A Comparison Research Of A New And An Old Textbooks' Algebra Exercise For The Compulsory Education Mathematics Curriculum Of Junior Middle School

Junior middle schools textbooks of People's educational press is different from the compulsory education Experiment textbooks of Beijing Normal University press, because of the file of guiding principle are The nine-year Compulsory Education full-time Elementary Mathematics teaching outline of Middle school (2000) and The Mathematics Curriculum of the Compulsory Education. The thesis mainly makes a comparison between the two Edition textbook's Algebra Exercise.During the analysis of the Exercise, we take a framework of exercise analysis, to decompounded the exercise on three dimension degree, they are Mathematical feature, Contextual features and Specific requirement. So every exercise has its type, and on each dimension degree, we get a quantity of the exercise. After the quantitative comparison, we found that the quantity of the exercise is reduced, and also have some other changes:(1) On the Mathematical feature, exercise's type from unitary to diversification, and take connection with other subjects or other content of mathematics. Abilities of estimate, suspect has been taken a much more important place. The rate of the "Open-Approach" also have increased. (2) On the problems' background, we know the knowledge connected with the life is more and more important, so take more background and reality content to the exercises. (3) On the aspect of problems' cognition, procedure practice take about half of all the exercises from 70% in the old one. And other types of exercises are increased. The number of exercises of problem solving increased obviously. The quantity of the exercises of required to explain the answers also has increased.For the study, we also give some theoretic analysis to the characteristic dimension degree and the obvious changes between the two textbooks. One side, it can reflect the tendency of problem's compilation, the other side, it will give some reference to the teachers for grasping of the textbooks.And on the comparison's conclusion, we also give some advices for exercise's compilation and collocation.
