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>

High school biology light reaction dark reaction video lecture teaching
The following is a suggestion for the teaching content of the high school biological light reaction and dark reaction video lecture: ** 1. Light reaction part ** 1. ** Opening Introduction ** - The importance of photosynthesis as a whole could be emphasized. It was the source of most biological energy and organic matter on Earth, and the light reaction was the critical initial stage of photosynthesis. - Show some natural phenomena, such as green plants growing luxuriantly under the sun, etc., to arouse students 'interest and induce light reactions. 2. ** Light reaction site ** - Illustrate the structure of the plastids through animations or pictures, emphasizing the thylakoid membrane, and tell the students that this is where the light reaction takes place. It could be likened to a specialized "light energy conversion factory." - The thylakoid membrane had important substances such as photosynthesis, which were the key factors for the light reaction. 3. ** Light reaction conditions ** - It was clearly stated that the light reaction required light, photosynthesizing dye, and the three main conditions for the reaction. - As for light, explain the effects of light of different wave-lengths on photosynthesis, and show the absorption spectrum of the photosynthesizing dye, indicating that the main absorption of the red light and blue-purple light by the chopstick. - As for the photosynthesizing dye, the structural characteristics and functional differences of the two could be described in detail. For example, the light energy absorbed by the dye could be converted into energy, while the light energy absorbed by the dye could be converted into energy. Caroteroids could help to absorb light energy and protect the dye. - Mentioning the role of the catalyst, he emphasized the high efficiency and specialty of the biochemical reaction. In the light reaction, the catalyst played a role in promoting the transformation of various substances. 4. ** Light reaction, substance change ** - The photodecomposition process of water was shown in an animated form. Water was decomposed into oxygen, hydrogen ions (H) and electrons (e) under the action of light energy and microorganisms. It was emphasized that oxygen was an important product of the light reaction and would be released into the external environment. - Then, it showed the process of hydrogen ions forming a photon concentration grads in the thylakoid cavity, driving AAD and Pi to synthesize ATP. This process emphasized the conversion of energy, that is, the conversion of light energy into chemical energy stored in ATP. - At the same time, it showed the process of hydrogen ions combining with NRIDP2 to form NRIDPM ([H]) outside the thylakoid body. It explained that NRIDPM was also a substance that carried energy, and it had reducing properties, which would play an important role in the dark reaction. 5. ** Light reaction energy change ** - The energy change in the light reaction was summarized. After the light energy was absorbed by the photosynthesizing dye, it was converted into chemical energy in the form of bound bound This process could be represented by a diagram of energy flow, starting from light energy and flowing to the chemical energy of Ang P and Ang P. ** 2. Dark reaction part ** 1. ** Dark reaction site ** - He showed a picture of the structure of the plastids and pointed out that the place where the dark reaction occurred was the plastids matrix, which was different from the thylakoid membrane where the light reaction occurred. It could be likened to a "chemical synthesis workshop." - It was emphasized that although the dark reaction had the word "dark" in its name, it did not mean that it could only be carried out in the dark. As long as there was a light reaction to provide substances such as Ang, Phosphatease, and carbon dioxide, it could also be carried out normally under light conditions. 2. ** Dark Reaction Condition ** - The main emphasis was on the need for ATP-Na, ADMPH, carbon dioxide, and a variety of membranes. - It explained that Ang-2 and Ang-3 were energy and reducing agents provided by the light reaction, carbon dioxide was the raw material for the dark reaction, and the protein was used to catalyze the various chemical reaction steps in the dark reaction. 3. ** Dark Reaction Matter Change ** - Illustrate the Calvin Cycle process with an animation. The first step was to fix carbon dioxide. Under the catalyst of the catalyst, carbon dioxide combined with a five-carbon compound (C5, RuBG) to form two three-carbon compounds (C3). - Then, the reduction process of C3 was demonstrated. C3 was reduced to organic substances such as sugar (CH <anno data-annotation-id ="0000004 - 4444 - 4444-a888 - 8888888888844"> O </anno>) with the energy provided by ATP-bound and the hydrogen provided by ADMPH. At the same time, some C3 was regenerated into C5 after a series of changes. It was emphasized that this was a circular process, and the regeneration of C5 ensured the continuation of the dark reaction. 4. ** Dark reaction energy change ** - This meant that the energy change in the dark reaction was the conversion of chemical energy in the ATPs into chemical energy in the organic matter. In this process, the energy was stored for plant growth, development, and other life activities. ** 3. The relationship between light reaction and dark reaction ** 1. ** Material Connection ** - Make a table or chart to compare the material changes in the light reaction and the dark reaction, and clearly indicate that the light reaction provides the dark reaction with ATP-P, and the dark reaction provides the light reaction with AADP-P, Pi, and ADP-P. - For example, arrows were used to indicate the direction of the flow of matter. The arrows of Ang, Ang, and Ang were used to indicate the flow of matter from the light reaction to the dark reaction, and the arrows of Ang, Ang, and Ang. 2. ** Energy connection ** - Once again, the light reaction converted light energy into chemical energy (the chemical energy in the form of ATPs and ADPs), and the dark reaction used this chemical energy to synthesize organic matter and store energy. The two formed a continuous process of energy transfer and conversion. - This connection could be visualized using a diagram of energy flow. It started with light energy, converted into chemical energy through light reactions, and then stored in organic matter through dark reactions. ** 4. Summing Up and Consolidating Practice ** 1. ** Summing Up ** - The location, conditions, material changes, and energy changes of the light reaction and dark reaction were summarized in a comprehensive manner. The characteristics and connections of the two reactions were summarized in concise language. - Students could review and construct a process diagram of the light and dark reactions in their minds. Then, they could be asked to describe the process to test the student's mastery. 2. ** Consolidating Practice ** - Give some practice questions related to light and dark reactions. For example, when the light is suddenly stopped or the carbon dioxide supply is suddenly stopped, how will the content of substances in the light and dark reactions (such as C3, C5, Ang, ADPM, etc.) change? Ask the students to analyze the reasons. - Some practical experimental phenomena could be given, such as measuring the amount of oxygen released and carbon dioxide absorbed by plants under different light intensity, so that students could judge the progress of light and dark reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
