Purpose: Grounded on components of experiential learning theory (ELT) and self-regulation of learning (SRL) theory, augmented by elements of action theory and script development, the purpose of this paper is to demonstrate the case-based modeling (CBM) instructional approach that stimulates learning in groups or teams. CBM is related to individual and group learning, reflective practices, and the growth mindset. The whole instructional approach is explained in detail as well as unintended consequences and benefits. Design/methodology/approach: The important features of ELT and SRL are presented as well as details of the use of cases (case studies, scenarios, and stories), the creation of case material, and the dynamics of script development. A detailed presentation of the CBM approach with attendant explanation of how the various theories are connected to the steps of the approach is offered. Empirical evidence of the efficacy of CBM is expressed. Findings: The CBM approach may be used effectively in collegiate instruction, employee training and problem solving (in groups), and in other settings. The outputs of the instruction and its processes should result in malleable performance (behavioral) scripts intended to improve both learning and performance. The approach requires high-level involvement and attention to detail. Originality/value: The paper details the confluence of two important learning theories: experiential learning and SRL that result in a formal instructional model. Activities require learning on the individual and group level. The entire instructional model is presented in a way that a practitioner may implement the model. In addition, substantial detail is provided on the construction of case material and the sources of case material.
