A satire of traditional algebraic word problems. (MKR)

Given a multiplicative group of nonzero elements with order n, the explicit relationship between the number of cyclic subgroups of order d, which divides n, is used in the proof concerning the cyclic nature of that given multiplicative group. (JJK)

Discards the blinders that have hampered the traditional teaching of calculus and reexamines some of the intuitive ideas that underlie this subject matter. Analyzes the various indeterminate forms that arise through the blind application of algebraic operations. (Author/ASK)

Explores the ramifications of two three-year-long experiences with different pedagogical approaches to beginning algebra. Focuses on differences in the nature of subject matter understandings and explores the impact on the teacher to support students' classroom exploration of mathematical ideas. (Contains 58 references.) (Author/ASK)

Reacts to an article published in a previous issue of this journal on the effects of graphing calculators and computer algebra systems (CAS) on students' manual calculation skills. Asks enthusiasts of CAS to learn from history and avoid pitfalls. (ASK)

Describes activities for Technical Algebra, which provides students an opportunity to solve algebraic problems through a hands-on, instructional process. (MKR)

College students (n=32) in their first abstract algebra course were asked to list elements and find the product of 2 elements in the dihedral group D4. Most students found solutions using a combination of visual approaches and analytic strategies. Proposes an alternative model, the Visualizer/Analyzer model, which assumes visualization and…

Introduces an algebra lesson plan on two people saving money over the course of a week and the problems they encounter for early elementary school students. (YDS)

Discussion of XML focuses on a description of Tequyla-TX, a typed text retrieval query language for XML documents that can search on both content and structures. Highlights include motivations; numerous examples; word-based and char-based searches; tag-dependent full-text searches; text normalization; query algebra; data models and term language;…

One of the workshops at the 10th SNM Stowarzyszenie Nauczcieli Matematyki (SNM) conference was entitled: Do we really need algebra? The workshop members were given several problems to consider. By doing these problems and reflecting on them the participants explored some important aspects of the question posed. Moreover they became aware of a…

The Chebyshev polynomials named after a Russian mathematician, Pafnuty Lvovich Chebyshev, have various mathematical applications. A process for obtaining Chebyshev polynomials, and a mathematical inquiry into the patterns they generate, is presented.

An attempt to implement problem solving as a teacher of ninth grade algebra is described. The problems selected were not general ones, they involved combinations and represented various situations and were more complex which lead to the discovery of Steiner triple systems.

Participants at the Summer Institute Pattern Exploration: Integration Math and Science in the Middle Grades used and developed a method treat arithmetic, algebra and geometry as one entity. The use of iterative geometric constructions is seen to reinforce the concepts of exponents, ratios and algebraic expressions for the nth stage of the…

In addition to looking for applications that can be profitably examined algebraically, numerically and geometrically it is also helpful to use ideas that typical students might find interesting. Most secondary students are eager to obtain their driving license and part of becoming a good driver is understanding how long it takes to stop your…

The author examined the effect of demographic variables and attitudes on achievement of 8th-grade algebra students. Participants (N = 107) in 4 classes completed a questionnaire that determined demographic characteristics. They also completed attitude scales at the beginning and end of the school year. Dependent measures were the North Carolina…
