In the first physics class of the new semester, some newly transferred students in the class don't know the course progress, and some newly transferred students in the class don't know the course progress.

(1) Correct. Because Zhang Qiang violated the rules and regulations of the school and affected the normal teaching order, Teacher Wang's criticism is also a responsible performance for the whole class.

(2) Zhang Qiang should take the initiative to explain and communicate the real situation to the teacher after class, instead of talking back to the teacher in class, hurting the teacher and evading responsibility. Zhang Qiang's talking back to the teacher in public is a deliberate injury to the teacher and a sign of disrespect for the teacher. When interacting with the teacher, you should learn to put yourself in the teacher's shoes, forgive the teacher's mistakes, be polite to the teacher, pay attention to the occasion, and do not lose your discretion.

How to teach the first physics class, the first physics teacher? Is to give students a definition. . Talk about your views on physics and students. I don't need any specific knowledge, just say it. . For example, the literary interpretation of physics is to study things and so on. . Cooperate with some simple experiments and life phenomena to show the mystery and beauty of physics. . Arouse students' interest. .

It is easy for students to take physics class for the first time. . Put down the pen and paper. Put your hands on your head. Listen with your heart and imagine with your heart. . Just observe with your heart. .

How to have a good first physics class? Mainly to make students interested in physics. How much knowledge students learn in the first physics class is secondary. The key is that teachers should use multimedia to show some beautiful pictures related to physics, demonstrate experiments and introduce famous physicists. Teachers should also organize students to do a few small experiments themselves. Through these, let students have a strong interest in our physics subject, so that students will be willing to listen and learn in the future.

How to attend the first physics class in the first day of junior high school? I remember previewing in advance in junior high school, so I think you should look at physics in advance and cultivate your interest. Listen to the teacher carefully in class. If you don't know how to write it down in time, ask your teachers and classmates.

Help, how to attend the first physics class? New teacher bar

1, correct your mind and relax.

2, prepare lessons must be sufficient, what content should be talked about in this class, and the transition between content and content should be designed.

3, the expression is clear and accurate

How to teach the first class well in the new semester is very important, and it is the teacher's first appearance. The first impression will affect the next communication between teachers and students. Therefore, teachers should carefully design classroom teaching, not necessarily taking new lessons immediately, but "warming up" students before learning new contents of textbooks, so that students can correct their learning objectives, establish learning confidence and cultivate their interest in learning. Let's talk about how to guide students' learning methods:

First of all, students are required to be fully prepared before class. Mainly do the following: First, prepare knowledge, ask students to browse the teaching materials before class, and know the general outline of the relevant content when the teacher wants to attend class, so that they can have a clear idea when they attend class, and they can cooperate with the teacher to attend classes with a purpose and focus, without being passive, so that they can learn more actively and have better results.

Second, we should prepare the materials well. Before the teacher enters the classroom, every student is required to put away the relevant learning tools and turn over the textbooks and related contents. Although these are trivial things, the purpose of doing so is to adjust the mood of the students and let them enter the learning state as soon as possible.

The third is psychological preparation, which requires students to adapt to the teacher and pay attention to discovering the advantages of the teacher (such as erudition and humor). ), because only by kissing his teacher can he believe it. Don't look at others with a magnifying glass or colored glasses, and stay away from others. In fact, it is also an excellent quality to tolerate others, accept others and deal with people well. Why didn't we have this excellent quality before studying? Of course, every teacher has his own personality and specialty. He learns to deal with teachers of various personalities, and he will also be influenced by various behaviors, because the world is rich and colorful, which will make his personality more perfect. We know that the sun also has black spots, people's fingers also have shortcomings, and teachers certainly have shortcomings. We should learn to foster strengths and avoid weaknesses. Everyone has heard the story that the same thing is half a bottle of water. Optimists will say there is still half a bottle of water, pessimists will say there is only half a bottle of water. Therefore, we should pay attention to adjusting our mentality and devote ourselves to learning with a good mental outlook. Other psychological adjustments, such as preparing for primary school, preparing for junior high school, preparing for senior high school and preparing for college, should also pay attention to thinking less about what happened in last class and between classes, and think more about some pleasant things to stimulate their interest and activate their thinking.

Second, students are required to listen attentively in class. People's energy is limited, and it is impossible to learn everything in class. Therefore, we should pay attention to the methods in class, that is, ask students to pay attention to the key points and listen to ideas when listening to the teacher's explanation, so as to improve the learning efficiency in class and get twice the result with half the effort. What's the point? Usually it is the content of the teacher's blackboard. The textbook is illustrated with pictures and texts, and the teacher focuses on explaining it. After-class exercises also have related contents. Third, we must learn to eliminate interference. Some students have developed bad behavior habits, such as urinating in the middle of class, eating in class, sleeping on their desks without learning to control themselves, and doing things unrelated to class, such as listening to MP3 and watching MP4. We should consciously put an end to these bad behaviors. These behaviors should be developed in primary school and need not be emphasized here. The third is to cultivate interest in learning. Everyone knows that interest is the best teacher. With interest, you will have the motivation to learn, and you will find your own pleasure and sense of accomplishment in learning. If you learn well, you will love learning more. Only in this way can a virtuous circle be formed. We are required to overcome difficulties psychologically and be strong-willed. "It's not difficult for me to learn the dictionary by myself!" "I'm interested in biology! "You can pretend to do it, that is, if you are not interested in it, you will be really interested, and then it will become a real interest. Always take notes in class, try to be eye-catching, grasping hands and mouth, pay attention to these and follow the teacher's ideas, so that it is not easy to doze off in class and give full play to the brain's potential for a long time.

Third, review in time after class. My request is not high, that is, I spend a few minutes reviewing what I learned that day after class every day, that is, I just need to look at it once, so I don't have to worry about remembering it. It's better to watch than not to watch. According to Eshaubin's natural forgetting curve, the law of forgetting is fast first, then slow, and then rarely forgotten. If you can review it in time, you can greatly improve the memory effect and greatly reduce the number of forgetfulness. Everyone should make full use of the following memory rules: if the best time to remember is in the morning and evening, don't worry about forgetting, it's normal. For example, if you remember 100 questions every day, suppose you forget 80 questions and remember 20 questions, and it will be the same tomorrow. In this way, although you forget a lot, you will remember a lot. If people have the confidence to remember things purposefully, the memory effect is better, such as remembering useful names and mobile phone numbers. Who doesn't remember them? Repeated memory is also effective. Repeat a question for more than three times and you will remember it firmly. Try it if you don't believe me! Of course, there are many ways to remember, such as comparative memory, chart memory, map memory, understanding memory, multi-channel memory, jingle memory and so on. Everyone should use it flexibly in future study.

How to have a good first English class in the new semester? Hello, teacher! I have a special liking for English teachers ~! Really. )

You should be familiar with the textbook. Of course, preparing lessons well is the most important thing.

When you meet students for the first time, you should be very friendly and make them think that you are sociable. As long as the lectures are lively and interesting. Students like this.

My answer is simple, but it must be effective!

I'm a student in grade eight now. Can I make friends with you? I'll ask you questions later (English is my favorite subject. )

The first physics class composition 200 the first physics class

Wang Cong, Class Two (1 1)

In life, we can't live without a subject-physics. And physics seems so difficult, it seems that people who have never touched it are discouraged. I have long wanted to learn physics, and this year I finally ushered in the subject of physics. And I am both happy and afraid of physics. I am glad that I can do experiments, explore and find answers by myself. I'm afraid that physics is getting more and more difficult, and people like me who are "simple in mind and developed in limbs" will know nothing. So I'm crazy about physics!

However, our first physics class is very interesting! This course mainly focuses on experiments. The teacher gave us several experiments first-which of the two candles went out first in a sealed lid? How does the gong sound spread? Can the cell phone receive a signal in a sealed metal box?

The experiment done by the teacher immediately aroused our interest, and we couldn't wait to do it ourselves. At this time, the props we prepared in advance also came in handy. We read the words in the book through a glass full of water, and the words became fat. Although it is similar to a magnifying glass, it can't be higher. What happened?

Next, we did a more interesting experiment. We pour half a bag of salt into a glass filled with clear water and keep stirring. We found that the color of water changed from transparent to white. Then put the raw eggs in salt water and observe carefully: I found that the eggs floated in the center of the cup, and no matter what measures were taken, they could not sink to the bottom of the cup. What is the reason?

Because we brought raw eggs, they broke at the touch. No, both their eggs were broken. There are egg whites on the table cover and schoolbag, and the eggshells are scattered all over the table. It's really embarrassing. What is more interesting is Chen's egg, because he is carrying a small water cup, which is difficult to put down and even more difficult to pick up. This is very painful for him. What's more, his eggs are "different" from ours. The egg sank to the bottom of the cup at a time, but it couldn't float, which made the owner of the egg anxious, and his * * * made everyone around him laugh. I gloated aside and deliberately showed off my floating eggs, which made him speechless with disgust. ...

A physics class experiment is over! I really look forward to what surprises the teacher will bring us in the next class. ...

How to teach the first math class well in the new semester is good? There is no need to care whether it is the first and last place or a certain class.

How to teach science well in the first class of the new semester? I'm talking about my own evolutionary history of the universe. The students are very interested, and the class will be quiet in the future:

Evolution history of the universe: (scientific paper, original by Cai Lin of Qingshan Lake in Nanchang)

Before the formation of our universe, it was a huge ellipsoid primitive universe. There are many huge primitive black holes in the primitive universe, which have extremely high density and extremely high temperature and constantly absorb the energy around them. There are many parallel universes in a black hole. Because black holes keep absorbing energy, they get bigger and bigger. When the energy reaches overload, the black hole will release energy, which is called "Hawking ray", producing wormholes, releasing singularities, producing a big bang and forming today's universe.

About 65.438+0.382 billion years ago, the universe was formed by a strange big bang (this is a theory that scientists derived from the reverse thinking that a large number of galaxies quickly left us). When the explosion reaches 0. 1 s, the high temperature of 1000 billion degrees is generated. There is nothing in the universe at this time, but time has begun and space is expanding. 65.438+0.375 billion years ago, temperature of the universe cooled first and then slowed down, and the earliest elements appeared in the universe: hydrogen and helium, which are the most basic and important elements in the universe; When four hydrogen atoms get together, they will produce nuclear fusion and form helium, which can attract surrounding nebulae to form planets together. 65.438+0.37 billion years ago, many massive stars were born in the universe. Because massive stars consume a lot of energy and die quickly, billions of years later, massive stars are constantly destroyed, resulting in many nebulae, clusters and life elements in the universe. 65.438+0.36 billion years ago, the earliest galaxies and galaxies were born in the universe. 654.38+065.438+00 billion years ago, elements such as nitrogen, oxygen and iron were born in the universe. 9 billion years ago, a large number of nebulae and clusters were born, and 7 billion years ago, a large number of stars were born. Nebulae, star clusters, galaxies, black holes, stars, supernovae, neutron stars, black dwarf, white dwarfs, red giants, planets, dwarf planets, satellites, asteroids, meteors, comets, dark matter, dark energy and other substances are gradually and constantly changing.

The history of human evolution can be traced back to the emergence of the solar system. About 4.5 billion years ago, the sun and solar system formed at a distance of 30,000 light years from the center of the Milky Way (black hole). 4.4 billion years ago, the earth was formed in the solar system. 4.37 billion years ago, a planet the size of Mars hit the Pacific Ocean of the Earth, causing it to fly out, forming the moon, the satellite of the Earth. At first, the earth was a fireball, spinning very fast counterclockwise. Four billion years ago, a large number of ice meteorites in the universe arrived on the earth with life elements, forming oceans. 3.6 billion years ago, the water in the ocean, the temperature of the volcano and a small amount of oxygen ejected from the submarine volcano activated amino acids, the life element in seawater, and formed the earliest life on earth-cyanobacteria. 2.9 billion years ago, the earliest plants: algae plants, 2.3 billion years ago, the earliest animals: prehistoric marine mothers, 654.38+0.5 billion years ago, prehistoric marine life.

So, how did we humans evolve? About 500 million years ago, spiny fish (prehistoric shark) appeared and was considered by scientists as the earliest known human ancestor. (The first ice age occurred in Precambrian 570 million to 680 million years ago, and glaciers covered Europe, America, Asia and Australia; The second ice age occurred 4. 1 100 million to 470 million years ago in Mesozoic, and glaciers covered Europe, Africa, North America and South America. The tertiary ice age was formed in the Permian between 230 million and 320 million years ago, and glaciers covered the whole earth. The Quaternary Glacier Period was produced in the Cenozoic from 65 million to 2.5 million years ago, and glaciers covered the whole northern hemisphere. When glaciers come, the climate on the earth will change greatly. The temperature will drop by 10℃ to 15℃, and the sea level will drop by 130 meters, resulting in a large number of species extinction. ) 300 million years ago, prehistoric sharks evolved into prehistoric triangle fish, 200 million years ago, they evolved into amphibians-prehistoric salamander fish, and 654.38 billion years ago, they evolved into reptiles-like chicken dragons. The dominant position of dinosaurs on the earth reached 65.438+0.5 billion years. At that time, animals were big because the oxygen content in the air reached 4.88. 65 million years ago, an asteroid with a diameter of 20 kilometers hit Mexico's Yucatan Peninsula, and the earth's environment became extremely bad, leading to the extinction of species on earth. 45 million years ago, little dinosaurs evolved into birds and mammals. Birds interbred to lay eggs, and other birds hatched cocks and hens at the same time. At this time, humans evolved into rodents-Pulgatory monkeys,/kloc-0.5 million years ago, into mammals-apes, 7 million years ago, into homo sapiens, and 5 million years ago, into highly intelligent creatures-modern people.

At present, humans have been able to observe the universe in the range of10 billion light years with radio telescopes, and10 billion galaxies similar to the Milky Way have been discovered, but the edge of the universe has not been discovered. The universe is still expanding like a balloon. The universe expands first, then slowly (explosive energy is greater than dark energy), and then quickly (explosive energy equals dark energy). (Dark energy is greater than explosive energy) Eventually the universe will be torn apart. Black holes are formed by supernova explosions of massive stars. When it is formed, it will devour the surrounding interstellar matter, even light. Then, the big black hole will swallow up the small black hole. About 654.38+00 billion years later, the universe will return to the original parallel universe, and everything will start again.
