First, organically combine multimedia teaching with traditional classroom teaching to better serve classroom teaching.
1, appropriately use multimedia teaching to create situations and stimulate students' interest in learning.
It is precisely because of the advantages of multimedia that individual teachers think that as long as they use multimedia, they will be able to have a good class, which leads to the use of multimedia for the sake of using multimedia, which is counterproductive and has a bad effect. As a teaching method, multimedia should serve teaching purposes. Only by choosing appropriate teaching methods can we realize the optimization of teaching and give full play to the characteristics of multimedia teaching. Whether a multimedia class is used properly or not, the only criterion is whether it is conducive to the completion of teaching tasks. Nowadays, with the extensive use of multimedia, boring math classes have become colorful. Students can not only clearly see different geometric shapes and beautiful axisymmetric figures, but also stimulate students' interest in learning.
2. Rational use of multimedia teaching to improve classroom efficiency.
The application of multimedia teaching requires teachers to make more efforts before class, so that students can easily break through the key points, difficulties, contents and design links in class, thus improving classroom efficiency. For example, after learning the definition of fractional equation in the first section, which can be transformed into a linear equation with one variable, I designed the courseware "Is the following equation a fractional equation?" However, multimedia teaching cannot replace the traditional classroom teaching mode. We should take this as a basis and never ignore textbooks. For example, when talking about "the solution of fractional equation", teachers must write down and solve an example on the blackboard with students to standardize writing. In the process of writing on the blackboard, teachers and students exchange feelings to realize * * * knowledge, and then let students point to the lecture process on the blackboard, analyze the reasons for root growth, and summarize the general steps to solve the fractional equation, which reflects the effectiveness of the classroom. Some teachers took a class, and dozens of pictures were displayed, without writing a word, and students didn't do any questions, so blindly using multimedia teaching not only dazzled students, but also gained nothing.
3. Multimedia teaching cannot replace traditional classroom teaching.
Multimedia teaching attracts students with its intuitive and clear pictures, and introduces them into our classroom teaching like a beautiful scenery. When students are faced with a lot of colorful multimedia information, they just browse the information resources, but don't really construct the knowledge structure. Therefore, when preparing lessons, teachers should choose appropriate teaching methods according to the characteristics of teaching materials and students' cognitive level, so that multimedia teaching can give full play to its advantages and serve the classroom. For example, when talking about translation and rotation, I made a slide before class. In the plane rectangular coordinate system, with the origin as the rotation center, the line segment OA rotates clockwise and counterclockwise, and in the process, students are allowed to establish a movement. Have a sense of direction and angle, and then let the students draw pictures in their books and draw rotating figures on the blackboard. Point out students' mistakes and correct them, so as to better implement the "two basics". Only by organically combining them can we better serve the classroom teaching and promote the development of students.
Second, guide students to make rational use of teaching resources
Curriculum resources need teachers to organize, develop and utilize, and teachers should actively and creatively use all available resources to serve teaching. It should also be a guide for students to use curriculum resources. For example, when I talk about rotation, let the students cite whether there is any graphic movement in our classroom that belongs to rotation. What are some examples of rotation in life? Students find the movement of ceiling fans, the movement of clock hands and the rotation of doors in the classroom. All belong to the rotation of graphics. Through the process of students giving examples, we can deepen our understanding of the concept of rotation, establish the consciousness of applied mathematics, and stimulate students' confidence in learning mathematics well. Teachers should guide students out of the classroom and school, make full use of all kinds of resources inside and outside the school, study and explore in the social environment, and let students realize that mathematics comes from life. Practical problems require us to learn math well.
Third, teachers should establish the belief of lifelong learning.
Lifelong learning is the survival concept of 2 1 century. Teachers must master the basic theories and methods of educational technology, learn information technology knowledge and improve computer operation ability. In the process of making courseware, I also encountered many problems, such as not scoring and not drawing moving geometric figures. I humbly consult computer teachers, learn from their experience and improve my professional ability. With the help of information technology, especially other resources provided by various educational websites and network environment, we will continue to learn new and comprehensive professional knowledge, improve the professional teaching level, and make full use of the vast communication space and communication means provided by the network to communicate with other teachers, educational experts and educational technology researchers.
Secondly, teachers should strengthen the cultivation of teachers' morality and improve their professional level; Teachers should have a heart and care for every student. We should infect students with noble personality charm, influence students with rigorous academic attitude and strict requirements, with a highly responsible attitude towards students, and with self-improvement personality style to improve their professional ethics. Classroom teaching is the most basic and effective way in school education, and it is the main position to implement quality education. Open heuristic teaching, with the help of new multimedia assistance and teacher-student interaction, students' autonomous learning activities will become the direction of future classroom education reform, and optimizing classroom teaching is the main aspect of improving quality education.
Only from the specific characteristics of teaching materials and students' learning situation, rational use of teaching resources and selection of appropriate teaching methods can the optimization of multimedia teaching be realized. Persist in learning, establish the belief of lifelong learning, and strive for excellent teachers in the new century.
