First of all, the use of modern educational technology is conducive to stimulating students' interest in learning.
Psychology believes that interest is a cognitive tendency to actively explore something, a source of motivation for students to learn, and a catalyst for intellectual and psychological development. Once students have a strong interest in learning, they will stimulate their inner desire and motivation to learn, and they will concentrate and feel happy. Learning without interest is tantamount to hard labor; Where there is no interest, there is no wisdom and inspiration. Mathematics itself is abstract and boring, and students' interest in this subject is often weak. In addition, students' age characteristics (poor self-control ability and easy to be distracted) make it difficult for a single traditional mathematics teaching method to improve students' mathematical innovation ability. The application of modern multimedia education technology has largely solved the difficulties in traditional teaching. With vivid pictures, concise explanations, pleasant music and timely and effective feedback, we can keep students' strong interest in learning, arouse their enthusiasm, attract long-term attention, participate in classroom teaching with a relaxed and happy mood, and realize the active transformation from "I want to learn" to "I want to learn" and "I am willing to learn".
For example, in the teaching process of triangle, quadrilateral and circle, some dynamic puzzles are used to piece together, which shows that simple graphics can form complex and vivid graphics; Use some architectural pictures and aerospace design drawings to show the universality of simple graphic applications. Learn "A Preliminary Understanding of Fractions" and show the story at the beginning of the class: On the 15th of Mid-Autumn Festival, the Monkey King and Zhu Bajie share moon cakes, but neither of them can make them. Why? Students like two characters very much, and think they are also sharing moon cakes, which is very interesting and attracts students' attention at once.
Second, the use of modern educational technology is conducive to cultivating students' observation ability.
Observation is a perceptual process of knowing an object in a planned, organized and lasting way from a certain purpose and task. Observation is very important in the learning process of geometry knowledge, and students can't do without observation from looking at pictures to knowing graphics. If modern educational technology is used in teaching, it can make the moving things still, and it can also make the static things move on the screen, thus enhancing the purpose and planning of students' observation, and it is also very beneficial for teachers to regulate and control the teaching process.
For example, when explaining the characteristics of a cuboid, I used a cuboid teaching aid to explain the concepts of its face, edge and vertex. However, due to the angle of observation of students and the fact that I was blocked by my hand during the demonstration, students often could not see clearly some characteristics of a cuboid. Now, through the application of modern educational technology, the parts that are difficult to display in the original objects can be fully displayed, which reduces the difficulty of students' observation. Moreover, because computer pictures can combine static and dynamic, stimulate students' senses, make the focus of observation more prominent, and are more conducive to cultivating students' correct observation methods, stimulating students' thinking, improving students' concentration in learning and melting the difficulties of knowledge, students can easily master this knowledge.
Third, the use of modern educational technology is conducive to improving the efficiency of classroom teaching.
The biggest feature of modern educational technology-assisted teaching is that it helps to highlight the teaching focus and disperse the difficulties. You can do many demonstrations with a click of the mouse. No matter how well a teacher expresses, gestures and performs, it is difficult to express some abstract knowledge, which is often the focus and difficulty of a class. Operations such as process reproduction in multimedia teaching can easily solve problems, achieve the purpose of highlighting key points and breaking through difficulties, and achieve twice the result with half the effort. For example, in the lesson of "Understanding Angle", first draw a flashing bright spot on the display screen, and then draw two rays from this point. By demonstrating, it is implied that the definition and size of the angle have nothing to do with the length of the drawn edge. Another example is that "curve, center, radius and diameter" are derived from the trajectory formed by swing, and then the process of drawing a circle is shown by animation, so that students can easily grasp the names of various parts of the circle and understand their relationships.
Fourthly, using modern information technology can realize effective and timely feedback and correction in mathematics classroom teaching.
The interactive performance of the computer can also provide a variety of rich, vivid, large-capacity and fast-response feedback information. In traditional mathematics teaching, the effect of mathematics teaching is often known by correcting students' homework or exams, and students' feedback information is relatively lagging behind. The computer can realize immediate feedback to students' classroom exercises. On the one hand, it satisfies students' eagerness to know their own learning effect and improves their learning enthusiasm. On the other hand, teachers can grasp students' feedback information in time and make the next teaching decision more actively and accurately. Modern information technology can "feedback in class and remedy in time" to prevent mistakes from being introduced into the next class and solve problems that traditional mathematics teaching can't solve. Using the testing function of the computer, all the knowledge in this class can be tested in the classroom. And can call out the questions in order and choose the answers. It is helpful to correct mistakes in time, remedy them and prevent them from "staying overnight" in your mind. Teachers can keep abreast of students' learning situation, which is conducive to timely arrangement and formulation of remedial measures for poor students. In this way, the use of modern information technology to achieve formative testing in the classroom can obtain the information of students' knowledge mastery in time, consolidate and correct it in the classroom, and more effectively eliminate the knowledge errors accumulated by students in their studies.
Five, the use of modern educational technology is conducive to cultivating students' innovative ability.
Modern educational technology is a modern teaching concept with learners as the core and practice as the center, emphasizing "autonomy, cooperation and inquiry" learning. Teachers are more as managers and guides, returning creative thinking to challenging and personalized exchanges and explorations between teachers and students. Modern educational technology makes abstract problems visible, makes static images move, more specifically reflects the process of mathematical thinking, broadens students' horizons, stimulates students' inspiration, develops students' innovative thinking and cultivates students' ability to solve problems in dynamic and vivid teaching activities. For example, the multimedia courseware shows: 185 folk story book, 2 10 fairy story book, 335 children's novel, how many children's novels are more than folk story books? Through subtraction, the formula is: 335- 185. When solving this problem, when students find that "3-8 in the tenth place is not enough", guide them to explore solutions independently and cooperatively. Mathematics is creative thinking. On the basis of considering students, teaching contents and teaching methods, teachers can let students discover problems independently and promote the development of students' creative thinking through multimedia courseware demonstration.
In short, the proper use of modern educational technology in primary school mathematics classroom teaching can show the inherent laws of knowledge from different angles and ways, break through the limitations of time, space and abstraction, let students fully feel and understand the generation and development of knowledge, broaden their horizons, and help students cultivate their innovative consciousness and ability and develop their comprehensive quality.
