音乐表演中的内心听觉

内心音乐听觉是音乐活动中的一种心理现象。内心音乐听觉与人的音乐知识经验的积累、对音乐感性体验的质量以及人的音乐审美情感都有着直接、内在的联系,是人在音乐表演活动中逐步培养建立起来的,是音乐表演活动中必须具备的心理基础和能力。内心音乐听觉发展水平的高低,直接影响着音乐表演等音乐表演活动的质量以及表演灵感的产生。内心音乐听觉在音乐表演中起着至关重要的作用。本文拟对内心音乐听觉这一心理学现象进行剖析,在此基础上提高内心音乐听觉能力。

Research-based teacher education? Exploring the meaning potentials of Swedish teacher education

In this article, we explore the meaning potentials of teacher education in terms of the significance of a research-based approach and the different pedagogic identities that such an approach implies. The study’s aim is to examine the important factors for education to be considered research-based and to identify and analyse the research base of teacher education in Sweden. The results from the analysis of a large number of course documents and from a survey administered to teachers and students in four teacher education programmes indicate that the emerging potential meaning is that teacher education is generally a strongly framed professional education with a relatively weak and adapted research base. The analysis of the classification and framing of disciplinary content and pedagogy in the Swedish teacher education curriculum points at different pedagogic identities emerging from the different meaning potentials that are made available to the students. We argue that a thorough understanding of research-based teacher education needs to be grounded in both course content and its research base as well as other possible pedagogical aspects of research-based education; the education as a whole must be included in the concept of research-based education.

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.
