This document introduces the 5 Strands + 1 Model for modeling ICHK students. The 5 strands are: Mindset, Learning Zone, Psychosocial Development, Cognitive Disposition, and Interpersonal Relationships. Each strand draws from theories in educational psychology. Mindset refers to Carol Dweck's theory of fixed vs. growth mindsets. Learning Zone draws on Vygotsky's zone of proximal development. Psychosocial Development relates to Erik Erikson's stages of development. Cognitive Disposition comes from Egan's zones of understanding. Interpersonal Relationships is informed by Berne's PAC model and scripts. The model aims to provide a holistic understanding of students by considering their development across these interconnected dimensions.
