新制度经济学视野下的教师管理变革

教育发展研究 2009年第2期29卷 36-41页

作者：郭凯广东教育学院教育系副主任副教授广州510303

从新制度经济学的视角考察,我国教师管理制度设计存在着诸多问题,主要表现为:重教师"道德人"假设而轻教师"经济人"假设;重视教师管理的正式制度而忽视非正式制度;重视教师管理制度的约束功能而忽视激励功能;重视政府、学校对教师的管理... 详细信息

从新制度经济学的视角考察,我国教师管理制度设计存在着诸多问题,主要表现为:重教师"道德人"假设而轻教师"经济人"假设;重视教师管理的正式制度而忽视非正式制度;重视教师管理制度的约束功能而忽视激励功能;重视政府、学校对教师的管理而忽视家长的参与等。基于对以上问题的分析,本文指出教师管理变革的方向应包括:承认教师自利行为的正当性;充分利用教师管理的非正式制度;强化教师管理制度的激励功能;扩大家长参与教师管理的权力等。

The analog circuits course is an important elementary course in the electronic engineering specialty. The study mainly introduces the analog circuits course reform in the teachers college of {2., including the reform of theoretical teaching, practical teaching management, and examination of the experimental operations. Practice has proved that rational application of modern educational {2. and the electronic design automation (EDA) software can effectively resolve the "difficult beginning" problem of the analog circuits course, and can closely integrate theoretical teaching with practical teaching. The study also introduces the implemental situations of the practical separation of teaching and testing.

Rare Metals 2002年第3期21卷 182-185页

The complex oxide Dy_(10)W_2._(2.) was synthesized by a solid-state reactionand isolated in cubic symmetry by an X-ray diffractometry (XRD) method. Differential scanningcalorimetry (DSC) measurements show that the compound is thermodynamically stable. The intrinsicthermal expansion coefficients were determined by extra-power powder X-ray diffractometry from roomtemperature to 1000 deg C: linear coefficient alpha-bar = 1.07 X 10^(-5) deg C^(-1) and bulkcoefficient beta-bar = 3.2. X 10^(-5) deg C^(-1). Dilatometry was used to measure the extrinsicthermal expansion coefficient (9.2.X 10^(-6) deg C^(-1)).
