The so-called efficient classroom, as its name implies, refers to the classroom where the efficiency or effect of education and teaching can reach a fairly high goal. Specifically, it refers to a classroom that is more efficient and effective in completing teaching tasks and achieving teaching objectives, and achieves higher influence and social benefits in education and teaching. Efficient classroom is the highest realm of efficient classroom, and efficient classroom is based on efficient teaching. ?

First, make full preparations before class to lay a solid foundation for creating an efficient chemistry class?

Guide students to preview?

Preview can not only cultivate students' self-study ability and independent thinking ability, but also broaden their thinking and improve their listening and note-taking level. It can be seen that preview plays a very important role in classroom teaching. Preview is divided into semester preview, weekly preview and daily preview. Semester preview is to require students to read through the textbooks for the next semester in the winter vacation or summer vacation before the start of school. ?

2. Strengthen the accuracy of preparing lessons?

Teachers should prepare lessons three times before class: master class, intensive class and detail class. Master lesson preparation refers to a series of activities, such as organizing teachers to collectively study the syllabus and teaching materials, analyzing the learning situation, formulating unit lesson plans, decomposing lesson preparation tasks, feeding back teaching practice information, etc. In the activities, masters and assistants carefully prepare lessons and make speeches, and other members express their opinions after listening to them to supplement and improve the collective lesson preparation content; Intensive lesson preparation refers to the second lesson preparation (preparing textbooks, preparing students, preparing teaching methods, preparing exercises, etc.). ) on the basis of collective lesson preparation, according to the actual situation of the class you teach. To strengthen lesson preparation, we must pay attention to the comprehensiveness of teaching content, the flexibility of teaching methods and the diversity of exercises, and strive to achieve a clear idea of teaching materials, students, teaching methods and objectives. This process requires teachers to consult 3~4 related materials, which is a heavy workload; Careful lesson preparation means that teachers enrich the details of each link of teaching according to the actual situation of each class and their own unique thinking, and the designed learning plan should be conducive to the teaching of this class. Especially in chemistry class, there are many knowledge points, many contacts and careful investigation, so we should be fully prepared. ?

Second, optimize the progress of classroom teaching and create a learning classroom?

Classroom teaching time is the guarantee of improving teaching quality, which determines the determination of classroom teaching objectives, the selection of content and the arrangement of structure. Reasonable allocation of teaching time will inevitably become the main content of teaching design. Only by grasping the time, using it reasonably and optimizing the classroom progress can we ensure the high efficiency of the classroom. ?

Third, select classroom exercises and homework content to strengthen the digestion and consolidation of knowledge?

Classroom practice is a training activity that teachers organize students in a planned, purposeful and targeted manner according to the teaching content and teaching purpose. It is interspersed in the teaching process and plays an extremely important role in understanding, consolidating and applying knowledge and transforming knowledge into ability. It is the best way to test students' learning situation, so the choice of classroom assignments should be closely combined with textbook exercises, which is basic, typical and novel. Homework after class is a collaborative process, which extends and strengthens classroom knowledge. Homework after class should be divided into compulsory questions and multiple-choice questions, so that every student can improve, and at the same time, it is necessary to strengthen the inspection of homework completion to prevent some students from being lazy. Common problems in homework should be explained by the whole class, and individual problems should be solved separately, so as not to overstock the problems in students' study. ?
