An Analysis of the Teaching Materials of Biology (1)
The following is an analysis of some of the contents of the biology elective compulsory textbook: ** 1. The environment in which cells live ** 1. ** Internal environment composition ** - The internal environment was mainly composed of blood plasma, tissue fluid, and mucus. Blood plasma was the environment in which blood cells lived, tissue fluid was the environment in which most tissues and cells lived, and mucus was the environment in which spleen cells lived. - The human respiratory tract, respiratory cavity, digestive tract, lacrimal glands, urethra, and so on were connected to the external environment. The fluids in them, such as digestive juice, tears, urine, sweat, and saliva, did not belong to the extra-cellular fluid. 2. ** Relationship between the concentration of substances in the internal environment ** - The concentration of oxygen was in the order of blood plasma, tissue fluid, and cellular fluid. The concentration of carbon dioxide was in the order of cellular fluid, tissue fluid, and blood plasma. 3. ** The role and stability of the internal environment ** - The internal environment was the external environment in which cells lived. Not only did cells rely on the internal environment, but they also participated in the formation and maintenance of the internal environment. The steady-state of the internal environment included the relative stability of the osmic pressure and the ph value. After excessive sweating or severe diarrhea, if you only drink water and do not supplement salt, the osmolarity of the internal environment will decrease, which may cause the cells to absorb water and swell. Embosom patients will affect the pH in the internal environment due to poor breathing. If the human body's capillaries were more penetrative, it would lead to tissue edema. ** 2. Cell structure and function ** 1. ** Cell membrane ** - It had many functions, such as selective penetrability, which could control the entry and exit of substances into cells, allowing only certain substances to pass through and preventing others from passing through; it had the function of substance transport, such as the trans-membrane transport of some ions and small molecules; and it also had the function of signal transmission, which could receive external signals and transmit information into cells. 2. ** Nucleus ** - It was composed of nuclear membrane, Chromatin, and so on. It was a genetic information bank that stored the genetic information of cells. It played a central role in the storage of genetic information and the regulation of gene expression. It was the control center of cell metabolism and inheritance. 3. ** Cell organ ** - The mitochondria was the main place for cells to carry out oxygen breathing and provide energy for cell life activities. The ER was involved in the synthesis and processing of protein and other substances, as well as the synthesis of fats. The Golgi apparatus mainly processes, sorts, and packages the protein from the ER. Different organelle cooperated with each other and played irreplaceable roles in the cell metabolism process. There was also a relationship between the organelle. For example, the protein processed by the ER was transported to the Golgi apparatus for further processing. 4. ** Cell metabolism ** - Cell metabolism included processes such as glycolsis and the tricarbadic acid cycle. Glycolysis is the first stage of cell breathing, breaking down glucose into methyruvate and producing a small amount of energy. The tricacid cycle was carried out in the mitochondria, which further broke down the Pyruvate and released a large amount of energy. Cell metabolism provides energy for cell life activities and is the basis for maintaining cell survival and function. Read more exciting novels for free
Analysis and Reflection on the Teaching Materials of Biology in Senior High School
The following is the analysis and reflection of the high school biology textbook: ** 1. Teaching material content arrangement system ** 1. ** Reasonability of the architecture ** - The new textbook arrangement system paid more attention to the logical continuity of knowledge and the cognitive laws of students. For example, the 2019 edition of high school biology textbooks had made adjustments to the arrangement of compulsory and elective compulsory content. From the first compulsory course, Molecules and Cell, to the second compulsory course, Heredity and Evolution, to the second compulsory course, the second compulsory course. The arrangement was gradual and in line with the development of students 'cognitive abilities at different stages of learning. Compared to the old version of the textbook, the arrangement of the new textbook made the progression of knowledge clearer, helping students gradually build a complete biological knowledge system. - This was also reflected in the internal content adjustment of the compulsory one, Molecules and Cell. For example," The process of establishing cell theory " was moved to the first section so that students could first establish the development of cell research when they began to learn about cell-related knowledge. This would lay the foundation for the subsequent in-depth study of the various structures and functions of cells. 2. ** Impact on Teaching ** - This change in the arrangement system put forward new requirements for teachers 'teaching. Teachers needed to readjust their teaching plans and teaching ideas to adapt to the logic of the new teaching materials. For example, in the teaching process, they had to pay more attention to the transition and connection between knowledge points. They could no longer follow the order of teaching in the old version of the textbook. At the same time, teachers need to guide students to understand the purpose of the textbook arrangement and help students learn how to effectively prepare and review according to the textbook structure. ** 2. Changes in the teaching materials ** 1. ** Increase, decrease and adjustment of content ** - ** Added content ** - A lot of content was added to the compulsory one," Molecules and Cell." For example, Chapter 2 added content such as " The reason why water is a good solute in cells " and " The reason why water has a high specific heat capacity ". These contents helped students to understand the characteristics and functions of the substances in cells more deeply. Adding the content of " chitins " and adding the types of " glycan " had enriched the students 'understanding of the biological molecules in cells. - In Chapter 3, contents such as " rough surfaced ER " and " smooth surfaced ER " were added. This allowed the students to have a more detailed understanding of the submicroscopic structure and function of cells. These new contents reflected the new progress in biology research, which helped to broaden the students 'knowledge and cultivate the students' spirit of scientific inquiry. - ** Removal of content ** - For example, in chapter 1, the content of " Life activities cannot be separated from cells " was deleted. This might be because under the new teaching material arrangement system, relevant knowledge could be infiltrated or integrated through other means. However, teachers might need to think about how to make students deeply understand the close relationship between cells and life activities in the absence of this clear statement. - ** Modifications to the content ** - For example, in Chapter 2," the water content in cells is 85% - 90%" was changed to " the water content in cells is 70% - 90%". This adjustment was more in line with the accuracy of scientific research. Teachers should pay attention to updating their knowledge in time and guide students to pay attention to the accuracy of scientific data. 2. ** Impact on teaching and student learning ** - For teachers, the increase or decrease of content meant that the focus and difficulty of the teaching content had also changed. Teachers needed to re-determine the focus of teaching and carefully design teaching methods for the new content to ensure that students could understand and master it. As for the deleted content, they should avoid over-explaining it in the teaching. - For students, the new content increased the breadth and depth of learning, requiring students to have stronger learning ability and scientific thinking ability. Students needed to learn to explore new knowledge under the guidance of new teaching materials and be able to integrate new and old knowledge. ** 3. Teaching materials and subject accomplishment cultivation ** 1. ** The embodiment of core discipline accomplishment ** - The new teaching materials could cultivate and develop students 'core academic accomplishments by creating real situations, focusing on big concepts, and infiltrating subject ideas. For example, in the compulsory one, Molecules and Cell, by adding scientific history content related to cell breathing and photosynthesis, such as Hill reaction and Arnon experiment, students could understand the process and methods of scientific inquiry while learning scientific knowledge, and cultivate their scientific thinking ability. - When introducing the structure and function of cells, by emphasizing the relationship between the various parts of the cell and the relationship between the cell and the environment, the structure and function of the concept of life, as well as the concept of matter and energy, were infiltrated, which helped students build a complete concept of life. 2. ** Enlightenment for Teaching Practice ** - In the teaching process, teachers should pay attention to excavating the core elements of the subject in the teaching materials, not just limited to the imparting of knowledge. For example, when explaining the material transport of cells, students could be guided to analyze the differences and connections between active and passive transport from the perspective of material and energy. At the same time, through the creation of real teaching situations, such as the use of examples in life or actual cases of biological science research, to stimulate students 'interest in learning and cultivate students' ability to use what they have learned to solve practical problems. ** 4. Regional differences in the use of teaching materials and prospects ** 1. ** Regional differences ** - Taking Sichuan Province as an example, when using the old version of the teaching materials, due to the tight schedule, the high schools had adjusted the teaching progress of the teaching materials, and would continue to teach elective content in the last year of high school. As for the use of the 2019 edition of the teaching materials, it was still uncertain. The differences in the use of teaching materials in different regions reflected the differences in educational resources, teaching schedules, and college entrance examination policies in different regions. 2. ** Future prospects for the use of teaching materials ** - With the continuous advancement of the curriculum reform, it was hoped that the use of teaching materials in the future would be more suitable for local conditions. At the same time, it was also necessary to pay attention to the fairness of education nationwide. The compilation of teaching materials could further consider the educational needs of different regions and write some flexible teaching materials or teaching auxiliary materials so that each region could better arrange teaching according to their own situation. Moreover, with the continuous development of biology research, the teaching materials needed to be updated to maintain their scientific nature. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis Report on the Teaching Materials of Medicine and First Aid in Junior High School Biology
The following is the summary of the analysis report of the junior high school biology textbook "Medicine and First Aid": ** 1. Teaching Materials ** 1. ** Safe Medication ** - Basic concept: Choose the appropriate type of medicine according to the patient's condition, physique, and the effect of the medicine. Use the appropriate method, dosage, and time to accurately administer the medicine to maximize the effect of the medicine and reduce adverse effects. - Drug classification: Including prescription drugs (purchased with a prescription and taken according to the doctor's advice) and over-the-counter drugs (purchased without a prescription and taken according to the instructions, referred to as over-the-counter). - Medication requirements: Before use, read the drug instructions carefully, covering the name of the drug, main ingredients, effects and uses, adverse reactions, precautions, usage and dosage, preparation and specifications, production date, and expiration date. 2. ** First aid ** - Emergency call: When dialing "120", you must accurately describe the address and dangerous situation. - CPR: It includes external cardiac compression and artificial resuscitation (mouth-to-mouth blowing). The sequence is external cardiac compression → opening the air passage → artificial resuscitation. - Bleeding and bleeding control: For venous bleeding, press the far end of the heart to stop bleeding; for artery bleeding, press the near end of the heart to stop bleeding. ** 2. Teaching Points and Difficulties ** 1. ** Teaching Focus ** - Basic knowledge of safe medication, such as drug classification, medication requirements, etc. 2. ** Teaching Difficulties ** - He distinguished between prescription and over-the-counter drugs, designed the travel kit, and the operating sequence and steps of CPR. ** 3. Teaching objectives (from the three dimensions of knowledge and skills, process and methods, emotional attitudes and values)** 1. ** Knowledge and Skills ** - It could distinguish between common prescription drugs and over-the-counter drugs. - Understand the basic knowledge of safe medication, including the names, effects, and usage of some commonly used drugs. 2. ** Method and process ** - To train the students to understand all aspects of medicine knowledge and practical application ability by reading the drug instructions. 3. ** Emotions, attitudes and values ** - Cultivate the students to use the right medicine according to the condition, and to be serious and responsible for their own and others 'health. ** 4. Teaching preparation and teaching process ** 1. ** Teaching preparation ** - Before class, the students collected the instructions for use of some drugs, commonly used emergency telephone numbers, and went to the school infirmary to understand the key points of first aid. 2. ** Teaching process ** - Through the experience of using drugs in their lives, they could be introduced into the teaching to guide students to analyze the problems related to safe use of drugs. For example, by analyzing the drug instructions in the teaching materials, they could practice understanding the instructions. The students were organized into small groups to design travel medicine boxes. First aid teaching content was introduced through examples, including the correct dialing of "120" emergency number, artificial resuscitation, extra-chest cardiac compression, bleeding types and bleeding control methods, etc., and various methods such as simulation practice and role-playing could be used to let students experience and master relevant knowledge and skills. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis of Table Tennis Teaching Materials
The table tennis teaching materials were analyzed as follows: 1. Techniques and Tactics 1. The importance and continuity of basic techniques - In the teaching of different grades, the teaching of table tennis skills had a certain degree of continuity. For example, in the seventh grade, students were required to master the basic skills of hitting the ball flat, using the technique of pushing and blocking to hit the ball back, and being able to play a certain number of rounds. On the basis of improving the quality of the return ball, the eighth grade students would further learn how to send out the backspin ball and rub the ball, and learn more about the spinning ball technique. Forehand attack was also an important basic technique. It was the technique of hitting the ball from the forehand position and an important scoring method in table tennis. Combining it with the backhand push and the flat shot technique could improve the overall level of individual techniques and tactics. 2. The Teaching Meaning of Spinning Ball - Understanding the rotation of the ball was the prerequisite for playing table tennis well. In a match, creating a spinning ball could confuse the opponent, and returning the spinning ball could seize the opportunity, which was a magic weapon to win the match. By letting the students understand the rotation of the ball, they could increase their interest in table tennis and experience its charm. Second, the value of the teaching content 1. The comprehensive cultivation of students 'abilities - The content of the teaching materials could help improve the students 'technical and tactical level. At the same time, by organizing group competitions, it could check the effect of the students' learning and application of techniques, cultivate the students 'ability to cooperate and help each other, and adapt to the changes in the competition. This would develop the students' physical and mental health in an all-round way and improve their physical fitness. 2. A design for students of different grades - The technical difficulty of the teaching materials for different grades gradually increased. For example, in the third and fourth grade of primary school, they began to raise the requirements for the basic movement techniques, collective cooperation, and application rules of small balls. They began to introduce the concept of tactics. By the sixth grade, most students were familiar with the basic play of table tennis, but there were still shortcomings in the application of tactics. Third, the guidance of teaching materials on teaching methods 1. Teaching sequence from basic to advanced - In terms of teaching suggestions, it emphasized the teaching order from basic to improvement, from simple to difficult. For example, the basic skills such as the backhand attack were taught first, and then the spinning ball technique was taught. This would help students gradually establish a mastery system of table tennis techniques. 2. The use of multiple teaching methods - It could be combined with a multi-media class to play related technical teaching videos, guide students to read related knowledge, analyze the principles of table tennis techniques, and form an understanding of the importance of correct movement techniques. They could also adopt the cooperative learning method of different groups. The students with better skills could help the students with poor foundation. Through on-site lectures, introductions of playing experience, sparring, and other forms, they could improve the overall table tennis skills and ability, and at the same time cultivate the spirit of mutual help and learning, unity and cooperation. In addition, because the table tennis ball is small, fast, and variable, teachers should pay attention to the practice of footwork and table tennis special quality in teaching, so as to improve the students 'movements, reactions, movement speed, etc. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
Chapter 10 Analysis and Reflection of Teaching Materials
1. ** Main content and application ** - This chapter was mainly about axis-symmetries and isosceles. Axially symmetrical figures were introduced from real-life figures. They had a harmonious symmetrical beauty and were widely used in life, production, science and technology, such as the symmetrical beauty of buildings, houses, cosmic celestial bodies, mirrors in daily life, and the reflection of cosmic planets. Students were required to learn about the basic properties of axial-symmetries, and to be able to appreciate and experience the wide application of axial-symmetries in real life. They were also able to use axial-symmetries to explore the properties of an isosceles-triangle. 2. ** Reasoning ability training ** - In this chapter, he continued to combine reasonable reasoning and deductive reasoning. On the basis of the students 'understanding of mathematical reasoning, let them try to make mathematical reasoning for some relatively simple mathematical problems. 3. ** Teaching time and class allocation ** - The teaching time for this chapter was 10 lessons, and the specific allocation was as follows: " 10.1 Axially Symmetries in Life " 1 lesson;" 10.2 Understanding Axially Symmetries " 4 lessons;" 10.3 Isoscolic Triangles " 3 lessons; and " Review " 2 lessons. 4. ** Knowledge Network ** - It included axis-symmetrical figures, the distance between the point on the vertical bisecting line of a line segment and the two ends of the line segment, the distance between the point on the angle bisecting line and the two sides of the angle, the knowledge of two figures about straight line symmetrical, isosceles triangle, equal-sided triangle, equal-sided equal-sided angle, equal-sided equal-sided edge, and so on. 5. ** Reflection and summary ** - In the process of teaching, students could be guided to observe more axis-symmetrical phenomena in life and enhance their understanding of axis-symmetrical and isosceles-triangle properties. At the same time, in terms of the cultivation of reasoning ability, more examples could be added to allow students to gradually master the application of plausible reasoning and deductive reasoning. In terms of class allocation, it was necessary to ensure that there was sufficient teaching time for key content such as the understanding of axis-symmetrical and isosceles-triangle so that students could better grasp the knowledge. Moreover, in the construction of the knowledge network, students should be guided to sort out the connections between the various knowledge points, such as the relationship between the properties of the isosceles triangle and the axial-symmetrical properties. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis and Reflection on the Introduction of Biology Teaching in Class
There were several problems in the introduction of biology teaching: ** 1. Introduction Form ** 1. ** Single Form ** - At present, most biology classes used the traditional direct introduction method. No matter what the content of the new lesson was, this single method was used. This would cause students to develop aesthetic fatigue, and over time, they would also have conflicting emotions. For example, he always started the lesson with a simple statement of the content of the new lesson. There was a lack of change. - This single introduction method did not match the content of the new lesson well, resulting in the teacher's classroom teaching efficiency and teaching quality being greatly reduced. The students 'interest in biology gradually decreased, and it was difficult to consolidate their biology foundation. 2. ** Lacking in variety ** - There were not many ways of introduction, such as introduction according to stories, introduction according to review, introduction according to speech, introduction according to oral composition, introduction according to setting situations, introduction according to playing music, introduction according to playing movie clips, etc. ** 2. Purpose of import ** 1. ** Formless ** - Some teachers didn't recognize the specific goal of the introduction stage and only introduced it for the sake of introduction. This would waste precious classroom time and mislead students to learn new lessons, ultimately leading to a teaching effect that was twice the effort and half the effort. In order to improve the biology classroom introduction, we need to follow the four principles of conciseness, liveliness, purposefulness, and multi-interest. Teachers could " question " the teaching content and construct " question strings " to stimulate students 'interest in independent learning. They could also introduce biology classes into life like some schools, connecting common biological phenomena in life to improve students' enthusiasm for learning. At the same time, innovative methods such as argumentation-based teaching could be introduced into the classroom to improve the effectiveness of teaching and cultivate students 'scientific thinking ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Compared to the original textbook, the Grade One biology textbook had changed from three books to two. The original textbook included " High School Volume One,"" High School Volume Two," and " High School Volume Three." The new textbook was the compulsory " Molecules and Cell " and " Heredity and Evolution ". There were a total of nine chapters, of which the compulsory one had five chapters and the compulsory two had four chapters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
An Analysis of the Evaluation of Biology Teaching in Senior High School
Take an open class on "Biological Species and Protection" at Guangya Middle School in Guangdong as an example. This was an open class for a new teacher. There were some developments in the class. From the teaching materials, this part of the content was simple and easy to obtain. The teacher had a good grasp of the content of the teaching materials. In the process of preparing lessons, the new teaching reform requires the teacher to change the mode of teaching to the end, so that students can change from passively accepting knowledge to actively acquiring knowledge, which involves the application of the concept of developmental teaching evaluation. For example, during the discussion of this public lecture, his colleague suggested that some of the content should be taught by students. This new model of allowing students to participate in teaching was to explore how to fully reflect the student's dominant position. It was also the embodiment of the concept of developmental teaching evaluation in the design of teaching models. Teachers changed from the traditional full-power teaching mode to trying to let students participate in part of the content. This change reflected the adjustment of the teaching process according to the needs of the students 'main position in order to achieve better teaching results and conform to the concept of developmental teaching evaluation. During the preparation process of the open class, the teacher constantly thought about how to change the teaching method to adapt to the spirit of the new curriculum reform. This series of thoughts and attempts were the embodiment of the development of teaching evaluation in the actual preparation process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis and Reflection on the Teaching Materials of National Unity in the Nurseries
The following is an analysis and reflection on the national unity teaching material in kindergarten: ** I. Teaching Materials and Forms ** 1. ** Multi-cultural elements integrated into the content ** - Some of them incorporated ethnic culture into their teaching materials. For example, a kindergarten in Wenshan Prefecture compiled a textbook for ethnic education, which covered the fields of society, health, science, art, language, and so on. Through social activities such as "We are all a family", musical rhythms such as "Flower Mountain Music" and "Paper Horse Dance", singing activities such as "Mantis Song", sports games such as "Cockfight", and art activities such as "Beautiful Miao Dress", children were allowed to experience and appreciate the culture of ethnic minorities in Wenshan in the five fields of teaching. This kind of content design could allow children to come into contact with the unique elements of different ethnic cultures in a variety of activities, from social interaction concepts to art, sports, and many other aspects. They could feel the charm of ethnic culture in all aspects. - The fourth kindergarten in Wangqing County had built four curriculum systems: folk games, folk art, festivals and solar terms, and children's homonyms, which permeated the consciousness of the Chinese community. These curriculum systems contained rich ethnic cultural implications. For example, folk art courses could allow children to come into contact with the unique art forms of different ethnic groups, and festival and solar term courses could allow children to understand the traditional festivals and customs of various ethnic groups. 2. ** The format is in line with the learning characteristics of children ** - The compilation of kindergarten teaching materials focused on combining the characteristics of pre-school children learning in games. For example, Wenshan Prefecture's kindergarten integrated the awareness of national unity into games, artistic creation, and other forms of activities, so that children could learn national cultural knowledge in a relaxed and happy atmosphere. The fourth kindergarten of Wangqing County adopted the educational environment of mixed classes and mixed ages, as well as the interaction between teachers and children. Mixed classes in the indoor common area and outdoor games were used to mix ages. This form helped to strengthen the communication between children and was also conducive to the spread of national unity awareness in children's interaction, which met the needs of children's social learning and growth. - There were also some children's self-made teaching materials for national unity, such as the March 3 Colored Book. It was presented in a cartoon style, in A4, A3, 8K, and other size suitable for children. It was colorful and frameless, which could attract children's attention. Moreover, the handwritten report could also allow children to learn about national unity through hands-on operations. ** 2. Teaching material objectives and effects ** 1. ** Clear and proactive goal ** - The goal of the national unity teaching materials in the kindergarten was to cultivate children's sense of identity with the national culture. In the hearts of children, they would subtly and silently sprout the feelings of loving their hometown, loving their motherland, and loving China. For example, the curriculum system of the fourth kindergarten in Wangqing County would build the consciousness of the Chinese community into the curriculum, integrate it into the activities, nourish the childlike heart, and cultivate the quality of children's pro-tradition, healthy physique, clear etiquette, joy of learning, and good communication. This showed that the national unity teaching materials in the kindergarten aimed at the comprehensive development of children and the education of national identity, and had a positive educational orientation. 2. ** The effect is gradually showing ** - In actual teaching, children showed different positive changes from small class to large class. For example, the teacher of the fourth kindergarten in Wangqing County mentioned that in the process of national unity and progress education, children had different growth at different stages, which indicated that teaching materials and related educational activities played a positive role in the growth of children, and children gradually improved in national unity awareness and cultural accomplishment. ** 3. Reflection and direction for improvement ** 1. ** Balance of depth and breadth ** - Although the current national unity teaching materials in kindergarten were diverse in content, they might need to be further balanced in terms of depth and breadth. For example, the introduction of national culture might be more superficial in terms of art, games, etc., and the deeper content behind some national cultures, such as history and religious beliefs, might be less involved. Under the premise of ensuring the children's understanding ability, some in-depth content could be added to broaden the children's national cultural vision. 2. ** Harmonization of Personalization and Universality ** - The textbooks in different regions might be compiled according to the local ethnic characteristics, but there might be shortcomings in terms of universal application. For example, some teaching materials might over-emphasize the local culture and lack a comprehensive introduction to the culture of other ethnic groups in the country. In the compilation of teaching materials, the relationship between local ethnic cultures and the cultures of all ethnic groups in the country could be better coordinated, so that children could not only have a deep understanding of local ethnic cultures, but also have a broad understanding of other ethnic cultures. 3. ** Perfection of the evaluation system ** - The evaluation system for the teaching effect of the national unity teaching materials in the kindergarten might not be perfect enough. Although there were positive changes in children's behavior and consciousness as a reflection of teaching results, there was a lack of a systematic and quantitative evaluation standard. A more scientific and reasonable evaluation system could be established. For example, through the quantitative evaluation of children's cultural knowledge, national unity awareness, cross-cultural communication ability, etc., in order to better improve the content of teaching materials and teaching methods. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis and Reflection on Teaching Materials of English Writing Class
The following are some of the main points of the analysis and reflection of the teaching materials for the English writing class: ** I. Analysis of Teaching Materials ** 1. ** Description ** - For example, the content structure of the teaching material of Oxforddiscover was systematic. It had 18 units and 9 topics, and each topic contained two articles. In the writing specialization, there was special writing training for these nine topics. This kind of structure helps to carry out writing teaching step by step according to the topic, so that students can accumulate relevant writing materials and skills under different topics. - For high school English textbooks, in the analysis of the writing lesson plan, it was necessary to pay attention to the setting of the essay topic for each unit in the textbook and the writing requirements in the accompanying exercises. For example, some teaching materials might first read the article in the unit study, and then guide the students to write through reading, such as learning the idea, structure, and some expressions of writing from the article. 2. [Skill Guidance] - In the teaching materials of Oxforddiscover, the writing specialization was better at guiding students from reading to writing. It taught students how to think. Through drawing mind maps and writing outlines, students could build their own writing framework. Finally, it also guided students on how to modify drafts. This kind of step-by-step guidance on writing skills helps to improve students 'writing ability. - In the high school English textbook, there might be some writing points, outlines, methods, and so on. For example, in some units, there will be some usable sentence patterns. For example, in writing describing opinions, there will be "I do not agree with..." I think I should be allowed to.. I would like to..”These sentence patterns are important material for students to write. When the teacher analyses the teaching plan, he needs to know how to guide the students to use these sentence patterns for effective writing. 3. ** Connection with other knowledge ** - In the textbook of Oxforddiscover, it was related to natural pronunciation and grammar. For example, the content of the Spelling specialization not only involved the pronunciation rules of letters in natural pronunciation, but also grammar related content such as alphabets, which helped students accurately spell words in writing and use the correct grammar structure. - In high school English textbooks, writing was also closely related to other knowledge and skills. For example, students tend to make sentences in Chinese, which involves the correct use of English grammar and vocabulary, as well as the cultivation of English language habits. The reading articles in the textbooks could provide language input for writing, help students learn English expression habits, and avoid the emergence of Chinglish. ** 2. Reflection ** 1. ** Teaching Effect ** - Judging from the students 'writing results, there were many problems. In the final examination, the average score for writing may be lower, such as only 6 - 7 (15 points in total). Many students had serious shortcomings in their writing. Some students only wrote a few words (or even copied them from the questions), while others had a lot of sentence errors and even wrote nothing. This reflected the problems in the current writing teaching. It could be that the teaching methods did not effectively let students master writing skills, or that they did not pay enough attention to the cultivation of students 'writing ability. - In daily teaching, although teachers spend a lot of time explaining, guiding, and classroom training on the composition of each unit, such as explaining the main points, outlines, and methods of writing, the effect is not ideal, especially for students with learning difficulties. This might be because there was too much teaching content, and students could not fully absorb and apply this writing knowledge when they were in junior high school or high school. 2. ** Student Questions ** - The students themselves were afraid of learning English, especially writing. Some students thought that English was difficult since they had poor grades in primary school. In the higher grades, as the content of the study increased and became more difficult, this mentality became more serious. They had the idea of giving up, which was a great obstacle to writing teaching. - Students are prone to making various mistakes in their writing, such as using Chinese to make sentences, making many grammar mistakes, and having poor ability to plan the layout and cohesion of the article. When the outline was translated into English, it would be translated word by word according to the language thinking, without considering the integrity and legibility of the sentence. This reflected that the students had not really mastered the way of thinking and basic skills of English writing. 3. ** Directions for Teaching and Learning ** - Teachers could learn from the guidance method in the teaching materials like the Oxford discover from reading to writing, and pay more attention to cultivating students 'writing thinking in the design of teaching plans. For example, after explaining the reading of the article, guide the students to analyze the structure of the article, language expression, etc., and then let the students imitate the writing. - Teachers could adopt a more targeted approach to students 'mistakes. For example, he would show the students 'typical mistakes and let the students find the mistakes and correct them together. At the same time, he would give the key words and key structures on the blackboard to gradually guide the students to perfect the sentences and cultivate their correct writing habits. In addition, the teaching content should be arranged reasonably to avoid too much and too complicated content, so that students could better digest and absorb the knowledge related to writing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis of Biology Teaching in Junior High School under the Internet
In the context of the Internet, junior high school biology teaching had many characteristics and changes: ** I. Teaching model innovation ** 1. ** Pre-reading session ** - With the help of the smart classroom to push the micro-class video to assist in the preparation, teachers could understand the students 'preparation situation and problems through data feedback and message boards. Students could discuss online to form a learning community. For example, in the teaching of Understanding the Biosphere, students actively asked questions on the message board after pushing the relevant micro-class. 2. ** Class Introduction ** - Teachers use the wisdom classroom to construct life situations, break through the limitations of time and space in the classroom, and let the students devote themselves to learning. For example, in the teaching of "The Sprouting of Seeds," a "7-Day Observation Diary of Mung Bean Seeds" was arranged. Students used tablets to take photos and upload them to connect life and knowledge. 3. ** Class activity segment ** - The smart classroom was rich in interaction forms, such as answering questions and random roll calls to increase students 'attention and participation. Group discussion missions in the 7th grade biology book "Human nutrition" could be uploaded to the big screen for sharing. - In terms of biological experiment teaching, teachers could display the experiment process through the physical booth of the tablet terminal. The experiments that were difficult to complete in the classroom could be operated using the virtual experiment booth. For example, the experiment of the blood type identification in the Transportation of Materials in the Human Body could be simulated by the students in the virtual laboratory. 4. ** Class feedback segment ** - In the smart classroom environment, the teacher arranged the whole class to answer questions, the students used the tablet terminal to answer the questions and submit them, and the teacher grasped the learning situation through intelligent marking and big data statistics and analysis to promote in-depth learning in the classroom. 5. ** Homework arrangement and evaluation segment ** - In addition to paper assignments, various forms of assignments such as micro-class review and virtual experiments could be arranged to improve the fun and targeting of assignments. In the evaluation class, big data was used to analyze the test situation, and the exercises were customized according to the students 'weaknesses, generating a customized study manual. ** 2. Change in lesson preparation ** 1. ** Preparing lesson information ** - Teachers could upload their coursewares, microclasses, and lesson plans to online platforms (such as QQ groups, WeChat groups, school public emails, etc.) to realize information sharing and teaching experience exchange, make up for the lack of offline lesson preparation, obtain lesson preparation materials anytime and anywhere, improve the humanization of lesson plans, integrate resources, promote the reform of traditional education methods, and improve the teaching level of teachers. ** 3. Teaching Concept Creation ** 1. ** Host and Resources ** - To ensure that students are the main body of learning and give full play to the role of experiments. "Internet +" provided teachers with rich teaching resources, improved teachers 'ability to apply information, made experimental teaching more flexible, and allowed students to learn theoretical knowledge in the process of hands-on operation. 2. ** Flipping the classroom ** - Breaking the traditional teaching method, using the "Internet +" technology to create a flipping classroom, realizing the combination of online and offline education. For example, in the teaching of "Biosphere", students 'subjective initiative was improved through micro-class production. ** IV. Promotion of Happiness Education ** 1. ** Teacher's Happiness Increases ** - In the context of the Internet, the happiness education in junior high school biology teaching first focused on the teacher's happiness. Teachers could organize students to participate in biology learning activities in groups to improve their own teaching happiness. At the same time, the school could organize professional training for teachers to let teachers feel happiness in the process of improving their knowledge level and teaching ability, thus promoting the teaching of biology happiness. 2. ** Student Happiness Experience ** - Biology teaching was integrated into happiness education, focusing on biological knowledge, allowing students to experience the wonders of nature in the exploration of biological knowledge, and gain exploration achievements and happiness. For example, in the aspect of cherishing life education, courses such as refusing alcohol and tobacco, staying away from drugs, and paying attention to health were set up. Students were allowed to participate in learning through a variety of methods (discussion, reading materials, etc.), and the results of the survey were published in small groups and protective measures were popularized. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
