For over a decade, science educators have lamented the ways in which testing in reading and mathematics has reduced time for science instruction. Blank used 20 years of national teacher and student data to understand how time allocated to science instruction combines with student demographics to shape test scores. The study found a small but significant positive relationship between time on science instruction and performance.
Data from 15 countries suggest that positive parental attitudes toward science are associated with higher student achievement in science. The findings also indicate that socioeconomic status has no effect on the relationship between parental attitudes and student achievement: Poorer students benefit just as much from positive parental attitudes as richer students.
