Ge Xiao: Zhang Xiaomei.

First, there are some factors.

(1) Students' preparation before class: The teaching concept of the new curriculum requires us to optimize the classroom structure, increase the classroom capacity, and put the main time on the inquiry of problems. Whether this can be done depends on the students' preparation before class. If the preparation before class is insufficient, it will inevitably affect the progress of the class, and teachers have to spend their time on non-critical issues. As far as students are concerned, they may not keep up with the classroom rhythm, and over time, it will cause learning difficulties.

(2) Teachers' emotional state in the classroom: In the final analysis, classroom teaching is a kind of communication, and emotional communication is both the starting point and the end point. It is self-evident that teachers' emotional state affects the effectiveness of classroom teaching. At this point, teachers who think they are experienced in teaching often lack passion and are not as good as young teachers.

(3) Proficiency of teaching materials: In order to effectively organize student activities, teachers must master teaching materials skillfully, which can be scattered or collected. If teachers are not familiar with the teaching materials, it will inevitably affect the development of classroom activities, thus affecting the teaching effect. Young teachers pay special attention to this point and must strengthen the study and research of teaching materials. )

(4) The effectiveness of classroom organization: Before class, we should carefully design the classroom process, preset the big links of the classroom, ensure the interlocking, and make the classroom activities under our control. The new curriculum advocates inquiry learning, situational learning and cooperative learning, which does not mean that classroom activities can be endless.

(5) Characteristics of the problem: The effect of classroom activities depends on the object and carrier of the activity-the quality of the problem. A good question should not only guide the classroom teaching objectives, but also be decomposed into sub-questions one by one, and go deep at different levels to lead students to achieve the curriculum objectives.

(6) Presentation of new knowledge: A lesson often has several knowledge points, which are important and difficult. How to turn these "points" into problems one by one and present them to students in a way that conforms to the logical order of disciplines and students' cognitive laws is the key to preparing lessons. If it is not handled well, it will reduce students' interest in learning and cause students' learning difficulties.

Second, the reasons and countermeasures

As we all know, 40 minutes of class can be divided into effective time and ineffective time. The so-called effective time refers to the part of time that is really used for students to learn and accept knowledge and information and develop their abilities in actual teaching. So we often say that this course is not good, in fact, it means that this course has relatively more invalid time. This is the inefficiency of classroom teaching. The main reasons for the inefficiency of classroom teaching are as follows:

First, the teacher's reasons

1. Teachers lack proper quality, can't correctly understand the far-reaching significance of education, and engage in educational work carelessly or even take it for granted. This is of course very rare.

2. Inadequate preparation before class makes the classroom goal invalid or the teaching content invalid. I can't explain clearly or don't want to explain clearly the teaching objectives and significance of a class, so I have to pay attention to the teaching materials and teachers for the time being and rush to class. It also includes the self-righteous old teacher consciousness.

3, the pertinence is not strong, the method is invalid or even the classroom language is invalid. That is, the goal is too arbitrary, the teaching is divorced from the goal, and the necessary learning method guidance is lacking. Even the teacher's language is full of nonsense and not refined. The content has nothing to do with the teaching objectives. In teaching, students cannot be guided in a targeted way.

Second, the reasons for students

1. Some students do not participate widely or have low enthusiasm because the teaching content or teachers are not interested in learning. The teaching process is boring, which can't arouse students' interest in learning or the teacher's language is wordy and disorderly, which leads to students' disgust. It directly affects the efficiency of classroom teaching.

2. A few students lack correct learning consciousness, unclear learning objectives and poor learning foundation. They behave casually in class, don't like to use their brains, and even make small moves, which affects the curiosity of the whole class or the students around them.

3. Very few students do not participate in classroom activities for a long time because of poor academic performance and poor self-control ability, and even make troubles that affect the whole class.

Third, external factors.

In actual teaching, it is inevitable that parents will enter the classroom to find their children, power failure and other problems that cannot be prevented and overcome. Or teachers who are in a bad mood in class will also affect the efficiency of classroom teaching.

To sum up, in fact, the real efficiency of a class depends on the ratio of students' real learning behavior to 45-minute class hours. The higher the proportion, the more obvious the learning effect of students. Therefore, we should try our best to prolong the effective learning time in class and improve the efficiency of classroom teaching.

First of all, master modern educational concepts and advanced educational theories to improve their teaching quality.

Education should keep pace with the times, and teachers must attach importance to learning and constantly update their own concept system and knowledge system. Only by mastering modern educational concepts and advanced educational theories can we better implement the new curriculum standards and improve the teaching level in the teaching reform.

I won't discuss this point, but it is very important, which directly affects our teaching objectives and teaching behavior, teaching effect and students' growth.

Second, build a harmonious relationship between teachers and students and create a harmonious classroom teaching environment.

In actual teaching, some of our teachers' working methods are simple and rude, and they can't patiently educate problem students. They often use criticism, accusation and even corporal punishment to stimulate students, so as to achieve the purpose of "stimulation". And the result is often counterproductive. The most terrible thing is that it has formed a deadlock with students, which has caused students' rebellious emotions. It is conceivable that such a teacher-student relationship will inevitably directly affect the classroom teaching efficiency. Therefore, it is very important to become a respected teacher, improve classroom teaching efficiency and establish a good relationship between teachers and students. This requires our teachers to have a correct view of students, treat every student with love, pay attention to respecting and trusting students, pay more sincere praise and praise, face students' problems with more encouraging methods, and learn to be tolerant. We are familiar with the story of "touching each student's head" and the story of "quietly handing pens to students who steal things", which has good enlightenment to our education.

Practice has proved that only by abandoning the so-called "dignity of being a teacher" and "getting along with students" can we get to know your students, what they want, what they don't like, how they like to attend classes and how to learn, and it will also be beneficial to your teaching design and classroom teaching and build a harmonious relationship between teachers and students. Students naturally want to attend your class, like to listen to your class, are willing to do your homework, and behave positively, so classroom teaching efficiency is naturally inefficient.

Third, skillfully set up "stimulation island" in classroom teaching to improve classroom learning efficiency.

We know that students' active thinking activities are an important prerequisite to ensure efficient classroom teaching. If the students in the classroom are like a pool of clear water, then the excitement center of superior thinking designed and established by teachers is like an "island". The ingenious "exciting island" can effectively stimulate students' thinking activities and prolong the effective time of classroom learning.

"Exciting Island" is divided into three types: starting island, strengthening island and continuing island. Distributed before class, during class and at the end of class. We often say that "creating a good teaching situation and introducing new lessons skillfully" is the starting island. Carefully designing teaching links, asking questions skillfully and speaking concisely, or attracting students' attention with appropriate teaching methods (such as multimedia and colored blackboard writing) to make them feel novel constantly, is the strengthening island, and the "one classic joke or story in each class" we advocate can effectively wake up students when they feel tired or distracted. This can be said to be a continuous island. Teachers carefully designed the "stimulus island" to make the three islands skillfully connected, which can arouse a pool of clear water and produce a good "field effect".

This requires our teachers to work hard before class, not only to thoroughly study the teaching materials, but also to master more theories and methods in order to design a suitable "stimulus island". Effectively improve the efficiency of classroom teaching.

In a word, classroom efficiency is the key to improve teaching quality and better cultivate students, and it is also the key to prevent mistakes and improve Excellence. Everyone who wants to be a "teacher", "master" or even "master" should make more fuss about this.
