From this point of view, "integration" embodies such a spirit: whether it is information technology or subject courses, we should make great efforts to combine them into a whole at a new level-a brand-new curriculum system, which means a revolution and a challenge for mathematics teaching.
Next, I will take the lesson of "data collection and arrangement" as an example to talk about how to integrate mathematics with information technology and what role information technology has played.
Data collection and collation is the first part of simple statistics. Statistics is an important branch of mathematics. With the progress of society and the continuous development of science and technology, the application scope of statistics is increasingly extensive. In this class, I asked the students to discuss statistics in groups, how many invitations were received, and how many in each color. The students posted and commented to form a bar chart. In the process of collecting and sorting out invitations, the students came up with innovative methods. Red, pink and green invitations, some groups stick invitations horizontally, while others stick invitations vertically. Although the sorting method is inconsistent, the pasted result is correct. Students learn statistics, experience statistics, learn communication and experience cooperation in the process of data collation. Diversified teaching strategies promote students' inquiry learning and cooperative learning, and enhance their collective consciousness.
In this class, I used information technology to create a teaching situation closely related to the teaching content, which stimulated students' interest in learning. First, I asked the students, "Students, do you know what year this year is?" The students know that this year is the Year of the Monkey. Then, I use multimedia to show pictures of little monkeys. The little monkey's tail can move up and down, which embodies the naughty characteristics of the little monkey and attracts the students' attention. At the same time, I wish you a happy birthday, which gives students a refreshing feeling. After that, the life scene made by Flash was presented, and ostriches, squirrels and eagles celebrated the birthday of the little monkey. At this moment, I said, "Today is the birthday of the little monkey, so it also invited some friends to the birthday party. Now it wants you to remember "roll call" and help it count which friends and how many? " At the same time, the courseware displays the roster, and the statistics table appears after clicking:
Animal name
total
ostrich
squirrel
hawk
Count quantity
Students fill in the statistics according to the pictures. The comprehensive application of multimedia in this link has stimulated students' interest in learning and desire to explore. Finally, I introduce the topic of blackboard writing, so that students can clearly understand the learning content of this lesson and deepen their impression.
In the stage of exploring new knowledge, I constantly create situations. "In order to express our gratitude to everyone, the naughty little monkey sent an invitation to the students sitting here. Please pay attention. " Multimedia presentation flip invitation:
please
card
Dear friends:
Welcome to my birthday party.
Your friend monkey
Then ask the students to read and say the contents of the invitation. Then, the teacher asked, "What do you want to say when you see the little monkey's invitation?" Students may say, "Thank you, little monkey, I will definitely attend your birthday party." Or you might say, "Little monkey, I have a program to celebrate your birthday?" This link distracts students' thinking and enlivens the classroom. After that, the students discussed and counted in groups, and how many invitations were received, several in each color. The students posted and commented to form a bar chart. The comprehensive function of multimedia in this link breaks through the key points, disperses the difficulties, has an incentive effect on students, and can mobilize students to actively participate in the whole process of collection and collation. Diversified teaching strategies promote students' inquiry learning and cooperative learning, and enhance their collective consciousness.
Then, I continued to create the situation. "In order to make the birthday party more lively, some students in our class have prepared wonderful programs. This is a survey made by the teacher. " At the same time, the multimedia first presents a statistical table, which is very clear: each box represents 2 people; Show me another statistical table, and make it clear that each square represents four people. Then show the comparison chart. Students observe: I understand that the data represented by each square can be arbitrary. Finally, I summarize the new lesson. The comprehensive application of multimedia in this link solves the difficulties, improves the learning effect of students, is suitable for students and helps to achieve the teaching purpose.
In the second stage of consolidating new knowledge, I made scenes simulating streets and various motor vehicles coming and going with Flash. Show it: Xiaohua counted the number of various motor vehicles passing by a roadside in 10 minutes. Please help her complete the statistics and histogram. The comprehensive application of multimedia in this link is not only closely related to the course content, but also closely related to real life, with strong pertinence, which can effectively attract students' attention, maintain students' interest, and help improve the learning effect and achieve the teaching goal.
Through the above example, my feelings mainly include:
First, the integration of information technology and mathematics is conducive to cultivating students' cooperative spirit.
Dr. Yang Zhenning pointed out: If the Nobel Prize could be completed independently in the past, then since the 1980s, especially since the information society, without people's joint participation and mutual cooperation, any major invention and creation would be impossible. Under the trend of economic integration and specialized division of labor, cooperation consciousness and cooperation ability have become important qualities for people's survival and development.
Second, the integration of information technology and mathematics dares to say "no" to traditional textbooks.
There is a poem circulating during the curriculum reform: give the child some rights and let him choose for himself; Give the child a chance to experience it by himself; Give the child a little difficulty and let him solve it himself; Give the child a question and let him find the answer by himself; Give children a condition to exercise by themselves; Give the child a space and let him go forward by himself. Therefore, teachers should dare to break through the limitations of textbooks, boldly try new ways of teaching reform, embody the new concept of "teaching with textbooks", and creatively reorganize and process textbooks to make the selected content close to real life, which will make students interested in what they have learned, stimulate students' desire to explore and give people a refreshing feeling.
Thirdly, the integration of information technology and mathematics is conducive to students' autonomous learning.
The new curriculum standard of mathematics puts forward that in mathematics teaching, we should actively advocate independent, cooperative and inquiry learning methods. This concept not only emphasizes the change of learning style, but also emphasizes that the main body of learning and development is students, and the main position of students in curriculum and teaching has been reconfirmed.
In the traditional teaching process, everything is dominated by teachers: from teaching content, teaching strategies, teaching methods to teaching steps, students can only passively participate in this process, and the integration of information technology and Chinese subjects has completely broken this situation. In interactive learning environments such as multimedia computers, students can share and share human learning resources equally, and they can choose learning contents, methods, strategies and development goals according to their own learning foundation and interests. In this open learning space, students have the possibility of active participation and a world of autonomous learning.
Fourthly, the integration of information technology and mathematics encourages students to innovate boldly.
Suhomlinski said: "In people's hearts, there is a deep-rooted need to be a discoverer, researcher and explorer. In the spiritual world of children, this demand is particularly strong. " Therefore, teachers should explore the diversity of problems, solve the diversity of problems, encourage students to actively seek different solutions to the same problem, spread their own thinking, and stimulate students' desire to explore and the fun of autonomous learning.
Our education and teaching activities should strive to create cooperative learning situations and build a stage for students to develop cooperative consciousness and ability. Information technology is involved in classroom teaching, and a new learning mode of "independence, cooperation and inquiry" is constructed, which fully shows the multidirectional, rich and fast information exchange. We can provide students with three-dimensional opportunities for multi-directional communication through various modes of friendly cooperation, such as teacher-student interaction, student-student interaction, teacher-machine interaction, teacher-machine interaction, vitality interaction and vitality interaction, which is conducive to cultivating students' cooperative spirit.
"I don't know, I didn't see it. Mathematics is wonderful. " I believe in Intel? 0? 3 The future education will play a role as a booster for the development of education, add new vitality to the implementation of new curriculum standards and promote the prosperity of education. In order to make the math class more colorful, we should let Intel? 0? 3 Future education enters the mathematics classroom.
