Kurzweil accelerating technology

shared by Michael Lucatorto on 03 Jul 11 - Cached
  • The paradigm shift rate (i.e., the overall rate of technical progress) is currently doubling (approximately) every decade; that is, paradigm shift times are halving every decade (and the rate of acceleration is itself growing exponentially). So, the technological progress in the twenty-first century will be equivalent to what would require (in the linear view) on the order of 200 centuries. In contrast, the twentieth century saw only about 25 years of progress (again at today’s rate of progress) since we have been speeding up to current rates. So the twenty-first century will see almost a thousand times greater technological change than its predecessor.
  • An analysis of the history of technology shows that technological change is exponential, contrary to the common-sense “intuitive linear” view. So we won’t experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today’s rate). The “returns,” such as chip speed and cost-effectiveness, also increase exponentially. There’s even exponential growth in the rate of exponential growth. Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity — technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.

education poverty

  • For example, Mel Riddile points out that when one conditions on various measures of poverty, instead of trailing other nations, the U.S. actually comes out on top! He concludes that "when it comes to school improvement, it's poverty not stupid." Poverty causes educational deficiency.

    For example, Mel Riddile points out that when one conditions on various measures of poverty, instead of trailing other nations, the U.S. actually comes out on top! He concludes that "when it comes to school improvement, it's poverty not stupid." Poverty causes educational deficiency. Now, I like to actually have data to play around with, in part because people have been known to lie about politically charged issues and in part because I like to have nice graphs (which are not provided by Riddile). Anyway, it turns out that international poverty data is pretty hard to come by and fraught with interpretational difficulties. On the other hand, the National Assessment of Educational Progress provides test data for most of the states in the U.S., and the U.S. Census Bureau provides data on the percentage of people in poverty by state. I took the NAEP data for 8th grade science achievement and regressed on the percentage of people below the poverty line for the measured states. The two are negatively associated: as poverty increases, science achievement scores decrease according to the relationship in the plot below. (Alaska, Kansas, Nebraska, and Vermont did not meet NAEP reporting guidelines and are not included in the plot above.) The association is highly significant (p=9.98*10-6). I also took pilot NAEP data for 8th grade mathematics achievement and regressed on the percentage of people below the poverty line for the measured states. (Evidently, the NAEP has only just started testing for mathematics achievement, and only eleven states were included in their pilot.) Again, the two are negatively associated. The slope of the relation turns out to be almost exactly the same as for science achievement. The association is not as significant, but it is still significant (p=0.0186). (My guess is the association is less significant in this case because fewer states were measured.) Clearly there is an association between poverty and achievement in science and mathem

self-direction humanism learning db module 4

  • It appears that many adult educators today, especially those recognizing the value of self-direction in learning, operate primarily from humanist beliefs and c
  • It also has been our observation that some instructional designers (and many other educators) seem to have difficulty accepting or incorporating humanist beliefs and instead appear guided primarily by behaviorist or neobehaviorist beliefs and paradigms based primarily on logical positivism, although cognitive psychology is increasingly informing the instructional design field.
  • We consider it important to understand why some of the philosophical differences between the two disciplines exist.

  • instructional design as a separate discipline, has developed from several forms of inquiry: (a) research pertaining to media usage and communications theory; (b) general systems theory and development; and (c) psychological and learning theory. Reigeluth (1983) suggests that the three theorists most responsible for the current development of instructional design knowledge include B. F. Skinner (1954), David Ausubel (1968), and Jerome Bruner (1966). Skinner is identified because of his work with behaviorism and Bruner and Ausubel are recognized because of their contributions to cognitive psychology. Reigeluth (1987) has also compiled information on several other authors, theories, and models he believes important to the development of instructional design as a profession. Gagne (1985), Piaget (1966), and Thorndike (and colleagues) (1928) are other scholars frequently cited as foundational for much of today's thinking about instructional design.
  • As Hollis (1991) notes, "traditionally, instructional technologists have largely ignored the humanists' ideas among all the available theories from which to draw upon and incorporate into their schemes. Theoretically, instructional technology has been based on research in human learning and communications theories. In reality, more borrowing of ideas is needed, especially from the ranks of the humanists" (p. 51
  • Humanism generally is associated with beliefs about freedom and autonomy and notions that "human beings are capable of making significant personal choices within the constraints imposed by heredity, personal history, and environment"
  • Humanist principles stress the importance of the individual and specific human needs. Among the major assumptions underlying humanism are the following: (a) human nature is inherently good; (b) individuals are free and autonomous, thus they are capable of making major personal choices; (c) human potential for growth and development is virtually unlimited; (d) self-concept plays an important role in growth and development; (e) individuals have an urge toward self-actualization; (f) reality is defined by each person; and (g) individuals have responsibility to both themselves and to others (Elias & Merriam, 1980).
  • "If an individual is concerned primarily with personal growth and development, how can that person truly be concerned with what is good for all of society?"
  • The learning environment should allow each learner to proceed at a pace best suited to the individual.
  • It is important to help learners continuously assess their progress and make feedback a part of the learning process. 5. The learner's previous experience is an invaluable resource for future learning and thus enhancing the value of advanced organizers or making clear the role for mastery of necessary prerequisites.
  • We do recognize there may be times when self-directed opportunities are minimal, such as when involved in collaborative learning or when learning entirely new content, but believe that the assumption of personal responsibility is possible in ways not tied to the type of learning or content.
