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
Variables • Define your own variables 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
