论教学“去关怀”现象及其克服

教育理论与实践 2024年第7期44卷 45-51页

作者：伊娟徐继存高嵩山东师范大学教育学部山东济南250014

教学关怀是教师在教学目标设计、教学内容组织、教学方法选择过程中对学生发展给予关爱情感的行为,内含着教师与学生情感互通关系的双向建构。然而,以忽视学生发展的推断需要、敷衍学生发展的明示需要为表征的教学“去关怀”现象导致了... 详细信息

教学关怀是教师在教学目标设计、教学内容组织、教学方法选择过程中对学生发展给予关爱情感的行为,内含着教师与学生情感互通关系的双向建构。然而,以忽视学生发展的推断需要、敷衍学生发展的明示需要为表征的教学“去关怀”现象导致了教师职业情感消退,学生学习思维趋同,师生交往关系紧张。基于社会学中“现代性”的相关理论来看,当代功利主义的干预、技术理性的宰制、教育权威的异化成为这种现象萌生、发展的温床。教学关怀的回归亟待孕育教学情感,唤醒关怀情意;健全教学理性,理清关怀需要;开展教学对话,构建关怀关系。

Network virtualization can effectively establish dedicated virtual networks to implement various network ***,the existing research works have some shortcomings,for example,although computing resource properties of individual nodes are considered,node storage properties and the network topology properties are usually ignored in Virtual Network(VN)modelling,which leads to the inaccurate measurement of node availability and *** addition,most static virtual network mapping methods allocate fixed resources to users during the entire life cycle,and the users’actual resource requirements vary with the workload,which results in resource allocation *** on the above analysis,in this paper,we propose a dynamic resource sharing virtual network mapping algorithm named NMA-PRS-VNE,first,we construct a new,more realistic network framework in which the properties of nodes include computing resources,storage resources and topology *** the node mapping process,three properties of the node are used to measure its mapping ***,we consider the resources of adjacent nodes and links instead of the traditional method of measuring the availability and priority of nodes by considering only the resource properties,so as to more accurately select the physical mapping nodes that meet the constraints and conditions and improve the success rate of subsequent link ***,we divide the resource requirements of Virtual Network Requests(VNRs)into basic subrequirements and variable sub-variable requirements to complete dynamic resource *** former represents monopolizing resource requirements by the VNRs,while the latter represents shared resources by many VNRs with the probability of occupying resources,where we keep a balance between resource sharing and collision among users by calculating the collision *** results show that the proposed NMAPRS-VNE can increase the average acceptance rate and network revenu

Gold nanoparticles （GNPs） have been widely used as probes and nanomaterials in certain biological and biomedical fields thanks to its special physical and chemical properties. However, it is still difficult to characterize GNPs-bioconjugates in solution, which has greatly limited further bioapplications of GNPs. In this study, we reported a single particle method for characterizing GNPs- biomolecules in solution using resonance light scattering correlation spectroscopy （RLSCS）. The interaction of GNPs with bovine serum albumin （BSA） and thiol-modified oligonucletides were investigated.

作者： Li Wen Shao Chao Qing Dong Xiang Yi Huang ji cun Ren College of Chemistry ＆ Chemical Engineering Shanghai Jiaotong University Shanghai 200240 China

In this work, the capillary electrophoresis mobility shift assay （CEMSA） was first adopted to study the interaction of protein with quantum dots （QDs）. In this study, bovine serum albumin （BSA） and CdTe QDs were used as model samples. We observed that BSA was facilely adsorbed to CdTe QDs surface, and the QD-BSA complex was formed by a 1：1 stoichiometric ratio. A value of 2.17 4-0.27 × 10^6 mol^-1 L^-1 （at 25 ℃） for the association constant was obtained by CEMSA.
