In contrast, many of my colleagues concerned with the quality of science education in other disciplines moan and groan about how hard it is to get college faculty to pay attention to research on learning or to change their teaching practice. So how–by what mechanism–does the Cutting Edge approach work? Here's an idea. More
an earlier post on temporal thinking, these are fields of science or scholarship that pay careful attention to the timing and sequence of events, and use timing and sequence to provide constraints on causality. Our concept map shows nodes for Cosmology, Geology & Paleontology, Archeology, History, and Developmental Psychology. More
First, Dana discovered a fabulous cartoon, the exactly speaks to the topic of the post. Wonderously, the cartoon is published under a creative commons license, so I can reproduce it here for you: More
(Co-author Dana is Kim's 15-old daughter, a veteran of the New York State Earth Science Regents course, now taking integrated biology and chemistry. She is also an avid reader, currently working her way through the 42 Discworld books of Sir Terry Pratchett.)In The Science of Discworld, Terry Pratchett, Ian Stewart & Jack Cohen make the case that education necessarily involves telling "lies to children." We realize that telling lies to children is a pretty common part of traditional parenting (Santa Claus, stork, etc.), but in school! in the citadel of learning and truth! How can this be? More
"Embedded energy" refers to the energy that was used to create an object–including mining or growing or catching the raw materials, manufacturing and assembling the pieces, transporting the raw materials and finished product, and installing the object in its place of use. A spoon, to take a simple example, required energy to mine the ore, to smelt the ore to make the metal, to shape the metal into spoon shape, plus more energy to transport ore to the smelter, metal to the factory, spoon to the store. Embedded energy is contrasted with the energy required to power or use the product during its lifetime.
There is a somewhat parallel concept, which refers to the knowledge and thinking that was required to design and perfect the object. More
