A year's plan starts with spring. But for the school, it is autumn. As soon as the school starts in autumn, the school has entered a new school year, the metabolism has been completed, a group of new teachers have taken up their jobs, and a group of freshmen have been promoted to higher schools. At this time, the most important thing for teachers is the first class, and what students want most is the first class. So, how to have a good first class? In my opinion, the key to the first class of high school chemistry is to design three wonderful appearances.

1. Design a beautiful appearance for yourself.

When teachers and students meet, the first impression is very important, because a good beginning is half the battle. Therefore, teachers must carefully design their own appearance and try to leave the deepest first impression on students.

Generally speaking, the first thing a teacher should pay attention to when he appears is his appearance. They must be clean and energetic. But appearances are not enough. They should also show their most outstanding teaching advantages and strive to win the respect and even admiration of students in the first class, so as to lay a good foundation for the future cooperation between teachers and students.

So, how to design the next appearance? The most important thing is to analyze your own advantages and tailor them according to your own characteristics. For example, some teachers, especially young teachers who have just graduated, have a good knowledge of English. You can design your own opening remarks in English, so that students can be interested in you and the subjects you teach from the envy of your fluent English. Some teachers, who are good at drawing, can draw a chemist's head, rocket launch or ceramic sketch in advance, and introduce the topic from a beautiful picture about the history of chemical development; Other teachers, if they write well, can write down their names or a sentence they want to share with the students on the blackboard and enter the classroom teaching from the interaction with the students; If there are no other majors, we can design several fascinating experiments from the characteristics of the subject itself to stimulate students' interest in chemistry. These are all good designs.

There is such a teacher, whose handwriting is not so good, but whose computer level is good. He made a beautiful courseware with the computer and took the students to the multimedia classroom for the first class. Exquisite pictures, melodious music and rich content all opened their eyes and made them excited. He succeeded in fostering strengths and avoiding weaknesses, giving students the best first impression. Later in class, his shortcomings in writing also faded a lot.

2. Design a wonderful appearance for high school chemistry knowledge.

Although the teacher's own appearance is very important, it should not be the highlight of the first class, but just an introduction. The next thing to do is to design a wonderful appearance for high school chemistry knowledge.

Students from junior high school to senior high school have a gradual adaptation process, both psychologically and in learning methods. Then, in the first class, teachers should let students have a general understanding of high school chemistry knowledge, so that they can be psychologically prepared, and then consciously adjust their learning methods in the learning process to accelerate the completion of the adaptation process.

Senior high school chemistry knowledge is mainly divided into inorganic and organic parts, and inorganic chemistry is arranged with the periodic table of elements as the main line. For each group of main elements, the changing law of their properties is studied, and some theoretical knowledge is interspersed to form a three-dimensional network. Therefore, in order to let students have a preliminary understanding of this knowledge network, they must use some auxiliary teaching methods, such as multimedia courseware, videos, VCD discs and so on. And some pictures can be made by yourself if conditions are limited.

Don't design this network diagram too complicated, because students have just graduated from junior high school. At this point, their thinking characteristics are still concrete. If the chart design is too complicated, it is easy for students to get bored, but it is impossible to know a lot about high school chemistry, which is thankless.

When explaining this chemical knowledge network, we should also pay attention to the preliminary guidance of students' learning methods. For example, when learning the knowledge of elemental compounds, we should pay attention to the relationship between experimental phenomena and chemical properties and remember them flexibly; When learning the quantity of materials, we should grasp the concepts and formulas, use more brains and practice more, so as to avoid students taking too many detours in the process of exploring learning methods in the future.

3. Design a wonderful appearance for inquiry learning.

In the new round of curriculum reform, research-based learning is a bright spot, and judging from the college entrance examination in pilot areas in recent years, the status of research-based learning is becoming more and more important, but now students do not have this kind of practice in primary schools and junior high schools, so it is particularly important for teachers to design a wonderful appearance for research-based learning in the first class.

Inquiry learning is both a course and a learning method, so it is necessary to explain inquiry learning as a course and a learning method in the introduction of knowledge network in the previous part. In this part, we can focus on a topic as an example to illustrate how to carry out inquiry learning. This topic can be very small, mainly to let students understand what inquiry learning is. For example, you can say: you can find information to study the types and uses of paper, and you can investigate which kinds of paper are used the most in residents' lives and how much paper is consumed on average. You can go to the factory to understand the source and cost of raw materials for papermaking, the relationship between raw materials and paper, and you can also go to the paper mill to detect sewage discharge. Learn from many aspects, you can do many different topics, but also apply the knowledge and abilities of many disciplines. The whole process, that is, the process of learning in the form of research, includes common research methods such as consulting materials, investigation, experiment and data analysis, which is called inquiry learning. In this way, students have the most preliminary understanding of inquiry learning.

Finally, the teacher should strike while the iron is hot, prepare the relevant content in the speech and leave a small research topic. For example, from the perspective of chemical history, students can find the information about the influence of China's chemical development on the world's chemical development. The main purpose is to let students learn to use the Internet, libraries, etc. Obtain the required information; Students can also look for real materials or take photos of materials from life, and then edit them into a book, with the purpose of training students' communication skills, evidence collection ability and aesthetic ability.

In the first class of high school chemistry, if the above three appearances are wonderful, it is conceivable that the future chemistry teaching will smoothly embark on the road of harmonious cooperation between teachers and students, and most students will repay their teachers with the same wonderful appearances.
