Junior high school special color material teaching reflection summary how to write
The following is an example of a reflection summary of special color substances in junior high school: ** 1. Teaching content ** 1. ** Knowledge Points Covered ** - When teaching special color substances, it basically covered the special colors of solid, solution, precipitations, and gases that were common in junior high school chemistry. For example, it explained in detail the black solid (such as copper dioxide, Manganese dioxide, etc.), blue solution (solution containing copper ions), reddish-brown deposit (iron dioxide), etc. However, some of the colors of substances that were not common but were involved in some of the expansion questions were not explained in depth, such as the special colors of some transition metal compounds. This may cause students to lack sufficient knowledge when facing difficult comprehensive questions. 2. ** Control the difficulty of the content ** - For most students, the knowledge of the colors of common substances was not complicated. However, in the teaching process, when the color of the substance was combined with the nature of the substance, the reaction phenomenon, and the identification method, some students had difficulty understanding. For example, when explaining the use of color to identify substances, it involved the identification of a variety of substances, such as the identification of cupric copper, salt, and salt solid. The students could not quickly grasp the idea of comprehensive consideration of color and other properties (such as dissolution, reaction with other reagents, etc.). This meant that the transition of content difficulty needed to be more gradual. 3. ** Knowledge System ** - When constructing the knowledge system of special color substances, although it was explained according to the classification of solid, solution, precipitations, and gases, the connection between the various parts was not emphasized enough. For example, when explaining the color of a solution, there was no sufficient connection with the substance that could produce the color or solid. This caused the students to lack an overall thinking framework when memorizing and applying knowledge. They were more likely to memorize the corresponding substances of various colors in isolation. ** 2. Teaching methods ** 1. ** Teaching Method Usage ** - The traditional teaching method was used in combination with the example method. When explaining the color of substances, the students could deepen their understanding by showing pictures and listing examples of substances in chemical equations. However, this kind of teaching method was relatively simple and lacked interaction and fun. As for the abstract relationship between color and material structure (such as why copper ion solution was blue), there was a lack of intuitive models or animations, causing students to only memorize it, and it was difficult to truly understand its internal principles. 2. ** Experimental Teaching ** - In the teaching of special color substances, the experimental teaching was relatively weak. Although the formation reaction of the blue deposit (reaction of copper sulfuric acid and soda) was mentioned in the explanation of the color of the deposit, there was no demonstration experiment or student experiment in the classroom. If the students could observe the process of the formation of copper dioxide from the solution, they would have a deeper memory and understanding of the blue deposit. At the same time, it could also improve the students 'ability to observe the phenomenon of chemical experiments and their interest in chemistry. 3. ** Guide students to learn ** - When guiding students to learn special color substances, they paid attention to letting students memorize them, but there were some shortcomings in the methods of cultivating students 'self-induction and analogy learning. For example, students could be guided to conclude the rules of the color of different ion solutions according to the types of metal ions, or they could be asked to simulate the possible similarities in the properties of substances with similar colors. However, in actual teaching, there was not enough attention to the guidance of these learning methods. ** 3. Students 'learning situation ** 1. [Learning feedback] - Through classroom questions and homework, it was found that the students 'memory of special color substances was uneven. Some students could accurately remember the colors of common substances, but they had difficulty using this knowledge to solve practical problems such as substance identification and inference questions. Some students couldn't even remember the basic colors of materials accurately, which reflected that there was no hierarchical teaching and individual tutoring for students with different learning abilities. 2. ** Student interests ** - From the classroom performance, when explaining special color substances, the students 'interest was mainly focused on the substances that were more colorful or closely related to life (such as the purple-red color of potassium Permanganate). For some monotonous or theoretical content (such as dry ice in colorless substances), students were less interested and easily distracted. This also suggested that the organization and presentation of teaching content needed to pay more attention to fun and attractiveness. ** 4. Enhancement measures ** 1. ** Upgrade teaching content ** - He added some knowledge about special color substances that might be involved in the expansion questions, and at the same time, he strengthened the connection between the various parts of the knowledge. For example, creating a mind map or a knowledge framework map would combine special color substances with chemical equations, reaction types, substance identification, and other knowledge to allow students to form a more complete knowledge system. 2. ** To improve teaching methods ** - To increase the variety of teaching methods, in addition to the traditional teaching method and the example method, they could introduce multi-media resources, such as animation to demonstrate the relationship between the structure and color of materials, and use virtual laboratory software to let students carry out interaction learning such as material identification. To strengthen the experimental teaching, design some simple and interesting experiments on special color substances, such as self-made copper sulfuric acid crystals (blue crystals), etc., so that students can learn and remember in the experiment. At the same time, they would focus on cultivating the students 'learning methods and guide them to make their own conclusions. For example, they would let the students make memory cards with special colors or hand-copied reports that summarized the rules. 3. ** Pay attention to the individual differences of students ** - Students were taught according to their classroom performance and homework. For students with learning difficulties, additional tutoring and targeted exercises were provided, such as memorizing the formula for making special color substances. For students who had the ability to learn, some expansive learning materials could be provided, such as questions involving special color substances in chemistry competitions or related scientific research results, to meet the learning needs of students at different levels. At the same time, during the teaching process, pay attention to improving the interest of the teaching content, combining it with real life or chemical history stories, etc., to increase students 'interest in learning special color substances.

The meaning of crane cry
"Crane Cry" had many meanings. From the Book of Songs, Xiaoya, Crane's Cry, the "crane's cry" in the poem depicted the scene of cranes chirping in the swamp. This image, together with the images of fish, trees, stones, etc., constructed a rich meaning. The poem was regarded as a "hidden poem" to express the idea of recruiting talents for the country. The crane's cry in the poem was heard in the wild or in the sky. The "crane's cry" here may be a metaphor for the wise man's fame despite his seclusion. In China guqin music, there was also the song " The Crane Cry in the Nine Gao," but the original song did not have any meaning analysis. In addition, in the context of reality," crane cry " referred to the actions or sounds of cranes chirping. "The Crane Drinks the Spring Breeze" is equally exciting.
