A Lifelong Learner Shares Thoughts About Education

  • Writing books TLDR?

    From Poynter, this two page PDF distills down writing.

  • I keep thinking about this article https://www.middleweb.com/41193/inviting-mr-rogers-into-your-sel-classroom/ and the need to bring Mr Rogers back. I think it is more important as anxiety increases and the climate of the world continues to become more aggressive and toxic.

    It may well be the missing component that has been forcibly removed on the PD death march that schools are engaged in which prioritizes everything that can help an administrator without actually leaving any time to be just a teacher.

  • Almost time to start the detailed planning for the 2019-2020 school year and among the things I relearned this summer at CS4Teachers at the UW was design charrettes. This was a lesson worked on with students who do the K12 outreach for HCDE (Human Centered Design & Engineering) program at the U of W and essentially ran like this article https://www.hcde.washington.edu/news/charettes-k-12-outreach. A quick glance around the UW campus found other places like the CBE (College of Built Environments) http://archpac.be.uw.edu/new-student-charrette/ using them as well.

    I will start working on the details the week before school starts as I intend to use this as a new student introduction activity in my IB (International Baccalaureate) CS classes. It isn’t because they require that level of expertise, simply that they really lend themselves to organizing and teaching the process and time for designing and implementing a project which is a key for the year for that program.

    It would be really cool to put it into play in the regular course, perhaps in outlining a Mobile game interface, mostly because the Marvel App (https://play.google.com/store/apps/details?id=com.marvelapp) made ALL the difference along with the practice.

    Reflection: I learned Design Charrettes a few years ago and yet they didn’t jump out at me as they did now that I wish to have a quick way to provide a fundamental design experience to an entire class without lecturing.

  • There is the theory that the HDMI output of the Raspberry Pi is only initialized if a monitor/television is connected and powered up before a Raspberry Pi 3 is turned on.
    Yet when I connect my Raspberry Pi 3 to a old Panasonic Plasma display the Raspberry Pi actually turns on the device and the screen activates every time.
    Not so with the Vizio P series I just hung on the wall.

    Aside: some of the Panasonic HDMI ports were damaged in a painting disaster…never use a 20lb weight to hold a tarp.

    With the Vizio, whether the monitor is on or off and the correct HDMI port is selected or not, the Raspberry Pi 3 simply never brings up HDMI output.

    Edit the /boot/config.txt file and uncomment these two lines

    #hdmi_force_hotplug=1

    #hdmi_drive=2

    And the device works every time from every state.  The first line is as it appears, the second activates HDMI and enables sound rather than DVI mode which does not.

    I did like that the Vizio takes edits the HDMI connection in its table to Raspberry
