Why Curiosity Enhances Learning | Edutopia - 40 views
-
It's no secret that curiosity makes learning more effective and enjoyable. Curious students not only ask questions, but also actively seek out the answers.
-
While it might be no big surprise that we're more likely to remember what we've learned when the subject matter intrigues us, it turns out that curiosity also helps us learn information we don't consider all that interesting or important. The researchers found that, once the subjects' curiosity had been piqued by the right question, they were better at learning and remembering completely unrelated information
-
if a student struggles with math, personalizing math problems to match their specific interests rather than using generic textbook questions could help them better remember how to go about solving similar math problems in the future.

Sobering Finds in Most Comprehensive Study Ever on Antarctic Ice Loss - 7 views
-
Scientists are calling it the most complete picture ever of ice loss on the southern continent.
-
Antarctica was melting at a steady rate — one-fifth of a millimeter per year — before 2012, when the rate suddenly tripled and stayed at that pace. The current melt rate is now faster than at any time over the past quarter century.
-
Their findings showed that the decisions we make over the next decade will determine whether or not Earth is locked into an additional 3 feet of sea level rise.

Can Mary Shelley’s Frankenstein be read as an early research ethics text?
-
Frankenstein is an early and balanced text on the ethics of research upon human subjects and that it provides insights that are as valid today as when the novel was written.
-
Mary Shelley conceived the idea for and started writing Frankenstein in 1816 and it was first published in 1818.1 In its historical context, the earlier 17th and 18th centuries had seen the early signs of the rise of science and experimentation. Francis Bacon (1561–1626) had laid the theoretical foundations in his “Great Insauration”2 and scientists such as Boyle, Newton, and Hooke developed the experimental methods. Sir Robert Talbor, a 17th century apothecary and one of the key figures in developing the use of quinine to treat fevers, underlined this: “the most plausible reasons unless backed by some demonstrable experiments seem but suppositions or conjectures”.3

Contemplating the consequences of Constructivism - The Learner's Way - 21 views
-
learning is a process which occurs within the mind of the individual as they process stimuli arriving from their sensory buffer from their environment (broadly speaking), into working memory and onward into long-term memory.

Constructivism is one of those ideas we throw around in educational circles without stopping to think about what we mean by it. They are the terms that have multiple meanings, are at once highly technical and common usage and are likely to cause debate and disagreements. Constructivism in particular carries a quantity of baggage with it. It is a term that is appropriated by supporters of educational approaches that are in stark contrast to the opposing view; constructivism vs didactic methods or direct instruction. The question is what are the origins of constructivism and does a belief in this as an approach to understanding learning necessitate an abandonment of direct instruction or is this a false dichotomy?
