Sharing work experience in high school chemistry teaching

Introduction: Share your experience in high school chemistry teaching? Due to the "Five Stricts" regulations, teaching time has been greatly shortened, and it is urgent to implement the teaching model of independent learning. Teachers must further update their teaching concepts and change classroom teaching methods and students' learning methods. Good materials are materials that are close to the students' actual situation. I chose to use the above-mentioned materials, which saved me a lot of energy in the review and achieved twice the result with half the effort. Sharing experience in high school chemistry teaching

1. In terms of lesson preparation, I pay attention to the sense of unity and give full play to the strength of the collective.

With the rapid changes in today's society, students' teaching materials are also constantly updated year after year, especially in our chemistry discipline. We must look at our students and our teaching from a developmental perspective. For the better development of our school in the future growth process, for the better development of our students, and for our own better development in teaching in the future. To do all this well, it is not enough to rely on the strength of one teacher alone. I must pool everyone's strength and collective wisdom.

Throughout the entire senior year work, I personally think that what our chemistry group has done better is to review and summarize the deficiencies in teaching last week, and summarize students’ error-prone questions. Through these The information provides a set of error-prone redo questions, allowing students to redo the wrong questions and make the mistakes happen again.

2. In the process of preparing lessons, study the examination syllabus and test questions as the mainstream. Classify the college entrance examination questions in the past five years and do them several times. I will not go into details about this.

3. During the classroom teaching process, I carefully do every detail. In addition, I pay attention to layered teaching and individual tutoring for different students.

How do I teach in the classroom? In order to better attract students' attention and achieve better teaching purposes, I spend a lot of time preparing lessons for each lesson, especially the introduction of new lessons. For example:

When I was talking about chlorine, I designed a question for the students in advance

There was a teacher in the office who liked to raise goldfish. She was very diligent and often changed tap water for the little goldfish. As a result, all the little goldfish died in a few days. Can the students help the teacher investigate the cause of death of the goldfish? What substance in the tap water caused the little goldfish to suffocate? As a result, the students are full of interest in learning the new lesson

When talking about the corrosion and protection of primary battery metals, I used a short story to introduce it

? A short-lived yacht. A wealthy man who likes to follow fashion decided to build a luxurious and luxurious sea yacht. The shipbuilders spent a lot of money to cover the bottom of the ship with the most expensive, beautiful and nickel-copper alloy that is highly resistant to corrosion in seawater. Since the mechanical strength of this nickel-copper alloy was not high enough, shipbuilders had to use special steel to make many parts of the yacht. Amidst the praise, the yacht slowly launched into the water and swam in the waves of the blue sea. However, within a few days, the bottom of the yacht was riddled with white holes and ended its life prematurely. Do you know why this is?

When I talked about metallic sodium, I did a magic trick for the students in class: water to light an alcohol lamp means using water to light the alcohol lamp. The students opened their eyes in surprise. With their eyes wide open, they all broke the casserole to ask what happened. In fact, the reason was very simple. Metal sodium reacted with water to release a large amount of heat, which caused the alcohol lamp to ignite. At the same time, we also pay attention to the intersection between disciplines during lectures to improve students' overall quality.

4. The management of students must be strict but loving

I have very strict requirements for students in terms of learning. For example, I require students to complete homework on time and independently. In addition, on the basis of completing the homework, I also require students to complete the homework in the format I require. Such homework looks very neat. After a period of time, I found that the students' papers have So much better.

During the teaching process, I asked students to finish things today and not leave them for tomorrow. Gradually, students got rid of the habit of procrastination.

Try to care more about students in life. Once, a student asked me for leave during lunch break. I asked him what he was going to do. He said that his belt was broken and he wanted to go out to buy a belt. I thought that if I didn’t take a lunch break, I wouldn’t have the energy to listen to the class in the afternoon. I also thought that I still had a spare belt at home, so I said to the students: Don’t ask for leave. You still have to take a lunch break at noon. I still have a spare belt at home. You first Just wait until you get back from the big break before returning it to me. ?The student readily agreed and ran away happily. Just from such a small thing, he became more active in studying than before, and his relationship with me became more harmonious.

Now let me briefly talk about some of the situations I am currently taking care of in the first year of high school. I have put a lot of thought into preparing for the new students’ report on August 14th, because on the first day, parents’ impressions of the school and their impressions of the class teacher The impression is crucial. For the preparations for the first day, I started from the following aspects:

1. When I got the list of Class 4, I spent nearly an hour researching the names of the students. , home address and other information, because I want to know them as quickly as possible and in the shortest time, which will be beneficial to future management.

2. On the night of August 13th, my partner and I cleaned the classroom cleanly and arranged it neatly to give the students a brand new feeling.

3. Use the blackboard culture to stimulate students' will. I want to use the blackboard to leave a deeper impression on the students. What can I write to stimulate students' desire to learn more? If I just write a welcome I think the new classmates are too vulgar and nothing new. I racked my brains and thought about the final decision. First, let me objectify a few students who symbolized prosperity with sunflowers. I wrote a paragraph next to it. The same dream brought us into the same classroom from different places. For this Dreams allow us to set sail. After all the twists and turns, we will definitely return to the palace of success? This sentence was mentioned in the first day of high-tech written by the students on the first day, which greatly encouraged them. Sharing experience in high school chemistry teaching

1. Actively do a good job in daily teaching work

Actively and conscientiously collect lesson preparation materials before class, and then prepare lessons collectively. Each teacher’s audio-visual teaching ratio is above 90%. Student assignments at least twice a week are required to be revised in full, problems found to be solved in a timely manner, and commented on in class in a timely manner, and feedback is provided in a timely manner; for serious student experiments, all students are required to carefully observe and record the experimental phenomena, and carefully observe and record the experimental phenomena after class. Write an experiment report; at least one extracurricular exercise question for each chapter, which requires a certain knowledge coverage, difficulty and depth. A dedicated person is responsible for setting the questions for each chapter; a dedicated person is responsible for setting the test questions for each chapter. , and to achieve certain expected results.

2. Actively participate in teaching reform work to advance the level of teaching and research to a higher level

The school has implemented a variety of teaching models this semester to allow students to participate in the teaching process Come, better improve their interest in learning and enthusiasm for learning, enable them to learn more autonomously and learn how to learn. This semester I took a district-level demonstration open class. They can all actively respond to the requirements of school teaching reform, make full use of online resources, use heuristic teaching, fully embody the student-centered teaching model, and continuously improve their teaching level.

3. Strengthen business learning in spare time

Actively learn all kinds of knowledge to enrich yourself so that you can use solid knowledge as a guide at work to better educate and teach. Recharge yourself in a form that adapts to the current education. I also use my spare time in the evenings and weekends to study at computer schools. Learn to make multimedia courseware to serve teaching, and also help other comrades to make courseware, search for information online, etc.

4. Directions for efforts in the next semester

1. Strengthen the training of one's own basic skills, teach concisely and concisely in class, focus on the cultivation of students' abilities, and strive to gain knowledge in every class Qing, Duan Duanqing.

Use various methods to train students to improve and concentrate.

2. Pay more attention to poor students, have more love, and be more patient, so that they can make greater progress in all aspects.

3. Strengthen discipline education so that students not only concentrate on learning in class, but also strictly restrain themselves according to school discipline and class rules after class.

4. Communicate with students with an equal attitude, exchange students' trust with a sincere heart, truly empathize with students, not only let students fear you but also get close to you, accept you and love you from the bottom of their hearts. I love you.

5. Work hard on teaching and strive to make greater progress in the abilities and achievements of students in the class on the original basis.

Educational work is a job that is always new and never-ending. Society is developing, times are advancing, and the characteristics and problems of students are constantly changing. As responsible educators, we must use a high degree of sensitivity and consciousness to promptly discover, research and solve new situations and new problems in student education and management, master their characteristics, discover their laws, and do our best to do our best. Good work to fulfill the sacred historical mission we shoulder. Sharing experience in chemistry teaching for senior high school students

1. Research information and find the right direction

How to start a general review of chemistry, what are the purposes and tasks of the review? This is a student who has just entered the senior year of high school The first problem faced is also a problem that teachers must solve when facing the new college entrance examination. Therefore, it is necessary to study some information, understand the potential guiding role, identify the review direction, and lay the foundation for completing the review task.

1. Study the college entrance examination chemistry test questions. Looking at the chemistry test questions of the college entrance examination every year, we can find that one of its outstanding characteristics is its continuity and stability, and it always maintains the principle of stability while changing. As long as we focus on the college entrance examination questions in Ningxia in recent years based on the curriculum reforms in Ningxia and other colleges and universities in recent years, we can find some of the same characteristics, such as the structure of the test papers, types of questions, examination methods and ability requirements. Wait, so as to clarify the review ideas and formulate corresponding review plans.

2. Pay attention to changes in new textbooks and new curriculum standards. Compared with the previous textbooks and curriculum standards, the new version of the textbooks and curriculum standards used now has undergone great changes, such as the adjustment of the content, the increase in the proportion of experiments, the penetration of scientific ideas and scientific methods into the knowledge transfer process, and the increase of Research-based learning content and reading materials such as new technologies and chemical history. Obviously, these changes have been reflected in the college entrance examination propositions. Being familiar with these changes in the new textbooks and new curriculum standards will help to grasp the direction and depth of review, and will help enhance the purpose of review.

3. Be familiar with the exam instructions. The examination instructions (i.e., the syllabus) are the basis for the college entrance examination and the "general outline" of the chemistry review. You must not only read them, but also study them in depth to clarify the proposition guiding ideology, examination content, test question types, depth and proportion, and test ability of the college entrance examination. Level requirements, etc. Not only that, you should continue to read throughout the review process to further enhance your purpose and adjust the direction of review at any time.

2. Strengthen "double base", build "network", and highlight the teaching of main knowledge

Core knowledge: The test content in the examination syllabus requires knowledge at the understanding (mastery) level . The core knowledge of chemistry listed in the "Exam Syllabus" accounts for 39.8%, of which basic concepts and basic theories account for 21.2%, elements of common elements and their important compounds account for 6.8%, basic organic chemistry accounts for 3.4%, chemical experiments account for 2.5%, and chemical calculations account for 5.9%. Since 2005, chemical calculations have not become a separate topic. Instead, they have been integrated into inorganic, organic, and experimental subjects, and tend to be diluted.

No matter how the college entrance examination is revised, "double base" is very important. Strengthening "double-based" teaching is a topic we must emphasize every year after the college entrance examination, and it cannot be overemphasized. Judging from the 2008 college entrance examination science and comprehensive chemistry test questions, the main reason why most candidates lost points was not the difficulty of the test questions, but the shortcomings in the subject "double base".

This enlightens us that when reviewing and preparing for the college entrance examination, we must lower the focus, strengthen the review of basic knowledge and basic skills, and not blindly pursue the "hot spots" of the exam. Therefore, when reviewing and preparing for exams, we should pay attention to the basic and comprehensive nature of students' knowledge, and put the implementation of "double basics" first. First of all, students must be carefully guided to read the textbook, and implement each knowledge point one by one according to the requirements of the exam instructions, leaving no blind spots and reviewing in an all-round way. At the same time, we should pay attention to the "changing points" in the exam instructions every year. These "changing points" are generally reflected in the college entrance examination. Secondly, after students understand the textbook knowledge, teachers should promptly guide students to pay attention to the connections between knowledge points, and connect basic concepts, basic theories, element compounds, organic matter, chemical experiments and other knowledge through points, lines and surfaces respectively to form knowledge. The network systematizes, organizes and networks scattered knowledge. However, it should be noted that the summary of knowledge is not limited to a certain chapter. Relevant knowledge from the entire middle school stage must be integrated into it to form a reasonable knowledge structure.

3. Pay close attention to the three rounds of review, consolidate basic knowledge, and improve comprehensive application capabilities

Laying a solid foundation and implementing the foundation is the primary task of the first round of review. Before entering the first round of review, students forget most of the knowledge they have learned, and this round also takes the most time, about six months.

The first round: lay a solid foundation and systematically build a chemical knowledge structure.

Task: Focus on the textbook and conduct a systematic unit review according to the structural system of the textbook. Not only should students read the textbooks carefully, master the layout system of the textbooks, clarify the context of knowledge, and be familiar with the footholds of knowledge, but they should also be diligent in using their brains and hands-on practice to do various types of exercises.

Measures: Return to textbooks, highlight knowledge integration, connection, and activities, and adopt four links: checking, teaching, practicing, and testing. Complete: meticulous and complete knowledge coverage. Lian: Strengthen the connection between knowledge and connect scattered and fragmented knowledge. Activity: Special topic training, flexible thinking, and flexible application. Check: Check the mastery of basic knowledge in textbooks and understand the academic situation. Teachers should be aware of students' weaknesses. Enhance the pertinence of lectures, exercises and examinations. Lecture: summarize and organize the knowledge points to regularize the knowledge; practice: complete each topic with an appropriate number of exercises; test: analyze and comment on the test paper in a timely manner after each test, point out existing problems, and do a good job Error statistics; teachers self-reflect, review, diagnose, and summarize shortcomings in teaching, and adjust review plans and review methods in a timely manner.

The second round: Cultivate comprehensive abilities and improve comprehensive quality in chemistry.

Task: The focus is on systematization, organization, structuring and networking of knowledge. That is to connect scattered knowledge points into lines and form a network. Cultivate and improve students' comprehensive ability, transfer ability, application ability, inquiry ability and innovation ability of chemical knowledge. It is also an important stage for checking for leaks and filling them.

Measures: segmented summarization, special lectures, and intensive training. The focus is on mastering methods and techniques for analysis and problem solving

The third round: comprehensive training to improve practical capabilities. Comprehensively prepare for the exam in terms of knowledge, ability, and psychology, and improve students' adaptability to the college entrance examination and test-taking ability.

4. Pay close attention to implementation and seek quality from standardized training

Students’ test-taking abilities must ultimately be reflected on the paper. On the paper, whether they can’t do something or can do it correctly, they can’t do it in time. Knowing how to do something well and doing it slowly are equivalent. Therefore, some people have suggested that the secret to success in the college entrance examination is: getting the questions right. This view is very reasonable. How can we do it? Get the questions right? These can be better solved through standardized training and standardized evaluation.

1. To regulate students’ learning behavior, we must first regulate teachers’ teaching behavior. From language expression to the writing of chemical terms, teachers must practice it and set an example. We should pay attention to the subtle influence of our own words and deeds on students.

2. It is necessary to create an atmosphere of standardized training and integrate standardized education into regular training.

Slogans such as "It's better to do one question clearly than to do ten questions in a daze" are put forward to warn students at all times.

3. Provide students with standardized training on problem-solving speed and accuracy within a limited time limit. Later review, there is a lot of training, but more regular training is required. The form can be eclectic, it can be a whole set of simulations, or it can be a special topic training on a certain type of question. The time can be one hour, one class hour, or 10 minutes, 20 minutes, 30 minutes, etc.

4. Create conditions to allow students to fully expose their thinking processes, target the students’ thinking deficiencies, prescribe appropriate medicines, clarify the causes of mistakes, and supplement them with tracking and compensation training to achieve standardized training in error correction.
