    I don't have Siri, but pretty much everything I've read about it indicates that it isn't reliable. Voice to text that works is going to beat speech recognition that doesn't work reliably any day of the week.

    $60 a month is a lot of money, perhaps your independently wealthy, but for most people that is a lot of money that they could be using for other things. That's just about more than the cost of a voice plan around here.

    That implies that we don't know how to teach most students, which really does requires some evidence to support. I've yet to see a set of tests that are used for that purpose that have any real world validity. Shanghai just beat out every other set of students in the world, they did it by doing homework 7 days a week and being in school 12 hours on weekdays. Yes, they outscored everybody else, but it isn't just a matter of the raw scores, there's opportunity costs that come from spending that much time in class and there's no compelling reason to believe that the success on that test will carry over into other areas of life. Students spend significantly less time learning than they did when I was a kid, and we spent significantly less time than my parents did. It's not that we did any less work, it's that we're more focused on learning how to take tests than they used to be.

    As for the students, the schools have always been way too easy for the brightest students and that problem goes back at least 400 years and probably even further. If that weren't the case you wouldn't see folks like Hobbes going to college so early, even now it's not unusual for students to start college at 15 around here. When the normal age of entrance is 18 minimum.

    More than that, there are better solutions, the boredom could be alleviated by spending more money on visual aids and developing engaging curriculum. I was bored out of my skull in classes as well, but it wasn't just a matter of the lack of difficulty, it was the lack of diversity in lesson planning. Going to class day in and day out and listening to lectures just isn't something that's particularly effective.

  3. Re:First: Fund Methods That Have Evidence They Wor on Grant To Allow Khan Academy To Expand, Build a Physical School · · Score: 1

    That's broadly true of most areas of education. For instance, language classes need to hit four domains with most lessons to be most effective. That is to say reading, writing, listening and speaking, the problem being that a site like the Khan Acadamy isn't going to be well suited to the writing and speaking components, and be very heavy on the reading and listening components. One can still learn like that, but it's a much slower process.

    To an extent that applies to other subjects as well, you'd be surprised how much you can learn doing problems, even if you've done one or two like it before, the results add up over time, but if you don't have somebody to check your work or show you how to do it, you're going to take a lot longer to learn it, assuming you do in the first place.

    Indeed, as a supplement, I think the Khan Academy is really useful. The way it's laid out really supports its use as a supplemental resource. But, it's not set up in a way that's going to replace anybody's classroom. Taking a quick look at the algebra section, there's a few lessons, but there isn't any obvious ordering to it, aside from not doing the part 2 lessons before the part 1 ones.

    I would personally have to spend a substantial amount of time going through the lessons to decide the order and combination if I was going to use the materials exclusively to teach with. If I just need a lesson or two, it's not really that difficult, but the whole set up is not one that's going to be useful for somebody that doesn't know anything about how to create lesson plans.

    As far as retention goes, if you don't use it within about the first 20 minutes or so of encountering it, the likelihood of retaining the knowledge significantly drops for most people.

    It's $5m in grant money, that's really not that much, even for a small school. It might last them a couple years, but even that's doubtful, it costs a lot of money to start a school and I doubt that will hold them over for a year or two.

    It's more than that, the more connections you have between facts the more likely they are to be retained. A good class will involve more than just one modality of involvement by the students, and online classes of any sort really haven't managed to master that yet. Khan probably being even worse as there's no possibility of meeting off line and the tests being somewhat less vigorous than normal.

    I'm sure folks do learn from it, I just doubt very much that it's going to advance education much more than the encyclopedia did.

    That's not just going to happen if you're doing some research. Plus, European data protection laws don't apply to people that are living in the US. The EU can't enforce a judgment against a company with no presence in the EU, no matter how much they might want to. They would have to file suit in the US, where their data protection laws don't apply. Otherwise they would end up in a situation where they have a judgment that they can't collect on, assuming that the court rules they have jurisdiction in the first place.

    EBay doesn't have a reputation system. A reputation system requires that parties be able to add or subtract from the feedback based upon their views. There will be a few that don't match or are wrong, but over time the values will tend to reflect reality.

    With eBay, they don't let sellers leave negative feedback anymore and as a result the whole system is badly flawed and tends to just reward bad behavior by buyers.

    The story is unchanged, but the quality discs have all sorts of features, like they did with DVDs, but more extensive. The Princess Bride, for instance, had not just a remastered film, but a game and several rather long featurettes about how the film came to be.

    Except that most of the time when data is stored it's not been through the cloud, it's because a laptop has been lost, or there was a burglary. The cloud isn't really any substantial increase in risk, if you encrypt the data before it's stored on the cloud and go through the appropriate measures to ensure that the keys are protected from unauthorized use.

    Exactly, I can encrypt my data, but all that means is that if there is a match, which is definitely possible, I end up losing the entire volume rather than just a portion of it. Neither possibility is acceptable for a service of this type. The likelihood increases substantially when you start matching everybody's blocks to everybody elses blocks. It's unlikely that you'd have two such blocks within a particular customers data, but when you deal with all the customers' data...
