As a teaching worker, it is often necessary to prepare lecture notes, which is conducive to the improvement of teaching level and the development of teaching and research activities. So what kind of speech is good? The following is a model essay on the popularization of primary school mathematics that I have compiled. Welcome to read the collection.
General handout of primary school mathematics 1 1. Design concept
"Mathematics teaching activities must be based on students' cognitive development level and existing knowledge and experience. Teaching should stimulate students' enthusiasm for learning, provide students with opportunities to fully engage in mathematical activities, and help them truly understand and master basic mathematical knowledge and skills, mathematical ideas and methods in the process of independent exploration and cooperative communication, so as to gain rich experience in mathematical activities. Students are the masters of mathematics learning, and teachers are the organizers, guides and collaborators of mathematics learning. " This is the "Mathematics Curriculum Standard" (experimental draft
Based on the above ideas, we must reform the situation that teachers always "talk" and students passively "listen" in classroom teaching, fully trust students, give them the initiative to learn, and fully mobilize their enthusiasm for learning. To this end, I put forward the teaching reform idea of "guiding inquiry learning and promoting active development" in primary school mathematics teaching, and constructed the vertical structure of inquiry learning classroom teaching, that is, "questioning passion-guiding inquiry-"
Second, the design ideas
(A) about teaching materials
The teaching content of this lesson is the understanding of straight lines and line segments on pages 93-99 of the fourth volume of mathematics in nine-year compulsory education and six-year primary school. In this lesson, students will understand the basic characteristics of some simple geometric bodies and plane graphics, further learn the methods of graphic transformation and object location, and develop the concept of space. Straight line and line segment are the initial concepts in the basic knowledge of geometry, and they are also the basis for further study of plane graphics. The Curriculum Standard of Full-time Compulsory Education points out that in this class, students should pay attention to exploring the relevant space in the real world. Attention should be paid to make students gradually understand the shape, size, positional relationship and transformation of simple geometry and plane graphics through observation, operation and reasoning. Attention should be paid to developing students' concept of space by observing objects, knowing directions, making models and designing patterns.
(B) on the teaching objectives
According to the design concept and teaching content of this course, combined with the actual situation of students, I have formulated the following teaching objectives:
1, so that students can know straight lines and line segments, know their characteristics, and learn to draw straight lines and line segments initially.
2. Let students learn to measure line segments and draw line segments with specified length.
3. Cultivate students' preliminary concept of space.
The teaching focus of this lesson is to know straight lines and line segments, measure line segments and draw line segments with specified length.
The difficulty in teaching is to understand the characteristics of straight lines.
(3) About the teaching process
In order to embody the design concept of this course, I independently constructed the basic teaching mode of inquiry learning classroom teaching, that is, "questioning passion-guiding inquiry-application improvement-exchange evaluation"
1, doubt passion:
Living and active problem situations can easily stimulate students' interest and problem awareness, so that students have a positive attitude of exploring and solving problems independently. In the tutorial, students can show a stick figure in a corner of the campus environment where students live, organize students to classify the lines in the stick figure, and lead to the topic of "straight line".
2, guide the exploration:
When students have the desire and interest to explore, teachers should consider how to provide appropriate conditions, guide students to explore knowledge through observation, operation, thinking and communication, experience mathematical ideas and methods, and emphasize students' ability to establish a sense of space, symbols, mathematics and recognize structures and laws. Teachers only guide and participate in learning, leaving students with vivid scenes to learn mathematics. In the new curriculum teaching, I organize students to know straight lines and laws through observation, thinking and communication.
3. Application improvement:
Learning mathematics knowledge is not an end. It is important to use it to solve practical problems in life, realize the value of mathematics in life, experience the fun of learning mathematics, gain interest and confidence in learning mathematics, and know how to use mathematical methods to explore problems and solutions when encountering problems, thus gradually forming the habit of independent exploration and the spirit of bold exploration. In this session, I ask students to find the line segments in life and distinguish which line segments an object is composed of, as well as other situational problems closely related to life.
4. Exchange assessment:
Students gain new knowledge and experience through independent inquiry learning, which is all-round development, both cognitive and emotional, and then guide students to exchange feelings and experiences happily in activities and exchange views and opinions through exchange evaluation. On the one hand, every successful experience can be transformed into common wealth and become a key factor affecting other students. On the other hand, students should always check the target requirements in the evaluation process. Form a self-feedback mechanism, know yourself in group communication, and learn to evaluate others' learning, such as teaching. Finally, I designed a question: through the study of this class, each group should exchange your gains and feelings, how is your performance, and tell everyone about your gains and feelings.
Third, the teaching process (see the courseware for related graphics)
(A) doubt passion (the use of life situations, leading to math problems)
1, multimedia shows a picture depicting a corner of the campus, including rockeries, running water, the sun, birds, teaching buildings, small trees and various flowers.
2. Guide the students to appreciate the pictures, feel the beautiful campus, stimulate the emotion of loving the school, and then remove the color and turn it into a line drawing.
3. Guide the students to find out what this picture is made of through careful observation. What's the difference between these lines? Can you classify them? (Group discussion completed)
4. Report: Take a flower as an example. Ask the students to classify the lines. Multimedia display flowers are getting bigger and bigger, and lines are classified by name. Under the guidance of students, the lines jump into the corresponding boxes, and the straight lines and curves are marked below the boxes respectively.
5. Lead topic: A straight line like this is a straight line (blackboard writing). Today we will learn this straight line.
(2) Guiding exploration
1, know the straight line:
(1) Understand the characteristics of straight lines:
The courseware shows the scene photos of mother knitting a sweater, highlighting the winding wool scattered on the ground. Q: What shape is it? The teacher straightened it like this. Can you give it a name? (blackboard writing: straight line) This is a straight line. What are its characteristics? The teacher stretched the wool bit by bit and asked, "Can you stretch it?" (Right) Now the teacher can't reach it alone. Who will help the teacher? Please ask two students to come up and pull the teacher and ask, "can you stretch?" If it keeps stretching, please imagine where it can be pulled? " From this, we can draw a feature of straight line: infinite extension (blackboard writing: infinite extension). Does it have an end? Another feature of the drawn straight line: endless point (blackboard writing: endless point)
(2) Draw straight lines: Since straight lines are so long, can you draw them all? The student replied, "No", so we only draw a part of a straight line. Please try to draw a straight line.
(3) Students report and exchange tools and methods for drawing straight lines.
(4) Judging a straight line (courseware presentation): Please carefully observe which one is a straight line? Which one is not a straight line?
(5) Have you ever seen a straight line in your life?
2. Know the line segment:
(1) Understand the characteristics of line segments:
Just now, a child said that the edges of many objects are straight, but they have endpoints. What is this? The courseware shows the photos of the stay cables of Yangpu Bridge (some people say it is a line segment, so they write on the blackboard: no one answered the line segment, but the teacher said)
Please look at the big screen: this is a straight line. Point two points on a straight line. The part between these two points is called a line segment (blackboard writing: line segment). The teacher draws a line segment.
(2) Guide students to observe and discuss: What are the similarities between line segments and straight lines? What's the difference between them? The characteristics of the line segment are obtained: the length is limited and there are two endpoints.
(3) What objects with line segments have you seen in your life?
3, measuring line segment
(Transition) From the study just now, we drew a line segment, knowing that the line segment has a length and can be measured with a ruler and other tools.
(1) Please measure the length of the math book. Don't be busy measuring, first estimate the length of the book and write it beside it (the teacher asked several children to say the estimated length). So how many centimeters is it? Let's measure it.
Good morning, judges and teachers. I am the candidate _ _ _ _.
Oral class:
Today, the topic of my speech is "_ _ _ _ _ _ _". First, let's go to teaching material analysis.
Teaching material analysis:
This lesson is from _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
1, this lesson is divided into _ _ _ _ parts, namely _ _ _ _ _ _ _ _ _ _ _
This lesson runs through the period after _ _ _ _. The whole teaching is the basis for students to operate _ _ smoothly and quickly, and it is also an important link to form students' reasonable knowledge chain. (This article is basically universal)
3. This class is exposed to _ _ _ _ _ _ _ and _ _ _ _ _, which is of great significance for future study.
4. This lesson is the key to further study _ _ _ _ _ _ _ on the basis of studying _ _ _ _ _.
(You don't need to say all the above four items flexibly. You can refer to the sentences in the preface, mainly about the significance of learning this lesson. Next, let's talk about the teaching objectives of this class.
Teaching objectives:
xxx
Knowledge goal:
1、
2、
(that is to say, the knowledge points to be talked about in this class are also the key and difficult points. )
Ability goal:
1, through the combination of lectures and practice, cultivate students' ability to deal with _ _ _ and solve problems.
2. Group study to cultivate students' ability to communicate and cooperate with others.
3. Improve students' ability to analyze and solve problems by setting problem situations.
(Select competency goals as needed)
Emotional goals:
1, cultivate students' earnest and meticulous learning attitude.
2, through the process of finding and solving problems, cultivate students' cooperative spirit, enhance students' thirst for knowledge and enthusiasm for learning computers.
(For the teaching objectives, due to the short time, there is no need to divide them into these three objectives, just say three points. )
When we analyze the teaching materials and understand the teaching objectives, it is not difficult to understand the key points and difficulties of this lesson.
Important and difficult
Key points:
Difficulties:
(For the key points and difficulties, just say the content of this lesson. You can refer to the topic of this lesson and the topic of each part. )
So, how should we finish the task of this lesson? Let's talk about the teaching methods and learning methods of this class.
Teaching methods:
1, an example, combined with the method of guiding inquiry to stimulate students' interest in learning.
2. Teachers speak well and students practice more, which embodies the teaching principle of taking students as the main body and teachers as the leading factor.
3. Use analogy to guide students to find problems and learn independently, so as to experience the happiness of acquiring knowledge independently.
4. Break through the key and difficult points through "teaching", "learning", "releasing" and "receiving".
(Choose any teaching method as needed. Just two or three. According to the schedule. )
Teaching and learning learn from each other. I adopted two main learning methods in this course.
Studying law:
1, active learning method: ask questions with examples, so that students can gain perceptual knowledge, and at the same time, teachers can explain them in simple terms, inspire students to think positively, explore knowledge actively, and cultivate students' comprehensive ability of thinking and imagination.
2. Feedback remedy method: In practice, pay attention to students' feedback on learning, so as to achieve "helping the excellent and helping the poor to meet different needs."
Finally, talk about the teaching process of this class.
Teaching process:
This class is held in a multimedia classroom, and the teaching AIDS needed are teachers' computers-students' computers, projectors, blackboards, etc.
I divide this lesson into three parts.
It takes about 5 minutes to conduct the lead-in part, mainly to review and introduce new lessons.
It takes about 20 minutes to perform the body part. Mainly through the combination of lectures and practice to complete the study of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
Finally, the conclusion is about 5 minutes, mainly summary and homework.
In other words, summarize this lesson and assign homework.
(1, regarding the combination of lecture and practice, if it is a theoretical class, practice means doing exercises, if it is an operation class, it is practical operation on the computer.
(2) I am assigned according to a class of 40 minutes, which needs to be verified.
(3) The general pattern is as follows, which can be selected according to the time requirements.
(4, the voice must be loud, and the speed of speech cannot be too fast. In view of the teaching objectives, key points and difficulties. You should highlight the vocabulary of the course flow. But don't waste time writing on the blackboard.
(5) Pay attention, occasionally look at the judges and make eye contact.
Finally, say "the lecture is over"
If you try to talk, lead out this lesson, and then write the title of this lesson on the blackboard conveniently. Writing is clear and powerful.
If you think you can't finish the whole class, you can say that I will mainly talk about _ _ _ _ today. Because there are no students, so don't be too scattered, have ideas. If you can show the process of your communication with students, show it once, otherwise, tell your own directly.
