A model of connected growers

Goals model of connected growers 1.      You will learn about the components and structure of dynamic growth models 2.      You will understand the relationship between properties of dynamic growth models and qualitative phenomena such as stepwise growth and temporary regressions 3.      You will be able to build elementary dynamic growth models based on existing research and/or developmental theories To demonstrate the way dynamic systems theory and modeling can be used in the psychology and educational psychology class dynamic systems theory of development

dynamic systems theory of development Parameters Property parameters Growth rate Initial value Level of background resources Timing of the growth process Level of random variation Relational parameters Support Competition precursor dynamic systems theory of development

Example: Fischer’s model of developmental levels in different domains E.g. two levels: stage of operations and stage of relations stage of relations supports stage of operations by level the better your understanding of the relationship between addition and subtraction, the stronger the effect on the growth of the (already established) addition and subtraction skill (operations) Stage of relations competes with stage of operations by change the increase in the understanding of the relation consumes resources that are also needed for the operations of addition and subtraction itself and thus temporary exerts a negative effect on the ability to add or subtract dynamic systems theory of development
