First, optimize the teaching process of mathematics, overcome the key points and difficulties of teaching
In the teaching of mathematics curriculum 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 content of teaching, and help students understand the inherent laws between mathematics knowledge. Better build the knowledge structure of mathematical knowledge. For example, in the process of learning mathematics knowledge in the first grade of primary school, there is a topic that allows students to calculate the total number of cubes stacked together according to certain rules. Many students have no way to calculate the number of invisible cubes. Through the application of modern educational technology, computer technology can be used to remove the squares placed on top of them, and the squares placed below will appear in front of the students. Then the teacher uses modern educational technology to demonstrate several different placement modes, students can master the method of calculating the cube, and the students' imagination can be well cultivated.
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 teaching process of the elementary school mathematics curriculum, the teacher demonstrates the knowledge formation process through information technology, which enables the students to grasp the general law of knowledge formation in the process of learning, and present some abstract concepts and formulas to the students. Improve the purpose of teaching. 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. On this basis, students can master some preliminary knowledge of the cuboid through independent exploration, such as the cuboid has several faces, several vertices and several vertices, etc. Then the teacher uses multimedia technology to verify the results with the students. Students' impressions of this knowledge will be even more profound. Students find that their summaries are verified to be particularly exciting, and the enthusiasm for learning mathematics has improved. The powerful work 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, "Small baboons looking for mothers" and "chickens and rabbits with cages" and other forms can not only help students to consolidate what they have learned, but also help students to enjoy the joy of success. In the process of carrying out after-school exercises, multimedia courseware can save time for blackboard writing, 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 students answer the mistakes, 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.
