509 Diamond, LisaCareful what you ask for: reconsidering feminist epistemology and autobiographical narrative in research on sexual identity developmentFeminist theory has had an undoubtable but inconsistent influence on developmental psychology. Although feminist perspectives have productively challenged developmental models centered on male experiences (Gilligan 1982) and have called attention to socialization practices that reproduce systemati...Feminism; Epistemology; Autobiography2006
510 Battin, Margaret P.Cases for kids: using puzzles to teach aesthetics to childrenNothing stupefies kids (I have in mind young people, though the same is true of many adults) as quickly as long-winded, jargon-filled, highly abstract theoretical discourse, especially when it seems to have no immediate utility. Kids like fun. They like play; they like games; they like challenges an...Aesthetics; Education; Children; Puzzles1994
