When I was studying biology as an undergraduate, a students asked the physiology about Daltons, the unit used to measure the size of large molecules such as proteins. The professor was so used to using the term, he had to look up the definition so he could explain it to the 250 or so students Read More
Appropriate Proper Reasonable As an undergraduate science major, I came to understand quantitative data; we measured what we observed in the laboratory and in the field and we summarized and evaluated it to draw conclusions about the world as we saw it. Patterns in numbers were our window into the systems we studied. As a Read More
70: Vygotsky and the Zone of Proximal Development Lev Vygotsky was a Russia psychologist who worked in the early part of the 20th century before he died at 38. Many educators who adopt methods that are commonly called constructivist ground their pedagogy in ideas he developed. One that is particularly useful in designing all curriculum Read More
81: Why Theory Matters in Education In many educational communities, existing practice exerts strong influence on the practices deemed acceptable, so attempts to define new goals are met with strong resistance. In this situation, many educators adopt a stance that Paulo Friere, the Brazilian educational philosopher, suggested resembled Aristotle’s concept of doxa, which is practice Read More
54: Cognitive Lod Theory This post complements this earlier one on The Lens of Cognitive Load Theory While technology acceptance is a theory that can explain and predict the decision to use a technology, cognitive load theory (Sweller, Ayres, & Kalyuga, 2011) (CLT) predicts and explains technology use once it has been adopted. CLT is Read More
61: Frameworks Defined A continuum can be created with educational scholars placed at one extreme and educators at the other; educational theory is placed on the extreme with scholars and models of instruction are placed on the extreme with practitioners. Between these two extremes, there exists a gap that must be filled if instruction is Read More
In the vernacular, “theory” is associated with ideas that are incomplete or not necessarily true. Among educators, and other pragmatic professionals such as technologists, theory is often associated with unrealistic or idealistic thinking that has little connection to her or his work The interpretations of theory are unfortunate, however, as theory can inform and focus Read More
This is an initial draft… as time allows, I will continue to develop this post. John Dewey identified four natural impulses of children: to inquiry to communicate to construct to express For experiences to be educative, he reasoned, they must allow students to follow these impulses. If we hold these to be true, and there Read More
Appropriate Proper Reasonable Reflexivity was originally used to describe the effects of social science researchers on the situations they were studying; the presence of researchers affects the behavior of subjects, thus the observations made. More recently, the term has been used to describe the influence of ICT on how people use information and how they Read More
88: Understanding Wicked Problems In the 1973 article, “Dilemmas in a General Theory of Planning,” Horst Rittel, who was a professor of the science of design at the University of California, Berkeley and Melvin Webber, who was a professor of city planning at the same institution, recognized many problems include a social dimension. While many Read More
