DOPA is Back

Before the elections, potential DOPA (Deleting Online Predators Act) legislation was the target of posts on many educational blogs (including Learning Aloud). Now, it appears that active consideration of DOPA legislation is back.

How could anyone object to measures intended to thwart potential online predators? It is the means and not the goal (see my previous comments) that generates objections – blocking commercial social networking sites including commercial blog sites. Blocking potentially useful activities represents a significant down side. Failure to confront the most serious problems gives the appearance of doing something while accomplishing little (unsupervised access to the Internet outside of the school results in what data appear to indicate are the most serious problems). This is an issue with a political slant – the appearance that one is “fighting” for our kids sounds good and it may not be obvious what is lost when blocking a hodge-podge of sites.

Ubuntu

Every once in a while, that geek part of my personality forces its way to the surface. The time has come to describe Ubuntu.

I use open source software on several servers I operate (this one for example) because I have access to bandwidth, but not a lot of money. My hardware consists of older Macs (the cast-offs from computer labs) and the Mac OS is built on a linux foundation (BSD). From time to time operating this type of server requires a basic understanding of linux. Such requirements in combination with reading several accounts of the work of Linus Torvalds created a personal interest. Working with linux commands was kind of a throw back to my first experiences working with computers. You enter text command rather than interact with the computer through objects and menus.

I first heard of Ubuntu when listening to podcasts (probably Leo Laport but I can’t remember for sure). It was described as a version of Linux that could be run from a CD on a variety of hardware. The cool thing about this is that it was possible to experiment without having to worry about messing up the operating system of the computer (which was always somewhat of a concern when I was working on one of my servers).

When I finally got around to looking for Ubuntu (the holiday break), I encountered Edubuntu. The edubuntu community is attempting to develop a host of educational applications around ubuntu. Again, experimenting is low risk and no cost. You pretty much download a collection of resources associated with a CPU (e.g., Intel x86) and then burn a CD. You boot your computer from this CD. A user interface has been developed so you will have no trouble launching a variety of open source productivity (e.g., OpenOffice), Internet (Firefox) and educational apps.

The vision here is to create low cost alternatives for education and the resources are intended to be installed (not run from a CD) or run in thin client mode (programs are loaded from a file server when run).

If you have heard about open source alternatives to popular productivity tools or linux and were curious, this is a reasonable way to explore a bit. I would suggest you create a CD even if you have a specific interest (say OpenOffice). Getting OpenOffice to run on the Mac is a little more complicated than just downloading the program (e.g., you need X11 installed first), but running from the edubuntu CD just works (I must admit I did not deal with the issue of how I would store files I might create).

Quest For Truth

One of the benefits of blogging is that it is possible to follow-up on previous posts. I suppose this is similar to a news program doing a kind of “where are they now” segment.

A year or so ago, I wrote an entry that described the Department of Education’s effort to do a better job of evaluating the effectiveness of instructional software. This post described a research program to be initiated in 2004-2005 to evaluate 16 commercial reading and mathematics programs available to K-12 schools. Mathematica Policy Research and SRI were awarded the grant providing the resources to finally conduct quality research. Conducting educational research in a way that avoids confoundings and methodological flaws is extremely difficult so I have been attempting to follow the success of this project.

I have been able to locate a brief update provided by Mathematica in mid 2004. This update promises:

During summer and fall 2005, the team will analyze the data and prepare a report to be submitted to Congress. Consideration is being given to adding another year of data collection with the same teachers and new students. These data would be gathered in 2005-2006.

I am unable to locate a report resulting from this research. Online searches generate plenty of descriptions and announcements by the companies involved, but I have been unable to locate study results. I would think the initial results described above should be available. If you are aware of published results, I would appreciate an email.

Disregard my request for information. My emails generated a reply:

I expect ED will release our report on findings within six weeks or
thereabouts. When it is released, it will be posted at the Institute of
Education Sciences web site and also at edtech.mathematica-mpr.com.

Cranky

I have been reading “Got Game” and one of the core ideas is that differences in generational experiences (e.g., widespread exposure to video games during childhood and adolescence) create differences in values, etc.

With this reading as a context, today I encounter the concept of age-appropriate search engines (age sensititive). cRANKy (cute huh) recommends itself as the search engine for 50+ year olds. Sites are selected by the editors of Eon and rated by viewers.

Get this – the top two searches – sex and brain builders. No way I could make stuff like this up. 😉

Used Grabe

UGenie is an online service for comparing costs on music, books, and games. There is a special section for textbooks allowing college students to compare costs on used books. If you are a college student, you may be able to find your institution and course.

Looks like used copies of Grabe and Grabe are available for $59 (low price). Pretty amazing that many companies already have used copies of our new book. I guess we should not be surprised. Our thanks to those of you who purchased an original version. 🙂

I agree with the statement of the problem – I am confused by the recommended solutions

Shortly before holiday break, I commented on the Dec. 18 issue of Time that considered “How to Build a Student for the 21st Century”. A major source within Time’s coverage was “Tough Choices or Tough Times” – The Report of the Commission of Skills of the American WorkForce (executive summary). I am guessing this report will generate a lot of interest among business leaders and politicians. I purchased the full report and have now read it. I agree with the statement of the problem and I think I understand the basics of the proposed plan of action. My reaction, possibly because I am a member of “the establishment” (translate older and a career educator), is that the plan is naive and based on too many untested assumptions. The plan tends to get vague just where I want details. Rather than launch into a long description, what follows is my interpretation of key points. I encourge those interested in educational policy to read the full report.

The book outlines a growing economic challenge to the US as a consequence of outsourcing – low end or routinized jobs to countries with a cheap labor force or to technology and an increasing number of high end jobs to skilled professionals from other countries who are willing to work for much lower salaries that their US counterparts. The analysis seems very similar to that provided in Friedman’s The World is Flat.

High wages and corporate growth will depend on continuing innovation. It seems our educational system is not producing enough graduates with the knowledge (translate math and science although other content areas are mentioned) and creativity to compete. This is a threat to the future standard of living of many individuals and the general economy of the country.

The solution:

Create an educational system that meets or exceeds the accomplishments of the competition.

a) Assume that students will be ready for college when they are 16 (as I understand the model) because this is what must be regarded as the standard set by “the competition.”

b) Create two levels of examinations (one for what is now the sophomore year and one for what is now the senior year). The first is intended to determine mastery of knowledge and skills roughly equivalent to what we now regard as the traditional high school education. Passing this exam would allow entry into community college or trade schools. Passing the exam would also allow continuation in an advance high school curriculum equivalent to AP coursework.

c) Create a more productive system to meet these expectations.

1) Hire teachers from the top 1/3 rather than the bottom 1/3 of college students.

2) Improve early childhood education

3) Commit more resources to disadvantaged students.

While this system will cost more money, the Commission argues that there is efficiency in doing the job right the first time (moving students on to postsecondary education more quickly, reducing grade repeaters, reducing need for remedial programs).

Proposals likely to be controversial:

a) create a different model for paying teachers that allows a higher entering salary and then increases more dependent on productivity (student performance) than years of service

b) greater authority at the state level – e.g., teachers employed by the state – salary schedule would allow encouragement to work in high need areas

c) performance based system like NCLB but with an emphasis on the progress of all students rather than number of students meeting minimum standards – parents free to move students, more competition among schools, greater freedom for entities to form schools and compete for students

While the economic challenges do seem real, the assumed responsibility of the educational system for economic productivity, the focus on presently available examinations as indicators of the productivity of teachers and schools, and the validity of international comparisons of student achievement have been contested.

For example:

William’s Spady’s Paradigm Trap challenges the assumed consequences of test-based accountability systems (in reference to NCLB).

Critics of the law also can point to frightening evidence about the effects on schools and students of mandated testing-and-accountability programs that had emerged before the law was officially enacted and has been borne out since. These include lower educator motivation and morale; the loss in droves of talented and creative educators who retire or leave the system; a severe narrowing of curriculum offerings;major increases in student stress, dysfunctional behavior, failure rates, and dropout rates; and the wholesale suppression of nontraditional educational approaches.

Some years ago, Berliner and Biddle wrote a book entitled “The Manufactured Crisis” that offered me some reassurance that the US K-12 student was not the international laggard that some politicians and business leaders had contended (an online summary of some key points if you are interested). The date of this analysis is an issue (mid-1990s),

I am sure the debate is just beginning.

Here is a follow-up to this post. I now see that Colorado is seriously considering pursuing the proposals of this commission.

Pew Report on Adolescent Use of Social Software

The Pew Internet and American Life has published findings from a new study (survey concluded in mid November) examining teen use of social networks.

  • 55% of adolescents who use the net are reported to have created online profiles (more females than males).
  • 2/3 of those with a profile limit access

Teens describe their interest in social networking sites as a way to stay in touch with friends.

The findings seem to indicate that users are at least aware of potential dangers (only 1% say they are unaware of who can view their profile).

Andy Carvin extracts more stats from this same source.
