Junior high school chemistry final homework summary 1 I am a chemistry teacher in classes 7, 8 and 9 this school year. Now make a summary of my work.
First, actively do a good job in daily teaching.
Actively and conscientiously do a good job of collecting materials for preparing lessons before class, and then prepare lessons collectively. The proportion of each teacher's audio-visual courses is above 90%. Students' homework at least twice a week requires all batches and all corrections. When problems are found, they should be solved in time, commented in class in time and given feedback in time. A good student experiment requires all students to carefully observe and record the experimental phenomena and carefully write the experimental report after class; Each chapter has at least one extracurricular exercise, which requires a certain knowledge coverage, a certain degree of difficulty and depth, and each chapter is assigned by a special person; For the test questions once in each chapter, there are also special people who are responsible for the questions, so as to achieve certain expected results.
Second, actively participate in teaching reform, so that the level of teaching and research will reach a higher level.
This semester, the school has implemented a variety of teaching modes, allowing students to participate in the teaching process, better improving students' interest and enthusiasm in learning, and enabling students to learn more independently and learn learning methods. This semester, I participated in a district-level demonstration open class. Can actively respond to the requirements of school teaching reform, make full use of online resources, use heuristic teaching, fully reflect the student-centered teaching model, and constantly improve their teaching level.
Third, strengthen business study in spare time.
Actively learn all kinds of knowledge to enrich themselves, so as to better educate and teach under the guidance of solid knowledge in work. In order to adapt to the current form of education, charge yourself. I also study in computer school in my spare time at night and weekends. Learn to make multimedia courseware to serve teaching, and at the same time help other comrades to make courseware, find information online and so on.
Fourth, the direction of next semester's efforts
1. Strengthen the training of one's own basic skills, be precise and concise in class, pay attention to the cultivation of students' ability, and strive for a clear class and paragraph in knowledge. Train students to improve and concentrate in various ways.
Pay more attention, love and patience to the poor students, so that they can make greater progress in all aspects.
3. Strengthen discipline education, so that students can not only concentrate on their studies in class, but also restrain themselves in strict accordance with school discipline and class rules after class.
4. Communicate with students in an equal manner, exchange students' trust with sincere heart, and really care about each other, which not only makes students fear you, but also makes them close to you, and sincerely accepts your love and love.
5. Make great efforts in teaching, and strive to make greater progress in class students' abilities and achievements on the original basis.
Education is a continuous, innovative and endless work. The society is developing, the times are advancing, and the characteristics and problems of students are constantly changing. As educators with a sense of responsibility, we must discover, study and solve new situations and problems in the management of students' education in a timely manner with high sensitivity and consciousness, master their characteristics, discover their laws, and do a good job dutifully, so as to complete our sacred historical mission.
Summary of the final assignment of chemistry in the second day of junior high school; engaged in chemistry teaching in four classes of grade 1-4 this school year. Middle school chemistry teaching is the enlightenment and basic stage of chemistry education. It is necessary to lay a foundation not only for students to study related majors, but also for graduates to work and solve some practical problems. Chemistry is offered in grade three because students are required to have a certain knowledge base and learning ability. The problems I face are less class hours and more tasks. A considerable number of students have a weak learning foundation, low learning mood and a certain degree of fear of difficulties and dependence. In order to better complete the teaching tasks of this semester, I made timely and effective adjustments according to the situation in actual teaching. The work of this semester is summarized as follows.
First, stimulate and maintain students' interest in learning chemistry.
When students first came into contact with chemistry, they were very interested in chemistry, especially chemical experiments. However, when we find that learning chemistry requires complicated knowledge, especially when learning chemical terms and basic concepts, we often feel abstract and boring. We often regard chemistry as a "second foreign language", think that chemistry is a very difficult subject, and gradually lose interest in chemistry. For this reason, I have educated students in the history of chemistry, and told some anecdotes about chemists exploring the mysteries of chemistry without fear of difficulties and obstacles. Talking about China's great achievements in ancient times and its backwardness in modern times, and the rise of China also needs chemistry, most students can feel the importance of learning chemistry well.
Junior high school chemistry needs to remember a lot of knowledge, which is complicated and time is tight, so I will tell students the characteristics of chemistry from the first class and remind them to pay attention to some clever memorization methods. In teaching, the main content of each class is condensed into several jingles to help students understand and remember quickly. For example, there are two methods of oxygen production in the laboratory: potassium permanganate oxygen production, solid-solid heating device, drainage method as the first choice for gas collection, and upward vacuum can also be used. The operation steps are seven words, "Check the installation, collect and extinguish the fire at a fixed point".
"Hydrogen peroxide into oxygen, solid-liquid heating device. It is feasible to save energy at room temperature, and the operation is safe and simple: "inspection and acceptance" is only four words. "
For another example, it is difficult for students to understand molecular atoms and ions. I summed it up as "there are three kinds of molecules, molecules, atoms and ions, in which atoms are fundamental and three paths constitute matter." "Metallic elements, solid nonmetallic elements and rare gases are all directly composed of atoms." "Nonmetallic atoms combine first, and there are many kinds of molecules." Most substances have molecular structures: diatomic molecules, non-constituent compounds and non-constituent compounds ... "and so on.
Second, develop and play the role of chemical experiments
The enthusiasm of junior high school students depends on their interests, and their visual memory ability exceeds their abstract memory ability. In teaching, I often use pictures, models and other means for intuitive teaching. 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 exploration. For example, the open class "Exploring the preparation methods and chemical properties of oxygen" opened by our group this semester has a serious and lively atmosphere and achieved good results. Students are usually encouraged to make use of all kinds of materials available in life to carry out small experiments.
Third, be precise and concise, and strive to improve teaching efficiency.
In teaching, I closely follow the requirements of curriculum standards and exam instructions, use the contents of teaching materials, face all students, create situations, set questions and solve problems. In teaching, students are always reminded of the learning rules-"reading" and "practicing", which is the way to consolidate knowledge. Carefully design some targeted questions, guide students to analyze and study these questions, let them practice by hand or orally, and achieve the purpose of mastering knowledge by analogy. For example, after learning that the principle of ironmaking is reduction, I asked my students to write the chemical equations of reducing iron oxide and copper oxide by hydrogen or carbon powder, and then clarify the similarities and differences, so as to further review and consolidate the redox reaction.
Fourth, do a good job in unit review.
The content of junior high school chemistry knowledge is complex, involving dozens of elements and compounds and a large number of chemical equations. Therefore, grasping the internal relations of these knowledge, distinguishing similarities and differences, summing up and comparing, and helping students form a knowledge system are one of the ways to improve their chemistry scores. In teaching, I try to go through each chapter and do a good job in reviewing each stage. Each chapter helps students to summarize and print the corresponding review assignments, so that students can gain something. The exercises and questions are carefully selected, and the quantity and quality are reasonable. Students' homework is basically collected and corrected in time, and personal requirements and opinions are put forward in the homework. Usually, we should pay attention to cultivating excellent students and make up for poor students. For students who have spare capacity for study, we should increase the capacity and difficulty of extracurricular homework, and contact the competition questions while adapting to the test questions. For students with poor acceptance ability, be patient and meticulous, never tire of asking questions, and use extracurricular time to give them counseling.
Verb (abbreviation of verb) deficiency and reflection.
This year, due to the advance of the Spring Festival, students' acceptance ability is unexpected, which makes the later teaching unable to keep up with the progress. There is not enough contact time with students, and there are relatively few time and channels for communication with students. In the future teaching, we should contact and communicate with students more, learn to think from their perspective, and be full of confidence and trust in students. I believe that through the joint efforts of teachers and students, we can achieve better results.
A busy year has passed. During this year, with the guidance and support of school leaders at all levels, I successfully completed various educational and teaching tasks. The work of this school year is summarized as follows:
First, the use of learning plan teaching
In this school year, I seriously studied the teaching theory of "learning plan" and applied it to teaching. Change the teaching concept, take students as the main body, guide students to learn independently, and let students understand the mystery of knowledge through independent learning, thus generating a strong thirst for knowledge. The design of exercise questions should be hierarchical and gradient, and the questions should go from shallow to deep. By improving the ability limit of students at different levels to enhance and consolidate knowledge points, every student will gain something. Write a teaching reflection carefully after each class, find out the shortcomings in teaching, sum up experience and learn lessons, and constantly improve your teaching skills.
Second, improve students' interest in learning chemistry
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. 、
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 collecting and correcting, and personal requirements and opinions are put forward in the homework. For another example, training outstanding students to make up the difference is a powerful and effective supplement to normal teaching. For students who have spare capacity for study, the capacity and difficulty of homework have increased. At the same time, they are exposed to more questions while adapting to the exam 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. In recent years, chemistry test questions involve social hot topics such as environmental protection. In normal teaching, students should have time to read extracurricular scientific and technological knowledge, get in touch with and understand society as much as possible, observe and analyze problems from the perspective of chemistry, and apply what they have learned. Cultivate students' knowledge and ability from different angles.
Fourth, the lack and direction of efforts.
(1) In the teaching work, the requirements for students are not strict enough, and there are requirements for students to master knowledge but there are no effective implementation methods, which leads to unconscious students' disconnection, and their grades will gradually decline. 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.
It is not advisable to lay a solid foundation and catch up with the progress desperately. Grasping basic knowledge means grasping the knowledge of chemistry textbooks and trying to pass every chapter well in teaching. Because of the differences in intelligence and learning foundation among students, students' ability to master chemical knowledge is also different. Teachers should teach students in accordance with their aptitude and try to reduce backwardness. Rushing for success in normal teaching in order to leave more review time will inevitably lead to students' "indigestion" of knowledge, and even make some students who can't keep up with their studies lose interest in chemistry.
⑶ To master basic skills, you should master the skills of using chemical terms and basic experimental skills. In the usual experimental teaching, students should really understand the chemical reaction principle, device principle and operation principle involved in each experiment, give them more opportunities to do experiments, and experience the process and fun of observation and research through experiments, effectively improve their experimental ability and stimulate their interest in learning chemistry.
Summary of the final homework in junior middle school chemistry 4 I. Basic situation:
Speaker: Huang Min, female,1974,65438+born on February 20th, graduated from the School of Chemistry and Chemical Engineering of Southwest Normal University, majoring in chemical education. 1Since July 1998, I have been engaged in education and chemistry teaching in Nanhai No.1 Middle School, with five years' teaching experience and four years' working experience as a class teacher. 1In June, 1999, he obtained the qualification of the second-level chemistry teacher in middle school, and now he teaches in the second grade of senior high school. According to the promotion regulations, he meets the conditions for applying for the first-class chemistry teacher in middle school.
Second, the declaration reason:
1. Having served for five years, I can love the Party's education, adhere to the Four Cardinal Principles, support the Party's line, principles and policies, and have a correct political stance. Abide by discipline and law, care about the collective, unite with colleagues, have decent style, rigorous teaching, high ideological awareness and good teachers' professional ethics. Be able to engage in the teaching of this subject wholeheartedly, strive for perfection, absolutely obey the work arrangements of superiors and school leaders, work hard, be sincere, experience the sublimity of education from work, gain the meaning of life struggle from work, enjoy the pleasure of being a teacher at work, and gradually enrich yourself at work.
2. I have taught chemistry in senior one, senior two and senior three, and I am familiar with junior high school chemistry textbooks and syllabus. Have a full understanding of middle school chemistry textbooks, correctly understand and master the chemistry syllabus and textbooks, and correctly teach the contents and focus on explanations. Be able to implement "double-base" teaching, pay attention to cultivating students' innovative spirit and practical ability in chemistry, be fluent in Mandarin, express accurately, write clearly on the blackboard and be coherent.
3. Since I took my present job, I have tried to explore the artistry of classroom teaching and constantly improve my teaching ability.
I know that if I want to achieve something in teaching, I must first become a popular teacher. As the old saying goes, "Learn from your teacher and believe in his way." First of all, I ask myself to be a role model for students in words and deeds, to love every student, both as a teacher and a friend, to transfer my love for education to students' love for chemical knowledge, and to silence students' exploration of chemical knowledge with my strong and persistent pursuit. Ask yourself to show the teacher's style perfectly on the podium; Every class is required to be lively and fascinating, and the teaching quality is up to standard. Every class should be treated as a high-quality demonstration class.
4. I pay attention to the combination of teaching and research and carry out special teaching and research.
Teaching research is the driving force of teaching progress and the fundamental way to form teaching characteristics. Since taking office, I have insisted on teaching in teaching and research, teaching in exploration and educating people in ideological sublimation. I actively participate in various teaching and research activities of the school, pay close attention to and track the development trends of this discipline, the latest teaching and scientific research achievements and college entrance examination information, master the development trends of education, actively participate in the teaching and research activities of departments, take the initiative to undertake teaching and research topics, introduce new scientific research achievements into teaching, and explore the feasibility and operability of integrating theory with practice in teaching, so that teaching and scientific research can promote each other. For example, seriously study the theory of education and teaching and create a teaching reform method suitable for our school; Explore the application of multimedia audio-visual teaching methods in chemistry teaching; Strengthen the research on the relationship between students' psychological behavior and learning efficiency; Explore ways and measures to improve the art of classroom teaching and enhance students' interest in chemistry learning; Do a good job in the development and implementation of training top students and poor students. I participated in the national teaching and research project "Subjective Teaching Method" in XX, and achieved certain results, greatly improving students' learning enthusiasm and academic performance.
Because I am a young teacher, I have only served as a senior three teacher once, and I have insufficient experience in guiding the college entrance examination, so I attach great importance to studying the college entrance examination. Usually, I carefully study the college entrance examination questions in recent years, actively collect the college entrance examination information, pay close attention to the latest developments of the college entrance examination, and make myself fully capable of entering the third year of high school. Won the second prize of Nanhai Young Teachers' Problem Solving Competition in XX, and achieved good results in many college entrance examination questions and mock exams. Over the past year, I have studied the new field of comprehensive review in senior three, and I have gained a lot. According to my own research experience, I combined the content of the comprehensive course of the college entrance examination in this year's exam review, that is, I integrated the examination review of senior three with the comprehensive course review. Each chapter is divided into two sections: "basic knowledge clearance" and "chemistry and subject synthesis around us" While laying a solid foundation, we should use the comprehensive knowledge related to this chapter to irrigate students, expand their knowledge and make comprehensive preparations for the college entrance examination next year as soon as possible. This teaching method has obvious effect and is very popular with students, which makes them full of confidence in the college entrance examination next year.
While participating in teaching and scientific research, express your own experience and experience in words in time, and write more than one paper every year on average. Among them, the lesson of "Metal Sodium" won the first prize in the evaluation of excellent lessons and papers in Guangdong Province in XX years; The paper "The Application of Subjective Teaching Mode in Middle School Chemistry Classroom" won the second prize in Nanhai City and was included in the collection of essays of Nanhai No.1 Middle School. The thesis "Application of Multimedia in Middle School Chemistry Teaching" won the third prize in Nanhai City.
In order to improve students' experimental skills, besides doing every experiment well, I am also good at experimental reform. I use the methods of talking, discussing and experimenting to guide students to watch, do, think, do experiments and learn new lessons, so that students can truly become the masters of learning, with a deeper impression, a firm memory, vivid learning and full of interest. At the same time, organize and guide students to carry out the second chemistry classroom activities, enrich the content of the activities, and make it an important way to stimulate students' interest in learning. These experimental reforms and the organization of the second classroom also provide me with rich first-hand information for further research on thematic teaching.
In education, I can be a teacher and a role model for students.
I have been a teacher for five years and a class teacher for four years, and I also have some achievements. Our class has been rated as "civilized class" for many times and has been praised and rewarded by the school. My paper "A Preliminary Study of Class Management Mode" was exchanged at the meeting of the head teacher. I also pay attention to infiltrating moral education, dialectical materialism education, patriotism education, love of nature education and environmental protection education in chemistry teaching to stimulate students' self-motivation.
In the construction of class spirit, I can face all students, cultivate students' collectivism spirit and encourage them to create collective honor. I am the head teacher of class 107 from 1998. By cultivating effective class cadres and paying close attention to class spirit, my style of study and class spirit are at the forefront of the grade, and I can be rated as a civilized class every month. Huang was also rated as a "Three Good Students" in Nanhai City. 1999 served as the head teacher of Class 203, and was rated as a civilized demonstration class for many times. Wu Shunzhen was rated as an excellent class cadre in Nanhai City. XX years as the class teacher of class 206, and has been taking the senior high school entrance examination. His class style and style of study are excellent, and he won the first prize in the literary performance competition of the Sports Festival. Chen Jianhui was rated as the "Three Good Students" in Nanhai City.
In the course of class, I also pay attention to the cultivation of excellent students. I didn't give up any poor students. In the process of education and teaching, I pay attention to respecting students' personality, and tap students' non-intellectual factors by talking, writing weekly diaries and encouraging, so that poor students can feel that people are concerned everywhere and everything is concerned, thus mobilizing their enthusiasm and consciousness in learning and gradually mastering knowledge, skills and skills. For example, classmate Huang Songsheng, usually active, likes to make friends, often desertes in class and has poor grades. According to his personality characteristics, I often consciously do his ideological work, clearly point out his shortcomings and learning potential, so that he can not only realize his own shortcomings, but also have the confidence to catch up. In the college entrance examination, he finally got good grades and went to the provincial special line.
6. In order to improve my education and teaching level, I insist on planned and purposeful self-study and further study, and establish the view of "lifelong education".
I have been engaged in education for five years, and have been subscribing to the Century Gardener Project series, such as Chemistry Teaching Reference for Middle Schools, Talking about the Work of Class Teachers, Quality Education Theory, Basic Education Reform, etc., and can be applied to education and teaching in combination with reality. From 1998, I participated in the computer training class organized by the school to adapt to Nanhai Audio-visual Education, and successfully passed the elementary and intermediate computer examinations. Can skillfully use Powerpint, Authorware, Flash, web technology to make courseware and personal homepage. Participated in the lecture on mental health education in Nanhai primary and secondary schools in XX years, and consciously applied psychological principles to the work of class teachers.
Third, the direction of future efforts
Adhere to political study and professional training, participate in teaching and research activities organized by various localities, and improve political and ideological awareness and professional ability; Strengthen teaching and research ability, read more books on education and teaching theory, absorb the essence of them, and strive to raise teaching practice to a theoretical level. Further study computer knowledge, make more high-quality teaching courseware, and improve classroom teaching effect; Summarizing the review experience of college entrance examination and national examination and compiling teaching materials are conducive to their own improvement and help new teachers to become familiar with teaching work as soon as possible. I am determined to continue to work hard, strengthen my self-cultivation, be dedicated, enterprising and hard-working, and make greater contributions to cultivating more and better talents and to the prosperity of the motherland and the nation.
The first semester of the five-year school year is coming to an end. According to the teaching plan and new syllabus, the teaching tasks were completed as scheduled this semester. The first to sixth chapters and the experimental part have been completed this semester, and the final review is going smoothly. Do an organized, planned and step-by-step guided study and review, and do a good job of checking and filling gaps. Whether it is the preparation of the teacher's outline or the intensive class in the classroom, the tacit cooperation between teachers and students is reflected everywhere. In the past semester, I noticed the following problems in my teaching. My current work is summarized as follows:
First, pay attention to the teaching of basic concepts.
Teaching the basic concepts of chemistry is very important for students to learn chemistry well. In teaching, I not only pay attention to the scientific nature of concepts, but also pay attention to the stage of concept formation. Because the concept is gradually developing, we should pay special attention to the principle of persuasion, from the shallow to the deep. For some concepts, we can't completely reveal their meanings at once, nor should we absolutize some preliminary concepts. Try to be easy to understand in teaching. Through the analysis, comparison, abstraction and generalization of experimental phenomena and facts, the main points are formed, and students are guided to apply the concepts they have learned to their study, life and labor, so as to deepen their understanding of the concepts and improve their ability to use chemical knowledge.
Second, strengthen the teaching of chemical terms
Element symbols, chemical formulas, chemical equations, etc. It is a chemical term used to express the composition and change of substances, and it is a key tool for learning chemistry. In teaching, I ask students to combine physical objects and chemical reactions, learn the corresponding chemical terms, and connect the corresponding physical objects and chemical experiments with chemical terms. This will help students remember and deepen their understanding of the meaning of chemical terms. We should also pay attention to the decentralized teaching of chemical terms, and let students gradually master the importance of learning chemistry through lively and interesting learning activities and planned exercises.
Third, pay attention to the teaching of knowledge of elemental compounds.
The knowledge of elemental compounds is very important for students to lay a good foundation for chemistry learning. In order to make students learn the knowledge of elemental compounds well, we should pay attention to close contact with practice, strengthen intuitive teaching and experimental teaching, let students contact with physical objects more, do more experiments and increase their perceptual knowledge. Various ways should be taken to help them remember the important knowledge of elemental compounds on the basis of understanding. After students have gradually mastered certain knowledge of elements, teachers should pay attention to guiding students to understand the internal relationship between knowledge of element compounds, let students understand the relationship between the properties, preparation methods and uses of element compounds, and pay attention to strengthening the guiding role of basic concepts and principles of chemistry in learning knowledge of element compounds.
Fourth, strengthen experimental teaching.
Chemistry is a subject based on experiments. Experimental teaching can stimulate students' interest in learning chemistry, help them to form concepts, acquire knowledge and skills, cultivate their observation and experimental ability, and also help to cultivate a realistic and serious scientific attitude and scientific learning methods. Therefore, strengthening experimental teaching is an important link to improve the quality of chemistry teaching. Try to do well in every chemical experiment class in teaching. In my teaching, the preparation before class is very sufficient, and the demonstration experiment phenomenon is very obvious and the effect is good, so that the whole class can see it clearly; Teachers should demonstrate to students from a scientific attitude and standardized operation, inspire and guide students to rise from vivid perceptual knowledge to abstract thinking.
According to the experimental equipment conditions of our school, I changed some demonstration experiments into experiments while talking, or changed some experiments, or made some selected experiments appropriately. At the same time, encourage and guide students to do some small family experiments, and further stimulate students' enthusiasm and inquiry spirit in learning chemistry. I also strictly ask students to guide them to carry out the experimental operation correctly step by step and draw the correct conclusion.
