Learning designers are no stranger to using models—consider ADDIE, SAM, and Merrill’s First Principles, which are widely implemented in the L&D industry. But a less commonly discussed practice is constructing models that help inform design decisions for the learning solutions we create.In this issue of TD at Work, Kristin Torrence:

• Outlines five L&D models

• Describes how the models facilitate an evidence-based approach to design and assessment

• Walks readers through how to develop each model in practice

• Presents case studies for using the models for data-driven decision making

The Tools & Resources in this issue are a modeling preparation checklist and a bonus competency model template.
