"Celebrating Years 2" CCTV premiere

The following is the teaching reflection and teaching design ideas of the fifth unit of the third grade of Beijing Normal University: - ** Academic situation analysis **: Students 'concept of space is still in the initial stage of development. It is easy to confuse the concept of area and perimeter of the surface of an object. Some students have a vague understanding of area and perimeter, and it is difficult to distinguish between area units and length units. Therefore, teaching should let students touch and perceive the surface of the object more, experience the difference between the surface and the edge, and deepen the understanding of the meaning of "area". The unit of area was abstract. The teacher had to let the students use a certain part of the body or the surface of a familiar object as a reference to associate the unit of area with the size of the surface of the familiar object to make it concrete and vivid. - ** Teaching process assumption **: - Two methods to measure the area of a rectangular object in units of area can be presented. The first method was to use the area units to cover the rectangular shape without overlapping and without gaps, and the number of area units used was the number of rectangular areas. The second method was to use the area units to fill the length and width without densely covering the rectangular shape, and calculate the number of area units needed to fill the rectangular shape. Let the students choose their own method to measure the area of two rectangular shapes. Through observing the data, he found that the formula for calculating the rectangular area was " rectangular area = length x width " and verified it. From the special to the general induction, the formula was derived. For example,"length x width" was equal to "the number of length units contained in the length x the number of length units contained in the width", which was equal to "the number of rows x the number of rows". The square area calculation formula could be derived by analogy with the rectangular area formula. It could also be derived from the rectangular area formula by using the square as a special rectangular. - In teaching, students could be guided to do small research before class. Combined with the "non-linear" group cooperative learning mode, the traditional teaching mode could be broken, the teaching links could be simplified, the systematic explanation could be weakened, the process control could be weakened, and the students 'thinking could be activated. For example, it could allow students to study the basics of a rectangular shape, the concept of area, and the units of area. They could understand that the essence of area was the accumulation of the number of units of area. This process would also lay the foundation for the subsequent study of the surface area of a hexagon and a three-dimensional figure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Many reactions that require heating to occur are exothermic reactions, such as combustion reactions (such as carbon combustion: C+O <2>= CO <2>), metal and non-metal combination reactions (such as 2Na + Cl2 = 2NaCl2), etc. Although these reactions require heating to initiate the reaction, heat is released during the reaction. It was not easy to determine that the reaction was a thermal reaction just because it required heating. Instead, it was determined by comparing the energy absorbed and released before and after the reaction, or comparing the total bond energy of the reagent and the product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reproduction of the pike was rather special and required the participation of mussels. During reproduction, the female carp would wander around the mussel and stimulate the mussel to slowly open its shell with the help of water flow. Then, the female carp would insert the fallopian tube into the water hole of the mussel, allowing the eggs to enter it. At the same time, the male carp would produce sperm, which the mussel would inhale when breathing. The fertilized eggs would form in the body of the mussel, mostly attached to the gills of the mussel, and hatch into small fish after about 20 days. Had he not watched enough of Long Lovesickness 2?

To determine whether a Buddha statue was a cultural relic, one needed to identify it from many aspects. Firstly, it was the key to identifying the Buddha statue. If it was a modern imitation of a Buddha statue, it was generally not regarded as a cultural relic (cultural relics here generally referred to Buddha statues before the Republic of China). There were many factors to consider in order to distinguish between the real and the fake, and one could not make a one-sided judgment. Judging from the style of the era, the Buddha statues of different eras had different modeling features and decorative styles. For example, the Tang Dynasty Buddha statues were full of charm, the Song Dynasty was simple and natural, the Yuan Dynasty was rough, the Ming Dynasty was gentle and beautiful, and the Qing Dynasty was rigid. From a geographical point of view, the southern Buddha statues were gentle and gorgeous, while the northern Buddha statues were simple and rough. Professional appraisers usually first judge the era and style of the Buddha statue based on its modeling features and decorative styles, and then analyze it according to the artistic features of the Buddha statues stored in their brains. They had to observe all parts of the Buddha statue, including the back light and the Buddha seat. They could not only stop at the "shape" but also identify it from the "charm" height. It was relatively easy to achieve "shape" for new and fake Buddha statues, but it was more difficult to achieve "spirit". From the perspective of the divine personality and image of the Buddha statue, the divine personality of the Buddha statue was the name, religious content, and religious function of the Buddha statue. The image was the style that reflected these, which was also helpful in identifying authenticity. In terms of craftsmanship, during the Ming and Qing Dynasties, the Han Buddhist statues in the mainland were mostly gilded, and gilded. These techniques were also commonly used in Tibetan Buddhist statues made in the mainland. The traditional fire gold plating had a specific process. The gilding of the Buddha statues of the Ming and Qing Dynasties was thicker, and the color was yellow. There would be copper oxide-black soil from the inner tube after the gold fell off, and there would also be phenomena such as dust accumulation and patina. Modern imitation bronze Buddha statues were mostly plated, with a thin layer of gold, a bluish golden color, and unnatural peeling of gold at the exposed flesh. During the Yuan and Ming Dynasties, some Tibetan Buddha statues were painted red after being plated with gold. One could also identify the ancient Buddha statues by looking at the inscriptions on them. There were specific inscriptions on the statues of Yongle and Xuande palaces in the Ming Dynasty, and there were corresponding inscriptions on the statues of Buddha in the Qing Dynasty. In addition, it was also important to look at the remnants of the Buddha statue's inner wall. Under normal circumstances, there might be black carbon mud and gray cement in the concave part of the inner wall of the Buddha statue. If there were white quarts, white paste layers, or ash-like pink layers, it might be a modern imitation. The materials used to cast Buddha statues in modern times were different, so they would leave different remnants on the inner walls. Through the comprehensive judgment of these aspects, one could determine whether a Buddha statue was a cultural relic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
