Cases Cracked!

Apple’s flimsy cases have caused us grief again. Out of our 280 student machines, we are sending 60 to Apple for case repair. Pictured below are half of the boxes and some of the computer being prepared for mailing. You can imagine how long it takes to complete the paperwork and mail 60 boxes. Meanwhile, the students do not have their computers.

Here is an example of case cracking. It’s important to send these for repair now, because Apple covers the repair if the cracking only appears on the edge. If the crack spreads around the corner, then Apple consistently claims it was dropped and charge for the repair. Our students take the blame for normal handling of their computers in a school environment.

Is the MacBook Pro aluminum unibody case better? After one year, we have seen almost no case damage due to cracking, not surprising given that it is made of thick aluminum. However, check out this nasty crack along the flimsy plastic hinge cover!

Firmly On the Ground

Do you run a 1:1 student laptop program? Do your teachers and students do all of their work in the cloud, without any local system configuration? I have two questions for you.

What do you do when no cloud equivalent exists for a desktop application?
How do you provision network, antivirus, and security configurations?

Our desktop applications include:

  • Fathom
  • Geometer’s Sketchpad
  • ComicLife
  • Inspiration
  • LoggerPro
  • Flip4Mac
  • iBackup
  • Microsoft Office
  • Adobe Creative Suite

System configuration includes:

  • 802.1x system profile or WEP pre-shared key
  • Custom machine name (for network identification)
  • DHCP reservation (to assist with network identity)
  • Server certificate for Global Address List lookups
  • Sophos antivirus client
  • SafeConnect (network access control) client
  • Altiris (inventory and remote control) client
  • Allow remote administration via Apple Remote Desktop
  • Local administrator account for Apple Remote Desktop access
  • Apple administrator account to facilitate Apple repairs
  • Root user for some remote tasks

Voice recognition still not yet there!

For how many years has it seemed that voice recognition was just about there? This year sees renewed interest in the software, especially for students who have graphomotor coordination issues. These students have difficulty getting the many ideas in their heads out onto paper or computer quickly enough.

Sometimes, the Dragon Dictation app for iPhone does pretty well. This time, it didn’t!

What it heard What I said
Alina’s Becky I figured out the problem with a smart card and science one turns out that it’s a setting in the displays preferences panel the gamma level which controls the blackness of the image I can set incorrectly so I will send you a how to Africa together but the good news is you can make the image look better just by taking a setting on your laptop talk to you soon. Bye-bye Aline and Becky,

I figured out the problem with the Smart Board in Science 1. Turns out that there is a setting in the Displays preferences panel — the gamma level — which controls the blackness of the image. It can be set incorrectly, so I will send you a how-to, or we can walk through it together, but the good news is you can make the image look better by changing a setting on your laptop.

Talk to you soon,

Bye.

21st Century Learning and Progressive Education

Many education technology bloggers (1, 2, 3) have issued a call to transform schools into “21st century” learning institutions. Speaking broadly, these schools would emphasize student-centered instruction, project-based learning, and lots of technology use.

These authors make frequent reference to popular new books that describe how society is changing as a result of ubiquitous communication and productivity technologies. Titles include Switch (Heath and Heath), The World Is Flat (Thomas Friedman), A Whole New Mind (Daniel Pink).

I think they’re reading the wrong books. Adding more technology does not change teaching practice. The educational revolution they describe already has a name: progressive education. Over 100 years old, progressive education emphasizes learning through experience, the unique qualities of each learner, and the critical role of education in a democratic society.

Let us adopt a new reading list for 21st century learning, grounded in education theory and schools rather than technology and social change.

John Dewey: Democracy and Education, Education As Experience

Howard Gardner: Multiple Intelligences, Five Minds For the Future

Alfie Kohn: Punished By Rewards, The Homework Myth

Nell Noddings: The Challenge to Care in Schools

Focus On Assessment

Students created an eight-page newsletter entirely on their own, learning new tech skills as needed, and working exclusively during homeroom periods.

Last year, I co-taught fourth and fifth grade technology classes with the homeroom teachers. The first time through, I focused primarily on designing effective learning environments for elementary students. The best activities provided open-ended project opportunities for the kids, taught some basic skills, and tied tightly to homeroom activities.

This year, I plan to emphasize assessment design in my planning. Wiggins and McTighe remind me that assessment design ought to precede lesson design. Identify the learning goals and objectives and then construct assessments to determine student mastery. Paul Black suggests that I vary assessments in form and provide students with feedback useful for further improvement. Bill Fitzgerald makes a push for portfolio-based assessment.

I will certainly tap into the common forms of assessment used at Catlin Gabel. I only teach one 40 minute period per week (the homeroom teachers cover the other 40 minute period). The teachers have designed effective assessments and put a lot of energy into building students’ familiarity with them. Rubric-based assessment is common, which fits the project-based tech curriculum nicely. It also suggests that I could have the kids self-assess, which would build their self-knowledge, provide them with formative feedback, and assess their skill and content mastery.

Students also build summative portfolios in homeroom, which they finalize and share at the end of the year. I could tap into that, but since nearly all tech activities are already grounded in a homeroom project, students may already build portfolio artifacts around them. It seems counterproductive to insist on a technology portfolio piece, when we go to great effort to teach technology as a tool that helps the students get homeroom work done.

Also worth remembering: I have 88 students and a full-time job back in the IT office! I am unlikely to find hours to pore over long assessments. However, if students post assessment products to our course website or their network folder, that will help me review these items quickly and write feedback and notes for future reports.

What assessment techniques do you use with elementary-age students? How do you record them in a way that is useful for future reference?

Online Admission Application

This summer, I put the finishing touches on our new online admission application. We have had online inquiries for two years, including parent information, student information, tour and visit scheduling, and application forms download (PDF). I ported the code from a previous version that I wrote for my previous school and then modified it for this multi-divisional institution.

Over the years, online admission apps have evolved from a convenience for international applicants to an expectation of many parents. Many of the new features are pretty simple: a student statement requires a lot of thought from the author but only a set of textfields from the site!

I tried a new approach with teacher evaluations. The website allows the parent to send an invitation email to a teacher, who then clicks on a link in the email to visit our website and write the evaluation. I am looking forward to seeing how well that system works and making changes if necessary.

The application pulls applicant information from Education Edge as needed. It also shows the status of received forms by querying EE checklists, which our staff update as forms are received. Online payment uses Ubercart functions to create a virtual “cart” behind the scenes and submit payment details for processing.

Having a website system changes some aspects of the application process. The instant we open the website, families may start working on their applications. Free responses are limited not by a number of pages or words but rather by string length in characters. Families will be able to start and complete an application just before midnight at the application deadline, if they so choose. Admission staff will be able to measure the number of incomplete applications in process if they wish. We have a “finalize” link for families to submit their app, but we will need to decide what to do with applications that are complete but not actually marked as final and submitted.

The name “Dwee” is fictitious (in case you were not sure)!

Creeping closer …

Today, we received the first student laptops for annual maintenance, which also marks the unofficial end of summer project work within the IT department. From here on in, we fully devote ourselves to laptop maintenance and responding to user requests as teachers return to school and staff prepare for the start of term.

We finished nearly all of the faculty laptop computers last week, save those that required a trip to Apple to repair a broken or malfunctioning part. They required a lot of work. We moved all of the Windows machines to 7, since XP is now out of support. The Macs required extensive research to devise the best configuration for printers, wireless access, and network access. Attempts to automate the process were regularly foiled. It took far too much effort to reach a point of reasonable confidence that the configuration will work effectively. Hopefully, things will go more smoothly for the student machines.

Signs of the impending school year abound. Divisions heads meet this week to plan for the year. Some teachers have shown up for summer curriculum planning meetings. I’m not actually certain what all goes on next week, but August 30 brings the official start of the school year for teachers. They will attend division retreats and opening meetings. Grades 6-12 start before Labor Day weekend, whereas grades PS-5 start after. Oregon requires only 160 days of school in the year, well below the 180 in our neighboring states.

Macs and the Enterprise Network

Configuring Mac laptops for our new 802.1x network is proving more difficult than expected. It appears that only OS 10.6 is compatible with WPA2 Enterprise networks, and even then, they don’t always connect all of the time. At the moment, we are looking at the following:

10.6 clients: 802.1x system profile with saved user credentials

10.5 and below: WEP with pre-shared key

On startup, the process that authenticates a user via 802.1x does not always launch at the right time, leaving the user in no man’s land. The user than has to turn wireless off and on to get it to try again. If the user brings the computer from home to school and wakes it from sleep, then the process is not running and then cannot auth to 802.1x. Fortunately, once connected, the system seems able to reconnect reliably when waking from sleep. We have provided a small, custom app for users to easily reset the wireless card.

Too bad that Apple has not yet got this right. It feels so 2001 to run WEP for some of our users, especially on our brand new wireless network. Our Windows client setup has been flawless.

“Technology to be in every room”

Here’s yet another Smart Board love affair. One-third of district classrooms had a Smart Board, so the district decided to install a Smart Board and projector in all classrooms. I would like to know what decision-making process led to this $2m expense. What if only one-third of the teachers used the technology effectively? How do these devices help students actively learn?

If we could give every student a computer, we would,” said Rick Green, director of information technology for the 24,000-student district. “This is as close as we could get.

Smart Boards enable a teacher to organize and present content visually. Computers allow students to engage with and produce content. Surely small classroom laptop sets would have come closer to the expressed ideal?

“Magic” Trackpad Misses the Point

I don’t imagine that Apple’s new “magic” trackpad will feel at all like the touch experience of the iPhone and iPad. The beauty of a touch surface is that you’re virtually touching the user interface itself. Apple’s new trackpad is a useful alternative to the mouse, but it’s still just an indirect interface to the computing environment. Will Apple produce a touch-screen iMac and external display? It would likely tire the arm to repeatedly reach for the screen.
