Three teaching ideas are presented: how to present changes between scientific notation and decimal form that eliminate some student confusion; an analysis of an incorrect algebra equation that produced a correct answer; and aspects of a standard calculus problem dealing with minimum and maximum values. (MP)

Two supplementary calculus classes for high school students are described. Both classes were projects sponsored by the Study of Mathematically Precocious Youth (SMPY) of Johns Hopkins University. (MP)

The issue of whether to teach calculus in the secondary school is discussed in a historical context and related empirical studies are reviewed. (MK)

Testing of junior and senior business students on algebra, calculus, and statistics problems revealed they retained little of what was covered in basic quantitative courses. Emphasis on student evaluation of teachers may create incentives for instructors to avoid challenging students in these courses. (SK)

Describes a simple experiment that uses a CCD video camera, a display monitor, and a laser-printed bar pattern to illustrate signal sampling problems that produce aliasing or moiri fringes in images. Uses the Fourier transform to provide an appropriate and elegant means to explain the sampling theorem and the aliasing phenomenon in CCD-based…

Considers the perspective that method is independent of subject matter and that certain areas might be better conceived of in terms of signs and interpretations rather than in terms of objects and interactions. Contains 32 references. (DDR)

Illustrates the qualitative nature of the differences between reform courses and traditional courses based on the types of student questions and comments generated in reform classes ranging from college algebra to multivariable calculus. (AIM)

Presents an activity in which students predict the growth of the population of the United Stated using three different models. (Author/NB)

Analyzes Likert attitude questionnaires given to 28 engineering students during their first semester at a Venezuelan university. Investigates the evolution of students' attitudes when in laboratory sessions using the DERIVE Computer Algebra System (CAS). Suggests that use of DERIVE symbolic calculus software has a positive influence on attitudes…

Investigates ways to analyze change in various contexts. Focuses on computer technology providing contexts for children's investigations of patterns of change and helping to develop foundational ideas of algebra and calculus. Discusses relationships between patterns of change, fundamental algebraic notions as linear and nonlinear functions, and…

Describes the development of a model for improving the calculus achievement of minority group college students currently used by 25 institutions of higher learning. Utilizes group study and an "honors class," rather than a remedial approach. (FMW)

Offers an approach to the understanding and to the teaching of the fundamental theorem of calculus. Stresses teaching the relation between a function and its derivative and the functions themselves. (YP)

Four of the author's favorite calculus word problems are presented. These aid students in recognizing and applying concepts in contexts unlike those in typical textbook problems. (MNS)

By developing a sequence of mathematical models of harmonic motion, shows that mathematical models are not right or wrong, but instead are better or poorer representations of the problem situation. (MKR)

A preservice teacher education course involving the applications for a computer within the mathematics classroom is described in terms of its evolution from a workshop to a regular curricular offering. Included are samples of computer experiments which suggest computer teaching activities for the prospective teacher lacking in field experience.…
