ABSTRACT Computer Science (CS) curricula are being adopted worldwide. However, the lack of prior teaching training within this area means that we have an urgent need to provide teacher professional development. Best practice teacher professional development motivates us to construct interactive and sustainable models of professional development. However, there are challenges in doing this at the scale that we need and with the resources that are available. In this paper, we describe an ecosystem-based approach to supporting teacher professional development, aligned with best practices and with teachers’ and schools’ needs. An ecosystem approach operates under the coordination of a governance model, features a central hub and conceptualises the relationships of the organisations as a network. Ecosystems are underpinned by value co-creation, shared logic and can be non-geographical. We believe an ecosystem view of a teacher professional development program supports sustainability, authenticity and flexibility in how teachers engage with professional development, positioning teachers as co-contributors.

计算机科学中教师专业发展的生态系统方法

摘要 计算机科学 (CS) 课程正在全球范围内被采用。然而，在这方面缺乏先前的教学培训意味着我们迫切需要提供教师专业发展。最佳实践教师专业发展激励我们构建互动和可持续的专业发展模式。然而，以我们需要的规模和可用的资源来做到这一点存在挑战。在本文中，我们描述了一种基于生态系统的方法来支持教师专业发展，与最佳实践以及教师和学校的需求保持一致。生态系统方法在治理模型的协调下运行，具有中心枢纽，并将组织的关系概念化为网络。生态系统以价值共创为基础，共享逻辑，可以是非地理的。我们相信教师专业发展计划的生态系统观点支持教师参与专业发展的可持续性、真实性和灵活性，将教师定位为共同贡献者。
