Larger Classes, No After-School, More School Choice

With mere correlations, one may find published data that may or may not support a relationship since in these cases, how the experiment is designed can yield conflicting results. What is particularly useful in education are studies where not a mere correlation is portrayed but also a logical underlying mechanism behind the correlation. This is important especially when considering the three items DeVos has considered: large classes, no after-school, and more school choice.
Let us begin with "school choice". First, there is no research out there that convincingly shows charter schools improve the delivery of basic education. And this is expected since there is really no mechanism that can explain how by just giving parents the choice can make schools better. Evidence from research is clear on this. Papers that often tout the success of charter schools miss the fact that these schools often select students who are already high-achieving.
It is ridiculous to suggest that larger classes benefit education. The fact that each learner inside the classroom is an individual means the larger the class, the greater the effort and time a teacher must give in order to tailor the instruction so that it reaches each and every student. What research tells us is that there is perhaps a compromise between size and cost, emphasizing that there is indeed a great risk if classes are large in size. Chingos and Whitehurst wrote about this years ago at Brookings in which they state: "The most influential and credible study of CSR is the Student Teacher Achievement Ratio, or STAR, study which was conducted in Tennessee during the late 1980s. In this study, students and teachers were randomly assigned to a small class, with an average of 15 students, or a regular class, with an average of 22 students. This large reduction in class size (7 students, or 32 percent) was found to increase student achievement by an amount equivalent to about 3 additional months of schooling four years later."
Lastly, no one can really doubt the relationship between learning time and learning outcomes. And good research likewise does not deny this especially for the specific program of 21st Century Community Learning Centers. Here are the improvements in math:

These are percentage increases, not just size effects. These are the effects seen if one considers only the scores in standardized tests, but after-school activities are designed not just to enhance performance in these tests. After-school activities have effects in other as equally if not more important aspects of basic education.
Education should never be viewed in terms of dollars. The price of failing in basic education is so high that no savings can justify.
