With the development of society, the wide application of information technology. Information technology enters the elementary school science teaching classroom is a new method and form of science class teaching. Science classroom education in the network environment enriches teaching resources and expands the teaching model. It transforms the traditional, static, and closed classroom into a modern, dynamic, and open classroom teaching model, making the science classroom more vivid, more contagious, and more stimulating students' interest in learning and curiosity. Allow students to easily learn more in a limited amount of teaching time.
First, the use of information technology, making it difficult
There are a lot of materials for students to explore in science class. Students are required to conduct investigations, investigations or experiments under the guidance or guidance of teachers. However, some activities cannot be fully demonstrated in the classroom, such as "The Growth of Plants". In one unit, the experiment uses red beans to observe the roots, and the stalks are observed by planting the balsam, but the roots of the plants absorb water, and the students of the stems how to transport water are incomprehensible. At this time, we can use the network technology and multimedia courseware to let the students "see" the water of the plant roots and the water flowing from the stems and veins of the plant to slowly flow, so that the roots of the plants absorb water and the stems transport moisture. A difficult point is solved. For example, a series of astronomical texts such as "The Revolution and Rotation of the Earth", as well as texts on the movements of human organs such as "The Digestive Organs of the Human Body", "The Organs of Blood Circulation", "What Will It Work Like", can use the network and multimedia. The courseware is vividly and vividly displayed to the students, so that the students' scientific inquiry activities are not limited to the classroom, and the expansion of learning time and space is realized.
In addition, there are many new knowledge and new ideas in the teaching of science courses. They are restricted by security and other aspects. It is impossible to conduct actual demonstrations in the classroom. In order to enhance students' perceptual knowledge, they can use various modern educational techniques. During the teaching process, these experiments and phenomena are simulated to achieve the simulation effect, or the phenomenon of amplification, delay, etc., so that students can enjoy learning and acquire knowledge in the demonstration and experimental environment without obstacles.
Second, improve learning interest and enhance perception
The traditional teaching methods mainly rely on chalk, blackboard, wall charts or models. Students have little interest, while the science classrooms in the network environment are vivid, vivid and intuitive, and students have a strong interest. For example, if you teach the "Silkworm" lesson, you can use multimedia video, and students can easily understand it. Students both aroused interest and strengthened knowledge.
With the development of education, the supporting teaching materials include more and more video materials. On the one hand, these video materials help teachers solve the teaching difficulties, on the other hand, they also expand the students' horizons. In addition, I also encourage students to watch educational programs on TV stations outside the classroom, such as "Animal World", "Technology Education", "Scientific Quest" and other columns. When students watch such programs, they will mobilize all their knowledge, experience, and ability to process information and judgment.
Third, enrich educational resources and deepen inquiry
The Science Curriculum Standard states in the course "Basic Philosophy" that "the science curriculum is for all students."
1. “Scientific learning should be based on inquiry.... Science courses should provide students with sufficient opportunities for scientific inquiry, so that they can experience the joy of learning science, increase the ability of scientific inquiry, and acquire in the process of scientific inquiry like scientists. Scientific knowledge forms a scientific attitude that respects facts and is good at questioning, and understands the history of scientific development."
2, traditional teaching due to time and space constraints, teachers almost become the only source of information in addition to textbooks. At this time, the use of network technology in teaching can make up for the shortcomings of traditional teaching. Some information will become a new source of knowledge and become an infinite source of learning wealth. For example, in the course “Protecting Ecological Balanceâ€, teachers can divide students into several groups one week in advance, so that students can log in to relevant environmental websites during the information class to collect information online, and then students will sort, filter, and summarize the information. Sexual knowledge. This makes full use of information technology to allow students to collect a lot of useful information, and more importantly, to improve students' hands-on ability and self-learning ability. Under the guidance of the teachers, students can choose their own content to learn and explore independently according to their own interests and abilities. Students no longer simply passively accept knowledge, but become the main body of information processing and processing, and become the active builder of knowledge. This is difficult to achieve in traditional classrooms. It truly reflects the "Science Curriculum Standards" pointed out in the "Basic Concepts" of the course: "The science curriculum should be oriented to the new concept of all students!
Fourth, improve the ability of independent inquiry and learning
To a large extent, the traditional teaching mode is difficult to master the science classroom teaching based on inquiry learning. The network technology and network environment break the traditional time and space restrictions, showing a greater degree of freedom and openness, and students will be Bring into the vast world. Such as "the movement inside the earth", "the universe" and other unit content abstraction, this part of the knowledge we can use the network technology, courseware and other images vividly reproduced for the students to watch, so that the virtual and the real complement each other, the student's intuitive knowledge of this kind of abstract knowledge Understand understanding.
Pupils' science classrooms should provide primary school students with sufficient opportunities to explore science, so that primary school students can experience the fun and happiness of learning science in the process of scientific inquiry like scientists, increase the scientific inquiry ability of primary school students, and acquire scientific knowledge. The ability to form a respect for the facts and the ability to question the attitude of science, to further understand the history of scientific development, and slowly understand the nature of science. In teaching, we must make full use of information resources and modern means. Integrate information technology into the teaching of elementary science, use various information resources and modern means to introduce the living water of the times, and combine with the content of science teaching in primary schools to make students' learning content more colorful, more contemporary and closer to life. And modern science and technology; changing traditional scientific teaching content not only makes scientific textbooks "live"; in such an era of information explosion, in such a rapidly changing information world, we must use information technology and science classroom network environment. Under the guidance of the new concept, we must pay attention to the research of science teaching in primary schools under the network environment, grasp the entry point of the combination of network and education, and constantly explore new types of network teaching and scientific integration. Teaching mode.
