Early career teachers’ sense of professional agency in the classroom: associations with turnover intentions and perceived inadequacy in teacher–student interaction

Teachers’ capacity to learn intentionally and responsively in the classroom is particularly vulnerable during the first years in the profession. This study investigated the interrelations between early career teachers’ turnover intentions, perceived inadequacy in teacher–student interaction, and sense of professional agency in the classroom. The survey data were collected from 284 in-service teachers with not more than 5 years of experience and analysed by structural equation modelling (SEM). The results showed that the negative relation between turnover intentions and early career teachers’ sense of professional agency was completely mediated by perceived inadequacy in teacher–student interaction. The results indicate that experiences of insufficient abilities to solve pedagogically and socially challenging student situations have a crucial effect on early career teacher’s capacity for adaptive reflection and active transformation of instruction.

初论对话教学的本质内涵

对话教学作为现代教育的一种实践形态，是对传统教学秩序的重新建构，体现了一种全新的教学理念。而对话究其本质，它是人类生命存在的基本方式，是教育双方在平等互动基础上的积极建构，它以人的发展为着眼点，进行的是生命的建构。较之以往的教学，对话教学更符合人的规律，更贴近人性，因而在当今的教育实践中表现出了独特的价值。     

聚偏氟乙烯与无规-聚甲基丙烯酸甲酯相容性的研究

本文证明了PVDF与at-PMMA共混物中两者之间非常弱的相互作用 .随着PVDF质量分数的提高 ,共混物显示出更为异相的性质 .通过红外光谱的示差扫描技术 ,减去共混物谱图中PVDF和at-PMMA的谱图 ,显示在高PVDF含量时 ,υc=o吸收峰向低波数移动 ,表明它们之间的相互作用存在于PMMA的羰基和PVDF的H原子之间 .接触角测量表明随着PVDF含量的提高 ,膜的憎水性增强 .当PVDF的含量超过 30 % (质量 % )时 ,对水的接触角大于 90° ,显示了优异的憎水性 .但是 ,膜可以被正己烷完全润湿 ,因而对正己烷的接触角测量不到

Pedagogical Agents as Learning Companions: The Role of Agent Competency and Type of Interaction

This study was designed to examine the effects of the competency (low vs. high) and interaction type (proactive vs. responsive) of pedagogical agents as learning companions (PALs) on learning, self-efficacy, and attitudes. Participants were 72 undergraduates in an introductory computer-literacy course who were randomly assigned to one of four treatments: Low-Proactive, Low-Responsive, High-Proactive, and High-Responsive. Results indicated a main effect for PAL competency. Students who worked with the high-competency PAL in both proactive and responsive conditions achieved higher scores in applying what they had learned and showed more positive attitudes toward the PAL. However, students who worked with the low-competency PAL reported significantly enhanced self-efficacy beliefs in the learning tasks. Also, there was a main effect far PAL interaction type. A proactive PAL had a significantly positive impact on recall. These different results on learning and motivational outcomes suggest that the competency and interaction type of a PAL should be designed according to the desired learning and motivational goals.
