Why interactive learning environments can have it all: resolving design conflicts between competing goals

摘要

This report on a methodology for designing interactive educational software focuses on the different educational goals of various stakeholders and the process of creating software that reflects the relative importance of each goal. To resolve conflicts between goals, the authors establish a goal hierarchy and experiment with parametrics and cross-iteration. (Parametric experimentation involves running a test that specifically compares two strategies, while cross-iteration experimentation uses a series of tests to compare different design choices.)
