This report presents the findings of an evaluation sponsored by the Institute of Education Sciences (IES) at the U.S. Department of Education (ED) and conducted by Mathematica Policy Research (Mathematica) that uses a regression discontinuity (RD) design to assess the potential benefits of offering SES in districts that have unmet need. Specifically, the study focuses on six school districts in which more  eligible  students applied for SES than could be served with available funds (i.e., oversubscribed districts), and which therefore allocated scarce SES spaces by giving priority to lower-achieving students among the eligible applicants.

Is educational innovation the way to close the achievement gap? A lot of smart people are hoping it will solve the problem. In the past few months I've been around a lot of innovations. I have watched the Khan Academy (and Sal Khan himself) in action, dug into 'blended learning,' Rocketship and KIPP, and looked at some Early College High School programs. I've been reading about new iPad applications and commercial ventures like Learning.com, and teachers have been writing me about how they are using blogs to encourage kids to write, and Twitter for professional development. In many schools kids are working in team to build robots, while other schools are using Skype to connect with students across the state or nation. I've even watched two jazz groups - one in Rhode Island, the other in Connecticut - practice together on Skype! 'Innovation' per se is not sufficient, of course. We need innovations that level the playing field and give all kids - regardless of their parents' income - the opportunity to excel.

"I have reviewed, albeit superficially, the test-based components of several states' school rating systems (e.g., OH, FL, NYC, LA, CO), with a particular focus on the degree to which they are actually measuring student performance (how highly students score), rather than school effectiveness per se (whether students are making progress). Both types of measures have a role to play in accountability systems, even if they are often confused or conflated, resulting in widespread misinterpretation of what the final ratings actually mean, and many state systems' failure to tailor interventions to the indicators being used. One aspect of these systems that I rarely discuss is the possibility that the ratings systems are an end in themselves."

Are teachers' impacts on students' test scores ("value-added") a good measure of their quality? This question has sparked debate largely because of disagreement about (1) whether value-added (VA) provides unbiased estimates of teachers' impacts on student achievement and (2) whether high-VA teachers improve students' long-term outcomes. We address these two issues by analyzing school district data from grades 3-8 for 2.5 million children linked to tax records on parent characteristics and adult outcomes. We find no evidence of bias in VA estimates using previously unobserved parent characteristics and a quasi-experimental research design based on changes in teaching staff. Students assigned to high-VA teachers are more likely to attend college, attend higher- ranked colleges, earn higher salaries, live in higher SES neighborhoods, and save more for retirement. They are also less likely to have children as teenagers. Teachers have large impacts in all grades from 4 to 8. On average, a one standard deviation improvment in teacher VA in a single grade raises earnings by about 1% at age 28. Replacing a teacher whose VA is in the bottom 5% with an average teacher would increase students' lifetime income by more than $250,000 for the average classroom in our sample. We conclude that good teachers create substantial economic value and that test score impacts are helpful in identifying such teachers.

"A while back, I argued that Florida's school grading system, due mostly to its choice of measures, does a poor job of gauging school performance per se. The short version is that the ratings are, to a degree unsurpassed by most other states' systems, driven by absolute performance measures (how highly students score), rather than growth (whether students make progress). Since more advantaged students tend to score more highly on tests when they enter the school system, schools are largely being judged not on the quality of instruction they provide, but rather on the characteristics of the students they serve."

"A systematic search of the research literature from 1996 through July 2008 identified more than a thousand empirical studies of online learning. Analysts screened these studies to find those that (a) contrasted an online to a face-to-face condition, (b) measured student learning outcomes, (c) used a rigorous research design, and (d) provided adequate information to calculate an effect size. As a result of this screening, 50 independent effects were identified that could be subjected to meta-analysis. The meta-analysis found that, on average, students in online learning conditions performed modestly better than those receiving face-to-face instruction. The difference between student outcomes for online and face-to-face classes-measured as the difference between treatment and control means, divided by the pooled standard deviation-was larger in those studies contrasting conditions that blended elements of online and face-to-face instruction with conditions taught entirely face-to-face. Analysts noted that these blended conditions often included additional learning time and instructional elements not received by students in control conditions. This finding suggests that the positive effects associated with blended learning should not be attributed to the media, per se. An unexpected finding was the small number of rigorous published studies contrasting online and face-to-face learning conditions for K-12 students. In light of this small corpus, caution is required in generalizing to the K-12 population because the results are derived for the most part from studies in other settings (e.g., medical training, higher education)."

I think it is safe to say that most educated people understand that student achievement scores have been, and continue to be, manipulated for political ends. I suspect the truth lies somewhere between genuine concern for improving public education and an insidious desire to destroy public education. On that issue, I will leave you to decide. I would, however, like to give you an insider's view of a state supported scheme to shift our tax dollars to private companies at the expense of our students.
