Laptop Computers and Teacher Change

Larry Cuban of the Stanford School of Education has published a short article titled 1:1 Laptops Transforming Classrooms: Yeah, Sure. In it, he repeats his argument from Oversold and Underused that classroom computing initiatives have not significantly transformed American classrooms.

In higher education, where students willingly choose to attend (in K-12 they are compelled by law to go to school), where students have already achieved 1:1 computing capacity, teachers and students mainly use these powerful machines to reinforce existing ways of teaching and learning.

I have no doubt about this. But I also recall from personal conversation with Larry that his argument says more about the profession of teaching in general than it does about laptop computers in particular. In his Stanford course The History of School Reform, Larry Cuban and David Tyack repeatedly drove the point home that American schooling has been incredibly resistant to change for at least a century. Different school reforms — bigger, smaller, more vocational, single-sex, magnet, gifted and talented — have hardly changed the typical American school.

What does Cuban’s perspective on schooling and technology imply for those of us working in one school? First, let us remember that Cuban recognizes the transformation of other activities by technology — communication and research especially. You could attempt to justify a computing initiative purely on these grounds. Next, let us ground technology initiatives within the space of other changes in schools. Just as a school might consider adopting a block schedule, starting school later in the day, or eliminating AP classes, school leaders should carefully consider the match between technology innovations and pedagogical theory, the time and energy required for teachers to change practice, and the amount of social capital one possesses within a group of professionals to make such a change.

Cuban estimates that only five percent of teachers considerably change their practice in the presence of new technologies. If we want to better that mark, then let us keep our heads screwed on straight when pushing for new technologies.

Better blog reading

I have thought a lot about blogging here the last couple of weeks, but I have not come across much worth blogging. I think that’s a good sign, as we have been consumed with the return of our fifth staff member from maternity leave, new job descriptions, server room power improvements, testing our new help desk system, and so on. My big open-source projects — two alumni web sites, gallery, Moodle, and custom scripts — have been stable lately after a period of intensive development. I have a new middle school podcasting project on the horizon, but it’s still in testing and I will talk about it here when it matures some more. We are also poised to make some big improvements in online help resources by way of a new knowledgebase starting in January or so.

I did appreciate Christopher Sessums’ recent post on action research and teacher technology integration and told him so. I need to read more blogs like Chris’ and fewer blogs from the leading edubloggers who speak (to me, at least) solely from the ed tech consulting perspective. Other voices in my blog reader include a principal, classroom teachers, school web site developers, graphic design experts, and usability experts.

The upshot of these two points is that I will write when I have something worth writing about! Have a delightful Thanksgiving.

A Good Day for Gallery

I love making information from one part of the school visible to the entire institution. Today, our web site editor and I took over 400 professional photos shot for the new viewbook and posted them into our intranet. We have now made these photos, which we own, available to the entire faculty and staff for use in other publications. Brilliant. I feel the same way about pulling data from one web site to another or from our school information system into our intranet web site. There is so much going on in an institution of this size, but it takes work to make the work of one department useful to others.

The other piece of good news: Gallery’s upload applet (running within Moodle) successfully imported over 400 photos in one big load. We went to lunch while it ran!

Employee In-Kind Giving Programs

Some companies offer their employees the benefit of making an in-kind donation to a non-profit organization of their choice. Rather than giving a cash gift to the organization, employees may select products at employee prices to give. This is a great opportunity for schools, as employee prices are typically one-third of the retail price! For a $300 gift, you can get a laptop computer! As we provide laptop computers to students on financial aid, a recent parent gift just saved our financial aid budget $7,000!

Note that you must publicize the option tactfully, as companies want the employees to dictate all aspects of the gift. Program information is typically not available on public company web sites.

School colors and graphic design

Our school just made the daring move of changing the primary colors used to represent the school in print and web materials. Note that we didn’t actually change our school colors of blue and white, which are still used on uniforms, the school flag, and memorabilia. Most schools chose their colors well before they began to take graphic design seriously.

Microsoft Windows is blue. Mac OS is blue. IBM was once called “big blue.” Boys wear blue. Blue is a safely inoffensive color that carefully avoids inspiring passion or enthusiasm. Our new marketing colors evoke the boldness, energy, and warmth of this institution. This statement from the field of color theory explains nicely.

Blue is the color of the sky and sea. It is often associated with depth and stability. It symbolizes trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.

Blue is considered beneficial to the mind and body. It slows human metabolism and produces a calming effect. Blue is strongly associated with tranquility and calmness. In heraldry, blue is used to symbolize piety and sincerity.

You can use blue to promote products and services related to cleanliness (water purification filters, cleaning liquids, vodka), air and sky (airlines, airports, air conditioners), water and sea (sea voyages, mineral water). As opposed to emotionally warm colors like red, orange, and yellow; blue is linked to consciousness and intellect. Use blue to suggest precision when promoting high-tech products.

Blue is a masculine color; according to studies, it is highly accepted among males. Dark blue is associated with depth, expertise, and stability; it is a preferred color for corporate America.

Avoid using blue when promoting food and cooking, because blue suppresses appetite. When used together with warm colors like yellow or red, blue can create high-impact, vibrant designs; for example, blue-yellow-red is a perfect color scheme for a superhero.

Light blue is associated with health, healing, tranquility, understanding, and softness.
Dark blue represents knowledge, power, integrity, and seriousness.

The sad state of accessibility for the blind

There is nothing like serving one of your own to draw attention to a neglected issue. I have spent a lot of frustrating time in the last few weeks investigating accessibility in news web sites for our school counselor, who cannot see. George is a whiz with email, but he has never surfed the web due to the frustrations of getting around. What sighted people take for granted — quickly scanning a page for important visual items — is a completely different experience with a screen reader. George’s program, JAWS, works sequentially from the top-left of a page, which means that it often gets stuck in dozens of links on a page before reaching any useful content at all.

The technology needed to make web sites accessible to George is extremely easy to implement. Simple alt key shortcuts can be implemented on any link. Although the W3C standards include detailed provisions for accessibility, they do not mandate the use of alt key shortcuts, perhaps because they were not in regular use when the standards were first written. In the absence of clear standards, a number of universities in the U.K. publish accessibility guides for their sites, in which they list the alt key shortcuts they have decided to use. No so for U.S. news sites.

One theory out there is that web site developers have been quick to hop on new technologies, such as popup menus, Flash content, and AJAX layers. However, there seems to be a pretty high level of disinterest at play when the New York Times web site does not publish an easy-to-find accessibility guide or use alt key shortcuts. Making sites accessible to the vision impaired does not seem to make the feature list for most major sites.

Yahoo! News for PDA

Fortunately, my search for accessible online news sites ended with a small silver lining. I recall learning a little bit about PDA formatted web sites a few years ago, so I tried to search for PDA versions of popular web sites. These days, these sites are pretty well-hidden from the regular web browser. The Blackberry site does not return a HTTP response. The New York Times site requires TimesSelect login. Fortunately, both Yahoo! and Google news sites work. The Yahoo! site seems the better of the two, storing articles within the site and presenting numbered alt keys that are easy to use.

Another upshot of this experience is that I am going to ensure the accessibility of our Catlin Gabel web site when we redesign its architecture and technology this summer. When you store all your content within a database, it is simple and imperative to provide an accessible formatting option. Even better than allowing visually impaired users to jump over the navigation, why not present a text-only layout with most of the navigation at the bottom. Other options exist as well, such as using div tags to change the order in which screen elements are read. We will learn more about these when we reach the development phase of this project.

Want to upload an image into a Moodle wiki?

You can’t. At least in some circumstances. That’s what I have concluded after many hours of investigation. It appears that the Moodle wiki module included with Moodle 1.5 and 1.6 (based on eWiki) has a bug that does not allow students to upload images into the wiki even when the “allow binary files” option is checked. This differs from other modules such as forums, in which it works just fine. Students may still link to images stored elsewhere (even in Moodle), but they can’t upload the image when they need it. For research projects, this may be okay, because students often get images from other web sites, but it runs counter to many users’ natural instincts to post files when they need them.

While admins get the full image upload popup, students only get the following window.

student insert image window

I have tested this in three Mac browsers and both Windows and Linux-based Moodle 1.6.1/1,6,3 installations. I also tried uprading to nWiki, the new wiki technology being developed for Moodle 1.8. One suggested workaround, uploading the image into the wiki as an attachment and then adding it via [internal://filename.jpg] notation is awkward and only works on my Linux installation, not in Windows. Another suggested workaround, posting the image to a discussion forum and then linking to the image URL, is too disruptive to a person’s work process.

The following post suggests that the error may lie with the HTML editor toolbar rather than the wiki module itself. Could this problem be platform-specific? Maybe this is why there is only a small amount of discussion of this issue on the Moodle forums.

Let me know if you have the same experience and whether you know of a fix out there. Thanks.
