Cognitive load is a well-known and established theory. Basically, it posits humans have a limited amount of cognitive processing power available at any moment; game theorists would declare our cognitive capacity is a zero-sum quantity. What is used for one purpose is unavailable for other purposes. In classroom, we want to limit extraneous cognitive load Read More

On Familiarity and Novelty
Teachers who create classrooms in which students pay attention are skilled at finding the correct balance between familiar and novel. Human brains are adapted to figuring out “just the right amount of change.” The logic behind this adaptation is simple: If a situation is familiar, then it is predictable so we have a sense of Read More
Thoughts on Standardized Education
My career has approximately coincided with the history of personal computers in schools. I was an undergraduate student when “computer” meant a device that sat on a desktop and was turned on only after placing a diskette in the drive that loaded the only program that could be used during the session. The display was Read More
Thinking About Connectionism
For most of human history, communication was an aural or gestural activity. We spoke and we made gestures, other heard and saw our movements. In both cases, the communication was ephemeral. Unheard words and unseen gestures are lost. There is evidence of humans creating painting and other artifacts which presumably were intended for meaningful communication, Read More
On Reducing Bias in Online Teaching
I found this short answer to the question, “How can we reduce bias in online teaching?” which I composed a couple of years ago. I’m curious about my suggestion that Standard English is a method whereby we can reduce bias. I’m not sure I would give that suggestion now. Is that inclusive language or not? Read More
Assumptions Educators Make
Education is about changing humans. When our students leave, we hope they can do things, see things, and think things they could not before the class. That reality is rich with the potential for abuse and history shows it has been abused, but there is equal reality that education can be co-opted for other goals. Read More
Latent Learning
I’ve read an interesting article recently that challenges what appears to be to orthodox view that performance on tests and other assessments is predictive of long-term learning and the ability to apply what one has learned on other situations. Among the several points that support the authors’ claims are seemingly contrary observations. Latent learning is Read More
Performance and Learning
Recent decades have found educators sharply focusing on performance. This arises from the dominance of standards to guide curriculum. At all levels of education, we define what it is that students are supposed to know and do, translate that into learning objectives, then check students’ performance on assessments that (ostensibly) measure the degree to which Read More
Technology Literacy
Technology literacy has been on my mind. My definition is inexact, but I can recognize it in people. You might be able to judge your own technology literacy by reflecting on how you react to new technology. For this post, I am going to ignore those who enthusiastically accept any new device. These folks are goo to Read More
A Gap in Education
The foundational idea of education is that students are able to “do something” after the process is complete that they could not do before. What students can do depends on the experiences that comprise their education. There seems to be two competing versions of what we hope our students will be able to do after Read More
