(the teeming void): This is Data? Arguing with Data Baby - 3 views

  • Making that call - defining what data is - is a powerful cultural gesture right now, because as I've argued before data as an idea or a figure is both highly charged and strangely abstract.
  • In other words data here is not gathered, measured, stored or transmitted - or not that we can see. It just is, and it seems to be inherent in the objects it refers to; Data Baby is "generating" data as easily as breathing.
  • This vision of material data is also frustrating because it has all the ingredients of a far more interesting idea: data is material, or at least it depends on material substrates, but the relationship between data and matter is just that, a relationship, not an identity. Data depends on stuff; always in it, and moving transmaterially through it, but it is precisely not stuff in itself.

  • Data does not just happen; it is created in specific and deliberate ways. It is generated by sensors, not babies; and those sensors are designed to measure specific parameters for specific reasons, at certain rates, with certain resolutions. Or more correctly: it is gathered by people, for specific reasons, with a certain view of the world in mind, a certain concept of what the problem or the subject is. The people use the sensors, to gather the data, to measure a certain chosen aspect of the world.
  • If we come to accept that data just is, it's too easy to forget that it reflects a specific set of contexts, contingencies and choices, and that crucially, these could be (and maybe should be) different. Accepting data shaped by someone else's choices is a tacit acceptance of their view of the world, their notion of what is interesting or important or valid. Data is not inherent or intrinsic in anything: it is constructed, and if we are going to work intelligently with data we must remember that it can always be constructed some other way.
  • We need real, broad-based, practical and critical data skills and literacies, an understanding of how to make data and do things with it.

  • Not everybody is happy when I say words have different meanings for each person that uses them. But it's hard to escape that conclusion when you actually look at language.
  • Geoffrey K. Pullum writes, "The people who think clarity involves lack of ambiguity, so we have to strive to eliminate all multiple meanings and should never let a word develop a new sense... they simply don't get it about how language works, do they?" A good lesson for the Semantic Web people, no?
  •  
    As we continue to refine the rubric, this short post is a useful reminder of the challenge....and the limits. We struggle in part because the formal assessment experience of many of our partners is not wide or deep, which in turns increases the language challenges.

If the systems and processes of university teaching and learning practice do not encourage and enable everyday consideration of alignment, is it surprising that many academics don’t consider alignment?

  • Raban (2007) observes that the quality management systems of most universities employ procedures that are retrospective and weakly integrated with long term strategic planning. He continues to argue that the conventional quality management systems used by higher education are self-defeating as they undermine the commitment and motivation of academic staff through an apparent lack of trust, and divert resources away from the core activities of teaching and research (Raban, 2007, p. 78).

Postgraduate Wrath - Brainstorm - The Chronicle of Higher Education - 0 views

  • "So, what I want to know is, why are you wasting money on glossy fundraising brochures full of meaningless synonyms for the word 'Excellence'? And, why are you sending them to ME? Yes, I know that I got a master's degree at your fine institution, but that master's degree hasn't done jack ---- for me since I got it! I have been unemployed for the past TWO YEARS and I am now a professional resume-submitter, sending out dozens of resumes a month to employers, and the degree I received in your hallowed halls is at the TOP OF IT and it doesn't do a ----ing thing."
  • Who knows how smart and conscientious and skilled the graduate really is. He might falter in face-to-face interviews, or have an overly-thin resume. But that doesn't change the fact that the school in question admitted the student, put him through a public policy curriculum, and accredited him. If the writer is a klutz, then that, too, reflects upon the university that trained him.
  • Obviously, this student doesn't recall any non-vocational learning that happened, or doesn't respect it. He even terms the education he received "imaginary."

How Group Dynamics May Be Killing Innovation - Knowledge@Wharton - 5 views

  • Christian Terwiesch and Karl Ulrich argue that group dynamics are the enemy of businesses trying to develop one-of-a-kind new products, unique ways to save money or distinctive marketing strategies.
  • Terwiesch, Ulrich and co-author Karan Girotra, a professor of technology and operations management at INSEAD, found that a hybrid process -- in which people are given time to brainstorm on their own before discussing ideas with their peers -- resulted in more and better quality ideas than a purely team-oriented process.

      They use the term "team oriented process" but what they mean, I think, is a synchronous, face to face, brainstorming session.
  • Although several existing experimental studies criticize the team brainstorming process due to the interference of group dynamics, the Wharton researchers believe their work stands out due to a focus on the quality, in addition to the number, of ideas generated by the different processes -- in particular, the quality of the best idea.
  • ...8 more annotations...
  • "The evaluation part is critical. No matter which process we used, whether it was the [team] or hybrid model, they all did significantly worse than we hoped [in the evaluation stage]," Terwiesch says. "It's no good generating a great idea if you don't recognize the idea as great. It's like me sitting here and saying I had the idea for Amazon. If I had the idea but didn't do anything about it, then it really doesn't matter that I had the idea."
  • He says an online system that creates a virtual "suggestion box" can accomplish the same goal as long as it is established to achieve a particular purpose.
  • Imposing structure doesn't replace or stifle the creativity of employees, Ulrich adds. In fact, the goal is to establish an idea generation process that helps to bring out the best in people. "We have found that, in the early phases of idea generation, providing very specific process guideposts for individuals [such as] 'Generate at least 10 ideas and submit them by Wednesday,' ensures that all members of a team contribute and that they devote sufficient creative energy to the problem."
  • The results of the experiment with the students showed that average quality of the ideas generated by the hybrid process were better than those that came from the team process by the equivalent of roughly 30 percentage points.
  • in about three times more ideas than the traditional method.
  • "We find huge differences in people's levels of creativity, and we just have to face it. We're not all good singers and we're not all good runners, so why should we expect that we all are good idea generators?
  • They found that ideas built around other ideas are not statistically better than any random suggestion.
  • "In innovation, variance is your friend. You want wacky stuff because you can afford to reject it if you don't like it. If you build on group norms, the group kills variance."

From Social Media to Social Strategy - Umair Haque - Harvard Business Review - 0 views

  • Choreography. Most organizations seek "high performance." Today, performance is no longer enough: excelling in yesterday's terms is excelling at the wrong things. This is downright self-destructive (just ask Wall Street). Today's radical innovators aren't merely mute performers, precisely executing the empty steps of a meaningless dance: they're more like choreographers. Choreographers define the steps of a better dance — they lay down better rules for interactions between supply and demand to take place.
    • Nils Peterson
       
      It strilkes me that this connects to OAI's Aof A work. We recognize learning outcomes can't forever improve, but through better assessment, we can hope the programs are ever more attentive and responsive to changing situations.

The Social Media Bubble - Umair Haque - Harvard Business Review - 1 views

  • Call it relationship inflation. Nominally, you have a lot more relationships — but in reality, few, if any, are actually valuable. Just as currency inflation debases money, so social inflation debases relationships.
    • Nils Peterson
       
      is this the case for dropping some of my social site accounts, eg FB, LinkedIn, etc?
  • On the demand side, relationship inflation creates beauty contest effects, where, just as every judge votes for the contestant they think the others will like the best, people transmit what they think others want. On the supply side, relationship inflation creates popularity contest effects, where people (and artists) strive for immediate, visceral attention-grabs — instead of making awesome stuff.
  • The social isn't about beauty contests and popularity contests. They're a distortion, a caricature of the real thing. It's about trust, connection, and community. That's what there's too little of in today's mediascape, despite all the hoopla surrounding social tools. The promise of the Internet wasn't merely to inflate relationships, without adding depth, resonance, and meaning. It was to fundamentally rewire people, communities, civil society, business, and the state — through thicker, stronger, more meaningful relationships. That's where the future of media lies.

Want Students to Take an Optional Test? Wave 25 Bucks at Them - Students - The Chronicl... - 0 views

  • cash, appears to be the single best approach for colleges trying to recruit students to volunteer for institutional assessments and other low-stakes tests with no bearing on their grades.
  • American Educational Research Association
  • A college's choice of which incentive to offer does not appear to have a significant effect on how students end up performing, but it can have a big impact on colleges' ability to round up enough students for the assessments, the study found.
  • ...6 more annotations...
  • "I cannot provide you with the magic bullet that will help you recruit your students and make sure they are performing to the maximum of their ability," Mr. Steedle acknowledged to his audience at the Denver Convention Center. But, he said, his study results make clear that some recruitment strategies are more effective than others, and also offer some notes of caution for those examining students' scores.
  • The study focused on the council's Collegiate Learning Assessment, or CLA, an open-ended test of critical thinking and writing skills which is annually administered by several hundred colleges. Most of the colleges that use the test try to recruit 100 freshmen and 100 seniors to take it, but doing so can be daunting, especially for colleges that administer it in the spring, right when the seniors are focused on wrapping up their work and graduating.
  • The incentives that spurred students the least were the opportunity to help their college as an institution assess student learning, the opportunity to compare themselves to other students, a promise they would be recognized in some college publication, and the opportunity to put participation in the test on their resume.
  • The incentives which students preferred appeared to have no significant bearing on their performance. Those who appeared most inspired by a chance to earn 25 dollars did not perform better on the CLA than those whose responses suggested they would leap at the chance to help out a professor.
  • What accounted for differences in test scores? Students' academic ability going into the test, as measured by characteristics such as their SAT scores, accounted for 34 percent of the variation in CLA scores among individual students. But motivation, independent of ability, accounted for 5 percent of the variation in test scores—a finding that, the paper says, suggests it is "sensible" for colleges to be concerned that students with low motivation are not posting scores that can allow valid comparisons with other students or valid assessments of their individual strengths and weaknesses.
  • A major limitation of the study was that Mr. Steedle had no way of knowing how the students who took the test were recruited. "If many of them were recruited using cash and prizes, it would not be surprising if these students reported cash and prizes as the most preferable incentives," his paper concedes.
  •  
    Since it is not clear if the incentive to participate in this study influenced the decision to participate, it remains similarly unclear if incentives to participate correlate with performance.

Why Don't Students Study Anymore? - Percolator - The Chronicle of Higher Education - 1 views

  • Here's what they found: In 1961, the average full-time college student spent 40 hours per week on academic work (that's time in class and studying). In 2003, it was 27 hours. The authors figure that 21st-century students spend an average of 10 hours fewer every week studying than their 1961 counterparts. Over the course of a four-year college career, that would add up to something like 1,500 fewer hours spent hitting the books.
  • the difference isn't caused by more people stretching out their college experience. Also, according to the authors, the difference can't be explained by the fact that more students have jobs or by the fact that the makeup of the student body has changed since the sixties. From the paper: "The large decline in academic time investment is an important pattern its own right, and one that motivates future research into underlying causes."In other words, we don't know why.

Colleges of education vary widely in their methods, and many alternative-certification programs require participants to take classes at colleges and universities, she pointed out. In some cases, students pursuing a traditional education degree and students in an alternative-certification program are in the same class.
