The Effects of Two Generative Activities on Learner Comprehension of Part-Whole Meaning of Rational Numbers Using Virtual Manipulatives
… achievement of the part-whole representation of rational numbers while using virtual manipulatives. Third-grade students were divided randomly in two groups to evaluate the effects of two generative learning activities: answering-questions and generating-examples while using two virtual …

The relationship between estimation skill and computational ability of students in years 5, 7 and 9 for whole and rational numbers
… skill and computational ability for whole and rational numbers. The methods carried out were both quantitative as well as qualitative and data were collected from three primary schools along with their associated high school in the Perth area. The year levels chosen were 5, 7 and 9. There were …

Use of learning-logs in high school pre-algebra classes to improve mastery of rational numbers and linear equations for high-risk minority students
The purpose of this study was to determine whether there was a relationship in the use of learning-logs to traditional or current math instruction in secondary school pre-algebra classes to improve the mastery of single-variable equations by high-risk minority students.

RATIONAL POINTS ON SOME FAMILIES OF ELLIPTIC CURVES
… curve over Q(m). (Here Q represents the field of rational numbers.) Brown and Myers show that a certain quadratic polynomial m(t) has the property that E_m(t) contains an additional rational point that is independent from the two original generators. This implies that there are infinitely many …

On the Units and the Structure of the 3-Sylow Subgroups of the Ideal Class Groups of Pure Bicubic Fields and their Normal Closures
If we adjoin the cube root of a cube free rational integer <i>m</i> to the rational numbers we construct a cubic field. If we adjoin the cube roots of distinct cube free rational integers <i>m</i> and <i>n</i> to the rational numbers we construct a bicubic field. The number theoretic invariants for …

The Fermat equation over quadratic fields
… Kummer's work on Fermat's Last Theorem over the rational numbers to quadratic fields. In particular, under certain congruence conditions it is shown that the Fermat equation of exponent p has no solution over Q(√m) when p is a m-regular prime. Completely analogous to the work of Kummer, it is …

Un ejemplo de teoría de homotopia en los grupos abelianos

The Birch and Swinnerton-Dyer Conjecture for elliptic curves
… a characterisation for elliptic curves over rational numbers. We investigate the group structure of rational points on elliptic curves, and show that this group is finitely generated by the Mordell-Weil Theorem. The Shafarevich-Tate group is introduced by way of an example. Thereafter, with …

Real Algebraic Geometry of the Sextic Curves
… related to space sextics over the field of real numbers. In particular, we find an example of a space sextic with 120 totally real tritangent planes, which answers a historical problem originating from Arnold Emch in 1928. The last part of this thesis is an algebraic study of a real optimization …

On Weak Number Theories
… ring of integers of a finite extension of rational numbers. In Chapter 3 we give a necessary condition for a set to be (FOR ALL)('n)(THERE EXISTS)-diophantine definable over R. From this necessary condition we can show that many subsets of R including N and cofinite subsets, are not (FOR …

L-functions of twisted elliptic curves over function fields

The complexity of optimal mechanism design
