In recent decades, there is rich evidence that cooperation rather than competition is a strategy associated with long-term survival of life. Lynn Marguilis and Dorian Sagan point to evidence that mitochondria and chloroplasts (organelles found in multicellular organisms such and plants and animals) were originally independent organisms that formed cooperative relationships with other organisms to Read More
Theory, of course, permeates everything we do. -Stephen Jay Gould Many educators would disagree with Gould’s observation. For these teachers, “theory” is conflated with “silly ideas for which I have no time, I need to cover the material.” I understand this approach, much that we do in education can be done without directly indicating the Read More
The concept of the paradigm shift was introduced in the 1960’s and revised in 1970 by Thomas S. Kuhn in his influential book The Structure of Scientific Revolutions (Kuhn 1970). Kuhn was the first to publish this account of how knowledge in science advances: Scientists conduct experiments and carry out their observations to study unanswered Read More
Lev Vygotsky was a Russian psychologist who lived from 1896-1934. He was relatively unknown to educators until the 1960’s and 1970’s when his work was rediscovered and interpreted. (Many believe the difficulty with reading Vygotsky’s work arose from the little editing he did during his end-of-life brain dump during which he recorded as many of Read More
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
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 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
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
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
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
