Thinking and reflection in the process of physics teaching included many aspects: 1. ** Experimental teaching **: Physics is based on experiments, but experimental teaching is often neglected. Many teachers were unwilling to carry out experiments because they found it troublesome. This was against the laws of physics teaching and the characteristics of the subject. In the process of teaching, students should be given more opportunities to carry out experiments to enhance their practical ability. 2. **" Taught " and " Church ": You can't simply assume that the knowledge points that students have learned in the textbooks don't need to be reviewed in class. You can't equate " taught " with " church ". Teachers usually tend to find new exercises for students to practice and comment on, hoping to improve their exam standards. However, when students still can't answer the basic test points and exercises that have been taught, they shouldn't simply blame the students. Different classes and learning situations would have weaknesses. Although it was difficult for teachers to fully grasp the situation of each student, they should usually be attentive and record the common problems of the students. During revision, they should focus on the key problems and repeatedly practice the frequently wrong problems to enhance the focus of the review and improve the effect. 3. ** Teaching philosophy and methods **: - ** Teaching philosophy **: The reflection of a teacher's teaching philosophy involves educational concepts, self-development awareness, sense of identity, professional development planning, educational system and reform, social environment, school atmosphere, etc. At present, some teachers focus on the reflection of teaching methods and ignore the reflection of teaching ideas. In fact, scientific and advanced teaching ideas play a leading role in the effective play of teaching methods. - ** Teaching Method **: Including classroom organization, classroom activities, teaching content, teaching objectives, teaching methods and media use, students 'learning behavior and attitude, learning methods, learning strategies, academic performance, teacher-student cooperation in the classroom, teacher-student conflict and handling, teacher-student relationship, etc. In the reflection of teaching methods, it was necessary to consider whether the teaching objectives were achieved, whether the students had gained anything, whether the teaching materials and methods could promote the development of teaching, and so on. At present, there were some teachers who had improper attitudes and made the reflection of teaching a mere formality. 4. ** Arousing students 'interest **: Junior high school students are in the transition stage from perceptual knowledge to rational knowledge. In teaching, pictures such as magical natural phenomena and beautiful landscapes can be used to give students a visual feast, causing students to marvel at physical phenomena, thus stimulating students' curiosity for physics. This way of introducing topics through perceptual knowledge conforms to the law of students 'cognitive development. 5. ** Respect for the student's main body status **: Teachers should guide students to understand physics knowledge, such as guiding students to raise the content of physics knowledge that they want to understand, such as the source of light, the way of transmission, and the speed of transmission. Then, they should guide students to guess these questions and let students become the main body of learning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Physics teaching should pay attention to experiments, understand that teaching is not equal to teaching, pay attention to the characteristics of students, arrange revision reasonably, and create new teaching methods to improve the effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a model essay on the reflection of the physics teaching process: ** I. Teaching objectives and results ** In physics teaching, the aim was to enable students to master physics concepts, formulas, and laws, and to be able to apply them to solve practical problems. At the same time, it was to cultivate students 'scientific thinking and inquiry ability. Judging from the results, some students could understand the basic knowledge better and performed better in class exercises and simple tests. For example, after the mechanics section, most students could use Newton's laws to solve basic force analysis problems. However, when it came to solving complex problems with comprehensive application of knowledge, there were still many students who showed difficulties, reflecting that their grasp of knowledge was not deep enough and flexible enough. ** 2. Use of teaching methods ** 1. ** Theory Teaching ** - When explaining physical concepts and laws, try many methods, such as introducing concepts through examples. For example, when he explained the concept of pressure, he introduced the relationship between pressure and the area of force by using the different effects of the nail tip and nail cap. However, during the teaching process, some students found it difficult to understand some abstract concepts, such as electric field and magnetic field, only by examples and explanations. - In terms of formula derivation, it focused on the logical derivation process and cultivated the students 'logical thinking ability. However, during the derivation process, sometimes the rhythm was not grasped well, causing some students to be unable to keep up. For example, when deducing the kinetic energy theorem, it was difficult for students with weak mathematical foundations to understand. 2. ** Experimental Teaching ** - Experimental teaching could stimulate students 'interest in learning and desire to explore. When conducting electrical experiments, students could connect the circuit themselves and observe the physical phenomena in the circuit. For example, in the experiment to explore Ohm's Law, students could change the resistance and voltage to observe the changes in the current and have a more intuitive understanding of Ohm's Law. - However, there were also some problems in experimental teaching. First, the experimental equipment would sometimes malfunction, affecting the progress of the experiment, such as the inaccurate reading of the ammeter. Secondly, in the experimental group cooperation, some students 'participation was not high, and there was a phenomenon of "free rider", so they did not really invest in the experimental exploration. ** 3. Analysis of Students 'Learning Status ** 1. ** Learning attitude ** - Some students had a strong interest in physics. They actively participated in class discussions, completed homework, and actively explored some physics extra-cursory knowledge. However, there were also some students who did not have a good learning attitude. They thought that physics was difficult to learn and developed fear of difficulty. They were not focused in class and plagiarized homework from time to time. 2. ** Learning ability difference ** - There was a huge difference in learning ability between students. Outstanding students were able to quickly understand new knowledge and draw inferences from one example. They were able to flexibly use a variety of methods to solve physics problems. Students with weaker learning abilities would have more difficulty understanding basic concepts and rules. They would need more time and guidance. For example, when studying electromagnetic induction, excellent students could understand Lenz's law through their own analysis, while some students needed to practice and explain in detail to master it. ** IV. Teaching improvement measures ** 1. ** Teaching method adjustment ** - For the teaching of abstract concepts, more multi-media resources could be used, such as animations to demonstrate the distribution of electric field lines and magnetic induction lines, to help students build an intuitive impression. - In the process of formula derivation, the pace should be adjusted according to the feedback of the students. For the steps that were more difficult to understand, some auxiliary examples could be added or explained step by step. 2. ** Experimental teaching improvement ** - The inspection and maintenance of the experimental equipment should be strengthened before the experiment to ensure that the experimental equipment was running normally. - When the experimental group was divided into groups, it was necessary to reasonably match the students, clarify the tasks of each student, and increase the participation of the students. 3. ** Student Counseling ** - For students with bad learning attitudes, they should strengthen their education and stimulate their interest in learning by telling the importance of physics and the stories of some physicists. - For students with weak learning ability, more extra-cursory tutoring should be provided, such as organizing study groups to conduct targeted tutoring and answering questions. Through thinking and reflecting on the physics teaching process, the advantages and disadvantages of the teaching were clarified, and the corresponding improvement measures were put forward. It was hoped that the teaching quality could be continuously improved in the future, and the students 'learning level of physics could be improved. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an example of a physics inquiry experiment teaching design and reflection: ** I. Teaching Design ** 1. ** Experiment topic selection ** - For example,"Exploring the factors that affect the magnitude of sliding friction". This topic was closely related to daily life, such as the anti-slip design of soles and the brake system of cars. It also covered important knowledge points of mechanics in physics. 2. ** Teaching goal ** - ** Knowledge and Skill Target ** - Students can understand the concept of sliding friction and know which factors are related to the magnitude of sliding friction. - Students learn how to use a spring tester to measure sliding friction. - ** Course, Method, and Target ** - Through designing experimental plans, carrying out experimental operations, and analyzing experimental data, students 'scientific inquiry ability was cultivated, including the use of the control variable method. - To improve the students 'ability to observe, analyze, and summarize. - ** Emotions, attitudes, values, goals ** - To stimulate students 'interest in physics experiments and cultivate students' rigorous scientific attitude and teamwork spirit. 3. ** Prepare the experimental equipment ** - Spring force meters, flat surfaces of different coarseness (such as glass, wood, sandpaper), wood blocks of different quality, thin threads, etc. 4. ** Experimental teaching process ** - ** Introduction Stage ** - By showing pictures or videos of some phenomena related to friction in life, such as people slipping easily when walking on ice but walking steadily on ordinary roads, he asked,"What factors affect the stability of our walking? What does this have to do with the friction we're going to explore today?" - ** Hypothesis-Raising Stage ** - Guide the students to propose that the factors that affect the sliding friction force may be the thickness of the contact surface and the weight of the object. - ** Design experiment segment ** - Regarding the factor of the rough contact surface: - The experiment was designed with the control variable method. The quality of the wood block was kept constant. The wood block was pulled horizontally and uniformly on the glass, wood, and sandpaper with a spring tester. The indication of the spring tester was measured and recorded. This indication was the sliding friction force. - Considering the weight of the object: - Choose a flat surface (such as a wooden board) with the same degree of coarseness, change the quality of the wooden block, and use the spring ergometer to pull the wooden block of different quality horizontally at a uniform speed. Then measure and record the number of the spring ergometer. - ** Experiment segment ** - The students were divided into groups to conduct the experiment. Each group was responsible for exploring a factor. During the experiment, the teacher inspected each group and corrected the students 'mistakes in time, such as whether the use of the spring ergometer was standard (to be horizontal and pull at a uniform speed). - ** Analysis of data and conclusion ** - Each group organized the experimental data into a table, analyzed the data, and came to a conclusion. For example, from the experimental data of the contact surface's rough degree, it could be found that the rougher the contact surface, the greater the sliding friction force. From the experimental data of the object's weight, it could be seen that the heavier the object, the greater the sliding friction force. - ** Summing Up and Extending Stage ** - The teacher guided the students to review the entire process of the inquiry, emphasizing the importance of controlling variables in the experiment. Then he asked an expansive question, such as,"How do I increase or decrease the friction in my life?" Let the students use the knowledge they have learned to think and discuss. ** 2. Reflection on Teaching ** 1. ** Strengths ** - ** In terms of achieving goals ** - Through the experimental exploration, the students had a deeper understanding of the concept and influencing factors of sliding friction, and were able to skillfully use the spring tester to measure sliding friction, achieving the knowledge and skill goals. - During the experiment, the students actively participated in the design of the experiment, the operation and the analysis of the data, effectively cultivating the ability of scientific inquiry, and the process and method goals were achieved. - ** Student interest and participation ** - The introduction of the experimental topic with the phenomenon of life stimulated the students 'curiosity and interest. In the group experiment, the students cooperated actively and participated more, which was conducive to cultivating the spirit of teamwork. 2. ** Not enough ** - ** Experiment Operation ** - Some students were using springs to measure the time. Although they had been corrected by the teacher, they were still not familiar with the operation, which might affect the accuracy of the experimental data. In the future teaching, special training on the use of experimental instruments needed to be strengthened. - ** Exploring the depth ** - When analyzing the experimental data and drawing conclusions, some students simply drew conclusions based on the surface phenomena of the data, lacking in-depth thinking about the physical principles behind the data. For example, there was no in-depth discussion on the microscopic explanation of friction. In the follow-up teaching, guidance in this area could be added. - ** Time management ** - In the student grouping experiment segment, due to the different experimental speeds of each group, the overall time control was not accurate enough, and the final expansion segment was a little rushed. In the future teaching design, it was necessary to arrange the time of each teaching segment more reasonably. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a model essay for a physics teaching reflection journal: ##Physics Teaching Reflection Research Diary In the process of participating in physics teaching, research activities have become an important way to continuously improve my teaching ability. Through in-depth reflection on teaching practice, I have gained a lot. ** I. Reflection on teaching philosophy ** Traditional physics teaching often focused on imparting knowledge, which emphasized the students 'memory of basic knowledge such as physics concepts and formulas, while ignoring the main role of students in the learning process. During my research and study, I deeply realized the importance of the three-dimensional teaching objectives of the new curriculum concept, which emphasized "knowledge and skills","process and method", and "emotional attitude and values". This made me realize that teaching design should be based on the analysis of students 'learning conditions and learning situations. For example, when teaching physics, one had to consider the influence of the students 'existing knowledge and previous concepts on their learning of new knowledge. At the same time, I also began to focus on guiding students to explore independently in teaching, connecting the learning content with the actual life of the students to stimulate their interest in learning and cultivate their scientific thinking ability. ** 2. Reflection on teaching methods ** In my previous teaching, I used the lecture method more often. Although this method has a certain efficiency in transmitting knowledge, it is insufficient for the students to develop their independent inquiry ability and scientific thinking. In the course of my research, I saw many excellent teaching cases, such as the elicitation method, which allows students to bring questions to the teacher and students to study, discuss, and solve problems together. I tried to use this method in my own class and found that the students 'participation increased significantly and the classroom atmosphere became more lively. In addition, according to the teaching content, I also tried to design some traditional lectures into inquiry classes, so that students can grasp knowledge in the process of inquiry and cultivate their hands-on ability and innovative thinking. For example, when explaining physics experiments, it was no longer just a simple demonstration. Instead, students were divided into groups to carry out experimental exploration. From proposing assumptions, designing experimental plans, to reaching conclusions, students were allowed to participate in the entire process. This not only increased the students 'interest in physics, but also deepened their understanding of knowledge. ** 3. Reflection on teaching methods ** With the development of modern educational technology, the application of multi-media in teaching has become increasingly widespread. The research made me realize my shortcomings in teaching methods. Previously, although I used to play pictures, lessons, and videos on the internet, I didn't use them often. I didn't integrate the teaching content and the media resources carefully enough. After I learned that many teachers made use of multi-media resources, such as self-made teaching aids and multi-media digital laboratories, to make the content that was originally difficult to teach and learn easier, I began to try to make full use of multi-media resources in teaching. For example, when explaining abstract physical concepts, animation was used to let students understand the meaning of the concept more intuitively; when explaining physical phenomena, relevant video materials were played to let students have a deeper feeling. ** IV. Reflection on the students 'learning situation ** Students have different attitudes and learning abilities towards physics. Some students were passionate about physics and could actively participate in classroom interactions and after-class explorations, while some students were afraid of physics and were not enthusiastic about learning. Through research, I realized that this might be related to the fact that I did not pay enough attention to the individual differences of students in the teaching process. In the future, I plan to design different teaching tasks and questions for students of different levels. I will use a layered teaching method to meet the learning needs of different students. At the same time, it was important to cultivate the students 'emotions in learning physics, so that they could realize the importance and interest of physics, thus stimulating their interest in learning. ** 5. Reflection on my own professional growth ** The research activities allowed me to get to know many excellent teachers and I learned a lot of valuable experience from them. In the process of teaching, I also found that my physics knowledge still needs to be further improved, especially in some cutting-edge physics knowledge and cross-disciplinary knowledge. In order to better guide the students, I decided to strengthen my own studies. I would read physics books and journals regularly, participate in physics academic exchange activities, and constantly broaden my knowledge and improve my professionalism. In short, this research activity made me have a deep reflection on physics teaching philosophy, teaching methods, teaching methods, students 'learning situation, and my own professional growth. In the future teaching work, I will turn these reflections into practical actions, constantly improve my teaching process, improve the quality of teaching, and provide better guidance for students 'physics learning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflection on the teaching of physics in life: In the teaching of physics in life, there are some places that are done well, but there are also many problems. In terms of teaching content, although it was combined with life examples, some examples were not novel enough to fully stimulate the students 'interest. In terms of teaching methods, explanations were sometimes too traditional and lacked interaction, resulting in low student participation. In terms of the use of teaching resources, the integration of some modern scientific and technological resources was not sufficient. " Modification measures: update the teaching content and find more novel and interesting physics examples that are close to life. The innovative teaching methods were mostly group discussions, experimental inquiry, and other highly interacting methods. Make full use of modern scientific and technological resources, such as the use of animation to demonstrate physical phenomena, etc., to improve the teaching effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

To write a good reflection on the physics teaching process, one could start from these aspects. In terms of teaching content, he wanted to see if he had explained the concepts and principles of physics clearly. For example, when talking about Newton's laws, did the examples be clear enough for the students to understand? If it was about electromagnetic induction, was the formula derivation clear? In terms of teaching methods, should they use lecture method, experiment method, or group discussion method? If he used the lecture method, wouldn't it be too boring? Would all the students be listening? If it was an experimental method, would the experimental equipment be fine? How was the student participation rate? Student feedback was also important. Looking at the students 'homework completion, he could see if there were many mistakes caused by not understanding the teaching content. The students 'expressions and questions in class could also reflect their acceptance of the teaching. And whether or not he had achieved his teaching goals. The original plan was to let the students master a certain physics knowledge point. Through tests or classroom questions, they would find out whether most students had really mastered it. In short, if he reflected on the physics teaching process from these perspectives, the content he wrote would be better. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a brief reflection on the teaching of physics and life (middle school students): ** I. Strengths in Teaching ** 1. ** Contact a life example ** - In the teaching process, it was important to link physics knowledge with daily life phenomena. For example, when explaining the reflection of light, common phenomena such as mirror reflection and water reflection were mentioned. This would help students understand abstract physics concepts, increase their interest in physics, and let students realize that physics was right beside them. 2. ** Experimental Teaching Support ** - He arranged some simple experiments, such as exploring the law of light reflection. Through the experiment, the students could see the physical phenomenon intuitively, which enhanced their perceptual knowledge and also cultivated the students 'observation ability and hands-on ability. ** II. Problems in teaching and improvement measures ** 1. ** Question * - Some students had difficulty understanding the connection between physics knowledge and reality. Although there were many life examples, some students still couldn't relate it to the physics knowledge they learned. It might be because the students weren't sufficiently guided to think deeply during the explanation. - In experimental teaching, due to the individual differences of students, some students could not keep up with the rhythm of the experimental operation, resulting in poor experimental results. 2. ** Modification measures ** - When explaining the connection between physics knowledge and life, more interaction teaching methods were used, such as questions, group discussions, etc., to guide students to actively think about the physics principles behind life phenomena, rather than simply imparting knowledge. - In terms of experimental teaching, they had to understand the students 'experimental foundation in advance and divide them into reasonable groups so that the students with strong operational abilities could drive the weaker students. He also explained the experimental steps and precautions in more detail before the experiment to ensure that every student could participate in the experiment and truly understand the physics knowledge contained in the experiment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a lesson plan and reflection example about the confusion and thinking introduced in junior high school physics teaching: ** 1. Teaching plan ** #"Design for the Introduction of Junior High School Physics Teaching" ##(1) Teaching objectives 1. ** Knowledge and Skill Target ** - To let students understand the importance of the introduction process in physics teaching, and to be able to identify different types of effective introduction methods. - Through the analysis of specific cases, students could grasp the ability to design suitable introductions for different physics knowledge points. 2. ** Course, Method, and Target ** - Through group discussions and case studies, the students 'cooperative learning ability and critical thinking ability were cultivated. - To guide students to constantly sum up experience in the learning process and improve their ability to design teaching strategies. 3. ** Emotions, attitudes, values, goals ** - To stimulate students 'interest in junior high school physics teaching and enhance their enthusiasm for physics education. - Cultivate students 'serious and responsible attitude towards teaching and actively explore. ##(2) Difficulties in Teaching 1. ** Teaching Focus ** - Master the various ways of introducing physics teaching and their applicable scenarios. - Understand how to design a fascinating teaching introduction based on the content and student characteristics. 2. ** Teaching Difficulties ** - How to ensure that the introduction of teaching could attract students 'attention and closely follow the teaching objectives, avoiding excessive entertainment or deviation from the theme. ##(3) Teaching Method 1. Teaching Method: Explain the basic concepts, importance, and common types of teaching. 2. Case analysis method: Through actual junior high school physics teaching cases, analyze the advantages and disadvantages of different introduction methods. 3. Group discussion method: organize students to discuss the best way to introduce specific teaching content and promote the exchange of ideas between students. ##(4) Teaching process ### 1. Course Introduction (5 minutes) - Through an interesting physics experiment (such as static electricity absorption of small paper scraps), the students were asked why this phenomenon occurred, which led to the topic of physics teaching in this lesson. ### 2. New lecture (25 minutes) - The concept of introductory teaching: In physics teaching, introductory teaching was the beginning of the teaching process. It was designed to attract students 'attention, stimulate students' interest in learning, and pave the way for the learning of new knowledge. - Introduction of common teaching methods - Experiment Introduction: Take "Exploring the factors that affect the magnitude of buoyancy" as an example. The teacher can first demonstrate the floating and sinking of different objects in the water to arouse the students 'curiosity and then guide the students to think about the factors that affect buoyancy. - Question introduction: When explaining the concept of "pressure", ask the question,"Why is it that people wearing skis don't sink easily in the snow, but people wearing ordinary shoes sink easily?" Stimulate the students 'thinking and draw out the knowledge points related to pressure and force bearing area. - [Story Introduction: Tell the story of how Archmedes discovered the law of buoyancy, and then lead to the study of buoyancy related knowledge.] - Introduction of life examples: For the phenomenon of "light refraction", you can introduce it from the phenomenon of chopsticks that look "bent" when inserted into the water in daily life. This will make the students feel that physics is right beside them. - The students were organized into groups to discuss the characteristics and application scenarios of different introduction methods. Each group chose a physics knowledge point (such as Ohm's law in electricity, heat transfer in thermotics, etc.), designed a teaching introduction method, and explained the reasons. ### 3. Class summary (10 minutes) - Representatives of each group were invited to share the results of the discussion. Teachers were invited to comment and summarize, emphasizing that teaching objectives, students 'age, knowledge level, and the characteristics of the teaching content should be fully considered when designing the teaching introduction. ### 4. Class assignment (5 minutes) - Arrange homework: Ask the students to design a teaching introduction plan based on the knowledge point of "friction" and briefly explain the design ideas in writing. ** 2. Reflection on Teaching ** ##(I) Success 1. ** Diverse teaching methods ** - Through the lecture method, students had a clear understanding of the basic concepts and common types of teaching introduction. The case analysis method made students more intuitively feel the application of different introduction methods in actual teaching. The group discussion method stimulated the enthusiasm and initiative of the students, and cultivated the students 'cooperative learning ability and innovative thinking. 2. ** Student participation ** - During the group discussion, most of the students were able to actively participate in the discussion and put forward some creative teaching introduction plans. This showed that the students had a strong interest in the topic of physics teaching introduction, and to a certain extent, they had mastered the relevant design methods. ##(2) Deficiency 1. ** Time Control ** - During the group discussion session, due to the students 'heated discussion, the time was slightly exceeded, making the class summary part a little rushed. There was not enough time to comment on all the students' creativity in depth. 2. ** The depth of understanding of some students ** - Although most students could understand and design the teaching introduction plan, there were still a few students who had difficulties in understanding how to integrate it with the teaching objectives, reflecting that these students did not have an accurate grasp of the teaching objectives. ##(3) Modification 1. ** Time management optimization ** - In the future, the time of each teaching session should be more strictly controlled. The time limit for the discussion should be clearly informed to the students before the group discussion, and timely reminders should be made during the discussion process to ensure that each session could be completed smoothly. 2. ** Tailored Counseling ** - For students who had difficulties in understanding, they would be given individual tutoring after class to help them understand the relationship between teaching objectives and teaching introduction through more case studies, so as to improve their teaching design ability. The introduction of physics in junior high school required the teacher to carefully design and take into account various factors to improve the teaching effect and stimulate the students 'love for physics. Through continuous practice, reflection, and improvement, teachers could constantly improve their teaching standards. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many situations in the buoyancy review class. In terms of teaching objectives, students should be taught to master the calculation method of buoyancy, the principle of Archmedes, the conditions for objects to float and float, and the application of buoyancy. However, there were some problems with the teaching process: 1. ** Teaching content ** - [Target direction and difficulty grasp: Although the revision content is clear, there is still room for improvement in the direction of the target and the grasp of the depth of the difficulty.] For example, some revision lessons had some shortcomings even though they had completed the content. The revision content did not completely point to the goal, and the depth of knowledge needed to be improved. - ** Problem Setting and Connection **: The problem setting should be able to review the knowledge points and compare the questions to reflect the differences, guide the solution method, and realize the knowledge transfer. However, in actual teaching, sometimes there would be a lack of connection between the questions, so that the value of the questions could not be fully displayed, and the opportunity to guide the students to solve the questions was missed. 2. ** Teaching Difficulties ** - ** Outstanding points **: Some of the revision lessons were not very difficult. For example, the concept of buoyancy and the principle of Archmedes were both important and difficult points. However, they were not outstanding enough in the teaching, and the process of obtaining the principle was difficult. - ** Difficulty of exercises and students 'situation **: Buoyancy knowledge is comprehensive, and the difficulty of exercises is high. Students are easily confused, resulting in more classes for new lessons and exercises. Teachers are also confused about whether they need so many classes. 3. ** Teaching methods ** - ** Students 'subjective initiative **: The teacher's teaching method sometimes restrains the students too much, limits the students' thoughts, and does not give full play to the students 'subjective initiative. It is not prepared enough to deal with the "unexpected" situations that the students guess. For example, the students' guesses about the factors related to buoyancy may have limitations. The teacher should guide them. - ** Student participation and practice questions **: In the teaching process, there are not enough displays, and the participation of all the students is not enough. The practice questions are not selected properly, and there is no gradual progression. In addition, when there was more teaching content, students would have less time to practice, so they should choose exercises with a low starting point, low difficulty, and one-step calculation to consolidate their knowledge. 4. ** Teaching Success ** - "** Teaching method innovation **: We can stimulate students 'interest through innovative teaching methods. For example, we can perform magic in the introductory segment (such as" Obedient Little Fish "), and then explain the principles with physics knowledge. This can stimulate students' interest and meet the teaching goal of applying what they have learned. - ** Understand the students 'knowledge mastery **: Arrange activities such as "Buoyancy in Life" and let the students explain the application of buoyancy and think about the principle. This can not only motivate the students to answer questions, but also understand the students' mastery of buoyancy. - ** Temporary change **: In the classroom teaching, according to the students 'deep understanding of buoyancy knowledge, make temporary adjustments to the teaching content, such as the teaching process of the weighing method. Put the time on the principle explanation, which can achieve better teaching results. - ** After-class summary **: Set aside enough time (such as 12 minutes) for the after-class summary segment. By typing questions on the projection, such as "What knowledge have you learned (both in and out of class)","What is the use of this knowledge", etc., students can summarize and consolidate their knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
