• Charter School Authorization And Growth

    If you ask a charter school supporter why charter schools tend to exhibit inconsistency in their measured test-based impact, there’s a good chance they’ll talk about authorizing. That is, they will tell you that the quality of authorization laws and practices -- the guidelines by which charters are granted, renewed and revoked -- drives much and perhaps even most of the variation in the performance of charters relative to comparable district schools, and that strengthening these laws is the key to improving performance.

    Accordingly, a recently-announced campaign by the National Association of Charter School Authorizers aims to step up the rate at which charter authorizers close “low-performing schools” and are more selective in allowing new schools to open. In addition, a recent CREDO study found (among other things) that charter middle and high schools’ performance during their first few years is more predictive of future performance than many people may have thought, thus lending support to the idea of opening and closing schools as an improvement strategy.

    Below are a few quick points about the authorization issue, which lead up to a question about the relationship between selectivity and charter sector growth.

  • Relationship Counseling

    A correlation between two variables measures the strength of the linear relationship between them. Put simply, two variables are positively correlated to the extent that individuals with relatively high or low values on one measure tend to have relatively high or low values on the other, and negatively correlated to the extent that high values on one measure are associated with low values on the other.

    Correlations are used frequently in the debate about teacher evaluations. For example, researchers might assess the relationship between classroom observations and value-added measures, which is one of the simpler ways to gather information about the “validity” of one or the other – i.e., whether it is telling us what we want to know. In this case, if teachers with higher observation scores also tend to get higher value-added scores, this might be interpreted as a sign that both are capturing, at least to some extent, "true" teacher performance.

    Yet there seems to be a tendency among some advocates and policy makers to get a little overeager when interpreting correlations.

  • Unreliable Sources: Education Revenue During The Recession

    For the better part of the past century, U.S. public education revenue has come predominantly from state and local sources, with the federal government contributing only a relatively small share. For most of this time, local revenue (primarily property taxes) comprised the largest proportion, but this began to shift gradually during the 1970s, to the point where state funds constituted a slightly larger share of overall revenue.

    As you can see in the simple graph below, which uses data from the U.S. Census Bureau, this situation persisted throughout the 1990s and most of the 2000s. During this period, states provided roughly 50 percent of total revenue, localities about 45 percent, and the federal government approximately 5-8 percent. Needless to say, these overall proportions varied quite a bit by state. Vermont represents one of the most extreme examples, where, as a result of a 1997 State Supreme Court decision, education funding comes almost entirely from the state. Conversely, since Hawaii’s education system consists of a single statewide district, revenue on paper is dominated by state sources (though, in Hawaii's case, you might view the state and local levels as the same).

    That said, the period of 2008 to 2010 was a time of pretty sharp volatility in the overall proportions contributed by each level of government.

El-Shazli. Currently a visiting professor at Georgetown University’s Center for Democracy and Civil Society, Prof. El-Shazli  has 25 years of international experience in political and economic development, including democracy promotion programs and  support  for independent trade unions. She has worked with trade unions, political parties, and leaders throughout the Middle East and North Africa (MENA). The views expressed here are her own.

    Egypt has become a land of stark, astounding contradictions. There is so little stability that political pundits cannot predict or even explain what is happening in the political sphere or society. As it is in politics, it is in daily life. Some examples:

    Driving in Cairo has become the art of the detour. Demonstrations and protests can materialize any time of day and anywhere. If a protesting mass of humanity does not impede your way, then one of the new cement block walls will. These walls are erected by the government across major streets to contain demonstrations. Surely the time is right for some inventor to launch a new app -- “Avoid Protests - Egypt” -- to guide drivers and protesters alike.

    Times are not tough for everyone. In the affluent areas of Cairo, youngsters still sport the latest fashions, shoppers carry home their purchases, and restaurants brim with high class clientele. New restaurants are opening and one even sells fancy “cupcakes," the craze imported from the US. One would hardly believe that, for the average Egyptian, the country is indeed sinking into a financial abyss. But that is what's happening.

  • The FCAT Writing, On The Wall

    The annual release of state testing data makes the news in every state, but Florida is one of those places where it is to some degree a national story.*

    Well, it’s getting to be that time of year again. Last week, the state released its writing exam (FCAT 2.0 Writing) results for 2013 (as well as the math and reading results for third graders only).  The Florida Department of Education (FLDOE) press release noted: “With significant gains in writing scores, Florida’s teachers and students continue to show that higher expectations and support at home and in the classroom enable every child to succeed.” This interpretation of the data was generally repeated without scrutiny in the press coverage of the results.

    Putting aside the fact that the press release incorrectly calls the year-to-year changes “gains” (they are actually comparisons of two different groups of students; see here), the FLDOE's presentation of the FCAT Writing results, though common, is, at best, incomplete and, at worst, misleading. Moreover, the important issues in this case are applicable in all states, and unusually easy to illustrate using the simple data released to the public.

  • How Are Students Assigned To Teachers?

    Education researchers have paid a lot of attention to the sorting of teachers across schools. For example, it is well known that schools serving more low-income students tend to employ teachers who are, on average, less qualified (in terms of experience, degree, certification, etc.; also see here).

    Far less well-researched, however, is the issue of sorting within schools – for example, whether teachers with certain characteristics are assigned to classes with different students than their colleagues in the same school. In addition to the obvious fact that which teachers are in front of which students every day is important, this question bears on a few major issues in education policy today. For example, there is evidence that teacher turnover is influenced by the characteristics of the students teachers teach, which means that classroom assignments might either exacerbate or mitigate mobility and attrition. In addition, teacher productivity measures such as value-added may be affected by the sorting of students into classes based on characteristics for which the models do not account, and a better understanding of the teacher/student matching process could help inform this issue.

    A recent article, which was published in the journal Sociology of Education, sheds light on these topics with a very interesting look at the distribution of students across teachers' classrooms in Miami-Dade between 2003-04 and 2010-11. The authors’ primary question is: Are certain characteristics, most notably race/ethnicity, gender, experience, or pre-service qualifications (e.g., SAT scores), associated with assignment to higher or lower-scoring students among teachers in the same school, grade, and year?

  • On Teacher Evaluation: Slow Down And Get It Right

    ** Reprinted here in the Washington Post

    The following is written by Morgan S. Polikoff and Matthew Di Carlo. Morgan is Assistant Professor in the Rossier School of Education at the University of Southern California.

    One of the primary policy levers now being employed in states and districts nationwide is teacher evaluation reform. Well-designed evaluations, which should include measures that capture both teacher practice and student learning, have great potential to inform and improve the performance of teachers and, thus, students. Furthermore, most everyone agrees that the previous systems were largely pro forma, failed to provide useful feedback, and needed replacement.

    The attitude among many policymakers and advocates is that we must implement these systems and begin using them rapidly for decisions about teachers, while design flaws can be fixed later. Such urgency is undoubtedly influenced by the history of slow, incremental progress in education policy. However, we believe this attitude to be imprudent.

  • Proposed National Civics Framework Shows Great Promise

    Our guest author today is Stephen Lazar, a founding teacher at Harvest Collegiate High School in New York City, where he teaches Social Studies. A National Board certified teacher, he blogs at Outside the Cave. Stephen is also one of the organizers of Insightful Social Studies, a grass roots campaign of teachers to reform the newly proposed New York State Social Studies standards.

    A couple of months ago, I warned, “We cannot possibly continue to move solely in the direction of ‘college and career readiness’ in History & Social Studies education without ensuring that ‘civic’ readiness is valued equally." While our struggle continues in New York State, the Council of Chief State School Officers (CCSSO) took an extremely promising first step towards assuaging my fears with the release of The College, Career, and Civic Life (C3) Framework for Social Studies State Standards. This document was intended for a targeted review by certain groups last month. Copies, however, are not difficult to find by searching.

    Simply put, the proposed C3 Framework is brilliant. It is exactly what our nation needs to ensure civic life and participation is properly valued, and it is what the Social Studies teaching profession needs to ensure our discipline retains its unique and essential role within our education system. It is brilliant in its conception, its modesty and its usefulness as a document to inform policy and practice.

  • A Quick Look At "Best High School" Rankings

    ** Reprinted here in the Washington Post

    Every year, a few major media outlets publish high school rankings. Most recently, Newsweek (in partnership with The Daily Beast) issued its annual list of the “nation’s best high schools." Their general approach to this task seems quite defensible: To find the high schools that “best prepare students for college."

    The rankings are calculated using six measures: graduation rate (25 percent); college acceptance rate (25); AP/IB/AICE tests taken per student (25); average SAT/ACT score (10); average AP/IB/AICE score (10); and the percentage of students enrolled in at least one AP/IB/AICE course (5).

    Needless to say, even the most rigorous, sophisticated measures of school performance will be imperfect at best, and the methods behind these lists have been subject to endless scrutiny. However, let's take a quick look at three potentially problematic issues with the Newsweek rankings, how the results might be interpreted, and how the system compares with that published by U.S. News and World Report.

  • The Relationship Between Teacher Salaries And Teacher Salary Schedules

    The National Council on Teacher Quality (NCTQ) has released a brief report on teacher salary schedules since the recession.

    NCTQ looks at 41 of the 50 largest districts in the U.S. (i.e., all but nine responded to the survey). Between 2008-09 and 2011-12, four out of five of these districts froze pay at least once. As would be expected, districts did so in different ways – sometimes by freezing step increases (or awarding them without associated raises), sometimes via lower (or no) cost of living adjustments, etc. It’s compelling evidence that public school teachers, like most U.S. workers, have felt the pain from the recession. This is useful information (also check out NCTQ’s TR3 database, a terrific resource).

    There are, however, a couple of points worth mentioning about salary schedules, which may seem picky (or even obvious), but they do bear on the data presented in this report.
