Summary of ninth grade chemistry teaching 1
This semester, I served as the chemistry teacher of Class 5-8 in Senior Three, the leader of chemistry lesson preparation in Senior Three, and served as the guidance of the new teacher, Teacher Yang. Through a semester of hard work and struggle, we have achieved good results in all aspects.
First, the quality of classroom education and teaching has improved significantly.
This semester, guided by activation, optimization and individualization, I seriously studied teaching materials and methods, mastered the basic knowledge and skills of textbooks, attached importance to the process of acquiring knowledge and the cultivation of scientific inquiry ability, closely linked with the reality of social life, grasped the application of knowledge, deepened classroom teaching reform, strengthened mutual learning and discussion in the teaching process, cultivated students' interest in learning chemistry, and realized the scientific charm and value of chemistry.
Two, presided over the teaching and scientific research work, and achieved remarkable results.
This semester, I served as the head of chemistry lesson preparation for senior three. I led the whole group of teachers to seriously carry out teaching research, make excellent courseware, share resources, discuss a number of teaching and research topics together, and complete a series of teaching and research work according to the requirements of the school, with remarkable results.
Thirdly, the subject infiltration in teaching.
According to the subject characteristics of chemistry in the third grade, I constantly infiltrated the concept of environmental protection and dialectical materialism in teaching, so that students can realize the root of environmental pollution and the measures and methods of environmental protection.
Fourth, the performance of cultivating outstanding and secondary students is obvious.
In view of the poor foundation of students in our school, I try my best to face all students in classroom teaching so that most students can understand and do classroom exercises. At the same time, I teach students in accordance with their aptitude, strengthen the guidance of learning methods, guide students with good original knowledge base and strong learning ability to develop their knowledge vertically and horizontally, focus on guiding underachievers with poor original knowledge base and weak learning confidence to form good habits, and make full use of the evening self-study time for targeted individual counseling.
Verb (abbreviation for verb) develops active interest groups.
At the beginning of the semester, each class selected 3-5 students to form a chemistry interest group, and carried out meaningful chemistry experiment activities once a week as planned, which greatly mobilized students' chemistry interest, broadened students' chemistry horizons and enlivened students' extracurricular knowledge. And organize out of the school to investigate the production process of tap water, collect and explore metals and metal minerals, explore local fuel and combustion conditions, so that students can better master chemical research methods in combination with practice.
In a word, I have been trying to finish the heavy teaching work this semester, and at the same time I have been constantly reflecting on my own experience and shortcomings, with a view to by going up one flight of stairs in my future work!
Summary of ninth grade chemistry teaching II
This year, I teach chemistry in Class Two and Class Three, Grade Three. Chemistry is a new subject in grade three, the initial stage for students to enter the hall of chemical science, and also a compulsory subject for senior high school entrance examination. Just one year's teaching not only requires students to master the basic knowledge and skills of chemistry, but also guides students to have interest and atmosphere in exploring chemical science in the future, which also directly affects students' further studies. Chemistry is a new subject, which has its advantages and disadvantages. Chemistry is offered in grade three because students are required to have a certain knowledge base and learning ability, and good guidance can get twice the result with half the effort. Once students have a weak learning foundation, or are passive in learning, or are afraid of difficulties, they will face great difficulties.
Today's students, due to such social, family and self factors, generally have a low learning mood and a certain degree of fear of difficulties and dependence. Facing the arrangement of three class hours a week, our teaching task is quite heavy. In order to better complete the teaching tasks of this semester, we make and effectively adjust according to the actual situation in teaching. The work of this semester is summarized as follows.
First, stimulate students' interest in learning chemistry.
This year, our school implements the happy teaching method, grouping students, giving full play to students' main role, mobilizing students' enthusiasm, really making students move in the classroom, and the classroom is alive, with good results. Educational psychology points out: "The important components of students' learning motivation are mainly students' learning consciousness and direct interest in learning." In teaching practice, I attach great importance to the introduction of each lesson, and introduce new lessons from reviewing old lessons to make the old and new knowledge connect well; Attach importance to the implementation of the new curriculum concept, so that students can acquire knowledge through inquiry. For example, when teaching the law of conservation of mass, I designed and implemented the following teaching links:
[Question] What changes have taken place in the quality of substances during chemical changes?
[conjecture or hypothesis]
[Design and carry out the experiment-P96 experiment-P96.
[Conclusion] 1. The total mass of a substance remains constant in chemical changes.
2. When designing an experiment to explore "What happened to the quality of substances in chemical changes",
If the device is on, no gas can participate or react.
If gas is involved or generated in the selected reaction, the device must be sealed.
[Exercise] 1, the following statement conforms to the "quality law" is ()
(1) 1g red phosphorus is burned in 2g oxygen to generate 3g phosphorus pentoxide.
(2) The total mass of hydrogen and oxygen obtained by complete electrolysis of 10g water is still10g.
(3) The increased mass of magnesium bars after combustion is equal to the mass of oxygen participating in the reaction.
(4) 10g water is still 10g water vapor after complete vaporization.
(5) The mixed mass of100g alcohol and100g water is 200g.
1. Explain the "law of mass" from the point of view of particles.
【 Summarize the "five invariants" and "two inevitable changes" in chemical changes.
In the teaching practice, I insist on facing the whole class, teaching according to the book, trying to make students understand, insisting on not talking about difficult problems and digressions for most students, and focusing on basic knowledge.
Second, play the role of chemical experiments
Chemistry has its own advantages-chemical experiments can arouse students' interest. In classroom teaching, I carefully organize experimental teaching. In demonstration experiments, I guide students to learn to observe experimental phenomena, learn to observe and think in experiments, and guide students to understand the essence of phenomena and substances and their changing laws. According to the content of the textbook, organize students to carry out relevant experimental inquiry, so that students can stimulate their interest in chemistry learning, enhance their feelings for science, understand the nature of science, and initially form a certain scientific inquiry ability through experimental study of scientific inquiry methods.
Summary of ninth grade chemistry teaching 3
This semester, I worked as a chemistry teacher in Class (1)(2)(3) of Grade Three, and as a class teacher in Class (1) of Grade Three. The education and teaching work of this semester is summarized as follows:
Looking at the past semester, I have been very diligent and hardworking since the first semester, and my teaching work has also made great progress this semester, and all the students I have taught have made great progress. There has been a breakthrough in grasping students' thoughts and teaching methods, and the teaching results have successfully completed the goals set at the beginning of the semester, which can be said to be fruitful.
First, the breakthrough in teaching methods
According to the idea of hierarchical teaching, I took the following measures before, during and after class, which greatly improved the teaching efficiency.
First of all, do a good job in preparing lessons and set learning goals. Teachers should do a lot of preparatory work in advance and choose the most suitable layered questions, so that students can have a preliminary understanding of the content in our class.
Secondly, in class, we should talk as little as possible and practice more, fully arouse the enthusiasm of students' autonomous learning, so that students at different levels can find themselves in the process of learning, sum up themselves and be guided by teachers. This requires teachers to ask appropriate questions in key places to guide students' thinking, and teachers can summarize and explain key places. Can follow up in time after class, check the students' learning effect, feedback the learning effect in time, and follow up the students who have not finished well in time.
Second, give full play to the advantages of collective lesson preparation
The best place of the goal-layered teaching method is to give full play to the advantages of the lesson preparation group in preparing lessons collectively, and Qi Xin works together to make teachers learn from each other's strong points. It avoids that in the past, everyone had to do a lot of work in individual combat, which consumed teachers' energy excessively, resulting in teachers not having much time to prepare lessons. The introduction of new measures not only exerts the collective strength, but also frees teachers from heavy work. This semester, I can play the role of monitor. In the collective lesson preparation, speak actively and discuss the possible problems in the teaching process. There are many layered exercises, review questions and simulation papers, and there are no reservations about the teaching content.
Third, ideological work is always unremitting.
As the main body of learning, students' learning activities are influenced by family, society and classmates. If students are adversely and negatively affected, then our teaching will be very difficult. A class can't rely entirely on the head teacher to do ideological work. Although I am not a class teacher, I will always pay attention to the students' ideological trends, their classroom performance, whether they concentrate and guide in time, and do a good job in ideological work after class, so as to make students believe in my teaching and improve learning efficiency. Students can speak actively in class, everyone can devote themselves to their studies, and their grades will naturally improve greatly. In the final exam, all the classes I taught were able to successfully complete the tasks assigned by the school.
Fourth, do a good job of psychological counseling before the exam
If the examinee's mastery and application of knowledge is the "hardware" for the success of the exam, then the psychological adjustment before the exam is the "software" for the success of the exam. The closer the exam is, the more obvious the function of the software is. It can be said; Review on weekdays is the foundation and improvisation is the key. Two weeks before the middle school entrance examination, I used the class meeting time to hold class meetings on topics such as "June, let's face it-mental health education before the middle school entrance examination" and "the top ten things to sprint for the middle school entrance examination". Guide students to treat the senior high school entrance examination correctly, overcome some abnormal test mentality and psychological obstacles, and coach students to have good test psychology. The focus is on the technical counseling of pre-test psychology. First of all, we should make full preparations for the exam. First of all, we should be confident. Confidence is half the battle. We should have the courage to overcome difficulties and learn to relax ourselves before the exam. The second is the psychological skills in the examination room, that is, calm method, relaxed method and rhythm (time) control method. Through the theme class meeting, the third grade students have further improved their regulatory role with good examination psychology. This is my summary of this semester.
Summary of ninth grade chemistry teaching work 4
The busy teaching work in senior three has come to an end temporarily. Every day in the third grade, we are thinking ahead. Because of the combination of physics and chemistry, the final result is still unknown, so let's summarize what we have done first.
First of all, talk about experience.
1, willing to toss and turn, not afraid of difficulties
This year, the teaching and research section asked us to basically complete the teaching of two books in the first semester, which I think is a very good practice. This is bound to drive us to think about new methods, without increasing the number of class hours, but adding two units to the teaching content to complete the teaching task efficiently. This year, we should work hard on how to integrate, accurately grasp the goals of the new teaching, and achieve a solid foundation, meticulous and appropriate. Facts have also proved that conformism can only stagnate; If you are willing to toss, you can go further and see more beautiful scenery.
2. Use experiments to attract attention
Chemistry is a science based on experiments. In the eyes of students, this experiment is very interesting. As a teacher, we must protect students' curiosity and make them love chemistry more and more deeply. In addition to in-class experiments, some extra-curricular experiments can be added appropriately. The students are beginners in chemistry. We can reduce the difficulty of experiments, help students find some small chemical experiments in life, encourage them to experiment, stimulate their desire to explore and record the process. From the beginning, students have their own opportunities to explore, and students have gradually entered the track of exploration. A thoughtful teacher will also cultivate a thoughtful student.
3. "Infiltration" and "Willingness"
Experience tells us that we should learn to squat down and look at students and look at problems from their perspective.
We sometimes get angry, but what students do wrong is probably that we have not done enough "infiltration" work, but are eager to achieve "infiltration" effect. Therefore, it is not only an idea, but also a kind of courage and mind to not rush for success and even allow students to be "slow" temporarily.
Inquiry teaching, student-centered, group cooperation ... There are many teaching methods, but we don't recognize them, but we don't take the time to do them. We want to change the concept of class hours, in fact, only by giving up can we get it. Regardless of the new teaching or review stage, we should be willing to thoroughly infiltrate an important knowledge or error-prone knowledge through various means.
4. Do your daily work seriously
Although there are only two people in the preparation group, our collective preparation is unambiguous. We learn from each other's strengths and prepare content and methods. As the saying goes, "One person's wisdom is insufficient, and two people's wisdom is inexhaustible." We always keep our passion in class, and provide students with various opportunities to show, and strive to cultivate students to express their thoughts and ideas loudly and clearly in class; Improve students' participation in thinking and ensure that all students are relaxed in class, and no one is absent-minded or dozing off.
As for homework, fortunately, a large part of our classmates will do chemistry homework first, because our homework will not exceed 20 minutes every night and 40 minutes on weekends. Maybe this is also a way to keep interest. But our homework is definitely the result of careful selection. Before the arrangement, we will do it seriously from the perspective of students. In the process of marking papers, we should pay attention to recording typical students and typical mistakes, and make targeted comments and counseling. Atypical mistakes, in order to save time, sometimes students will write problem-solving analysis next to their wrong questions to help them correct them. Once I become a student, I think students will attach great importance to what teachers leave in their notebooks, even if it is only a few words. In short, students' participation in class and whether their homework is independent and serious are two requirements that I have always attached the most importance to, and I can't relax for a moment.
Second, lack of reflection.
Behind all the meticulous work is the lack of time, even the lack of time. Although we insist on and strongly support self-made teaching plans, the trivial and heavy education and teaching work makes it too late for us to collect good materials extensively. And there are all kinds of symbols and charts in chemistry. Sometimes we have good ideas in our minds, but our computer level is limited, so it is difficult to present them in the final lesson plan. However, I firmly believe that a good beginning is half the battle. Year after year, the quality of our materials will get better and better.
In addition, the content of training and making up the difference is not systematic and needs to be integrated. We should give full play to each student's learning potential, but in the review stage, the' potential' of some excellent students was ignored by us, and there was a situation of' not having enough to eat'. Therefore, you should be a conscientious person at ordinary times and save more corresponding questions to improve your ability; For underachievers, we should also prepare some corresponding materials for them, so as to truly achieve hierarchical teaching and effective teaching, and pay attention to the development of each student. "There is still a long way to go in Xiu Yuan, and I will search for it." I would like to keep a learning heart forever, full of enthusiasm, and make firm progress on the road of chemistry teaching and education.
Summary of ninth grade chemistry teaching 5
This semester, I am engaged in chemistry teaching in the second semester of Grade Three. Chemistry is a new subject in the next semester of Grade Three. It is the primary stage for students to enter the hall of chemical science, and it is also a compulsory subject for the senior high school entrance examination. A short period of one year's teaching not only requires students to master the basic knowledge and skills of chemistry, but also guides students to have interest and atmosphere in exploring chemical science in the future, which also directly affects students' continuing education. Chemistry is a new subject, which has its advantages and disadvantages. Chemistry is set up in the next semester of grade three because students are required to have a certain knowledge base and learning ability, and good guidance can get twice the result with half the effort. Once students have a weak learning foundation, or are passive in learning, or are afraid of difficulties, they will face great difficulties.
Because students have social, family and self factors of one kind or another, they have a certain degree of fear of difficulties and dependence in their studies; In addition, because there is no tutoring time such as evening classes, our teaching task is quite heavy in the face of the arrangement of four classes a week. In order to better complete the teaching tasks of this semester, we have made and effectively adjusted according to the actual situation in teaching. The work of this semester is summarized as follows.
First, stimulate students' interest in learning chemistry.
Educational psychology points out: "The important components of students' learning motivation are mainly students' learning consciousness and direct interest in learning." In teaching practice, I attach great importance to the introduction of each lesson, and introduce new lessons from reviewing old lessons to make the old and new knowledge connect well; Attach importance to the implementation of the new curriculum concept, so that students can acquire knowledge through inquiry. For example, when teaching the law of conservation of mass, I designed and implemented the following teaching links:
[Question] What changes have taken place in the quality of substances during chemical changes?
[guess or hypothesis]
[Design and Experiment] Experiment 1 P96 Experiment 2 P96
[Conclusion] In the process of chemical change, the total mass of substances remains unchanged.
In the teaching practice, I insist on facing the whole class, teaching according to the book, trying to make students understand, insisting on not talking about difficult problems and digressions for most students, and focusing on basic knowledge.
Second, play the role of chemical experiments
Chemistry has its own advantages-chemical experiments can make students interested. In classroom teaching, I carefully organize experimental teaching. In demonstration experiments, I guide students to learn to observe experimental phenomena, learn to observe and think in experiments, and guide students to understand the essence of phenomena and substances and their changing laws. According to the content of the textbook, organize students to carry out relevant experimental inquiry, so that students can stimulate their interest in chemistry learning, enhance their feelings for science, understand the nature of science, learn how to use experiments to carry out scientific inquiry, and initially form a certain scientific inquiry ability.
For example, organize students to explore the preparation method and chemical properties of oxygen; Explore the preparation and properties of carbon dioxide, arrange students to pour carbon dioxide into a beaker with two uneven candles, and cover the other beaker to explore the burning of candle flame; Students feel the charm of scientific knowledge in a relaxed and happy atmosphere.
Third, make efforts to review and summarize.
The ninth grade chemistry is a senior high school entrance examination subject. To improve the quality of teaching, on the one hand, students should have solid basic knowledge and skills; On the other hand, students must be more adaptable. Therefore, it is necessary to lay a solid foundation, strive to pass each chapter in teaching, do a good job in reviewing each stage, and try to help students summarize and print the corresponding review summary for the chapters with complex key knowledge and knowledge points; The exercises and questions are strictly screened. In addition, students' homework is basically collected and corrected in time, and personal requirements and opinions are put forward in the homework. For another example, improving the make-up work is a powerful and effective supplement to the normal teaching work. For students who have spare capacity for study, the capacity and difficulty of homework have increased. While adapting to the questions in the senior high school entrance examination, they also came into contact with the competition questions. For students with poor ability to accept, we should be patient and meticulous, never tire of asking questions, and use extracurricular time to give them counseling.
Fourth, the lack and direction of efforts.
In the teaching work, the requirements for students are not strict enough, and there are requirements for students to master knowledge but no effective implementation methods, which leads to students' unconscious disconnection, and their grades will gradually decline from time to time. Due to some practical reasons, there is less time to contact with students and less time and channels to recommend them. In the future teaching, students should be full of confidence and trust from beginning to end, encouraged and flogged.
