Chemistry is a natural subject combining theory with practice. Senior high school chemistry learning is the necessary knowledge accumulation for students to enter the society, which lays the foundation for their future study and development. The following are the papers I collected to analyze the construction of high school chemistry efficient classroom for you. I hope you will like them.

Under the premise of the new curriculum reform, chemistry courses pay more and more attention to teaching methods and teaching processes. The ultimate goal of efficient classroom is to improve students' learning efficiency and lay the foundation for their future autonomous learning. To build an efficient chemistry class in senior high school, teachers should develop students' potential, cultivate students' habit of autonomous learning and promote their all-round development. Therefore, it is of great significance to attach importance to the basic activities of chemistry teaching and accumulate experience.

Keywords: new curriculum; High school chemistry; Efficient classroom

In high school chemistry teaching, teachers should reflect students' dominant position, and teachers are only guides, combining students' learning ability with chemistry experiments to help students solve problems better. Through experiments, students can consolidate and improve their chemical knowledge and level, improve their chemical ability in thinking, improve their innovative consciousness in thinking, and realize all-round and balanced development. This paper briefly analyzes how to build an efficient classroom.

First, the significance of constructing high school chemistry efficient classroom

Chemistry is a natural subject combining theory with practice. Chemistry learning in senior high school is an essential knowledge accumulation for students to enter the society, which lays the foundation for their future study and development. The concept of chemistry teaching under the new curriculum mainly focuses on students' autonomous learning and cooperative exploration. High school students have a certain physical and mental development, and have their own learning methods and ways of thinking. Therefore, teachers should innovate educational concepts, change classroom teaching mode, adapt to the needs of modern students' learning and development, and lay a good foundation for their future study and life.

Second, the construction of high school chemistry efficient classroom strategy

1. Cultivate students' interest in learning by combining the characteristics of chemistry.

Chemistry course is a basic subject in senior high school. In the process of teaching, teachers should design teaching mode according to the characteristics of chemistry subject to improve students' interest in learning. Teachers can use chemical experiments to guide students to form chemical concepts, so that students can improve their hands-on experimental ability, observation and exploration ability and innovative thinking ability while learning chemical knowledge. Chemical properties of metals? At present, teachers can teach from the perspective of life. With the rapid development of modern science and technology, many metal products, such as airplanes, ships, cars, coins, aluminum alloy doors and windows, are exposed in life, which can guide students to think about why these metals are used in modern science and technology, industrial production and daily life, and what their properties are, so that students can actively think and study, improve their interest in learning chemistry, and be willing to explore the knowledge of metal changes.

2. From the students' point of view, teacher-student interaction teaching.

In the teaching objectives of the new curriculum, we advocate the teaching concept of students' all-round development. Teachers are the guides of learning, and students are the subjects of learning. Therefore, no matter how good the teacher's teaching methods are, we should also let students participate in chemistry learning from the perspective of students. Only when students actively participate in classroom learning can the classroom atmosphere be activated, thus achieving the teaching purpose of chemistry classroom. Teachers can interact with students. Teachers should encourage students to actively participate in answering correct or incorrect questions, instead of making students a burden to answer questions. Through the question-and-answer mode, students are guided to learn, so that they can actively think about problems, become the masters of learning, and learn happily and independently. Like when talking? Carbon dioxide? At that time, teachers can ask students questions through questions and answers: What substances in life contain carbon dioxide? How can we study their properties? Guide students to actively participate in thinking. Through the exchange of students' thinking, they can pass on their own thinking answers to each other, thus stimulating students to think more.

3. Combining the theoretical knowledge of textbooks, open teaching

The teaching concept of the new curriculum is no longer a simple scripted and crammed education. It is better to teach people to fish than to teach people to fish? While teaching students how to acquire knowledge, teachers should also lay a good foundation for students' lifelong learning, instead of turning students into machines that can only test. In chemistry teaching, teachers can use textbook theory to guide students, so that students can carry out chemical experiments independently while ensuring safety. Students will certainly encounter more problems in the process of conducting their own chemical experiments than watching teachers demonstrate experiments at ordinary times. At this time, students will think about the answers to these questions by themselves. This open teaching mode allows students to actively participate in experimental learning and learn knowledge from it. It can also help students find more problems that they don't usually notice during the experiment, thus cultivating students' independent thinking ability.

For example, talking about? The reaction between metal and water? On the premise of ensuring students' safety, teachers can encourage students to do their own experiments, provide students with necessary instruments and articles such as test tubes, sinks, evaporating dishes, catheters, alcohol blowtorch, etc., and let students draw their own experimental design drawings, find problems through independent experiments, and learn theoretical knowledge of textbooks in combination with experimental results, which improves students' hands-on ability and independent thinking ability.

In short, in order to adapt to the new curriculum reform, the traditional teaching mode has not adapted to the development requirements of contemporary society. Chemistry in senior high school is a basic subject, which not only reserves knowledge for students' future study, but also lays a foundation for their future life. Constructing an efficient chemistry classroom in senior high school can promote students' participation in chemistry learning, realize their all-round development, improve their comprehensive quality, cultivate their ability to analyze and solve problems, cultivate their good personality and promote their all-round and harmonious development.
