Study On Mathematical Practical Problems In Middle School's Teaching

Mathematical practical problems in senior schools include a widely backgrounds, which comes into every aspect of society. They absorb lots of materials which relate to normal life and focus on the hot matters. These materials must be true and natural. Although the solutions of these problems don't need too difficult knowledge, the marks of the students are less than 15 percent. Many students are afraid of these problems. This may be due to the shortage of the psyological instruction in normal class. Some teachers exaggerate the practical problems rather than analyze them correctly, which brings the students lower marks. This will not meet the object of cultivating children to solve the practical problems.This research begins with mathematical practical problems in high school, studying some problems in mathematical instructions. The following problems are included in this part:Firstly, what problems will exist in teaching the mathematical practical problems?Secondly, what problems will also exist in learning how to solve the mathematical practical problems?Thirdly, what are the effective strategies in teaching the mathematical practical problems?The investigation method, literature analysis method will be adapted. The literature analysis method mainly involves in middle school teaching course, base on these magazine or journals, some articles on applies mathematical practical problems in senior high school, from which some excellent experience and mathematical are adopted so that some effective maths teaching strategies can be achieved, then 129 students and 24 maths teachers are selected in long xi No.1 Middle School As the subjects of the investigation. The thesis analysis some problems confronted by maths teachers and some difficulties faced by senior students in the process of solving applied maths problems.The findings are as follows: some maths teachers are lack of enough basic knowledge and of adequate teaching competence, what's more, they can't explore all kinds of teaching resources related to applied maths problem, and their teaching methods are so dull that their students show no interested in practical maths problem. on the other hand, the students' basic knowledge and skills are not so good. Therefore, psychological barriers, for example, the sense of fear. Also the students have a poor understanding of some applied maths problems.Some effective maths teaching strategies are summed up through this investigation, that is, to begin with broaden students' horizon about applied maths problems; then inhanch students' necessary knowledge and basic skills; next, wipe off the mysteries of practical maths problems and students' psychological barrier; finally, pay more attention to students' understanding of maths practical problems to improve their recognition as well as teaching methods, besides, experience the process of reflection maths problems.
