    Gender differences in preschoolers’ understanding of the concept of life
    (SAGE : Journal of Early Childhood Research, 2010-01) Schroeder, Meadow; Graham, Susan; McKeough, Anne M.; Stock, Hayli R.; Palmer, Jaime
    This study investigated gender differences in North American preschoolers’ biological reasoning about the concept of ‘life’. Four-year-olds (M = 4.6, SD = 3.3 months) and five-year-olds (M = 5.6, SD = 3.8 months) were asked about the function of 13 body parts, organs, and bodily processes. Results indicated that the likelihood of mentioning the importance of body parts, organs, and bodily processes for maintaining life or preventing death was predicted by age. A concept of life was more likely to occur in boys rather than girls. Although boys had a greater understanding of life they did not outperform girls in their responses to organ/ body part function. The results demonstrate that gender differences in biological reasoning emerge during the preschool years. Implications for early science education are discussed.

    Teaching preschoolers about inheritance
    (SAGE : Journal of Early Childhood Research, 2016-01) Schroeder, Meadow; McKeough, Anne M.; Graham, Susan; Stock, Hayli R.; Palmer, Jaime
    This study aimed to promote advanced reasoning about biological inheritance in four- and five-year-olds. A total of 78 preschoolers (Experimental n = 40; Comparison n = 38) completed pre- and post-test versions of two biological reasoning tasks. The Experimental condition received 15 lessons on biological inheritance, whereas the Comparison condition received regular story time activities. The results showed that the Experimental group outperformed the Comparison group at post- test. Overall, the results are an encouraging indication that an increased understanding of biological inheritance can be effectively supported in preschool years.
