The predicted and actual achievement in college calculus is compared for students who had studied two semesters of calculus in high school. The regression equation used for prediction was calculated from the performance data of similar students who had not had high school calculus. (CT)

A discussion of the mathematics of rugby is related to an earlier article about mathematics and the physical world. (MP)

Some ways to link calculus instruction with the mathematical models used in physics courses are presented. The activity of modelling is presented as a major tool in synchronizing physics and mathematics instruction in undergraduate engineering programs. (MP)

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…
