Description

The report proposes a taxonomy of structures, described as the overarching forms that systems of multiple feedback loops take toward a larger goal. In a generator, one party sits at the center of multiple concurrent feedback loops coordinating outputs; amplifiers elevate one community's knowledge to a broader field with loops on only one side; aggregators bridge a small set of parties and a larger set with loops on both sides; activators have no central party and no single agreed output; catalyzers similarly lack a central party but aim to influence the field at large.

Design Implications

Context

Requirements

• Structures are idealized and generalized forms; in practice they are likely to be more complex and less clear cut given shifting goals, outputs, and participants

Constraints

• Feedback loops exist across, but not directly correlated to, common modes of engagement such as projects, networks, hubs, advisory boards, and communities of practice

Target Learners

• Education innovation organizations designing multi-partner collaboration

Target Learning Objectives

• Selecting organizing structures for co-design, dissemination, community-building, and field influence

Claims

• In the Learner Variability Navigator case, feedback loops across multiple partners generated an output of need that the authors say simple surveys may not have produced [+W]
• In the Maker Learning @ Home cohort, feedback loops with cohort members redefined the initiative's outputs and goals [+W]
• Some initiatives fit no single generalized structure: the OER for Racial Justice project required a novel generator-plus-catalyzer combination [+W]

Related Theories

• Six participant roles in feedback loops: translators, facilitators, users, informants, advisors, designers
• Feedback loops: purposeful, bidirectional, iterative interactions that transform knowledge, actions, or goals

Examples

• Identify feedback loops in your organization by sourcing, evaluating, and validating case studies
• Prefer feedback loops over one-directional feedback systems when direct benefits for all participants matter
• Integrate co-design and continuous feedback loops into AI evaluation processes
