Why Do So Many Workers Have Bad Jobs?

About one in five American workers today have jobs that offer low wages, poor benefits and few opportunities for advancement. But what can you do, right? After all, don’t we know that what’s good for business is often not good for people?

Not really, argues Zeynep Ton, an adjunct associate professor at the MIT Sloan School of Management, in this recent article. Although the conventional wisdom is that companies have no choice but to pay their employees poorly to remain competitive, Ton’s research suggests the opposite is true: When companies invest in their workforce, everybody wins.

Ton studied the practices of four highly regarded retailers – Mercadona*, QuikTrip, Trader Joe’s, and Costco – and found that “highly successful retail chains not only invest heavily in store employees but also have the lowest prices in their industries, solid financial performance, and better customer service than their competitors." Indeed, low wages are “not a cost-driven necessity but a choice." Her analysis suggest that one key to breaking the perceived trade-off is “a combination of investment in the workforce and operational practices that benefit employees, customers, and the company."

Thoughts On Using Value Added, And Picking A Model, To Assess Teacher Performance

Our guest author today is Dan Goldhaber, Director of the Center for Education Data & Research and a Research Professor in Interdisciplinary Arts and Sciences at the University of Washington Bothell.

Let me begin with a disclosure: I am an advocate of experimenting with using value added, where possible, as part of a more comprehensive system of teacher evaluation. The reasons are pretty simple (though articulated in more detail in a brief, which you can read here). The most important reason is that value-added information about teachers appears to be a better predictor of future success in the classroom than other measures we currently use. This is perhaps not surprising when it comes to test scores, certainly an important measure of what students are getting out of schools, but research also shows that value added predicts very long run outcomes, such as college going and labor market earnings. Shouldn’t we be using valuable information about likely future performance when making high-stakes personnel decisions? 

It almost goes without saying, but it’s still worth emphasizing, that it is impossible to avoid making high-stakes decisions. Policies that explicitly link evaluations to outcomes such as compensation and tenure are new, but even in the absence of such policies that are high-stakes for teachers, the stakes are high for students, because some of them are stuck with ineffective teachers when evaluation systems suggest, as is the case today, that nearly all teachers are effective.

Are There Low Performing Schools With High Performing Students?

I write often (probably too often) about the difference between measures of school performance and student performance, usually in the context of school rating systems. The basic idea is that schools cannot control the students they serve, and so absolute performance measures, such as proficiency rates, are telling you more about the students a school or district serves than how effective it is in improving outcomes (which is better-captured by growth-oriented indicators).

Recently, I was asked a simple question: Can a school with very high absolute performance levels ever actually be considered a “bad school?"

This is a good question.

Underlying Issues In The DC Test Score Controversy

In the Washington Post, Emma Brown reports on a behind the scenes decision about how to score last year’s new, more difficult tests in the District of Columbia Public Schools (DCPS) and the District's charter schools.

To make a long story short, the choice faced by the Office of the State Superintendent of Education, or OSSE, which oversees testing in the District, was about how to convert test scores into proficiency rates. The first option, put simply, was to convert them such that the proficiency bar was more “aligned” with the Common Core, thus resulting in lower aggregate proficiency rates in math, compared with last year’s (in other states, such as Kentucky and New York, rates declined markedly). The second option was to score the tests while "holding constant" the difficulty of the questions, in order to facilitate comparisons of aggregate rates with those from previous years.

OSSE chose the latter option (according to some, in a manner that was insufficiently transparent). The end result was a modest increase in proficiency rates (which DC officials absurdly called “historic”).

A Research-Based Case For Florida's Education Reforms

Advocates of the so-called “Florida Formula," a package of market-based reforms enacted throughout the 1990s and 2000s, some of which are now spreading rapidly in other states, traveled to Michigan this week to make their case to the state’s lawmakers, with particular emphasis on Florida's school grading system. In addition to arguments about accessibility and parental involvement, their empirical (i.e., test-based) evidence consisted largely of the standard, invalid claims that cross-sectional NAEP increases prove the reforms’ effectiveness, along with a bonus appearance of the argument that since Florida starting grading schools, the grades have improved, even though this is largely (and demonstrably) a result of changes in the formula.

As mentioned in a previous post, I continue to be perplexed at advocates’ insistence on using this "evidence," even though there is a decent amount of actual rigorous policy research available, much of it positive.

So, I thought it would be fun, though slightly strange, for me to try on my market-based reformer cap, and see what it would look like if this kind of testimony about the Florida reforms was actually research-based (at least the test-based evidence). Here’s a very rough outline of what I came up with:

Selection Versus Program Effects In Teacher Prep Value-Added

There is currently a push to evaluate teacher preparation programs based in part on the value-added of their graduates. Predictably, this is a highly controversial issue, and the research supporting it is, to be charitable, still underdeveloped. At present, the evidence suggests that the differences in effectiveness between teachers trained by different prep programs may not be particularly large (see here, here, and here), though there may be exceptions (see this paper).

In the meantime, there’s an interesting little conflict underlying the debate about measuring preparation programs’ effectiveness, one that’s worth pointing out. For the purposes of this discussion, let’s put aside the very important issue of whether the models are able to account fully for where teaching candidates end up working (i.e., bias in the estimates based on school assignments/preferences), as well as (valid) concerns about judging teachers and preparation programs based solely on testing outcomes. All that aside, any assessment of preparation programs using the test-based effectiveness of their graduates is picking up on two separate factors: How well they prepare their candidates; and who applies to their programs in the first place.

In other words, programs that attract and enroll highly talented candidates might look good even if they don’t do a particularly good job preparing teachers for their eventual assignments. But does that really matter?

The Promise Of The Common Core

In recent months, the Common Core has come under increasing criticism from a number of different quarters.

An op-ed in the New York Times’ Week in Review is emblematic of the best of this disapproving sentiment. Yet even it mixes together fundamental misconceptions about the entire Common Core project with legitimate issues of inadequate preparation for teachers and students and poor implementation by state education departments and districts. The Common Core is described as a “radical curriculum” that was introduced with “hardly any public discussion." We are told that it is a “one size fits all” approach, built upon a standardized script that teachers must use for instruction. Finally, it is suggested that the Common Core is a “game that has been so prearranged that many, if not most, of the players will fail."

This is the Common Core seen through the prism of a fun house mirror. In truth, the Common Core is neither “radical” nor a “curriculum," but a set of grade level performance standards for student achievement in the core academic disciplines of English Language Arts and Mathematics.* Indeed, one of the more telling criticisms of the implementation of the Common Core is that in all too many states, districts and schools, these standards have not been developed into curricula which teachers could readily use in their classrooms.

A Path To Diversifying The Teaching Workforce

Our guest author today is Jose Vilson, a math educator, writer, and activist in a New York City public school. You can find more of his writing at http://thejosevilson.com and his book, This Is Not A Test, will be released in the spring of 2014.

Travis Bristol’s article on bringing more black men to the classroom has sparked a plethora of conversation around the roles of educators in our school system. If we look at the national educational landscape, educators are still treated with admiration, but our government has yet to see fit to create conditions in schools that promote truly effective teaching and learning. In fact, successful teaching in otherwise struggling environments happens in spite and not because of the policies of our current school systems.

Even as superintendents see fit to close schools that house large populations of teachers and students of color, we must observe the roles that educators of color play in their schools, whether they consider themselves “loners” or “groupers," as Bristol describes in the aforementioned article. When the Brown vs. Board of Education decision came down in 1954, districts across the nation were determined to keep as many white educators employed as possible. While integration plays a role in assuring equitable conditions for all children and exposes them to other peoples, segregation’s silver lining was that Black educators taught Black children Black history. Racial identification plays a role in self-confidence, and having immediate role models for our children of color matters for achievement to this day.

Egyptians Who Protest Worker Rights Abuses Are Labeled “Terrorists”

Our guest author today is Heba F. El-Shazli.  She has 25 years of experience in the promotion of democracy, independent trade unions, political and economic development. She has worked with institutions and leaders throughout the Middle East and North Africa (MENA) to challenge authoritarian regimes. Currently she is an adjunct professor at Georgetown University's Center for Democracy and Civil Society. The views expressed here are her own.

Amid the political and social chaos that reigns in Egypt today, a semblance of normality persists: People go to work; they buy food; they try to feed their families.  And, as in the past, Egyptians employers, with the active support of the Egyptian government, flagrantly violate fundamental workers rights. Workers are fired for trying to organize unions and they are not paid what they are owed, including legally mandated bonuses, profit-sharing and health care benefits or proper safety equipment.

There is a familiar political dimension to these events. Elements in the police and military are accusing workers who protest employer abuses of being “terrorists” -- which in today’s Egypt means members or supporters of the Muslim Brotherhood (MB). In a recent New York Times article, two Egyptian media sources claimed that the workers striking at the Suez Steel company were infiltrated by MB activists attempting to “destabilize” the country.

This is an accusation supported neither by the facts, nor the history of blue collar unions.

On Education Polls And Confirmation Bias

Our guest author today is Morgan Polikoff, Assistant Professor in the Rossier School of Education at the University of Southern California. 

A few weeks back, education policy wonks were hit with a set of opinion polls about education policy. The two most divergent of these polls were the Phi Delta Kappan/Gallup poll and the Associated Press/NORC poll.

This week a California poll conducted by Policy Analysis for California Education (PACE) and the USC Rossier School of Education (where I am an assistant professor) was released. The PACE/USC Rossier poll addresses many of the same issues as those from the PDK and AP, and I believe the three polls together can provide some valuable lessons about the education reform debate, the interpretation of poll results, and the state of popular opinion about key policy issues.

In general, the results as a whole indicate that parents and the public hold rather nuanced views on testing and evaluation.
