The Law of Unintended Patterns

For any matched pair of non-trivial examples
there exists (n == 1) pattern that the creator of the examples intended to highlight
but there also exist (1 < n <= infinity) unintended patterns that students will find.

It’s difficult to live-code programming examples… the conventions we use by habit often invite students to find the unintended patterns.

As an instructor, how do I get students to see the single pattern in which I’m interested, rather than the possibly infinite patterns that exist? Or, is that even the best goal? Should I, instead, be encouraging students to look beyond the first pattern they detect in order for them to appreciate the inherent complexity of interpretation?

Designing Computing Spaces for Collaboration

Classrooms are, at their best, learning communities. Unfortunately, with the rise of the PERSONAL computer (PC), computing classrooms have evolved to meet the needs of the computer, rather than the learner. In so doing, often both the needs of the computer and the learner go unmet. Consider the all too typical situation of a room that has been retrofitted to provide dozens of electrical outlets and network connections, but with no improvements in the air conditioning. It seems to have escaped the attention of the room’s designers that computers, even at idle, generate many BTUs of heat… as do students! The body heat from 15-20 students in a room is considerable.

I stress the personal aspect of personal computer here not because I think you don’t know what I mean by a PC. Rather, it’s because that individual context, the idea that the computer is meant for individual, personal use is important in a learning environment. PCs are designed with the individual in mind. Even when the idea of having multiple users was adopted in consumer PC operating systems, the idea was still that one user would be logged in at a time, working alone. In the more advanced operating systems, you can switch between the individual user contexts.

What you can’t do easily with a personal computer is collaborate, and that’s a problem for educational uses of computers both in terms of the operating system design and the design of computing classrooms.

Ideally, computing classrooms would include

  • room configurations that support collaboration
    • movable tables to support small groups, seminars, and lectures
    • ready access to power outlets, both on the walls and in the floor
    • wired network access for a portion of the users, since not all devices support wireless
    • sufficient wifi coverage to support a full class, all downloading needed software at the same time, since not all devices support wired connections (e.g., iPhones, iPads, Macbook Air, other ultrabook format computers)
    • a high-resolution projector, so that applications that use significant screen real estate can be projected: Photoshop, Blender, Xcode, other programming integrated development environments.
  • network storage that supports collaboration (where will students and groups share files?)
  • a storage strategy that supports collaboration (how to handle collisions among students saving?)
  • software that supports collaboration
    • MoonEdit,
    • SubEthaEdit,
    • Google Docs,
    • Wikis,
    • GIT,
    • etc.

Cult of Ignorance ~ Isaac Asimov

Quote

There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that “my ignorance is just as good as your knowledge.”

― Isaac Asimov

"Will this be on the test?"

Students reasonably need to understand what is expected of them in a course. Educators need to make clear what is acceptable and unacceptable student engagement with a course. The syllabus is the natural place for this to happen, as long as both students and educators recognize it for what it is.

Students shouldn’t approach the syllabus as the maximum they’ll do… education is about expanding your horizon! The syllabus is the absolute minimum you should expect to do; the engaged and interested student will use it as a lower bound, not an upper bound.

Steven Paul Jobs, 1955-2011

Quote

Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

— Steven Paul Jobs

“Don’t be ‘a writer’. Be writing.” ― William Faulkner

Education researchers have shown that the most powerful way we learn is by trying to articulate what we know, believe, and feel (Connally, 1989). The creative process of transforming what is inside our heads into a form that can be shared with others is difficult but absolutely necessary for meaningful learning to take place. How many times have you passively listened to someone (ME!) talking about a topic thinking to yourself how boring it was or how obvious or how random, but when you later tried to explain it to someone, you found it nearly impossible to do so?
