Kurt W. Fischer (June 9, 1943 – March 30, 2020) was an educator, author, and researcher in the field of neuroscience and education. Until his retirement in 2015, he was the Charles Bigelow Professor of Education and Director of the Mind, Brain, and Education Program at Harvard Graduate School of Education .
The theorem was first formulated in Fisher's 1930 book The Genetical Theory of Natural Selection. [4] Fisher likened it to the law of entropy in physics, stating that "It is not a little instructive that so similar a law should hold the supreme position among the biological sciences". The model of quasi-linkage equilibrium was introduced by ...
Kurt W. Fischer advanced a theory that integrates Piaget's notion of stages in cognitive development with notions from learning theory and skill construction as explained by the cognitive psychology of the 1960s. [19] Fischer's conception of the stages of cognitive development is very similar to that of Case. That is, he describes four major ...
Fisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males and females. A. W.
Juan Pascaual-Leone was the first to propose a neo-Piagetian stage theory. Since that time several neo-Piagetian theories of cognitive development have been proposed. [12] These include the theories of Robbie Case, Grame Halford, Andreas Demetriou and Kurt W. Fischer. The theory of Michael Commons' model of hierarchical complexity is also ...
The Genetical Theory of Natural Selection is a book by Ronald Fisher which combines Mendelian genetics with Charles Darwin's theory of natural selection, [1] with Fisher being the first to argue that "Mendelism therefore validates Darwinism" [2] and stating with regard to mutations that "The vast majority of large mutations are deleterious; small mutations are both far more frequent and more ...
Fisher also contributed to the understanding of human blood groups. [28] Fisher has also been praised as a pioneer of the Information Age. [29] His work on a mathematical theory of information ran parallel to the work of Claude Shannon and Norbert Wiener, though based on statistical theory.
The peacock tail in flight, the classic example of an ornament assumed to be a Fisherian runaway. Fisherian runaway or runaway selection is a sexual selection mechanism proposed by the mathematical biologist Ronald Fisher in the early 20th century, to account for the evolution of ostentatious male ornamentation by persistent, directional female choice.
