  1. Education data systems rely on teacher input on All Your Child's Data Are Belong To InBloom · · Score: 5, Interesting

    My county's school system uses an on-line system to involve parent's in the education process. Student attendance, assignment status, and grades are posted in the system; parents access the system to monitor how their children are doing, and can theoretically use the information to apply virtually real-time corrective action. Everyone's involved, so this is good, right?

    Unfortunately, we have discovered that not all of the teachers are good at getting data in. After several episodes of us correcting our child and then finding out that the data in the system was inaccurate (assignments turned in were not credited, leading to fails and missing assignments) we have very mixed feelings about using the system.

    On the one hand, having access to see that assignments are/aren't being turned in, and seeing grades even if the work doesn't make it back home, is good. On the other hand, when the quality of the data is bad, it becomes virtually useless for the purpose of involving the parent in the education process. We can never be sure that a missing assignment is really missing; often a week or more later the system will be updated to show that the assignment was turned in after all.

    In one extreme example, a report that was delivered in class and turned in at the end of the presentation was given a grade of zero for never being turned in, and it was an end of the year project report worth a significant portion of the grade. When we went to bat for our kid, the teacher eventually admitted that the report had been delivered in class but didn't know where the hardcopy went. It was too late to turn in a copy of the hardcopy, so in the end that grade was just removed from my child's average. Since she had an "A" anyway, it wasn't harmful, but could have been if she had a lower grade and the report would have brought it up.

    My point with all this is that these systems all sound great, but unless an incredible effort is put in the data quality may not be sufficient for the purpose of the system. Its worse to have a system with low quality data that can't be relied upon than it would be to not have the system at all, in my opinion. Depending on how many people are relying on the system and in what ways, it could be extremely problematic. The traditional "end of marking period only" grading system has lots of play where teachers can make adjustments. This is bad if they abuse the power, but is good if they simply correct for lapses. A more realtime scoring system may not have the same flexibility yet may be being used in a more direct feedback manner. Data quality issues will be harder to correct, yet the dependency on the data correctness will be higher.

  2. Re:Teaching coding first on Who Will Teach U.S. Kids To Code? Rupert Murdoch · · Score: 1

    I think that learning the basic aspects of programming, and some coding, provides an understanding of the formal expression of algorithms (as well as the possibilities and limitations of expressing one's self in a manner suitable for machine-interpretation) that is very useful when learning the more theoretical aspects of computer science.

    There may be some value in trying to teach concepts apart from the formal expression of those concepts; we could try it out with integral and differential calculus as well - we could try teaching the concepts of calculus to people without the formalism of an algebra.

    Absent a tested educational theory showing the value of teaching the concepts before the formal expression, it might be ok to follow the traditional path of achieving some formal language capability in order to bolster the teaching of the concepts.

    My disclaimer: I have a very traditional "Computer and Information Science" bachelors (formal language theory, complexity, machine architecture, etc.) which I found relatively easy to get in part because I had learned BASIC, Fortran, and COBOL programming in a vocational high school. My peers seemed to struggle a lot more, even in the relatively simple Pascal programming, assembly language programming, and data structures classes. Those that survived freshman/sophomore years seemed to do ok in the more theoretical aspects, however.

  3. Re:Terrible article on Beware the Internet · · Score: 1

    I have often wondered how much critical infrastructure is connected to/through the Internet. Back in the late 1990s I was involved in security assessments of petrochemical firms. I was astounded to find out that they were beginning to attach their SCADA networks to their internal enterprise data networks, which were in turn attached to the Internet. Moving forward a couple of years, lots of companies started using Internet-based VPNs to eliminate leased-line connectivity to remote offices, because it was cheaper. The cost savings outweighed the potential availability concerns at the time. In retrospect, that tradeoff has turned out a lot better than I thought it would at the time - Internet services tend to be fairly stable. The security angle is harder to figure. It is possible to secure things quite well, but such security requires money, competent design, and a constant attention to detail over years of *nothing happening* (except for ankle-biter attacks that are thwarted easily and may very well bring about a false sense of security). By way of example, the vulnerabilities in commercial aviation security that allowed 9/11 to happen were obvious upon reflection, but weren't spotted prior even though lots of money was spent and lives were at stake.

    Projecting these trends forward in time, I don't have trouble believing that there might be substantial interconnections between the Internet and critical infrastructure, and that not all of it is protected well. The idea that "disconnecting critical infrastructure from the Internet is the best way to protect it" seems simple, but economic drivers appear to hold sway and keep this from happening. The US government has a "cyber command" center at Ft. Meade specifically tasked with "critical infrastructure protection." It seems absurd for the government to drop big $$ into CIP when the simple answer is to just disconnect it from the Internet.

    I don't know whether there is a lot of critical infrastructure connected to the Internet, but if there is then I believe there are big economic incentives that outweigh the security disadvantages, at least in the minds of the people paying the bills. It isn't that the Internet is required for them to function, it is that it is economically advantageous to the people who control them to use the Internet instead of some other data service. So the exposure can be real yet not very amenable to correction since it involves exactly the kind of very low probability/high impact risk that humans, especially those concerned about expenses, have trouble dealing with well.

    I am not a pilot nor am I trained in aviation. My impression of the Air France disaster was that it was caused, in part, by an incorrect mental model of the situation in the mind(s) of the pilot(s). The pilot at the controls was making control inputs that didn't make sense for the situation, but he wasn't an idiot, so he must have not understood the situation. It didn't seem to help matters that the aircraft systems quit warning about a stall when the systems could not make sense of the sensor inputs, then resumed warning about a stall when the sensor inputs started making sense, possibly causing the pilot to think he had just initiated a stall (again) instead of beginning the process of recovering. It seemed like the senior pilot finally figured it out at the end (too late).

    I think I good approach would be to identify and present options to management for reducing that 8% down to 4%. Done honestly, recommending eliminating waste and increasing productivity of higher-priority services, and recommending the elimination of lower priority services altogether, this will give management an understanding of the cost to the organization of reducing the IT budget as requested.

    Approaches that involve trying to tell management that they are wrong, or stupid, or don't know what they are doing aren't likely to go over well with management unless you can identify some factor that management isn't considering (yet). Unless one is in management, its not one's job to make those decisions. It is one's job to provide information to management so that they can make informed decisions.

  6. Informed consent would be good on Ask Slashdot: Explaining Cloud Privacy Risks To K-12 Teachers? · · Score: 1

    The concern is "My immediate issue isn't so much about the use of the cloud services now, but the ethics over lack of disclosure in the parental consent process. Does anyone have ideas about defining the parameters of 'informed consent' where we inform of risks without bringing about paranoia? (Google Apps is just an example here, I think it applies to many cloud services.)"

    I think transparency is a good thing. If the school system provides information to the parents about what kind of information will and may be stored "in the cloud," along with a summary of whatever legal obligations the school system has placed upon the provider with whom they are contracting (or whatever legal promises the provider is making if not under contract), then the goal of transparency will be met. If the school system balks at providing that kind of information, then I would question the appropriateness of the school system's action. The school system's fear of what parents might think if they knew what was being stored in the cloud is not a good reason for the school system to avoid this disclosure. My $0.02.

    If the school has based part or all of their educational approach on the use of a particular cloud service for which parental consent is required but for which parental consent might be withheld, then the school system has a lot at stake in getting consent. That might be clouding their judgement. If so, there are deeper problems here than just the need for full disclosure. If the law requires parental consent, it is probably for a good reason. The school system shouldn't be allowed to subvert the requirement for parental consent by creating a situation in which a lack of consent results in a major problem for the educational approach. If the school system doesn't like that, the school system should get the parental consent law changed first. One of the aspects of the USA constitutional system is preventing the tyranny of the masses (in this case the possibility that a parent who objects to a school system practice which they disagree being made to give their consent to it by limiting disclosure because the school assumed in its plans that everyone would go along) and even if the OP is not in the US, the principle is still valid (IMO).

    The whole idea of a "digital footprint," corporate data mining, etc. is (I believe) a very valid concern and one that the parents should be allowed to control on behalf of their kids until such point as their kids are on their own. Personally, I think that at a minimum the same kinds of protections that HIPPA requires for health information should apply to information stored about minors. If data mining is going to happen, it should be done in a fashion that eliminate the possibility that specific information will be tied to specific individuals.

    Many years ago, when I was a computer science student (1980 or so), I thought a lot about predictions of a loss of privacy due to computerization of record keeping. I postulated an argument similar to yours - perhaps the computerization of all records is merely returning our overgrown towns and cities to the previous status quo, when everyone knew (mostly) everything about everyone else. Then I realized that there was a big difference. In the small town, everyone knows everything about everyone else; its reciprocal. But with widespread electronic record keeping, there will inevitably be a state where a few people (relatively) know just about everything about most people, yet the bulk of the people will know next to nothing about those few. That is the inequity. I think its even more troubling that the mining of these massive quantities of data may be used to justify discrimination and further scrutiny against people who would otherwise not be suspected of evil thoughts. Who will watch the watchers, indeed? If the watchers are all hidden behind secrecy laws, and even the watchers interpretations of laws are secret, what is the basis for the two-way communication of knowledge that is found in a "small town"? How can we agree to be governed by laws that don't mean what we believe them to mean on their face, but which have secret meanings that are used to carry out activities many would believe illegal if those secret interpretations were made public?

    I read once that middle-age is always 10 years older than you are now. I'm not sure that is true forever, especially since now that I'm knocking on 50 its hard to convince myself that middle age is 60 :-)

    My calculation for "middle-aged" is certainly different than yours, however.

    The point of all this is that just like being out at night, in the snow and cold, you have to keep moving forward. Whether its developing skills that enable you to do work for which others will pay you so that you can live, or preparing for retirement, or whatever, you have to keep moving forward. If you lay down, you die (I mean this figuratively, but for some people it becomes literally true).

I think that from their point of view they are discouraging such actions or even "getting even" with the people who take such actions, and as long as they do so legally (i.e., making charges which might not stick but for which charging they will not themselves be held to have violated the law), they haven't done anything wrong even though they know the charges will be thrown out (as these were).

    My own point of view is that the ability for citizens to directly and provably monitor police activity has been too long in coming. I have heard of too many incidences where when Joe Public runs afoul of what a police officer wants the law to be, Joe Public loses. I have always believed that the US is a nation of laws, not men. At the lowest level this means that the same laws apply to all citizens, regardless of whether they are a police officer or not. However, courts tend to favor the testimony of a police officer over another citizen, and only in the most egregious circumstances seem to even begin to hold police officers to the same standards that other citizens are held. I know that a "dirtbag" will say anything in court to escape conviction, and so I understand (even if I don't like) the tendency to believe the police officer and not another citizen, all things being equal. However, A/V evidence has the benefit of being far more objective than any eye witness, especially those personally involved.

    Regardless of wiretapping laws, concern over being exposed, etc. I think that the right of citizens to monitor the actions of other citizens placed in positions of power should be upheld in order to prevent the abuse of those positions of power.
