 AllRefer.com - group (Mathematics) - Encyclopedia
The real numbers (see number) form a commutative group both under addition, with 0 as identity element and -a as inverse, and, excluding 0, under multiplication, with 1 as identity element and 1/a as inverse.
The elements of a group need not be numbers; they may often be transformations, or mappings, of one set of objects into another.
Group theory has wide applications in mathematics, including number theory, geometry, and statistics, and is also important in other branches of science, e.g., elementary particle theory and crystallography.

 Combining Individual and Group Evaluations
Mathematics classes are small, with a maximum of 20 students in calculus sections and even fewer students in upper level courses.
Seven of ten problems on one discrete mathematics group test asked students to determine whether a statement is true or false and to provide either a proof or counterexample with a full explanation; one such statement was: The square of an integer has the form 4k or 4k + 1 for some integer k.
The group assignments, which vary with each course, comprise challenging problems that are submitted and graded Students in all the courses have time to become acclimated to the course before the individual work counts heavily, and no students have withdrawn from my Calculus I classes in recent years.

Applied Mathematics and Theoretical Mathematics) lead to the degree Bachelor of Science in Mathematics, and the fourth (Mathematics with Computer Science) to the degree Bachelor of Science in Mathematics with Computer Science.
Applied mathematics is the mathematical study of general scientific concepts, principles, and phenomena that, because of their widespread occurrence and application, relate or unify various disciplines.
Theoretical mathematics (or "pure" mathematics) is the study of the basic concepts and structures that underlie the mathematical tools used in science and engineering.

 ADEA: Working Group on Mathematics and Science Education
The Working Group on Mathematics and Science Education (WGMSE) was created in November 2004 to contribute to the improvement of Africa's mathematics and science education (MSE) programs and their greater adaptation to the challenges of the 21st century.
Every year, the working group will train a number of trainers in MSE from selected countries to strengthen institutional capacities in MSE, muster broader participation of experienced and interested participants and widen the circulation and the dissemination of the knowledge and skills in the area of mathematics and science education.
The working group seeks to upgrade the capacity of practitioners and responsible educators to improve their ability to conduct participatory evaluation and action research based on their own experience, and to be able to communicate results more widely.

 Guide to the Mathematics Subject Classification Scheme
One way to divide the mathematics literature is to decide which books and articles are designed to reveal the structure of mathematics itself, and which are intended to apply mathematics to closely allied areas.
Algebra is principally concerned with symmetry, patterns, discrete sets, and the rules for manipulating arithmetic operations; one might think of this as the outgrowth of arithmetic and algebra classes in primary and secondary school.
The second broad part of the mathematics literature includes those areas which could be considered either independent disciplines or central parts of mathematics, as well as those areas which clearly use mathematics but are interested in non-mathematical ideas too.

 Group Theory at the Library of Math (Free Online Mathematics)   (Site not responding. Last check: )
One of the main unifying themes in mathematics, group theory originated from concrete examplesinvolving the study of polynomials in the earlypart of the 1800's.
In this topic, many examples are given to explain the importance of permutation groups when the underlying set is a finite set of counting numbers; and the matrix form and cycle notation of such permutations are detailed so as to fully explore the groups of permutations of finite sets of counting numbers (called symmetric groups).
Basically, the center of a group is the collection of elements in the group that commute with all elements in the group and the centralizer of a given element in the group is the collection of all elements in the group that commute with that given element.

 Math Forum: Learning and Mathematics: Small group interactions - Yackel, Cobb, & Wood
Children were grouped in pairs and spent half of each math period working together to solve math problems.
Work was not graded, nor was there a set amount of work to be completed; rather, the teacher gave report card grades based on her knowledge of the children, and the students were allowed to spend as much time as they needed to discuss each problem and arrive at a solution.
Thus the authors believe that social situations are crucial in mathematics instruction, especially with regard to allowing the child to construct and modify his or her own mathematical knowledge.

 The Math Forum - Math Library - Group Theory
Group theory can be considered the study of symmetry: the collection of symmetries of some object preserving some of its structure forms a group; in some sense all groups arise this way.
Group theory takes an abstract approach, dealing with many mathematical systems at once and requiring only that a mathematical system obey a few simple rules, seeking then to find properties common to all systems that obey these few rules.
