watt's steam engine was equipped with a crankshaft and flywheel. The piston could be continuously pushed by steam coming in from both sides. There was no need for manpower to adjust the valve. The world's first real steam engine was born.

C. Watt Introduction

Watt refers to James Watt, born on January 19, 1736. He is a British inventor. He opened up a new era of energy utilization for mankind and enabled mankind to Entering the "Age of Steam". In order to commemorate this great inventor, later generations set the unit of power as "Watt" (abbreviated as "Watt", symbol W).

In 1784, Watt improved the Union steam engine and added a device that automatically adjusted the speed of the steam engine, making it suitable for various mechanical movements. Since then, the textile industry, mining industry, metallurgy industry, paper industry and other industrial sectors have successively adopted steam engines as power.

(3) Extended reading of Watt’s cold wallet:

The importance of Watt’s steam engine invention is inestimable. It was widely used in factories and became almost The power of all machines changed the way people work and produce, greatly promoted technological progress and kicked off the industrial revolution.

It allows the location of factories to no longer depend on coal mines but can be built in more economical and efficient places. It also does not have to rely on water energy so that it can operate all year round, which further promotes the development of economies of scale. , which greatly improves productivity and also makes business investment more efficient.

The steam engine provides the possibility for a series of precision processing innovations. Higher technology ensures the performance improvement of various machines, including the steam engine itself. After continuous efforts to introduce higher pressure steam, steam trains and steamers soon followed.

D. Two disadvantages of the Watt engine

The disadvantages are that the thermal load capacity of the cylinder is not as good as that of the cast iron engine, the power potential is not as good as that of cast iron, and the corrosion resistance of aluminum is not as good as that of iron. And the price is much higher than that of cast iron..

E. Why is Watt called the first generation of modern technology experts

Watt was born on January 19, 1736. His father was a shipbuilder and engaged in various shipping operations and had a repair shop. His mother is a housewife with rich knowledge. Watt was born weak and withdrawn. He often took leave and was unable to go to school normally. Therefore, his homework was not very good. But his thirst for knowledge is very strong, and he especially likes geometry. Due to poor health, Watt did not graduate from high school, so he dropped out and returned home to study on his own. Watt later went to his father's factory to learn technology and operate various tools. After several years of training, he learned woodworking, metal smelting and processing, machinery manufacturing, instrument repair and other crafts, laying a solid foundation for later inventions.

In 1753, Watt's father failed in business, and then his mother died, leaving the family impoverished. The 17-year-old Watt was forced to go out to make a living and became an apprentice in a watch shop in Glasgow. Two years later, he arrived in London and became an apprentice under the famous mechanic Morgan. In 1756, he returned to Scotland. Watt wanted to start his own business making instruments, but because his apprenticeship was not long enough and did not meet the requirements of the municipal government, he had to be introduced by a friend and became a repairman of teaching instruments at the University of Glasgow under the jurisdiction of the municipal government. workers. Soon, a businessman donated a large number of astronomical instruments to the University of Glasgow, but they were very old and could not function properly. Watt took it upon himself to undertake the task of repairing the instruments, which were quickly restored. A professor sincerely praised: Watt is a young man with rich mechanical knowledge, very alertness and extraordinary talents.

In 1763, someone sent a damaged steam engine model to the University of Glasgow. Watt was assigned full responsibility for repairs and getting the machine started for student experiments. No one thought that this would be the beginning of Watt's great achievements in human history.

A steam engine is a power device that uses water vapor to convert thermal energy into mechanical energy. Humanity's understanding and utilization of steam has gone through a long history. After the establishment of the British constitutional monarchy, British industry developed rapidly. Machines such as spinning jenny and water-powered spinning machines were increasingly used. However, power issues became a "bottleneck" in expanding machine production. In 1705, the British blacksmith Nicoman made a "Newcomen steam engine" that could be used to pump water from mines. However, due to the shortcomings of excessive fuel consumption, only reciprocating linear motion, and uncontrollable temperature, it has not been widely used in other production departments.

What Watt was in charge of repairing was a "Newcomen steam engine". He quickly repaired the Newcomen engine model after accepting this task. But he was not satisfied with this. Through this repair, Watt learned more about the structure, performance and existing problems of steam engines, and developed a strong interest in it, as if he was obsessed. He observed that the piston of the Newcomen engine basically replaced human hands with mechanical power, but it could only go back and forth 10 times a minute, so the work efficiency was extremely low. He was determined to improve the design of steam engines.

Watt began to study the principles of steam engines and consider problems based on the principles of engines. He also studied the properties of steam, starting with concrete issues such as the consumption of steam and fuel, and then expanding to abstract issues such as the relationship between the movement of heat and engines. He conducted many experiments, but still could not come up with a specific method to improve the efficiency of the "Newcomen Steam Engine".

On a sunny Sunday afternoon, Watt was walking in the countryside, but his mind was still thinking about the steam engine. Suddenly an idea flashed into his mind: adding a steam condenser could make up for the major drawback of excessive waste of heat due to cooling and condensation of steam in the cylinder. He immediately resigned from his job at the University of Glasgow and devoted himself full-time to the prototype. In the rented basement, after repeated experiments, Watt and his assistants finally made a single-acting steam engine with a separate condenser in 1768, and obtained a patent application the next year. Watt's steam engine has more significant advantages than Newton's steam engine: it is safer, more reliable, moves faster, and consumes 75% less fuel. Everyone praised Watt's invention.

"No! It is only a single-action type. I also want to make a linkage type to make it run more smoothly!" Watt was not satisfied with his achievements.

In 1774, Watt moved from Scotland to Birmingham after the death of his wife. Work continued on the making and improvement of the steam engine, with the support of the manufacturer Bolton. In 1781, Watt adopted a planetary gear mechanism to change the steam engine from reciprocating motion to rotating motion. In 1782, Watt built a more complete linkage steam engine, which was four times more efficient. In 1784, he invented the parallel linkage mechanism, which made the steam engine more widely applicable. A year later, the first spinning mill powered by a steam engine appeared in Britain. In 1788, Watt invented the centrifugal governor and throttle valve. In 1790, a cylinder actuator was made, finally completing the entire invention process of the steam engine. Since then, the superior performance of the Watt steam engine has completely replaced the old Newcomen engine.

From a technical point of view, there is a qualitative difference between the Watt steam engine and the Newcomen engine. Part of the piston movement of the Newcomen engine is driven by steam, and the other part is driven by external atmospheric pressure. The Watt steam engine uses a sealed cylinder, and the piston movement relies entirely on the thrust of steam, so it can be called the first steam engine in the world. In addition, the use of centrifugal regulators in steam engines created the unit of power - horsepower, which was also credited to Watt. The centrifugal regulator is a device that controls the process through changes in the process itself. Although the rise of automation happened after the 20th century, it started with Watt. The word regulator, through the Greek, gives us a modern term - cybernetics.

From the perspective of research methods, Watt did not enter the ranks of craftsmen at that time, nor did he receive higher education. But he found a new way to observe, understand and study steam engines, which is to analyze how the engines work from both scientific and practical aspects. This is a modern technology expertWith his unique research methods, it is not an exaggeration to call Watt the first modern technical expert.

G. There is Watt under your pointer, Newton in your cold eyes, and Edison in your ridicule

From the perspective of teacher ethics, you should not treat students too much Criticize, students' innovation will be stifled by your ridicule and ridicule. The evaluation of students must be objective and multi-faceted. For example, if you love students, you should love students with learning difficulties and underachievers.

There are various kinds of love in the world, and the class teacher’s evaluation of the students is one kind of love. The class teacher gets along with the students day and night, understands the students in depth and detail, cares about the students sincerely, fully respects and trusts the students, and strictly demands the students, etc. are all love for the students. Educational psychologists believe that the love of the head teacher is different from the natural love of parents for their children. It is not only an attitude between individuals, but also contains more social content and has broad social significance. The class teacher's attitude towards students often reflects the student's collective and even some kind of evaluation of him by society. Therefore, students often associate the class teacher's care, love, trust, and evaluation with their status and personality value in the group. This emotion of the class teacher actually translates into an unusual psychological weight of social environmental factors in each student's mind. This shows how important the love of the class teacher is to educating good students!
Education cannot be without love, just like a pond cannot be without water. Suhomlinsky, an educator from the former Soviet Union, regards teachers' love for students as the "mystery of education". His motto is "Dedicate your whole heart to the children."
Experienced head teachers will have this experience. When students realize that the class teacher sincerely cares for and cares about him, whether you provide patient help, serious criticism or even necessary reprimand, the student will be happy to accept it. This is the so-called "be close to the teacher and believe in the teaching".
On the contrary, if the class teacher does not gain the trust of the students, then even if your educational goals are correct and your educational methods are scientific, your education will not be able to achieve the desired results. Because in the education process, students are not only the target of the teacher's action, but also show a "reaction" at any time. This reaction is reflected in the fact that the class teacher's teachings and requirements must be filtered or catalyzed by their emotions. If teachers and students do not reach trust, students will face the classThe head teacher's teachings will be indifferent, and severe punishment will lead to resistance and confrontational behavior. How can we educate students well with this kind of emotional conflict? I usually evaluate students in class meetings, and sometimes I evaluate students in front of some students after class. When filling out the quality report form at the end of each semester, comments will be written based on the student's situation. Educating students must follow the principle of teaching students in accordance with their aptitude. Students who are introverted and lack self-confidence must be encouraged, and students who are not strict with themselves must be severely criticized.
