First, the rational use of online educational resources to stimulate students' interest in learning
Psychology tells us that interest is the best teacher. When students are interested in a subject, they will naturally learn it well. Mathematics class always gives students a dull feeling, while online educational resources integrate images, characters, sounds and colors, attracting students' attention and curiosity with its novelty, interest and artistry, which can mobilize students' multiple senses to participate in learning. Through multimedia audio, video and other pictures, we create vivid and interesting learning scenes for students, so that they can have emotions when they enter the state, learn knowledge in a relaxed and happy atmosphere and beautiful feelings, which greatly mobilizes their learning enthusiasm and interest. It can be seen that online educational resources are good teachers and friends to stimulate students' interest in learning, and also good helpers for teachers' teaching.
For example, in Determining Location, I rationally applied online educational resources, determined the earthquake location through the longitude and latitude lines of Wenchuan earthquake, and the rescue officers and soldiers arrived at the rescue site at the first time, cleverly introducing new lessons. Then, by teaching PPT courseware to show the seat map of grade two students, students can learn happily in the game, and finally end up at the landing position of Shenzhou VII. The students in the whole class have a strong interest in learning, which greatly stimulates their interest in learning. For another example, when teaching "Understanding RMB", I rationally applied online educational resources and created a supermarket shopping situation. The variety of goods in the supermarket brought the children into the daily shopping situation at once. The children were very interested in learning, and then they went on stage to simulate shopping, and naturally learned the knowledge of RMB exchange in the simulated shopping situation.
Second, make rational use of online educational resources to make mathematics come alive.
"There is mathematics everywhere in life, and mathematics serves life" has become people's knowledge. Proper selection of living materials close to reality in teaching can not only make students realize that what they have learned is closely related to the problems they are exposed to, but also greatly stimulate their interest in learning and make them realize that there are rich mathematical problems hidden in life. The rational use of remote resources is to build a bridge between classroom and life, which is beneficial to students' study.
For example, when I was teaching the meaning of percentage, I used a set of information from online educational resources to lead out the topic and stimulate students' enthusiasm for learning. Through the exchange of information, students feel that learning mathematics is learning things around them, which further stimulates their interest in learning. Then let the students explore independently and sum up their life knowledge into mathematical problems. This teaching process has become a process of students' understanding and learning, which is more conducive to the internalization of knowledge than simply reading books and listening to lectures. For example, Zhou, a math teacher in our school, made reasonable use of online educational resources when she was solving problems in positive and negative proportions, and downloaded a segment closely related to life from online educational resources. Aunt Zhang used 8 tons of water last month, the water fee was 12.8 yuan, and she used 10 tons of water. How much is the water fee? Coupled with what Aunt Zhang and the teacher said, the sounds and images are very realistic, which greatly attracts students' attention and curiosity, makes students feel the close connection between mathematics and daily life, trains students to know things around them with mathematical eyes, and makes students realize that mathematics comes from life, and there is mathematics everywhere in life.
Third, make rational use of online education resources to reduce the difficulty of teaching.
The extensive use of online educational resources has brought educational technology into a brand-new era. It provides services that cannot be replaced by other teaching facilities. While reforming mathematics teaching, it has also changed our teaching consciousness and thinking. It plays a very important role in deepening classroom teaching reform, improving teaching quality and comprehensively improving students' quality. Online educational resources bring students into a vivid and colorful teaching situation by displaying words, images and sounds, so that students can be stimulated by various senses, participate in learning, turn abstraction into images, deepen their understanding of things, and greatly reduce their learning difficulty. Every math class can effectively process electronic teaching materials and produce beautiful images and vivid courseware.
For example, when I teach Fan Diagram, I make full use of online educational resources, download online resources for processing, and then match them with music, sounds and pictures, so that students can understand the characteristics and functions of Fan Diagram at once. For another example, when teaching the derivation of "area and volume formula", in addition to the actual operation, the schematic diagram provided by online educational resources is fully applied. Through the dynamic combination process of practical operation and view, students can quickly establish the derivation process in their minds, which makes the learning content easier to understand and master. For another example, when teaching "Understanding the Circle", teachers and students give examples to understand the circle in life, which not only stimulates students' interest in learning, but also cultivates students' observation and understanding of the physical characteristics and consciousness of the surrounding things, and students reach the cognitive process from perception to representation. Secondly, follow students' cognitive rules, pay attention to guiding students' operation, discover and acquire knowledge about the circle through students' activities such as folding, drawing, comparing and measuring, and understand the characteristics of the circle, so that students can really participate in the whole process of acquiring knowledge. Finally, give full play to the advantages of multimedia, rationally use online educational resources, intuitively and dynamically show the formation process of knowledge, attract students in the form of animation, stimulate students' senses, enlighten students' thinking, help students understand knowledge deeply and cultivate students' thinking ability, which greatly reduces the difficulty of teaching.
Fourth, make rational use of online education resources to broaden teachers' horizons.
In today's information age, the school requires every teacher to organically combine with online education resources. The guidance office often organizes teachers to learn downloaded materials from distance education, such as lectures, lectures, evaluations by famous experts, etc., to broaden teachers' knowledge and then apply them to teaching. Secondly, according to their own schedule, each teacher can watch directly online, at home after school, or online at school. Such activities break the limitation of time and space, save many teachers' concentrated study time, and greatly make up for the lack of funds and time for studying abroad in schools, making most teachers unable to access the most advanced teaching concepts and methods. Due to continuous learning and regular teaching inspection activities in each period, teachers are used to finding some courseware or materials suitable for them on the Internet for processing and integration, and then applying them to teaching.
In a word, online educational resources have opened up a brand-new road for our education and teaching. We believe that as long as we make good use of online education resources, the efficiency of classroom teaching will be greatly improved, and our education and teaching level will certainly step onto a new level.
