1 overall feeling
Starting from the concept of the new curriculum, the teacher adopts the teaching mode of gradual deepening in stages, creating an open classroom and a dynamic classroom for students, fully allowing students to carry out cooperative learning and autonomous learning. In a relaxed and equal atmosphere, let students try their best to taste the joy of the success of scientific inquiry activities, and implement the goals of knowledge and skills through teachers' examples and exercises. From the introduction of games, the contrast between elephants and ballerinas, the application of pressure and decompression, and the investigation report of pavement damage left after class, all reflect the teachers' thinking of moving from life to physics and from physics to society. Control variable method and analogy method are interspersed in classroom teaching. Teacher Li is generous, kind and natural, and her blackboard writing is standardized. This class has achieved good teaching results.
2 highlights in the teaching process
(1) Introduction-A scene in which boys and girls compete to cut radishes was created in the form of a competition, which caught the students' eyes at once and aroused their interest. Because interest is the best teacher for students, and it is also the continuous motivation for students to carry out inquiry activities. How to turn a secret of cutting radish into a concrete physical problem when entering a new class? Teacher Li embodies the role of classroom guide. Through three pictures, she guides students to get the concept of pressure through the similarity of * * * in the pictures, emphasizing under what circumstances pressure equals gravity, paving the way for students to ask questions, guess and assume.
(2) Inquiry part-students' enthusiasm and initiative are brought into play. Students experience and observe from beginning to end. For example, a comparative experiment with different effects was made with the tip and cap of a pencil available at hand, which was close to life and gave students a profound experience. For example, in the aspect of making plans and designing experiments, although the textbook introduced this aspect, Mr. Li did not stick to the textbook and talk on paper, but let the students go through this stage completely, which improved their ability to design experiments. Some students designed an experiment, using the same piece of plasticine to compare the different depths of the rope to plasticine at different tension, which is very good.
When designing experiments, teachers are completely integrated into students and become their partners. Help and guide students in time when they encounter difficulties. What method should be used in the experiment? How to show the effect of stress?
In these processes, students' ability to design experiments and apply scientific methods has been greatly improved. The atmosphere in the classroom is harmonious. In the teacher-student interaction and student-student interaction, students collect information, actively look for the causal relationship in the phenomenon, and summarize it. The last two students came to the stage to communicate, which cultivated students' ability of unity and cooperation, logical thinking and oral expression.
(3) Pay attention to methods in knowledge dissemination. For example, in the process of scientific inquiry, students are inspired to design experiments by controlling variables, and when the concept of pressure is introduced, students can compare the concept and expression of speed. Students' scientific literacy is gradually improved by teachers' methods.
(4) standardization. When teaching examples and students show the process of solving problems through video display platform, Mr. Li has made further standardization and training in writing, units and scientific counting, so as to cultivate students' logical thinking and rigorous scientific attitude.
(5) Multimedia assistance and blackboard writing complement each other. Multimedia shows beautiful pictures and stress analysis, video shows the problem-solving process, and the blackboard writing is standardized and beautiful, which complement each other. Courseware can only show teachers' preset teaching resources, but the classroom is dynamic. Use reasonable and standardized blackboard writing to adjust and supplement the teaching content, so that the classroom is real and vivid. 3 Suggestions for improvement
But there is no fixed teaching method, and every teacher has his own views and practices on each class. I will talk about some points that I think are worth discussing, and my suggestions for improving the teaching of this course.
(1) In the introduction part of the classroom, games and competitions can arouse students' interest in inquiry, but attention should be paid to the convenience and safety of the experiment. The students are not skilled in using knives. Examples of stress can be found everywhere in daily life. I suggest that we can compare the difficulty of cutting soap with thin thread and string to compare the effect of pressure.
(2) In the teaching of concepts, we should pay attention to students' understanding and break through the difficulties. The concepts of pressure and pressure in this section are difficult, and students are prone to make mistakes. Therefore, attention should be paid to it in teaching. There are two key words in the concept of stress:
Vertical and surface. In pressure, the size of pressure and the size of stress area in pressure expression should be consolidated and understood through effective teaching methods.
(3) In the process of inquiry, what does Miss Li want students to think about first, which will affect the effect of stress? Let the students experience the pencil experiment, I think this is not in line with the students' cognitive law. Whether to let students experience the experiment first, find problems, ask questions and guess in the experience.
(4) When students make guesses, teachers should not have too many directional traces of guesses, otherwise exploratory experiments may become confirmatory experiments. When I was in this class, some students suggested that the effect of pressure might be related to the material of the contact surface. After fully demonstrating the students' conjectures, the teacher gradually screened out the main factors, secondary factors, factors related to departments and irrelevant factors, and determined the topics to be discussed. Students' thinking should not be restricted by teachers' various reasons.
(5) During the experiment, teachers and students can fully communicate and cooperate to make some phenomena more intuitive and obvious. If the deformation effect of the sponge is not obvious in students' experiments, you can choose a sponge block with soft texture and large volume, draw some black and white squares on the side of the sponge, and show different pressure effects through the change of grid shape.
Expand:
First, teachers are of good quality and the teaching atmosphere is positive and harmonious.
Whether a teacher's basic skills are solid, whether his knowledge is accurate and extensible is often the premise of evaluating his educational and teaching ability. Secondly, whether the teacher's body language and oral expression are appropriate is also one of the factors that cannot be ignored. Especially in physics class, teachers must have strong on-site control and adaptability, and be passionate, so as to encourage students to actively accept knowledge in a relaxed and pleasant atmosphere.
Second, the evaluation of instructional design
According to the new round of basic curriculum reform "Physics Curriculum Standard", the teaching design concept must "let life go to physics and let physics go to society". The classroom must follow the principle of "learning in the state of inquiry", with complete design, compact structure and strict logic, so as to achieve the effect of echo.
Third, the evaluation of the teaching process
1 Introduce new courses to make physics come alive. The teacher created a real life scene: let the students simulate the wires that go to the store to buy home appliances. And thus launched a heated discussion. Let students understand that even the little things in life contain unknown physical knowledge and stimulate their desire to learn. Make the whole class full of fun.
2. Give priority to inquiry learning and pay attention to the diversification of teaching methods. This class has created a strong atmosphere of inquiry, both in structural design and practical operation, so that students are actively thinking and exploring from beginning to end. For example, independent thinking, cooperation and group competition are designed for students, so that they can learn from each other and promote each other, so that all students can understand the "scientific inquiry process" and "scientific inquiry methods". Colleagues who teach students physics knowledge also teach students scientific inquiry thinking and the scientific spirit of seeking truth from facts. This is the biggest gain for the students in this class.
3 bold innovation, so that teaching resources closer to life
For example, let students compare the similarities and differences between iron wire and copper wire; An experiment designed by teachers on the influence of temperature on resistance. These novel designs have obvious effects and experienced teachers' unique innovative consciousness. Colleagues also made students understand that scientific inquiry is not an unattainable mysterious river.
4. Design homework gradient according to students' different cognitive needs.
This lesson designed an assignment: wiring the newly bought electrical appliances at home. This in itself transcends the traditional discipline-based concept, makes classroom life and discipline life, makes students understand that there are scientific reasons in life, encourages them to try and explore bravely, and expands the space for students to think and use knowledge.
5 people-oriented, pay attention to the cultivation of emotional goals
In the whole classroom, students are always the center of teaching activities, and teachers only play a guiding and transitional role. With the help of teachers, students actively participate, experience, cooperate, discuss and communicate, and everyone has gained the experience of exploration and success, and fully experienced the spirit of the new curriculum standard of quality education.
Fourth, teaching suggestions
Teachers are not only disseminators of knowledge, but also explorers and researchers of educational science. This lesson sets a good example for teachers, telling us how to get closer to students and how to educate students in all directions while imparting knowledge.
Extended reading: comments from physics teachers at the end of senior high school
1, the student studied hard, had a correct attitude and got excellent grades. He likes to unite with his classmates, loves his work and can be strict with himself at ordinary times. He can listen to the teacher carefully and has his own study plan and wrong book, which is very helpful for the review of senior three in the future. On the eve of the college entrance examination, the wrong question book is a very useful helper. I believe that with it, you will get good grades in the college entrance examination. In addition, I hope you can set a long-term goal. Only when you have a goal can you learn and have the motivation to work hard for it.
2. You have the desire to make progress, strong acceptance, and are an honest, enterprising and diligent good student. Take an active part in class activities and win glory for the class with your own ability. Your investment in study will definitely pay off.

I really like to see your sunny smile. I sincerely hope that you can be so relaxed and beautiful every day in the future. However, in today's increasingly competitive world, we need to take every class, homework and exam seriously. In the past semester, you have both success and failure. There are rich fruits and bitter tears ... but no matter what, you are strong and always upward. You are serious, diligent, open-minded and honest, so you have won unanimous praise from teachers and classmates. But sometimes you lack the confidence to win and are too hard on yourself. Actually, I know you are excellent. I believe that through your unremitting efforts and scientific methods, you will certainly achieve the due results.
Although I am unknown on weekdays, I am always in class activities. Have the ability to do things independently, don't follow others' advice, and have opinions when things go wrong. Study hard and behave well. Tenacious willpower and fighting spirit infect everyone and are worthy of being an example for the whole class. Study harder in the future. I believe that with your perseverance and patience, you will certainly make greater progress.
This semester, we have a closer relationship with other class cadres and formed a strong cohesion. You can make up for it in class at ordinary times, which is a new progress made this semester. You have contributed a lot to the class work. Blackboard, crazy list and so on all left your handwriting. I believe it will be a unique memory in the future. Your prestige is very high, your character belongs to the gentle and honest type of traditional Confucianism, and you are steady and reliable in doing things. The only regret is to study and make sure that you are in the top 500 in every exam.
6. In the teacher's impression, you are showing off your wisdom. Usually seemingly unknown, I clearly see your struggling figure; You seem to be at peace with the world, but I know that you have an enterprising heart that is unwilling to lag behind and dares to compete first. You always study hard and work hard in obscurity. Don't be discouraged even if you encounter difficulties and setbacks. You are stubborn in silence and confident in simplicity.
7. In the teacher's eyes, you are a lovely girl, you are an ordinary simple girl, you are healthy and energetic, and you are often unknown, but when talking to you, you can talk to Kan Kan. You usually don't talk much, but you pay attention to the lecture and finish your homework carefully in class, which is often appreciated by your classmates and teachers. I hope you will develop to the depth and breadth of your knowledge, be firm and steady, and meet greater challenges.
8. After a semester's study and life, my thoughts are becoming more and more mature and my psychology tends to be stable. I see hope in you. You can do your duty in all kinds of work. You respect your teachers, love your teachers and are willing to work for them in peacetime. Basically, I can finish the homework assigned by the teacher on time. The results are gradually stable and the ability is also improving. Sometimes you will encounter temporary difficulties in your study, but you must know that there will inevitably be obstacles on the long road of life. I hope to pay more attention to studying law and improve efficiency. I hope you always have a confident smile.
9. You respect teachers, observe discipline, study hard and get along well with your classmates. In my study, I have made great progress through the efforts in the second half of the semester, such as writing and writing, but I still have to catch up. It is a gratifying change that you can correctly recognize your own shortcomings and keep improving. Teacher Zhang believes that as long as you concentrate on your study, be diligent and practical, read widely and try to find a suitable learning method, you will get more and greater gains!
10, students always like to be close to you, always talking and laughing with you, always smiling at any time, as if you have never experienced sadness, your analysis of problems is always unique, and the teacher appreciates your cleverness. It is universally acknowledged that your grades are good, and the teacher also knows that it is inseparable from your efforts. Keep going.
You are quiet, smart and a little shy. You always study hard silently, even if you encounter setbacks, you are not discouraged. You are stubborn in silence, firm and tenacious in simplicity, infecting everyone. You are gentle and humble in appearance, and you have indestructible perseverance in your heart. With your hard work and persistent pursuit, you have made great progress in your study and in all aspects. In fact, I often feel a little distressed when I look at your busy figure, but I know that you are getting closer to your goal step by step. I hope you will continue to work hard, become an outstanding talent in society in the future and realize your beautiful ideal.
12, a semester of study, life, mature thinking, psychological stability, I see hope in you. I am glad to see that you have made progress in the past semester. You have strong adaptability and adaptability, are good at adjusting your knowledge structure, study hard and perform well. I hope to make greater progress.
13, I have been in high school for two years, and the situation in the first semester is not very clear, but this year and a half, more than 500 days and nights, you are so conscientious every day, silently insisting on your own ideals, and this spirit will definitely become the most beautiful scenery in your life. For the study of science, we should know more, think more and summarize the methods of learning and doing problems. The study of liberal arts needs more accumulation and sureness, while the study of science depends more on the ability of understanding and thinking. In senior three, we work hard not only for time and perseverance, but also for wisdom and methods.
14, "Behavior forms habit, habit forms character, and character determines fate". Don't underestimate your every little behavior, it often determines the fate of your life. Innocent and simple, you are always doing your own thing silently. You rarely hear your cheerful laughter between classes and see your lively figure in class. You are down-to-earth and meticulous, and your academic performance is often a blockbuster, which attracts everyone to sit up and take notice. You can always take it calmly. May you always keep the character of the grass, ordinary and simple, full of vitality, and great in the ordinary.
15, you are an honest and sincere girl, obedient and sensible, honest and simple. Teachers and classmates like you very much. You work hard, but your study methods are not the best, so your grades are not ideal. I hope I can explore a set of efficient learning methods suitable for me in my future study life.
16, if life is a tree, then ideal is the root, diligence is the leaf, perseverance is the stem, and success is the fruit. If you can diligently and persistently pursue success under the guidance of your goals, your tree of life will blossom and bear fruit. You have the ability to act independently, don't follow others' advice, and have opinions when things go wrong. Strong adaptability, open mind, rich imagination and wide interests. In the teacher's impression, you look wise.
17, you are a girl with a very rich inner world. In the eyes of teachers, you have always been silent, practical and serious in your studies. In the past semester, your academic performance has been among the best, making teachers and classmates sit up and take notice. But who knows how much effort you have behind this achievement? Diligence is the most precious quality of people, which will benefit you for life and help you succeed!
18, one semester, you study hard as always, take an active part in labor, and do what you should do in obscurity. You gradually reflect the simplicity and diligence of a farmer's child. I'm glad to see your progress this semester. Even in the face of the temptation of other students, you can keep your faith. In the future study, I hope you will continue to maintain the excellent quality of studying hard, and at the same time pay more attention to communicating with your classmates, broaden your horizons, strengthen physical exercise, and strive for all aspects to go hand in hand.
19, you are a lively and cheerful girl. Face life with a smile and treat friends warmly. Teachers can always feel the warmth you bring to a big family. I hope you can be more strict with yourself in your study, adjust your learning methods and let your wisdom shine. After all, time flies and time waits for no one. I'm sure you'll have a brilliant smile then.
20. As the "richest man" in Class 13, you have done a lot for me, and I am very grateful to you. It is not easy for you to have your own unique ideas in your study and life, and to be good at putting them into practice and stick to them. Young people are impulsive and easily influenced by external factors, but you can stick to your own learning methods and attitude towards life, which shows that you are mature and stable. You are always full of enthusiasm for class work. When the class teacher misbehaves, you can show understanding and support, which is good.
2 1, think silently and listen quietly. You are diligent in every step. The teacher has quietly fallen in love with this valuable moral, but the teacher wants to see your sharpness and boldly show your style, and you will find that you can also smile so brightly. 35. You are full of vigor and vitality, have a wide range of hobbies, and strive to win glory for your class. Being a hero in the sports field is your greatest pride. You may envy those students who have excellent grades. You must think they are smart and easy to learn. Actually, they are not. Really smart people study harder than ordinary people, because they know that the accumulation of knowledge lies in diligence, learning is continuous, and silent cultivation will certainly have fruitful results. I hope to pay more attention to studying law and improve efficiency. I hope you always have a bright smile.
22. Teachers appreciate not only your excellent grades, but also your persistent learning spirit. You are always thinking about problems and eager to get more knowledge; You always study hard at your desk, so your grades are excellent. Can complete the task assigned by the school and get unanimous praise from everyone. Do you remember? How many people shouted for you, cheered for you, cheered for you, and the teachers at that time, I was so excited, so excited! Since then, that scene has been deeply branded in my mind. The vast ocean comes from a trickle, and extensive knowledge depends on accumulation. May you constantly temper yourself and strive for greater progress.
23. You are the "Water Blower" in our class. Not only do people call you that, but you are also willing to accept it. You live happily every day. This attitude towards life can not only keep you in a good mood, but also make you smarter in your study and work. I hope you can keep this optimistic style no matter how much pressure you face in the future. The new progress this semester is that the font has become beautiful, which actually illustrates a very simple truth: as long as you make up your mind to do something, you will certainly succeed. Nothing is impossible in the world.
You are a studious student, and you have shown your intelligence in many ways. Diligent, you are steadfast in every step. If you can explore and summarize the rules more actively, arrange the study of all subjects in a balanced way, and develop yourself more comprehensively, I believe you will have better performance.
25. If life is a tree, then ideal is the root, diligence is the leaf, perseverance is the stem, and success is the fruit. You have a good learning attitude and a flexible mind, which laid the foundation for your success. You always study hard silently, even if you encounter setbacks, you are not discouraged. You are stubborn in silence, but you will succeed in simplicity. I always have confidence in you.
26. You are lively and brave, smart and generous, responsive and proactive ... You see, I have told you so many advantages in a series, which shows that you are a pretty good child. You are confident but often anticlimactic, which will only hold you back, so you should learn to restrain yourself and be strict with yourself, and cultivate a style of Excellence both in discipline and in study. Smart boy, actually you have great potential. I believe you will foster strengths and avoid weaknesses, learn to analyze and think, and keep company with good books. May your development space be more open!
27. You always study hard in obscurity and do your work conscientiously and practically. Don't be discouraged even if you encounter difficulties and setbacks. You are stubborn in silence and confident in simplicity. Every time I open my homework, I can feel your persistence. However, it may be a matter of method. You find it a little hard to study. I believe that after the adjustment of the holiday, you can find a scientific method that suits you, regroup and sprint to the ideal future in the best state.
28. You are gentle and don't talk much, but you are sincere, polite, enterprising and have the ability to distinguish right from wrong. Responsible for class eye exercises, serious and responsible, and harmonious relationship with classmates. The homework assigned by the teacher must be done carefully. Reading extracurricular books extensively will definitely add luster to your life. May you pay more attention to the study and training of basic knowledge, strengthen the cultivation of ability and be a good student with all-round development!
29. As a lively and individual child, you often have a profound and unique understanding of problems. You have a wide range of interests, and you won the first place in the class shuttlecock competition, which impressed everyone. In fact, you still have a lot of potential to play. At ordinary times, you often appear careless and careless, which will only hinder your progress. Teacher Zhang believes that as long as you concentrate on your studies and "keep your feet on the ground and persevere", you will certainly achieve remarkable results!
30. Although I am unknown on weekdays, I am always in class activities. You can always find the true meaning of life in the details of life. Have excellent thinking quality and ability, study extremely hard and get excellent grades. May you always have a confident smile.
