Today's Forecast: Cloud Computing In Education

It’s hard to tell whether cloud computing is "the next big thing" or just another buzz word, but, according to a recent survey of 5,300 organizations in 38 countries, change is already taking place: "the promises of reduced cost, improved performance and greater scalability" are driving interest in "moving to cloud."

But what does cloud computing mean to those of us who care about education, teaching and learning?

When an organization "goes cloud" it means that the organization no longer deals directly with many of its computing/IT needs – e.g., software, updates, storage etc. The key to understanding this model and its broader implications is to appreciate the transition it represents: from viewing computing as a product to viewing it as a service. Much like public utilities, IT resources are delivered to users through the internet, just like electricity is distributed to our homes through the power grid. Users pay according to their consumption level, and the service provider takes care of the rest – see here.

Evidently, by moving to the cloud, organizations (including schools and universities) can save on IT infrastructure and maintenance. Some have noted that the model could also bring about changes in the IT sector, perhaps require a different type of (and/or fewer) IT professionals. Second, cloud computing should also help increase accessibility to educational content and convenience. For example, if lessons and assignments are be posted and stored in the cloud (i.e., on the shared server), students can work from anywhere, collaborate/interact with their peers etc.

But what else is cloud computing?

The Deafening Silence Of Unstated Assumptions

Here’s a thought experiment. Let’s say we were magically granted the ability to perfectly design our public education system. In other words, we were somehow given the knowledge of the most effective policies and how to implement them, and we put everything in place. How quickly would schools improve? Where would we be after 20 years of having the best possible policies in place? What about after 50 years?

I suspect there is much disagreement here, and that answers would vary widely. But, since there is a tendency in education policy to shy away from even talking realistically about expectations, we may never really know. We sometimes operate as though we expect immediate gratification - quick gains, every single year. When schools or districts don't achieve gains, even over a short period of time, they are subject to being labeled as failures.

Without question, we need to set and maintain high expectations, and no school or district should ever cease trying to improve. Yet, in the context of serious policy discussions, the failure to even discuss expectations in a realistic manner hinders our ability to interpret and talk about evidence, as it often means that we have no productive standard by which to judge our progress or the effects of the policies we try.

A Republic At Risk

Hardly a week goes by when some newspaper or television network doesn’t feature where the U.S. ranks among the nations participating in the Programme for International Student Assessment (PISA). This test, administered to 15-year olds every three years, serves as a benchmark for “how we’re doing” in terms of education outcomes relative to our international competitors.

Because the results get so much attention, millions of Americans are aware that our students' average scores rank relatively low on all three tests (though, when you account for error margins, U.S. scores are actually roughly average). Such awareness has stirred up remarkable urgency to improve our education system – we are told this is a “Sputnik moment," and that the very future of our nation’s economy is at risk.

Yet, for all the attention we pay to our rankings on standardized tests, how many Americans are aware that, in terms of voter turnout (voters as a proportion of voting-age population) between 1945 and 2001, the U.S. ranked 138th out of the world’s 169 democracies? To whatever degree electoral participation is an indicator of the health of a republic, ours is a sick one indeed. And it’s about to get even sicker.

Education Advocacy Organizations: An Overview

Our guest author today is Ken Libby, a graduate student studying educational foundations, policy and practice at the University of Colorado at Boulder.

Education advocacy organizations (EAOs) come in a variety of shapes and sizes. Some focus on specific issues (e.g. human capital decisions, forms of school choice, class size) while others approach policy more broadly (e.g. changing policy environments, membership decisions). Proponents of these organizations claim they exist, at least in part, to provide a counterbalance to various other powerful interest groups.

In just the past few years, Stand for Children, Democrats for Education Reform (DFER), 50CAN, and StudentsFirst have emerged as well-organized, well-funded groups capable of influencing education policy. While these four groups support some of the same legislation - most notably teacher evaluations based in part on test scores and the expansion of school choice - each group has some distinct characteristics that are worth noting.

One thing’s for sure: The proliferation of EAOs, especially during the past five or six years, is playing a critical role in certain education policy decisions and discussions. They are not, contrary to some of the rhetoric, dominating powerhouses, but they aren’t paper tigers either.

Do Teachers Really Come From The "Bottom Third" Of College Graduates?

** Also posted here on 'Valerie Strauss' Answer Sheet' in the Washington Post

The conventional wisdom among many education commentators is that U.S. public school teachers “come from the bottom third” of their classes. Most recently, New York City Mayor Michael Bloomberg took this talking point a step further, and asserted at a press conference last week that teachers are drawn from the bottom 20 percent of graduates.

All of this is supposed to imply that the U.S. has a serious problem with the “quality” of applicants to the profession.

Despite the ubiquity of the “bottom third” and similar arguments (which are sometimes phrased as massive generalizations, with no reference to actual proportions), it’s unclear how many of those who offer them know what specifically they refer to (e.g., GPA, SAT/ACT, college rank, etc.). This is especially important since so many of these measurable characteristics are not associated with future test-based effectiveness in the classroom, while those that are are only modestly so.

Still, given how often it is used, as well as the fact that it is always useful to understand and examine the characteristics of the teacher labor supply, it’s worth taking a quick look at where the “bottom third” claim comes from and what it might or might not mean.

What Value-Added Research Does And Does Not Show

Has Teacher Quality Declined Over Time?

** Also posted here on "Valerie Strauss' Answer Sheet" in the Washington Post

One of the common assumptions lurking in the background of our education debates is that “quality” of the teaching workforce has declined a great deal over the past few decades (see here, here, here and here [slide 16]). There is a very plausible storyline supporting this assertion: Prior to the dramatic rise in female labor force participation since the 1960s, professional women were concentrated in a handful of female-dominated occupations, chief among them teaching. Since then, women’s options have changed, and many have moved into professions such as law and medicine instead of the classroom.

The result of this dynamic, so the story goes, is that the pool of candidates to the teaching profession has been “watered down." This in turn has generated a decline in the aggregate “quality” of U.S. teachers, and, it follows, a stagnation of student achievement growth. This portrayal is often used as a set-up for a preferred set of solutions – e.g., remaking teaching in the image of the other professions into which women are moving, largely by increasing risk and rewards.

Although the argument that “teacher quality” has declined substantially is sometimes taken for granted, its empirical backing is actually quite thin, and not as clear-cut as some might believe.

Smear Review

A few weeks ago, the National Education Policy Center (NEPC) issued a review of the research on virtual learning. Several proponents of online education issued responses that didn't offer much substance beyond pointing out NEPC’s funding sources. A similar reaction ensued after the release last year of the Gates Foundation's preliminary report on the Measures of Effective Teaching Project. There were plenty of substantive critiques, but many of the reactions amounted to knee-jerk dismissals of the report based on pre-existing attitudes toward the foundation's agenda.

More recently, we’ve even seen unbelievably puerile schemes in which political operatives actually pretend to represent legitimate organizations requesting consulting services. They record the phone calls, and post out-of-context snippets online to discredit the researchers.

Almost all of the people who partake in this behavior share at least one fundamental characteristic: They are unable to judge research for themselves, on its merits. They can’t tell the difference, so they default to attacking substantive work based on nothing more than the affiliations and/or viewpoints of the researchers.

The Categorical Imperative In New Teacher Evaluations

There is a push among many individuals and groups advocating new teacher evaluations to predetermine the number of outcome categories – e.g., highly effective, effective, developing, ineffective, etc. - that these new systems will include. For instance, a "statement of principles" signed by 25 education advocacy organizations recommends that the reauthorized ESEA law require “four or more levels of teacher performance." The New Teacher Project’s primary report on redesigning evaluations made the same suggestion.* For their part, many states have followed suit, mandating new systems with a minimum of 4-5 categories.

The rationale here is pretty simple on the surface: Those pushing for a minimum number of outcome categories believe that teacher performance must be adequately differentiated, a goal on which prior systems, most of which relied on dichotomous satisfactory/unsatisfactory schemes, fell short. In other words, the categories in new evaluation systems must reflect the variation in teacher performance, and that cannot be accomplished when there are only a couple of categories.

It’s certainly true that the number of categories matters – it is an implicit statement as to the system’s ability to tease out the “true” variation in teacher performance. The number of categories a teacher evaluation system employs should depend on how on how well it can differentiate teachers with a reasonable degree of accuracy. If a system is unable to pick up this “true” variation, then using several categories may end up doing more harm than good, because it will be providing faulty information. And, at this early stage, despite the appearance of certainty among some advocates, it remains unclear whether all new teacher evaluation systems should require four or more levels of “effectiveness."
