These findings are in contrast to earlier results from 1990 that indicate measurable differences favoring males in complex problem-solving, beginning in the high school years.
Janet Hyde from University of Wisconsin and colleagues reported their study results in the journal Science on Friday.
Currently, women are largely absent from the highest levels of careers in mathematics, the physical sciences, and engineering. In the United States, Ph.D. programs in engineering currently average only about 15 percent women, and similar statistics have led to stereotypes (成见)about girls and women lacking in mathematical ability.
Now, it is clear that the general population no longer shows a gender difference in mathematical skills, according to this latest report.
And this new data on academic performance in the United States shows that students are tested frequently on "recall" and "skill/concept" items, but rarely on "strategic thinking"(战略思维) or "extended thinking" concepts.
If standardized tests do not assess (评估)the sorts of reasoning that are crucial to careers in science and math, then the skills may not be taught, putting American students at a disadvantage to students in other countries where testing and instruction focuses on more challenging content. "This is a gap that should be fixed," Hyde said.
