清末江淮官话音系中的声母系统述论

胡垣《古今中外音韵通例》居于官话音系发展的最后阶段,反映的也是清代江淮官话语音系统。《音呼声韵总谱》音系中见、精系声母的腭化,照系声母的独立性,仍母与日母合并等现象,充分表现了清代末期江淮官话声母系统的语音特征。     

二维非静力Boussinesq方程组的初边值问题

Based on the theory of stratification, the well-posedness of the initial and boundary value problems for the system of two-dimensional non-hydrostatic Boussinesq equations was discussed. The sufficient and necessary conditions of the existence and uniqueness for the solution of the equations were given for some representative initial and boundary value problems. Several special cases were discussed.

Talking (fe)male: examining the gendered discourses of preservice teachers

Through the use of feminist poststructural discourse analysis (Baxter 2003 Baxter, J. 2003. Positioning Gender in Discourse: A Feminist Methodology. New York, NY: Palgrave MacMillan.[Crossref] , [Google Scholar]), the author examines the gendered discourses created and reified by a group of preservice secondary social studies teachers (n?=?25). Because gender is socially constructed, it is important for future teachers to examine their own gendered identities in order for them to be able to see how they contribute to the greater society. Findings reveal discourses of ‘having it all', ‘being a superwoman', ‘female struggle', and ‘gender not playing a key role in culture’ being advanced by both male and female identified individuals. Intersections of race and social class with gender added to the complexity of the different discourses. Implications for teacher education are discussed.     

A review of research exploring teacher preparation for the digital age

ABSTRACT

Digital technologies and the Internet are increasing in prominence in schooling systems. As schools and teaching evolve as a result of the integration of technologies teacher preparation will also change. This paper examines research exploring the preparation of teachers for the digital age through a systematic literature review of articles published between 2008 and 2018. The findings provide insight into what has and has not been studied across a range of literature and the alignment with the broader context of digital integration in schools. A focus on digital competencies was identified which was framed in three ways across the literature; generic digital competence, digital teaching competence and an emerging concept of professional digital competence. How student teachers learn to engage in the professional work of a teacher in a digitally infused education system should underpin future research. A model of professional digital competence is proposed.

Ecological influences on teachers’ well-being and “fitness”

The complex and ever-changing nature of teachers’ work challenges their well-being. Teacher well-being and “fitness” includes versatility, mental strength, and commitment to promote effective teaching and learning. In framing this notion, we seek to understand the ecological influences impacting on teacher well-being and “fitness” in the twenty-first century. Drawing on the ecological theory of Bronfenbrenner, this interpretive qualitative study explored the perceptions of pre-service teachers in relation to their teacher well-being and “fitness.” Data were collected from a teacher well-being survey completed by 120 final-year undergraduate pre-service teachers. The survey shed light on themes at four levels: the microsystem (individual and collective capacities); mesosystem (interrelationships between contexts); exosystem (organisational); and macrosystem (societal and legislative influences), compounded by the influence of time at the chronosystem level. These ecological influences were perceived to impact on teacher well-being and ability to be “fit” for sustained performance.
