On Saturday, I had a miserable day.
The thing is, after school on Friday, because I was too slow, I didn't finish a lot of homework, especially when the whole class finished their math homework and handed it to the teacher. But I didn't write a word about correcting my homework, so the teacher left me behind, and my father was very angry when he came to pick me up. Dad said, "Because you didn't take the time to finish your homework, I must give you a punishment to let you know how painful it is to waste time." After listening to my father's words, my heart was cold to freezing point. How should I spend tomorrow?
In this way, my painful day began.
After getting up at eight o'clock on Saturday morning, I finished my online English homework and began to write my five diaries. It turns out that my father asked me to keep a diary every day. My father is on a business trip from Monday to Friday, so I am lazy. Dad is very angry, and the consequences are very serious. As I wrote, I thought: What time do I have to go to bed tonight? It was already five o'clock in the afternoon when I finished writing my fourth diary. I feel dizzy, but I still have new concept English, two dark horses reading comprehension and a diary to finish. Oh, my God!
After dinner, I didn't even have time to rest and continued to catch up on my homework. I was writing, writing and doing, and before I knew it, it was twelve o'clock at night. At this time, I was really tired. I can hardly open my eyes, my hands and feet are cold and my ass hurts. So I knelt on the ground and wrote. After a while, my mind became confused and blank ... I wanted to sleep, but my father didn't sympathize with me at all. He told me not to sleep until I finished all my homework. Finally, I stayed up until 1: 30 and finished my homework. I simply took a bath and climbed into the cold bed.
I don't want to live like this anymore. I must do my homework quickly and get rid of my procrastination. A painful day taught me: first, do everything quickly and don't waste time; Second, the set plan must be implemented, and you can't find any excuse to be lazy; Third, arrange the time of each class reasonably to improve the learning efficiency.
I have a younger brother. How about I introduce him to you?
Brother 12 years old, a chicken. My brother has a handsome face, a pair of lively eyes hidden under thick eyebrows, two modest ears stuck to the sides of his face, and a slightly raised nose above an eloquent mouth. His skin color is not very white, but it is not black either. He looks fresh, energetic and radiant.
My brother is naturally fond of playing, much like a little monkey, jumping around together. He is called "full of energy". No wonder people say that he was born in the wrong year and should belong to a monkey. When eating, I often find an excuse to sneak out for a while. After being caught by an adult, I finished my meal like a whirlwind and continued to play with him.
Although my brother loves to play, he has a lot of things in his mind. Mathematics is his specialty, he speaks Chinese fluently, and he knows a little English, especially science. No matter what ancient creature you are, you are a few treasures.
Although my brother reads widely, he is not a bookworm. He likes nature very much, and also likes small animals, especially dogs. Recently, we went to eat noodles, and he gave half of his noodles to his master's dog.
My brother has an unrealistic ambition. When I was a child, because my brother was taller and bolder than me, others often mistakenly thought that he was older than me, and he boldly put forward it more than once.
There is something that can use the rushing river to help people irrigate farmland, pound rice and grind flour. This is a waterwheel. In Lanzhou, the surging Yellow River has endless hydrodynamic forces, and large and small waterwheels have become a landscape. No, I came to Waterwheel Expo Park and took a quick look.
Before I entered the gate, I saw two huge waterwheels in the distance. They are turning slowly, bringing up many glittering and translucent water drops. I ran over, looked at it carefully, and understood its working principle: there is a ditch under the waterwheel, and the Yellow River water flows into this ditch after turning into turbulence through a valve, pushing the blades of the waterwheel soaked in water and filling the wooden pipes between the blades with water. This barrel has only one opening, and the opening is upward when it comes out of the water, so the water will not flow out; Turn to a high place, open your mouth downwards, pour the water into the wooden canal, one by one, and lead the water to the place you want to use, such as water mill, water stone mortar and so on. Just as I was looking at the waterwheel, my sharp-eyed brother suddenly shouted, "Look, rainbow!" " "I immediately turned to look: Ah! Just above the water level of the Yellow River, a seven-color rainbow spans between the water surface and the waterwheel! I looked at the scene in front of me in surprise. This is the first time I have seen such a spectacle. This is probably because the water dripping from the waterwheel forms rain gas in the air, which reflects the sunlight. The position of the sun has been changing. We are lucky to see the rainbow!
We went to a water mill and bought two liters of corn. I saw two stone mills standing up and down in the room. The upper millstone is hung by a rope, and the lower millstone is spinning rapidly. The water just hit by the waterwheel arrived here, and the impact of the water made the millstone under the house rotate rapidly, thus driving the lower millstone to rotate. The tour guide aunt told me that most people pull the mill up and water mill down. We pour the corn into the hole in the upper mill, and the corn is crushed between the upper and lower mills and scattered on the board under the lower mill. We put the ground corn on something like a sieve bucket. I stepped on the pedal up and down, and it immediately moved left and right. Corn flour falls into the right grid through the gauze at the bottom of the screen hopper, and corn grains fall into the left grid from the left opening in the turbulence. How interesting!
Lanzhou waterwheel skillfully uses the great power of the mother river to save manpower and material resources. It is not only a wonderful invention, but also a true portrayal of the perseverance, intelligence and hard work of the ancient working people.
Zhou Ji junior high school article 4 Spring is coming! What a beautiful campus!
Grandpa Dong slowly left everyone, and Miss Chun came to me quietly. There are colorful flowers everywhere, and butterflies and bees are busy collecting honey. Of course, the campus is just as beautiful.
Camellia has exposed its beautiful buds and started a new life. Wisteria grows so fast!
In the corridor, I suddenly smelled a fragrance. You don't have to look at it to know it's winter jasmine. Its yellow mouth in Zhang Kaiming said to me, "Hello, hello, I am Miss Chun's' Master'."
I really like the campus in spring!
Zhou Ji junior high school article 5 Time flies, the sun and the moon fly, and in a blink of an eye, I have lived in junior high school for half a year. When I first entered junior high school, I was faced with big and small problems: where to buy a meal ticket? where is the dining room？ Where is the office? And ... and when I first arrived in junior high school, because of the increase in subjects, the difficulty increased and my grades fell behind. But in the end, I got used to this new life bit by bit, and my grades went up bit by bit. From 2 1 to 13, and then to the eighth and fourth place. ...
Now, I have become a good student recognized by the teacher. Test scores have repeatedly become the first in the school. In junior high school, I got less criticism and more praise; Self-motivated than before, and the results have risen linearly; The stronger the self-awareness, the less severe the parents are. Because I have grown up.
Unconsciously, I spent two months in junior high school. I gradually get to know my classmates, and I can communicate with them. I also know the advantages and disadvantages of teachers and their different styles. On the contrary, teachers have gradually learned about us, knowing our names, hobbies, personality differences, learning characteristics and so on. We have regarded this class as a big group, and everyone is United and friendly and helps each other. Everyone remembered the name of this group-Class 5, Grade 7.
Before the New Year's Day Gala, everyone actively participated and signed up. At the gala, many people performed dances together, one solo, several people had a whim to perform comic sketches together, interactive games that everyone participated in, and … At the end of the gala, everyone was reluctant to go, because it was only once a year.
Life in junior high school is naturally easy-going, happy and warm. In this big group, everyone learns from each other, improves each other and enjoys learning. What is wrong with such a good life?
One summer evening, my father rode a bicycle and said that he would take me to Lixian to see the world. I felt uneasy all the way, and time passed so slowly that I really wanted to fly to my destination at once.
There are many buildings there, which are especially beautiful under the light. I thought this was a lawn! There are some Rubik's cube-shaped trash cans and stools on the roadside to provide some convenience for tourists. There are also spacious main roads, and everyone parks their cars in parking lots far from bicycle lanes. After walking for a while, I found something that looked like a Rubik's cube everywhere, so I said, "Why are they all the same shape?" Can't designers be a little innovative! " Dad laughed at me.
Suddenly, my father pointed to the front and shouted, "Look, what is that?" As soon as I looked up, I saw a green overpass floating in front of me like a green belt under the light. So this is the "water sleeve" that I miss day and night! I looked at the introduction and was shocked: Mom, it is more than 860 meters long. I'm afraid I'm exhausted before the end! My father and I talked and laughed all the way, and it ended before we knew it. It seems that she is not as long as I expected. When we came back, we deliberately followed a maze-like path to find the fun of the path. Out of the maze, we went home by bike.
I am very happy today, because "free travel" let me know that we also have beautiful scenery in Lixian County, which makes me feel very proud and proud. I will study hard and build our hometown better in the future!
On Saturday morning, it was clear in Wan Li. My mother and I went to the market to buy food.
Before we got to the vegetable market, the shouts of selling vegetables, the bargaining of customers and the honking of cars got into our ears. Look, there are vegetables, water, candy, meat and sundries.
On the vegetable stall, there are tomatoes, eggplant and Chinese cabbage; On the fruit stand, there are apples, pears and oranges; There are eggs, mops and rice on the sundry stand; There are chickens, ducks and pigeons on the meat stall. ...
These customers are more diverse. Some bow their heads to smell vegetables and pick vegetables; Some are holding vegetable baskets and talking to themselves about what to buy; Some look around and say that this is not good, so it won't work; Others happily returned home with food baskets.
We came to the meat stall to buy meat. I found that hens in cages also have different looks: some don't care about being killed, but still eat rice with relish; Some people don't eat or drink, sometimes they look at the sky, as if eager for freedom, sometimes they look at the chicken slayer, as if begging the chicken slayer not to kill himself, and sometimes they look at the dead chicken in the hands of the chicken slayer and shudder; Some of them are fighting with each other. It's funny that you pecked and kicked me. There are also pairs of whispering, as if discussing how to escape. Chicken killers skillfully kill chickens with blood-stained hands and cut and weigh the meat. Mother took the meat and took my hand and left.
Going shopping today not only enriched my knowledge, but also made me feel endless fun.
It is understood that most teachers attribute students' learning difficulties to factors other than teachers, such as difficult subject content, poor students' quality and poor family education environment. Only a few teachers think they don't teach well. Students think that they have difficulties in learning, and about one-third of the reasons are already in the teaching and management of teachers. Some people even put forward the view that there are no students who can't teach, only teachers who can't teach.
These fully show that teachers are responsible for the formation of students' learning difficulties. Therefore, as a teacher, we should deeply reflect on our teaching behavior, so as to reduce students' learning difficulties. In mathematics teaching, reflection is the source of finding problems, a good way to optimize teaching design and improve teaching quality, and a reliable way to promote the sublimation of understanding. Confucius, an ancient philosopher in China, once said, "Learning without thinking is useless, and thinking without learning is dangerous." Foreign scholars have also expounded the importance of reflection.
For example, Friedenthal, a Dutch mathematics educator, once said: Reflection is an important mathematical activity, and it is the core and motivation of mathematical activities. Posner pointed out that the growth of teachers = experience+reflection. It can be said that the experience without reflection is only a narrow experience, and at most it is a superficial understanding. Reflection can rectify the existing problems, explore the problems found in time, and sublimate the accumulated experience into theory. Reflection can also improve mathematics consciousness and optimize thinking quality. So what should we reflect on after class? Here are some of my views for your reference:
First, reflect on the teaching objectives.
Teaching objectives refer to the concepts, methods, familiar skills and mathematical ideas that students need to understand in this class, which is the basis and premise of teachers' further teaching and the necessary condition for students to improve their comprehensive ability. Teachers' reflection on teaching objectives is actually to discover whether Chu students really understand the connotation and extension of the concept, the premise and conclusion of the theorem through reflection on the teaching process; Can you use the theorem flexibly to solve problems, the thinking method contained in the theorem itself, the scope of application of the theorem, and whether the basic methods to be mastered in this lesson have been mastered. To know all this, we should first pay attention to students' every move in class. If the students in class are focused, positive, agile and happy, it means that the students are enthusiastic, take the initiative to participate, learn something and have fun.
If students are listless, deaf, procrastinating, exhausted and at a loss in class, it shows that the classroom atmosphere is dull, students' enthusiasm is not high, learning is very hard and the effect is not good. Secondly, check the situation of students doing classroom exercises. If most students can correctly complete the specified topics within the specified time, the teaching objectives can basically be achieved; If most students can't write or can only do some steps of the project, or even if they do, there are still some problems, which means that students have not really understood the content of this section and their knowledge and skills have not passed the test. Thirdly, review students' homework after class. If students have clear thinking, well-founded reasoning, proper use of theorems and formulas, accurate calculation and detailed steps, it shows that students have mastered basic mathematical knowledge and thinking methods. On the contrary, if students do flip-flops, confuse formulas, misuse theorems, and make constant calculation mistakes, it shows that students' basic knowledge and skills are not enough. Through the above series of methods and means, find out the problems and think about remedial measures. What should be supplemented must be supplemented, and what should be changed must be changed; What is emphasized collectively must be emphasized collectively, and what is suggested by individuals must be suggested individually. Make up the content of the class for later study.
Second, reflect on teaching methods.
Teaching methods are measures and auxiliary tools to complete teaching tasks and achieve teaching objectives. As the saying goes, "there is a law in teaching, but it is impossible in teaching." The choice of teaching methods depends on students' actual cognitive level. Usually, according to the different teaching contents, teaching methods such as lecturing, heuristic, discovery and questioning can be adopted, and wall charts, models, objects, small blackboards and multimedia courseware can also be used to assist teaching. To reflect on teaching methods, we must first break through the most difficult, difficult to understand and difficult to master in their study, start from the most boring places, and start from the places that they are easy to ignore but rich in teaching value. Secondly, teachers should seek the best teaching form that is most conducive to students' acceptance, students' acceptance, students' enthusiasm for learning, students' scientific creativity and students' coordinated development in all aspects.
If the introduction of the topic is too dull to arouse students' interest in learning, students can be explained the growth process of mathematicians, novel mathematical problems, mathematical problems around them and so on. If the deduction of theorem and formula is proved to be limited to textbooks, students can not understand it easily, so they can explore new ideas and change strategies to satisfy students' thirst for knowledge and stimulate their creativity in scientific knowledge with rich content, easy to understand and step by step; If the treatment of example exercises is lack of depth and students can't master it well, we can explain it in simple terms and draw inferences at different levels, and try our best to cultivate students' concentrated thinking and divergent thinking on the premise of mastering basic methods and skills. As long as we observe and think about goodness, we can gradually improve our teaching level and quality.
Third, reflect on the teaching value.
Teaching value is the sublimation of teachers' teaching goals, students' teaching significance, thinking cultivation and moral sentiment when they complete their learning tasks, and it is a higher realm of education and teaching. There is an educational motto that says well, "education is a cause that needs our selfless dedication;" Education is a science, which needs us to study hard. Education is an art that needs constant innovation. " Reflecting on the teaching value is to explore the value of cognitive education, emotional education and behavior education which are rich in this course.
We should know that every mathematical thought contains a philosophy of life, every problem-solving method enriches students' values and world outlook, and every bit of mathematical knowledge purifies students' hearts. As long as we carefully observe, carefully analyze, think deeply, strive to expand, let go of the clues in classroom teaching and the words in textbooks, we will certainly be able to do it and do it well. For example, the idea of classified discussion teaches students to look at problems dialectically, and the idea of function teaches students not only to pay attention to the phenomenon of problems, but also to recognize the essence of problems; The combination of numbers and shapes teaches students what mathematical beauty is, how to appreciate it and how to use it. Reducing to absurdity makes students realize that it is not necessary to attack directly to solve problems, and sometimes it is better to detour sideways. The growth process of mathematicians can set an example for students and inspire them to study hard; The long and splendid history of mathematics development in China can make students have a strong sense of national pride and stimulate their patriotic enthusiasm, so as to study hard and devote themselves to the modernization of the motherland.
Modern education is not to teach a group of nerds, not to teach a group of high scores and low abilities, but to think about students' future and make necessary knowledge preparation and psychological preparation for their colorful lives. Knowledge is dead, ignorance can be learned from books, while ability and quality are intangible and cannot be taught. A person's quality determines his viability and development prospects. In the final analysis, the value of teaching has been shaping people, giving students the truth of being a man, giving students a scientific way of thinking and the basic quality of self-development, so that they can all become useful people to society.
Zhou Ji Junior High School Chapter 9 During the Ching Ming Festival, there are many rains, and pedestrians on the road want to break their souls. Excuse me, where is the restaurant? The shepherd boy just laughed and didn't answer Xingshan Village.
Every year when Tomb-Sweeping Day approaches, there will always be a faint and inexplicable sadness in my heart, which is not very strong, but it is also lingering, so it is entangled and entangled in my heart. The weather is very good these days. I don't know if it will rain in Mao Mao on that day in Tomb-Sweeping Day. It seems that with this rain, Qingming can show its faint sadness.
Gradually, for me, Qingming is a bit more sad and heavier, especially after Taigong left. In my impression, Taigong is a kind old man. He is very kind to me, perhaps because I am good. After Taigong left, every year Tomb-Sweeping Day and his memorial day will feel very sad. Some people say that other people's thoughts will fade with the passage of time. I think, maybe missing relatives is just the opposite; Although it has been a long time, every time I think of their voices and smiles, I always feel a little sour in my heart! Even if it is ten years or decades, this feeling will not weaken or disappear, but will be stronger. Because of this, Tomb-Sweeping Day will become a day that has been circulated for thousands of years; The drizzle in Tomb-Sweeping Day will come one after another, which is probably a sad feeling in people's hearts.
