机能主义心理学:从芝加哥学派到哥伦比亚学派

本文比较了机能主义心理学内部芝加哥学派和哥伦比亚学派在研究倾向上的差异，认为这种差异使心理学研究从心灵主义迈向客观主义并成为一个连续的过程，而机能主义出于这个连续过程的过渡环节。其中艺加哥学派主要是在与构造主义的斗争中确立了机能主义的基本立场和原则；而哥伦比亚学派把研究的侧重点由理论探讨转向对具体问题的研究，因此在具体研究成果的获得和研究方法的拓展方面贡献显著，为日后行为主义的产生奠定了先前基础。

Relating early childhood teachers’ working conditions and well-being to their turnover intentions

High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession.

Understanding teachers’ motivation for and commitment to teaching: profiles of Chinese early career,early childhood teachers

ABSTRACT

To better understand the reasons underlying attrition and the teacher shortage, and to develop ways to attract and retain high-quality teachers in early childhood education, it is necessary to explore teacher motivation and commitment to teaching. Although previous research has investigated various aspects of teacher motivation and commitment to teaching, little attention has been paid to this in the context of early childhood teachers, especially early career teachers. Drawing upon in-depth interviews with 12 early career, early childhood teachers in mainland China, this study aims to examine early career early childhood teachers’ motivation to teach and commitment to teaching in the Chinese context. Four distinct types of early career, early childhood educators were identified: committed passionate, committed compromiser, undecided, and uncommitted. Each of these had unique motives for teaching and different levels of commitment to kindergarten teaching in mainland China. The four types of early career early childhood teachers identified in this study demonstrate the diversity and complexity of teaching motivation and commitment to teaching in the field of early childhood education. The findings from this study can provide implications for policy-makers and teacher educators to enhance novice teachers’ motivation and commitment to teaching in the early childhood context.
