Why You Should Be Excited About the New Record for the Largest Prime Number - 2 views

  •  
    "Late last month, Curtis Cooper of the University of Central Missouri moved one small step closer to Euclid's infinity, when he announced that 257,885,161-1 is prime. This is now the largest known prime number, eclipsing the previous record-holder, which had been discovered at UCLA in 2008. The new number has 17,425,170 digits-just writing them down makes for a 22.45-megabyte text file. The UCLA number had knocked an earlier number of Cooper's, from 2006, out of the record books. "

Mothers Talk Less to Young Daughters About Math - 4 views

  •  
    University of Delaware researchers find: "Even [when their children are] as young as 22 months, American parents draw boys' attention to numerical concepts far more often than girls'. Indeed, parents speak to boys about number concepts twice as often as they do girls. For cardinal-numbers speech, in which a number is attached to an obvious noun reference - "Here are five raisins" or "Look at those two beds" - the difference was even larger. Mothers were three times more likely to use such formulations while talking to boys."

Pigeons match primates in number sense - 15 views

  •  
    Pigeons "were taught to order 35 different sets of images, all of which displayed one, two, or three items. Then, the setup changed: values up to nine were introduced. The pigeons were then shown a pair of two familiar numbers (such as two and three), one familiar and one unfamiliar number (such as one and seven), or two unfamiliar numbers (such as five and eight).

Design of the Learning Module for Math Quest: A Role Playing Game for Learning Numbers - 13 views

  •  
    "Math Quest is a role playing game that could be used as a tool to learn numbers and basic
    mathematic operations. The Math Quest package consists of two main modules; learning and game modules
    that can be executed separately. The use of the learning module as a tool in learning will allow for a highly
    individualized and interactive environment. This paper presents the design of the learning module for
    numbers and their mathematics operation. Due to its interactive and stimulating nature, the module is suitable
    for school children age 9 to 12 years old to learn the subject. The development takes into consideration of
    constructivism learning theories where learning is based on students' active participation in problem solving
    and critical thinking regarding activity that they are involved in. The framework for each of module is as
    follows: objectives, concept, examples, exercises, quizzes. A heuristic evaluation on the design was
    conducted and positive feedback was obtained."

  •  
    According to Nancy Kimberly of HASTAC, this set of video games won the 1st National STEM Video Game Challenge: "Numbaland!, produced by graduate students Derek Lomas of Carnegie Mellon University, Dixie Ching of New York University and Jeanine Sun of the University of California at San Diego, was the winner of the Collegiate and Impact Prizes and will receive $50,000 in total. The collection of four games allows children in kindergarten to grade 4 to construct a set of skills that helps develop their sense of number concepts"

Language May Play Important Role in Learning the Meanings of Numbers - 3 views

  •  
    Experiments by University of Chicago psychologists with deaf people in Nicaragua who learned "homesigns" rather than formal sign language, could not count beyond three. In contrast, people learning sign language learn number words and number concept and understand large numbers. The findings ""suggest that language is an important player in number acquisition." The research is reported in PNAS: http://www.pnas.org/content/early/2011/01/31/1015975108.abstract
