Learning Systems: Structure, Dual Loops, and the Handover of Design Responsibility

Developmental aims do not become learning conditions by themselves. This article defines learning-systems design as a professional practice: the structured organization, for particular learners and developmental purposes, of knowledge, tasks, support, evidence, and operating conditions, revised in light of feedback. It distinguishes two objects. A personal learning system is the learner's own organization of purposes, a map of knowledge, a network of resources, relationships, tools, and evidence. A designed learning environment is the set of conditions organized by a family, a school, or another responsible party. The long-term task of the environment is to support the formation of a personal learning system, not to make the environment ever denser. Analysis proceeds through four layers: elements, structure, operation, and growth. Seven elements are materials only. Structure consists of five relations: purpose, sequence, proportion, connection, and feedback. The claim that the same elements yield different learning when they are organized differently is a premise of the practice and remains an untested hypothesis. Human growth moves through knowing oneself, understanding the world, choosing and acting, and returning to self-knowledge through feedback. The system that supports this movement cycles through sensing, interpreting, adjusting, and connecting and extending. Endogenous growth is the sustained coupling of these two loops together with a handover of design responsibility from external design, through shared design, toward self-directed design. It is not an increase in the number of activities, nor is it improvement under an unchanged aim. Design principles, system quality, and learner outcomes are judged separately. Equity and access require a minimum version that still stands when resources are scarce. Whether unequal resources are thereby amplified remains to be tested. The article reports no primary data. Its illustrative examples are not evidence. 中文摘要 发展目标不会自行变成学习条件。本文把学习系统设计规定为一种专业实践:面向特定的人与发展目标,对知识、任务、支持、证据和运行条件作结构化组织,并按反馈持续调整。它区分两种对象。个人学习系统是学习者自己组织的目标、知识地图、资源网络、关系、工具和证据。被设计的学习环境是家庭、学校和其他责任主体为学习者组织的条件。环境的长期任务是支持个人学习系统形成,而不是把环境做得越来越密。分析按四个层面进行:要素、结构、运行、生长。七个要素只是材料。结构由五种关系构成:目标、先后、比例、连接和反馈。同样的要素因组织方式不同而产生不同的学习,是这一专业实践得以成立的前提,目前仍是有待检验的命题。人的成长沿认识自我、理解世界、选择与行动、反馈与再认识循环。支持这一过程的系统沿感知、解释、调节、连接与扩展循环。二者的持续耦合,加上设计权从外部设计经共同设计移向自主设计,构成可观察的自生长。自生长不是活动数量增加,也不是在原有目标下把事情做得更顺。设计原理、系统质量与学习者结果必须分开判断。公平与可及要求低资源条件下仍有站得住的最小版本;资源差距是否因此被放大,仍待检验。本文没有原始数据。说明性示例不是证据。 The English PDF is the primary file.
