The new people's education press, the fourth grade, the second volume, the first guiding ideology of mathematics teaching plan;
The second volume of the fourth grade mathematics textbook is based on the basic idea and the prescribed teaching content of the Mathematics Curriculum Standard for Full-time Compulsory Education (Experimental Draft), and is compiled on the basis of summarizing the research and application experience of the current nine-year compulsory education primary school mathematics textbook. On the one hand, the editor tries to embody the new concept of teaching materials, teaching and learning, and at the same time pays attention to the feasibility of the measures taken. Make the experimental teaching materials innovative, practical and open. On the other hand, paying attention to the relationship between inheritance and development not only embodies the new concept of mathematics education reform, but also maintains the fine tradition of mathematics education in China, making the teaching materials basic, rich and developmental.
Second, the analysis of learning situation:
The students' foundation in this class is uneven, the phenomenon of two-level polarization is serious, and the initiative of learning is far from enough. Of course, there are also many positive students in the class, and there are also many positive and thoughtful students. Judging from the final quality inspection of last semester, students have not mastered the "two basics" knowledge and the ability to solve problems well. Some students have impetuous learning attitude and poor computing ability, which need to be further improved, and their ability to analyze applied problems needs to be strengthened. A few students still need to continue counseling. As far as students' habits are concerned, some students have not developed good study habits. Many study habits need to be improved, such as carelessness, forgetfulness, copying wrong numbers and not using a ruler; There are also some students who lack self-confidence.
Third, teaching material analysis:
This textbook includes: the meaning and nature of decimals, addition and subtraction of decimals, four operations, algorithms and simple calculations, triangles, positions and directions, broken-line statistical charts, mathematical wide-angle and comprehensive application activities of mathematics. Among them, the meaning and nature of decimals, addition and subtraction of decimals, operation rules and simple calculations, and triangles are the key teaching contents of this textbook. Characteristics of textbook compilation
