From the abstract: "This article introduces a Strategic, Co-created, and Iterative Learning Design and Development (SCILDD) process, based on models drawn from the literatures of instructional design, design-based thinking, and design-based research. SCILDD includes five essential design components: the initial establishment of strategy, the evolution of that strategy throughout the process, iterative cycles of development, co-creation with target learners, and three clear phases of work that approximately align with analysis (A), design and development (DD), and implementation and evaluation (IE). When utilized together, these components function to leverage the benefits of previous models while mitigating their challenges. SCILDD is intended to invite flexibility and adaptability while maintaining strategic focus, to support design processes situated within a wide range of contexts. The Classroom Pivotal Response Training (CPRT) case study illustrates the application of SCILDD to create (a) a web-based tool to help teachers determine which CPRT components should be prioritized for individual students or instructional settings, and (b) a virtual training module to allow hands-on application of CPRT concepts while supporting large-scale training tailored to teachers and paraprofessionals. This initial application of SCILDD resulted in products perceived to be engaging, usable, and useful. Considerations for future SCILDD application are discussed."
