First, optimize the teaching process of mathematics, overcome the key points and difficulties of teaching
In the teaching of mathematics in primary schools, breakthrough key and difficult knowledge is an important part of teaching. How to break through the difficulties is a key issue that every math teacher cares about. The application of modern teaching technology can make abstract and difficult mathematics more vivid in the form of animation, sound, etc., so that students can more directly perceive and understand the teaching content, help students understand the inherent laws between mathematics knowledge, and more Well construct the knowledge structure of mathematical knowledge.
2. Demonstrate the process of knowledge generation and enhance students' participation in mathematics learning
The study of mathematical knowledge must show the process of formation in order to leave a deep impression on students. In the process of teaching mathematics in primary schools, teachers use information technology to demonstrate the process of knowledge formation, which enables students to grasp the general rules of knowledge formation during the learning process, and present some abstract concepts and formulas to students in an image. The purpose of the effect. For example, when studying the course "Knowledge of Rectangles", the teacher can use the multimedia courseware to flash the faces, vertices and edges of the cuboid, so that the students can clarify the names of the various parts of the cuboid. The powerful function of information technology can dynamically demonstrate the knowledge of mathematics, making the original abstract knowledge more concrete. This clear image display process is very difficult for traditional mathematics classroom teaching, but the multimedia courseware can be easily achieve.
Third, change the practice mode to improve the effectiveness of mathematics curriculum teaching
Practice is an important way to consolidate mathematics knowledge, and it is very important to learn mathematics knowledge in primary schools. A series of practice topics written by information technology can be passive and active. Teachers can prepare various types of questions in advance through computers, and practice key and difficult knowledge in all aspects and angles. At the same time, the advantages of information technology are also reflected in the ability to set up some interesting dynamic topics to cater to the cognitive characteristics of primary school students. For example, the form of "small baboon looking for mother" and "chicken and rabbit cage" not only allows students to consolidate what they have learned, but also helps students to enjoy the joy of success. In the course of the after-school practice, the multimedia courseware can save the time of the blackboard, and can provide students with a large number of valuable exercises in a short period of time to promote the improvement of teaching effects. For example, in the process of consolidating and practicing knowledge, if the student chooses the correct answer, a smiley face can be displayed on the screen, and then accompanied by the voice "You are awesome", enhance the sense of achievement of the student's learning. If the student answers the mistake, it doesn't matter. The screen can show some encouraging words such as “Re-energize†for the students, which can create a relaxed and pleasant learning atmosphere for students, and the fun of mathematics learning is also enhanced.
