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
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
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
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
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
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
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
Storytime… About 20 years ago, I was looking to refocus my career. I had an interest in library science, so I found an online program and singed up for two courses with the intent of matriculating in the master’s program before the deadline during which I was to study. The two courses were interesting. I Read More
Historian and philosopher Theodore Roszak (1994) minimizes the role of information in human cognition, and he even observes “humans think with ideas, not with information” [emphasis in the original] and affords ideas a central place in the human cognition by continuing, “Information may helpfully illustrate or decorate an idea; it may, where it works under the guidance of a contrasting idea, help to call other Read More
Much of the 20th century recitation script for education, in particular the articulation of measurable goals and the focus on efficiency, was based on the assumption that becoming educated was a tame problem. So that curriculum goals could be achieved efficiently, the problems that became learner tasks were de-contextualized; the context of rich information and Read More
