Amid ongoing public speculation about the reasons for sex differences in careers in science and mathematics, we present a consensus statement that is based on the best available scientific evidence. Sex differences in science and math achievement and ability are smaller for the mid-range of the abilities distribution than they are for those with the highest levels of achievement and ability. Males are more variable on most measures of quantitative and visuospatial ability, which necessarily results in more males at both high- and low-ability extremes; the reasons why males are often more variable remain elusive. Successful careers in math and science require many types of cognitive abilities. Females tend to excel in verbal abilities, with large differences between females and males found when assessments include writing samples.

Discovery of Sexuality in Plants

Reiss, MJ ; Sex education and science education in faith-based schools. The key issue for a faith-based school is the extent to which, if at all, its aims, ethos, curriculum, pedagogy and assessment should differ from other schools and the impact this has for its students on their learning, attitudes and dispositions. This chapter explores these issues with specific reference to the teaching of sex education and the teaching of science education. I conclude that the role of religion is somewhat different in science education and in sex education.

Sex in animals has been known for at least ten thousand years, and this knowledge was exploited during animal domestication in the Neolithic period. In answer, Flora Unveiled offers a deep history of perceptions concerning plant gender and sexuality, from the Paleolithic to the nineteenth century. Evidence suggests that an obstacle far beyond the mere facts of pollination mechanisms stymied the discovery of two sexes in plants, and then delayed its acceptance. In myths and religions of the Bronze and Iron Ages, goddesses were strongly identified with flowers, trees and agricultural abundance. During the Middle Ages and Renaissance, this tradition was assimilated to Christianity in the person of Mary.
