论商品交换中的权利与义务     

柴艳萍 《首都师范大学学报(社会科学版)》2007,48(5):57-61

财产所有权规定了所有者的合法权利,它要求交换双方互相承认并尊重这种权利。维护自己的利益使之不因交换而受到侵害是自己的权利,尊重他人的利益使之不因交换而减少则是自己的义务。交换中的权利与义务均来自财产所有权。契约是关于交换的微观制度,不仅规定了双方的权利与义务,而且还使得这些权利与义务合法化。为了避免交易的不公平,交换双方应该平等、自由、自主地协商,自愿地交换,以达到公平互利,实现权利与义务的统一。  相似文献   

教育精准扶贫背景下轮岗教师专业引领之困境及其化解     

邹慧明  唐珍妮 《教育文化论坛》2020,12(1):54-61

轮岗教师专业引领指凭借轮岗教师的专业领导力,引领帮扶学校教育理念、课程教学以及教育科研的变革,以促进帮扶学校教师专业发展,培育帮扶学校内生性发展力量,实现薄弱学校精准脱贫。这与旨在从根源上帮助贫困对象脱贫并阻断贫困代际传递的教育精准扶贫理念相契合。然而,在教育实践中,轮岗教师专业引领却遭遇了轮岗教师观念失衡与专业引领胜任力不足,帮扶学校支持性环境与内生性力量缺失,管理部门信息交流平台缺失与制度性保障不到位的困境。化解轮岗教师专业引领困境,需要关注轮岗教师能力精进和角色认同,重建帮扶学校自我变革的主体角色,完善政策导引与制度设计,精准推进轮岗扶贫实践。  相似文献

Traversing the context of professional learning communities: development and implementation of Technological Pedagogical Content Knowledge of a primary science teacher     

Yin Hong Cheah  Ching Sing Chai  Yancy Toh 《Research in Science & Technological Education》2019,37(2):147-167

Background: Professional learning communities are increasingly recognized for their significance in building teachers’ competencies for educational reform. However, the knowledge development cycle of technological pedagogical content knowledge (TPACK) through multiple professional learning communities is not well researched.

Purpose: This qualitative case study investigates a primary science teacher’s TPACK development in the context of two interdependent learning spaces: a joint-school and a within-school professional learning community. The school’s organizational and sociocultural influences on teacher learning are also examined.

Participant: Teacher Sean (pseudonym) embarked on a science innovation project after two years of teaching in a Singapore mainstream school. He was tasked to integrate mobile-based inquiry learning and visible thinking pedagogical approaches, and to pilot the designed lessons for a primary three class.

Design and methods: A case-study approach involving multiple sources of data with cultural historical activity theory as the analytical lens was employed, to unpack the complementary and contradictory interactions across different interrelated activity systems. The purpose was to understand the (mis)alignments within and between the two professional learning communities.

Results: The findings indicate that Sean’s (subject) learning from the joint-school professional learning community to the within-school professional learning community faced multiple tensions that hindered his TPACK development (object). He faced difficulty in manipulating tools (technology and visible thinking routines) to translate the joint-school co-designed lessons into classroom implementation. Additionally, the volatility of the school’s organizational routines (rules) and the lack of communicative leader–teacher partnership (division of labor) did not afford sufficient infrastructure or instructional support.

Conclusions: Interactions between the teacher’s personal and contextual factors inhibited the designed TPACK from being implemented successfully. For ambitious pedagogical undertakings as illustrated in this case, more perceptive and synergistic organizational design thinking is needed to support beginning teachers’ TPACK development.  相似文献

Rethinking Natural Environment Practice: Implications from Examining Various Interpretations and Approaches     

Angie Y. Chai  Chun Zhang  Marilyn Bisberg 《Early Childhood Education Journal》2006,34(3):203-208

Early intervention professionals have implemented natural environment practices for over a decade, despite the continued debate on how to interpret and implement this practice. This article reviews several theoretical frameworks for understanding natural environment practice, and also summarizes different approaches for implementation. The authors present a model for rethinking and redefining natural environment practice in the context of recent approaches.  相似文献
