Creativity, a phenomenon whereby something new and valuable is formed by a subject in a given context, plays a critical role in specific phases of learning activities. Here, we aim at analyzing creativity in the precise context of ill-defined problem-solving tasks, as it can be experienced during learning activities. This study aims to contribute to a better understanding of creativity within ill-defined creative problem-solving (CPS) tasks, including complex problem solving, through a multi-disciplinary approach using computational and neuro-cognitive formalisms. This approach allows us to propose a multi-factor theoretical description of such cognitive human activities. Based on this, we aim to operationalize a computational framework of creative processes during CPS learning tasks. We focus on an ill-defined CPS task performed by a unique learner, while even in this case sociocultural perspectives have to be considered to model prior knowledge and situational awareness aspects..
