Grading

Ugh. I spent too much time today and yesterday doing grading. I shouldn’t be this slow at it. Here’s the general process:

Look at 5–10 submissions and note what are the most common errors. From this, a rubric can be generated. Then, comb through all assignments and dock points according to the rubric. Even after […]

Tricks of the Trade

Today, Howard Rheingold was searching for examples of clear posts in which to use as examples of online communication. One of the respondents identified a really good series set of descriptions answering the question, What is it like to have an understanding of very advanced mathematics? (Interestingly Terry Tau is referenced quite often.)

That reminded […]

Introverts

Even though extroverts make up the majority of people on this pale blue dot, I happen to feel comfortably at home in academia. The profession seems overwhelmed with introverts. It’s not as if we are shy, or afraid of interaction, or uncomfortable around people. Rather it’s that we prefer the quiet solitude of our own […]

Great Presentations

Back when my interest in teaching was only just a spark on the kindling of my brain, I started to investigate the tricks of communication. Up to that point in my life I had completely underestimated the importance of communication. I thought, as any myopic engineer would, that sound ideas will speak of their own […]

Transforming Heuristics

Many of the real problems in the world are NP. Things like Scheduling, Register Allocation, Routing packages, etc. In solving these really hard problems, we invent heuristics. Typically such heuristics are specific to the problem domain. For example, UPS might exploit certain characteristic about the geographical layout of the country; they face a certain subset […]

Public School, it is a Prison

How the Public Schools Keep Your Child a Prisoner of the State by Karen De Coster, has a few interesting links about how public schools act like prisons for both mind and body.

A really well researched article on equality via the school system: “Compulsory schooling not only fails to achieve its egalitarian goal, but […]
