The effectiveness of teaching is to pursue greater teaching efficiency and benefit on the basis of realizing the basic teaching objectives. This pursuit is to cultivate students' learning interest, learning consciousness and self-education ability while completing the teaching task, lay a solid foundation for students' sustainable development, and realize the all-round improvement of students' moral quality, aesthetic taste, innovative spirit and practical ability. Therefore, in primary school mathematics classroom teaching, teachers should scientifically grasp the basic concepts of new curriculum standards and strive to improve the effectiveness of classroom teaching. For how to improve the effectiveness of teaching, the author finds the following strategies for your reference.
First, pay attention to the comprehensiveness of the goal and improve the effectiveness of achieving the teaching goal.
Traditional teaching aims at guiding students to master knowledge, treating students as "containers" to receive knowledge and instilling knowledge into students. Modern teaching regards students as the active subject, and tends to be comprehensive in the positioning of teaching objectives: it not only attaches importance to the teaching of necessary basic knowledge and skills, but also attaches importance to the cultivation of students' self-development ability; Not only develop students' strong physique, but also cultivate their noble and perfect personality; Not only improve students' comprehensive quality, but also strive to develop students' personality. The new curriculum standard of mathematics requires the organic combination of knowledge and skills, process and method, emotion and attitude. It not only emphasizes the understanding and mastery of knowledge and skills, but also allows students to experience the formation and application of knowledge and skills in the process of solving daily life problems; It not only cultivates students' rational reasoning ability and preliminary deductive thinking ability, but also pays attention to let students find and solve problems from real life, so that students can learn to cooperate and communicate in the process of mastering knowledge and solving practical problems, and develop their practical and innovative abilities; While paying attention to knowledge and skills, processes and methods, we should also pay attention to students' emotions and attitudes in learning mathematics, so that students can have a successful experience in mathematics learning activities, meet the needs of each student's mathematics learning to the greatest extent, and let each student develop.
Second, stimulate the enthusiasm of learning and improve the effectiveness of students' active participation
The formation of learning enthusiasm is intrinsically related to the stimulation of learning motivation. The stimulation of learning motivation is the internal factor to form learning enthusiasm. It is a process of changing the formed learning needs from a potential state to an active state by using certain incentive means in a certain teaching situation. As the main body of learning, if students fundamentally lack cognitive domestic demand, learning will not happen; But without the stimulation of external environment, it is difficult to start learning domestic demand spontaneously. Especially for pupils with immature psychology, autonomous learning consciousness and self-control learning ability to be developed, their learning motivation needs to be stimulated and mobilized by teachers, and mathematics teachers should make themselves:
1. Promoter of students' learning. Although it does not control the outcome of students' discussion, it actively participates in guiding, encouraging and monitoring students' discussion and practice.
2. Instructor of students' learning. Through demonstration (speaking and demonstrating), mediation (helping students to link new information with existing knowledge) and guidance (providing clues and feedback for students), students can be helped to learn effectively.
3. Students' study partners. Teachers should regard themselves as learners and complete learning tasks with students.
Third, pay attention to the knowledge structure and improve the effectiveness of students' self-construction.
In the process of knowledge transfer, the generalization of students' original knowledge structure plays an important role. Only by summarizing the knowledge structure can we accurately distinguish the essential differences or similarities between old and new knowledge. Only the generalized knowledge structure can have a stable and clear concept. According to the psychology of mathematics education, the law of students' mathematics learning is "accepting and constructing one by one", which is a process of accepting existing mathematics knowledge under the guidance of teachers' inspiration; At the same time, in this process, students must have their own positive construction activities. Because students are in the stage of physical and mental development, they have not yet developed good study habits and mastered certain learning methods. At this time, the teacher's inspiration and guidance is particularly important. Therefore, under the guidance of the new educational concept, finding a balance between teachers' guidance on students' mathematics learning and students' independent inquiry, and grasping teachers' "involvement" in students' mathematics learning are the key issues in mathematics education. The author believes that the teacher's guidance process should include four steps:
1. Demonstrate the method and process of organizing knowledge through specific teaching process in class.
2. Guide students to organize their knowledge through group or partner cooperation.
3. Let students organize knowledge independently.
4. Communicate and discuss the results.
Fourth, create teaching harmony and improve the effectiveness of friendly interaction between teachers and students.
Good emotional relationship between teachers and students is very important for maintaining students' interest and attention in learning. The emotional communication and coordination between teachers and students and the establishment of mutual trust and cooperation require teachers to use their positive emotions to infect and stimulate students' learning emotions. In order to create a harmonious teaching, teachers should do the following in classroom teaching:
1. Give positive affirmation to any correct answers of students, such as smiling, nodding, repeating and expounding the correct answers of students; Teachers should not ignore or laugh at students' wrong answers or reactions, but should encourage students to continue their efforts.
2. Teachers should try their best to have positive personal communication with each student in class, and listen carefully and accept each student's correct ideas about teaching.
Fifth, pay attention to the appropriateness of teaching and improve the effectiveness of students' all-round development.
Although they are taught by the same teacher in the same classroom and have the same cognitive basis, the differences of students' individual intelligence level, understanding ability and learning characteristics determine that their mastery of new knowledge is uneven. The pursuit of teaching effect should be the all-round development of all students, not the Excellence of only a few top students.
Therefore, every math teacher should fully realize that students are individuals with great development potential and individual differences, and they all have the right to develop and win respect. Teachers must respect every student in personality and communication, care for every student in study and life, and teach students in accordance with their aptitude, so that every student with normal intelligence can develop healthily and succeed.
