When authors, presenters, leaders, and others describing “paradigm-changing” practices and ideas, make sure to ask if they are talking about a Kuhnian paradigm. Here is my take on the four characteristics of paradigms: According to Kuhn (1970), paradigms are comprised of four components, and a paradigm shift requires new understanding be recognized and implemented within Read More

A Little #edtech History: Connecting Schools
Once the World Wide Web became available in the mid-1990’s, the Internet changed from being a resource for academic and government researchers to being a tool for commerce and the people. Many educators recognized the World Wide Web as an opportunity for students to access previously unavailable resources. Because few schools had the network infrastructure Read More
A Little #edtech History: Computers Arrive on Desktops
In the 1970’s computers entered the consumer market, and hobbyists began purchasing computers. By 1982, personal computers could be purchased for less than $1000, and amateur enthusiasts (including children) were writing their own programs to satisfy their own interests and curiosities. In that year, Joseph Deken, a statistician working at Stanford University who had received Read More
Managing Extraneous Cognitive Load
In authentic learner tasks, the cognitive load of the activities will likely be greater than the cognitive load in highly controlled instructional settings. By preserving the context in which the problems exist in the real world, educators increase the opportunities for intrinsic and germane cognitive load, but also the potential for extraneous cognitive load. There Read More
The Baldwin Effect: An Old Idea from Biology that Explains Organizational Learning
In biology, the Baldwin Effect was proposed in 1896 to suggest that learned behaviors could become a part of the biology of individuals and populations. Although this hypothesis did not stand the test of empirical observation and has been discredited as an effect in biology, it has been resurrected as a model helpful for understanding Read More
#edtech for #edleaders: Understanding IT Management
One focus of professional development relative to information and computer technology (ICT) in schools has been managing it. When computers first arrived, and machines were stand-alone devices, individual educators were able to manage the computers in their classrooms with independence; software was purchased for single machines and printers and similar peripherals were connected to specific Read More
Ethics and Data Collection in Schools
A part of all education research is recognizing one’s responsibility to proceed in a manner that respects the subjects, the process, and the community. Ethical researchers do not endanger the physical or emotional health of subjects, and they take steps to ensure the privacy of subjects and preserve subjects’ right to withdraw without penalty. Also, Read More
Learning New Technologies
I have been workin with faculty who are trying to learn to use a new web service recently. They have been growing frustrated as the interface is not intuitive (and it is poorly designed, but don’t tell anyone I said that). Many have said they would stop using the service if they could but they Read More
#edtech for #edleaders: Correlation does not Mean Causation
Correlation does not mean causation… just because your computer malfunctioned soon after you (or someone else) did something to a computer or a system or your network or your software and it malfunctioned soon afterwards it does not mean the change cause the problem.
Be A Bricoleur
Claude Levi-Strauss (a French anthropologist who died in 2009 less than a month before he turned 101) introduced the term bricoleur to western thinkers to describe a “jackof- all-trades” approach to technology (and other practices). He suggested the term after observing individuals in other cultures who would explore the potential uses of various new tools Read More
