Digital Transformation in Teacher Development: Platformization, Ecologization, Practicalization

Based on the analysis of the digital foundation and transformation demands of teacher development, the paper proposes a logical architecture of teachers’ digital learning from the perspective of 70- 20-10 model for learning and development, including self-learning based on platform resources (10%), blended learning based on collaborative support (20%), and embedded learning based on work scenarios (70%). Then, a pyramid model of evaluation and governance for teacher development needs that is compatible with the three types of learning paradigms is proposed, i.e., focusing on using teacher portraits to evaluate learning behaviors, using skills certification to evaluate knowledge and competencies, and focusing on ethics to promote practical wisdom. Finally, to support the transformation of learning paradigms plus evaluation and governance, this paper proposes an action architecture of service upgrading for digital transformation in teacher development, namely, creating a multi-level coherent online learning architecture for platformization, creating a seamless learning space with multi dimensional integration for ecologization, and leading the transformation from just-in-time learning to just-in-need practice for practicalization, ultimately realizing a leap of teachers’ practical wisdom.
