The student then places it on the playing field. The system allows a chosen playing card to be dragged by means of a mouse to the playing field and, if properly placed, to "stick" in place on the playing field. (Improperly placed cards "snap" back to their original file position.) After each card has been correctly placed, a line between properly placed cards is generated connecting proper statements and reasons to each other and the GIVEN or CONCLUSION displays the completed proof (Herbst, 2002).
In working with geometric proofs, it is important for the student and teacher alike to approach this new and intimidating subject with an open mind. Even though students may have never experienced any type of logic or reasoning prior to the introduction of proofs, if presented correctly, this new way of approaching math can be both fun and enlightening. Teachers should keep this in mind when approaching a new class with the concepts of proof for the first time. Not only is patience required, but sometimes unorthodox teaching methods may be necessary to get students pointed in the right direction.
Proofs are not something that everyone will...
Fractal Geometry is a somewhat new branch of mathematics that was developed in 1980 by Benoit B. Mandelbrot, a research mathematician in I.B.M.'s Thomas Day Watson laboratory in New York. Mandelbrot was experimenting with the theories of Gaston Julia, a French mathematician when he discovered the fractal set was discovered. Julia dedicated his life to the study of the iteration of polynomials and rational functions. Around the 1920s, Julia published a
Atheist In "On Being an Atheist," H.J. McCloskey discusses what it means to him to be an atheist. In doing so, he criticizes the classical argument in favor of God's existence. This is not a new criticism, as people have been arguing about whether it is possible to prove or disprove the existence of God for years. However, McCloskey goes further in his argument against the existence of God by
Note the distinct similarities. An examination of Escher's Circle Limit III can thus tell us much about distance in hyperbolic geometry. In both Escher's woodcut and the Poincare disk, the images showcased appear smaller as one's eye moves toward the edge of the circle. However, this is an illusion created by our traditional, Euclidean perceptions. Because of the way that distance is measured in a hyperbolic space, all of the
For instance, classical mathematicians by definition rely on Plato's theory of forms as the underlying basis of their mathematical worldview. The Platonist assumes the existence of true, immutable, and universal forms and structures that the mathematician approaches through the language of numbers and equations. For instance, the classical mathematician holds to the Platonic belief in the expansion of pi; to approach the expansion of pi from any other perspective
relearn several mathematical concepts and learn how to instruct other about them. It also became necessary to learn the different components of educating students on math based upon their current knowledge and abilities and how the teacher will evaluate the students to make that determination. Not only did I learn how to teach the subject, but I was also instructed on how to submit and fulfill standards. In short,
Empiricism Whenever a person chooses a side in the traditional debate between rationalism and empiricism, that person is necessarily making a statement about how much people should trust the evidence of their own senses. However, there are a number of instances in which I think that sensory evidence can be deceptive. While I think the allure of empiricism is undoubtedly seductive, for the precise reason that sensory experience can be so
