Summary of Chemistry Teaching in Grade Three 1
Chemical experiment teaching is an important medium and means for students to acquire and test chemical knowledge in chemistry teaching. It can provide perceptual knowledge materials for students to form basic chemical concepts and basic chemical theories, and can stimulate students' interest in learning. Therefore, chemistry experiment teaching is an important part of chemistry teaching and plays a very important role in the whole chemistry teaching. The experimental teaching research is summarized as follows:
First, it stimulates students' interest in learning chemistry, and students' initiative and enthusiasm in learning chemistry are constantly improving.
Chemistry teaching in junior high school is the primary stage of chemistry education. Junior high school students are curious, and the motivation of learning chemistry is often to satisfy curiosity and interest. The primary task of chemistry experiment teaching is how to stimulate students' interest in learning chemistry, and make this "short-lived" interest develop steadily, so as to improve students' initiative and enthusiasm in learning chemistry. I mainly pay attention to the following links in teaching:
1. Try to start students' experiments.
According to the teaching progress, we try our best to start students' experiments. During this period, 35 demonstration experiments, 9 inquiry experiments and 3 experimental activities were completed. Students should do experiments in groups of two, and each experiment should be registered, and each experiment should be graded from the aspects of classroom discipline, operating norms, and sorting out instruments. After one semester, the teaching effect is good, which completely changes the chaotic teaching scene in the previous experimental class and students form good experimental habits. For some simple demonstration experiments, we should change them to student experiments according to the conditions, so that students can actively acquire knowledge and stimulate their interest in learning.
2. Strengthen the demonstration experiment teaching
Demonstration experiments in classroom teaching can best mobilize students' emotions and stimulate their interest in learning and thirst for knowledge. To this end, we have carefully completed every demonstration experiment stipulated in the outline, and strived to achieve standardized demonstration operation, obvious experimental phenomena, accurate and concise analysis and expression. Some demonstration experimental devices or experimental operations have been supplemented and improved to enhance the experimental effect. Sometimes, according to the needs of teaching materials, some demonstration experiments that are not available in books are supplemented appropriately.
3. Carry out small family experiments
According to the teaching content, students are arranged with some small family experiments closely related to their chemical knowledge every holiday, and students can find materials at home and finish them independently. Students are required to record the observed phenomena, conclusions and knowledge in detail, and communicate in class after returning to school. Most students can meet the requirements put forward by the teacher. The development of family experiments not only enriches students' after-school life, broadens students' horizons, and cultivates students' hands-on experimental ability and observation and analysis ability, but also promotes the understanding and consolidation of knowledge because of synchronization with classroom teaching content.
4. According to the actual situation of the school and students, students are required to carry out extracurricular experiments.
Secondly, guiding scientific learning methods, developing good experimental habits and cultivating students' ability and innovative spirit are important measures to cultivate students' scientific attitude. Good experimental habits should include: using instruments correctly, standardizing experimental operations, carefully observing and recording experimental phenomena, completing experimental reports truthfully, observing laboratory rules, and paying attention to saving drugs and experimental safety. In teaching, we should show students' scientific attitude and standardized operation, put forward strict requirements for students to abide by laboratory rules, and give specific guidance on how to observe, record and experiment phenomena and fill in experimental reports. When filling in the experimental report, I ask students to truthfully fill in all the phenomena observed in the experiment and make corresponding explanations for the phenomena, so as to cultivate students' scientific attitude of seeking truth from facts.
Through a period of practice, chemical experiments make students interested in learning chemistry, make them have fun in learning by doing, learning by doing, and make students' various abilities and qualities gradually form in active and lively learning life again and again. Lay a solid foundation for the study of chemical knowledge.
Summary of Chemistry Teaching in Senior Three (II)
This semester, under the guidance of the superior teaching and research section and the leadership of the ninth grade chemistry teaching and research group, with the joint efforts of all members, all the work of the ninth grade chemistry teaching and research group was successfully completed.
First, know the general situation and obey the arrangement of the school.
In the usual education and teaching work, members of the chemistry group know the general situation, take care of the overall situation, obey the school's division of labor, and bravely shoulder heavy burdens. The members of this group include leaders engaged in grade management and assistants engaged in student discipline management. In the class teacher, everyone works hard and takes the lead in the grade group.
Second, make plans and work in an orderly manner.
At the beginning of school, after discussion by all members, a feasible teaching and research group scheme was formulated, which was in line with the actual situation of our school. In the plan, the monthly progress, weekly progress, questioners of training questions in each chapter and questioners of unit test questions are specified, which are put in place in the teaching work, and the teaching plan is formulated, and the speaker and teaching content are specified.
Third, pay attention to teaching research and improve teaching level.
Every week, members of the same group give lectures on the teaching content of this week, and express their opinions to form * * * knowledge, so as to achieve unified grade progress, unified training, timely feedback and timely error correction.
Attend and evaluate courses as planned. During this period, each teacher has no less than 20 classes and the grade leader has more than 40 classes. The classes involved include new classes, review classes and inquiry classes. The members of this group have benefited a lot from the new curriculum reform.
Insist on bringing the old with the new, improve the professional level of young teachers, spare no effort to provide support and help for young teachers, and help them improve their understanding in subject knowledge, syllabus requirements, teaching materials processing, teaching methods, homework design and so on. Their teaching level has been greatly improved, which provides support and guarantee for the healthy and sustainable development of our school.
Fourth, success depends on routines and details.
The teachers in this group do their daily work well, carefully study the teaching materials and outlines, and make teaching plans accordingly. The students carefully designed exercises, and the homework was graded. Individual students' homework has been changed beyond recognition. This paper analyzes the students' mistakes, finds out the causes of the mistakes, and adopts appropriate correction methods. Routine work has been put in place to ensure that chemistry always maintains a leading position in the whole region.
Five, more contact, improve the quality of students
In the teaching process, we should strengthen the connection with physics, geography and biology, pay attention to the consistency and scientificity of subject knowledge, and integrate knowledge on this basis, so that students can master scientific knowledge systematically. In the teaching process, students' reading ability, examination ability and analysis ability are cultivated through reading topics. Through exercise teaching, this paper introduces the application of mathematical thinking method in chemistry exercises, and improves students' comprehensive ability through lectures and exercises.
Summary of Chemistry Teaching in Grade Three
Time flies, the first semester of this school year is coming to an end. This half year is also a half year in which I have fulfilled my duties as a teacher, worked hard and made continuous progress in the teaching field. Review my teaching experience for half a year. This semester, according to the teaching plan, the teaching task was successfully completed. Now I summarize my work this semester as follows:
First, be a teacher, be tolerant of others, and treat every student with sincere care.
At work, I strive to be a teacher and tolerant of others. Strictly follow the requirements of enterprising, responsible, self-motivated, love school, love posts, love students, be willing to contribute, be brave in exploration and be proactive. Treat students equally, be tolerant, treat each student sincerely, care for each student, and teach patiently without losing strict requirements; To colleagues: unite and cooperate, respect each other and get along well; Be strict with yourself, set an example and be a teacher.
Two, strengthen the study of educational theory and business, pay attention to the effect of classroom teaching, and strive to improve the quality of teaching.
1. Prepare lessons carefully to lay a good foundation for completing teaching tasks with good quality and quantity.
(1) Earnestly implement the syllabus and study the teaching materials. Understand the basic ideas, basic concepts, structure, key points and difficulties of the textbook, and master the logic of knowledge.
(2) Master students' original cognitive structure, such as interests, needs, methods and habits, and what difficulties they may have in learning new knowledge, and take corresponding measures to help students master new knowledge comprehensively.
③ Innovative teaching methods. Seriously analyze the possible contradictions between teaching and learning, find out the existing problems and study the teaching methods. Pay attention to the effect of classroom interaction and improve students' learning enthusiasm.
2. Do a good job in classroom teaching and create a positive and strong learning atmosphere.
Organize classroom teaching, pay attention to all students, pay attention to information feedback, mobilize students' learning enthusiasm and attention, and maintain relative stability. Stimulate students' mood, make them have a happy mood, create a good classroom atmosphere, the classroom language is concise and clear, the classroom questions are for all students, pay attention to stimulate students' interest in learning, combine teaching with practice in class, arrange homework well and reduce students' burden.
3, do a good job in after-school counseling, increase training and make up the difference. At present, junior high school students are active and playful, lacking self-control ability, and some students can't finish their homework on time, so plagiarism happens from time to time. In view of this problem, we should do a good job in ideological education of students, implement this work in students' study guidance, and also do a good job in counseling and helping students in their study, especially in the transformation of underachievers. We should start with friendliness and praise, and pay equal attention to understanding and respecting every student.
4. Learn with an open mind and constantly improve your teaching level. Use the rest time to listen to other teachers with an open mind, learn from each other and discuss. Learn from others' good educational theories and methods to make up for their own shortcomings in the teaching process. In class, every class should be lively and efficient, easy to understand, easy to understand, and patiently answer every student's questions. Try to make every student like my chemistry class.
Third, attach importance to the senior high school entrance examination, basic teaching and ability training, and boldly try curriculum reform in teaching.
1. Attach importance to basic teaching and highlight ability training.
Attach importance to the teaching of basic knowledge, do a good job in the teaching of chemistry textbook knowledge, and strive to pass each chapter 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 according to their actual situation and try to reduce students with learning difficulties.
At the same time, we should master the basic skills, the skills of using chemical terms and the basic skills of experiments. 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 to effectively improve their experimental ability.
Attach importance to the process of acquiring knowledge and the cultivation of scientific inquiry ability. Strengthen the cultivation of students' scientific literacy, ability to find problems, analyze problems and solve problems in teaching. In the usual teaching and review, we should pay attention to prevent "emphasizing the conclusion, ignoring the process, emphasizing the simple application of mechanical exercises, and ignoring the analysis of problem scenarios and problem-solving ideas". We should attach importance to the process of acquiring knowledge and let students master the "basic subject thinking method" of learning chemistry. Let students personally experience and experience scientific inquiry activities, take the initiative to learn, and gradually form scientific inquiry ability.
2. 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. Fully prepared before class, the demonstration experiment has good effect. From the scientific attitude and standardized operation, students can be demonstrated and inspired 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.
This year's teaching has just ended. I will continue to explore and forge ahead in the future teaching and, as always, contribute to the education of the racecourse.
Summary of Chemistry Teaching in Grade Three 4
According to this semester's teaching plan and new syllabus, I finished my teaching task as scheduled. Do an organized, planned and step-by-step guided study and review, and do a good job of checking and filling gaps. In the past semester, I noticed the following problems in my teaching, which can be summarized as follows:
First, attach importance to the teaching of basic concepts of chemistry
The teaching of basic concepts 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, no.
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. 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.
Summary of Chemistry Teaching in Grade Three 5
In a blink of an eye, the short semester is over. Looking back on this semester, according to the teaching plan, I carefully prepared lessons, attended classes, corrected and commented homework in time, actively conducted after-school counseling, and guided students to review the senior high school entrance examination in an organized, planned and step-by-step manner to make up for the gap. Over the past semester, I have extensively absorbed all kinds of extracurricular knowledge, and constantly improved my education and teaching level. In teaching, I have been strict with students, respected students, carried forward teaching democracy, and let students learn and improve constantly. The students in our class successfully completed the learning task of chemistry class and took part in the senior high school entrance examination. The following is a summary of my teaching work this semester:
First, do a good job in preparing lessons, attending lectures, correcting homework and tutoring after class.
In order to prepare lessons, I carefully studied the textbook before class, grasped the depth and difficulties of the textbook, carefully designed teaching methods, arranged teaching links, set up consolidated exercises and homework, carefully organized classroom teaching, paid attention to all students, and paid attention to information feedback, so that each class not only grasped the key points of the textbook, but also broke through the difficulties, and students were relaxed and interested in learning. At the same time, stimulate students' emotions, make students feel happy and create a good classroom atmosphere; The classroom language is concise and clear, which overcomes the problem of repetition before; Ask questions in class for all students, and pay attention to stimulate students' interest in learning chemistry. In class, we should combine practice with teaching, arrange less but precise homework, and reduce the burden on students. To improve the quality of teaching, we should also do a good job of after-school counseling. Junior high school students are playful and lack self-control ability. They often fail to finish their homework on time, and some students copy their homework. To solve this problem, we should do a good job in students' ideological education, and make this work be implemented on the guidance of students' learning, and also do a good job in counseling and helping students' learning, especially the transformation of underachievers, and strive to start with friendliness and praise.
Second, change teaching methods to 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 deeply realize that students' greatest and most lasting interest in learning lies in whether the teacher's teaching methods are attractive. Only when teachers' teaching can attract students' attention, students can understand what they have learned and are interested in learning can classroom teaching be carried out smoothly, teachers' leading role be brought into play, students' initiative be mobilized and better practical results be achieved. Therefore, I attach great importance to the introduction of each lesson in teaching. According to the different teaching contents, I adopt different methods of introduction, such as introducing new lessons from reviewing old lessons, so that students can have a feeling of reviewing old ones and learning new ones, so that old and new knowledge can be well connected and new knowledge can naturally migrate, paving the way for students to accept new knowledge. At the same time, when giving lectures, try to use flexible and diverse methods to make students easy to understand and learn. The teaching method adopts the practice of "step by step, step by step", which makes students easy to accept and understand, and often pays attention to guiding students in learning methods, such as how to balance difficult chemical equations and how to answer inquiry questions. During the exam, I try to control the difficulty of the test questions, try to make students feel the taste of pears in one jump, and fully make students feel that learning chemistry well is not unattainable. As long as they are willing to work hard, they will certainly learn well.
Third, pay attention to the transformation of students with learning difficulties.
The training goal of the new chemistry curriculum is to make every student learn to live a healthy life, learn to have the necessary chemical science knowledge to adapt to modern life, and have certain scientific literacy, and at the same time, let students in different situations develop well and provide personalized guidance for each student's development. In chemistry teaching, in order to improve students' comprehensive quality and implement the new curriculum standards, we must attach importance to the transformation of students with learning difficulties. Comrade zankov once said: "One of the most important tasks of teachers is to make unremitting efforts in the development of all students, including poor students." Giving up a student with learning difficulties is nothing for a teacher, but for a parent, it means losing all hope. Due to the differences in innate conditions, growth environment and family education, it is normal for students to have differences in development. Therefore, in teaching, I pay special attention to the transformation of students with learning difficulties.
Loving students is the premise of transforming students with learning difficulties and the source of teachers' work motivation. Only when teachers respect, care, understand and tolerate them can they resolve the paranoia and inferiority of students with learning difficulties. Teachers' love is not only the condition for the healthy development of students' psychology, but also the condition for the healthy development of students' personality. Russell said: "Without the love of teachers, neither personality nor wisdom can be fully or freely developed." Yes, emotion needs emotional nurturing, and love needs love nurturing. Teachers' feelings for students affect their feelings and experiences of human feelings, and they will transfer this positive emotional experience to trust, respect and love others. Teachers should arouse students' love for knowledge and learning with their love for their own subjects and students.
High-intensity emotional experience, he can let a disappointed person see his potential energy again. Maslow said: "A positive experience can change a person's view of the world around him. It can liberate a person and make him more spontaneous and creative. " I have carried out some work from the following aspects:
1. Help students realize their potential, take positive self-suggestion and create a sense of success. Students with learning difficulties can't see their potential because of repeated failures, and blindly belittle themselves. Positive hints can be used to change students' misconceptions about themselves.
2. Take the relevant content of strengthening and improving students' advantage potential as a breakthrough. Everyone has his bright spots, some may not have ideal academic performance, but they work hard and have special skills in sports or other specialties. We should make full use of their potential or special skills, let them show their advantages, let them experience the joy of success, gain psychological balance and inspire their confidence and courage in learning.
3. Implement encouraging evaluation. Students with learning difficulties are not useless. What they lack is not criticism, but encouragement and affirmation. On the one hand, criticize them objectively and fairly without hurting their self-esteem and self-confidence, on the other hand, tap their bright spots and implement encouraging evaluation. Try to give them the opportunity to answer questions in class, always pay attention to their slight progress, and give encouragement in time to stimulate their self-motivation, establish and cultivate their self-confidence, gradually eliminate their inferiority complex and gradually improve their academic performance.
Fourth, pay attention to the process of acquiring knowledge and the cultivation of scientific inquiry ability.
To improve students' ability, it is necessary to strengthen the cultivation of students' scientific literacy, ability to find problems, analyze problems and solve problems in teaching. In the usual teaching and review, we can't "emphasize the conclusion, ignore the process, emphasize simple mechanical exercises, and ignore the analysis of problem scenarios and problem-solving ideas". Instead, we should attach importance to the process of acquiring knowledge and let students master the "basic subject thinking method" of learning chemistry.
In recent years, the content of scientific inquiry has been added to the chemistry test questions of Hainan senior high school entrance examination, which puts forward higher requirements for junior high school chemistry teaching. It is necessary to accurately grasp the direction of curriculum reform, take textbook knowledge as the basic inquiry content and the surrounding environment as the reference, so that students can experience and appreciate scientific inquiry activities, take the initiative to learn, and gradually form scientific inquiry ability.
Five, close contact with the reality of social life, master the application of knowledge.
In recent years, the senior high school entrance examination questions involve social hot topics such as life, production and environmental protection, and examine students' knowledge and ability from many angles. The examination of this kind of test questions has been gradually strengthened in recent years. This requires chemistry teaching to break through the limitation of simply instilling textbook knowledge, reduce the time and energy consumed by mechanical practice, and let students have time to read extracurricular knowledge such as science and technology. At the same time, according to the teaching content and the actual situation of students, I try to supplement some social hotspots such as life, production and environmental protection, so that students can contact and understand the society as much as possible, observe and analyze problems from the perspective of chemistry, and apply what they have learned.
