First, the teaching objectives of this semester
Through the teaching of this semester, students can master the operation and method of addition, subtraction, multiplication and division of fractions and the solution of fractions. Master the concept of inverse proportional function and image properties; Pythagorean theorem and its inverse theorem; Properties and judgment methods of various special quadrangles; Make students experience the process of knowledge exploration, experience the occurrence and development of knowledge, gradually master mathematical thinking methods in the process of knowledge learning, get interest cultivation and ideological education, and improve students' ability to analyze and solve problems; Further establish the spatial concept of geometric figures; Understand the idea of statistics, the idea of combining numbers with shapes, the idea of equations, and the idea of classified discussion.
Second, teaching material analysis
The content of this semester includes five chapters: fraction, inverse proportional function, Pythagorean theorem, quadrilateral and data analysis. Each chapter is a separate study topic, and there is little connection between chapters. However, the knowledge learned this semester is related to the knowledge learned in primary school, grade seven and grade eight last semester, which is the basis for future study. Therefore, the span of knowledge connection is relatively large, which requires students to review what they have learned frequently to avoid forgetting. Therefore, in teaching, it is necessary to clarify the teaching objectives, key points and difficulties of each chapter in order to successfully complete the teaching tasks of each chapter.
Thirdly, the analysis of learning situation.
Although the eighth-grade students have mastered certain basic knowledge and have certain abilities, the actual foundation of the students in our school is poor, especially in terms of abilities. Coupled with the lack of initiative in learning, students can't actively preview, review after class and finish their homework according to the teacher's requirements, which leads to the ideal learning effect of classroom test students, but the homework handed in the next day is not ideal.
Fourth, teaching measures.
1. The focus of teaching this semester is to strengthen the teaching of basic knowledge and the training of basic skills, and on this basis, strive to cultivate students' ability to analyze and solve problems.
2. Prepare lessons before class. Prepare lessons carefully before class, study teaching materials and curriculum standards, grasp the key points and difficulties of teaching materials, clarify the position of this chapter in the whole, analyze and clarify the internal relations and laws between knowledge, and master the contents of teaching materials comprehensively and deeply. According to the actual situation of students and the requirements of curriculum standards, complete the teaching tasks of each section.
3. Let students get ready, have a deep understanding of students' ideological reality and knowledge and ability level, fully estimate the possible problems when students learn new knowledge, and carefully design teaching procedures and teaching methods according to students' cognitive rules.
4, seriously consider how to help students clear learning objectives, correct learning attitude, stimulate and mobilize learning interest and enthusiasm, and help them solve learning difficulties. Study scientific learning methods and cultivate students to form good study habits. Understand students' learning situation, choose appropriate teaching methods according to students' learning situation, and let students understand and master basic knowledge.
5. Prepare teaching methods. According to the curriculum standards, textbook requirements and students' reality, the overall optimization teaching method is designed to highlight key points, break through difficulties and solve key problems. The application of teaching methods should be in line with students' reality, which is conducive to cultivating students' good study habits, mobilizing students' learning enthusiasm at different levels, and cultivating students' ability to learn, think and solve problems independently.
6. Prepare homework, and assign different homework to different students according to their different learning situations. The workload is moderate, correct the homework in time, track and correct the problems in the homework, carefully evaluate and improve the quality of practice, and the workload should not exceed 20 minutes.
7. Excavate the inherent ideological education factors in textbooks, cultivate students' patriotism and national pride, and mobilize students' enthusiasm for learning mathematics.
8. Classroom teaching. Teaching should face all students, carefully organize teaching, and promote students' all-round and harmonious development through classroom teaching. Establish teacher-student exchanges and develop a new democratic and equal teacher-student relationship. Change the traditional teaching methods. Pay attention to the art of classroom teaching, highlight key points, decompose difficulties, accurately grasp doubts, concise and vivid language, and clear blackboard writing. Make full use of classroom teaching to create interesting situations for students and stimulate their interest in learning. Connecting with real life, let students feel the close connection between mathematics and life and realize the importance of learning mathematics. In teaching, students are the main body, from shallow to deep, layer by layer. In addition, we should pay attention to students with learning difficulties, stand by them more, understand their learning situation, help them solve their learning difficulties in time, and give them more opportunities to enhance their learning confidence in some simple problems. This creates a harmonious and democratic classroom atmosphere, allows students to actively participate in teaching, and fully embodies the student-centered classroom teaching.
9. Measures to improve teaching quality.
(1) Stimulate students' interest in learning and the importance of learning mathematics by creating problem situations and mathematics around them, so that students can understand that mathematics comes from life and is closely related to our life and production, thus making students willing to learn mathematics.
(2) Adopt many teaching methods such as hands-on operation, questioning, inspiration and observation. Increase the initiative and interest in learning, and reflect students' subjectivity.
(3) In order to improve the efficiency of classroom teaching, for some classes with less teaching content, students can be required to preview before class, and teachers can give lectures in class. After completing the necessary exercises, they can spend 10 to 15 minutes in class to test students' mastery of knowledge in class, and then make targeted comments to improve students' learning enthusiasm.
(4) Classroom teaching, so as to be precise. That is, the teaching language is simple and clear, so that every student can understand the teacher's words, and let the students operate by themselves, observe with their eyes and think with their brains, so as to be diligent with their hands, eyes and brains.
(5) Pay attention to students with learning difficulties, do not discriminate against students with learning difficulties, respect, care for and cherish students with learning difficulties, and let them feel the care of teachers and classmates. Set some simple questions for them to answer and enhance their self-confidence. Use lunch break or the eighth period of self-study to help them keep up with the teaching progress. In addition, be patient with them and answer their questions patiently.
Fifth, improve the quality and make up the difference.
For middle and upper-level students, use extracurricular reading materials and extracurricular materials to enrich their minds, increase their knowledge and improve their comprehensive analysis and problem-solving ability through special training. Encourage them to use their spare time to broaden their knowledge and horizons through extracurricular materials or online learning, ask questions if they don't understand, and develop the habit of being diligent and inquisitive, thus improving their abilities in all aspects. Pay more attention and help to students with learning difficulties, ask more simple questions and encourage them in class, so as to enhance their confidence, and use lunch break or other time to give them guidance and let them learn some simple knowledge.
Six, self-improvement
In order to improve their professional level and teaching ability. Seriously study the new curriculum teaching concepts and standards, in-depth study of teaching materials, and improve their teaching ability. Learn Suhomlinski's advice to teachers, successful education and basic skills of effective teaching. Learn advanced teaching methods and improve your teaching level. Participate in political study and business study organized by the school regularly. Participate in teaching and research group activities in time every week. One small print a week, several self-study notes and one problem solving, and insist on learning computer technology every week. In addition, in terms of teachers' morality, we should set an example, love our posts and respect our work, and establish a good image of people's teachers.
Seven. subject study
The research topic of this semester is how to improve students' basic skills. Judging from the learning situation of the eighth grade students, the students in this grade have poor foundation, poor ability, poor ability to master and flexibly use knowledge and low interest in learning. This topic is formulated in view of this situation.
Eight, comprehensive practical activities
Practice activities are carried out by using mathematics activities and topic learning after each chapter in the textbook, which can improve students' ability of hands-on operation, observation, group discussion and cooperation and exchange, and enhance students' interest in learning mathematics.
