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

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

Architecture singularity of a parallel mechanism with five degrees of freedom (DOF) is analyzed. Such mechanism consists of a movable platform connected to the base by five active limbs. Four of them are identical 6-DOF limbs and the last one has the same DOF as the specified DOF of the movable platform. Based on the kinematics analysis, two categories of architecture singularities for such mechanism are proposed. Then the sufficient condition for each singularity is researched. Results show that the mechanism is singular when it employs each category of the proposed architecture, provided that it satisfies the corresponding sufficient condition. It can be concluded that the proposed two categories of architecture singularities should be avoided with the following dimension-al synthesis of such mechanism.  相似文献

高等教育是高职教育的普遍性,职业技术教育是高职教育的特殊性,普遍性的核心要素是“大学意识”。为促进高级技能型人才科学的培养,使未来劳动者的知识、技能与人品结构平衡发展,高职院校有必要树立大学意识。大学意识是培养人追求真理,独立思考能力;是培养、塑造人的“有容乃大”的精神;是衡定孵化社会人的职能。高职的大学意识有其特殊性,重点在于环境陶冶、言传身教和厚德载物。  相似文献
