First of all, talk about textbooks.
1. teaching content: this lesson is the second volume of the experiment of people's education press, data collection and collation.
2. teaching material analysis In this unit, students learned the basic knowledge of statistics on the basis of comparison and classification. In order to make students understand the necessity of learning statistics, the textbook chooses life scenes closely related to students' lives. By participating in interesting investigation activities, students can experience the process of collecting and processing information, understand the methods of investigation, learn to collect, sort out, describe and analyze data, and understand the significance and role of statistics. The content of students' learning in this unit is mainly to investigate, record and sort out the results, which is intended to make students realize the rationality of sampling survey and the diversity of recording methods. Learn to record data by drawing "orthography" to make the results easy to sort out.
3. Analysis of academic situation: Students have already learned the preliminary knowledge related to statistics, such as comparison and classification, which laid the foundation for further study, investigation, record arrangement and simple data analysis of this unit. There are many life scenes related to statistics in daily life, but the students didn't find them. Teachers need to guide students to learn and experience in class: "There is mathematics everywhere in life" and "Mathematics comes from life".
3. Teaching emphasis: understand the rationality of sampling survey under specific circumstances and fill in the statistical table correctly.
Teaching difficulties: cultivate students' practical ability, analytical ability and cooperative consciousness.
4. Teaching objectives: According to the teaching content and teaching focus, the following teaching objectives are formulated:
(1), initially understand the significance and function of statistics, learn the method of collecting data, and be able to fill in simple statistical tables.
(2) The data can be simply sorted according to different requirements.
(3) Cultivate students' observation ability and practical application ability.
Second, oral teaching methods
In teaching, the class adopts "guided inquiry" teaching. Starting from the problems around students, under the guidance of teachers, students explore problems independently and use previous knowledge to solve problems.
Third, theoretical study.
In teaching activities, we pay attention to the teaching process, so that students can feel in discussion, gain in understanding, learn in learning and innovate in learning. Take the initiative to acquire knowledge, but also feel the necessity of cooperation.
Fourth, talk about the teaching process
(A), create a situation
At the beginning of this class, teachers create situations to arouse students' desire to learn new knowledge and stimulate their learning motivation with their existing life experience. So I chose four colors that my classmates are familiar with, which one is suitable? The introduction of making school uniforms has aroused students' enthusiasm for learning.
(2) Explore new knowledge
1. When I impart new knowledge, I intentionally create problems and raise my hand to investigate. Give students ample time and opportunity to express their opinions, explore survey methods, and learn to conduct sampling surveys through discussion and understanding the rationality of sampling survey methods.
2, according to the actual situation to solve the problem
In the statistics of two people who choose to attend the story meeting, guide students to experience the diversity of data recording methods. In these methods. Take the method of drawing "positive" to collect data, and highlight the "positive" collection method. My design enables students to internalize knowledge in the process of continuous thinking, and at the same time, it also forms certain skills; Then use the data collected by the students to make statistics. Therefore, the teaching of this link allows students to experience the whole process of collecting, sorting and drawing. Cultivate students' awareness of problem-solving and cooperation in the learning process. At the same time, it also enables students to receive education of unity and mutual assistance.
(3) Expand the application
In order to reflect the use value of teaching, let students go for a spring outing. Then fill in the statistical table according to your own statistical data. This link is to apply statistical knowledge to solve practical problems and feel the necessity of learning statistical knowledge after students master statistical methods, so that students can realize that mathematics comes from life and serves life, and enhance their ability to apply mathematical knowledge.
(4), class summary
What did you learn from this course? Students summarize by themselves, and cultivate students' ability to summarize and abstract. At the same time, it also cultivates students' self-evaluation consciousness.
In a word, this class is conducted under the new concept of quality education, and strives to highlight students' dominant position. Students form statistical consciousness in the process of participating in learning, feel the connection between mathematics and real life, and find that there is mathematics everywhere in life, which comes from life, is applied to life and serves life, thus cultivating students' great interest in learning mathematics.
