  • Slowness, Wisdom and Change
  • Tony Searl on 22 Jan 10
     
    Better we make the wise decision than the expedient one. Read the older educators... Read Ted Sizer and Deborah Meier and Herb Kohl... and feel the wisdom in their words. They write without hubris, but instead with an acknowledgment of their own flawed humanity. They write with an understand that they cannot be all things to all children, but with the knowledge that they must come as close as they can. I am far from religious, but I am reminded a lot these days of the serenity prayer: God grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference.

  • how to use data effectively -- not just their own data, but all the data that's available and relevant
  • Increased storage capacity demands increased sophistication in the analysis and use of that data
  • Once you've parsed the data, you can start thinking about the quality of your data
  • ...20 more annotations...
  • It's usually impossible to get "better" data, and you have no alternative but to work with the data at hand
  • The most meaningful definition I've heard: "big data" is when the size of the data itself becomes part of the problem
  • Precision has an allure, but in most data-driven applications outside of finance, that allure is deceptive. Most data analysis is comparative:
  • Storing data is only part of building a data platform, though. Data is only useful if you can do something with it, and enormous datasets present computational problems
  • Hadoop has been instrumental in enabling "agile" data analysis. In software development, "agile practices" are associated with faster product cycles, closer interaction between developers and consumers, and testing
  • Faster computations make it easier to test different assumptions, different datasets, and different algorithms
  • It's easer to consult with clients to figure out whether you're asking the right questions, and it's possible to pursue intriguing possibilities that you'd otherwise have to drop for lack of time.
  • Machine learning is another essential tool for the data scientist.
  • According to Mike Driscoll (@dataspora), statistics is the "grammar of data science." It is crucial to "making data speak coherently."
  • Data science isn't just about the existence of data, or making guesses about what that data might mean; it's about testing hypotheses and making sure that the conclusions you're drawing from the data are valid.
  • The problem with most data analysis algorithms is that they generate a set of numbers. To understand what the numbers mean, the stories they are really telling, you need to generate a graph
  • Visualization is crucial to each stage of the data scientist
  • Visualization is also frequently the first step in analysis
  • Casey Reas' and Ben Fry's Processing is the state of the art, particularly if you need to create animations that show how things change over time
  • Making data tell its story isn't just a matter of presenting results; it involves making connections, then going back to other data sources to verify them.
  • Physicists have a strong mathematical background, computing skills, and come from a discipline in which survival depends on getting the most from the data. They have to think about the big picture, the big problem. When you've just spent a lot of grant money generating data, you can't just throw the data out if it isn't as clean as you'd like. You have to make it tell its story. You need some creativity for when the story the data is telling isn't what you think it's telling.
  • It was an agile, flexible process that built toward its goal incrementally, rather than tackling a huge mountain of data all at once.
  • we're entering the era of products that are built on data.
  • We don't yet know what those products are, but we do know that the winners will be the people, and the companies, that find those products.
  • They can think outside the box to come up with new ways to view the problem, or to work with very broadly defined problems: "here's a lot of data, what can you make from it?"

  • SNAPP is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies.
  • Discussion forum activity is a good indicator of student interactions and is systemically captured by most LMS. SNAPP uses information on who posted and replied to whom, and what major discussions were about, and how expansive they were, to analyse the interactions of a forum and display it in a Social Network Diagram. The following figures illustrate how SNAPP re-interprets discussion forum postings into a network diagram.
  • What can a network diagram tell me? A network diagram is a visual depiction of all interactions occurring among students and staff. This information provides rapid identification of the levels of engagement and network density emerging from any implemented online learning activities. Social network visualisations provide a snapshot of who is communicating with whom and to what level. A network diagram of your students’ discussions online can:

  • Taking a test is not just a passive mechanism for assessing how much people know, according to new research. It actually helps people learn, and it works better than a number of other studying techniques.
  • students who read a passage, then took a test asking them to recall what they had read, retained about 50 percent more of the information a week later than students who used two other methods.
  • What we recall becomes more recallable in the future. In a sense you are practicing what you are going to need to do later

  • “I believe in innovation and that the way you get innovation is you fund research and you learn the basic facts."

      agree with that
  • next to nothing is spent on education research. "That's partly because of the problem of who would do it. Who thinks of it as their business? The 50 states don't think of it that way, and schools of education are not about research.

      just how Sydney Uni/Sydney Teacher's College informed my practice 30 years ago. Bathwater principle envoked. Why did it ever stop?

    Gates says his foundation is currently focusing on using private funds to inform and redirect how public education dollars are spent, specifically in the form of research.- my note "agreeable findings" concern as "research" can then rapidly influence policy.

  • we have to see the teachers in front of us.
  • I want to know who broke this teacher. I want to know why. I want to understand… and I want to help her see that it doesn't have to be that way… that hurt doesn't have to be permanent… that the kids are still there, waiting for her.
  • And that's not going to happen with the current trends in educational policy. In fact, the current movement will engender less empathy, not more.
