Implementation of China’s New Mathematics Curriculum Reform (2000–2020)

By: Wei Gao,Xianwei Liu

Based on the fieldwork carried out at two elementary schools, Merits School and Pioneer School, in northeastern China, the monograph details how local schools enacted the New Mathematics Curriculum Reform that was launched in early 2000. The trajectory of the reform implementation at each school was plotted out. Both schools resorted to a long-standing quality control mechanism, i.e., teaching norms, to operationalize the reform ideas. The mechanism functioned by placing teachers under measurable supervision and evaluation aligned with the reform. The schools responded to the reform following school people’s raising practical concerns, as well as the established school culture. Merits School arrived at a "two-faced strategy" to cope with the reform. Pioneer School managed to maintain a balance between promoting reform pedagogy and maintaining good test rankings. Both schools marginally involved parents in the implementation of the reform. This study suggests that to achieve success, reformers need to place equal emphasis on the transformation of teachers as well as local policymakers. This book enriches the existing literature on the implementation of mathematics curriculum reform at the school level and brings insights into the schools’ implementation decisions, which will appeal to policymakers, curriculum researchers and administrators.

Robust Filtering for Uncertain Systems

A Parameter-Dependent Approach

By: Huijun Gao,Xianwei Li

This monograph provides the reader with a systematic treatment of robust filter design, a key issue in systems, control and signal processing, because of the fact that the inevitable presence of uncertainty in system and signal models often degrades the filtering performance and may even cause instability. The methods described are therefore not subject to the rigorous assumptions of traditional Kalman filtering. The monograph is concerned with robust filtering for various dynamical systems with parametric uncertainties and focuses on parameter-dependent approaches to filter design. Classical filtering schemes, like H2 filtering and H¥ filtering, are addressed and emerging issues such as robust filtering with constraints on communication channels and signal frequency characteristics are discussed. The text features: · design approaches to robust filters arranged according to varying complexity level and emphasizing robust filtering in the parameter-dependent framework for the first time; · guidance on the use of special realistic phenomena or factors to describe problems more accurately and to improve filtering performance; · a unified linear matrix inequality formulation of design approaches for easy and effective filter design; · demonstration of the techniques of matrix decoupling technique, the generalized Kalman‒Yakubovich‒Popov lemma, the free weighting matrix technique and the delay modelling approach, in robust filtering; · numerous easy-to-follow simulation examples, graphical and tabular illustrations to help the reader understand the filter design approaches developed; and · an account of emerging issues on robust filtering for research to inspire future investigation. Robust Filtering for Uncertain Systems will be of interest to academic researchers specializing in linear, robust and optimal control and estimation and to practitioners working in tracking and network control or signal filtering, detection and estimation. Graduate students learning control and systems theory, signal processing or applied mathematics will also find the book to be a valuable resource.
