As a result, comparing the test results of charter schools with local public schools is like comparing «apples to oranges» because they often serve
very different groups of children.
Not only did they find that students in public pre-K were significantly more likely to take the gifted and talented test, regardless of demographic background, but they also found that attending public pre-K may play an important role in helping to reduce test - taking disparities
among different groups of children.
Willett and Singer worry that this method for measuring school and student performance reflects not how efficiently individual students learn, but
what different groups of children know at a particular moment in time.
In the new paper, McClelland and her co-authors reviewed the theory and science behind a number of social emotional learning interventions in early childhood and found that while several such interventions hold promise, more research is needed to understand variations in results
among different groups of children, including why some children appear to benefit more than others and whether the programs are cost effective.
As Miratrix explains, they were interested in seeing how
these different groups of children performed.
