In the classroom, after a period of teaching, teachers make students get concrete and obvious progress and development, which is the goal that every teacher is committed to pursuing. However, in actual teaching, students' progress is always unsatisfactory, and they can't get twice the result with half the effort and get immediate results. The author thinks that the reason is that students are inefficient in class. Now I will talk about some of my own ways to improve the efficiency of students' lectures.
Cultivate students' good habits in class.
1, make it clear before you speak.
In class, students are often led by the nose because they are not clear about the teacher's questions or passively accept the topic of classmates' speeches. When they finish this kind of problems independently, they don't know where to start, or have a little knowledge, and the error rate is very high. In the long run, students will form the bad habit of following blindly and listening to other people's suggestions. In order to achieve the best results in a limited time, it is necessary to cultivate students' habit of making questions clear before speaking. That is, what is the first problem that students should solve? Find the key words in the question? What are the requirements? Then let the students think around this problem, listen to other people's speeches, judge whether other people's speeches are related to the current problem and whether they are correct, discuss with their classmates around key words, and then express their own views and form strategies to solve the problem. In this way, students can think in a range, concentrate, overcome the subjectivity and randomness of students' thinking, be targeted, simplify complex problems, and effectively improve the efficiency of listening to lectures. For example, the teaching grading application topic "The original price of a sweater is 56 yuan, and the current price is lower than the original price. What is the current price? " Teacher's question: What does this question ask you? What do you think are the key words in the question? And ask students to write the teacher's questions on paper first, and then discuss them in groups. Soon most students found the keyword "decrease" in the known conditions. After the teacher's proper guidance, students can refer to key words to explain to their deskmates, draw line segments by hand and write formulas. Teachers are also involved, asking students to speak in an orderly manner. After listening to others' speeches carefully, you should not interrupt others' speeches at will. They should respect their classmates and help each other make progress. Ask the students to clarify their questions before speaking. Teachers must set an example. First, be concise, grasp the key to solving problems, ask questions around key points, guide and explain students' difficulties, and stick to this practice for a long time. Students' listening will be improved obviously.
2. Draw pictures and place items.
Psychological research shows that students have the best learning efficiency when they concentrate. In class, there are often some students who have little knowledge because of their inattention, which leads to gambling, knowledge gap, weariness of learning and worse academic performance. There are many ways for students to overcome this bad habit. I tried this in class: in teaching, "from Class 6 (1) to Class 6 (2), the number of students in the two classes is equal. It turns out that the ratio of Class Six (1) to Class Six (2) is (): (). " Ask students to draw a picture (simple line drawing) or analyze the meaning of the question in kind.
In this process, students are fully mobilized, naturally concentrate, observe, think and communicate with classmates, and everything becomes positive and harmonious. Students have experienced the formation and development of knowledge, mastered methods in the process of trying and exploring, and gained successful experience in the process of solving problems. The hardest part is actually in the beginning At the beginning, some students have some difficulties in drawing line segments, but if they stick to it, they will develop a good habit of drawing line segments and analyzing the meaning of questions, laying a solid foundation for further learning mathematics.
3. Question and speak the truth boldly.
"Learning without thinking is useless, and thinking without learning is dangerous." Only by combining learning with thinking can students form correct concepts, innovate and develop. Reflecting on our classroom, some students often want to speak but dare not. Some wait to see what others say first, some are uncertain and embarrassed to ask, some pretend not to understand, some ask him to say, and he repeats what others say and responds in a hurry ... These bad habits restrict the development of students' thinking and personality and affect the efficiency of students' lectures. Therefore, in the classroom, only by encouraging students to question boldly and tell the truth boldly can students truly become the masters of the classroom and have interest in learning and thirst for knowledge. For example, teach (1) that a 3-meter-long rope has run out of meters, how many meters is left? (2) A 3-meter-long rope was used. How many meters are left? After finishing this question, I asked, "Who still doesn't understand? Students will help you! Speak boldly, indicating that you are making progress, even if you are wrong. " When I found a student with learning difficulties hesitating, I smiled and motioned the classmate to stand up with my hand. "Teacher, I still don't understand (2) what can't be calculated by' 3-'?" The classmates cast strange eyes, and I immediately praised this classmate: "He dares to tell the truth and is an example for us to learn. The teacher is very happy. Who do you want to ask to help you? " I asked Ray to help me solve this problem. "The items in (1) are expressed in units. The number of copies in question (2) ... ""Thank you, I understand. "The students' explanations are so real, and the students who listen are so attentive.
