Recent Developments of Antimony-Based Anodes for Sodium- and Potassium-Ion Batteries

The development of sodium-ion(SIBs) and potassium-ion batteries(PIBs) has increased rapidly because of the abundant resources and cost-effectiveness of Na and K.Antimony(Sb) plays an important role in SIBs and PIBs because of its high theoretical capacity,proper working voltage,and low cost.However,Sb-based anodes have the drawbacks of large volume changes and weak charge transfer during the charge and discharge processes,thus leading to poor cycling and rapid capacity decay.To address such draw...

基层电大教师的专业身份危机

由于电大运作模式的弊端、教师管理的失范、实践理念的偏差和教师专业发展的滞后造成了基层电大教师身份的内部分化和外部泛化的＂身份危机＂。基层电大教师的教学工作和课程开发明显分离,网络教学新的特征和内涵进一步细化了电大教师的角色,教师岗位职能的细化使教师角色同一化,基层电大大量的管理工作进一步泛化了教师的角色,这些都不利于教师的专业发展。基层电大应通过纯化教师角色和控制教师工作量来提高外部认同度,通过建立教师专业发展标准和教学知识评价机制、重视教学理念的先进性、强调教学创新能力来提高内部认同度。     

An analysis of the nature of classroom activities: A comparative study of an immersion English class and a non-immersion English class in the mainland of China

This study was designed to investigate the nature of activities in an immersion English class and a non-immersion English class in the mainland of China, and to find out the differences between these two types of class through data gained from observation and interviews. Spoken discourse analysis was used to analyze the data, where Engeström??s activity complex system was used as the analytical framework to examine the nature of activities in the two types of classes. The results showed that it is the dynamic and situated nature of activity that makes a difference between the activities in these two classes. The interaction among the activity components, the social relations emerging through the process, the use of target language as the main mediational tool, and the subject content revealed in the activities enhance our emic understanding of the nature of activities. Implications can be drawn for English language teaching and for students?? English language learning for the schools in the mainland of China. This study contributes to both immersion education and classroom interaction.
