第二，学习迁移的"示范"必要性。教育变革的有效性，很大程度上依赖于成功的实践案例和可操作的范 式。教师培训，正是生成、展示和验证这些新范式的最佳场域。当参训教师亲历了一场以学习者为中 心、技术无缝融合、注重过程评价的高质量培训后，他们获得的不仅是知识技能，更是一个鲜活、可复 制的"教学原型"。这个"原型"能够极大降低教师回到工作岗位后实施变革的认知负荷和试错成本。因 此，培训者如何设计学习目标、如何搭建学习支架、如何利用技术工具促进互动、如何进行形成性评估 等，所有这些细节本身就成为极具价值的"教学法"示范。 第三，应对AI风险的"安全试验场"价值。AI技术在教育中的应用潜力巨大，但其风险亦不容忽视，如数 据隐私、算法偏见、信息茧房、思维惰化、过度依赖技术导致的人际关系疏离等。让尚不熟悉AI特性 的教师直接将其应用于未成年人教育，存在不可预知的风险。而教师培训的对象是成年人，他们具备更 强的批判性思维和风险识别能力。在培训过程中，有意识地设置AI应用以及对AI伦理、数据安全、人 机协同边界等议题的讨论和辨析，将会鼓励教师们在实际操作中识别和反思潜在问题。教师培训可以作 为一个"压力测试"环境、在相对可控的条件 ...
