Question 2: What are the process teaching objectives, teaching emphases, teaching difficulties, teaching preparation, teaching process, summary, homework assignment and feedback included in the teaching design of primary school mathematics?
Question 3: What are the steps of the first grade mathematics teaching design scheme? The first lesson: understanding plane graphics.
Teaching objectives:
1. Let students intuitively feel the characteristics of various graphics by spelling, swinging and drawing various graphics.
2. Cultivate students' preliminary observation ability, hands-on operation ability and mathematical communication ability.
3. Be able to identify and classify various figures. Teaching focus:
Understand rectangular, square, circular and triangular objects and figures.
Teaching difficulties:
Understand rectangular, square, circular and triangular objects and figures.
Teaching preparation: graphic paper jam, objects, learning tools, etc.
Teaching process:
First, review and explore new knowledge:
1. Do the children remember these graphic friends? (Cuboid cube spherical cylinder)
Can you draw the plane of these figures? The students draw a picture on the paper.
3. What are the characteristics of your painting?
Students discuss and summarize in groups, and finally send representatives to communicate with the class.
Differences: * * Similarities:
The opposite sides of a rectangle are equal and the four corners are straight and flat.
The four sides of a square are equal, and the four corners are straight and uninterrupted.
A circle without an angle is closed)
A triangle has three sides and three angles.
Second, consolidate development:
1. Say, which objects around you are the graphics you have learned?
2. Draw your favorite figure with circle, square, rectangle or triangle?
Comment in groups, and each group shows its own work.
3. Exercise 1 Question 1
Please draw a circle, a square, a rectangle and a triangle. Do you know what color to draw? Discuss and cooperate in groups and report which colors are yellow, blue, purple and red.
4. Make a figure with circles, squares, rectangles and triangles.
Cooperate at the same table, which table is the best? The whole class exchanges and shows.
Question 2: How many circles, squares, rectangles and triangles are there?
Done independently. How do you calculate it? Is there any good way?
Question 4: What is the basic teaching process of mathematics in primary schools? Student-oriented education is designed for students' learning, and it is a kind of quality education advocated and popularized by Professor Guo of Guangdong Institute of Educational Science. Its greatest feature is to highlight students, study, explore and cooperate, to do everything for students, to highly respect students and to rely on them in an all-round way. At present, our school is vigorously promoting the classroom teaching mode of student-oriented education, which has achieved initial results. In this paper, from the perspective of higher mathematics in primary schools, combined with my own teaching practice, I talk about the basic process of mathematics classroom teaching under student-oriented education:
The first link: two minutes before class.
Two minutes before class is a stage for children to show off, which brings them happiness, freedom and growth in these short two minutes. This link is the favorite of teachers and students. The students' confident hosting, wonderful display and rich content are really a feast with all colors, flavors and flavors. The content displayed by students is rich, including ancient mathematical poems, stories of mathematicians, important mathematical news, mathematical idioms, the origin of mathematical symbols and so on. It's really colorful, each with its own merits.
The second link: preliminary operation
The most important link in the classroom teaching of student-oriented education is to let students finish the homework assigned by the teacher. According to students' cognitive characteristics and life experience, design "homework before class" reasonably. Information literacy focusing on cultivating students' ability of information collection, processing and communication has become the basic literacy of every citizen in the new era. Pre-class homework includes two aspects: one is pre-class homework reservation. Teachers should pay attention to clear objectives in the design of homework before class so that students can clearly know what the topic is. A good homework design before class should be as enlightening, open and creative as possible, so that students can be trained in learning methods and thinking ability in the process of doing homework before class, and at the same time, the problems existing in students' self-study process can be exposed and discussed. The second is the homework completed in class. According to the actual situation, teachers move "preview" to the classroom, that is, at the beginning of the class, students are allowed to explore, practice and learn by themselves closely around the learning objectives and according to the teacher's "self-study guidance". At this time, students' learning is the unified action under the teacher's command, and it is the exploration, practice and learning that every student is carrying out. Students study within the specified time, which strengthens the concept of time and effectively cultivates students' autonomous learning ability.
The third link: group cooperative learning
As an idea, student-oriented education is student-oriented, life-oriented, all for students, highly respected and completely dependent on students. Student-oriented classroom, so that every child has the opportunity to innovate, so that everyone's wisdom shine. Group cooperative learning embodies this principle. My teaching process is: 1, showing the requirements of group cooperative learning; 2. The members of a four-person group began to study small research before class, and expounded their views in combination with the deepest feelings of the group members. Team members can complement each other and prepare to report to the whole class on stage. Four-person team members are suitable, and the composition is generally excellent, poor and excellent. Select students with excellent performance and strong management ability as the team leader, and the tasks of the team leader include division of labor, coordination, help and evaluation. The so-called division of labor means that when a group completes a task together, if there is no clear division of labor, students will be at a loss. For example, determine the tasks of the first, second, third and fourth speakers, choose a question after group communication, and then discuss the tasks of each student when preparing the report on the stage. The first speaker in the group is usually the students who are not good at speaking or have poor level, and the excellent ones usually speak last. Coordination means that in the process of division of labor, when a certain task can't give full play to a classmate's specialty and he has the desire to undertake other tasks, the team leader should coordinate. When the students in the group undertake a similar task for a long time and need to cultivate his other specialties, the group leader should coordinate. So every once in a while, I will ask the team leader to change the tasks undertaken by the team members according to the actual situation, so that every student can get various exercises. The task that the study group tells the whole class in math class is generally: 1. What is my example? 2. What is my solution? 3. What should I pay attention to when solving problems? 4. What is the question I don't understand?
The fourth link: group report
It is an important content of a class to reach an agreement in the group and report to the whole class. The requirement of group newspaper is: 1. Every primary school in the group should speak. 2. After the speech, the group leader should undertake the task of communicating and interacting with the students in the audience. After the speech, the group leader will ask: Does anyone have any comments, supplements or questions about our group's report? Then, the group leader should walk off the platform and communicate with other students or groups on behalf of the whole group. 3. The team leader should also undertake or designate him ... >>
Question 5: How to design the teaching process in the primary school mathematics teaching plan? Without comprehensive consideration and careful design when preparing lessons, there will be no effective guidance and dynamic generation in the classroom; Without a plan before class, there is no relaxation in class. Then, under the new situation of curriculum reform, teachers should
Teachers should first make new breakthroughs and innovations in their concepts. It can be said that there will be no breakthrough in the content and method of preparing lessons without a big change in teachers' thinking. We are not only responsible for students' mathematics study today, but also for their lifelong development and happiness. If teachers really set up such a concept, they will pay attention to students when preparing lessons. Only by keeping in mind the new curriculum concept can teachers better position their classroom teaching in preparing lessons and make our classroom teaching keep pace with the times.
To teach a class well, teachers must know ourselves and ourselves, deeply understand the knowledge and life experience that students have mastered before learning new content, foresee various problems that students may have in their study and preset strategies to solve these problems. This can prevent students from being divorced from reality and teaching the content too deeply. Therefore, for students preparing for the exam, it is necessary to understand the basic situation of the class, personality characteristics, learning foundation, reaction to teaching methods, personality quality, dynamic changes and so on.
In preparing lessons, to set a good teaching goal, besides "double basics", we should also pay attention to: (1) Every class should focus on cultivating students' learning interests, habits and methods, and it is more important to implement this main goal than to teach students to master knowledge. (2) Every class should pay attention to the teaching goal of transforming mathematical knowledge into practical ability. When formulating and grasping the learning objectives in class hours, we must focus on the cultivation of students' sustainable development ability, ignore the framework of the double-base objectives and pay attention to the integrity and comprehensiveness of the objectives.
When preparing lessons, we should make clear the key points, difficulties and keys of the teaching materials. Generally speaking, the main feature of key content is that it is widely used and has the most direct and close relationship with future learning. For example, the meaning of multiplying a number by a fraction is widely used in daily life and production. It is the most direct basis for studying the application problem of fractional multiplication in the future, and it is also an important concept to solve the composition judgment of application problems. There is no doubt that it occupies an important position in the whole textbook and is the focus of the whole textbook.
How to highlight the key points in teaching after determining the key points? I think: first, as far as classroom teaching is concerned, the emphasis is on explanation, homework and time. Secondly, as far as mathematical knowledge is concerned, there are generally key points and emphases. When explaining, we should be good at grasping the key points that play a decisive and leading role. When speaking, we should cut in and lead the way, and the key content can be relatively prominent. Thirdly, as far as the rhythm of classroom teaching is concerned, teachers should slow down their intonation and teaching rhythm when explaining key contents. In this teaching rhythm, students can listen to the key points clearly and think clearly.
The difficulty is the knowledge that most students can't easily understand and master. Some contents in primary school mathematics textbooks are abstract and difficult for students to understand. Some contents are criss-crossed; The essential attributes of some contents are relatively hidden; Some embody new ideas and methods; Some show that there is a big gap between old and new knowledge, and so on. This kind of content is difficult for teachers and students to learn. When preparing lessons, teachers should determine it according to the breadth and depth of teaching materials, students' knowledge base and psychological characteristics, so as to achieve the best effect of preparing lessons effectively.
Some contents in the textbook play a decisive role in mastering a certain part of knowledge or solving a certain kind of problems, and these contents are the key to the textbook. As the key to teaching materials, it can often play a breakthrough role in overcoming difficulties and highlighting key points. Once the key of the textbook is handled, the relevant teaching content will be solved.
Choosing the right teaching method to prepare lessons and whether the teaching goal can be achieved depends largely on the choice of teaching method. Take the first lesson of triangle interior angle sum as an example. The teaching goal of this lesson is: 1 Students do it by themselves. Through measuring, cutting, spelling and other activities, they find and confirm that the triangle interior angle sum is 180 degrees, and will apply this knowledge to solve simple practical problems in life. In the process of acquiring knowledge, students should cultivate their innovative consciousness, exploration spirit and practical ability. And through hands-on operation, the sum of the internal angles of the triangle is transformed into a right angle, and the transformed mathematical ideas are infiltrated into students. Students can experience the joy of success and stimulate their active interest in learning. In order to achieve the above teaching objectives, teachers should let students experience the whole process of the formation, development and application of the knowledge that the sum of the internal angles of a triangle is 180 degrees. ......& gt& gt
