While analyzing some interview data in the last year or so, my colleague and I discovered our coding was remarkably consistent with Roger’s (2003) theory of the diffusion of innovations. For me, this illustrated exactly why we spend time and energy conducting research, consuming research, and returning to the research when we are unsure of Read More

Updating UTAUT Instrument
Technology acceptance is an idea that has recurred in this blog, and with good reason. I have used it as a guiding principle in the design of instructional technology for more than a decade. Specific posts where it is featured are: #edtech for #edleaders: Measuring Technology Acceptance The Application of Technology Acceptance to Educational Design Read More
Usability in #edtech
Usability is a factor that has been recognized as playing a role in the widespread adoption of ICT to meet the strategic and logistic goals of businesses and industries other than education. Designers recognize that usable systems decrease extraneous cognitive load, and thus facilitate knowledge building. In general, usability is associated with the extent to Read More
A Closer Look at Educational Data
Educational data has been a recurring theme on this blog. In this post, I continue considering the nature of data in education and the nature of data in science… comparing and contrasting the two. Constructs and Instruments Scientists are always specific about what they are measuring, and there are accepted methods for measuring these quantities. Read More
Connectionism Makes Sense
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
Factors Affecting Diffusion of Innovation
Diffusion of Innovation (Rogers, 2003) is a well-known theory that predicts and explains who new ideas and practices spread through communities. The stages of adoption are perhaps the most widely used aspect of this theory, but other aspects are useful as well. Rogers identified several measurable factors that are associated with the diffusion of innovations Read More
WEIRD Perspectives
Much of the science surrounding teaching and learning has occured in cultures that are white, educated, industrialized, rich, and democratic (WEIRD). While I am not criticizing that focus, especially by researchers and practitioners who work in those cultures, I do suggest we must use care in extending what we “know” about teaching and learning from Read More
Kuhnian Paradigms
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
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
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
