Analysis of the Mid-term Examination Paper in the First Volume of the Sixth Grade Mathematics I. Analysis of the Content of the Examination Paper;
The content of this mid-term exam is Unit 65438 +0-3 of Book 11 of Primary Mathematics. The main characteristics of this paper are moderate difficulty, light questions and emphasis on testing students' understanding and mastery of basic knowledge. This proposition is based on teaching materials, pays attention to process and method, embodies application, has appropriate questions, comprehensive scope and appropriate difficulty, and provides a platform for different students to achieve different development in mathematics.
1, basic knowledge.
Fill in the blanks in the test paper. Investigate students' mastery of basic knowledge and basic concepts from different aspects. Judging from the answers, some students' basic knowledge is not solid. First, students are not careful in examining questions; second, students have not mastered the basic knowledge; third, students study too hard and cannot solve problems flexibly. For example, the ninth question in the blank: 20 kg is more than 16 kg () and less than 20 tons.
2. Calculation part.
In this exam, the students' calculation results are not ideal, and almost all students lose points in calculation to varying degrees. Especially for students below the average score, the calculated loss rate is higher. Individual students with learning difficulties can't calculate. It can be seen that we are still extremely lacking in this respect.
3. Application questions.
This time, the students completed the application problem well. First, the problem is not particularly difficult. Second, it also shows that students' problem-solving ability is not too bad. However, students below the average level will not use what they have learned to analyze and deal with problems, let alone solve them. Especially to solve practical problems in life, which requires me to further reflect on my teaching.
Second, the existing problems:
Students don't have a solid grasp of basic knowledge, and they don't develop good study habits, which is manifested in not carefully examining and answering questions. Most students are too careless in calculation, don't take the exam and lose more points. We can't use what we have learned flexibly to solve practical problems, and our ability to analyze and solve problems needs to be improved.
Third, improvement measures:
1. Pay attention to students' understanding and mastery of basic knowledge and practice basic knowledge and concepts in different ways. Pay attention to creating rich teaching scenarios, stimulate students' interest in learning, and fully mobilize students' enthusiasm for learning in practice.
2. Improve teachers' teaching methods and students' learning methods, carefully study textbooks before class, grasp the difficulties and difficulties of textbooks, use textbooks rationally and creatively.
3. Pay more attention to poor students, ask more questions to students who have difficulties in class, encourage them at any time, help them build up their self-confidence, and practice more in class to face all students.
4. Pay attention to students' learning process, let students experience the process of knowledge formation in hands-on operation, and cultivate students' abilities in all aspects.
5. Cultivate students' good study habits.
