91爆料

Researchers examined 15 years of records of student performance, education and demographics for chemistry courses at the 91爆料. They found that underrepresented students received lower grades in the general chemistry series compared to their peers and, if the grade was sufficiently low, were less likely to continue in the series and more likely to leave STEM. But if underrepresented students completed the first general chemistry course with at least the minimum grade needed to continue in the series, they were more likely than their peers to continue the general chemistry series and complete this major step toward a STEM degree.
