Home Circuit Teaching Plan and Teaching Reflection
Home Circuit Teaching Plan: - ** Teaching objective **: - ** Knowledge goal **: Understand and master the composition of household circuits, understand the concept of live wire and neutral wire, understand the function of fuse, understand the structure and usage of sockets and household appliances, and test pen. - [Ability Target: Able to solve simple household electrical problems.] - ** Emotional goal **: Set up a theory and connect it with reality. - ** Teaching process **: - ** Question Introduction **: By listing the common phenomena in household electricity consumption, such as the electrical appliances stopping working at the same time or the damage of a single electrical device does not affect other electrical appliances, the topic of household circuit composition is introduced. - ** New lesson **: - ** Household line **: The household line has two poles: live line and neutral line. The home circuit used alternating current. The neutral line was grounded and had no voltage with the earth. There was a 220V voltage between the live line and the neutral line. The electrical appliances were connected in parallel between the live line and the neutral line. The failure of one branch would not affect the work of other branches. - ** Fuse **: Since the electrical appliances are connected in parallel, the more electrical appliances are used at the same time, the greater the main current. There was a current limit for the household line, and exceeding it would cause the wire to heat up and cause danger. The fuse was made of lead-stibine alloy with high electrical resistance and low melting point. When the main circuit current was too high, the fuse would blow and cut off the main circuit current to protect the circuit. Do not replace the thick fuse with iron wire or copper wire. - ** socket **: The power jack on the wall is the socket. The two-hole socket is connected to the live wire and the neutral wire. The three-hole socket is connected to the live wire, the neutral wire, and the ground. Reflection on Home Circuit Teaching: - ** Reflection 1**: Take the classroom participation of the home circuit as the guiding ideology of learning. Students become the main body, and teachers are the schemers. The students will learn in groups to improve their social practice ability. Teachers guided students as equals. The core of the curriculum was to change the way of learning, emphasizing active inquiry learning, learning knowledge through group cooperation, strengthening the sense of cooperation, strengthening the learning effect in various ways, creating a good communication atmosphere, and introducing appropriate videos to arouse the enthusiasm of students. - ** Reflection 2**: Design inquisitive questions to raise students 'interest, help them understand basic knowledge, weaken the imparting of knowledge points, and strengthen the exploration of difficult problems. Using demonstration experiments and other intuitive teaching methods, such as through the question room and home circuit composition, using video coursewares, text, pictures, videos, objects, etc. to let students grasp knowledge in the process of observation and reduce the difficulty of understanding. - ** Reflection 3**: When teaching home circuits, focus on the use of the test pen, switch and socket connection, and other key points to carry out teaching. By playing the electric shock video, the new lesson was introduced to reflect the concept of "moving from life to physics" and arouse interest in learning. Let the students go on stage to find the line of fire and cultivate their hands-on skills, expression skills, and courage. This paper analyzed the reason why the fuse was connected to the live wire and compared it with the situation of connecting to the neutral line. It used the physical map to analyze the middle hole of the three-hole socket to be grounded, reflecting the idea of "physics comes from life and goes to life" and paying attention to cultivating students 'scientific inquiry ability.

From the beginning of the art of peace
I'm not sure what you mean by "starting from the Taiping technique". If you want to ask about the origin of Taiping Yaoshu, in the Romance of the Three Kingdoms, it was given to Zhang Jiao by the old immortal of Nanhua. Zhang Jiao was originally an unranked scholar. When he went to the mountains to pick herbs, he met the old immortal of Nanhua. The old immortal of Nanhua gave him three volumes of the Heavenly Book called "The Art of Peace" and told him that he had to preach the book on behalf of heaven and save the world. If he had any disloyalty, he would be punished. After Zhang Jiao got the book, he practiced it day and night and mastered the ability to summon the wind and rain. He was known as the "Taoist of Peace". Later, he gathered a crowd to make trouble and triggered the Yellow Turban Rebellion at the end of the Han Dynasty. If your question has other meanings, please be more specific.
