Introducing new lessons is an important part of classroom teaching. “A good start is half the battle.†At the beginning of the lesson, the students' attention is quickly concentrated, and their thoughts are brought into a specific learning situation, which plays a crucial role in the success or failure of a class. Using the audio-visual media to introduce new lessons can effectively open the gates of students' thinking, stimulate associations, stimulate inquiry, and lay the foundation for the success of a class. First, stimulate interest, initiate cognition Interest is the best teacher. Creating a situation and making students quickly enter the best learning state is a powerful measure to stimulate interest in learning, to sprout desires, and to initiate cognition. For example, when teaching the "Seven Puzzles" class, in order to create a novelty in the beginning of the class, start thinking; at the same time, to spread the teaching difficulties, I have produced a lot of vivid, color-clear graphics made with jigsaw puzzles. At this time, ask: "Do you think these pictures are beautiful? Do you want to spell out the same or better graphics than them?" to fully mobilize the students' enthusiasm. This kind of teaching introduction not only breaks through the difficulties in the process of concept formation, but also stimulates students' cognitive interest and receives the teaching effect with half the effort. Second, set aside doubts and stimulate thinking "Learning from thinking, thinking about doubts." Thinking generally begins with the problem. When introducing a new lesson, you can create a “problem of the problem†and ask questions to arouse the students’ intentional attention and positive thinking. Third, set suspense, guide exploration Suspense can create a state of eager anticipation, with a strong temptation, and can stimulate a strong interest in exploration and pursuit. This is a method that teachers often use to design and introduce new lessons. The suspense of setting should be characterized by “fineâ€, “new†and “oddâ€. In terms of skill, it should be “lead and issued†and “thinkingâ€. Fourth, create a situation, stimulate knowledge The introduction of the new situation in the contextual style is to melt the shape, the emotion, the environment and the science. Use music, projection, recording, video and other means to render the classroom atmosphere, providing students with a specific context to understand the textbook. For example, when a teacher teaches “meeting problemsâ€, in order to clear the learning obstacles, a situation is created: using activity slides to show students the meaning of the concepts of “simultaneous†and “oppositeâ€. Promote the search for new knowledge. 5. Use stories to inspire Lenovo In response to the psychological characteristics of primary school students who are interested in listening to interesting anecdotes, in the introduction of new lessons, appropriate introduction of stories, allegories, allusions, whispers, anecdotes, etc. related to the teaching content can help students develop thinking and enrich their associations. They are eager to invest in new knowledge and become curious as a strong interest in learning. Similarly, when I was teaching the "Seven Puzzles" class, I told them a story about the origin of the jigsaw puzzle: there was a man named Huang Bosi in the Song Dynasty who studied the geometric figures. He was hospitable and invented a 6-piece. The "banquet" made up of small tables - a small table for guests to eat. Later, some people improved it into a banquet of 7 tables. According to the number of people eating, the table was put into different shapes, for example, 3 people were put into triangles, 4 people were squared, and 6 people were squared... ...this is convenient for everyone and the atmosphere is better. Later, some people changed the banquet to only seven boards, and used it to make a toy. Because it is very clever and fun, people call it "seven puzzles." In the late Ming and early Qing dynasties, people in the palace often used it to celebrate festivals and entertainment, and put together a variety of auspicious patterns and words. The Palace Museum still preserves the tangrams at that time! In the 18th century, the jigsaw puzzles spread abroad, and immediately attracted great interest. Some foreigners played it all night long and called it "Tangtu", which means "Jigsaw from China." Students will be particularly interested in the beautiful graphics that have been prepared in advance using the tangrams. Of course, the form of import is much more than these types. The key is to master the rules of people, time and place, but no matter what method is used to introduce new courses, they should achieve good results in imparting knowledge, inspiring wisdom, and cultivating sentiment. It is lively and interesting, fascinating, concise, and targeted, trying to give students an aesthetic satisfaction. Product name:Bathroom Cleaner
