  • The basic idea was to make a radically editable learning environment in which students as well as faculty members could rearrange content, functionality, and navigation in the learning environment.

      Also, what fraction of _students_ will be excited by radical editability? Will a readiness assessment be needed?

    There are some work arounds cited in the bug tracker referenced but they include shutting off critically useful parts of Firebug. This is only an issue for people using recent Firefox and Firebug versions. I'm keeping a close eye on this one and will keep you all updated.

    A bad bug I've run into and am tracking. Basically if you combine the latest Firefox with recent Firebug you can get some rather nasty looking errors.

  • We are just two graduate students working on a shoestring budget.

    We agree with both President Obama and Senator Coburn that universal accessibility of such information is worthwhile goal. However, we believe this is only a first step. In a deep sense, our prior post is designed to serve as a demonstration project. We are just two graduate students working on a shoestring budget. With the resources of the federal government, however, it would certainly be possible to create a series of simple interfaces designed to broadly represent of large amounts of information. While these interfaces should rely upon the best available analytical methods, such methods could probably be built-in behind the scenes. At a minimum, government agencies should follow the suggestion of David G. Robinson and his co-authors who argue the federal government "should require that federal websites themselves use the same open systems for accessing the underlying data as they make available to the public at large."

Ranking Employees: Why Comparing Workers to Their Peers Can Often Backfire - Knowledge@... - 2 views

  • We live in a world full of benchmarks and rankings. Consumers use them to compare the latest gadgets. Parents and policy makers rely on them to assess schools and other public institutions,
  • "Many managers think that giving workers feedback about their performance relative to their peers inspires them to become more competitive -- to work harder to catch up, or excel even more. But in fact, the opposite happens," says Barankay, whose previous research and teaching has focused on personnel and labor economics. "Workers can become complacent and de-motivated. People who rank highly think, 'I am already number one, so why try harder?' And people who are far behind can become depressed about their work and give up."
  • mong the companies that use Mechanical Turk are Google, Yahoo and Zappos.com, the online shoe and clothing purveyor.
  • ...12 more annotations...
  • Nothing is more compelling than data from actual workplace settings, but getting it is usually very hard."
  • Instead, the job without the feedback attracted more workers -- 254, compared with 76 for the job with feedback.
  • "This indicates that when people are great and they know it, they tend to slack off. But when they're at the bottom, and are told they're doing terribly, they are de-motivated," says Barankay.
  • In the second stage of the experiment
  • The aim was to determine whether giving people feedback affected their desire to do more work, as well as the quantity and quality of their work.
  • Of the workers in the control group, 66% came back for more work, compared with 42% in the treatment group. The members of the treatment group who returned were also 22% less productive than the control group. This seems to dispel the notion that giving people feedback might encourage high-performing workers to work harder to excel, and inspire low-ranked workers to make more of an effort.
  • it seems that people would rather not know how they rank compared to others, even though when we surveyed these workers after the experiment, 74% said they wanted feedback about their rank."
  • top performers move on to new challenges and low performers have no viable options elsewhere.
  • feedback about rank is detrimental to performance,"
  • it is well documented that tournaments, where rankings are tied to prizes, bonuses and promotions, do inspire higher productivity and performance.
  • "In workplaces where rankings and relative performance is very transparent, even without the intervention of management ... it may be better to attach financial incentives to rankings, as interpersonal comparisons without prizes may lead to lower effort," Barankay suggests. "In those office environments where people may not be able to assess and compare the performance of others, it may not be useful to just post a ranking without attaching prizes."
  • "The key is to devote more time to thinking about whether to give feedback, and how each individual will respond to it. If, as the employer, you think a worker will respond positively to a ranking and feel inspired to work harder, then by all means do it. But it's imperative to think about it on an individual level."
  • Gary Brown on 23 Aug 10
     
    the conflation of feedback with ranking confounds this. What is not done and needs to be done is to compare the motivational impact of providing constructive feedback. Presumably the study uses ranking in a strictly comparative context as well, and we do not see the influence of feedback relative to an absolute scale. Still, much in this piece to ponder....

  • Does testing for statistical significance encourage or discourage thoughtful data analysis? Posted by Patricia Rogers on October 20th, 2010
  • Epidemiology, 9(3):333–337). which argues not only for thoughtful interpretation of findings, but for not reporting statistical significance at all.
  • We also would like to see the interpretation of a study based not on statistical significance, or lack of it, for one or more study variables, but rather on careful quantitative consideration of the data in light of competing explanations for the findings.
  • ...6 more annotations...
  • we prefer a researcher to consider whether the magnitude of an estimated effect could be readily explained by uncontrolled confounding or selection biases, rather than simply to offer the uninspired interpretation that the estimated effect is significant, as if neither chance nor bias could then account for the findings.
  • Many data analysts appear to remain oblivious to the qualitative nature of significance testing.
  • statistical significance is itself only a dichotomous indicator.
  • it cannot convey much useful information
  • Even worse, those two values often signal just the wrong interpretation. These misleading signals occur when a trivial effect is found to be ’significant’, as often happens in large studies, or when a strong relation is found ’nonsignificant’, as often happens in small studies.
  • Another useful paper on this issue is Kristin Sainani, (2010) “Misleading Comparisons: The Fallacy of Comparing Statistical Significance”Physical Medicine and Rehabilitation, Vol. 2 (June), 559-562 which discusses the need to look carefully at within-group differences as well as between-group differences, and at sub-group significance compared to interaction. She concludes: ‘Readers should have a particularly high index of suspicion for controlled studies that fail to report between-group comparisons, because these likely represent attempts to “spin” null results.”

shared by Gary Brown on 04 Dec 10 - No Cached
  • Principles of Genuine Evaluation When we set out to explore the notion of ‘Genuine Evaluation’, we identified 5 important aspects of it: VALUE-BASED -transparent and defensible values (criteria of merit and worth and standards of performance) EMPIRICAL – credible evidence about what has happened and what has caused this, USABLE – reported in such a way that it can be understood and used by those who can and should use it (which doesn’t necessarily mean it’s used or used well, of course) SINCERE – a commitment by those commissioning evaluation to respond to information about both success and failure (those doing evaluation can influence this but not control it) HUMBLE – acknowledges its limitations From now until the end of the year, we’re looking at each of these principles and collecting some of the highlights and lowlights  from 2010 (and previously).
  • Sincerity of evaluation is something that is often not talked about in evaluation reports, scholarly papers, or formal presentations, only discussed in the corridors and bars afterwards.  And yet it poses perhaps the greatest threat to the success of individual evaluations and to the whole enterprise of evaluation.

    In this landmark book, Scott Page redefines the way we understand ourselves in relation to one another.The Differenceis about how we think in groups--and how our collective wisdom exceeds the sum of its parts. Why can teams of people find better solutions than brilliant individuals working alone? And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique? The answers lie in diversity--not what we look like outside, but what we look like within, our distinct tools and abilities. The Differencereveals that progress and innovation may depend less on lone thinkers with enormous IQs than on diverse people working together and capitalizing on their individuality.

    We (Jayme Jacobson, Nils Peterson, and I) have been talking about this a lot lately. This article reminded me of another article in the Harvard Business Review by Lakhani and Jeppesen on crowdsourcing. They found that successful Innocentive solvers often worked in disciplines removed from the posted problem. "Radical innovations often happen at the intersections of disciplines…The more diverse the problem solving population, the more likely the problem will be solved."
